A.is B.were C.be D.was
,我知道suggest这是是认为的意思，后面从句不用倒装。但为什么用A，不用C呢。suggest that （should） be 结构不好用吗？

教你一个简单方法suggest that后面加的应该是一个陈述句,when做的不是suggest 的宾语而是作状语,状语可以放后面,你把when引导的状语从句放到后面就成了The article suggests that he should be especially careful to have a well-balance diet when a person ( ) under unusual stress.这下显而易见 suggest后面的从句用的就是should be结构,而后面when引导的状语从句应该和主句的时态一致,主语article后面的 suggests 用的是现在时,所以when引导的从句也应该用现在时.

when a person ( ) under unusual stress he should be especially careful to have a well-balance diet.
注意 when a person ( ) under unusual stress 是一个状态
he should be 后面有了啊
前面是状态，用IS
前面不是建议的内容啊

suggest引导了一个宾语从句，宾语从句中又包含了when引导的时间状语从句。he should be especially careful to have a well-balance diet是时间状语从句中的主句，那么when a person ( ) under unusual stress 就是时间状语从句，既然是句子，那谓语动词当然要有时态，因此用is，而不是be，此...

suggest引导了一个宾语从句，宾语从句中又包含了when引导的时间状语从句。he should be especially careful to have a well-balance diet是时间状语从句中的主句，那么when a person ( ) under unusual stress 就是时间状语从句，既然是句子，那谓语动词当然要有时态，因此用is，而不是be，此外，The article suggests 这一主句用的是一般现在时 ，因此这里用was也不对。

收起

这里的suggest是“表明”的意思，所以从句中只要使用一般的时态就可以了。
suggest还有另外一个意思是“建议”，这个时候就需要用should do 了

因为suggest只有一个句子时，用should be 结构；而它后面很明显是个主从复合句，主句用了should be 结构，所以从句与整个时态、主语一致，用is
