Question

五道英语题 请务必给我正确答案 这个对我很重要很重要 谢谢大家帮忙了

他花了五年时间才完成这部小说。
It __________________________________ the novel.

我发现读那本书很有用。
I find ___________________________________ that book.

要放弃那个计划很困难。
It is difficult ____________________________.

嘲笑你的同学是不对的。
______________________________________ your classmate.

他们认为有必要告诉她事情的真相。
They found ____________________________________tell her the truth.

这些可能跟动词不定式 to do 有关系 但也许没关系 不要受局限
并且适当加一些讲解解释 谢谢大家了！

Answer 1

1 It took me five years to finish the novel.（固定句型：IT TAKES SB SOME TIME TO DO STH。 某人花费多长时间做某事）
2 I find it useful to read that book.
3 It is difficult to give up that plan.
4 It is not right to laugh at your classmate.
5 They found it necessary to tell her the truth.
（2、5 也是固定用法‘FIND IT +形容词+TO DO STH ’； 3、4是固定句型‘IT IS +形容词+TO DO STH ，动词不定式作主语，IT是形式宾语）

Answer 2

他花了五年时间才完成这部小说。
It _took him 5 years to finish_ the novel.

我发现读那本书很有用。
I find _it useful to read_ that book.

要放弃那个计划很困难。
It is difficult _to give up the plan_.

嘲笑你的同学是不对的。
_It is not night of you to laugh at_ your classmate.
（或_It is wrong of you to laugh at_ your classmate.）

他们认为有必要告诉她事情的真相。
They found _it necessery to_tell her the truth.

抱歉，刚才第四句题目看错了

补充一下，像第二、五句类此的用法，还有这些词也可以：make think feel
具体句型是：feel/think/find/make+it+adj+to do sth
语法是这样的：如果不定式（宾语）后面有宾语补足语，则用it作形式宾语，真正的宾语（不定式）后置，放在宾语补足语后面

Answer 3

1.It took him 5 years to finish the novel.
2.I find it is useful to read that book.
3.It is difficult to give up that plan.
4.It is not right to laugh at your classmates.
5.They found it necessary to tell her the truth.

花费时间用take it takes sb. sometime to do sth.固定句型
it 形式主语 真正的主语在后面 to do 形式
第2个和第5个是形式宾语
