Recently we had a discussion about whether it is necessary to have daily homework. 70% of my classmates are willing to accept as daily homework. They think homework helps them review that has been taught in class. Besides, by doing daily homework, they can well understand and memorize their lessons. Furthermore, their skills in managing time can too be improved. However, 30% the students have different idea. They believe that homework reduces their amount of time with their families, not mention the time for other activities. With much homework to do, students feel tiring, and will gradually lose interest in their lessons. In my opinion, daily homework is necessary, and it must serve a purpose and be fit to a student's ability. Also, the amount of homework should be limiting.

¡¾ÌâÄ¿¡¿Severely disabled people may soon be able to use their noses to write, drive a wheelchair or surf the Internet, thanks to a device (×°ÖÃ) developed by doctors in Israel.

The device will be used by breathing in and out through the nose, according to a study. Healthy people who tested the device quickly learned to play computer games and write sentences by sniffing. Encouraged by the results, the researchers decided to test their device on people who are paralyzed (̱»¾) but whose intelligence remains normal. Ten paralyzed who tested the device quickly learned to use their noses to write words, open a webpage, copy words and put them into a search engine.

With their success in helping severely disabled people to communicate * the researchers decided to make use of the new technology to design an electric wheelchair to be driven by sniffs.

Ten healthy people easily mastered sniff¡ªdriving a wheelchair through a maze (ÃÔ¹¬), and a 30-year-old man who had been paralyzed from the neck down for six years was as good a sniff-driver as the healthy participants at his second attempt. In other words, a paralyzed person could use the sniff controller to drive an electric wheelchair.

At the moment, sniff-controlled technology is still in the stage of development, and the Weizmann Institute has already applied for a patent on the device. "Ill be very happy if it can help us to make money, but the real problem is that I hope someone will develop it, because this would help a lot of people," said Sobel, one of the lead researchers of the study.

Tips to Ease Migraines

If you've ever experienced migraine headache, you know that it's no walk in the park. Migraines are very painful type of headache, often felt on one or both sides of a head. Some people experience migraines every now and then, while others get them more than once a week. ¡¾1¡¿ Although they are not dangerous to life, migraines can seriously affect one's ability to function throughout the day. Here are four tips for easing migraines:

1. Learn to manage. Migraines are often caused by stress, so try not to get stressed out easily. ¡¾2¡¿ Learning stress management techniques can reduce and even prevent the pain of a migraine headache. You can do this by taking a yoga lesson. If you prefer to practice relaxation at home, then try lying down on your bed or sofa and closing your eyes. Take slow, deep breaths and focus on relaxing each muscle group one at a time until you hate relaxed every single muscle in your body.

2. Use ice massage(°´Ä¦). Another solution is the "ice massage". Put your fingers into ice-cold water and then press your temples(Ì«ÑôѨ) until the pain decreases. ¡¾3¡¿

3. Drink lots and lots of water. You can also get migraines if your body lacks water. Avoid dehydration by staying out of the sun and drinking plenty of water throughout the day. Carry a water bottle with you. ¡¾4¡¿

4. ¡¾5¡¿ When you have a migraine, lights and sound can sometimes be your worst enemy. Close your curtains, turn out the lights, and remember to turn off the TV.

A . Add a few drops of peppermint(񭧐) oil for an even stronger effect.

B. Create a dark space to rest.

C. But never drink coffee, tea, or soda, for these may cause migraines.

D. But never wear headphones for too long, since it may cause migraines.

E. Avoid bright lights and loud noises.

F. Avoid using the computer for too long and going to bed late at night.

G. About 6 in every 100 people regularly experience migraine headaches.

¡¾ÌâÄ¿¡¿Computer technology is still developing rapidly. The computer of the future will continue to increase in value and performance while decreasing in cost. It will become smaller, but faster and more powerful.

It is possible to make some guesses about what the future of the computer will look like, based upon the types of technologies that are being developed now. A lot of progress has already been made in some of these new technologies, but some are still in their earliest stages and may not be ready for use for years. Two of the most interesting areas of computing that are currently being developed are quantum computing (Á¿×Ó¼ÆËã) and nanotechnology (ÄÉÃ×¼¼Êõ).

Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today. Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time.

Nanotechnology could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size. These computers could be incorporated (²¢Èë) into everyday objects, including electrical appliances (µçÆ÷), clothes and even the human body. We will be able to use computers in new and unimaginable ways. They will become a part of our lives rather than simply being a box that is used only for specific purposes, such as work.

Quantum computing and nanotechnology will be able to play new roles, which will make us live greener lives, as well as enjoy better health and happier lives.

¡¾1¡¿Which of the following can NOT describe the computer of the future properly?

A. Much smaller.

B. Much faster.

C. More powerful.

D. Less valuable.

¡¾2¡¿According to the text, quantum computing _____.

A. has been put in use so far

B. can make computers run by themselves

C. can reduce the cost of computers

D. will work by using transistors

¡¾3¡¿We can learn from the text that nanotechnology will _____.

A. create much smaller computers

B. be used in electrical appliances and clothing

C. change the structure of computers

D. make computers just serve specific purposes

¡¾4¡¿The text is mainly about _____.

A. what nanotechnology is

B. what quantum computing is

C. what the future of the computer is

D. what future computers can bring us
