提示板:若變成被動語態(tài),在上述結(jié)構(gòu)中,不定式符號to要加上。如:
They are made to work 16 hours a day by the boss.
She was heard to sing in the next room.
4.作定語:放在被修飾的名詞、代詞后面
例句:I have a lot of work to do.
The doctor said he could do nothing to help the boy.
點擊規(guī)律:動詞不定式若在句中作定語,常放在被修飾的名詞、代詞之后。
提示板:如果動詞不定式和前面所修飾的詞構(gòu)成動賓關(guān)系,若動詞是不及物動詞,切記不要忘掉介詞。如:
I have a small bedroom to live in.
Have you got some pens to write with?
