Step 7　 　Millie wants to learn more about “enough”.　 Let’s look at the following:

l　　　　 S+ V+　　 adj./adv.+ (for sb) enough to do sth　

l　　　　 S+V+ so+ adj./adv + that + 从句

l　　　　 S+V+ too+ adj./adv+( for sb) to do sth

注意：①当 adj./adv.+ enough to do sth　 为肯定句时，可以改为　 so+ adj./adv + that + 从句

不可改为 too+ adj./adv+to do sth

②当 adj./adv.+ enough to do sth　 为否定句时，可以改为　 so+ adj./adv + that + 从句

也可改为 too+ adj./adv+to do sth

③当句子的主语不是to do sth的逻辑主语时，用for sb放在to do sth的前面。

④当句子的主语同时又是to do sth的逻辑宾语时，宾语省略。如果to do sth中的do是不及物动词，则要加上适当的介词。

　　 ⑤too…to…也有③和④的特点，但so…that…没有这种用法。
