同学您好:作主语。在不定式短语作主语的句子中,往往用 it 作形式主语,而把不定式短语放在句子的后面。如:
To die like that is a terrible thing. = It is aterrible thing to die like that.
To know oneself is difficult. = It’s difficult toknow oneself. 有自知之明不容易。
To tell a lie is not always easy. = It’s not alwayseasy to tell a lie. 撒谎并非总是容易。
注意:下列表示品质的形容词做表语时,不定式的逻辑主语由 of 引出:
careless粗心的,clever聪明的,cruel残忍的,foolish愚蠢的,good好的,kind好心的,naughty淘气的,nice好的,polite礼貌的,right正确的,rude无礼的,silly愚蠢的,stupid傻的,unwise不明智的,wise明智的,wrong错误的,等等。
比较下列例子:
oIt is difficult for me to learn English. 更强调学英语很难。
oIt is unwise of you to go to the United States at this time. 你此时去美国不明智。
