Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources（来源）, as well as one of the oldest. Evidence shows that windmills（风车）began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

For many centuries, people used windmills to grind（磨碎）wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s, when electricity was available to people in almost all areas of the United States, windmills were rarely used.

During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

All parents in England want to send their children to high school.But sending a child to a school is the first step that many parents find difficult to take.In theory，at least，the problem is that there are many choices to make.Let us try to list some of the alternatives (两选一) between which parents are forced to decide.To begin with，they may ask themselves whether they would like their child to go to a single­sex school or a co­educational school.They may also consider whether the child should go to a school that is connected to a particular church or religious group，or whether the school should not have such connections.Another decision is whether the school should be one of the vast majority financed by the state or one of the very small but influential (有影响的) minority of private schools，though this choice is，of course，only available to the small number of those who can pay.Also connected with the question of money is whether the child should go to a boarding school or live at home.Then there is the question of what the child should do at school.Should it be a school whose curriculum (课程) lays emphasis，for example，on necessary skills，such as reading，writing and mathematics，or one which pays more attention to developing the child’s personality，morality，emotion and sociality.Finally，with dissatisfaction with conventional education as great as it is in some circles in England and certainly in the US，the question might even arise in the parents’minds as to whether the child should be forced (强迫) to go to school at all.Although in practice，some parents may not think twice about any of these choices and send their child to the only school available in the immediate neighborhood，any parents who are interested enough can insist that as many choices as possible be made open to them，and the system is theoretically (就理论上) supposed to provide them.

A．there is a limited number of choices

A．don’t find conventional education satisfactory (满意的)

B．don’t know how to choose among different schools

C．intend to educate their children themselves

D．find conventional education too expensive to pay for

63．What is implied (暗指的) at the very end of the passage?

A．Most parents are unconcerned about the choices available to them.

B．Interested parents can request more school choices be open to them.

C．The educational system may not provide as many choices as expected.

D．Most parents usually send their children to the schools nearby.
