to這個英文.....

Question

to是介系詞或是不定詞到底要如何分辨?? 一定都是要用背的嗎??

Answer 1

主要分法是:
to後面如果加原V. 則此to是不定詞
to後面如果加名詞或Ving.則此to是介系詞
可以直接背 也可常用 用久了就知道 哪個是不定詞 哪個是介系詞

如以下動詞後面固定+ to+原V.
agree+ to + V. She agreed to go mountain climbing with us yesterday.
appear+ to + V. It appeared to be a false alarm.
decide+ to + V. We decided to take the exam.
expect+ to + V. I don't expect to get a beautiful girlfriend.
fail+ to + V. He failed to pass the exam=He failed the exam.
hope+ to + V.We hope you can come next Saturday.

pretend+ to + V. She pretended to be a nice girl.

seem+ to + V.You seem to have a mood.
want+ to + V. I don't want to go home with you.
can't wait+ to + V. I can't wait to join the wild party.

以下動詞是先加受詞(o.)再用to+原V.

remind, teach, tell, want, warn,
