答案与提示

1. C 根据Of all the stars,形容词应该用最高级。 2. D 从后句说Please help yourselves.可知这饺子很好吃。 3. D 这是一个介词的固定用法。

4. A Before long表示“不久以后”,根据后面的动词将来时可知。

5. D expensive表示“价钱贵”;much表示“花钱多”,常跟在cost后;high表示“贵”,

其主语应该是“price”。

6. C “at night”是固定结构;如用“in”,则night前要用定冠词。

7. C “in”表示“在某个范围以内”,“on”表示“在某个范围以外,但两着接触”根据地

理上的实际情况,应该选此项。

8. B 在这种“It is + adj + prep + sb.”的句型中,如果介词后的名词与介词前的形容词有逻

辑上的主谓关系,(如果说这个形容词表示的是这个名词的性质或特征),此时,介词要用“of”;如果介词后的名词与介词前的形容词没有逻辑上的主谓关系,则介词用“for”。

9. A 这里的“it”用作形式宾语。而this和that不具备此用法。

10. C 这句话的主语是the car,而不是人;spend, take总是用于“人”做主语的句子中。Take

表示“花时间”,通常用于“it”做形式主语的句子中。
