用法辨析

    aux. (助動詞)

  • be用作助動詞時可與動詞的現在分詞連用,搆成進行時態,也可與及物動詞的過去分詞連用,搆成被動結搆。
  • be可以和動詞不定式連用，有以下幾點意義：①表示計劃或安排要發生的事或打算要做的事，不定式可用被動式，在was或were後用不定式的完成式可表示“本來打算…”；②表示“必須”“得”等，意思接近must, have to；③表示“應該”“宜於”等，意思接近should，有時用來征求對方的意見，不定式可用被動式；④表示“可以”“能”等，意思接近can, may，多用於被動結搆；⑤表示“想要”等，意思接近want to, intend to；⑥表示注定要發生的情況，常用於過去式；⑦表示虛擬語氣，用於與事實相反的條件句中。
  • be置於句首引起倒裝句，可表示虛擬語氣，這帶點文學色彩，不太常用。

    • linkv.

  • be作系動詞可用於There is/are句型，意思是“有；存在”。
  • be還可與名詞、代詞、形容詞、副詞、介詞短語、動詞的現在分詞及過去分詞、動詞不定式或名詞性從句連用，以提供名稱或信息。
  • be還可用於It is/was句型，用於描述情況或表達想法，也可用於表達時間等。
  • be還可與mine〔yours, etc.〕或for me〔you, etc.〕等連用，表示某物的所屬。
  • be還可與表示數量等的名詞連用，表示花費、值、等於、等同等義。
