Most people hope to have a memory which helps them succeed in study, work and life. Can memory be improved? Luckily, hundreds of studies in the past 50 years have already given us a definite answer.
A healthy lifestyle keeps your brain young and memory sharp. First of all, it is necessary to have a healthy diet. Eating more food rich in Vitamin B and Vitamin E, such as vegetables and lean meat, helps you have a better memory. Doing exercise can keep your brain alive, too. Proper exercise provides much needed oxygen for the brain. Running, riding a bike, swimming and even walking two or three times a week are helpful. Moreover, getting enough sleep is important. Only when your brain gets a good rest, can it work well. The healthier your lifestyle is, the better your memory will become, but do not expect a sudden change—it takes a long time to make a difference.
Memory skills help you remember things better. The following three are the most widely used. Chunking is a way of remembering a piece of information by cutting it into smaller ones. For example, to memorize a ten-digit telephone number 2127983630, you can divide the digits into three groups: first 212, then 798, and lastly 3630. This method is far more effective than remembering a string of 10 digits. Organization means organizing information into groups of the same kind. For example, trees, grass and flowers are plants; tigers, pandas, horses and cows are animals. Imagery is remembering newly learnt information by using your imagination and connecting it with something that you are familiar with.
However, memory skills will hardly work if you don't understand the information. What's more, only a regular review can make the memory last long. That is why students are always advised to go over what they have learnt after one day and then after three days, and then use it as regularly as possible.
Human brains are like muscles that need nutrients and exercise to become stronger. If you make a few lifestyle changes and try some memory skills, you can certainly improve your memory.

The Future Body Network
Are you tired of wires that spread all over your desk and make your tea pour onto your keyboard? If so, you may consider using devices（设备）that use technologies like Wi-Fi or Bluetooth. Neither of them sends information through wires. It sounds perfect, doesn't it? But this is not the end of the story.
Scientists are now trying to use the human body to do a similar job. They have come up with the idea of sending information over the small electric field on the surface of the skin. To do this, a transmitter（传送器）could be built into your pocket or a portable device like an MP3 player. This transmitter would then use your skin's electrical field to send information to a receiving device. Since this kind of transmission can only go as far as 20cm, the receiver would have to be close to some part of your body.
By using this body network, you wouldn't need a wire to link your MP3 player in your pocket to the headphones in your ears, or to send to your computer the pictures from a digital camera hanging around your neck. Moreover, you can exchange electronic cards or share music files with others by shaking hands, dancing cheek（脸颊）to cheek, or kissing each other.
Now, here comes a question. Why would anyone want to use their body as a network when Wi-Fi and Bluetooth already exist? The answer lies in the fact that with Wi-Fi or Bluetooth, it is hard to limit the signals only to your own use. In a busy place, you can never know who might steal your information. However, body networking is safer. It is hard for other people to pick up signals sent over the surface of your skin since this body network only has a limit of 20cm from your body. Thus, no one else can easily pick up and interpret your signals.
Moreover, the most important use of body networking in the future may well be communication within the body rather than just on its surface. Imagine having a number of small devices implanted under your skin and using them to control your own nervous system. In other words, imagine that you have a powerful in-body computer. What do you think of this idea? Does it sound cool, like being a character in the movie RoboCop? Or would you prefer to be just an ordinary human being? 52．What's the main idea of the passage?
A．Technology is causing us to be lazy. B．Technology is doing harm to our body. C．Technology is advancing too quickly. D．Technology is making our life easier.
53．Which of the following is NOT the way to exchange information over the skin?
A．Shaking hands.
B．Looking into one's eyes. D．Dancing cheek to cheek.
C．Kissing each other.
54．The body network is safer because _________.
A．the information is only important to you B．the information is stored inside your body
C．the information is sent out only 20cm from your body D．the information is controlled by your nervous system 55．The movie RoboCop is most likely about________.
A．a man that is controlled by a computer B．a computer that turns into a man C．a robot that catches a thief D．a thief that steals a robot

public library system got its biggest development in the American history in the late 1800's. Businessman Andrew Carnegie donatedmillions of dollars to help build （捐赠）free public libraries across the country. 57．
58． young and old. He knew that the more libraries there were, the more people would have opportunities to read and use books, speeches and news.

Seven tenths of the libraries have free Internet. 59． 60． The new program Read! Build! Play! adds reading into playtime. As kids listen to a book that is being read aloud, they use Legos (乐高积木) to build images (图像) from the story happily. Today's libraries are always looking for creative programs to bring people into the library.
Benjamin Franklin once said, \(智慧) are never shut.\long as the doors of public libraries are open, what he said is most certainly correct!
