题目内容
It doesn’t matter _____you pay by cash or credit card in this store.
A.whether B.how C.what D.why
【答案】
A
【解析】
试题分析:这里it是形式主语,whether引导的是真正的主语从句。句意:是用现金还是刷卡付账都没有关系。故选A。
考点:考查主语从句的用法。
点评:本题难度适中。在句中作主语的名词性从句称为主语从句, 主语从句所对应的谓语动词通常用第三人称单数的形式。为了整个句子的平衡, 主语从句经常后置, 并用it充当形式主语(此时, that引导的主语从句若不放在句首, 可以省略引导词that)。it作形式主语代替主语从句主要是为了平衡句子结构, 主语从句的连接词没有变化。
即学即练:____ we’ll go camping tomorrow depends on the weather.
A. If B. Whether C. That D. Where
解析:B。下划线处的引导词之后接了一个完整的陈述句, 但整个主语从句不是客观陈述某种情况而是要表示“是否”的意思, 应选用引导词whether。注意: 表示“是否”的名词性从句的引导词if不能用于引导主语从句。

I think machine power is better than human power because we cannot survive without our daily used machines like bikes, coolers, computers, etc. | |

Johnson 6-May-2008 | Yes, it’s very clear that machine power is better than man power. But machine power has its limitations (局限). It cannot survive without electricity and manhandling. If it doesn’t have these two then it is completely useless. So man should not completely depend on machines. One more point is that because of the use of machines man has become lazy. This laziness has brought in many problems like obesity, arthritis (关节炎) and other health problems. But I am not saying that man should completely turn from machine power to man power. He should have a balance of both. Even I can’t think of life without a car, a computer and a cooler. |
Sally 9-May-2008 | Humans only created the machines. So, human power is greater than machine power. To do the things quickly we created the machines. But machines cannot think. That thinking power beats machine power. |
Tina 17-May-2008 | But without humans there is no value of any machine. If someone wants to use his machine perfectly then one must have expert labor or man power. |
Tommy 19-May-2008 | Hi to all, my opinion is that human power is more powerful than machine power, because human beings created the machines. Human brain works more compared to machines. |
