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. |

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 forms |
| 4. 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 adventure |
| 5. 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. |

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 |

There is a popular belief among parents 1 schools are no longer interested in spelling. No
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.
Once I 6 (shock) to read on the bottom of a sensitive piece of writing about a personal
experience. "This work is horrible! There are far too many spelling errors and your writing is terrible.
" 7 may have been a sharp criticism of the pupil"s technical abilities in writing, but it was also a sad
8 (reflect) on the teacher who had omitted(忽视) to read the essay, 9 there existed some
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. |

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 insects |
| 4. 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 |

Does this situation seem familiar to you? Your English is progressing well, the grammar is now
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! |
