题目内容
19．The family didn't have enough money to buy a car．（同义句）The familycouldn't afford to buy a car．
分析 --这家人没有足够的钱买一辆汽车．
--家庭买不起一辆汽车．
解答 答案：couldn't afford．考查同义句．don't have enough money to do sth没有足够的钱做某事，可以表达为can't afford to do sth负担不起做某事．根据didn't可知是一般过去时态，因此can变为过去式could，答案是couldn't afford．
点评 同义句转换最基本的是要保持原意不变，在理解语境的基础上，抓住关键单词或词组，运用相同词意的单词或词组完成试题．
