While Mary ___ a letter, the children were playing outside.

A.wroteB.writesC.is writingD.was writing

D

解析試題分析:根據(jù)語境可知此句的含義是Mary在寫信的時候,孩子們正在外面玩。此題重點(diǎn)考查的是while引導(dǎo)的狀語從句表示當(dāng)…的時候。其強(qiáng)調(diào)的是兩個動作同時進(jìn)行,并且經(jīng)常用進(jìn)行時態(tài),故選D。
考點(diǎn):過去進(jìn)行時的用法。
點(diǎn)評:when,while都有“當(dāng)……時候”的意思。when既可表示某一點(diǎn)時間,也可以表示某一段時間。在when引導(dǎo)的時間狀語從句中,其謂語動詞可以是延續(xù)性的,也可以是非延續(xù)性的,可與主句中的謂語動詞同時發(fā)生,也可在其后發(fā)生。while只能表示某一段時間,不能表示某一點(diǎn)時間。在while引導(dǎo)的時間狀語從句中,其謂語動詞只能是延續(xù)性的,而且也只能與主句中的謂語動詞同時發(fā)生或存在。如主句謂語動詞表示的是短暫動作,從句時間狀語指一段時間,when while 可通用。
while引導(dǎo)的時間狀語從句多用進(jìn)行時態(tài),而when引導(dǎo)的時間狀語從句多用一般時態(tài)。
while 和 when在過去進(jìn)行時中的用法:表示兩個持續(xù)性的動作在過去同時發(fā)生用while,when后接一個短暫性的動作。持續(xù)性的動作用過去進(jìn)行時,自然也就是要+ing了,短暫性的動作用一般過去時,所以不+ing.所以是while后的動作+ing,when后的動作一般不+ing
