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

A.common         B.indirect
C.secondary D.leading

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.

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

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

A.Negative. B.Supportive.
C.Doubtful. D.Uninterested.

As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.
When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.
There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.
1. The author says that the world population is increasing because _____.
A. there are many rich valleys and large fields
B. farmers are producing more crops than before
C. people are living longer due to better living conditions
D. new lands are being made into farmlands
2. The author says that in areas with large populations, land might be more productively farmed if _____.
A. the land was divided into smaller pieces
B. people moved into the countryside
C. industrial methods were used in farming
D. the units of land were much larger
3. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.
A. growing new types of crops
B. irrigation and dry-farming means
C. providing fertilizers
D. destroying pests and diseases
4. Why is the land divided into tiny units in some areas?
A. There are too many people living there.
B. It saves more natural resources there.
C. It prevents crops from serious diseases there.
D. Farmers can grow various kinds of crops there.
5. Why do some people use dams to hold back waters from great rivers?
A. To develop a new kind of dry-farming methods.
B. To prevent crops from floods.
C. To provide water and electricity in all seasons.
D. To water poor lands in bad weather.

Most shops in Britain open at 9:00 am, and close at 5:00 or 5:30 in the evening. Small shops usually close for an hour at lunchtime. On one or two days a week—usually Thursday and/or Friday—some large food shops stay open until about 8:00 pm for late night shopping.
Many shops are closed in the afternoon on one day a week. The day is usually Wednesday or Thursday and it is a different day in different towns.
Nearly all shops are closed on Sundays. Newspaper shops are open in the morning, and sell sweets and cigarettes as well. But not all the things can be sold on Sundays.
Usually it is not difficult for foreign visitors to find where to buy things. Most shops sell the things that you want to buy. One problem is stamps. In Britain you can only buy these at post offices. Many large food shops are self-service. When you go into one of these shops, you take a basket and you put the things you wish to buy into this. You pay for everything just before you leave. If anyone tries to take things from a shop without paying they are almost certain to be caught, because most shops have detectives.
When you are waiting to be served in a shop, it is important not try to be served before people who arrive before you. Many foreign people are surprised at the British way of queuing (排队).

The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audience could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for ever. He sent camera team out one evening to film the sunset for him.
The next morning he said to the men, “Have you provided me with that sunset?”
“No, Sir,” the men answered.
The director was angry. “Why not?” he asked.
“Well,” one of the men answered, “we are on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”
“But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one.”
But then a young secretary had an idea. “Why don’t you photograph a sunrise,” she suggested, “and then play it backwards, Then it’ll look like a sunset.” “That’s a very good idea!” the director said. Then he turned to the camera team and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”
The camera team went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o’clock they took it to the director. “Here it is, Sir,” they said, and give it to him. He was very pleased.
