Te get contact with his family in Taiwan made him extremely happy since they separated more than 40 years ago 2. To finish that task in such a short time is really a challenge 在上述情况下,如果不定式较长,显得头重脚轻,则可由代词让作形式主语(形式主语 it 不可由 that 或 this 等其他代词代替),而将不定式放到后面。如: 1.It made him extremely happy to get contact with his family in Taiwan since they separated more than 40 years ago 2. John admitted that it is always difficult for him to be on time 不定式结构所表示的动作是谁做的,即不定式的逻辑主语,通常可以通过for sb. to do sth. 结构表达:如: 1.It is quite important for us to read good books during a general review 精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - - - - -第 1 页,共 24 页 - - - - - - - - - - 精选欢迎下载2.
