高三英语选择题希望详细讲解，谢谢

What on earth did the manager what to know,jim?
____that we could finish the project
A When it was B What was it
C What it was D When was it

Answer 1

A
强调句型，When it was that we could finish the project.把 it was that删掉，不影响原意思
这是强调句型，强调when
(1) 陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其它部分。强调句可以强调除谓语以外的一切成分。下面我们针对I met Li Ming at the railway station yesterday.句子进行强调。
强调主语：It was I that (who) met Li Ming at the railway station yesterday.
强调宾语：It was Li Ming that I met at the railway station yesterday.
强调地点状语：It was at the railway station that I met Li Ming yesterday.
强调时间状语：It was yesterday that I met Li Ming at the railway station.
(2) 一般疑问句的强调句型：同上，只是把is/ was提到it前面。
e.g. Was it yesterday that he met my old friend?
(3) 特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分？
e.g. When was it that you were born?
我们需要注意的是：第一、构成强调句的it本身没有词义；强调句中的连接词一般只用that, who，即使在强调时间状语和地点状语时也如此，that, who不可省略。
第二、It's ....that/who....的强调句型只是为了强调某一成分，而不充当成分。所以它和It作形式主语，真正的主语从句后置的情况有所不同。
我们一起看下面两个例句:
1.It's necessary that we should learn English.(主语从句)
2.It's not until he got off the bus that he realized his money was stolen.(强调句型)
解析：因为强调句型中的It's....that/who....在句子中不充当任何成分。所以去掉后句子依然完整。
例子2去掉It's....that/who....后就成了
until he got off the bus he realized his money was stolen. 而例子1去掉后句子则不完整。
(4) not … until … 句型的强调句
1、句型为：It is/ was not until + 被强调部分 + that + 其它部分
e.g. 普通句：He didn’t go to bed until/ till his son came back.
强调句：It was not until his son came back that he went to bed.

Answer 2

A
从问题可以推测，是想知道什么时候可以完成项目。用When
然后，这里是省略了前半部分，应该是He wanted to know when it was that...
这里的关键部分如果用正常顺序表示，是
It was when that we could ...的强调句式
因此，放在从句中，就是when it was that...

Answer 3

D When was it

When was it 本身就可以成为一个句子，后面加that引导从句 具体进一步解释
