阅读理解      Water is very important to living things. Without water there can be no life on the earth. All animals
and plants need water. Man also needs water. We need water to drink, to cook our food and to clean
ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.
      There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part
of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The
water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapor (蒸气).
      Clouds are made of water. They may be made of very small drops of water. They may also be made
of snow crystals(结晶体). Snow crystals are very small crystals of ice. Ice is frozen water. It is a solid.
There can be snow and ice everywhere in winter.
     Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is
a liquid, you can drink it. When it is a gas, you can not see or feel it.

1. Where can we find water?

阅读理解     We know, painkillers in a tablet can make your headache go away, and antibiotic from a tube can
prevent your cuts from becoming infected. Can medicine come in chicken eggs? A team of scientists
from Scotland says "yes." They"ve kept some special chickens that lay eggs with disease-treating drugs
inside.
     These drugs are made of molecules called proteins. Animals make thousands of proteins-they"re the
main ingredients(成分) in skin, hair, milk, and meat. Since animals can make proteins easily, they"re
good animals for making protein drugs.
     Researchers have already made cows, sheep, and goats that pump out protein drugs in their milk.
But chickens are cheaper to take care of, need less room, and grow faster than these other animals.
"Those qualities could make chickens a better choice to become living drug factories." says Simon
Lillico of the Roslin Institute near Edinburgh, Scotland.
     Lillico and a team of researchers changed chickens" DNA-the code that tells cells how to make
proteins-so that the birds" cells made two protein drugs. One drug can treat skin cancer, and the other
treats a nerve disease called multiple sclerosis.
     The scientists changed the chickens" DNA so that the birds made these drugs only in their egg whites.
This protects the chickens" bodies from the drugs" possible harmful effects and makes it easy for scientists
to collect the drugs.
     These special chickens can pass on their drug-laying abilities to their chicks. So far, the Scottish
researchers have kept five generations of drug-producing chickens. But the scientists need to improve
these chickens. The chickens don"t make enough drugs to treat people yet. Once the researchers perfect
their technique, you might eventually take your medicine from chicken eggs.

1. What is the best title of the passage?

A. Animals and Protein Drugs.
B. Medicine Packaged in Various Forms.
C. A Scotland Scientist and His Chickens.
D.Chickens: a Better Choice of Living Drug Factories.

2. Which of the following is Not True according to the passage?

A. It takes much shorter time for chickens to grow than cows, sheep and goats.
B. Compared to cows, sheep and goats, chickens are less expensive to be raised.
C. Chickens can produce the best quality of drugs among the drug-producing animals.
D. Chickens are smaller in size than cows, sheep and goats and therefore need less room.

3. Why did the chickens make the drugs only in the egg whites?

A. Because it will help to collect the drugs easily.
B. Because it will not change the DNA of the chickens.
C. Because it will be easy for the patients to take the drugs.
D. Because it will prevent possible harmful effects on the patients.

4. What can be inferred from the passage?

A.Scottish researchers have kept five more drug-producing chickens.
B.This technique still needs improving so as to satisfy the normal application.
C.In the future people with diseases will take eggs instead of pills.
D.  The chicks need to be improved so as to carry the same ability as their parents.

Attitudes to AIDS Now
     Most people say that the USA is making progress in fighting AIDS, but they don"t know there"s no cure and strongly disagree that "the AIDS epidemic(流行病)is over," a new survey finds.
     The findings, released Thursday by the Kaiser Family Foundation, reassure activists who have worried
that public concern about AIDS might disappear in light of recent news about advances in treatment and
declines in deaths.
     "While people are very optimistic about the advances, they"re still realistic about the fact that there is no cure" says Sophia Chang, director of HIV programs at the foundation.
     The Kaiser survey, like a recent USA TODAY Gallup Poll, does find that the number of people
ranking AIDS as the country"s top health problem has fallen. In the Kaiser Poll, 38% say it"s the top
concern, down from 44% in a 1996 poll; in the Gallup Poll, 29% say AIDS in No.1, down from 41% in
1992 and 67% in 1987.
     Other findings from Kaiser, which polled more than 1,200 adults in September and October and asked additional questions of another 1,000 adults in November:
     52% say the country is making progress against AIDS, up from 32% in 1995.
     52% say the government spends too little on AIDS.
     86% correctly say AIDS drugs can now lengthen lives; an equal number correctly say that the drugs are not cures.
     67% incorrectly say that AIDS deaths increased or stayed the same in the past year; 24% know deaths fell.
     Daniel Zingale, director of AIDS Action Council, says, "I"m encouraged that the American people are
getting the message that the AIDS epidemic isn"t over. I hope the decision-makers in Washington are
getting the same message… We have seen signs of complacency(自鸣得意).
1. According to the Kaiser Poll, which of the following is NOT correct?
A. The country is making progress against AIDS.
B. AIDS drugs still cannot save people"s lives.
C. AIDS drugs can now make people live longer.
D. More and more people die of AIDS now.
2. The word "message" in the last paragraph means     .
A. printed new
B. contact
C. meaning
D. central idea
3. What do activists worry about?
A. Recent news about AIDS is not true.
B. People may stop worrying about AIDS.
C. Deaths caused by AIDS may not decline.
D. Advances in AIDS treatment are too slow.
4. According to the passage, people"s attitude toward the cure of AIDS is       .
A. optimistic.
B. hopeless.
C. pessimistic
D. realistic.
5. The Gallup Poll shows that the number of people      .
A. who suffer from the worst disease--- AIDS has fallen.
B. who think AIDS threatens the countryside has fallen.
C. who worry about AIDS and health problems has fallen.
D. who think AIDS is the country"s top health killer has fallen.

     What will people die of 100 years from now? If you think that is a simple question, you have not been
paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new
medicine, the human body will last a very long time. Death will come mainly from accidents, murder and
war. Today"s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
     In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains
were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently,
scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new
medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on-in much the same way our bodies make new skin cells to take the place of old ones.
     It is exciting to imagine that the advance in technology may be changing the most basic condition of
human existence, but many technical problems still must be cleared up on the way to this wonderful future.
1. The author thinks the question how people die in the future __________.
A. is simple
B. is funny
C. has something to do with bio-technology
D. has something to do with environment

A. diseases and aging
B. accidents and war
C. accidents and aging
D. heart disease and war
3.In the author" s opinion, today"s most important advance in technology lies in         .
A. medicine
B. the Internet
C. brain cells
D. human organ
4.Humans may live longer in the future because         .
A. heart disease will be far away from us
B. human brains can decide the final death
C. the basic materials of cells will last forever
D. human organs can be repaired by new medicine
5.We can learn from the passage that        .
A. human life will not last more than 120 years in the future

     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 Milan and Michele Tavella from the Federal Polytechnic school in
Lausanne, Switzerland, demonstrated(展示)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 ceils. These send signals through the spinal cord(脊髓)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(头皮) 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. Milan, 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.
1. BCI is a technology that can ________.
A. help to update computer systems
B. help the disabled to recover
C. link the human brain with computers
D. control a person"s thoughts
2. How did Tavella operate the wheelchair in the laboratory?
A. By controlling his muscles.
B. By talking to the machine.
C. By using his mind
D. .By moving his hand.
3. Which of the following shows the path of the signals described in Paragraph 5?
A. scalp→computer→cap→wheelchair
B. computer→cap→scalp→wheelchair
C. cap→computer→scalp→wheelchair
D. scalp→cap→computer→wheelchair
4. 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. Robotic Vehicles Could Help to Cure Brain Injuries
D. BCI Could Mean More Freedom for the Disabled
