Pen, pencil, eraser, ruler, and dont forget a bottle of water! According to a study at the British Psychological( 心理學(xué)的) Society Annual Conference held in London, students who bring water into exams may improve their grades by up to 10 percent. Scientists at the University of East London and the University of Westminster, UK, did a study on 447 students. The students were studying for different degrees(學(xué)歷) at the University of East London. Only 25 percent of them entered the exam hall with something to drink. Scientists then compared their exam results with their normal schoolwork grades. They found that all those who had brought drinks with them got better grades by between 2 and 10 percent. It is unclear why drinking water improves exam results. But scientists say having enough water in our bodies and not feeling thirsty could have a helpful effect on our brains. Drinking water may also cut down on anxiety(焦慮), which has a bad effect on exam performances, according to Chris Pawson, PhD, of the University of East London. Whatever the explanation, it is clear that students should try hard to stay hydrated(含水的) with water during exams, he said. So next time, when you are going to have a big exam, try bringing a bottle of water with you. Who knowsit may help you pass the exam!21. How much may the students improve their grades most if they bring water into exams?A. By 2%.B. By 8%.C. By 10%.D. By 25%.22. How many students in the study got better grades?A.

Newspaper.B Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that arent very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Lets discover friction! WHAT YOULL NEED: Soap Water Your hands! WHAT TO DO: Make sure your hands are dirty. Rub your hands together until you feel the heat of your hands. Now, use soap and water to get your hands very slippery(滑的). Try to make friction happen while your hands are slippery. Please write down what has happened. LETS TALK! Friction is an energy that happens when two things tub together. When friction happens, it makes heat! When your hands are slippery, they wont make very much friction and your hands wont get so hot. DID YOU KNOW? Friction happens when you stop your fast running bike. Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didnt know it. Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not hot, touch the tires(輪胎) of the car before and after a short drive to see how much warmer they get from friction.26.

It explains the world and makes our lives easier with technology. One of the most exciting fields in science is artificial intelligence (人工智能,AI). This is an area where scientists are working on creating machines that think like humans. However, one of the most famous scientists has a very dark warning for us about this type of technology. The development of full artificial intelligence could spell the end of the human race, said Professor Stephen Hawking to the BBC. Hawking is a well-known British physicist and author of bestselling science book A Brief History of Time. This warning came after commenting(評論) the technology he uses to speak with. As Hawking has got a serious disease called ALS, he needs an AI computer to communicate. The computer learns how Hawking thinks and suggests the words he may want to use next. This is a basic type of AI, which is very useful, yet Hawking fears the possibility of creating technology that can match or surpass human intelligence. And its easy to imagine how terrible things may be. Many TV shows and films show big, killer machines that are far cleverer than us. Humans, who are limited(限制) by slow biological evolution(進化), couldnt compete, said Hawking. But not every scientist is pessimistic(悲觀的) about AI technology. I believe we will be in control of the technology for a long time, said Rollo Carpenter, creator of Cleverbot in the UK, which is a software program that remembers past conversations, The advantages of it to solve many of the world problems will be realized. In what direction do you think AI is heading? Should we be hopeful or fearful?31. Which of the following is TRUE about AI?A. It makes our lives easier.B. The technology is not very popular now.C.

This made it easier to carry heavy things and to travel long distances. For hundreds of years after that there were few inventions that had as much effect as the wheel.Then in the early 1800s the world started to change. There was little unknown land left in the world. People didnt have to explore much any more. They began to work instead to make life better. In the second half of the 19th century many great inventions were made. Among them were the camera, the light and the radio. These all became a big part of our life today. The first part of the 20th century saw more great inventions. Movies with sound in 1926. This was also a time when a new material(材料) was first made. Nylon came out in 1935. It changed the kind of clothes people wear. The middle part of the 20th century brought new ways to help people get over diseases. They made people healthier and let them live longer lives. By the 1960s most people had a very good life. Of course new inventions continued to be made. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space. In 1969 man took his biggest step away from earth. Americans first walked on the moon. This is certainly just a beginning thought. New inventions will some day help us to do things we have never dreamed of.61. What could the first great invention help people do at that time? 62. How long did it take people to invent Nylon after movies with sound were made? 63. When did most people have a very good life according to the passage? 64.
