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.
B. only in books written for children
C. in books written today and hundreds of years ago
D. as a new development in literature
B. writing about everything but politics
C. imagining future world with the results of technical developments
D. writing space adventure stories
B. shows the writer"s viewpoints
C. is not as good as that in the past
D. is better than other literary forms
B. adopting new technology and adapting quickly to its effect on society
C. conflict caused by different religious beliefs
D. space adventure
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.

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 _________________.
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?
B. computer→cap→scalp→wheelchair
C. scalp→cap→computer→wheelchair
D. cap→computer→scalp→wheelchair
4. The team will test with real patients to .
B. prove the technology useful to them
C. make them live longer
D. learn about their physical condition
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
school in 2 I have ever taught has ever ignored spelling or considered it unimportant as a basic
skill. There are, however, different ideas about how to teach it, or how much priority(优先) it must
be given over general language development and writing ability. The problem is how to encourage a
child to express himself freely and confidently in writing 3 holding him back.
If spelling becomes the only focal(焦点的) point of his teacher"s interest, clearly 4 bright child
will be likely to "play safe". He will tend to write only words within his spelling range, 5 (choose)
to avoid adventurous language. That"s why teachers often encourage the early use of dictionaries and
pay attention to content rather than technical ability.

beautiful expressions of the child"s deep feelings. The teacher was not wrong to draw attention to
the errors, 10 if his priorities had centered on the child"s ideas, an expression of his disappointment
with the presentation would have given the pupil more motivation to seek improvement.
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.
B. By giving off particular smells.
C. By making soft and beautiful sounds.
D. By the signals sent by parasitic wasps.
B. choose to leave the plant
C. compete for the same plant
D. fight with the root-eating insects
B. are not occupied by mot-eating insects
C. have more green leaves
D. have more subterranean insects
A. Aboveground insects.
B. Root-eating insects.
C. Caterpillars.
D. Parasitic wasps.
B. How do animals avoid competition?
C. Insects use plants as telephones
D. When plants have subterranean residents
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 expo
sures will cause unnecessary fear．However,theresearchers found that the women in their study were typically not alarmed,and instead wanted "more
rather than less" information on the issue．
le 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．
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 building
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 immediately
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．
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余项。
familiar, the reading comprehension is no problem, and you are speaking quite fluently. 1
First of all, remember that you are not alone. Listening is probably the most difficult job for almost
all learners of English as a foreign language. 2 what you need to do is to find listening resources. The
Internet is really a useful tool for English students. You can download The RealPlayer from RealMedia.
com. The Real Player allows you to use the Internet like a radio station.
Once you have begun to listen on a regular basis, you might still be frustrated(受阻)by limited
understanding 3
Here is some of the advice I give my students:
Accept the fact that you are not going to understand everything.
Stay relaxed when you do not understand, and try listening to the material for more times.
Do not translate everything into your native language .
4 Don"t concentrate on detail until you have understood the main ideas.
Listen to something you enjoy.
I remember the problems I had in understanding spoken German when I first went to Germany. In
the beginning, when I didn"t understand a word, I insisted on translating it in my mind. 5 Then, after
the first six months, I discovered two extremely important facts; Firstly, translating creates a barrier
between the listener and the speaker. Secondly, most people repeat themselves constantly. By remaining
calm, I noticed that even if I didn"t pay much attention I could usually understand what the speaker had
said.
A. What should you do?
B. But listening is a problem for most of the beginners!
C. However, after several weeks, I got used to the grammar rules
D. The most important thing is to listen as often as possible.
E. This method usually resulted in confusion.
F. Listen for the general idea of the conversation.
G. But you can"t follow a native English speaker at all!
