worry that it may be "running out of control". This idea is dangerous.
Science can be a force for evil as well as for good. Its applications can be channeled either way, depending
on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science.
But here is a real danger. Science is advancing so fast and is so strongly influenced by businesses that we are
likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the
best possible policies, we may step back and do nothing.
Some people go even further. They say that despite the moral and legal objections (反对), whatever is
scientifically possible will be done-somewhere , sometime. They believe that science will get out of control in
the end. This belief is dangerous too, because it fuels a sense of hopelessness and discourages then from
making efforts to build a safer world.
In our interconnected world, the lack of agreement in and out of the world of science can lead to the failure
to control the use of science. Without a common understanding, the challenges of "controlling" science in this
century will be really tough. Take human cloning for example. Despite the general agreement among scientists
on its possible huge impact (影响) on traditional moral values, some countries still go ahead with the research
and development of its related techniques. The outcomes are hard to predict.
Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only
through the untied efforts of people with hope, can we be fully safe against the misuse of science and can
science best serve mankind in the future.
B. People hold mixed opinions about science.
C. Science is getting dangerously out of control.
D. Science is used for both good and bad purposes.
B. Businesses will have even greater influence on science.
C. The public will lose faith in bringing about a bright future.
D. People will work more actively to put science under control.
B. the ties between different areas need strengthening
C. united efforts are necessary for the development of science
D. people need to work together to prevent the bad use of science
B. The development of science mostly lies in people"s attitudes.
C. Mankind can largely take control of science with their efforts.
D. The future of science will be influenced by the dangerous ideas.

danger today because of Google"s new tracking system. In a motion (提案), they also warned that the system
offers live tracking of mobiles through a website and called on Google to examine the service.
The Latitude system can find where a user is. This is then broadcasted live to Google"s website. Once the
service is activated, the position of a person"s phone appears as a blue dot on a map on the screen of whoever
is allowed to monitor (监控) them. The Latitude feature is being developed by Google as a "fun" way to "keep
tabs on someone special". More than a million users around the world have already signed up to the service,
Google claims.
However, concerns have been raised about the system. MPs have written to Google demanding extra
security (安全) safeguards on the service.
Mr. Brake, one of the MPs who raised the motion, said,"In Britain, we have a tradition of fighting for our
freedom. With this new system we face a threat to it. I demand MPs to support this motion and encourage the
Government to take action to ensure that Latitude does not represent a threat to our privacy. or our freedom
could be in danger."
Google today insisted there was no threat to privacy.It said it was up to users to decide whether to make
their location visible to other people and to decide who could monitor their position.The service was designed
to help people keep in touch.
However, human rights watchdog Privacy International analyzed the service and claimed it was open to
abuse (滥用). Its report claimed employers could supply employees with phones already set up to use the
service without their knowledge, or that users could simply sign up their partner"s or child"s mobile phone
without telling them.
B. they have required Google to examine the service
C. they hope that the Government will take some measures
D. they are trying to get help from other countries
B. support
C. test
D. monitor
B. They think it is fun and can help them keep in touch.
C. They can get it at a lower price.
D. It"s convenient to travel across the world.
B. polite
C. doubtful
D. positive
Outside of class, the most natural way of finding out if you are making mistakes is from other people"s
responses. If the mistakes are too serious, your listeners will be asking you all the time what you mean. If
they are not so serious, then people may be asking you whether you said such and such. That will tell you
how close you are to speaking "cogently".
Of course, there are other times when it is important to have errors pointed out. Your class assignments
(作业) are probably marked in this way, in which case you need to spend time going over them to take
advantage of the individual feedback. In some classes the teacher gets better and better at grammar because
she does all the corrections, but the students make slow progress if, when an assignment is returned, they
quickly stuff it into their folders without looking.
You are the person who should be connecting your error, even if the marker has signaled them, when
you look at them; there are some steps to work through. One distinction that has been made about learners"
language is this. You make mistakes about rules that you already know but you make errors about points
you haven"t learned yet. In other words, you can find your own mistakes, but not your errors. First, make
sure you understand what you have written or said, or your correction will simply be another stab at the
right answer. Next, decide on the best way of practicing the correct form. Would it help you to write out
the sentence once more? Can you make up another similar sentence? Then you could test yourself in a few
days time to see whether you have remembered the right form, anyone can get it right immediately after
being told. He challenge is to remember it and apply it later.
B. speaking is the only way to correct mistakes
C. getting and using responses is important
D. errors can be easily corrected
B. By practicing the correct forms.
C. From the teacher"s getting better and better at grammar.
D. From your listeners responses.
B. they have remembered the right form
C. they hardly pay attention to their marked assignments
D. they decide on the best way of practicing the correct form
B. Writing out the sentence once more.
C. Learning your mistakes by heart.
D. Correcting your mistakes and writing down the teacher"s words.
bear; it is not even a mammal (哺乳动物), but a marsupial (有袋动物), like the kangaroo. Its closest living
relatives are the wombats (毛鼻袋熊). A koala is about 60-80cm long and weighs 5-14kg.
The name "koala" means "no drink", and refers to the koala"s ability to go for days without water. Koalas
get the water content they need from the eucalyptus (桉树) leaves on which they feed. The koala is the only
mammal with a digestive system that can feed only on eucalyptus leaves-incidentally, these leaves are highly
poisonous if eaten by humans. One individual consumes about 5kg of eucalyptus leaves daily and it may never
drink water!
The koala is a nocturnal mammal. They prefer to move around just after sunset, spending daytime sleeping
in the form of a tree. A koala spends sleeping 75% of its time. The eucalyptus leaves they eat are rich in fiber
and poor in proteins and fats. The adult must detoxify (排毒) leaves with energy expense, while fiber is hard
to break down. Because of this poor diet, koalas save energy by sleeping most of the day, while their
movements are very slow.
Koalas only have one young per year. In summer, baby koalas are born about a month after mating. The
female takes it with her mouth and places it into her poach. In 6 months, the young can get out and feed on
leaves. There are probably around 2,000 to 8,000 wild koalas in Australia at present. The extremely fine gray
fur is the reason why koala has been heavily hunted in the past. Koalas are killed every year by dogs, cats,
dingoes, eagles and owls. They also die of disease and accidents.
B. living habitat
C. digestive system
D. born laziness
B. To save its energy.
C. To protect itself from the sun.
D. To detoxify eucalyptus leaves.
B. excited in the daytime
C. inactive during the night
D. upset in the daytime
B. Living areas of the koala.
C. Ways the female feeds her young.
D. The decreasing number of the koala.
can also help to find lung and breast cancer, researchers report in integrative Cancer Therapies. The findings
show that trained ordinary household dogs can detect early-stage lung and breast cancers by smelling the
breath samples of patients.
Researchers have found that cancer cells send out molecules different from those of healthy ones, and that
might be sensed by smell by the highly sensitive dog"s nose.
For the study, five dogs were trained by a professional instructor to respond differently to breath samples
of healthy and cancer patients. "The dogs learned to sit or lie down in front of cancer patient samples and to
ignore control samples through the method of food reward," McCulloch explained.
After a period of training,researchers tested the animals" ability to distinguish cancer patients from controls.
The animals were given breath samples from 55 patients with lung cancer, 31 with breast cancer and 83 healthy
controls who were not included in the original training period.
McCulloch"s group found that the dogs were able to correctly distinguish the breath samples of cancer
patients from those of the control subjects in about 90 percent of the cases. The dogs were also able to
detecting early-stage lung and breast cancers.
"These results show that there is hope for early detection," McCulloch said. The re-searches are planning to
conduct further studies on the breath composition of cancer patients to possibly design an electronic device that
can do the dogs" job. "A dog"s nose is so powerful it can detect odors (气味) 10 000 to 100 000 times better
than a human nose can. I hope people will be interested in doing this research," McCulloch added, "It shows
that there is definitely something out there."
B. 5 dogs and 86 people
C. 10 dogs and 83 people
D. 5 dogs and 169 people
B. to recognize differences of
C. to remember somebody forever
D. to discomfort somebody
B. the final goal of the researchers is to design an electronic dog to detect cancer
C. dogs can detect odors 10 000 to 100 000 times better than humans can
D. dogs will soon be widely used to smell signs of cancers in hospitals
B. Dogs and Cancer
C. Dogs Smell Signs of Cancer
D. McCulloch"s New Discovery
the information that has been presented. This is the concluding sentence. The concluding sentence is similar
to the topic sentence. They are both general sentences. The concluding sentence can be written in two ways:
1. State the topic sentence in different words.
2. Summarize the main points in the paragraph.
You can understand concluding sentences with this example. Consider a hamburger that you can buy at
a fast-food restaurant. A hamburger has a top bun, meat, cheese, lettuce (生菜), and other elements in the
middle of the hamburger, and a bottom bun. Note how the top bun and the bottom bun are very similar. The
top bun, in a way, is like a topic sentence, and the bottom bun is like the concluding sentence. Both buns
"hold" the meat, onions, and so on. Similarly, the topic sentence and concluding sentence "hold" the supporting
sentences in the paragraph. Let"s see how a concluding sentence might look in our sample paragraph about
Wheaton:
My hometown is famous for several amazing natural features. First, it is noted for the Wheaton River,
which is very wide and beautiful. Also, on the other side of the town is Wheaton Hill, which is unusual because
it is very steep. The third amazing feature is the Big Old Tree. This tree stands two hundred feet tall and is
probably about six hundred years old. These three landmarks are truly amazing and make my hometown a
famous place.
Notice how the concluding sentence, "these three landmarks are truly amazing and make my hometown
a famous place", summarizes the information in the paragraph. Notice also how the concluding sentence is
similar to, but not exactly the same as, the topic sentence.
Usually, we begin a concluding sentence with "in conclusion" or "in summary". Remember, not all
paragraphs contain concluding sentences,especially if the paragraph is very short. However, if your paragraph
is very long, it is a good idea to use a concluding sentence.
B. What the top bun and the bottom bun are like.
C. Why his hometown is a famous place.
D. To use a concluding sentence in our writing.
B. Because a hamburger has a top bun and a bottom bun.
C. Because the top bun and the bottom bun are very similar.
D. Because he wants to explain his main idea in another way.
B. famous
C. noticed
D. recorded
B. All paragraphs contain concluding sentence.
C. It is a good idea to use a concluding sentence in a long paragraph.
D. The concluding sentence is the same as the to pic sentence.
B. natural features,the Wheaton River and the Wheaton Hill
C. the Wheaton River,Wheaton Hill and the Big Old Tree
D. my hometown,Wheaton Hill and the Big Old Tree
