suggest that+子句，应该用原形动词，由于动词前面省略 should 的原故。上面这句话为什么用过去式动词 went? 是否书本的编辑错误?
当suggest 不表示“建议”，而是“说明，显示，暗示”之意时，其宾语从句则不需要虚拟语气。
His gesture suggested that he didn’t agree with me. 他的姿势暗示出他不认可你的建议。
大家把suggest 的两个使用方法放在一个句子中，请比较并记住：
Her pale face suggested that she was seriously ill, and her parents suggested that she should go to see the doctor.
她苍白的脸色显示她病得非常厉害，因此她爸爸妈妈建议她去看大夫。（第一个suggested 是“显示”，第二个suggested 是“建议”）
insist 也有类似使用方法，当它表示“坚持一个事实”时，其宾语从句也不需要should；当“强调一个倡导”时，宾语从句才用should。比如：
The thief insisted that he had not stolen anything from the supermarket, but the manager insisted that he should be sent to the police station.
小偷坚持说他没从超市偷任何东西，但超市经理却坚决倡导把他送到警察局。
