英语2道问题,请详细给出语法解释.!!!!!

4 When ____ why he was so late ,he just looked at us and said nothing.
a.being asked b.asking c.asked d.to be asked 为什么选c
5 ___ from the tower, the city looks just magnificent.
a. To see b. Seeing c.To be seen d. Seen 为什么选D

Answer 1

其实两道题是一个类型。
所选词的从句在句中都做状语，并且是被动语语态。
以4为例，
按这两个标准来选，a,c,d,都可以，
但是，a.中表进行或将来，c.也有表将来的意味。c. 是过去分词，一方面表被动，一方面表过去，正合题意。
5.同上

Answer 2

1题是 因为这个句子是过去式，A为过去进行式，B为错误的，语法不通。 D为被动语态，语句不通
2题选D，以前高中老师讲过的，印象很深刻，应该为一个省略句：have seen

Answer 3

是这样的，英语句子中，从句中的主语如果和be动词在一起，则主语和be动词可以一起省略。注意，两者都要省略，不能只省略主语也不能只省略be。像：
After （he was) kept waiting an hour, John got so angry that he went away.
When (we are) reading ,we are supposed to be quiet.
省略可以让句子显得简洁，避免重复啰嗦。

Answer 4

4因为你可以把它看成是when he was asked why he ....
he was 省略
5.理解成原句:the city was seen from the tower....,
省略前面那部分
如果选C,就缺少了主语
