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.

We’re a nation — a globe, in fact — obsessed with our hair. Analysts estimate the global hair product industry to be worth €22.6 billion, growing at a rate of up to seven percent a year.

There seems to be no limit on what we’ll spend to avoid a bad hair day. But for devotees of an underground beauty movement, the secret lies in throwing away the shampoo, in fact all the hair products, for good.

The “no-poo” method, which involves using natural substitutes or just water in place of shampoo and conditioner, is supported by several circles.

Beauty insiders, including writers for women’s magazines and professional hairdressers, speak highly of how hair becomes thicker, fuller, softer and brighter.

And environmentalists who are mindful of money feel great joy at the lack of chemicals in and on their bodies—not to mention the impact on their budgets.

Now one devotee is hoping to take it mainstream. Lucy Aitken Read, whose book Happy Hair: The definitive guide to giving up shampoo was released last week, hasn’t used shampoo for two years and her glowing brown hair is visibly in perfect condition.

For her, the motivation came after reading a study that claimed women put 515 chemicals on their bodies daily. “I initially thought ‘Ha! They didn’t research me!’,” Aitken Read says. “Then I looked at the back of my shampoo bottle and realized there were loads of chemical components I didn’t recognize in the slightest.”

Strangely it’s oily hair that could benefit the most from giving up shampoo. The theory behind the “no-poo” method is that shampoo removes the hair from its natural oils, which causes the scalp (头皮) to generate more oils to replace them. This results in oil overload — oily hair—which we then attempt to “fix” with more shampoo. It’s a vicious (恶性的) circle and quite a brilliant success for the shampoo industry, because the more shampoo you use, the more you need to use and the more frequently you need to use it.

Left to its own devices or washed with natural substitutes, the scalp eventually theoretically returns to its natural balance. The result should be healthier hair that is stronger, thicker and fuller as it is less damaged than shampooed hair.

1.What can we know from the first paragraph?

A. More and more people produce hair products.

B. More and more people waste money on their hair.

C. More and more hair products are wasted every year.

D. More and more hair products are produced every year.

2.According to Para 5, environmentalists are in favor of “no-poo” method because _______.

A. it has the same chemicals as shampoo does

B. it helps reduce their budgets on daily expenses in a way

C. natural substitutes are friendly to the environment

D. they know shampoo has an impact on their health

3.What can we learn from Lucy’s words?

A. She didn’t realize shampoo contains so many harmful chemicals.

B. She didn’t realize shampoo contains all the necessary chemicals.

C. She couldn’t recognize the description on the shampoo bottle.

D. She didn’t recognize she was quite different from other women.

4.What is the main trouble with shampoo?

A. It adds more oils to the hair.

B. It prevents the scalp producing oils.

C. It badly impacts the shampoo industry.

D. It makes people addicted to using it more often.

Technology has become so advanced that the previously impossible seems to occur on a daily basis. And yet — we still have no cure for the common cold.

According to Peter Barlow, a scientist at Edinburgh Napier University in the UK, the main challenge lies in the many different types of cold viruses. There are at least 160 types. They changed so easily that they quickly become resistant to drugs, or learn to hide from our immune systems. In other words, a single cure isn’t likely to work on every type of cold.

However, researchers from Stanford University have found a possible answer. They discovered a protein that the viruses need. Without it, they can’t spread inside your body. To　 identify the gene(基因) which produces the specific protein needed by the viruses, researchers used a gene-editing technique to test all genes. These modified (改变的) cells were then exposed to a range of viruses, including ones causing the common cold. All the viruses were unable to replicate (复制) inside cells without a gene that produces that specific protein.

Then, they tested genetically modified mice, which were completely unable to produce the protein. The mice were able to live normal lives without the protein. “Lacking that gene protected the mice completely from viral infection,” associate professor Jan Carette, from Stanford, told the BBC. “These mice would always die, but they lived through and we saw a very strong reduction in copying viruses and very strong protection. We have identified a fantastic target that all cold viruses require and depend on. Take that away and the virus really has no chance. ”

Carette said the plan is to find a drug which can temporarily control the protein, instead of producing genetically modified humans.

1.Which of the following can best describe common cold viruses?

A.Severe and deadly. B.Mysterious and stubborn.

C.Diverse and changeable. D.Challenging and oversized.

2.How does the protein work?

A.Help viruses spread. B.Reduce physical infection.

C.Fight against other viruses. D.Strengthen the immune system.

3.What can we learn about the genetically modified mice?

A.They caught cold easily. B.Their health worsened.

C.They produced more protein. D.They were able to survive,

4.What is purpose of the research?

A.To control certain genes. B.To conquer the common cold.

C.To test a new drug. D.To cure genetically modified mice.

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
