＊此强调结构可以用来强调句子里除谓语、定语、补语外的各种成分，以引起听者或读者的注意。＊在该结构中，前后时态一致，且将Itis/was...who/that...去掉，句意通顺，句子结构完整。①主谓一致：被强调部分作主语时，其形式与谓语动词在人称和数上保持一致。＊ItisIwhoamresponsibleforthisproject.＊Itishewho/thatoftendoesgooddeeds.②人称照应：强调主语用主格，强调宾语用宾格。＊lsawhimyesterday.→ltwashimthatlsawyesterday.对“not…until…”部分进行强调Itwasnot

untilyesterdaythatIlearnedit.eg:Ididn'tlearnituntilyesterday.eg:Thefirstofthevitaminswasn'tidentifieduntil1911.Itwasnotuntil1911thatthefirstofthevitaminswasidentified.对“not…until…”进行强调，常会使用句型“Itis/was
