We/You/ They were working. 否定式:I/He/She/It was not working. We/You/They were not working. 疑问式和简略答语:Was I working? Yes, you were. Was he working? No, he wasn’t. 【注意】was not常简略为wasn’t; were not常简略为weren’t b) 过去进行时的用法:过去进行时表示过去某一时刻或某一段时间正在进行的动作。这一特定的过去时间,除有上,下文暗示以外,一般用时间状语来表示2.not …until直到…才。表示动作在某时之前尚未开始,直到此时动作才开始。not…until可以用after或when来代替,但主句谓语动词要用肯定形式。Until 为连词时后接时间状语从句,until作介词时,后面接表示时间的名词。Until 用于肯定句多表示动作或状态一直延续到until所表示的时间为止,意思为“直到…” from..till…中till往往表示不太具体的时间。From …to…或from…until常用来表示具体的时间。 3.find it…to do,it在此句中为形式宾语代表动词不定式,动词不定式为真正的宾语,常用于这种用法的动词有find, feel, think, make等。 4.“疑问词+不定式“结构相当于一个名词性从句,常常可用同等成分的从句代替。改写时,只需在疑问词后面加一个适当的主语(这个主语一般与主句的主语一致),并将不定式改成适当形式的谓语即可。如,Where to go is still a question.=
