Question

14．The children couldn't help laughing whilethey were watching （watch） the humorous cartoons．

Answer 1

分析 孩子們在看幽默漫畫時(shí)禁不住笑了．

解答 答案：they were watching  考查單詞填空．根據(jù)題干中的could可知時(shí)態(tài)是一般過去時(shí)，while引導(dǎo)的時(shí)間狀語從句通常同時(shí)發(fā)生，故后面也要用過去進(jìn)行時(shí)，構(gòu)成 是主語+was/were+doing，主語用they，助動(dòng)詞用were，watch的現(xiàn)在分詞是watching，故答案是they were watching

點(diǎn)評(píng) 解答此題的關(guān)鍵是根據(jù)語境推測要填內(nèi)容表達(dá)的含義，然后能理解各選項(xiàng)內(nèi)容，有時(shí)可能沒有必要細(xì)細(xì)區(qū)分每個(gè)單詞的含義，僅根據(jù)句子語氣就可以判斷出正確答案．
