【题目】阅读下列短文，从每题所给的四个选项（A、B、C、和D）中，选出最佳选项。

To extinguish (熄灭) different kinds of fires, several types of fire extinguishers have been invented. They must be ready for immediate use when fire breaks out. Most portable (手提式的) kinds operate for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and planes to carry extinguishers.

Since fuel, oxygen and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material below a certain temperature, the fire goes out. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.

Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used to cover a small fire.

A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.

The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in three classes. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.

【1】If a fire breaks out on a bus, which of the follow should be ready there for you to use?

A. Sand. B. Water.

C. A blanket. D. An extinguisher.

【2】To cover a small piece of burning wood with a basin(盆) in order to stop the fire is an example of ________.

A. cutting off the oxygen B. reducing the heat

C. removing the fuel D. separating the fire

【3】In choosing how to put out a fire, we should first be clear about ________.

A. when it breaks out B. what kind it is

C. how it comes about D. where it takes place

【4】What would the author probably discuss in the paragraph that follows?

A. Another type of extinguishers B. Another class of fires

C. How fires break out. D. How fires can be prevented.

【答案】

【1】D

【2】A

【3】B

【4】B

【解析】

试题分析: 本文讲述了对不同的着火的类型要采用不同的灭火方法。

【1】D 细节理解题。根据第一段中The law requires ships, trains buses and planes to carry extinguishers.可知，在公共汽车上有灭火器，公共汽车上着火应该用灭火器，故D项。

【2】A 推理判断题。根据第三段中Another method of extinguishing fire is by cutting the oxygen. This is usually done by covering the fire with sand, steam or some other things.可知，用脸盆盖上烧着的木头显然是切断氧气的方法，故选A项。

【3】B 细节理解题。根据第五段第一句The method that is used to put out a fire depends upon the type of fire.可知，首先要弄清着火的类型，然后再想用什么方法扑灭，故选B项。

【4】B 推理判断题。根据最后一段讲了Fires have been grouped in three classes.以及讲述了第一种可知，所以后面很可能描述另外两种，故选B项。

【题目】阅读理解。

According to a new US study, couples who expect their children to help care for them in old age should hope they have daughters because they are likely to be twice as attentive overall.

The research by Angelina Grigoryeva, a sociologist at Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members.

Her analysis of the family networks of 26,000 older Americans concluded that gender(性别) is the most important predictor(预示物) of whether or not people will actively care for elderly parents.

In a paper being presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men statistically likely provide less care.

Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a cross-section of over-50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.

“Sons reduce their relative care-giving efforts when they have a sister, while daughters increase theirs when they have a brother.”

“This suggests that sons pass on parent care-giving responsibilities to their sisters.”

In the UK, the 2011 census(人口普查) showed that there are now around 6.5 million people with caring responsibilities, a figure which has risen by a tenth in a decade.

But many are doing so at the risk of their own health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a full-time job are three times more likely to be struggling with ill health than their working counterparts(相对应的人) who are not carers.

【1】In the text, what’s the most important factor to predict if people will actively care for the elderly?

A. Career. B. Education.

C. Gender. D. Family networks.

【2】The US study finds that _______.

A. sons are twice likely as daughters to care for parents in old age

B. having a sister makes men less likely to do their fair share

C. sons and daughters seem to give equal care to their parents

D. sons are unwilling to leave care-giving responsibilities to female family members

【3】What does the author stress in the last paragraph?

A. People should give up their jobs to care for the elderly.

B. Many care providers work longer hours than others.

C. People shouldn’t pass on caring responsibilities to others.

D. Many care providers have potential health problems.

【4】The author develops the text by _______.

A. analyzing various research and data

B. describing people’s experiences

C. explaining social networks of careers

D. comparing different gender behavior

【题目】阅读理解。

Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. “What could be causing everyone to act this way?”

Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real talk I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.

Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quite! How could I know that she meant that George Washington?

Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster’s office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet!

【1】What did the author’s classmates think about his report?

A. Controversial. B. Ridiculous.

C. Boring. D. Puzzling.

【2】Why was the author confused about the task?

A. He was unfamiliar with American history.

B. He followed the advice and flipped a coin.

C. He forgot his teacher’s instruction.

D. He was new at the school.

【3】The underlined word “burning” in Para. 3 probably means _______.

A. annoyed B. ashamed

C. ready D. eager

【4】In the end, the author turned things around _______.

A. by redoing his task

B. through his own efforts

C. with the help of his grandfather

D. under the guidance of his headmaster
