How to Improve Your Memory
Man still has a lot to learn about the most powerful and complex (复杂的) part of his body—the brain.It may be surprising to learn that it isn’t age that makes you lose your memory. The reason could be that you have a “lazy” memory, not an old one. Like your body, your memory improves with exercise. Once given plenty of exercise, the brain keeps its power. Before discussing how to improve the memory, let’s look at how the brain works. There are two sides to the brain, the left and the right. The right side deals with senses (what we see, hear, feel and smell). It’s the creative and imaginative side. The left side is related to logical (逻辑的) thinking, which analyzes (分析) information and puts it in order.Some recent research suggests that we remember everything that happens to us. The problem most of us have is recalling (回忆) events. Most forgetting takes place immediately after learning. An hour after learning something new, more than 50% has been forgotten. After a month, 80% has been forgotten, and so on.
This research is very important. It shows if you review new material you have learnt, you remember much more. So it’s of the greatest importance to review newly learned material often, and have breaks often. You best remember what you learn at the beginning of a learning period and at the point where we stop. After the break, review what was learned before the break and then continue learning the new material. These breaks should happen every 20 or 45 minutes.
Other experiments have shown the brain needs time to take in what has been learned. The time necessary for this is 5 to 10 minutes. After the break, the memory will have taken in what it has just learned, and more will be remembered. During this period it is important to exercise the right side of the brain, because the left side is used during the learning period. Therefore you should relax. Listening to music, breathing in fresh air, and looking at a picture are all ways of using the other side of the brain. So when you are studying alone, make a plan which shows when to have breaks and to review newly learned material immediately before you begin studying again. If you do in this way, your memory will improve.
1.To fight forgetting better, we’re advised to ______.
A.break down materials into small prices
B.use two sides of the brain together
C.make proper use of our senses
D.go over what was learned often
2.During the learning process the brain needs breaks to ______.
A.use the right side of the brain
B.review newly learnt materials
C.take in what has been learnt
D.relax the left side of the brain
3.What can we learn from the passage?
A.Old age makes people lose their memory and forget the past.
B.People can remember 20% an hour after learning something new.
C.Listening to music is the best way to use the left side of the brain.
D.Memory works best at the beginning and the end of a learning period.

Are you still worried about how to get your phone charged(充电)? Now, a 19yearold teenager can help you to solve this problem. He has invented a phone charger which uses energy from your own body to charge your phone.
Hand Energy, the wonderful invention of the inventor Michael Vaga, allows you to charge your phone simply by shaking your hand, which starts the charger's gyroscope(陀螺仪) to produce electricity. And the electricity can then either be stored or used to charge a mobile immediately(立即).
He said, “With each rotation(旋转) of your hand, the gyroscope's speed increases quickly and produces more power. The average(平均的) speed of the gyroscope is about 5，000 rounds per minute. With this small charger, your physical energy can be turned into electrical energy and this means you can charge your phone. ”
Hand Energy can help you produce endless electricity. You can use it everywhere you want. It is especially useful for people who have to spend a long time in the wild. What's more, it's friendly to the environment and helps you to exercise your wrists. It takes between 40 minutes and one hour to fully charge the batteries(电池) in Hand Energy.
The invention took Vaga a year to develop. Now, the inventor from Minsk, Belarus, is ready to put it into production and send out the creative convenient chargers.
1.The energy of the new charger comes from ________.
A. the sun B. your body C. the batteries D. your phone
2.If we want to produce energy with the charger, we should ________.
A. shake our hands B. move quickly
C. go to the wild D. charge our phone
3.Who will be the most interested in the invention?
A. The teachers. B. The medical workers.
C. The drivers. D. The field workers.
4.It is not clear whether ________ or not, according to the passage.
A. the more you shake, the more power it produces
B. the charger helps to protect the environment
C. we can buy the charger online in China
D. it will produce endless electricity
5.Which of the following could be the best title of the passage?
A. A wonderful invention B. A great inventor
