　　答案解析：

1. A) 介詞at經常放在表示“技能和知識”的詞前, 表示 在這方面的.能力和技能。

2. C) 此空所在句雖然有“”，但是經過分析可知句中存在一 個半助動詞“be likely to”，故此空選C。

3. B) 在做此題前首先要分析清楚此句的句子結構。此空所在句的主句是“ It is well k nown”，它帶有三個that引導的賓語從句，其中此空所在分句是第三句。根據上下文可推測 此句句意為：眾所周知，實際上所有偉大的數學家一直都是男性。因此，根據句意和主句時 態可知正確答案為選項B。

4. B) 根據上下文意義可知答案為B。

5. A) 首先“解決爭端”需要使用動詞settle和debate搭配，另外try to d o意為“努力做某事”，而trydoing意為“嘗試做某事”，意義不符。故A為正確答案。

6. D) 根據語法線索可知此空應使用過去完成時。

7. A) 根據句義可知A distinct“明顯的”為正確答案。其它三詞意義分別 為：instinct“本質的”;remote“遙遠的”; vague“模糊的”。

8. D) 四個選項中首先可以排除選項B However，因為它不是連詞。而Since 和As是引導原因 狀語的從屬連詞;while為引導讓步狀語從句的從屬連詞。根據句義和句子結構，此空正確 答案為D。

9. D) 根據上下文可推測句義為：儘管男性和女性的語言能力沒有什麼區別 ，但是…。據此答案為D。

10. C) 根據上文的統計資料可以得出結論：男性天生就比女性具有 更高階的數學推理能 力。故正確答案為選項C inherently “本性地，固有地”。其它三項意義都不準確：super ficially意為“表面地”; universally意為“普遍地”; initially意為“最初，開始”。

11. C) 非限定性定語從句需要由which引導。

12. B) Not a few和some意義接近，由於是and連線的並列結構，故答案為B。

13. D) 此空前雖然出現動詞suggest，但是從句中的動詞不用虛擬語氣形式 be，因為suggest在這裡意為“表明”，而非“建議”。

14. D) 此處為both … and …結構。

15. C) “得出結論”由動詞reach和conclusion搭配。
