高二英语单项填空简单题查看答案及解析

The technique can lead to new ways to produce medicines, the researchers from the universities of Istanbul and Hawaii hope.

As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow(发光) in the dark.

Their efforts produced two rabbits out of a litter of eight that went from being a normal, fluffy white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of a collaboration（合作） between scientists from universities in Turkey and Hawaii.

The rabbits glow to show that a genetic manipulation technique can work efficiently, though the specific color is more cosmetic than scientific. "The green is not important at all – it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor Stefan Moisyadi.

To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Those altered embryos（胚胎）. Those altered embryos were then inserted back into the mother. Similar experiments have resulted in glowing cockroaches and cats.

Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said.　　 “The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that

can be cheaply extracted, especially in countries that can’t afford big pharma plants that make drugs, that usually cost $1bn to build, and be able to produce their own protein-based medication in animals," Moisyadi said.

The rabbits are expected to have the same life span as their non-glowing counterparts（副本）, but Moisyadi said he understands people can object to this kind of experimentation involving live animals.

"To the people against, I say: think about, what are the benefits and what are the injuries?" Moisyadi said. "And if the benefits outweigh the injuries, let's go with the benefits."

Moisyadi, a native of Turkey who is now with the University of Hawaii, started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.

1.Moisyadi’s attitude towards this kind of experiment is　　　　　　 .

A. doubtful.

B. indifferent.

C. supportive.

D. objective.

2.How did glowing effect produce?

A. It was just the result of genetic selection.

B. Put a light into a mother rabbit’s embryos.

C. Injected glowing cats DNA into a mother rabbit’s embryos.

D. Injected Jellyfish DNA into a mother rabbit’s embryos.

3.The final goal of this research is　　　　　　 .

A. To make animals cuter.

B. To make nights brighter.

C. To produce all kinds of glowing animals.

D. To produce beneficial molecules in animals’ milk.

4.What can we learn according to the passage?

A. The life span of glowing rabbits is much shorter than that of non-glowing ones.

B. The glowing rabbits were born only at the University pf Hawaii.

C. Scientists have created glowing cockroaches and cats before.

D. Three rabbits out of eight can glow in the experiment.

From the first use of the rocket to carry satellites into space to the setting up of space stations，human beings have achieved many successes.But there are still numerous tasks in front of us and we should not stop trying to progress.

The international space station is an important step we should take in space exploration.It is not only helpful but also necessary.It provides a proper space environment for many experiments that we have wanted to do for a long time.It is also a base for observing the earth and the universe.It could also be an important　 base for later travel to the moon and Mars.In a word，if we want to explore space more，the first thing we should do is to set up a space station.

As the space station costs a lot of money，it is hard for one country alone to establish one.The US seems to be the only country that has the ability to build a space station alone，and it has tried to do so，but not very successful.So it aggregated many other countries to work on it together.Though it is still extremely expensive，it is much cheaper than doing it alone.It is really a job that needs everyone’s effort and will benefit everyone.

But even so，the funds (资金) needed are still a big problem.As for the US，it seems that it has too many things to spend its money on.Although it is the richest country in the world，it has much debt every year.It has to try to find a balance in all these issues.

Throughout the world, clothing has many uses. It is used to provide protection from cold. It is also worn to prevent others from seeing specific parts of one’s body. However, the parts of the body that must be covered vary widely throughout the world. Some clothing is worn to provide supernatural protection. Wearing a lucky shirt to take an exam is calling for supernatural assistance.

People in all cultures use clothing and other forms of bodily decoration to communicate status(身份), intentions and other messages. In North America, we dress differently for business and various leisure activities. North American women usually are much more knowledgeable of little difference in messages communicated by clothes than men. At times, this leads to silly mistakes of understanding of female intentions on the part of men. Of course, clothing styles also are intended to communicate messages to members of the same gender（性别）.

Long before we are near enough to talk to someone, their appearance tells their gender, age, economic class, and often even intentions. We begin to recognize the important cultural clues at an early age. The vocabulary of dress that we learn includes not only items of clothing but also hairstyles, jewelry, and other body decoration. In most cultures, however, the same style of dress communicates different messages depending on the age, gender, and physical appearance of the individual wearing it.

Putting on certain types of clothing can change your behavior and the behavior of others towards you. This can be the case with a doctor’s white lab coat, or an army uniform. Most uniforms are clearly symbolic so that they can rapidly and unmistakably communicate status. For instance, the strange hairstyle and clothing of the English “punks” are essential aspects of their uniforms.

There are many forms of body decoration other than clothes that are used around the world to send messages. These include body and hair paint, and even body deformation. When doctors put braces on teeth, they are actually doing the same thing – deforming or reforming a part of the body to make it more attractive.

1.Which of the following is the best title for this passage?

A.　 Clothing and Culture

B.　 Ways of Sending Message

C.　 Clothing and Social Behavior

D.　 Communication through Clothing

2.Some people wear lucky shirts to take an exam because they believe 　　　　　 .

A.　 clothes can hide their fear for the exam

Ever since man began to use the telephone, there have been new problems arising from the carrying of messages. At first, each message was carried by a pair of overhead wires. As a result, telephone exchanges were soon surrounded by thousands of wires. The wires were then replaced by cables (电缆)，each containing many pairs of wires. Each cable is capable of carrying many messages. These cables, laid underground, replaced the overhead wires.

The more extensive telephone services have become, the more demand for these services has increased, particularly the demand for long-distance services. In China, for example, this growth is now over 30% every year. Long-distance telephone exchanges are usually in crowded cities, where is not easy to lay new labels for expanding services.

The use of radio to send telephone message and to link all telephone exchanges makes it possible to get rid of overhead wires and some underground cables.

Now man has invented the microwave system ( 微波系统 ). In a microwave system messages from various places can be brought together, and then they are sent out and received by radio. After that, the messages are split into their original form. Finally, they are sent to the places where they are going to be sent.

1.The word “message” ( in paragraph 1) is close in meaning to “______”.

A. electricity     B. industry     C. information    D. wave

2.A cable is different from an overhead wire, because it ________.

A. is made of wood

B. needs more exchange

C. carries more messages

D. is much longer

3.What does the word extensive mean？

A. growing       B. using       C. holding     D. understanding

4.The best title for the passage would be “________”.

A. The Telephone and Its Past

B. From the Wire to the Microwave System

C. The Needs for Better Telephones

D. How to Use the Telephone
