it is加形容词加that 是什么意思
1.It is + 被强调 + that ... 就调句 该是强调句型。
将被强调的部分放在前面，其它部分置于that之后。
被强调部分可以是主语，宾语，表语或状语。
强调的主语如果是人，that可以由who换用。
如果把这种句型结构划掉后，应该是一个完整无缺的句子。
这也是判断强调句型与其它从句的方法。
It was about 600 years ago that the first clock with a face and an hour hand was made. It was they that (who ) cleaned the classroom yesterday. It was in the street that I met her father. 补充：2. It is not until + 被强调部分 + that ...该句型也是强调句型。
主要用于强凋时间状语，译成汉语”直到．．．才．．．”，可以说是 not ... until ... 的强调形式。
It was not until she took off her dark glasses that I realized she was a famous film star.= Not until she took off her dark glasses did I realize she was a famous film star.= I didn’t realize she was a famous film star until she took off her dark glasses. 3. It is clear ( obvious, true, possible, certain....) that ..... 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为”清楚（显然，真的，肯定．．．）” 是主语从句最常见的一种结构。
It is very clear that he’s round and tall like a tree. = That he’s round and tall like a tree is very clear. 4. It is important ( necessary, right, strange, natural...) that ... 该句型和上一个同属一个句型。
由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。
建议记住该句型中的形容词。
It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned....) that ... 该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。
该结构常译为”据说（据报道，据悉．．．）”。
It is said that he has come to Beijing. It is reported that another earth satellite has been put into orbit. 6. It is suggested ( ordered ... ) that ... 该句型和上一个同属一个句型。
主句中的过去分词是表示请求，建议，命令等词时，that 后的从句要用虚拟语气（should + 动词原形），should 可以省。
常译为”据建议；有命令．．．） It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours. 7. It is a pity ( a shame ... ) that ...该句型中，that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为”竟然”。
没有这种意义时，则不用虚拟语气。
It is a pity that such a thing ( should ) happen in your class. 这种事竟然发生在你们班上，真是遗憾
It is a pity that he is ill. 他生病了，真遗憾
8. It is time ( about time ,high time ) that ... 该句型中that 后的从句应该用虚拟语气，值得注意的是① 常用过去时态表示虚拟．② 有时也用should + 动词原形，should 不能省。
常译为”是（正是）．．．的时侯．．．”。
It is time that children should go to bed. = It is time that children went to bed. 9. It is the first ( second ... ) time that ...该句型要和上一个句型区别开来。
该句型中的 that 从句不用虚拟语气，而用完成时态。
至于用什么完成时态，由主句的谓语动词的时态决定。
如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。
该结构中 that 可以省去；it有时用 this 替换．常译为”是第一（二）．．．次．．．”。
It is the first time I have been here. = This is the first time I have been here.
It is加形容词加 for或of 怎么区分
it‘s adj. for sb. to do sth.对于某人来说做某事…例如：It's difficult for me to learn maths.学数学对于我来说是困 it‘s adj. of sb. to do sth对于某人来说做某事体现了其……格。
例如：It's kind of you to help me .你帮助了我，你很善良
it is后面加什么词比如是名词还是形容词
itis原它是...”而is是系动词，直接充当动词，所以后面可名词，可以词，也可以跟形容词，还可以跟宾语从句。
①加名词例如：“Itisanapple.”意为“它是一个苹果”②加形容词例如：“Itiscute.”意为“它很可爱.”③加代词例如：“Itismine.”意为“它是我的.”这里的mine是所有格，指“我的东西”以上
What后加形容词 比如what great weather it is.那么how 的相关用法是
how强调的是形容词或副词，而what 强调的是名词，记住下列句型：How +形容词\\\/副词+主语+谓语+……
How +形容词 +a \\\/ an +单数名词+主语+谓语+……
What a \\\/ an +形容词+单数可数名词+主语+谓语+……
what +形容词+复数可数名词\\\/不可数名词+主语+谓语……
it is 后加形容词还是副词?
加形容词，后面的形容词作表语，修饰BE动词，这句话里的BE动词就是is.副词则是修饰实意动词，比如：It moves normally.这时的normally作为副词，修饰move这个实义动词。

请用 It is +形容词+ for sb to do sth 造20个句子，形容词最好不相同
It is+形容词+of sb to do sth 中的形容词是形容人的品质的，例如：It's kind of you to help me.It's nice of you to help me.It is wise of them to turn down the suggestion.他们很明智，拒绝了这个建议。
（强调的是them是明智的。
）而It is+形容词+for sb to do sth中的形容词则是形容事物的性质的，例如，（1）It is wise for them to turn down the suggestion.他们拒绝这个建议是很明智的。
（强调的是to turn down the suggestion这件事是明智的。
）（2）It is impossible for me to finish the job.（3）It is possible for you to get there in only 15 minutes.（4）It's hard for him to give up smoking.（5）It is important for him to finish the task in time.（6）It is good for you to study hard in English.（7）It is difficult for me to learn English.（8）It is easy for me to climb that tree.（9）It is very dangerous for the children to cross the street.（10）It is necessary for you to learn from others.（11）It is useful for you to learn how to repair TV sets.（12）It is exciting for the children to play bumgee jumping.（13）It is useless for you to quarrel with him.（14）It is wonderful for us to join in the contest.（15）It is wrong for you to do this.（16）It is unwise for you to accept his gift.（17）It is right for you not to accept his gift.（18）It is horrible for me to go through the forest in the night.（19）It is nice for me to work with her.（20）It is interesting for me to go to movies with her.（21）It is a pity for me not to marry her.最后一例中的a pity不是形容词，但意义上也相当于一个形容词。
顺便说一下，楼上的第1、4、6、7句也对。
但第2、5句中的for应改为of，第8句中的excited应改为exciting（因为excited只能指人的心理活动，在这样的句子结构中它只能与of搭配）。
请楼上的别见怪，我是就事论事哟。
It is +形容词 for sb\\\/sth to do sth。
For后面不是人也可以吗。
例如.
这位网友， 这个中 for 后面也有是 sth的，不过有是确定的，那就是：这个 sb \\\/ sth 在道理上一定面那个 to do 这个动作的发出者。
在上面这个句子中，由于 your eyes 不能进行 “play computer games“这个动作，所以这个搭配不够恰当。
这个句子想要说的意思可以这样表达出来：Playing computer games is bad for your eyes.希望以上解释能够对你解开疑问有所帮助。
