ASun bears（马来熊）are the smallest of the world’s eight bears species（物种）. They have a black coat and a white or golden color on their bodies. Their homes are in the tropical（热带雨林）of Southeast Asia. They live in trees and eat both plants and animals. They can grow to be 1.4 meters in height and 65 kilograms in weight. They usually live alone and are happy to spend most of their time by themselves.Scientists studied sun bears in the Bornean Sun Bear Conservation Center. They found that although sun bears live alone, they have developed a surprising social skill. They can copy (模仿) other sun bear’s facial expression (面部表情) as a form of communication. They can even copy exact muscular (肌肉的) movements that other sun bears make- such as making a face.The ability to copy facial expressions is found in humans, gorilla’s (大猩猩), some monkeys and some other animals. But until now, only humans and gorillas have the ability to exactly copy facial expressions. However, scientists found that sun bears can copy facial expression as well as humans and gorillas. This surprised them because sun bears are alone and they have no close relationship with human beings.Although they live alone in the wild, the sun bears in the study often played gently with each other. Sometimes they played with faster actions as hitting and biting. Scientists are still not sure what messages the sun bears were sending to one another.( )1. According to the passage, where do sun bears usually live?A. In caves.B. In trees.C. By the river.D. On the ice. ( )2.

Which of the following might be the best title for the passage?A. A warm home on the earthB. A brave animal in the forestC. A new friend of human beingsD. A surprising skill of sun bearsBTechnology is developing fast and it has become an important part of our life. Then what will the world be like in the future?3-D food will be both delicious and nutritious(有营养的). We can use 3-D printers to print some basic materials. ①And we can go further. Scientists believe that we just need to turn on a printer in the kitchen and then we can enjoy our favorite food whenever we like.②5G network will allow many more people to get information.Big companies like China Mobile and China Unicom will start to offer 5G. It is said that promises download speeds 10 to 20 times faster than 4G. For example, we can download a film within just 1 second. But with a 4G network, it takes a few minutes. There will be much bandwidth (带宽) and we can get unlimited (无限的) information.Underwater cities will provide more space. The earth is becoming more and more crowded. We may turn to underwater homes, which will be built as low as 15 of the sea can be used to provide power for the homes.③For us common people on the earth, the dream of travelling around space will come true. In the coming years, spacecraft will be as popular as buses, trains and planes. We can leave our home and enter space to take an adventure (冒险). And even we will get used to living there.A robot will be a part of life. Robots can do many of the same things as we humans do like driving cars. But they will be used in other areas as well.

We can recycle some of our rubbish. Recycling means that the rubbish will be made into something that can be used again.Recycling helps Earth. And it saves space in rubbish dumps. Half of everything that we put into landfills could be recycled instead. In fact, most things made of paper, metal, glass and plastic can be recycled.Paper can be broken into small pieces and made into new paper. Steel and aluminum cans （金属雄）can be melted down（熔化）and made into new cans. The same is true of glass bottles. This can be done over and over again. Recycling doesn't take as much energy as making these things the first time. So we can use less of Earth's fuel resources.Plastic can be melted down, too. Then it can be formed into park benches, playgrounds and so on. Some people call plastic the "wood" of the future. Things made of plastic will last about 400 years-even if they stay outside in the weather. No wood can do that!( )11. The underlined word "landfills" in Paragraph 2 probably means _____________.A.bench factoriesB. places for rubbishC. green mountainsD. recycling centers( )12.

Straws (吸管), toothbrushes, toys—all kinds of plastics are placed in landfills. There are 5 billion tons of plastic waste in the world. Landfills have a large part of it. By 2050, they could have 13 billion tons.Much of plastic rubbish finds its way into the ocean. Scientists say 165 million tons of plastic pieces are floating around out there. And most plastic won't disappear itself. It will remain in the ocean forever. Whales get caught in plastic fishing nets. Birds die because of eating plastic straws and bottle caps. It endangers ocean life. Plastic rubbish even ends up in the food we eat.Governments are realizing that recycling may not be enough. They are taking more actions. Though it is hard work, it is still a solvable problem. In Britain, people are not allowed to use plastic bags except in hospitals. Scotland and several coastal cities in the US stop people from using plastic straws as well. The US alone throws away some 500 million plastic straws a day. That's enough to circle the Earth twice. "Saying no to a plastic straw is an easy way to make a big difference," Diana Lofflin who started said. "'Do we really want to pass on to our children a world harmed by plastic?"People have found some tasty ways to reduce waste. A company in India made the first-ever spoon that people can eat. You don't have to eat the spoon. You can throw it away. It decomposes (分解) in just a few days. David Edwards, a scientist at Harvard University, designed an eatable bag which can protect the food or drink inside. It is a delicious replacement for plastic ones.( )17.According to the writer, birds die because they ________.A.eat bottle caps and strawsB.get caught in fishing netsC.feed on ocean animalsD.have the spoons in India( )18.The underlined word "endangers" in Paragraph 2 probably means ________.A.bringsB.losesC.harmsD.saves( )19.The purpose of the passage is mainly to ________.A.introduce some ways to recycle wasteB.tell readers about the problem with plasticspare air pollution and plastic pollutionD.describe how the US is reducing plastic waste( )20.From the passage, we can tell that the plastics problem ________.A.is too big for people to solveB.can be solved by recycling aloneC.can be solved, but it won't be easyD.will have to be solved by future scientistsGTexting while driving is against the law in 47 states.

For example, people might look at what others have, like expensive clothes or nice cars, and wish they could have the same. But the things that money can buy can’t bring happiness to a person for long.① But is that really true? Studies have found that money can, in fact, make people happier. ① Instead, it's giving money to others that makes people happy, ① It could be buying a present for a friend or a family member. ① It could he buying a homeless person food to eat. It could he giving money to a person in need. Just think about the last time you used your own money to do something for someone else. How did you feel? Whether it is a small or large amount of money. People feel happier when they give. This is because making someone else happy makes the giver happy, too.This idea of connecting your happiness to the happiness of others is described as a ubuntu in an African language. There is even a story about a man visiting Africa who asked some kids to race to a nearby tree. 'Me first child to touch the tree would get a sweet treat.

America and England had already fought two wars. Now, they were at peace. But one day a pig got hungry. And it nearly caused another war between the two countries.The pig was owned by a British man who lived on a small island. The island was just of the western part of North America. Both England and the US said the island was theirs. Across the island from the British man lived some American farmers. Everyone on the island got along peacefully. But the peace ended the day the British man's pig decided to eat some of an American farmer's potatoes.One of the American farmers shot and killed the pig. Then the pigs owner wanted $100 from the man who shot the animal. That was a lot of money, so the farmer refused to pay it. The British and Americans began to argue, and the situation got worse. The farmers asked the governor over the island at that time for help. He sent a group of soldiers to protect the farmers. The British answered by sending 2,000 soldiers. The British were on one side of the island, and the Americans were on the other. The problem that began with the pig was about to become, shooting war.When news of the problem reached Washington and London, both leaders were surprised. Neither country wanted another war.

They would stay there until the two countries could decide who owned the island. Then the others would have to leave.Twelve years went by. Neither side wanted to give up, the island, but they knew they had to do something. They asked the leader of Germany to help decide. After nearly a year of discussion, a decision was made.

The computer program looks for different kinds of answers or patterns in the data. Big data can have different kinds of information from many sources, such as information that comes from schools, social media sites, companies and governments. One set of data can have people's names and addresses. Another set can have what they like, where they go to school, and how much time they spend on the computerBig data can be used in many ways. The government uses it to understand how many people travel on buses or trains. This information is then used to make bus or train systems better. Some schools use big data to understand which children may need extra help in class. The teacher can then give certain students more help or support so those students can succeed in school. Companies use big data, too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream.Big data can be used for good reasons. Some hospitals use big data to predict if a baby who is bum too early will get sick. The hospital can then take extra steps to take care of that baby so he, she does not get sick. Big data can also be used for bad reasons. It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong.How can big data be used for good and bad things? It is because the computer programs used to look at big data and understand it are written by people. People think a certain way. Because they think a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people.( )33.
