题目内容
19．他服药以防止感冒恶化．He took medicinesto prevent the cold from getting worse．．
分析 to prevent the cold from getting worse．
解答 答案：to prevent the cold from getting worse．
首先通过中英文句子的比对，可知英文句子中缺少"以防止感冒恶化"的表达．短语"防止…做某事…"的英文表达是：prevent…from doing …；句子中的"恶化"是get worse，本题中，"防止感冒恶化"是前面"服药"的目的，所以使用动词不定式，故答案为：to prevent the cold from getting worse．
点评 做这类题型，首先根据所给汉语明确句子所要考查的单词或短语的拼写，再结合相关语法知识对单词或短语做出形式上的变化．
