【题目】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 (量子计算) and nanotechnology (纳米技术).
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 (并入) into everyday objects, including electrical appliances (电器), 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.
【1】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.
【2】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
【3】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
【4】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

In China, people and giant pandas had been living together for thousands of years. But China’s human population has been great growing. More population means more land is needed for farming. It also mean more forests are cut for wood to build and heat houses. Loss of habitat in lowland areas has forced pandas live only in the mountains. The most damaged result of development has been that it has divided the panda’s habitat into little islands of forest. Today, many panda are isolated in these small sections of forest, because of they will cross into areas which people live. The result is that the giant pandas can connect with one another to mate and have babies.
Besides, to our relief, there is still some good news that people are trying to help the giant pandas by creating protected areas.

【题目】The weather predictions for Asia in 2050 read like a story from a doomsday movie．
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring．In the decades to come, Asia—home to more than half the world's 63 billion people—will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels．
"It's not a pretty picture," said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam．Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come．
Already, changes are being felt in Asia but worse is likely to come．Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters．According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate or build sea defenses, storms will become stronger and insects and water-borne diseases will move into new areas as the world warms．
All this comes on top of rising populations and demand for food, water and other resources．Experts say environmental worsening such as deforestation and pollution will likely enlarge the results of climate change．
In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two - thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill．

People who are near-sighted can only look things that are very close to their eyes. Everything before their eyes seem unclear. Many people do a lot of close work, writing, reading and sewing become near-sighted. So they have to wear glass so as to see distance objects clearly. People who are far-sighted suffered from just the opposite problem. Although they can't see things that are far away, they have difficulty reading a book if they hold them at an arm's length. If they want to do many reading, they have to wear glasses, too. Other people do not see clearly because of their eyes aren't exactly of the right shape.
