＊此強調結構可以用來強調句子里除謂語、定語、補語外的各種成分，以引起聽者或讀者的注意。＊在該結構中，前后時態(tài)一致，且將Itis/was...who/that...去掉，句意通順，句子結構完整。①主謂一致：被強調部分作主語時，其形式與謂語動詞在人稱和數(shù)上保持一致。＊ItisIwhoamresponsibleforthisproject.＊Itishewho/thatoftendoesgooddeeds.②人稱照應：強調主語用主格，強調賓語用賓格。＊lsawhimyesterday.→ltwashimthatlsawyesterday.對“not…until…”部分進行強調Itwasnot
