阅读理解。      Man is a land animal, but he is also closely tied to the sea. Throughout history the sea has served
the needs of man. The sea has provided man with food and a convenient way to travel to many parts
of the world. Today, nearly two-thirds of the world"s population live within 80 kilometers of the sea
coast.
      In the modern technological world, the sea offers many resources to help mankind survive.
Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many
of man"s needs.
     The list of riches of the sea yet to be developed by man"s technology is impressive. Oil and gas
explorations have been carried out for nearly 30 years. Valuable amounts of minerals exist on the
ocean floor ready to be mined.
     Fish farming promises to be a good way to produce large quantities of food. The culture of fish
and shellfish is an ancient skill practiced in the past mainly by Oriental people.
     Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm
temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents
and waves offer possible use as a source of energy.
     Technology is enabling man to explore ever more deeply under the sea. The development of
strong, new materials has made this possible.
     The technology to harvest the sea continues to improve. Experts believe that by the year 2050
the problems that prevent us from exploiting fully the food, minerals, and energy sources of the sea
will be largely solved.1. What is the beat title for the passage?A. Needs of Man.              
B. Sea Harvest and Food
C. Sea and Sources of Energy    
D. Sea Exploring Technology.2. It can be inferred from the passage that ______.A. man hasn"t completely made use of the riches of the sea
B. technology for exploring the sea has been solved
C. harvesting rice in the sea will be made possible
D. in the near future man can live on the ocean floor3. Why does the author mention a steamship in paragraph 5?A. To illustrate that man can make use of sources of energy from the sea.
B. To show that a steamship is better than other kinds of ships.
C. To argue that man should use steamships.
D. To indicate that it is warmer in the ocean than on land.4. According to the author, technology is important because ______.A. resources on land are running short in ten years
B. man can use it to explore the deeper sea
C. it is a lot of fun diving into the sea
D. ancient people used it to explore the sea5. According to the author, when will the problems to explore the deeper sea largely be solved?A. In the next generation.              
B. At the end of the 20th century.
C. In the near future.                  
D. By the middle of the 21st century.

阅读理解。    Among the most popular books being written today are those which are usually classified as science
fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore,
some of the most successful films in recent years have been based on science fiction stories. 
    It is often thought that science fiction is a fairly new development in literature, but it can be found in
books written hundreds of years ago. These books were often concerned with the presentation of some
form of ideal society, a theme which is still often found in modern stories.
    Most of the classics of science fiction, however, have been written within the last one hundred years.
Books by writers such as Jules Verne and H. Wells, to mention just two well-known authors, have been
translated into many languages. Modern science fiction writers don"t write about men from Mars or space
adventure stories. They are more interested in predicting the results of technical developments on society
and the human mind or in imagining future world which results the world we live in now. Because of this
their writing has obvious political undertones. 
    In an age where science fact frequently overtakes science fiction, the writers may find it difficult to keep ahead of scientific advances.Those who see the future clearly can teach us how to master new technology
and live in a rapidly changing world. 1. You can find science fiction ______. A. only in modern literature
B. only in books written for children
C. in books written today and hundreds of years ago
D. as a new development in literature 2. Modern science fiction writers are interested in ______. A. writing about men from Mars
B. writing about everything but politics
C. imagining future world with the results of technical developments
D. writing space adventure stories 3. It can be concluded that modern science fiction____________.A. reflects social political reform
B. shows the writer"s viewpoints
C. is not as good as that in the past
D. is better than other literary forms4. Science fiction writers may provide a valuable lesson on how to deal with the problems of ______. A. conflict used by different political theories
B. adopting new technology and adapting quickly to its effect on society
C. conflict caused by different religious beliefs
D. space adventure5. Which of the following statements is NOT true?A. Science fiction often overtakes science fact.
B. Writers may find it hard to keep ahead of scientific advances.
C. Some of the most successful films of recent years have been based on science fiction stories.
D. Those writers who can see clearly the way we are going will give us valuable instructions.

阅读理解。     Since the 1970s, scientists have been searching for ways to link the brain with computers.
Brain-computer interface (界面) (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 cells. 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. link the human brain with computers
C. help the disabled to recover                
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 moving his hand.                        
D. By using his mind.

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. scalp→cap→computer→wheelchair
D. cap→computer→scalp→wheelchair 

4. The team will test with real patients to                         .

A. make profits from them          
B. prove the technology useful to them
C. make them live longer            
D. learn about their physical condition      5. 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. BCI Could Mean More Freedom for the Disabled
D. Robotic Vehicles Could Help to Cure Brain Injuries

阅读理解。     Science Daily (Apr. 27, 2008)-- Dutch ecologist Roxina Soler and her colleagues have
discovered that subterranean (地下的) and aboveground herbivorous (食草的) insects can
communicate with each other by using plants as telephones.  Subterranean insects issue chemical
warning signals through the leaves of the plant. This way, aboveground insects are warned that the
plant is already "occupied".
     Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean
root-eating insects. Subterranean insects send out chemical signals through the leaves of the plant,
which warn the aboveground insects about their presence. This messaging makes it possible for
spatially-separated insects to avoid each other, so that they do not compete for, the same plant.
     In recent years it has been discovered that different types of aboveground insects develop slowly
if they feed on plants that also have subterranean insects and "vice versa (反之亦然). It seems that a
mechanism (机制) has developed through natural selection,  which helps the subterranean and
aboveground insects to communicate with each other. This avoids unnecessary competition.
      Through the "green telephone lines", subterranean insects can also communicate with a third party,
namely the natural enemy of caterpillars (毛虫). Parasitic wasps (寄生蜂) lay their eggs inside above
ground insects. The wasps also benefit from the signals sent by the leaves, as these help them find more
insects for their eggs.
     The communication between subterranean and above- ground insects has only been studied in a
few systems. It is still not clear how widespread this phenomenon is, say the researchers.1. How do subterranean and aboveground insects communicate with each other?A. By sending signals through the leaves.    
B. By giving off particular smells.
C. By making soft and beautiful sounds.    
D. By the signals sent by parasitic wasps.2. After finding a plant occupied by root-eating insects, aboveground insects will usually ________.  A. send out warning signals        
B. choose to leave the plant
C. compete for the same plant      
D. fight with the root-eating insects 3. Aboveground insects will develop more quickly if their food plants ________.   A. are often visited by parasitic wasps    
B. are not occupied by mot-eating insects
C. have more green leaves            
D. have more subterranean insects4. What does the underlined part "a third party" in Paragraph 4 include?  

A. Aboveground insects.  
B. Root-eating insects.
C. Caterpillars.        
D. Parasitic wasps.

5. What would be the best title for the passage?   A. Communication between different insects
B. How do animals avoid competition?
C. Insects use plants as telephones
D. When plants have subterranean residents

阅读理解。     Many people may be surprised by the number of chemicals that they are exposed to through
everyday household products.
     In a study 25 women had their homes and bodies tested for 89 environmental pollutants-including
pesticides (***虫剂) and chemicals found in plastics and cleaning products.On average 20 chemicals
were found on their bodies or in their homes.
     Much is unknown about the possible health effects of chemicals in everyday household products.
But certain chemicals-like phthalates (邻苯二甲酸盐) found in plastics-have been linked to potential
health risks,including higher risks of certain cancers,though the evidence mainly comes from research
on lab animals.Other household chemicals are known to harm the skin,eyes and airways-and may
worsen asthma (哮喘).Many more chemicals found remain untested.
      Chemicals likely come from a range of sources,so it is not always clear how to reduce people"s
exposure,according to Dr.Rebecca Altman,the lead researcher on the new study."However," she
said,"there are still measures people can take."
      In the original study,she noted,women were given advice based on the particular chemicals they
were exposed to-such as using fragrancefree washing liquid and personalcare products.
For the current study,Altman and her colleagues interviewed two dozen women who"d taken part in
the previous study to see how they would react to information about their household chemical exposures.They found that the women were generally surprised at the range of chemicals found in their homes and
bodiesThey were also surprised that even some banned things were found.
     With many questions about the health effects of household chemicals unanswered,some experts worry
that giving people information about their everyday exposures will cause unnecessary fear.However,the
researchers found that the women in their study were typically not alarmed,and instead wanted "more
rather than less" information on the issue.1.Which of the following statements about chemicals in household products is TRUE?A.Some of them have bad effects on health,while some have good effects.
B.Longterm exposure to them is certain to cause a deadly illness.
C.In the study it was found that certain chemicals can cause cancers.
D.It is uncertain what effects some chemicals have on health.2.The underlined word "airways" in Paragraph 3 most probably refers to ________.  A.the passage running from your nose and throat to the lungs
B.things that look like fine threads growing in the body
C.the passage between rows of rooms in a building
D.the area just inside the front door of a building3.According to Dr.Rebecca Altman,________.A.women were more likely to be harmed by chemicals
B.fragrant products may contain harmful chemicals
C.it is unnecessary to inform people about the study results
D.further study on everyday products should be done immediately4.What was the women"s attitude towards the study results?A.They were angry that so many chemicals were found.
B.They refused to be subjects for the study any more.
C.They were afraid of getting bad news about their health.
D.They would like to know more related information.
