However, Israel is also a global leader (21)______ innovation.According to the World Economic Forum‟s Global Competitiveness Report 2016-2017, Israel is the second (22)______ (innovative) nation in the world, just after Switzerland.Many of us (23)______ not be aware, but technologies developed in Israel have changed our lives. For example, antivirus software (24)______ protects our computers was first developed in Israel in the 1970s, according to The Telegraph. In addition, features on our mobile phones such as voicemail and SMS were also developed in Israel.So it comes as no surprise that Israel plans to use its innovative strength (25)______ (power) the cooperation with China in the Belt and Road Initiative. (26)______ ______ ______ Israel is needed, it will spare no effort to contribute to the project, said Israeli Prime Minister Benjamin Netanyahu during his visit to China in March, according to Xinhua News Agency.Many Israeli environmental technology companies have already set up facilities in Shandong province, (27)______ (bring) Israeli techniques to many areas such as recycling water for agricultural use, reported the Times of Israel.(28)______ (found) on very dry land, Israel had been worried about water for a very long time. However, in recent years, the quality and quantity of water in Israel (29)______ (improve), with the help of techniques that turn Mediterranean seawater and wastewater into usable water.In fact, such innovations have led to more and more Chinese students (30)______ (seek) quality higher education in Israel. “When Chinese students who study here go back home, they will be in positions to influence China-Israel relationships in the future,” Emma Afterman, manager of Israel-China Academic Relations at the Council for Higher Education, told the Jerusalem Post.Parents have been concerned about their kids‟ use of technology since the dawn of technology – or at least since the invention of the transistor radio in the 1950s. Today, technology is everywhere, and kids are growing up __31__ to their smartphones, tablets and laptops in ways that …50s moms and dad s could never have dreamed of. Parental concern has grown along with this tech __32__. But now, even those in the industry are wondering if technology has taken a truly __33__ hold on all of us – and especially children.No less than Melinda Gates, wife of Microsoft founder Bill Gates, wrote an editorial in the Washington Post last summer expressing regret for the Pandora‟s Box she and her husband helped open. “I spent my career in technology.I wasn‟t prepared for its effect on my kids,” she wrote. “Phones and apps aren‟t good or bad by themselves, but for adolescents who don‟t yet have the emotional tools to deal with life‟s complication and __34__, they can add to the difficulties of growing up.”A study, which came out this year, looked at yearly surveys of 8th, 10th, and 12th graders in the U.S. between 1991-2016, and __35__ markers of psychological well-being, such as self-esteem, life satisfaction and happiness. It found that such well-being suddenly decreased after 2012 – just at the time that the use of smartphone and social media __36__. There was a direct correlation between the amount of time spent on electronics and unhappiness. Happiness was highest among kids who participated in sports, followed by in-person socializing and __37__ services. The lowest? Online computer games –the abuse of which has recently been __38__ a recognized mental health disorder by the World Health Organization – and social media.Early this year, big players formerly of tech companies such as Google and Facebook created the Center for Humane Technology and, in partnership with the nonprofit organization Common Sense Media, __39__ a full media and advertising attack on the very industry they had a hand in building. Their initiative, the Truth about Tech, is pouring millions of dollars into a(n) __40__ to warn parents, teachers and students that the technology they use is in fact engineered to addict them.III. Reading ComprehensionSection AIf you could be anybody in the world, who would it be? This is usually just a theoretical question. The idea of suddenly taking the form of your neighbor, a celebrity or even your dog is fun to think about, but seemingly impossible to __41__.Yet a few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality device. “The first seconds are just overwhelming,” says Rikke Frances Wahl, a woman who __42__ became a man. “It feels mysterious. You start to feel more and more comfortable in it, and you start to really get the __43__ of how it would be if it were your body.”Wahl, an actress, model and artist, was one of the participants in a body swapping(替换) experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She __44__ her new body using a machine called The Machine to be Another. The set-up is relatively simple. Both users put on a virtual reality headset with a camera installed to the top of it. The video from each camera is piped to the other person, so what you see is the exact view of your __45__. If she moves her arm, you see it. If you move your arm, she sees it. To get used to seeing another person‟s body without actually having control of it, participants start by moving their arms and legs very slowly, so that the other can follow along. __46__, this kind of slow, synchronized(同步) movement becomes comfortable, and participants really start to feel as though they were living in another person‟s body. “It was so natural,” Wahl says, laughing, “and at the same time it was so unnatural.”Interestingly, using such technology __47__ to alter people‟s behaviour afterwards – potentially for the better. Studies have shown that virtual reality can be __48__ in fighting implicit racism(隐性种族歧视). Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people‟s associations between.Another study showed that using the so-called “rubber hand illusion(错觉)” can have the same __49__. When that rubber hand is a colour unlike their skin, participants __50__ lower on tests for implicit racism than when they watched a hand of the same skin colour.The idea is that once you‟ve “put yourself in another‟s shoes” you‟re less likely to think __51__ of them, because your brain has __52__ the feeling of being that person.Wahl says that she‟d jump at the chance to swap bodies with someone again. “I would really, really __53__ it to everyone, everyone should try this thing,” she says. “We all have different feelings and points of views about things,” says Pointeau, “and it‟s really strongly related to our __54__ experience. With this kind of experience we can __55__ empathy – the action of understanding, but also maybe help people better understand themselves too.”41. A. execute B. excuse C. explore D. exhibit42. A. contemporarily B. permanently C. temporarily D. secretly43. A. passion B. fantasy C. familiarity D. energy44. A. inherited B. altered C. endured D. acquired45.

A. endure B. promote C. honor D. identifySection B(A)A British hospital director told me he was hunting for staff to replace the foreign doctors and nurses leaving because of Brexit(脱欧). He hadn‟t found many qualified Britons queuing to replace them.In an age when the “war for talent” is a global business trend, the UK is fighting a war against talent. But if I were a Brexiter, I‟d say: Brexit should be the prompt for Britain to finally start training enough of its own talent. If UK wants to avoid economic decline, it will need to train far more of its own nurses, construction workers, architects, etc. For a country whose policy has always been not to educate the working class, that would be a reversal of history.Before Brexit, high-skilled immigrants staffed world-class British sectors such as the City of London and the creative economy. In healthcare, the UK developed a brilliant way: let a poor country like Roma nia fund a nurse‟s education, then underpay her to look after sick Brits. Low-skilled immigrants eager to work all hours for little money gave the UK cafes and corner shops that seldom closed. Low-skilled Britons could have done these jobs, but mostly didn‟t.The coming wave of British talent is largely immigrant too: the kids who have made London‟s state schools the UK‟s best, plus the offspring of Russian, Chinese and other foreign elites(精英) who fill private schools. Many of these would love to stay and make the UK richer.But Brexiters want to cut immigration. The obvious solution: equip working-class Brits to do jobs from nursing to banking. Jonathan Portes, economics professor at King‟s College said: “The problem of UK vocational education has been k nown for at least a century. We‟ve always neglected it.” In fact, in August the UK removed the state bursary(助学金) for people training to be nurses, midwives and speech therapists. Students now have to fund courses themselves, then earn a low salary for a lifetime.If Britain doesn‟t upskill its workers fast, it will lose skilled jobs. It will continue to have the world‟s best universities per capita only if it can find enough Britons to replace foreign academics who leave the UK. Much the same applies to finance or design. Meanwhile, low-skilled foreign fruit pickers have already melted away since the pound plunged. With few Britons queuing to replace them, much of this year‟s produce rotted in the fields.So the likely post-Brexit outcome is a UK that cannot keep itself in the style to which it has become accustomed. The war against talent will probably leave Britain looking a bit more like today‟s English seaside towns, or most of the country in the 1970s: culturally homogeneous(同种类的), relatively poor and under-serviced.56. The UK is fighting a war against talent because ______.A. skilled immigrants leave the country after BrexitB. it doesn‟t have enough fund to train its own citizensC. too many qualified Britons are queuing for creative jobsD. it is trying a different approach to attracting talent57. Which is FALSE about the situation in the UK before Brexit?A. Hospital employed many immigrant nurses.B. Much attention was paid to the nurse training.C. Many Brits were unwilling to do low-paid jobs.D. Immigrant elites could find creative and decent jobs.58. What can we learn from the passage?A. Most well-educated immigrants had no plan to stay in the UK.B. The government now gives nurses-to-be some financial support.C. A lot of fruits rotted in the fields for the lack of skilled fruit pickers.D. The outflow of talent only existed in the field of education and healthcare.59. According to the writer, the post-Brexit Britain is likely to ______.A. be as rich and powerful as it used to beB. be as convenient as it was before BrexitC. be different in style but the same in essenceD. go backward in economy and social service(B)FreethisThe DJI Mavic Pro folds down as small as a bottle ofyou New OcuSync transmission system offers up to 7km offeaturessensor DJI Spark Alopine White with Extra Battery &ANDmovingRecord ultra-stable Full HD footage and 12MP stills Measures approximately the same size as can of popD14.3cmFreeActiveavoidstabilityProFlight Maverick Folding Camera Drone WithIt folds away small enough to fit into your backpackTap a button to take off.

NASA and the GLOBE Program are inviting you to take part in a citizen science cloud observation challenge. The GLOBE Program is an international science and education program that provide students and the public with the opportunity to participate in data collection and the scientific process.From March 15 through April 15, citizen scientists of all ages can make up to 10 cloud observations per day using the GLOBE Observer app or one of the other data entry options (for trained GLOBE members). Challenge participants with the most observations will be congratulated by a NASA scientist in a video posted on the GLOBE Program‟s website and on social media.“The GLOBE Progra m is offering this challenge to show people how important it is to NASA to have citizen scientist observations: observations from the ground up,” said Marile Colon Robles, lead for the GLOBE Clouds team at NASA‟s Langley Research Center in Hampton, Virginia. “We‟re going from winter to spring, so the types of storms will change, which will also change the types of clouds.”Researchers use, and value, this citizen science cloud data because it helps to validate data from Earth-observing instruments. Scientists at Langley work with a set of six instruments known as the Clouds and the Earth‟s Radiant Energy System (CERES).Even though CERES‟ instruments use advanced technology, it is not always easy for researchers to positively identify all types of clouds in their images. For example, it can be difficult to differ thin, wispy cirrus clouds(细小的卷云) from snow since both are cold and bright; even more so when cirrus clouds are above a surface with patchy snow(片状雪) or snow cover. One solution to this problem is to look at satellite images from a particular area and compare them to data submitted by citizen scientists on the ground.“Looking at what an observer recorded as clouds and looking at their suface observations really helps us better understand the images that were matched from the satellite,” said Colon Robles.You don‟t have to be a cloud-gazing professional to participate. For those who want to be part of the challenge but don‟t have a lot of experience identifying clouds, Colon Robles offers the following advice: “Just go outside.” The more clouds you observe, she said, the more comfortable you‟ll be collecting data.63. Why do researchers launch the cloud observation challenge?A. The GLOBE Program is badly short of hands.B. The technology CERES uses is not that advanced.C. Scientists can compare data from different instruments.D. Cirrus clouds are difficult to identify when with snow cover.64. The underlined word “validate” is closest in meaning to ______.A. createB. cancelC. countD. confirm65. Which of the following is TRUE?A. Citizen observers can only submit their data by means of an app.B. Observers submitting the most observations can get a special prize.C. Observations from the ground are not as valuable as satellite images.D. The data collected by citizen scientists will be posted on social media.66. Which is the best title for the passage?A. NASA Employs New members.B. Cloud Activities Bring a New Challenge.C. Citizens Gain Experience through Observation.D. Professionals Teach You to Observe Clouds.A new report by the World Bank shows that the effects of climate change could force 140 millionpeople to move within their countries by 2050.The report looked at three developing regions of the world –sub-Saharan Africa, South Asia andLatin America. ___67___Climate migrants are people who are forced to move within their country because of water scarcity, crop failure, rising sea levels and storm surges due to climate change.___68___ It is important to help people make good decisions about whether to stay where they are or move to new locations where they are less vulnerable.The report noted that the effects of climate change will often force people to move from rural areas suffering from droughts or crop failures to cities where there are diffe rent opportunities. ___69___ “Without the right planning and support, people migrating from rural areas into cities could be facing could be facing new and even more dangerous risks,” said Kanta Kumari Rigaud, the report‟s team lead.“___70___” Rigaud added.The report recommends key actions to help prevent wide-scale climate migration: cutting global greenhouse gas emissions; improving development planning at the local level for climate migration; and investing in data to better understand climate migration trends in each country. The report notes that any rise in climate migration will be in addition to millions of other migrants within countries, moving for economic, social, political or other reasons.Ⅳ. Summary WritingIt is universally true that all parents in the world love their children. However, as parents' views of life vary, they show their love in different ways.The monarch type of parents are intolerant and self-centered. They lay down regulations in the family for their children to observe. Furthermore,they insist that their children should act upon them without question. With a firm belief in their own philosophy of life, they have litter respect for others‟ opinions, least of all, their children's. The sen tence they say most frequently to their children is, “you should do this.”Contrary to the monarch-type parents, the servant-type parents revolve around their children all the time. They are soft, good-nature, and easy-going. They never deny their children any wish, and cheerfully run to buy anything their children ask for. They are happy so tong as their children are content. With the sincere belief that love means sacrifice, they are ready to give up anything for their children's sake. With their children at the center of their lives, they always ask, “What else can we do for you?”The friends-type parents, as the term implies, treat their children as friends. They are generous and wise. Like good friends, they discuss with their children the latest news, share their children's interests, and listen attentively to their children's expression of emotion, whether it is anger, fear, joy or sorrow. They have a close relationship with their children while sticking to their principled stand. They discuss problems with their children rather than provide ready solution. They respect their children as their equals. They often say: “Let's put our heads together and see what we can do.”There is no doubt that children welcome the third type of parents, for a free, friendly, and sympathetic atmosphere at home is most favorable to the development of youngsters both in body and in mind. All parents should re-examine and change some of their ways of showing their love if they want their children to grow up happily and healthily.Ⅴ. Translation72. 据报道数以百计的消防员正在参加营救行动。

Each word can be used only once. Note that there is one word more than you need.Parents have been concerned about their kids' use of technology since the dawn of technology – or at least since the invention of the transistor radio in the 1950s. Today, technology is everywhere, and kids are growing up __31__ to their smartphones, tablets and laptops in ways that '50s moms and dads could never have dreamed of. Parental concern has grown along with this tech __32__. But now, even those in the industry are wondering if technology has taken a truly __33__ hold on all of us –and especially children.No less than Melinda Gates, wife of Microsoft founder Bill Gates, wrote an editorial in the Washington Post last summer expressing regret for the Pandora's Box she and her husband helped open. "I spent my career in technology. I wasn't prepared for its effect on my kids," she wrote. "Phones and apps aren't good or bad by themselves, but for adolescents who don't yet have the emotional tools to deal with life's complication and __34__, they can add to the difficulties of growing up."A study, which came out this year, looked at yearly surveys of 8th, 10th and 12th graders in the U.S. between 1991-2016, and __35__ markers of psychological well-being, such as self-esteem, life satisfaction and happiness. It found that such well-being suddenly decreased after 2012 – just at the time that the use of smartphone and social media __36__.

Their initiative, the Truth about Tech, is pouring millions of dollars into a(n) __40__ to warn parents, teachers and students that the technology they use is in fact engineered to addict them.III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.If you could be anybody in the world, who would it be? This is usually just a theoretical question. The idea of suddenly taking the form of your neighbor, a celebrity or even your dog is fun to think about, but seemingly impossible to ___41___.Yet a few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality device. “The first sec onds are just overwhelming,” says Rikke Frances Wahl, a woman who ___42___ became a man. “It feels mysterious. You start to feel more and more comfortable in it, and you start to really get the ___43___ of how it would be if it were your body.”Wahl, an actress, model and artist, was one of the participants in a body swapping(替换) experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She ___44___ her new body using a machine called The Machine to be Another. The set-up is relatively simple. Both users put on a virtual reality headset with a camera installed to the top of it. The video from each camera is piped to the other person, so what you see is the exact view of your___45___. If she moves her arm, you see it. If you move your arm, she sees it. To get used to seeing another person’s body without actually having control of it, participants start by moving their arms and legs very slowly, so that the other can follow along. ___46___, this kind of slow, synchronized (同步) movement becomes comfortable, and participants really start to feel as though they were living in another person’s body. “It was so natural,” Wahl says, laughing, “and at the same time it was so unnatural.”Interestingly, using such technology ___47___to alter people’s behaviour afterwards – potentially for the better. Studies have shown that virtual reality can be ___48___ in fighting implicit racism (隐性种族歧视). Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people’s associations.Another study showed that using the so-called “rubber hand illusion(错觉)” can have the same __49__. When that rubber hand is a colour unlike their skin, participants ___50___lower on tests for implicit racism than when they watched a hand of the same skin colour.The idea is that once you’ve “put yourself in another’s shoes” you’re less likely to think ___51___ of them, because your brain has ___52___ the feeling of being that person.Wahl says that she’d jump at the chance to swap bodies with someone again. “I would really, really ___53___ it to everyone, everyone should try this thing,” she says. “We all have different feelings and points of views about things,” says Pointeau,“and it’s really strongly related to our ___54___ experience. With this kind of experience we can ___55___empathy –the action of understanding, but also maybe help people better understand themselves too.”41. A. execute B. excuse C. explore D. exhibit42.

A. endure B. promote C. honor D. identify Section BDirections:Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)A British hospital director told me he was hunting for staff to replace the foreign doctors and nurses leaving because of Brexit(脱欧). He hadn’t found many qualified Britons queuing to replace them.In an age when the “war for talent” is a global business trend, the UK is fighting a war against talent. But if I were a Brexiter, I’d say: Brexit should be the prompt for Britain to finally start training enough of its own talent. If UK wants to avoid economic decline, it will need to train far more of its own nurses, construction workers, architects, etc. For a country whose policy has always been not to educate the working class, that would be a reversal of history.Before Brexit, high-skilled immigrants staffed world-class British sectors such as the City of London and the creative economy. In healthcare, the UK developed a brilliant way: let a poor country like Romania fund a nurs e’s education, then underpay her to look after sick Brits. Low-skilled immigrants eager to work all hours for little money gave the UK cafes and corner shops that seldom closed. Low-skilled Britons could have done these jobs, but mostly didn’t.The coming wave of British talent is largely immigrant too: the kids who have made London’s state schools the UK’s best, plus the offspring of Russian, Chinese and other foreign elites(精英)who fill private schools. Many of these would love to stay and make the UK richer.But Brexiters want to cut immigration. The obvious solution: equip working-class Brits to do jobs from nursing to banking. Jonathan Portes, economics professor at King’s College London said: “The problem of UK vocational education has been known for at least a century. We’ve always neglected it.” In fact, in August the UK removed the state bursary(助学金)for people training to be nurses, midwives andspeech therapists. Students now have to fund courses themselves, then earn a low salary for a lifetime.If Britain doesn’t upskill its workers fast, it will lose skilled jobs. It will continue to have the world’s best universities per capita only if it can find enough Britons to replace foreign academics who leave the UK. Much the same applies to finance or design. Meanwhile, low-skilled foreign fruit pickers have already melted away since the pound plunged. With few Britons queuing to replace them, much of this year’s produce rotted in the fields.So the likely post-Brexit outcome is a UK that cannot keep itself in the style to which it has become accustomed. The war against talent will probably leave Britain looking a bit more like today’s English seaside towns, or most of the country in the 1970s: culturally homogeneous(同种类的), relatively poor and under-serviced.56. The UK is fighting a war against talent because ______.A. skilled immigrants leave the country after BrexitB. it doesn’t have enough fund to train its own citizensC. too many qualified Britons are queuing for creative jobsD. it is trying a different approach to attracting talent57. Which is FALSE about the situation in the UK before Brexit?A. Hospitals employed many immigrant nurses.B. Much attention was paid to the nurse training.C. Many Brits were unwilling to do low-paid jobs.D. Immigrant elites could find creative and decent jobs.58. What can we learn from the passage?A. Most well-educated immigrants had no plan to stay in the UK.B. The government now gives nurses-to-be some financial support.C. A lot of fruits rotted in the fields for the lack of skilled fruit pickers.D. The outflow of talent only existed in the field of education and healthcare.59. According to the writer, the post-Brexit Britain is likely to ______.A. be as rich and powerful as it used to beB. be as convenient as it was before BrexitC. be different in style but the same in essenceD. go backward in economy and social service(B)∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙60.

NASA and the GLOBE Program are inviting you to take part in a citizen science cloud observation challenge. The GLOBE Program is an international science and education program that provides students and the public with the opportunity to participate in data collection and the scientific process.From March 15 through April 15, citizen scientists of all ages can make up to 10 cloud observations per day using the GLOBE Observer app or one of the other data entry options (for trained GLOBE members). Challenge participants with the most observations will be congratulated by a NASA scientist in a video posted on the GLOBE Program’s website and on social media.“The GLOBE Program is offering this challenge to show people how important it is to NASA to have citizen scientist observations: observations from the ground up,” said Marilé Colón Robles, lead for the GLOBE Clouds team at NASA’s Langley Research Center in Hampton, Virginia. “We’re going from winter to spring, so the types of storms will change, which will also change the types of clouds.”Researchers use, and value, this citizen science cloud data because it helps to validate data from Earth-observing instruments. Scientists at Langley work with a set of six instruments known as the Clouds and the Earth’s Radiant Energy System (CERES).Even though CERES’ instruments use advanced technology, it is not always easy for researchers to positively identify all types of clouds in their images. For example, it can be difficult to differ thin, wispy cirrus clouds (细小的卷云) from snow since both are cold and bright; even more so when cirrus clouds are above a surface with patchy snow (片状雪)or snow cover. One solution to this problem is to look at satellite images from a particular area and compare them to data submitted by citizen scientists on the ground.“Looking at what an observer recorded as clouds and looking at their surface observations really helps us better understand the images that were matched from thesatellite,” said Colón Robles.You don’t have to be a cloud-gazing professional to participate. For those who want to be part of the challenge but don’t have a lot of experience identifying clouds, Colón Rob les offers the following advice: “Just go outside.” The more clouds you observe, she said, the more comfortable you’ll be collecting data.63. Why do researchers launch the cloud observation challenge?A. The GLOBE Program is badly short of hands.B. The technology CERES uses is not that advanced.C. Scientists can compare data from different instruments.D. Cirrus clouds are difficult to identify when with snow cover.64.

Note that there are two more sentences than you need.A new report by the World Bank shows that the effects of climate change could force 140 million people to move within their countries by 2050.The report looked at three developing regions of the world—sub-Saharan Africa, South Asia and Latin America. __________67__________Climate migrants are people who are forced to move within their country because of water scarcity, crop failure, rising sea levels and storm surges due to climate change.__________68__________ It is important to help people make good decisions about whether to stay where they are or move to new locations where they are less vulnerable.The report noted that the effects of climate change will often force people to move from rural areas suffering from droughts or crop failures to cities where there are different opportunities. __________69__________ “Without the right planning and support, people migrating from rural areas into cities could be facing new and even more dangerous risks,” said Kanta Kumari Rigaud, the report’s team lead. “__________70__________” Rigaud added.The report recommends key actions to help prevent wide-scale climate migration: cutting global greenhouse gas emissions; improving development planning at the local level for climate migration; and investing in data to better understand climate migration trends in each country. The report notes that any rise in climate migration will be in addition to millions of other migrants within countries, moving for economic, social, political or other reasons.IV. Summary WritingDirections:Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.It is universally true that all parents in the world love their children. However, as parents’ views of life vary, they show their love in different ways.The monarch type of parents are intolerant and self-centered. They lay down regulations in the family for their children to observe. Furthermore, they insist that their children should act upon them without question. With a firm belief in their own philosophy of life, they have little respect for others’ opinions, least of all, their children’s. The sentence they say most frequently to their children is, “ you should do this.”Contrary to the monarch-type parents, the servant-type parents revolve around their children all the time. They are soft, good-natured, and easy-going. They never deny their children any wish, and cheerfully run to buy anything their children ask for. They are happy so long as their children are content. With the sincere belief that love means sacrifice, they are ready to give up anything for their children’s sake. With their children at the center of their lives, they always ask, “What else can we do for you?”The friend-type parents, as the term implies, treat their children as friends. They are generous and wise. Like good friends, they discuss with their children the latest news, share their children’s interests, and listen attentively to their children’s expression of emotion, whether it is anger, fear, joy or sorrow. They have a close relationship with their children while sticking to their principled stand. They discuss problems with their children rather than provide ready solution. They respect theirchildren as their equals. They often say: “Let’s put out heads together and see what we can do.”There is no doubt that children welcome the third type of parents, for a free, friendly, and sympathetic atmosphere at home is most favorable to the development of youngsters both in body and in mind. All parents should re-examine and change some of their ways of showing their love if they want their children to grow up happily and healthily.V. TranslationDirections: Translate the following sentences into English, using the words given in the brackets.72. 据报道数以百计的消防员正在参加营救行动。
