单词用法:

be是一个多功能动词,在初级英语里可见四种用法:
  功能一,系动词be

  be为连系动词,中心词义是"是",句型为 "主+系+表"结构。be的形式常用am, is, are(现在式);was, were(过去式);will/can/may/must be(助动词/情态动词+原形);have/has/had been(助动词+过去分词)等。如:

  There are about 80 pyramids in Egypt.

  Will there be a football match in your school next week?

  功能四,实义be

  Kate's birthday party will be at half past six this evening.

  Jim has been in China for more than two years, but he has not yet been to Yichang.
