参考答案
1．B

2．D
【详解】句意：我喜欢春秋两季的户外活动。
A. activity活动，B. actin行动；C. activityes活动，名词复数不对；D. activities活动，名词复数。activity 是可数名词，utdr activities表示户外活动。根据题意，故选D。
3．B
【解析】试题分析：句意：巩俐被当做中国最著名的女演员之一。此题根据句意，结合常识，应该使用女演员这个名词，而ne f结构后面应该使用复数名词。故选B。
考点：考查名词单复数。
4．B
【详解】句意：这是一个非常令人兴奋的动作电影。
因为主语是this，所以actin mvie应用单数形式，排除A、C两项；very的发音以辅音音素开头，所以前面的不定冠词用a，故答案选B。
5．B
【详解】句意：事实上，尽管珍妮花的钱最少，但她给妈妈的礼物是最好的。
考查副词。Actual实际的；Actually事实上；Unlucky不幸的；Unluckily不幸地。根据后文“best ne”可知，此处不表示不幸，只能表示实际上，并且要用副词来修饰整个句子，副词除了可以修饰动词之外，还可以修饰形容词和整个句子，这也是副词的一大特点，同学们不要忽略了这几大特点，故选B。
【点睛】形容词变副词，通常是直接在形容词后加后缀ly，但有时要去e加ly，有时直接将e变为y，有时要变y为i再加ly，还有的时候加ally，显得比较复杂，下面的口诀可帮你正确地把形容词变成副词。
①形容词变副词有规律，后缀ly加上去。
②e结尾，要注意，前为元音要去e。
③要是结尾le，前为元音也去e，前为辅音e变y。
④y结尾不读[ai]，先要把y变成i。
⑤ic结尾加ally，public要除开。
6．A

8．B
【详解】句意：——你流鼻涕了，杰克。你感冒了吗？——没错！重感冒！
考查时态。根据“D yu have a cld?”可知，说话时，他看到杰克正在流鼻涕，才问杰克是不是感冒了，用现在进行时。故选B。
9．C
【解析】
试题分析：句意：我不能准确地说那个房子什么时候建的，但是它一定是很久以前。房子被建立，用被动语态，lng ag为过去时间状语，故选C。
考点:考查被动语态。
10．B
【详解】句意：——电影很精彩。——在某些方面，它是精彩的。演员们还行，但是故事不是很有趣。

11．B
【详解】句意：——你讨厌李，是吗？——并非如此，我只是觉得他有点懒，仅此而已。
考查情景交际。Of curse.当然。Nt exactly.并非如此，不完全是。Certainly.当然。Nt fr sure.不确定。根据“I just think he is a bit lazy”可知，我并非讨厌他，我只是觉得他有点懒。故选B。
12．B

14．C15．D16．B17．D18．A
