The schooling of the child at home becomes a family activity．Parents get involved in every step of the learning procedure．Field trips and experiments become family activities．Thus, the child receives more quality time with his parents．The entire family shares games, housework and projects．Family closeness becomes the focus here．

Individual attention is another obvious benefit of home-schooling．For example, if your child needs more time to learn math, then he can reduce the time for his English lessons．There are no fixed hours of learning per subject．This means that a child has the advantage of focusing additional time on the subject that seems hard．

Home-schooling gives the parent more control over the influences that affect your child．The growth and development of your child is established by you child is established by you and you determine what your child needs to do of learn．

Competition is limited when it comes to home-schooling, The child does not need to prove his ability with regard to other children or compete for attention．Since parents have a deep understanding of their child, they can plan the learning program to keep the child’s interest．It is also possible to mix difficult tasks with fun activities．A tough hour of Algebra(代数)can be followed by trip to the nearest museum or a vacation that you can make part of your child’s education．Some children learn through reading, while others need to write, and still others need to see objects in action．

More and more parents are disappointed with the public school system．They believe that their children are being pushed too hard or too little．Some parents themselves have unhappy memories of their own public school experience and that motivates them to choose home-schooling when it comes to their own children．

1.According to the first paragraph, the benefit of home-schooling is that   

       A．children needn’t spend so much time learning English

       B．children don’t have to worry about their poor subjects

       C．parents are important to the growth of their children

D．children have more time to stay with their parents

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

       A．Parents can make their children more competitive．

       B．Children don’t have to face competition with other children．

       C．Parents can help their children work out the problems．

       D．Parents can encourage their children to join in more activities．

3.Why are many parents likely to choose home-schooling for their children?

       A．Because they can save a large amount of money．

       B．Because their children are often punished by teachers．

       C．Because they have unhappy memories of public school system．

       D．Because they can teach their children by themselves．

4.According to the passage, the author’s attitude to home-schooling is    

       A．favorable           B．disappointed       C．satisfied             D．surprised

The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to represent all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world’s food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the Norwegian island of Spitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on Earth.

An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his words,“the worst came to the worst.” Norway is expected to start work next year. The project is expected to cost three million dollars. Workers will drill deep in the side of a sandstone mountain. Temperatures in the area never rise above zero degrees Celsius. The seeds will be protected behind concrete walls a meter thick and high—security doors.

The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will come from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below zero Celsius. The cold weather would protect the seeds even if the air could not be replaced.

Mr. Fowler says the proposed structure will be the world’s most secure gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first proposed the idea in the 1980s. But security concerns delayed the plan. At that time, the Soviet Union was permitted use of Spitsbergen. New Scientist says the plan won United Nations approval in October at a meeting in Rome of the Food and Agriculture Organization.

55.The project is meant to_______.

A.increase the world’s food production in the future

B.carry out some scientific experiments on plant genes

C.protect crop seeds from dying out in case of possible disasters

D.build an exhibition centre of the world’s plant seeds

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

A.The government of Norway will perform the project alone.

B.Seeds to be collected there were produced ten thousand years ago.

C.Spitsbergen is chosen because it is away from the threat of unclear war forever.

D.Temperature is a major consideration when choosing the storage place.

57.We can infer from the text that_______.

A.People will get newly?developed seeds from the center every year

B.The storage center will greatly promote the development of world agriculture

C.Norway meant to have built the storage centre more than 20 years ago

D.There haven’t been any seed storage centers in the world before

58.What is probably the best title of the passage?

A.Noah’s Ark(诺亚方舟) of Plant Seeds in Plan.      B.The Best Place to Store Seeds.

C.Concerns of World Food Supply.                 D.A New Way to Feed the World.

Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unequally heats the surface of the Earth. As hot air rises, cooler air moves in to fill the gap. As long as the sun shines, the wind will blow. And as long as the wind blows, people will manage it to power their lives.
Ancient sailors used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to make electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small part of the world's energy.
Most wind energy comes from turbines that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These devices look like giant airplane propellers(螺桨)on a stick. The wind spins the blades, which turn a shaft connected to a generator.
The biggest wind turbines generate enough electricity to supply about 600 U.S. homes. Wind farms have tens and sometimes hundreds of these turbines lined up together in particularly windy spots, like along a ridge. Smaller turbines set up in a backyard can produce enough electricity for a single home or small business.
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments decrease tax to encourage wind-energy development.
Some people think wind turbines are ugly and complain about the noise the machines make. The slowly rotating blades(螺旋风片) can also kill birds and bats, but not nearly as many as cars, power lines, and high-rise buildings do. The wind is also changeable: If it's not blowing, there's no electricity generated.
Nevertheless, the wind energy industry is increasing sharply. Globally, generation more than quadrupled(四倍) between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes. Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China.
Industry experts predict that if this pace of growth continues, by 2050 the answer to one third of the world's electricity needs will be found blowing in the wind
