It is good for him to take exercises. 14.find----found---found (1) find it + adj. + to do sth. it 为形式宾语,to do 为真正的宾语,可以用于这种结构的动词还有 think, feel, make 等 e.g. I found it easy to learn Chinese. I find it cheap and fun to travel that way. I felt it very difficult to go there on foot. (2) find + that 从句 e.g. I find (that) he is a good man. 15. It’s faster to take a bus than to walk. 此句型为 it + is + 形容词比较级 + to do than to do,注意比较的前后两部分必须性质相 同。

语法: 动词不定式作主语 动词不定式的基本形式为“to + 动词原形” ,其否定形式是“not to +动词原形” 。它能起 名词的作用,在句子中充当主语、表语、宾语和宾语补足语。动词不定式在作主语时, 用法主要有以下两种: 一、动词不定式作主语时常用 it 作形式主语,而往往将动词不定式放在谓语或表语之后。 It's not easy to learn a foreign language well. (=To learn a foreign language well is not easy.) 学好一门外语不容易。 在此句型中,如果要说明动词不定式的动作是谁做的,可在不定式前加一个 for 引起的 短语,作不定式的逻辑主语。如: It's difficult for us to finish the work. 对我们来说,完成这项工作很困难。 It's hard for me to answer your question. 要我回答你的问题很难。 但是, 如果表语是 kind, nice, right, wrong, clever, polite 等描述行为者的性格、 品质的形容 词,则应在不定式前加一个 of 引起的短语。如: 这个例子属于上面的换一个 of 引起的。 It's very kind of you to help me.你能帮我,真好。 注意: 1. of sb.和 for sb.这两种结构还有一个区别,在 of sb.结构中,可用 sb.直接作句子的主语 来改写成“It's+形容词+of sb.+动词不定式”结构。试比较: It's foolish of him to go alone. (=He was foolish to go alone.) 他单独出去太傻了。 It's kind of you to give me the book. (=You are kind to give me the book.) 你给我这本书,真 是太好了。 for sb.结构则不能这样转换。e.g.,不可以说:We are difficult to finish the work. 2. 动词不定式作主语,同时有另一个不定式作表语时,不能转换成“It's...to do sth.”的 句型。如: [正] To see is to believe. 百闻不如一见。 [误] It's to believe to see. 二、 “疑问代(副)词+动词不定式”也可以在句中作主语。如: How to begin the work is a big problem.
