Children are being indirectly affectly by the impact of the recession (经济衰退) on their parents, the Children’s society warns.
The chief executive of the Children’s Society, Bob Reitemeier, said that children were “on the front of recession”. He said the recession made it even more important to try to end child poverty.
The answers suggest children from poorer backgrounds are more likely to be affected, but over a third of children across all backgrounds said they were aware that the recession was worrying their parents.
Fifteen-year-old Patricia said her family felt the impact of the recession on their everyday budget(预算). “We have to save up our money and do not spend it so much on unnecessary things,”she said.
Those questioned appeared to have great awareness of the economic crisis, which, unsurprisingly, was higher among the older children. But around 15% said they hadn’t been affected by it.
Recent figures showed that in 2007 there were 850,000 young people with no particular occupation. An official from the government said it was so “disappointing” that some young people were concerned about the economy.
Parents are clearly best placed to talk to their children about their worries, but schools also play an important role in teaching young people the skills they need to become healthy, happy and confident individuals.
( )68.Which of the following is true?
A. It is more important to try to end child poverty in the recession.
B.Children from poorer areas are less likely to be affected.
C.All the children questioned are worried about the economy.
D.That some young people are worrying about the economy is “good news”.
( )69.What does the underlined word “it” refer to in Paragraph 5?
A. The poorer background. B.The impact of the recession.
C. Everyday budget. D.The government.
( )70.What’s the main idea of the passage?
A. Many children are concerned about the recession.
B.Children are being directly affected by the recession.
C.The recession affected children indirectly.
D. Schools play an important role in teaching young people how to become healthy, happy and confident individuals. |
More and more American parents, students, educators, political and business leaders have come to see the importance of Chinese on the world stage. As a result, Americans hoping to learn Chinese are growing in number though they face a lot of difficulties.
Liu Chuansheng, chairperson of the University Council at Beijing Normal University, talked about this situation. “There have been 300 million Chinese learning English, and I know that there are more and more Americans beginning to learn Chinese. I remember when I came to the U. S. there were only 250 schools offering Chinese classes; when I left in 2005, there were already 2,400 schools hoping to offer Chinese classes. Today more than 700 schools are offering Chinese classes, and 4,500 are planning to do so.”
“This is an important time in America. We have suffered from an economic crisis; there is swine flu(猪流感) ---- all part of our lives. We need to be competitive to deal with the world and make an effort to understand each other,” said Shuhan Wang, head of Chinese Language Initiatives at Asia Society. “The number of Chinese language teachers remains the key bottleneck,” she said. “And the need for specialized teachers becomes greater, as there is increasing popularity of early language learning ---- kindergarten through 8th grades.”
Jon M. Huntsman Jr., governor(州长) of Utah, has led his state to the front in teaching Chinese. “While math and science remain main studies,” he said, “language is going to be an important drive in education. Next year 82 schools will offer Chinese to 6,000 students.”
64. It is implied in the passage that the number of Americans learning Chinese is growing mainly because _______.
A. more and more Americans face a lot of difficulties
B. the number of Chinese learning English is growing
C. Chinese is widely used by actors all over the world
D. China is playing a more important role in the world
65. Liu Chuansheng’s talk mainly shows us _______.
A. how Americans are learning Chinese B. why Americans are learning Chinese
C. that Chinese becomes popular in America D. that China offers more Chinese classes there
66. The biggest problem with Americans learning Chinese is that _____.
A. the Chinese language is too difficult for them to learn
B. they don’t have enough teachers of Chinese in the USA
C. American children are not good at learning languages
D. teachers won’t work in kindergartens or primary schools
67. The proper title for the passage is _______.
A. Americans show great interest in learning Chinese
B. Americans show less interest in math and science
C. Chinese teachers get new chance to work in America
D. Chinese is widely used in some states of America |
Winter is dangerous for drivers because it’s so difficult to know what is going to happen and accidents take place easily. Bad weather can be waiting to meet you. Ice might be hiding under the snow, waiting to send you off the road. The car coming towards you might suddenly move across the road. Here are two rules for driving safely on icy roads:
Rule Number One is to drive smoothly. Irregular movements can make a car very difficult to manage. So each time you either turn the wheel, touch the brake or increase your speed, you must be as gentle and slow as possible. Just imagine you are driving with a full cup of hot coffee on the seat next to you. You should drive carefully enough in order that you wouldn’t get the coffee out of the cup.
Rule Number Two is to pay attention to what might happen. The more ice there is, the farther you have to look down the road. Test how long it takes to stop by gently braking. Remember that you may be driving more quickly than you think. Generally speaking, allow double your normal stopping distance when the road is wet, three times this distance on snow, and even more on ice. Try to stay in control of your car at all times, or you will get into trouble.
49. Driving in winter is dangerous because _________.
A. drivers usually have too much coffee B. people drive three times faster than usual
C. unexpected things may often happen D. people drive more gently and slowly
50.Rule Number One mainly tells us _________.
A. to drive fast on snowy roads B. to increase the driving speed
C. to manage your car irregularly D. to drive smoothly on icy roads
51.Which of the following can be the best title of the passage?
A. Winter Driving B. Careless Driving C. Traffic Accidents D. Bad Weather
52.Where do you think you might read such a passage?
A. In dictionaries. B. In cookbooks. C. In advertisements. D. In magazines. |
The damming of river systems in the northwestern United States has had damaging effects on salmon(鲑鱼). In the spring young salmon, called smolts, drift into rivers from smaller streams. They swim with the current downstream heading for the Pacific Ocean. Before the large-scale constructions of dams(水坝), the young salmon used the strong flow from melting snows to get to the sea in between six and twenty days. It is necessary to do this because during these days the smolts’ bodies undergo the physiological changes for adaptation to salt water.
Unfortunately, the current has become very slow due to the construction of numerous dams. Companies operating the dams also intentionally slow the current. They store the water from the melting snow until the winter, when more electric power is needed. The net result is that many of the young fish do not survive the now sixty-day trip to the sea. Consequently, there are fewer adult salmon to migrate(回游) back up the rivers for breeding. When the time comes for the salmon to return, they again face the problem of dams. As fewer adult salmon are able to get back to their cool upstream water, they fail to produce a sufficiently new generation of salmon. This cycle could eventually lead to the extinction of the fish.
Attempts are being made to transport the young salmon down river by boats. However, many scientists think that this artificial method of getting the fish to the sea kills more than it saves. Another suggestion, recently proposed by environmentalists, is to increase the rate of water flow. This would be a partial（部分的） solution to the declining salmon numbers. One method of doing this would call for releasing water from upstream dam. This would speed up the downstream movement of the smolts.
Another method would be to reduce the water level in the dams for a period in the spring when the smolts are migrating downstream. This would also increase the flow rate temporarily without requiring large amounts of water and, thus, enable the young salmon to move downstream faster. Unfortunately, both of these proposals have met with criticism from the power companies, which strongly suggests the uncertain fate of the salmon in the region.
76. What’s the main topic of the passage?
A. The failure of adult salmon to reproduce.
B. The importance of smolts returning upstream.
C. The need for smolts to reach salt water quickly.
D. The harm caused to salmon by river damming.
77. The passage discusses all of the following methods of dealing with salmon issue EXCEPT _____.
A. carrying the fish in boats
B. allowing water to be released from upstream dams
C. dropping water levels in dams
D. breeding salmon
78. In paragraph 3, what does the author mean by the statement that many scientists think that this artificial method of getting the fish to the sea kills more than it saves?
A. Saving fish is artificial.
B. More fish die when transported than would die otherwise
C. Artificial methods of transportation give salmon the chance to get adapted to salt water.
D. The sea kills more fish than are saved by transportation.
79. Which of the following statements would the author most probably agree with?
A. The salmon problem is likely to continue.
B. A solution to the salmon problem will be found in the near future.
C. Salmon will be extinct very quickly.
D. The government should step in and provide a way out. |

At first, the earth’s surface layer (层 ) was made up of huge blocks of hard, solid rocks.There slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebble(卵石) and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remain mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil.
There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layer of the rock are slowly worn away. These leave holes and crack(裂缝) in the rock, which become bigger and finally the rock breaks up into smaller pieces.
The moving water of streams and rivers also help to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones, Thus, the larger rocks are worn down to smaller pieces.
The heat of the sun also help to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and cracks become wider, and finally break into smaller pieces.

A. forms very slowly
B. is a mixture of stones, pebbles and sand

3. Which of the following speeds up the breaks of rocks most ?
A. Hot weather B. Cold water
C. Sharp changs in temperature D. More dead plants in the cracks
4. Which of the following is NOT true ?
A.The remains of many plants of animals formed soil.
B. If a large rock never moves, it will never break up.
C.Even if a large rock never moves, it will break up.
D. Ice in the cracks helps to break up rocks.
5. The best titl for this passage should be ________ .
