1、讀書破萬卷下筆如有神It常見的四個(gè)句型It seemed only several minutes he made up his mind and toldus his decision.A.thatB.since C.when D.before記住四個(gè)句型，能幫助你又快又正確做這樣的題。1 . It was +時(shí)間點(diǎn)+ when sth. happened.表示：當(dāng)某件事發(fā)生時(shí)，時(shí)間(it) 是。如：It was 1997 when Hongkong returned to China.2 . It was +時(shí)間段+before sth. happened. 此句型前必有前文，表示在那件事
