If the earth stopped moving, everything _____.

A. would disappear B. disappeared

C. will disappear D. disappears

 

A

【解析】

試題分析：if的虛擬語(yǔ)氣非常重要，簡(jiǎn)要概括如下：1、表示與現(xiàn) 在事實(shí)相反的情況，從句：If主語(yǔ)+過(guò)去時(shí)(Be動(dòng)詞用were)；主句：主語(yǔ)+should/would/could/might+do：　2、表示與過(guò)去事實(shí)相反的情況，從句：If主語(yǔ)+had+done；主句：主語(yǔ)+should/would/could/might+have done　3、表示對(duì)將來(lái)情況的主觀推測(cè)，從句：①if+主語(yǔ)+were to do②if+主語(yǔ)+should+do ③if+主語(yǔ)+did（動(dòng)詞過(guò)去式）/were ；主句：主語(yǔ)+should/would/could/might+do；根據(jù)第一句中的stopped，可知本句應(yīng)該是與現(xiàn)在事實(shí)相反的虛擬語(yǔ)氣，使用主句中使用would+動(dòng)詞原形。句義：如果地球停止轉(zhuǎn)動(dòng)，一切都會(huì)消失。故A正確。

考點(diǎn)：考察虛擬語(yǔ)氣

Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live－ in the middle of a modern city, or a faraway village the chances that you will be disturbed by jet aeroplanes, transistor radios, oil-powered engines, etc, are almost everywhere. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they are working.

Scientific tests have shown that total silence can be very frightening experience for human beings. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓). The noise level in some disco is far above the usual safety level for heavy industrial areas.

One recent report about noise and concentration(專(zhuān)心) suggested that although a lot of people say that any noise disturbs their concentration , what really affects their ability to concentrate is a change in the level of noise. It goes on to say that a background noise, which doesn’t change too much (music, for example ) may even help people to concentrate.

A. Noisy Life B. Background Noise
