There is no need与it is no need有什么区别哪些词前用there is,哪些词前用it is

1） It was last night ___ I see the comet

Athe time Bwhen Cthat Dwhich

答案C强调句的结构是：It +be +强调部分 + that (who) + 主谓句强调句的连词只有两个,that和who当强调的部分是人,且为句子的主语时,才用 "who",其余用that

原句：My father did the experiment in the lab yesterday evening

强调主语：It was my father who did the experiment in the lab yesterday evening

强调宾语：It was the experiment that my father did in the lab yesterday evening

强调时间：It was yesterday evening that my father did the experiment in the lab(注意不用when)

强调地点：It was in the lab that my father did the experiment yesterday evening

2）It is ten years ___ Miss Green returned to Canada

Athat Bwhen Csince Das

答案C考点是连词用法本题易误选为Athat其实本句不是强调句若是,去掉It be… that还应是一个完整的句子而本句去掉 'It is…that',只剩下ten years Miss Green returned to Canada不成句因此本句不是强调句

It is /was +时间+ since… 其中is has been was had been

"It's + adj +of sb to do sth"这个句型，在使用时，主要是注意句型中的形容词。

表示聪明或愚蠢的形容词,有clever, wise, foolish, stupid, silly, unwise, dumb(愚笨的), absurd (荒谬的)等,。如:

It’s silly of him to do such a thing 他竟干出这样的事,真是愚蠢!

表示正确或错误的形容词,有 right ,wrong, correct, incorrect 等。如:

It was right of her not to come here 她没有来这儿,太对了!

表示好坏等品性的形容词,此类词较多,有 good, nice, kind, sweet, friendly, lovely, wonderful, jolly(快活的), bad, unkind, naughty, wicked(坏的,邪恶的)等。 如：

It’s friendly of you to come and see me 你能来看我,真够朋友!

表示褒义或贬义色彩的形容词,有brave, polite, careless, selfish等。如:

It was brave of you to manage to do it 你居然能做成这件事,真勇敢!

注意：句型中的sb和adj存在“主语和表语”的关系，提出来可以造个句: sb +is(are) + adj + to do sth 例如：

It's very nice of you to help me 你来帮助我，你真是太好了。

（我们可以说：You are nice to help me)

"There is no need" 和 "It is no need" 都表示“不需要”，但前者是比较常用和自然的表达方式，通常更容易被人理解和接受。后者则不太符合英语表达习惯。

一般来说，"There is" 表示某个事物的存在，因此通常与 "no/any/some/more/less" 等词搭配使用，例如：

There is no problem

There are some issues in the codebase

There will be more features added in the next release

而 "It is" 则常常指代先前提到的事物、情况或状态，并进一步说明其特点或属性，大多数情况下它通常带有一个形容词或名词短语，例如：

It is difficult to solve this problem

It was a beautiful day in the park

It will be interesting to hear his speech

尽管对于不同的场合可能会有不同的表达方式，但总体而言，需要根据具体上下文和语境来决定是否使用 "there" 或 "it" 开头的表达方式。
