2、outh Palace last ni ght.強調地點狀語：It was in the Youth Palacethat I saw a film last night. 強調時間狀語：It was lastnight that I saw a film in theYouth Palace.一般講，原句的謂語動詞如果是現(xiàn)在或將來各種時態(tài)，用It is - that (who);如果原句 謂語動詞是 過去各種時態(tài)，則用It wasthat(who)。讓息點在強調主語時，that后的謂語動詞要與被強調者保持人稱和數(shù)的It is I who am a teacher.即使被強調的主語是復數(shù)，主句

3、中的謂語動詞也用單數(shù)It is they who often help me with my less ons.在強調時間、地點、原因、或方式狀語時，不要用 when,where,why或 how ,而用thatIt was because her mother was ill that she did n't gowith lie在強調 notuntil結構中由until5m（或從句）表示的時間狀語時，that 從要用固定的強調句型It is(was) notun til .that.句中的謂語動詞用肯定式My father did n't e home until 12 o
