参考答案1.【翻译】等今晚你的飞机着陆时，我在机场就已经等三个小时了。［考点］动词时态【精析】D“by the time”意为“到……时间为止”，引导时间状语从句。根据句中的时间状语tonight并结合句意可知，“在机场等待三小时”是发生在将来的持续性动作，所以要用将来完成进行时，表示将来某时、某事之前已经发生的动作，一直延续到将来某一时间。故选D。
2. 【翻译】一项有关学生观点的调查表明：学生们也承认，连续几小时坐在电脑前对健康有害。［考点］主谓一致【精析】B主句的中心词是A survey， 所以谓语动词应用单数形式shows。admit后面是省略了that的宾语从句，从句的主语是several hours of sitting in front of the computer，其中several hours是中心词，是表示时间的复数名词，表示整体意义，作主语时，谓语动词应用单数形式，即is。故选B。
3. 【翻译】一些本地公司正在努力与外国公司竞争，以获得一定的市场份额。［考点］词义辨析【精析】Cconnect：连接；combine：组合；compete：竞争，常与介词with搭配使用，意为“与……竞争”；compare：比较。根据句意可知，选C。
4. 【翻译】既然你得到这么好的机会，就要好好利用。［考点］状语从句【精析】Anow that引导原因状语从句，意为“既然”；after引导时间状语从句，意为“在……之后”；although引导让步状语从句，意为“尽管，虽然”；as soon as引导时间状语从句，意为“一……就”。根据句意可知，选A。
5. 【翻译】在我向你解释清楚整件事情后，你会发现这些困难之处的。［考点］动词时态【精析】C根据句意和从句中的after可知，主句动作发生在从句之后。从句用了一般现在时表将来，所以主句应用一般将来时。故选C。
