几道英语单项填空
1.The new theory has proved that the assumption which ____ by some physicists two centuries ago was wrong.
A.made B.was making C.was to make D.was made
2.With more and more forests being destroyed ,large quantities of good earth ___being washed away each year.
A.are B.is C.was D.were
3.The chief reason for the population growth is not so____a rise in birth rate as a fall in death rate due to improvements in medical care.
A.much B.more C.most D.many
1、D which修饰的是前面的the assumption 是两个世纪前一些物理学家做的假设,所以肯定是过去被动式
2、 A 后面接着each year 表示的是每年都有的状态 所以不应该是过去式 而是现在式,因为是大量的 所以是are
3、A 固定词组 not so much as 意思是 与其说是……不如说是……
A
A
A(不确定)
1.D assumption是被做出来的，用被动语态；two centuries ago所以用过去式。
2.A quantities of无论修饰可数还是不可数名词、谓语动词都用复数。
3.A so much...as
第一题选D，解释：which引导的从句是修饰assumption的，which指代的是assumption，assumption应该是was made by some physicists
第二题选A，large quantities of后面谓语动词的形式应该都是复数形式
第三题选A，not so much … as …(与其说是…倒不如说是…)
D
被动语态，先行词是assumption在定语从句中做主语，谓语动词应该用单数，所以选D
A
quantities of 后面不管是可数还是不可数名词，谓语动词都是复数形式，这里很明显时态也是一般现在时，故选A
A
not so (much) ...as...是固定用法,意思是与其说是…倒不如说是...

D was made 因为时间是过去的所以用过去时的被动语态.
A are因为quantities of 作主语时谓语用复数.而不是根据后面所修饰的名词来判断谓语形式.
A much 因为它是副词可修饰谓语.其它都是比较级和最高级,不能用在此处.最后一个是形容词不能做状语所以也不用....
