学的东西都还老师了，惭愧，

主句中有suggest, suggestion, advise, advice, order, command等时,宾语从句要用should do形式,should可以省略.

suggest后的动词都要用原形，不管是 suggest to 还是suggest后面的从句

一想要：desire
二命令：order, command
三建议：advise, suggest, propose
四要求：demand, require, request, insist
推荐：recommend
以上动词所引起的名词性从句中使用should+do的虚拟语气，should也可以省略。
