In English, you often see a verb followed by another verb, as in the following sentences:
在英文裏，你經常見到一個動詞後面有另一個動詞，例如以下句子：
(1) She wants to watch TV.
她想看電視。
(2) She enjoys watching TV.
她喜歡看電視。
In the first sentence, the to-infinitive (to watch) is used. In the other sentence, the -ing form (watching) is used. To decide whether to use the infinitive or the -ing form, we have to look at the first verb in the sentence. Want should be followed by the infinitive, and enjoy should be followed by the -ing form.
第一句用不定式 to-watch，另一句則用 -ing式watching。用不定式還是 -ing，決定於句子的第一個動詞。Want 後面要用不定式，而enjoy後面要用 -ing式。
The following are verbs which should be followed by the infinitive:
以下動詞後面要用不定式：
afford agree decide demand expect
fail hope learn manage plan
pretend promise refuse wish
The next group of verbs should be followed by -ing:
以下動詞後面要用-ing式：
avoid consider deny dislike
finish give up can't help enjoy
mind practice suggest look forward to
