Question

A．a(chǎn)nd then they told him	B．when it was learned by him
C．a(chǎn)nd then he learned	D．when he learned

Answer 1

D

試題分析：考查when的用法：when當(dāng)…時(shí)候，也可以是“這時(shí)”相當(dāng)于at that time，可以構(gòu)成had done…when…這個(gè)固定結(jié)構(gòu)，意思是：剛剛做完…這時(shí)…,用when更加簡潔。句意：Roger剛剛走進(jìn)辦公室，這時(shí)他知道他的計(jì)劃最后通過了。選D。
點(diǎn)評：when之前的分句為主要?jiǎng)幼鞯陌l(fā)生提供時(shí)間背景。這一背景和主要?jiǎng)幼髦�間有三種情況。1.某一連續(xù)性動(dòng)作正在發(fā)生，突然發(fā)生另一事件。be doing…when…，2.某一短暫性動(dòng)作就要發(fā)生時(shí)，突然發(fā)生另一事件，阻止了前一動(dòng)作的發(fā)生。be about to do/ be on the point of doing…when…，3.某一動(dòng)作已經(jīng)完成，突然發(fā)生另一動(dòng)作：have/had done …….when
