→if your son feels so well that he can watch tv by then，he’ll fine after the game.
(2)在具有否定意義的句中，三者可以相互轉換，但應注意too…to在和enough to do sth. 與so…that…轉換時，應用句中形容詞的反義詞或將that從句改為否定句。
如：
he is too young to join the army.
→he is so young that he can’t join the army.
或：he isn’t old enough to join the army.
(3)如果so…that…結構中主句和從句的主語不是一致的，應在enough to do sth和too…to結構中的不定式前加上“for sb.（sth.）”的短語。
如：
english is so useful that all of us should learn it well.
→english is useful enough for us to learn well.
the maths problem is so difficult that i can’t work it out.
→the maths problem is too difficult for me to work out.
或: the maths problem isn’t easy enough for me to work out.
3. like后既可接動詞-ing形式，也可接動詞不定式。含意卻有所不同。
如：
he likes swimming in summer.（表示習慣愛好）
it’s very hot. he would like to（have a）swim.
(表示具體的一次行為)：hate等也有類似的用法。
