The general rule regarding agreement is very simple: a singular subject requiresd a singular verb and a plural subject requires a plural verb, e.g.
      （有關主詞與動詞之間的關係很簡單：單數的主詞需要單數的動詞；而複數的主詞需要複數的動詞，例如：）
      I am a student.
      You and I are friends.
      Several boys are playing in the park.
      But sometimes it may not be easy to tell whether a subject is singular or plural. See if you can complete the following sentences by choosing the correct word.
      （但是，有時候不容易決定主詞是單數還是複數。試選擇適當的字，填妥以下的句子。）
