　 （ （1）

　）

　参考答案及解析 一、 1. C

　由 than 可知用比较级，故排除 A 项；比较级前面可用 much 修饰，不能用 very 或 more 修饰，又排除 B、D 两项。故选 C 项。

　2. A

　not as … as 是 as...as 的否定结构，意为“不如……”，两个 as之间用形容词或副词的原级，故选 A 项。

　3. D

　由 than 可知应用比较级。四个选项中，只有 D 项是比较级。

　4. D

　a little 可以修饰比较级，表示程度。very，too 和 quite 都不能修饰比较级。

　5. A

　由 than 可知应用比较级。more 不能修饰比较级，先排除 B 项；C 项 much 后应接比较级，D 项 less 后应接形容词或副词的原级，又可排除 C、D 两项。

　“less+形容词或副词的原级+than”表示“不如„„”，故选 A 项。

　6. C

　考查形容词的比较级。句意：将会有更少的工作给人们，因为有一些机器人将做和人们一样的工作。A. many 许多，B. more 更多；C. fewer 更少；D. fewest 最少。根据 some robots will do the same jobs as people 可知机器人做了人们的工作，因此人们做的工作就更少了。故选 C。

　7. A

　考查形容词的比较级。句意“对不起，这件外套不够大。我想要一个更大点的”。根据句意可知是选大点的，而 C 和 D 是小的意思，所以排除，想要的是一件比原来那个大一点的，这里含有比较意味，

　故选 A。
