Diana Ross was born on March 26, 1944, in Detroit, Michigan. She was the second of six children of Fred and Ernestine Ross, who lived in one of Detroit’s poor districts.

The group was renamed the Supremes after signing a recording contract (合同) with Motown late the following year.

Grandparents Peter and Chris stepped on the long journey after deciding to “do something a bit different”. They traversed (横穿) cities, deserts, mountains and everything in between across Europe, the Middle East and the East Asia. The married couple of 37 years enjoyed themselves with delicious local food and spent most nights inside a tiny tent put up wherever they could find shelter.Peter, 66, said the moment they finally had a look at the famous Great Wall after a year and a half of cycling 30 miles a day was “really exciting”. At the end of their journey, the special pair didn’t fly home but instead choose to book a cabin (舱) inside a 400m-long container ship. The final part was a three-week voyage from Singapore across the Indian Ocean and into the Mediterranean Sea before arriving at Southampton.“You never know what the day is going to bring. All you know is that you aregoing to get on your bike and cycle. Every day is an adventure and every day is new. Overall, the experience is absolutely unbelievable, ” Peter said.Peter and Chris initially set out to cycle from Britain in January 2017 but were forced home. They had cycled all the way to Hungary when Peter slipped on tiles and broke his leg. After seven months of recovery, the couple set out again in Britain. They finally arrived in China in November 2018.Both Peter and Chris agreed that the best part of the entiretrip was coming across the kindness of strangers along the way, many of whom invited the couple for food and drink.

Fine particle pollution declined rapidly following the new rules on industrial emissions and the promotion of cleanfuels, according to the study, published on Monday in the National Academy of Sciences of the United States of America. The study, which focused on the period from 2013-2017, was conducted by a group of Chinese researchers and scientists.PM2.5, as this kind of pollution is known, is so small that it can enter the bloodstream, potentially leading to cancer, stroke and heart attack in the long term. After rapid industrialization and weak regulations left the country with a reputation for smog and bad air quality, Chinese authorities started to take air pollution seriously in 2008.In 2013, Beijing had PM2.5 concentrations 40 times higher than levels recommended by the World Health Organization (WHO), and the governmentintroduced its toughest-ever clean air policies that year. The study found “signif icant declines” in PM2.5 levels across China from 2013-2017, with new standards for thermal power plants and industrial boilers, the replacement of old factories, and new emissions rules for vehicles. The authors say this “confirms the effectiveness of Chi na’s recent clean air actions.”These recent actions have seen Beijing fall out of the top 100 most-polluted cities in Asia in recent years, with the pollution levels 10% lower across Chinese cities between 2017 and 2018, according to a report by Greenpeace and AirVisual. Shanghai, the country’s largest city and financial capital, has also made environmental advances, such as adopting strict recycling regulations. Public pressure has been the driving force of pollution policy in China.Air pollution is a global issue, and India is now home to 22 of the 30 most polluted world cities, according to the Greenpeace and AirVisual report. In the US, a recent study said air pollutionwas linked to more than 107,000 deaths in 2011 and cost the country $866 billion.8. What saved many lives in China?A. China’s clean air policies.B. The increased particle pollution.C. The study by researchers.D. The reduction of the clean fuels.9. Why did PM2.5 cause many diseases?A. It was called smog.B. It made the air cleaner.C. It went into the blood.D. It had a bad reputation.10. When did Chinese government decide to treat the pollution?A. In 2008.B. In 2013.C. In 2017.D. In 2018.11. What did people in Shanghai do to protect the environment?A. They built the thermal power plants.B. They stopped using industrial boilers.C. They made Shanghai financial capital.D. They tried to recycle some rubbish.DIn the 1994 film Forrest Gump, there’s a famous saying, “Life is like a box of chocolates; you never know what you’re gonna get.” The surprise is part of the fun. Now blind box toys are bringing the magic of surprise to online shopping.A blind box toy is hidden inside uniform packaging(包装) butinvisible from the outside. You don’t know what will be inside, although the toys typically come from pop culture, ranging from movies to comics and cartoons.Blind boxes have caught on since they were first introduced from Japan to China in 2014. According to a 2019 Tmall report, the mini-series of Labubu blind box. designed by Hong Kong -born Kasing Lung, was named Champion of Unit Sales with 55,000 sold in just 9 seconds during the Singles Day shopping event. Most customers for blind boxes are young people aged 18 to 35.According to The Paper, blind box toys are popular in part because of their cute appearances. The typically cute cartoon figurines (小塑像) come in miniature (微型的) sizes, making them suitable for display almost anywhere.Even if blind boxes are not their top choice for decorations(装饰品), the mystery and uncertainty of the process also attracts people. It’s the main reason why people buy blind boxes one after another.“Fear of the unknown is always a part of the box-opening process,” said Miss Cao, 24, who lives and works in Shenyang. Speaking to Sina News, she said: “Until you open all the boxes, you cannot know what it is inside.”Opening a blind box is a delightful little surprise for our mundane daily lives, something small but fun to wait for each day, week or month. When people open this simple little box, they may be disappointed, but the uncertainty is part of the fun. People will open more blind boxes and hope for a better outcome.When someone re-makes Forrest Gump, don't be surprised if he says, “Life is like a blind box.”12.What feature of blind boxes attracts people?A.They often get toys designed by famous artists.B.They don’t know what they’ve got until they open them.C.They can learn about pop culture from the packaging.D.They can experience the excitement of online shopping.13.Why does Miss Cao love blind box toys?。

AHere are some pet-friendly universities in the UK and US.University of IllinoisStudents are allowed up to two pets in each apartment, as well as a fish tank of no more than 50 gallons.To keep a pet, you will need to get approval from the Family & Graduate housing department at the University of Illinois. You will have to provide proof that your pet is up to date with its vaccinations(疫苗), and pay a monthly US$30 pet fee, which is non-refundable(不可退款的).Your pet can’t be left for extended periods of time, and if there’s evidence that you’ve left it alone due to vacation or illness, the university may remove it.Harvard UniversityWith as many as 12 pet-friendly apartments, Harvard is a very pet-friendly university. It allows students to have fish in a tank of no more than 50 gallons, except for Harvard’s Cronkhite Graduate Center.In Harvard’s pet-friendly apartments, you’re allowed: one cat or one dog, which can’t be over 40 pounds when fully grown. At most, two pet birds.University of British Columbia Students can take advantage of the university’s B.A.R. K program, which uses the calming power of therapy dogs to help them.B.A.R. K started at the University of British Columbia, after an assistant professor called Dr. John-Tyler Binfet noticed that he couldn’t walk across campus without students running over to play with his dog, Frances. The students told him they were homesick and missed their pets, which encouraged Binfet to establish B.A.R. K as a way of fighting their loneliness.University of OxfordThe University of Oxford is famous for its resident pets, who happily wander around college grounds. Many Oxford colleges have their own tortoise and take part in the annual Corpus Christi tortoise race.Although you are not allowed to keep your own pet as a student, several Oxford colleges hold dog petting and walking therapy sessions.1.What is one of the rules for keeping pets at the University of Illinois?A.Pet keepers should pay a monthly US$ 30 pet fee which will be returned.B.Pets can’t be left alone in the apartments due to vacation or illness.C.Students have to keep fish in a fish tank of no more than 20 gallons.D.The cat or dog can’t be over 40 pounds when fully grown.2.Why did Dr. John-Tyler Binfet start B.A.R.

B.University of Oxford.C.University of Illinois. D.University of British Columbia.BA survey by the American Psychological Association shows that one in ten adults reads online news at least once an hour. A lot has been written about the mental health influence from news addiction, and in particular from reading negative reports. Just like junk food, “junk” news can be bad for our health.In recent years, things have been getting increasingly more negative. A study of the content of New Zealand’s largest newspaper showed that while in 1973 the average number of stories about death on the front page was 0.75, by 2013 it was 4.1(and no, there weren’t five times more people dying).What’s more, online news, and the stories we read on mobile phones in particular, tend to be even more negative than print. A 2019 study of 50 U.S. newspapers showed that mobile versions of newspapers report three times more stories about disasters and accidents than paper ones.Such negative reports lead people to believe that things are worse than they really are. They can lead to stress, worry and lower spirits.Experiments also suggest that loneliness and poor relationships have been connected with reading negative reports. After reading negative reports, people are less likely to help others. Even worse, when we check news on smart phones, we may “phub” our loved ones, which leads to lower relationship satisfaction.Negative reports attract our attention far more than positive ones. That’s a global happening. I hope, however, that if we realize that negative news is spoiling our moods, we might all be more willing to change. 4.Why is “junk food” mentioned in the first paragraph?A.To entertain readers.B.To introduce the topic.C.To make an advertisement.D.To keep readers away from it.5.What can we learn about the study in Paragraph 2?A.The death rate in New Zealand is very high.B.Print newspapers have become less popular.C.Stories about death have become less popular.D.Negative reporting has been increasing over years. 6.What may negative reports lead people to do?A.Live a hopeful life.B.Become more careful.C.Become less likely to help others.D.Pay more attention to their physical health.7.What does the underlined word “phub” in Paragraph 5 mean?A.Ignore B.Hate C.Laugh at D.Care about8.Which of the following can be the best title for the text?A.A Survey on News Reading Habits B.Negative Effects of Mobile PhonesC.Is Online News Better Than Print?D.Is Junk News a Danger to Health?CThere was once a boy called Mario who loved to have lots of friends at school. However, he wasn’t sure whether or not his classmates were his true friends, so he asked his grandpa. The old man answered, “I have just exactly what you need; it’s in the attic (阁楼). Wait here for a minute.”Grandpa left, soon returning as though carrying something in his hand, but Mario could see nothing there. “Take it. It’s a very special chair. Because it’s invisible (无形的) it’s rather difficult to sit on, but if you take it to school and you manage to sit on it, you’ll be able to tell who your true friends are.”Mario took the strange invisible chair and went to school. At break time he asked everyone to form a circle, and he put himself in the middle, with his chair. “Nobody move. You’re about to see something amazing,” Mario said.Then Mario tried sitting on the chair. He missed and fell straight onto his backside. Everyone had a pretty good laugh. Mario wouldn’t be beaten. He kept trying to sit on the magic chair, and kept falling to theground... until, suddenly, he tried again and didn’t fall. This time he sat, hovering (悬停) in mid-air.Looking around, Mario saw George, Lucas, and Diana — three of his best friends — holding him up, so he wouldn’t fall. At the same time, many others he had thought of as friends were doing nothing but make fun of him, enjoying each and every fall.Leaving with his three friends, Mario explained to them how his grandpa had so cleverly thought of such a good idea. Now he knows that those who take joy in our misfortunes (不幸) when we are in difficulty are not our true friends.9.What did Mario’s grandpa take from the attic?A.An invisible chair.B.An old chair.C.A real chair.D.Nothing.10.Why did Mario’s grandpa give him the invisible chair?A.To see whether Mario could sit on it. B.To test who were Mario’s true friends.C.To let Mario have fun with his classmates.D.To test whether Mario was popular at school. 11.How was Mario able to hover in mid-air?A.He saw the invisible chair suddenly. B.He managed to sit on the chair finally.C.His friends held him up with their hands. D.His classmates gave him a chair to sit on.12.What does the story tell us?A.Never laugh at our friends. B.True friends can help us do magic.C.True friends are those who care for us. D.Having too many good friends isn’t a good thing.DSure, it’s good to get along well with your teacher because it makes the time you spend in the classroom more pleasant.And yes, it’s good to get along well with your teacher because, in general, it’s smart to learn how to get along well with the different types of people you’ll meet throughout your life.In fact, kids who get along well with their teachers not only learn more, but they’re more comfortable with asking questions and getting extra help. This makes it easier for them to understand new materials and makes them do their best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school issues (问题).Here is a question:What if you don’t get along with your teachers? In fact, teachers want to get along well with you and enjoy seeing you learn. But teachers and students sometimes have personality clashes (个性冲突), which can happen between any two people.

I went climbing with a millennial(千禧一代).She is younger, fitter, braver and more energetic. I am good at getting discouraged, having a rest and giving advice from the sidelines. She will cling(附着于)on to a wall like a small monkey trying to escape certain death, while I will get near the top, realize how high that is and lose my nerve. Together we could make an impressive(感人的;令人钦佩的) team, me at the bottom of the wall, going, "That's great, try using your feet one by one. Oh...What did you do that for?" And her going, "Shall we try that again so we've actually done it? Do you think we should have warmed up first?"Climbing muscles, being the same as regular muscles, are use-it-or-lose-it. I climbed more often before I did the crazy running activity and used to think of the green runs at my local center as being for children, or for a warm-up. Now I find them extremely hard, and the purple is my top-of-the-tree, when in fact they are both for beginners, really. I suspect the millennial of avoiding the blue-with-red-spots just so as to not show me up.It wasn't her first time climbing, but she wasn't registered at the center, so she had to go through a process that sounds threatening: watching a video and answering questions on it (the answers are always "I am responsible for my own safety in the center" and Holds may spin"). In an older person-me, for instance-any activity that starts with a reflection on your own death is a little low-energy, whereas she seemed quite excited by it.We both laughed at each other's clothing: she accused me of having, a pink T-shirt which seemed too lovely for me, while she was dressed to be a labourer. The moral is that you can basically wear anything while you climb. It's not like running, where the ill-dressed are chased from the area by a thousand eyes.1. We learn from Paragraph 1 that the author and the millennial .A.know each other very well B.try to learn how to escape deathC.form a sharp contrast D.make a team that beats others2. By “climbing muscles, being the same as regular muscles, are use-it-or-lose-it” the author means______.A.climbing does good to musclesB.climbing needs practicing regularlyC.climbing muscles are as useful as other musclesD.climbing muscles won’t be lost even if not used3. The question the millennial was required to answer were admitted to .A.let the climbers realize the climbing might be dangerousB.give the climbers another approach to think of deathC.warn the climbers against loss of energy in the processD.remind the climbers of the importance of registration4. According to the passage, which of the following statements is true?A.Climbers need to wear special clothes.B.Ill-dressed runners stand out improperly.C.Climbers need to get a certificate before climbing.D.The author and millennial like making fun of others.3. In the animal kingdom, weakness can bring about aggression in other animals. This sometimes happens with humans also. But I have found that my weakness brings out the kindness in people. I see it every day when people hold doors for me, pour cream into my coffee, or help me to put on my coat. And I have discovered that it makes them happy.From my wheelchair experience, I see the best in people, but sometimes I feel sad because those who appear independent miss the kindness I see daily. They don’t get to see this soft side of others. Often, we try every way possible to avoid showing our weakness, which includes a lot of pretending. But only when we stop pretending we're brave or strong do we allow people to show the kindness that’s in them.Last month, when I was driving home on a busy highway, I began to feel unwell and drove more slowly than usual. People behind me began to get impatient and angry, with some speeding up alongside me, horning (按喇叭)or even shouting at me. At the moment I decided to do something I had never done in twenty-four years of driving. I put on the car flashlights and drove on at a really low speed.No more angry shouts and no more horns!When I put on my flashlights, I was saying to other drivers, “I have a problem here. I am weak and doing the best I can. And everyone understood. Several times, I saw drivers who wanted to pass. They couldn’t get around me because of the stream of passing traffic. But instead of getting impatient and angry, they waited, knowing the driver in front of them was in some way weak. Sometimes situations call for us to act strong and brave even when we don’t feel that way. But those are few and far between. More often, it would be better if we don’t, pretend we feel strong when we feel weak or pretend that we are brave when we are scared.1. People will feel happy, according to the author's findings, when __________.A.they offer their help to others B.they receive others’ helpC.they feel others’ kindness to them D.they show their weakness to other people 2. Why does the author feel sad sometimes?A.Because he has a soft heart, showing sympathy to others.B.Because he is disabled and relies much on others.C.Because some people pretend to be kind, but in fact they are not.D.Because some people fail to see the kindness in others.3. What did the other drivers do when they saw the flashlights?A.They sped up to pass because they didn’t want to wait.B.They stopped their cars to offer help.C.丁hey put on their flashlights too.D.They waited with patience.4. In this passage, the author advises us to _________.A.be independent of others and handle problems by ourselvesB.accept help from others for everythingC.admit our weaknessD.show our bravery4. Water is a necessity of life. Rain, especially, helps plants grow and stay green. But too much rain, especially in cities, can lead to flooding. That can cause waste water systems to overflow and send pollutants into rivers and other waterways. To fight the problem, several cities in the United States are starting programs like rooftop gardens.A team at the University of the District of Columbia in the nation's capital has created a garden on the top of one school building. The garden holds many kinds of plants to help absorb rainwater and grow food at the same time. Architect David Bell has designed five "green roofs" for the university. He says he is excited about the project because "it meant doing something more than just dealing with storm water management. It took advantage of a resource above the city and these flat roofs that aren't doing anything really became something that was about urban agriculture. " Rainwater is collected in large containers and sent through a system that waters the rooftop garden. The roof is filled with green life that appeals to insects.In cities, “you don't have that many spaces to choose from and so rooftops are just (unused) space," says Caitlin Arlotta. She is a student in the school's Urban Agriculture program. The project is part of a research program to see which plants do well on rooftops. The researchers are looking at plants including strawberries, tomatoes and sweet potatoes. The university also has other green spaces. "We also have our own farm experiments," A rlotta said. “ Within each of those growing systems, we want to be able to tell people which sorts of these crops grow the best. "Sandy Farber Bandier helps run UDC's Master Gardener program. It seeks to improve cities and make them beautiful by training people to become Master Gardeners. She says she's been surprised by the garden's output. ”My biggest surprise was that we produced 4, 250 pounds of produce the first year and was able to spread that to people in need. " She also likes being able to show people who live in D. C. and others beyond the nation's capital what and how food can be grown on a rooftop. “This is the future for food. You grow it here, you prepare it in a commercial kitchen, you distribute through farmers markets,food trucks, and then you recycle. "1. What do we know about the rooftop gardens?A.Rooftop gardens are very common in average neighborhoods.B.There are many sorts of plants there which help take in rainwater.C.They're playing an important role in the city's food supply.D.Rooftop gardens are no more than containers to collect rainwater.2. What can we infer from Paragraph 3?A.Rooftops can offer enough space to plant crops.B.Many plants like strawberries can grow well on rooftops.C.Some univercity students are participating in the Urban Agriculture program.D.The plants in rooftop gardens are attractive to many insects.3. How does Sandy Farber Bandier feel about the future of rooftop gardens?A.Confident.B.Doubtful.C.Worried.D.Ambiguous.4. What is the best title for the text?A.Rainwater Necessity for Plant LifeB.Green Roofs-The Future of Urban AgricultureC.The United States' Agriculture ProgramD.Rooftop Gardens-Food Paradise5. Last week the electricity in my flat went out. 1 My typical evening is spent watching TV and scrolling (滚动) through social media. Tonight this wasn’t possible. My roommate and I weren’t prepared with candles and matches. We just rely on electricity.So for me it was an early night, 2 That night, losing our electricity felt like losing a basic necessity, as basic as running water. But really, electricity is a luxury that we’ve grown to take for granted. I use electricity all the time, even when it’s not really necessary.3 And as I’m writing this, I have my lights on, even in the middle of the day when I don’t really need them.4 It contributes to global warming. It is harming our environment and we need to do what we can to stop it. Not only that, but if we continue to use the same large amount of energy, we will soon run out of it.How would we survive in a world without electricity? Our daily lives go around it. We wouldn’t be able to function. 5 So, shouldn’t we start preparing for it now? Cutting down on our use of electricity would save energy resources so that they could last for longer. And if everyone does it, we can make a big difference.6. On a raining day, I wen t to buy some aspirin. Upon entering a lady’s drugstore, I _________ that there was a keyboard on a music stand, leaning _________ the wall. Being a piano music lover and _________, I asked if the woman played. She nodded and added that she had been _________ lessons at age 60!
