题目

这是个句型吗,形容词加of结构 the way 有时候要加that不加that怎么区分,
It was generous of her to contribute such a large sum.
they quickly learn the way that their society expects males and female to behave and think .
there are also difference in the way parents talk to their children
这两句分别是什么从句

答案

第一句的句型为：It be +形容词+for/of+sb+to do something
it 在句中充当的是形式主语,真正的主语是后面的to do something
整个句子还原则为：To contribute such a large sum was generous of her .
第二个句子,从"that"开始一直到句末为定语从句,修饰the way
第三个句子,从"parents"开始到句末同样为定语从句,修饰way
一般情况下,that可加可不加,但当that在句中充当成分时,则一定不能省
掉而且只能用that：
当先行词是anything,everything,nothing (something 除外),few,all,none,little,some等代词时,或者是由every,any,all,some,no,little,few,much,each等修饰时
(1) Have you taken down everything (that) Mr.Li has said?
(2) There seems to be nothing (that) seems impossible for him in the world.
(3) All that can be done has been done.
(4) There is little (that) I can do for you.
