Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules (分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP. What is the text mainly about?
| A．The terrible conditions in the Antarctic. |
| B．A special fish living in freezing waters. |
| C．The ice shelf around Antarctica. |
| D．Protection of the Antarctic cod. |
Why can the Antarctic cod live at the freezing temperature?
| A．The seawater has a temperature of - l.88℃ |
| B．It loves to live in the ice-salt mixture. |
| C．A special protein keeps it from freezing. |
| D．Its blood has a temperature lower than -2.05℃ |
What does the underlined word “it” in Paragraph 5 refer to?
| A．A type of ice-salt mixture. | B．A newly found protein |
| C．Fish blood. | D．Sugar molecule. |
What does “glyco-” in the underlined word “glycoprotein” in the last paragraph mean?
| A．sugar | B．ice | C．blood | D．molecule |
Stopping teens from smoking is a big challenge many communities face today. Many communities can only watch without being able to act while local businesses continue to sell tobacco products to children, even under the risk of punishment by law.
Recent studies show that a large percentage of teens today are getting their cigarettes from stores, mostly gas stations or convenience stores. As teens continue to be able to buy their own cigarettes, more and more communities begin to punish those who sell cigarettes to the teens.
One community has experienced success in their attempts to stop the sale of tobacco products to children. Woodridge, Illinois, started a program seven years ago which forbade and strictly punished the sale of tobacco products to children. The entire program includes local licensing of vendors (小贩), repeated undercover inspections to see if the sale to children has stopped, and education programs in schools. Woodridge has become a model community as other communities are moving to stop teen tobacco use.
A recent national study showed that 36.5% of females, and 40.8% of males buy their cigarettes from stores, whether it is a gas station or a supermarket. Hopefully, as more and more sellers see the trouble they face if caught selling to children, they will stop selling.
True, tightening down on stores that sell tobacco to children isn’t going to completely stop the problem of teen tobacco use. Teens continue to get them from other sources. But it definitely does prevent their efforts. With more education in schools, and perhaps stronger punishments for teens caught with tobacco, more and more teens will see the problems with the tobacco usage, and will stop the habit.To stop teens from smoking, more and more communities are ________.
| A．punishing those who sell cigarettes to teens more severely |
| B．punishing teens caught with tobacco more severely |
| C．educating those who sell cigarettes about the danger of teen smoking |
| D．stopping the sale of tobacco products in stores |
Which of the following is NOT a way Woodridge uses to stop tobacco sale to children?
| A．Local licensing to tobacco sale. | B．Repeated undercover inspections. |
| C．Education programs in schools. | D．Stronger punishment of teens caught smoking. |
It can be inferred from the passage that ________.
| A．teens can only buy cigarettes from gas stations and convenience stores |
| B．more communities have succeeded in stopping teen tobacco use |
| C．More males than females have the habit of smoking in America |
| D．Punishment alone cannot solve the problem of teen tobacco use |
What attitude does the writer have towards stopping teen tobacco abuse?
| A．Negative | B．Optimistic | C．Uncertain | D．Uncaring |
Recently there was a major discovery in the scientific research — the mapping of all DNA in a human gene(基因) is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument, in terms of morality(道德) or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations, then the other clone would be as well. The latter could be inserted in the woman and allowed to ripen to term. Moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle” of life. There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
Scientists haven’t 100% guaranteed that the first cloned humans will be normal. Thus, this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades” of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable. Which of the following is true according to the passage？
| A．Genetic limitation will be beneficial for some women |
| B．A large number of genes will prevent us from developing |
| C．Prohibition(禁止) of cloning might limit the freedom of scientists |
| D．First cloned humans might be normal according to scientists |
What’s the author’s opinion on cloning?
| A．Cloning should be entirely banned |
| B．Cloning should be used in creating life |
| C．Cloning will take away the right to reproduce |
| D．Cloning is acceptable if it is used for cloning organs |
Which of the following shows the structure of the passage
Why does a large education nation like China have so few world renowned scientists as the US? Educationists from China and the US try to find out the answer to questions like this at a forum on the basic education strategy.
The forum, held recently, was jointly organized by the Education Development Research Center of the Ministry of Education in China and the Postgraduate School of the University of Pennsylvania in the US. It aims to find out similarities and differences that exist between two countries in their educational system.
While some educationists in China keep a doubtful eye to the country’s educational system in recent years. Their American counterparts give a positive answer to the basic education in China, saying that it is still one of the best in the world.
An American educationist told reporters that the basic education in the US was criticized in recent years due to its political tendency. On the contrary, Chinese government’s stress on basic education and qualified teachers has set a good example.
At primary and middle school, pupils in China did better in math and science lessons than the US pupils. However, few grow to be world “masters”. Why? Educationists attributed this to China’s stress on examination rather than students’ interest.
Deputy Director of the postgraduate school of Pennsylvania University said American teachers encouraged students to focus on their strong points. In China, students are driven to study to pass the entrance examination test and they do not pay much attention to their own interest.
At the forum, director of the Education Development Research Center Mr. Zhang said in the future, the research center would make its middle and long-term basic education strategy by taking some references from other countries including the US.
He also revealed that for a long time in the future, China would make a breakthrough in setting the policy for quality education.This passage is mainly about _________.
| A．quality education development in the future |
| B．why China’s education cultivates(培养) few world masters |
| C．China’s good basic education |
| D．genius education at the primary stage |
The underlined word “renowned” in the first paragraph probably means ________
| A．famous | B．active | C．qualified | D．experienced |
Few pupils in China who did better in math and science lessons than the US pupils grow to be
world “masters”, because _________
| A．The US government spends more money on basic education |
| B．American pupils are cleverer than Chinese pupils |
| C．basic education in China is not as successful as that of the US |
| D．Chinese people pay less attention to students’ interest |
China’s educational system will _______ in the future.
| A．help students to study even harder to pass the examination |
| B．apply more attention to quality education referring to systems of other countries |
| C．allow students to pay more attention to their own interest without their test results |
| D．copy the educational system in the US |
The first and best of victories is for a man to conquer(征服) himself; to be conquered by himself is, of all things, the most shameful, says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses (冲动) and feelings, and from that moment he gives up his moral freedom.
A single angry word has lost many a friend. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. Whom the gods would destroy they first make mad. Keep cool, says George Herbert, for fierceness (狂怒) makes error a fault.
To be angry with a weak man is to prove that you are not strong yourself. Anger, says Pythagoras, brings with folly(愚蠢)and ends with regret. You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Self-control is man’s last greatest victory.
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking also.What does the reader learn from the first paragraph?
| A．The greatest victory for a man is to conquer everything except himself. |
