1.This boy isn't as careful as that one.This boy is less careful___ ___ than that one.
选词填空：loud true work
1.Will you please speak_louder__?
2.What a voice!It's_truly__beautiful and sweet.
3.The boss makes them_work__very long hours a day.
再问： 第一题为什么用less，more可以吗？ 选词填空第一题为什么用louder而不用loud？ 第二题为什么用truly？
再答： 第一题用more的话，就必须是more careless than 第二题一般而言都是要求你说好比之前大声点，因此要用比较级 第二题用truly这个副词修饰形容词beautiful。
再问： 第一题意思是说：这个男孩不和另外一个男孩一样小心。那就既有可能是这个男孩比另外一个男孩小心，也有可能是这个男孩不比另外一个男孩小心。那不是more和less都可以吗？我还看到还有这样的答案：This boy isn’t as careful as that one.= This boy isn’t as careful than that one.
