3道英语题，能详细解答的请进。

Question

分给说的最清楚最详细的朋友，谢谢！

It's wasn't such a good dinner ____ she had promised us.
A. that B. as C. which
应该选哪个？是强调句吗？是宾语从句吗？如何辨别？

What worried him most was his not being allowed to visit his sick child.
这个句子为什么不能写成What worried him most was he was not being allowed to visit his sick child.
his的用法这里弄不懂。

In my opinion, life in the twenty-first century is much easier than it was used to be.
In my opinion, life in the twenty-first century is much easier than it used to be.
2个句子哪个对还是都对？为什么？
第一题我打错了，应该只有wasn't，但我相信应该能看的出来。

Answer 1

1.B对 as……在这里是一个从句 强调句和宾语从句的区别你可以百度一下 such……as……是一个固定词组 所以不选C It was/is…… that……是强调句的固定句型 考试时可能迷惑
要分析清句子结构还有句子意思
It was a good dinner that she had promised us.这个强调句还可以。
但是你翻译一下题目（注意NOT和SUCH） ，显然不是强调句。
2.What worried him most was he was not being allowed to visit his sick child.
was not being 病句
可以写成
What worried him most was that he was not allowed to visit his sick child.
that在这里可以省略不可以我也不清楚 反正加上没错
sb's doing sth.是一种结构 就把它当成一个名词性词组吧 “他的……”转换成句子sb就是主语

3.第二个对 was used to 习惯于
used to 过去

Answer 2

It wasn't such a good dinner _as_ she had promised us.
晚餐并不如她所说那么好。
What worried him most was his not being allowed to visit his sick child.
What worried him most was that he was not allowed to visit his sick child.也是可以的。
最令他担心的是他不可以探访他病了的孩子。后面是worry的对象，必须是宾语，所以用他“不可以探访”的事实。

In my opinion, life in the twenty-first century is much easier than it used to be.
used to be是曾经的意思。如果was used to be.就是被用于的意思了。本回答被提问者采纳

Answer 3

B. as
意思是，不如她所承诺的
不是强调句

这个句子为什么不能写成What worried him most was he was not being allowed to visit his sick child.
能啊 - 也没错
his 这里的用法就是 - 他的 的意思
后面的not being allowed to visit his sick child 就成了名词了
像 - What worried him most was his (sick child)
只是给例子，意思并不一样

语法上， 第一个也没错
就是句子重复了，it was = it used to be
第二个比较正确

Answer 4

that 这句是宾语从句 要一个that连接
What worried him most was he was not being allowed to visit his sick child. 里面的主语重复了,在这里用一个his来代替he was
第二个是对的,因used to be本来就是过去..无需加was

Answer 5

b. such as 这是固定词组搭配,意思:如....一样

his not being =his situation of not being ....

In my opinion, life in the twenty-first century is much easier than it used to be. 是对. 因为BE USED TO 意思是习惯.....
