it的用法归纳高中
it的用法归纳高中高中阶段，“it”这个小小的单词，可是有着大大的用处！今天咱们就来好好归纳一下“it”在高中英语中的各种用法。
先来说说“it”作人称代词的时候。
这时候，“it”可以指代除人以外的一切事物或者动物。
比如说，“Look at the dog It is so cute”这里的“it”就是指代前面提到的“dog”。
“it”还能用来指代不明性别的婴儿或者身份不明的人。
想象一下，有人敲门，你不知道是谁，这时候你可能就会问：“Who is it?”再讲讲“it”作非人称代词的情况。
“It”可以表示天气、时间、距离、温度等等。
就像“It is sunny today”说的就是今天的天气晴朗。
“It's five o'clock”这就是在说时间是五点钟。
然后呢，“it”在高中英语中还有一个很重要的用法，那就是作形式主语或者形式宾语。
这个有点复杂，咱们慢慢说。
比如“It is important to learn English well”这里真正的主语是“to learn English well”，为了让句子看起来更平衡，就用“it”来作形式主语。
还有“It is ＋ adj ＋for/of sb to do sth”这个句型，同学们可得好好记住。
到底用“for”还是“of”，得看形容词是形容事情还是人。
如果是形容事情，就用“for”；要是形容人，那就用“of”。
比如说，“It is difficult for me to solve this problem” 这里“difficult”是形容“solve this problem”这件事，所以用“for”。
再看“It is kind of you to help me” 这里“kind”是形容“you”这个人，所以用“of”。
我想起之前教过的一个学生，他总是弄不清楚“it”作形式主语和宾语的用法。
有一次做作业，他错了好多相关的题目，那叫一个郁闷。
