Each year, road accidents kill a million people and injure millions more . The economic costs are greatest for developing countries . Earlier this year , the United Nations called for a campaign to improve road safety .

One way to avoid accidents is better driving . Another is better roads and bridges . Engineers in the Unites States have designed ten new concrete mixtures that they think could make bridges last longer .

Professor Paul Tikalsky leads the experiments by a team at Pennsylvania State University . He says bridges made of concrete now last about twenty-five to thirty-five years . But he says the new mixtures might extend that to seventy –five or even one-hundred years .

Concrete is made of stone , sand , water and cement(水泥). The materials in the cement hold the concrete together . Ancient Romans built with concrete . Yet strengthened concrete bridges did not appear until the late 1800s . People keep looking for new ways to improve concrete . Professor Tikalsky says it is one of the most complex of all chemical systems .

The new mixtures designed by his team contain industrial waste products . He says these make the concrete better able to resist damage from water and salt over time . One of the products is fly ash . This is released into the air as pollution when coal is burned .

Professor Tikalsky says particles (颗粒)of fly ash are almost exactly the same size and chemical structure as Portland cement . This is the most costly material in concrete . So using fly ash to replace some of it would save money .

The federal government is paying for part of the research . Engineers anywhere can use the technology . Professor Tikalsky says some of the ideas have already been put to use in China , the Philippines and other countries .

Why did the United Nations launch the campaign ?

A. Because the United Nations wanted to reduce road accidents and economic costs

B. Because two million people were killed in the accidents .

C. Because engineers wanted to design ten new concrete mixtures .

D. Because the United Nations made bridges of the new mixtures which could last for about 20 to 35

years .

What does the underlined word “ this ” in the sixth paragraph refer to ?

A. Fly ash B. Portland cement C. Sand D. Chemical

Which of the following statements is TRUE ?

A. Ten new concrete bridges have already been built in the United States .

B. A new concrete bridge could last 50 more years than an ordinary concrete one .

C. People didn’t know how to build with cement until the late 1800s .

D. Water and salt won’t do any damage to bridges over time .

What does the passage mainly tell us ?

A. The causes of road accidents . B. The advantages of fly ash

C. The measures of avoiding road accidents D. Latest information about long-life concrete bridges

We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it’s hard not to wonder if the disease that comes from foreign animals is homing in on human beings. “Most of the infections (感染) we think of as human infections started in other animals, ” says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University.

It’s not just that we’re going to where the animals are, we’re also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen’s pets, and she now thinks that keeping foreign pets is a bad idea. “I don’t think it’s fair to have them as pets when we have such a limited knowledge of them,” says Isaksen.

“Laws allowing these animals to be brought in from deep forest areas without stricter control need changing,” says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But some strains (变异体) may become harmful. Monkey-pox doesn’t look a major infectious disease. But it is not impossible to pass the disease from person to person.

1．We learn from Paragraph 1 that the pet sold at the shop may

A．come from Columbia

B．prevent us from being infected

C．enjoy being with children

D．suffer from monkey-pox

2．Why did Isaksen advise people not to have foreign pets?

A．They attack human beings

B．We need to study native animals

C．They can’t live out of the rain forest

D．We do not know much about them yet

A．a new disease

B．a clear warning

C．a dangerous animal

D．a morning call

D. should stop buying pests from Africa

Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.

Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(释放)poisons that make people sick.

Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.

Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.

When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.

Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.

67. Which of the following statements is NOT true?

A. Food when poisoned can make people sick.

B. Food poisoning means death.

C. Food poisoning comes in varieties.

D. Food poisoning can be serious.

68. Food poisoning can be caused by all the following EXCEPT ________.

A. some chemicals B. low temperatures

C. some tiny living things D. certain natural materials

69. From Paragraph 5,we can learn that ______________.

A. mushrooms should not be eaten

B. vegetables are safer than meat and seafood

　　C. natural poisons are more dangerous than chemicals

　　D. different types of food should be handled differently

70. It can be inferred from the passage that____________ .
