老师您好： You should do some exercise to keep healthy.中的should do可否换成need to? 为什么？
should do可否换成need to
should do可否换成need to
解题思路： 首先弄清楚should do sth.与need to do sth的意思及所给出的题目想要表达的意思然后在分析解答
解题过程：
should do sth.应该做某事；need to do sth 需要做某事,需要去做某事,要做某事。句子You should do some exercise to keep healthy.（你应该做一些运动来保持健康。）而You need to do some exercise to keep healthy.(你需要做一些运动来保持健康。)就表达的意思来说都是说“You"要保持健康要通过做一些运动来做到，从这个意义来讲二者互换对句子意思的表达没有根本性的影响，其中细微的差别是用should有“建议”的意思，而用need“提醒”的意思强些。但如果换一个环境或句子就不一定能够表达相同的意思了，这要具体情况具体分析。
