Infinitive and -ing (Part 1 of 3)
      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，例如以下的句子：
      (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.
      第一句句子用不定式 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後面用不定式，而enjoy後面要用-ing式。
      The following are verbs which should be followed by the infinitive:
