advicedoing和todo的区别？
advise doing 和 advise sb. to do 最大的区别在于：
advise 后接动词作宾语时，要用动名词doing；但若其后接的动词前已经有宾语，动词用作宾语补足语时，则要用不定式 to do。
1、advise doing中间不能有宾语，advise sb. doing sth. 这种表达方式是错误的。
例：He advised going to play basketball today. 他建议今天去打篮球。
I advise waiting them to go hiking together. 我建议等他们一起去远足。
2、advise sb. to do sth. 建议某人做某事。
例：She advised us to organize a group meeting. 她建议我们组织一个团体会议。
The dentist advised me to brush my teeth twice every day. 牙医建议我每天刷两次牙。
扩展资料：advise 和 advice 的区别
advice是名词，不可数，常用a piece of advice，关于名词，是用来表示人、事物、地点或抽象概念的名称，名词同时也分为专有名词和普通名词。
例：If you give someone advice, you tell them what you think they should do in a particular situation.
He disregarded his doctor's advice.
advise是动词，可分为及物动词和不及物动词。一般出现在名词主语或主句后面，按作用和功能主要分为两大类，一类是谓语动词，另一类是非谓语动词。一般出现在名词主语或主句后面。
例：He advised us not to do the decision now.
Please advise us when the goods are dispatched.
that是什么意思？
应该是sthoccurtosb或者itoccurtosbtodo/that从句。前者有两个意思，一是“某人发生某事”，二则是“某人突然想起某事”。而后者只有一个意思，就是“某人突然想起去做某事/某人突然想起什么什么”。
amazed？
不对。
应该是sb be amazed to do sth. “对……做某事感到惊讶”.
如：
① I am amazed to see such a bad accident. 看到这么严重的事故，我感到很惊讶。
