我也来问3个问题，LZM语法改错里面的

E11-59

During the Renaissance，scholars were uncertain as to be location of Troy, and by the eighteenth century many historians doubted that troy had never existed.

为啥是A而不是

C) were in doubt as to the existence of Troy

c平衡对仗得多好啊

11-46

LZM解释道，All his children are not at school. (他的有些小孩在上学，有些没有）

然后下面有一题

Although all the proceedings of the Communist party conference held in Moscow were not carried live, Soviet audiences have seen a great deal of coverage.

key: E) not all the proceedings of the communistist party conference held in Moscow were carried live

解释说a中not本来是修饰all的，却去修饰了谓语。那么这样说的话，上面那个例子岂不是Not all his children are at school.

E9-29 The number of XXXXX more than doubled from 1900 to 1973.

这是一句话么？难道doubled是谓语？

第一题，我和你的想法一样。

第二题，如果和例句对比，我怎么也分辨不出来为什么例句中not可以随意走动不改变意思，而题目中的not只能在all前面。

第三题，我想问有用more than修饰谓语动词的其他情况吗？还是说这是个固定搭配？
