用法辨析
- be用作助動詞時可與動詞的現(xiàn)在分詞連用,構成進行時態(tài),也可與及物動詞的過去分詞連用,構成被動結構。
- 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(fā)生的事或打算要做的事，不定式可用被動式，在was或were后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”“宜于”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，多用于被動結構；⑤表示“想要”等，意思接近want to, intend to；⑥表示注定要發(fā)生的情況，常用于過去式；⑦表示虛擬語氣，用于與事實相反的條件句中。
- be置于句首引起倒裝句，可表示虛擬語氣，這帶點文學色彩，不太常用。
- be作系動詞可用于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(xiàn)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還可用于It is/was句型，用于描述情況或表達想法，也可用于表達時間等。
- 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(shù)量等的名詞連用，表示花費、值、等于、等同等義。
- be還可與everything〔nothing, etc.〕 (to sb)連用，表示對某人的重要性。
