Theywerewritingletterstotheirfriendslastnight.

昨晚他们在写信给他们的朋友。(没有说明信是否写完)

Theywroteletterstotheirfriendslastnight.他们昨晚写了信给他们的朋友。(表达了他们已写好的意思,整个写的过程已完成。)2)当动作延续较长时间时或表示厌烦、赞美等感情色彩时,常用过去进行时表示。如：

Hewasthinkingmoreofothersthanofhimself.他考虑别人的比考虑自己的多。(表示说话者赞扬的口气)

Theboywasalwaysmakingtroublethen.那时,他总是惹麻烦。(表示说话者厌烦的口气）3.Iwasgettingoutoftheshower.

我正洗完澡出来。“getout”出来,getoutof…

从…出来4.IwaswalkingdownCentreStreetwhenaUFOlanded.

walkdown/along

沿着……走

land“着陆、下降”,动词。takeoff“起飞”

e.g.Theplanelandedsafely.5.Thegirlwasshoppingwhenthealiengotout.

Whilethegirlwasshopping,thealiengotout.

when

与while区分：

(1)“当…的时候”,如后面连接的动词为进行时态,则用while多于用when。而when通常与瞬间性动词或延续性不强的动词连用。(2)如果while前后的动词都是进行时态,while可译为“与此同时”

Iwasreading

whilemybrotherwasdrawing.(3)当while前后的句子描述的情况相对或相反,while可译为“而”,while更强调并列的对比而非转折。e.g.Iamout-going

whilemysisterisquietandshy.

总之,when表示做某种动作的时间或瞬间,由其引
