参考答案及解析:

巩固与拓展

1、costlier -> costly
此句costly是形容词，意思是“昂贵的”。它的比较级形式是more costly。costlier是错误的形式，须改成costly。

2. bright -> brighter

3. likely前加more
此句的意思是：很少有电子应用软件能够像机器人那样引起人们对未来就业机会的担忧。
此处是 more likely … than 比较结构

4. more -> /

有些含有比较意义的形容词，不能与more, er, than连用的，如：preferable to,superior to=better than, inferior to劣于，prior to=before, second to仅次于, inferior to等。

5. than -> as

综合练习

1. give -> gives
这句话的主语是Every human being，是单数，故谓语动词也要用单数形式。

2. dispose后加of
Dispose of是固定搭配，意为“处理”。

3. an -> the

4. gives -> given
此处的given off是作heat的定语。

5. object -> objects

6. convention -> onventional
Convention是名词，要用其形容词形式修饰fuel，意为“传统燃料”。

7. the -> /
此处不是比较级的最高形式，此处的most意为“大多数”，不需要加任何冠词。

8. heat -> heated

9. are -> is
这句话的主语是the technique，of saving heat and redistributing it是作它的定语，所以位于要用单数形式。

10. less -> more
