With the advance of human society, along with the development of modern science and technology, people are faced with an increasing number of pollutions. One of the severe pollutions is noise pollution. Many parents express their complaints over noise pollution, especially car alarms.

Anchor

Almost anyone who has lived in a big city can tell you how irritating it is to be awakened in the middle of the night by the wail of a car alarm. The loss of sleep can drive you crazy, but this is just one in a long list of problems that such high decibel noises can cause.

Jonathan

People in this noisy neighborhood in upper Manhattan are fed up with car alarms. They're angry enough at being jolted awake several times a week, but more than that they worry about what effect these alarms will have on their children. Already studies have shown that continuous exposure to high-decibel noise can cause an increase in heart rate and blood pressure.

Andrea

By the time my child can read, he will already have been exposed to the constant roar of the traffic, but the intense siren of a car alarm is way above the level of safety.

Michael

I have a valid concern. According to the National Institute of Occupational Safety and Health (NIOSH), exposure to noise above 85 decibels for 8 hours or more is a danger to your health. City traffic and trucks are about 90 decibels. The siren of a car alarm is about 120 decibels, about the same as a plane taking off.

The parents here are sick and tired of listening to the shrill siren of car alarms. However, it's for their children that they are most concerned. They've started a group called Parents to Silence Car Alarms. They don't think that making the owner of a car pay a fine is enough. These parents have started a campaign to have car alarms banned.

1.According to the passage, which one of the following statements is true?

A. Anchor thinks the high decibel noises only causes the loss of sleep.

B. Jonathan holds the view that exposure to decibel noises can give rise to heart disease.

C. According to NIOSH, exposure to noise above 85 for 8 hours or more threatens people's health.

D. Andrea believes the intense siren of a car alarm is acceptable.

2.According to the passage, what is the parents' attitude towards car alarms?

A. Neutral. B. Critical. C. Favorable. D. Indifferent.

3.What is the main idea of the passage?

A. People in modern society is faced with noise pollution.

B. Anyone who lives in a big city is tired of car alarms.

C. A car alarm is out of control and beyond the level of safety.

D. Parents complain about car alarms, trying to fight against them.

Science and technology have advanced at such a rate that cloning has now become a reality. The possibility of cloning humans is a serious issue(争论点) and raises ethical(伦理的) questions. In my opinion, cloning is useful for research into cures for disease. However, I think that it needs to be approached with caution and carefully monitored by governments.

Research into cloning and stem(严格的) cell production is primarily aimed at finding new treatments for currently incurable illnesses. While this would improve the quality of life for many, not enough is understood about what effects cloning would have on the world in the future. This is primarily because we do not understand enough about the results of cloning and both the physical and psychological effects that it is likely to have on cloned humans and on the rest of the world. Furthermore, it is thought that a cloned human would be unlikely to survive birth and would suffer from complications(并发症) resulting from malformed(畸形) organs .

There are also serious ethical issues in danger. In essence(在本质上), those who are against cloning would argue that scientists have no right to play God and to interfere(干扰)with natural processes. Producing embryos for the purpose of harvesting stem cells for research presents important questions about the nature and status of the embryo being produced. It may also make us question whether throwing it away after use reduces the value we place on human life.

In conclusion, I do not agree that research into cloning using human embryos should continue. This is not only because it may reduce the value we place on human life, but also because not enough is known about the effects.　　 However, I do think that if there is a way to produce stem cells using cloning which does not put human life at risk, then governments should continue to support it.

1.What is the writer’s general opinion on cloning?

A. It is useful in every area of research.

B. It needs to be carefully controlled by governments.

C. It is useful for research into cures for disease if it is controlled.

D. It is only useful for research into cures for disease.

2.The underlined word “approach” in the first paragraph means “______”

A. reach a high level or amount　　 B. move forward

C. come near　　 D. deal with

3.The writer’s main reason against cloning is that ______.

A. not enough is known about the effects of cloning

B. a cloned human would be likely to die of malformed organs

C. cloning has negative physical and psychological effects on clones

D. it would affect the quality of life for many

4.In the last paragraph, the writer thinks governments should______

A. not put human life at risk

B. support all forms of research into stern cell production

C. not support any form of research into stern cell production

D. support research into stern cell production harmless to humans life

Technology has totally transformed our ability to communicate with each other. Linking to each other both literally and figuratively, many of us connect through cell phones, email, instant messaging, blogs, and networking web sites, yet we may be less connected to each other than we think.

According to a study, Americans are becoming increasingly socially isolated(孤立的). The study suggests, for example, that one quarter of Americans say that they have no one to discuss important personal issues with, and that the number of close friends that Americans have has dropped from three to two. Meanwhile, the Boston Globe reports that this spreading isolation is experienced more sharply among those with less education, people of color, and older Americans. Unsurprisingly, those who are young, white, and well educated tend to have stronger social networks.

From my own experience I have to say that I’ve never felt more connected, thanks to a web of friends, family, and colleagues. One of my closest friends is someone I met through an online discussion group who lives hundreds of miles away from me. We have met face-to-face only twice, yet our regular electronic correspondence and cell phone calls maintain our close friendship. And, speaking of blogging, my blog has introduced me to people I would never have met otherwise and has led to enduring and important friendships.

On the other hand, I recently saw a scene unfold that proved to me how deeply disconnected we as Americans have become. I had just wrapped up a presentation on mediation at a family therapy (治疗) center.

As I was leaving, I noticed a mother and her teenage son who had just completed their session with their family therapist. After making their next appointment, they both took out their cell phones, placed calls, and began loud conversations with whoever was on the other end. I walked out behind them to the parking lot to my car. They both jumped into their cars, and, as I saw them drive off, they were still talking on their cell phones but not to each other.

1.What does the passage lead you to believe?

A．Americans are more socially isolated today.

B．Americans are more socially connected today.

C．Americans don’t make good use of technology.

D．Technology plays a bigger role in American society.

2.Which of the following has nothing to do with the isolation among Americans?

A．Sex.              B．Education.         C．Skin color.         D．Age.

3.What is true about the mother and son in the passage?

A．They came for therapy in the same car.

B．They were quite close to each other.

C．There was not much communication between them.

D．They preferred talking to each other on cell phones.

4.What can we learn from the passage?

A．The writer is totally against the modern technology.

B．The mother and the son have finished their family therapist and get a better relationship.

C．As far as the writer is concerned, he has benefited a lot from the modern technology.

D．Those black and well-educated people have stronger social network than aged white people.
