　　 答案解析

　　Ⅰ. 1. 【解析】选D。考查连词。句意: 无从知晓为何一个人会有重大发现而另一个似乎同样聪慧的人却没能做到。根据句意可知, 前后之间是对比转折的关系。while可以表示对比转折, 意思是“然而”。

　　2. 【解析】选A。考查形容词词义辨析。句意: 讲点道理吧——你不能指望我在如此短的时间内完成所有的工作。reasonable讲道理的; confident有信心的; creative有创造力的; grateful感谢的, 感激的。根据句意可知选A。

　　3. 【解析】选A。考查形容词词义辨析。句意: 兴趣对学习来说和理解能力一样重要, 甚至更重要。A项意为“极其重要的”; B项意为“可利用的”; C项意为“明确的, 具体的; 特有的, 特定的”; D项意为“相似的”。

　　4. 【解析】选D。后面的从句告诉我们, 对于操作说明我们不理解, 由此可知, 四个选项中只有complex(复杂的)符合语境。

　　5. 【解析】选A。考查动词短语辨析。let out在本句中为“泄露”的意思。take care意为“小心, 注意”; make sure意为“确信”; make out意为“辨别出, 理解”。

　　6. 【解析】选A。考查形容词辨析。less likely to do sth. 意思是: 不大可能做某事。句意: 一项近期研究表明那些关上电视, 坐下来和家人共餐的青少年比较不容易遭遇饮食不规律。B和C也可以表示“可能”, 但是这两个形容词不能用表示人的词作主语。故选A。

　　3. beneficial

　　4. reasonable

　　5. effective
