Here is a page from a magazine called Future. Read the following information about things that may happen in twenty years.

    Cars will run on solar power (太阳能) and will be much cleaner and safer. For example, if you are too close to another car or if you are driving dangerously, your car will slow down or stop by itself.

    New cities will have to be built in the sea. Some cities on water will have two levels(层). People will live on the upper level, the lower level will be used for traffic, shops and factories.

    Biotechnology(生物技术) will make food better and healthier. Plants without insects or illnesses(病虫害) will be developed. The taste of fruit and vegetables will be better and food will be kept longer.

    Many new ways to cure(治愈) illnesses will be found. People will use products of genetic engineering (基因产品) to cure more illnesses. However, some new illnesses will appear.

    A survey of young people around the world looked at their ideas of today's teenagers．It shows how different they are to those of their parents and grandparents．The survey wanted to try and understand the next generation （ 一 代 人 ） of adults better and these are some of the results．They show that there are many more （A） similarities between young people around the world than differences．

   ①   

    Gap years （间隔年） between school and university are becoming more and more common．Today's teenagers want to travel to different countries and experience different cultures．They regard this as an important part of their character development．

   ②   

    For most teenagers，family and friends are the most important side of life．According to the survey，60 percent of British young people said their relationship with their family was of the highest importance to （B） them ．

   ③   

    75percent of teenagers in Western Europe expect to have enough money to live when they are adults．They are a happy generation．Eight out of ten believe they will have a good profession with a job they enjoy．They also expect that they will be happy and healthy．

   ④   

    Young people now are hungry  for all kinds of information on mass media.57percent of teenagers in the UK read at least one magazine every week，which is one of the highest totals in the world．

    When you watch TV and play video games you make global warming(全球变暖) worse! To make electricity, fossil fuels(矿物燃料) are burned in big factories. But burning fossil fuels also makes greenhouse gases. This means that every time you use electricity you help make global warming worse!

    Cars are also making global warming worse. They burn fossil fuels in their engines, and send lots of greenhouse gases into the air.

    So what can we do to stop global warming?

    Try to use less electricity. First, turn off lights, your television, and your computer when you stop using them，You could also try to watch less TV. But you may find it hard to do these! Second, plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide(二氧化碳) out of the air when they grow. Last, don't throw away your rubbish, but try to recycle it. Because if rubbish is not recycled, it rots(腐烂) and makes a greenhouse gas called methane(甲烷). So try to recycle cans, bottles, plastic bags and newspapers. It'll make you feel great! And it'll help the Earth.

    Some people claim they" never forget a face". But what does that saying mean? Is there really no limit to the number of faces a person can remember? A new study at the University of York in England has found that, on average, people can remember as many as 5,000 faces.

    The study is the first time that scientists have been able to put a number to the abilities of humans to recognize faces. The research team tested people on how many faces they could remember from their personal lives and in the media. They also tested them to see how many famous faces they recognized. Rob Jenkins works in the psychology department at the University of York. He said the researchers' study centered on the number of faces people actually know. He said the researchers were not able to discover whether there is a limit on how many faces the brain can handle.

    In the study, people spent one hour writing down as many faces from their personal lives as possible. At first, they found it easy to come up with many faces. But by the end of the hour, they found it harder to think of new ones. Their change in speed let the researchers estimate when they would have run out of faces completely.

    The results showed that these people knew between 1,000 and 10,000 faces. Jenkins explained that some people may have a natural ability for remembering faces." There are differences in how much attention people pay to faces and how well they process the information," he said. Jenkins also said it could be because of different social environments. Some people may have grown up in more populated places. Therefore, they may have had more social contact throughout their lives.

    The people in the study included 25 men and women between 18 and 61 years old. Researchers think age may be an interesting area for further research. "It would be interesting to see whether there is a peak age for the number of faces we know", Jenkins said. He said it is possible that we gather more faces throughout our lifetime. But, he added, there also may be an age at which we start to find it harder to remember all of those faces.

    The study suggests our facial recognition abilities enable us to deal with the many different faces we see on the screens, as well as those we know, like family and friends. Today, facial recognition technology is used in many ways, including by law enforcement agencies to prevent crime and violence. Governments use it to keep secret areas secure and, in extreme cases, control populations. .Even Facebook uses facial recognition. For example, when you "tag" or name a friend, Facebook technology may recognize the person's face from a different picture you had shared before.
