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.

The kindness from other cyclists.CHundreds of thousands of lives were saved in 2017 alone because of the improvement of the environment, according to a new research. 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?。

A newspaper reporter interviewed him why he was able to be so much more creative than the average person. What set him so far apart from others?He responded that it all came from an experience with his mother that occurred when he was about two years old. He had been trying to remove a bottle of milk from the refrigerator when he dropped the slippery bottle, spilling its contents all over the kitchen floor — a real sea of milk!When his mother came into the kitchen, instead of shouting at him, giving him a lecture or punishing him, she said, “Robert, what a great and wonderful mess you have made! I ha ve rarely seen such a huge pool of milk. Well, the damage has already been done. Would you like to get down and play in the milk for a few minutes before we clean it up?”Indeed, the boy did. After a few minutes, his mother said, “You know, Robert, wheneve r you make a mess like this, eventually you have to clean it up and restore everything to its proper order. How would you like to do that? We could use a sponge (海绵)，a towel or a mop. Which do you prefer?” He chose the sponge and together they cleaned up t he spilled milk.His mother then said, “You know, what we have here is a failed experiment in how to effectively carry a big milk bottle with two tiny hands. Let’s go out in the back yard and fill the bottle with water and see if you can find a way to carry it without dropping it.” The little boy learned that if he grasped the bottle at the top near the lip with both hands, he could make it. What a wonderful lesson!This famous scientist then said that it was at that moment that he knew he didn’t need t o be afraid to make mistakes.8.

The starting and finishing points are the same place.BMy father was the gentlest, most loving and caring dad in the world----until we had an argument. During those moments, my words surely never reached his “open mind” because his ears were closed. There was no point trying to argue with my dad. He always had the last word.I could never win.When my father refused to understand that I needed the privacy of a phone in my room, my frustration turned to tears. He ended our “discussion”, leaving me silently defeated and miserable. So when he refused to change his idea about letting me go on my class trip to Montreal, I could do nothing but race from his room in despair.With the hope that his eyes would be more open than his ears, I began to write a note that began with “Dear Daddy” and ended with how much I respected his opinion, how much I hated to fight with him and how much I valued our relationship and, above all, how much I loved him.I folded my note into an envelope, slid it under the door of his bedroom and raced back to my own room. It was only minutes before I heard a knock at my door. When I saw the look on my father’s face, I knew that my note had melted his temper and touched his he art.The victory of winning my dad’s permission to go to Montreal was sweet. But even sweeter was the discovery of a strategy that enabled me to have an argument with my dad that didn’t end in tears, but instead with a hug. My “Dear Daddy” notes became a follow-up to many of our arguments.Years later, one of my favorite stories was the “Dear Daddy” notes. It always made me smile to remember some of our most passionate arguments and how my dad would become sopig-headed, until he read my notes.18. What did the author think about her father during an argument?A. GentleB. StubbornC. AggressiveD. Open-minded19. The “Dear Daddy” note is a good way to ______.A. avoid meeting her father suddenlyB. stop the argument in a funny wayC. deliver her message more quicklyD. persuade her father into supporting her20. The author’s father impressed her most with his ______.A. last wordB. generous loveC. bad temperD. pig-headed decisionCBig data of the human face can make a difference. Technology is rapidly catching up with the human ability to read faces. Apple’s iphone X has already used face recognition to unlock the home screen. Face recognition is becoming increasingly common in China, where it has been equipped at ATM and KFC restaurants. It is also used by shop owners to catch shoplifters.Some universities are using face recognition technology as a means to keep track of the students’ attendance in the classrooms. Students stand in front of a screen when they walk into lecture halls. Photos taken at the screen are matched with those logged in the university’s database. It’s believed that the system is highly accurate（精确的）because it can identify students even if they change their hair or wear makeup. Students have joked that face recognition is so strict that they don’t dare to skip classes anymore. The traditional way of taking attendance is through a roll call. The new system helps to improve efficiency（效率）.Face recognition technology has already been used in different fields in Chin A. Police have set up face recognition scanners at busy crossroads to catch jaywalkers, whose photos will be shown on the digital screen as a warning. In the hotels of Wuzhen attractions, facescanner-equipped gates identify tourists staying in its hotels. The data collected will then serve as Entry Pass through the town’s various attractions. Tourists do not have to pay extra entrance fee. Face recognition has also been in business use in Chin A. Alipay, for example, is using its face recognition technology to help customers at a Hangzhou KFC branch order food: The camera in the KFC will check customers’ face against the ID card photos linked to their Alipay accounts.Face recognition is expected to be used in all sorts of fields. It is going to become part of your life if it isn’t already.（以下是A 种题型）21.
