it is+adj./n+to do sth

it is +a\an+adj+n+to do 表示什么意思~

这个句型总结的过于繁琐,可以简化为“it is + 特定名词+ 不定式”,意思是“做某事是有帮助/好处/用处的”,其中 it 是形式主语,不定式是真实主语,名词只限于 help, use, good 等少数几个词。例如:It is a great help to use computer to look up information on line (利用电脑在线查阅资料有很大的帮助)。

It is + adj. / n. + for sb to do sth 这个句型哦·

举个例子

It【主语,形式主语】 is【系动词】 difficult 【表语】for me【状语,for 后边的me是介词的宾语】 to learn English 【真正的主语】

即:To learn English is difficult for me 【主语对某人来说,是状语不是主语】

一般情况是:不定式和动名词都可以在句中作主语,但下面一些词的后面一般用doing,如hopeless,useless,no use,no good等等。大多还是用to do作主语。 It is + no use,no good (fun,a great pleasure,a waste of time,a bore等名词)+doing sth. t is no use crying.哭没有用。 It is no good objecting.反对也没有用。 It is a great fun playing football.打篮球很有趣。 It is a waste of time trying to explain.设法解释是浪费时间。 It is + useless (nice,good,interesting,expensive等形容词)+ doing sth. It is useless speaking.光说没用。 It is nice seeing you again.真高兴又遇到了你。 It is good playing chess after supper.晚饭后弈棋挺好。 It is expensive running this car.开这种小车是浪费。

也就是It's +形容词/名词+to do sth.

闫周天麻: It is/was + adj+... 注解:句式中It为形式主语,真正的主语是adj后面所加的成分 Ⅰ to do sth. It is/was + adj(for / of sb.)to do sth,一般情况下都是用for sb.的,在adj.为描述人的品质的时候用of sb. Ⅱ doing sth. It is + no use,no good (fun,a great pleasure,a waste of time,a bore等名词)+doing sth. Ⅲ that 从句 目前常见的就这么多可加的成分来做真正的主语
