高中英语问题，帮帮忙 ，谢谢了

1 （B） The cloths on sale in this supermarket are much cheaper than______in Mr Green's shop.
A that B those C ones D these
B

2( C )Marry ______of visiting her grangmother,but the bad weather made her change her mind
A has thought B thought C had thought D had been thought 为什么不能选 A 呢?
在日常用语中一定不算你错，但是既然是选择题，就是选‘最’准确的。那么从时间上来判断，是Mary思考在先，坏天气再后，所以用过去完成时最准确。

3( D )It is said in the book that Thomas Edison _____the world's leading inventor for sixty years.
A would be B has been C had been D was B或C为什么不行?
（同上）。这里是陈述一个事实，所以用一般时态。

4( B )Generally speaking, _______according to the directions,the drug has no side effect.
A when taking B when taken C when to take D when to be taken D为什么不行?
习惯用法

5( C )Some animals are dying out,________the fact that they have been hunted and that the forests have been seriously destroyed.
A that has something to do with B and has a lot to do with
C which has much to do with D what is somethingto do with
A（如果前面的逗号改为句号，就可以选A了）
B （后半句的主语和前半句的主语不匹配）
C
D （有C作对比，一定是C了）

6 The written examination ,where all students are tested on the same questions was probably not known until the 19th century .
中on the same questions 什么意思?这句话什么意思?
笔试，也就是所有的学生都考同样的题目（的这种形式），可能知道19世纪方为人知。

1、`B
2、后半句的时态是过去式是指过去决定的.过去完成时常用来表示发生在过去的两个事件、动作哪个发生在前。而现在完成时是指过去发生的动作对现在造成的影响或结果。所以不能选 A。
3、本句意思为据说……，叙述事件用一般过去式
4、B为主动语态D为被动
5、C
6、在同样的问题上。

1,those代替前面的clothes
2，A是现在完成时，强调对现在的影响，C是过去玩成时，表示动作发生在过去的过去，看后面的一句话是过去时
3，for sixty years 是时间段 吥是时间点 be动词寇以用于时间段
算了 觉得行的话 找我吧
