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.
be动词后面加形容词还是副词
be动词（am,is,are）一般情况加形容词的。
I am hungry. 构成主系表结有些情况下，我们会发现一个是这样的you are totally correct. 这个并不是说be动词后面跟的是副词，这里的副词其实是在修饰后面的correct（形容词）所以应该理解为be+形容词。
但是，还有这样的句子he is highly thought of by his boss.这个句子就是be动词后面紧跟副词，这是一种习惯表达。
请问：be动词后面的形容词在句子中作什么成分
修饰的是什么成分
后面形容词肯定是表语了，这不是表语明显的定义吗，。
修饰什么成分
我没明白。
百科这样子定义表语表语是用来说明主语的身份、性质、品性、特征和状态的，表语常由名词、形容词、副词、、不定式、动词的-ing、从句来充当，它常位于系动词（be, become, appear, seem,look,sound,feel,get,smell等词）之后。
如果句子的表语也是由一个句子充当的，那么这个充当表语的句子就叫做表语从句
主语+be+形容词的句子
这不是很好写的句子嘛。
主语你应该知道。
中间加上be动词即am is are。
后面再是形容词。
如漂亮的，多的，少的，大的。
小的，饿的。
饱的，累的，轻松的。
等等~~~~~
帮忙用这个句式造句It+be+形容词+that从句
因为是祈使句，所以必须用动词原形be表强调
Be动词后面加形容词是不是相当于动词，可充当谓语
be动词后面加形容词，一起叫做系表结构，形容词作表语。
谓语是be。
