動詞不定式的用法
不定式結構作主語
1. 不定式前置
1） Derive [A] mineral resources from [B] sedimentary rock [C] is a [D] major modern industrial activity.
2） in the matriculation for postgraduate in a short time is realy a hard nut.
[A] To make high scores[B] To make low goal[C] To the high scores[D] Make the low goals
2. 上述形式一般情況不多見，作為考試的規范英語，如果不定式較長，顯得頭重腳輕，則可由代詞“it”作形式主語（形式主語“it”不能由“that”或“this”等其他代詞代替），而將不定式放到后面
It is really a hard nut to get high scores in the matriculation for postgraduate in a short time.
3） John admitted that it's always difficult .
[A] for him being on time[B] being on time for him
[C] for him to be on time[D] on time for him
4） It is difficult for me [A] to be concentrating [B] while someone [C] is using [D] a vacuum cleaner.
3. 不定式后置的情況不僅限于動詞是系動詞，也適用于其他動詞
It took us a great deal of efforts to finish that task.
It made him extremely happy to get contact with his family in Taiwan since they separated more than 40 years ago.
4. 不定式結構所表示的動作是誰做的，即不定式的邏輯主語，通常可以在特定的上下文中能看出，也可以通過帶“for +名詞短語”辨出
It is quite important for us to read good books during the period of general review（總復習）。
It is not difficult for those who study maths well to pass the exam.
5. 在某些形容詞（如careless，clever，considerate， foolish， good， impolite， kind， naughty， nice， silly， stupid等）作表語時，不定式后可以加of來引導出其邏輯主語
It is very kind of you to help me./It is stupid of him to do such a silly thing.
間或也可用for + there to be 表示（而且there后面的不定式只能是to be）。
It's a great pity for there to be much trouble in the company.
