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 (顆粒)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

"Hey, don't read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. “Don’t read in poor light!” This is one of the common beliefs that are supposed to help us live a healthy life. Such beliefs are, however, without scientific basis(根據(jù)), according to a paper published recently in the British Medical Journal.
Do you believe in the following sayings?
Reading in poor light ruins your eyesight.
In poor light, you might blink (眨眼) more, suffer from drying and have trouble focusing. But most of eye experts believe it is unlikely to do any damage forever.
We must drink at least eight glasses of water a day.
In 1945, the Nutrition Council in US suggested that people need to drink 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total.
We only use 10 percent of our brains.
This idea appears as early as 1907. People have long argued about our power of self-improvement and our brains’ possible abilities. But X-rays show that no area of the brain is silent or inactive.
Shaving your legs causes hair to grow black faster and thicker.
This theory is also illusion. Studies say that shaving has no effect on the thickness or rate of hair growth. Just over time, the edge of hair gets worn away and thus the edge of long hair becomes finer (更細(xì)).
1.What does the paper say about some common beliefs?
A. They are useful knowledge in life.
B. They help us live in healthy ways.
C. They are well-known theories.
D. They do not have scientific basis.
2.Which of the following is TRUE according to the passage ?
A. People use 90 percent of their brains.
B. Shaving your legs will give you thicker hair.
C. Reading in poor light does harm to people’s eyes.
D. People need not less than eight glasses of water a day.
3.The underlined word “illusion” in the last paragraph probably means “_________”.
A. a wrong idea B. a powerful evidence
C. an interesting story D. a clear instruction
4.This passage is most likely to be found in __________ .
A. a newspaper B. a guide book
C. a history textbook D. an advertisement

閱讀下列三篇短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項,并在答題卡上將該項涂黑。
It is important for Americans to thank other people for favors even if what the other person did was very small. Both children and older people should be thanked for any kind act. The person accepting the thanks usually says something to make the favor seem small, or says that it was his pleasure to help you, or simply, “ You’re welcome.”
It is equally important to apologize when you have hurt or disappointed someone. When possible, you should always add a reasonable explanation or excuse for your behavior. When there is some loss or damage to personal property(財產(chǎn)), the person responsible(負(fù)責(zé)) for the loss should both apologize and offer to pay for the item.
Most of the time the other person accepts the apology graciously and doesn’t show any disappointment or anger. But if the problem was really serious or it happened several times before, the person might say something how he feels.
56. It is necessary to thank a person who is _____ for any kind act.
A. older than you B. younger than you
C. the same age as you D. all of the above

say how sorry you feel and offer to pay for the item.

Say nothing and try to forget about it.
Pay for the damage without saying a word.
58. When you apologize for something, you should ____.
always remember to say it is not your fault.
try to explain the reason for your actions.
add an excuse even if it is not a good one.
none of the above
59.When someone apologizes to you, you should_____.
