5.The villagers didn't realize how serious the pollution was until all the fish died in the river.→Not until all the fish died in the accidentdidthe villagersrealizehow serious the pollution was.
→It was not until all the fish died in the accidentthatthe villagersrealizedhow
serious the pollution was.
分析 直到河里的鱼都死光了村民们才意识到污染多么严重.
解答 答案是did,realize;that,realized;比较原句和改写句发现,第一句改写句是将原句中的not until题到句首,Not until放在句首,(主句)句中用部分倒装,故第一句第一格用助动词did;第二空用动词原形realize;第二句改写句是改写成not until 的强调句型"It is/was not until…that…,强调句型中无倒装语序;故第二句改写句的第一空是强调句型中的that;not until同时放在被强调部分,第二空中用过去式realized的肯定式.
点评 本题考查句型转换,在比较原句和改写句的基础上分析同义结构或句型,要积累常见同义词、同义短语和同义结构.
