I travel a lot, and I find out different “styles” of directions every time I ask “How can I get to the post office?”

Foreign tourists are often confused in Japan because most streets there don’t have names; in Japan, people use landmarks (地標) in their directions instead of street names. For example, the Japanese will say to travelers, “Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop.”

In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, “Go north two miles. Turn east, and then go another mile.”

People in Los Angeles, California, have no idea of distance on the map; they measure distance in time, not miles. “How far away is the post office?” you ask. “Oh,” they answer, “it’s about five minutes from here.” You say, “Yes, but how many miles away is it?” They don’t know.

It’s true that a person doesn’t know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, ‘Sorry, I have no idea.” But in Yucatan, Mexico, no one answers “I don’t know.” People in Yucatan believe that “I don’t know” is impolite, They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!

1.When a tourist asks the Japanese the way to a certain place they usually _________

A. describe the place carefully

B. show him a map of the place

C. tell him the names of the streets

D. refer to recognizable buildings and places

2.What is the place where people measure distance in time?

A. New York. B. Los Angeles. C. Kansas. D. Iowa.

3.People in Yucatan may give a tourist a wrong answer ________

A. in order to save time B. as a test C. so as to be polite D. for fun

4.What can we infer from the text?

A. It’s important for travelers to understand cultural differences.

B. It’s useful for travelers to know how to ask the way properly.

C. People have similar understandings of politeness.

D. New Yorkers are generally friendly to visitors.

科目:高中英語 來源:2016屆上海市高一下學期期末英語試卷(解析版) 題型:閱讀理解

In modern society there is a great deal of argument about competition. Some value it highly, believing that it is responsible for social progress and prosperity; others say that competition is bad; that it sets one person against another; that it leads to unfriendly relationship between people.

I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit of success, the development of many other human qualities is sadly forgotten.

However, while some seem to be lost in the desire to succeed, others take an opposite attitude. In a culture which values only the winner and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse: “I may have lost, but it doesn’t matter because I really didn’t try.” What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of the true competitors who try to prove themselves. Both are based on the mistaken belief that one’s self-respect relies on how well one performs in comparison with others. Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve can we discover a new meaning in competition.

1.What does this passage mainly talk about?

A.Competition helps to set up self-respect.

B.Opinions about competition are different among people.

C.Competition is harmful to personal quality development.

D.Failures are necessary experiences in competition

2.Why do some people favor competition according to the passage?

A.It pushes society forward.

B.It builds up a sense of duty.

C.It improves personal abilities.

D.It encourages individual efforts.

3.What is the similar belief of the true competitors and those with a desire to fail ?

A.One’s worth lies in his performance compared with others.

B.One’s success in competition needs great efforts.

C.One’s achievement is determined by his particular skills.

D.One’s success is based on how hard he has tried.

4.Which point of view may the author agree to?

A.Every effort should be paid back.

B.Competition should be encouraged.

C.Winning should be a life-and-death matter.

D.Fear of failure should be removed in competition.

We sometimes think global warming or climate change is a problem very far away from our lives, and that only the government needs to worry about it. But it's hardly possible to completely stay out of it ­ scientists are now 95 percent sure that humans have been the “dominant cause” of global warming trends since the 1950s.

One of the conclusions of a report released on Sept 27 by the United Nations says that human activities have caused global temperatures to rise by 0.89 0C between 1901 and 2012. That might not seem like a lot, but the truth is that a major part of that heat has been absorbed into the oceans, which is not surprising given that they cover two thirds of Earth's surface. Also, water has a much greater capacity (容量) to absorb heat than the air does, according to The Economist. 

While many greenhouse gases occur naturally and are needed to keep the Earth warm enough to support life, humans' use of fossil fuels is the main source of excess (多余的) greenhouse gases. According to CNN, by driving cars, using electricity produced by burning coal and oil or heating our homes with coal or natural gas, we release a large amount of greenhouse gases into the atmosphere.

Your body can barely feel a difference of 0.89 0C, but the Earth's ecosystems are so sensitive that even small changes can disturb them. It often starts with the smallest creatures at the bottom of the food chain, eventually affecting bigger animals, many of which could end up becoming extinct.

Global warming is also linked to an increase in extreme weather. A larger amount of carbon dioxide traps more energy inside the atmosphere. This changes the patterns of storms and rainfall in many regions and can lead to droughts and floods. Worse still, melting sea ice in warmer oceans is causing sea levels to rise at a speed of more than three millimeters per year, according to The Guardian, which also increases the risk of flooding.

“The report should serve as another wake­up call that our activities today have a profound impact on society, not only for us, but for many generations to come,” French Michel Jarraud, secretary­general of the World Meteorological Organization, said at a news conference.

1.The underlined word “dominant” in the first paragraph means “ ________”.

A. common        B.indirect

C.secondary D.leading

2.Which of the following statements is TRUE according to the passage?

A.Greenhouse gases have been proven to harm merely the Earth .

B.There is little we can do to prevent global warming.

C.Global warming can increase the chances of droughts and floods.

D.The hugeness of oceans makes them better absorbers of heat than the air.

3.The rise in global temperatures between 1901 and 2012 ________.

A.is more harmful to smaller creatures than bigger ones

B.is not serious because most of the extra heat has been absorbed by the oceans

C.has made the Earth's ecosystems more sensitive to changes

D.is likely to cause many species to become extinct

4.What is Michel Jarraud's attitude toward the report released by the UN?

A.Negative. B.Supportive.

C.Doubtful. D.Uninterested.

● 2. In order to succeed, children need to feel they’re good at something. So expose your children to as many interests as possible, and then let them choose those they like best.

● 4. Making his/ her own decisions increases a child’s sense of control and builds his/ her self-esteem. And allowing kids to make wrong decisions so long as doing so won’t harm them helps kids learn from their mistakes.

A. Help them to find their talents.
