1. had better (not)do sth. 最好(别)做某事
had better为情态动词，其后需用动词原形。had better常用缩写，变成'd better，其否定形式是在其后直接加not.例如：We had better go now. = We’d better go now. 我们最好现在走吧。You'd better take a rest. 你最好休息一下。
You'd better not go out because it is windy. 今天刮风，你最好别出去了。
2. have sth. done 使(某事)完成，使发生 (动作由别人完成)
sth.为宾语，done为过去分词作补语。例如：
We had the machine repaired. 我们请人把机器修好了。
注意区分：We have repaired the machine. 我们(自己)已经修好了机器。
3. help sb. (to)do sth./with sth. 帮助某人(做)某事
其中的to可以省略。例如：I often help my mother with housework.我常常帮助妈妈做家务。
Would you please help me (to)look up these words? 请你帮助我查查这些词好吗?
4. How do you like……? 你认为……怎么样?
与what do you think of …?同义。例如：How do you like the weather in Beijing? 你认为北京的天气怎么样? 你觉得这部新电影如何?
—What do you think of your boss? —He is strict with us.
5. I don't think/believe that… 我认我/相信……不……
其中的not是对宾语从句进行否定而不是对主句(否定前移)。that可省略。例如：
I don't think it will rain. 我认为天不会下雨。
I don't believe the girl will come. 我相信那女孩不会来了。
我认为他并不聪明。
