简单动词、情态动词和助动词的顺序排列为：
情态动词+时态助动词/语态助动词+简单动词、情态动词+简单动词、助动词+简单动词。但是，需要注意以下几点：
1）情态动词后面一定是加上简单动词或者助动词的原形，如：① He can use the computer now. ② He should have taken the document.
2）否定形式是直接在情态动词后加not，若没有情态动词则在助动词后面接not，如：① I cannot answer your question at present. ② Tom’s novel has not been punished yet.
3）疑问形式是直接把情态动词提到句首，若没有情态动词则将助动词置于句首，如：① Can you speak Chinese ? ② Does she know some English?
