Insurance companies provide a service to the community by protecting it against expected and unexpected disasters. Before an insurance company will agree to insure anything, it collects accurate figures about the risk. It knows, for example, that the risk of a man being killed in a plane accident is less than the risk he takes in crossing a busy road. This enables it to quote(报价) low figures for travel insurance. Sometimes the risk may be high, as in motor-racing or mountaineering. Then the company charges a much higher price. If too many climbers have accidents, the price rises further. If the majority of climbers fall off mountains, the company will refuse to insure them.

An ordinary householder may wish to protect his home against fire or his property against burglary(入室行窃). A shopkeeper may wish to insure against theft. In normal cases, the company will check its statistics and quote a premium(保险费). If it is suspicious(可疑的), it may refuse to quote. If it insures a shop and then receives a suspicious claim, it will investigate the claim as a means of protecting itself against false claims. It is not unknown for a businessman in debt to burn down his own premises so that he can claim much money from his insurance company. He can be sure that the fire will be investigated most carefully. Insurance companies also accept insurance against shipwreck or disaster in the air. Planes and ships are very expensive, so a large premium is charged, but a reduction is given to companies with an accident-free record.

Every week, insurance companies receive premium payments from customers. These payments can form a very large total running into millions of dollars. The company does not leave the money in the bank. It invests (投资) in property, shares (股票) ,farms and even paintings and stamps. Its aim is to obtain the best possible return on its investment. This is not as greedy as it may seem since this is one way by which it can keep its premiums down and continue to make a profit while being of service to the community.

A super drug that could remove Alzheimer’s (老年痴呆症)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.

Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.

Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.

Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”

But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved.

Some people are able to live to 100 years because of ______.

A. a magical medicine B. three special genes C. good living habits D. longevity proteins

Why does the discovery of the longevity genes mean a lot?

A. Because it can bring great benefits to scientific labs.

B. Because it can help people change their unhealthy genes

C. Because it helps produce a drug that can make people live longer.

D. Because it will help scientists build up a new branch of biology.

From Paragraph 4 we can infer that ________.

A. longevity genes can create good cholesterol.

B. the volunteers share some common ancestors

C. bad habits are likely to have no effect on the volunteers

D. longevity genes protect the volunteers against bad habits

What is Andrew Ketteringham’s attitude toward the study?

A. Positive B. Negative C. Critical D. Cautious

If you look for a book as a present for a child, you will be spoiled for choice even in a year when there is no new Harry Potter. J.K. Rowling’s wizard is not alone: the past decade has been a harvest for good children’s books, which has set off a large quantity of films and in turn led to increased sales of classics such as The Lord of the Rings.

Yet despite that, reading is increasingly unpopular among children. According to statistics, in 1997 23% said they didn’t like reading at all. In 2003, 35% did. And around 6% of children leave primary school each year unable to read properly.

Maybe the decline is caused by the increasing availability of computer games. Maybe the books boom has affected only the top of the educational pile. Either way, Chancellor Gordon Brown plans to change things for the bottom of the class. In his pre-budget report, he announced the national project of Reading Recovery to help the children struggling most.

Reading Recovery is aimed at six-year-olds, who receive four months of individual daily half- hour classes with a specially trained teacher. An evaluation earlier this year reported that children on the scheme made 20 months’ progress in just one year, whereas similarly weak readers without special help made just five months’ progress, and so ended the year even further below the level expected for their age.

International research tends to find that when British children leave primary school they read well, but read less – often for fun than those elsewhere. Reading for fun matters because children who are keen on reading can expect lifelong pleasure and loving books is an excellent indicator of future educational success. According to the OECD, being a regular and enthusiastic reader is of great advantage.

Which of the following is true of Paragraph 1?

A. Many children’s books have been adapted from films.

B. Many high-quality children’s books have been published.

C. The sales of classics have led to the popularity of films.

D. The sales of presents for children have increased.

Statistics suggested that ___.

A. the number of top students increased with the use of computers.

B. a decreasing number of children showed interest in reading.

C. a minority of primary school children read properly.

D. a large percentage of children read regularly.

What do we know about Reading Recovery?

A. An education of it will be made sometime this year.

B. Weak readers on the project were the most hardworking.

C. It aims to train special teachers to help children with reading.

D. Children on the project showed noticeable progress in reading.

Reading for fun is important because book-loving children ____.

A. takes greater advantage of the project.

B. shows the potential to enjoy a long life.

C. is likely to succeed in their education.

D. would make excellent future researchers.

The aim of this text would probably be ____.

A. to overcome primary school pupils’ reading difficulty.

B. to encourage the publication of more children’s books.

C. to remind children of the importance of reading for fun.

D. to introduce a way to improve early childhood reading.

Julia，if you hurry up，I think it quite ______ that you will catch the next train.
