B
Most parents love the Internet and want their kids to use it. But a new survey in America finds almost as many also fear the online world—especially social networking sites such as My Space—and worry their kids will get in trouble with people they meet.
“The parents see the web’s incredible potential(可能性), and they know their kids have to be there.” says James Steyer, CEO of Common Sense Media, which released results from a survey that looked into parental attitudes toward the Internet. “It is also what they are scared of most.”
The study was conducted online May 5-10 by Insight Research Group. It says 80% of parents are concerned about kids meeting bad people online. That’s because young people who largely have grown up with the Net think of it as a social outlet(出口), say the researchers. To young people, the benefits of giving out some personal information to reach out to friends outweigh the risks. And the study shows they are so comfortable with the medium that 78% have a personal website or blog.
Parents also recognize the importance of the Internet. The survey shows 91% think the Net helps their children explore their passions, and 77% think the Internet is one of the most valuable education tools teens have. But 88% think it’s important to know what their kids are doing online.
Findings suggest both parents and teens need more education about using online media, Steyer says.
Internet safety has become an increasing concern for parents in America. Organizations like the Non-profit Common Sense have been trying to reach and help parents pay attention to the problem. In the second paragraph, the underlined word “It” refers to_____.
| A．Common Sense Media | B．the result of the survey |
| C．the web’s incredible potential | D．the website called My Space |
Why do young people give out their personal information?
| A．They think it has more advantages than disadvantages. |
| B．They want to make themselves famous by doing that. |
| C．They want to have a personal website each. |
| D．They want to get some information from others. |
Most parents think it is important to know_____.
| A．where their children give out the information | B．what kind of websites they have |
| C．how often they go online | D．what their children are doing online |
From the passage we can infer that_____.
| A．children are too young to know how to use the Internet |
| B．parents must teach their children how to use the Internet |
| C．parents also need to learn more about using the Internet |
| D．the Internet is the most valuable tool for children to learn |
Most people think that the older you get, the harder it is to learn a new language. That is, they believe that children learn more easily and efficiently than adults. Thus, at some point in our lives, maybe around age 12 or 13, we lose the ability to learn languages well. Is this idea a fact or myth(悬念)？
Is it true that children learn a foreign language more efficiently than adults? On the contrary, research studies suggest that the opposite may be true. One report, on 2,000 Danish children studying Swedish, concluded that the teenagers learned more, in less time, than the younger children. Another report, on Americans learning Russian, showed a direct improvement of ability over the age range tested; that is, the ability to learn increased as the age increased, from childhood to adulthood.
There are several possible explanations for these findings. For one thing, adults know more about the world and therefore are able to understand meanings more easily than children. Moreover, adults can use logical(逻辑的) thinking to help themselves see patterns in the language. Finally, adults have more self-discipline (self-control) than children.
All in all, it seems that the common idea that children are better language learners than adults may not be a fact, but a myth.The main idea of the passage is ____.
| A．teenagers are more difficult to teach |
| B．Danish teenagers can learn Swedish faster than younger children |
| C．adults are more logical than children |
| D．the ability to learn languages increases with age |
According to the passage, teenagers can learn a foreign language _____ than younger children.
| A．harder | B．more efficiently |
| C．more slowly | D．more carefully |
Which of the following possible explanations for older student’s better achievement is not mentioned in the above passage?
| A．Adults know more about the world. | B．Adults can use logical thinking |
| C．Adults have more self-discipline. | D．Adults can read better. |
The porter(行李搬运工) brings your bags to your room and helpfully explains all you want to know．Then he points to the phone and says：“If there’s anything else you need, just call．”All this time you have been thinking of one thing：“How much should I tip(付小费)him?” To make your next trip a little easier, here’s guide to tipping across some Asian countries.
Bangkok(曼谷)
In general, the more westernized the place is, the more likely you will be expected to leave a tip．Some top-end restaurants will add a 10％ service charge to the bill．If not, waiters will appreciate your tacking on(附加)the 10％ yourself．However, if you’re eating at a lower-end restaurant, a tip is not necessary．If you’re staying at one of Bangkok’s many five-star hotels, expect to tip the porter 20 to 50 baht(泰国货币单位),depending on how many bags you have．Taxis are now metered in Bangkok．Local custom is to round up(凑整数)the fare to the nearest five baht．
Hong Kong
Tipping is customary in this money-mad metropolis(大都市)．Most restaurants add a 10％ service charge to the bill, but the extra money often ends up in the pocket of the owner. If the service is good, add another 10％ to the bill, up to HKMYMl00 in an especially nice restaurant．For HK MYM10 hotel porters should do it at all but the nicest hotels where a new HKMYM20 bill may be more acceptable．When in a taxi, round up to the nearest dollar．
Kuala Lumpur（吉隆坡）
Tipping in Malaysia is limited to the expensive westernized hotels, which often add a 10％ service charge to your meal or hotel room．If you are at a hotel restaurant, expect a 10％ service charge．
But at local restaurants, there’s no need to add a tip. At five-star hotels, one or two ringgit(马来西亚货币单位)will satisfy a porter. At lower-end buildings don’t feel you have to tip Like Bangkok, many taxis are now metered so you can just round up to the nearest ringgit．
Seoul
Tipping is not part of Korean culture, although it has become a matter of course in international hotels where a 10％ service charge is often added．If you’re at a Korean barbecue joint(烧烤处), there’s no need to add anything extra．But a nice Italian restaurant may require a 10％ contribution．
If you’re at a top-end hotel, so expect to pay 500～l,000 won per bag．Taxi drivers don’t accept a tip．Keep the change for yourself．Which of the following is NOT the unit of money?．
| A．Charge | B．Baht | C．Won | D．Ringgit |
In which of the following cities is it unnecessary to tip the taxi-drivers?
| A．Bangkok | B．Hongkong | C．Kuala Lumpur | D．Seoul |
If you stay at a five-star hotel in Kuala Lumpur, how much will you pay the porter at least?
| A．10％ of service charge | B．Three ringgit | C．Half a ringgit | D．One ringgit |
The writer seems．
| A．to tell the readers how to travel |
| B．to give the readers some advice on how to tip |
| C．to ask the readers to go on a travel to Asian cities |
| D．to make the trip more pleasant |
Here in Alaska, the wolf almost disappeared a few years ago, because hunters were killing hundreds of them for sport. However, laws were passed to protect the wolves from sportsmen and people who catch the animals for their fur. So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply.
A wolf naturally lives on animals in the deer family. People there also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the plant life there. When the deer can’t find enough food, they die.
If the wolves continue to kill large numbers of deer, the deer will disappear some day. And the wolves will, too. So we must change the life cycles there. If we killed more wolves, we would save them from starving. We also save deer and some farm animals.
In another northern state, wolves attack cows and chickens for food. Farmers want the United States government to send a team of scientists to study the problem. They believe it is necessary to kill wolves in some areas and to protect them in places where there is a small population.In Alaska, laws have been passed to ____.
| A．protect people from wolves and deer |
| B．protect wolves from becoming dangerous |
| C．protect wolves from dying out |
| D．keep wolves from killing large numbers of deer |
Why is it that if wolves go on killing a good many deer the wolves will die out?
| A．Because wolves will have no deer to kill. |
| B．Because people will kill them for punishment. |
| C．Because killing deer is dangerous. |
| D．Because wolves mainly live on deer. |
In order to protect more deer from being killed, one way is to ____.
| A．pass a law | B．keep deer away from wolves |
| C．kill more wolves | D．serve wolves more food |
Which of the following statements is true according to the passage?
| A．Some wolves in some areas must be killed, which others should be protected. |
| B．Wolves should be protected, for there’s a small population of it on earth. |
| C．All wolves should be protected, for they eat deer, cows and chicken. |
| D．It is necessary for scientists to protect wolves, or the cycle of life will be changed |
Cars are an important part of life in the United States. Without a car most people feel that they are poor. And even if a person is poor , he doesn’t feel really poor when he has a car.
Henry Ford was the man who first started making cars in large numbers. He probably didn’t know how much the car was going to change American culture. The car made the United States a nation on wheels. And it helped make the United States what it is today.
There are three main reasons why the car became so popular in the United States. First of all, the country is a big one and Americans like to move around it. The car makes the travel the most comfortable and cheapest. With a car people can go to any place without spending a lot of money.
The second reason cars are popular is the fact that the United States never really developed a practical and cheap public travel system. Long distance trains have never been as common in the United States as they are in other parts of the world. Now there is a good system of air-service provided by planes. But it is too expensive to be used often.
The third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don’t like waiting for a bus, or a train or even a plane. They don’t like to have to follow an exact timetable. A car gives them the freedom to plan their own time. And this is the freedom that Americans want most to have.
Less oil has caused a big problem for Americans. But the answer will not be a bigger system of public transportation. The real answer will have to be a new kind of car, one that does not use so much oil.We can learn from this passage that Americans ______.
| A．spend a lot of money traveling by car | B．travel a lot in their cars |
| C．seldom travel by plane | D．use public traffic often |
Which of the following statements is TRUE?
| A．In the United States even the poor own cars. |
| B．In the United States all the poor have no cars. |
| C．When an American has a car, he will never be poor. |
| D．An American will feel poor unless he has a car. |
In the writer’s opinion, cars are popular in the United States mainly because ___.
| A．Americans like to plan their own time |
| B．The United States does not have enough public transportation |
| C．Americans will not feel poor when they travel in their cars |
| D．Americans cannot move around without their own cars |
“A nation on wheels” in the second paragraph means that _______.
| A．everyone in the United States owns a car |
| B．the United States produces most of the cars in the world |
| C．cars play an important part in American’ life |
| D．the United States depend on car industry for its development |
We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of energy for our planet. It causes the evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms(生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere,30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.According to the passage, the root( 根本的) cause for weather changes on the Earth is .
| A．the atmosphere surrounding the Earth |
| B．water from oceans and lakes |
| C．energy from the Sun |
| D．greenhouse gases in the sky |
Only a small part of the Sun’s energy reaches the Earth’s surface because most of it is .
| A．absorbed by the clouds in the lower atmosphere |
| B．reflected by the gases in the upper atmosphere |
| C．lost in the upper and lower atmosphere |
| D．used to evaporate water from the oceans and lakes |
We learn from the passage that .
| A．all living things on the Earth depend on the Sun for their food |
| B．a forest looks dark in winter because it absorbs solar energy |
| C．only 0.023% of the energy from the Sun is made use of on the Earth |
| D．greenhouse gases allow heat energy to escape from the Earth’s surface |
