How can you spend the time you have left to best effect? Read these thoughts from new graduates to get some pointers. Cao A'min, 18 Xuanhua No 1 High School, Hebei Study: Keeping pace with teachers is a good way to study. Teachers are experienced and their plans are systematic . But remember to work in a way that suits you. It's also important to learn from past mistakes. Keep a notebook to make a record of the mistakes you make - it'll help you avoid making the same ones later. Zhang Zilu, 17 Xinyu No 1 High School, Jiangxi Friendship: This time of life may be hard, but you're not alone. You may be busy studying, but you can show you care by calling your friends or sending a short message. Don't let your friendships die. Some boys and girls in my class were in love, but I'd advise against a relationship at this stage. Zhan Yu, 17 Huanggang High School, Hubei Health: It's as important to live well as it is to study well, I think. I went to bed no later than 11:30 pm. It put me in the right mood for the next day. I didn't follow a special diet , but I did make sure I ate a nutritious breakfast each day. Ju Shuntian, 18 Yantai Economic and Technological Development Zone Senior High School, Shandong Relaxation: The person who plays well, studies well. Having a lot of schoolwork doesn't mean having to give up on every other activity. I played basketball or took a walk to relax when I felt tired. Time out is not a waste of time but helps you study more efficiently . Zhang Qingzhou, 17 Dongtai High School, Jiangsu Options: Besides taking the big exam, you have other choices for college.

Since the 1970s, scientists have been searching for ways to link the brain with computers.Brain-computer interface(BCI) technology could help people with disabilities send commands to machines. Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person's thoughts. In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand.He could even talk as he watched the vehicle and guided it with his thoughts. "Our brain has billions of nerve cells.These send signals through the spinal cord to the muscles to give us the ability to move.But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says."Our system allows disabled people to communicate with external world and also to control devices." The researchers designed a special cap for the user.This head cover picks up the signals from the scalp and sends them to a computer.The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path.They help the computer react to commands from the brain. Prof.Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands."The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices.One example is this wheelchair." He says his team has set two goals.One is testing with real patients, so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can use the technology over long periods of time. Which of the following would be the best title for the text? A) Switzerland, the BCI Research Center B) New Findings About How the Human Brain Works C) BCI Could Mean More Freedom for the Disabled D) Robotic Vehicles Could Help to Cure Brain Injuries

Ques: Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better. In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully. Sounds is measured in units called decibels . At a level of 140 decibels people feel pain in their ears. Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well. There is a saying that it is so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems. Noise adds more tension to a society that has already faced enough stress. When sound is turned into noise, _ . A) people grow worse and worse B) it makes us forget all the past C) people don't know what to do with everyday life D) it will be a kind of pollution to people

Question: Hurricane Babette reached the northeastern United States today and caused death and destruction everywhere. The killer storm carried winds of 135 miles per hour. The high winds and heavy rains, together with the force of the Atlantic Ocean, created extremely dangerous waves. It is not yet known how many people died or were hurt in this storm, but it is said that the numbers will be very high. The damage to homes, business and crops will run into billions of dollars. Now that the storm is over, the long, slow rebuilding will begin. With the arrival of the tornado season, the National Weather Service is again telling people how to protect themselves from these deadly storms. The winds from tornadoes are the most violent winds on earth. They can blow up to 400 miles per hour. A tornado looks like a funnel . It is also very loud. It may sound like a train coming at you. In fact, the winds from a tornado can pick up a train and throw it around. If a tornado is seen in your area, it is very important that you protect yourself. A basement is the safest place to go. Try to wait under a table in the basement. If your building does not have a basement, stay on the ground floor but lie flat under a bed or table. Stay away from windows. If you are outside or in your car, try to find a narrow place to lie down in. As the area tries to deal with the worst flood of the century, there are many heartwarming stories of people helping other people. From all over the world people have sent food and clothes to help the thousands who have had to leave their homes. Many volunteers have come to help to make sandbags and use them to build walls against the overflowing river. While the result of this disaster will be terrible for many, it is beautiful to see people coming together to help others and save lives, and property . We can learn from the passages that _ . A) Hurricane Babette damaged the northwestern coast of US B) when there's flooding, sandbags can be made and used to build wall C) the National Weather Service often takes measures to protect the local people D) people are often reminded of how to protect themselves from snowstorm
