A.Hearing notB.Having not heard
C.Not hearingD.Not having heard

分析 好久都没有收到他朋友的来信,他决定再次跟朋友写信.

解答 答案:D
解析:后面主句使用的是一般过去时,而"没有收到朋友的来信"发生在"再次写信"之前,故前面(原因状语)从句使用完成时,因此A、C选项直接排除.非谓语动词的否定形式是直接在非谓语动词之前加not,故B选项排除.综上,本题答案为D选项.

点评 本题考查非谓语动词,做此类题目时一定要仔细分析句子结构,确定非谓语动词的形式及时态;再结合所给选项选出正确答案.

2.Think about the different ways that people use wind.You can use it to fly a kite or to sail a boat.Wind is one of our cleanest and richest power sources,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 19 40s 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.
