We'd better take action/do something to guard against the spread of some diseases．

Answer 1

分析 We'd better take action/do something to guard against the spread of some diseases

解答 答案：We'd better take action/do something to guard against the spread of some diseases
根据汉语中的"最好做某事"确定用句式had better do，其中had可以放在主语后面缩写成"'d"．注意几个重点短语的翻译：①"采取措施"take action/do something ②"防范"guard against ③"疾病的传播"the spread of some diseases．另外注意"防范疾病的传播"是"采取措施"的目的，故用动词guard的不定式形式．故答案为：We'd better take action/do something to guard against the spread of some diseases

点评 had better 是一个固定搭配，相当于一个情态动词had better do 最好做某事，后面跟动词原形．如：
You had better go to school now．你现在最好去上学．记住：不要用have代替had，因为它是一种固定搭配．
