参考答案：
1. D
老板强调指出，要做一名合格的服务员必须使自己的服务让顾客满意。本题考察介词的使用。do sth. to the satisfaction of sb. 的意思是“把某事做得使某人满意”，其他三个选项均不合题意。
2. C
在经过多年的努力工作之后，我才意识到金钱本身并不能带来幸福和成功。本题考察考生对虚拟语气和倒装句的正确使用。only after 表示“在……之后”，要求后面跟虚拟语气，同时，如果把only after置于句首则要求用倒装语序，综合考虑只有C答案正确。
3.C
worthwhile意思是“值得花费时间、金钱或精力的。”worthy可以表示“值得尊重或考虑的”，用这一意思时通常做定语。worthiness是worthy的名词形式。worth用作表语，意思是“有某种价值的;值得(做某事)”。本句需要填入一个作定语的形容词，所以，C是正确答案。
4.C
你本该把牛奶放到冰里。我想现在这牛奶不能喝了。从句意分析，牛奶已经变质，不能喝了，属过去发生的动作对现在造成影响，再加上by now是现在完成时的典型时间状语，故选C)
5. D
工厂引入自动控制之后，所有由手工进行的工作都将让位于装配线。本题是短语辨析题，主要考察考生对give way to 与take the place of 等短语/词汇的区别。give way to (让位于)既包含着take the place of / replace的意思，又不仅仅是take the place of / replace 的意思，它强调了被比较对象的关系，如 A gives way to B 表示“B 取代了A，A 因退步/落后等原因让位于B”。所以本题答案是D。
6. A
游客们正要欣赏壮观的海啸，突然一阵浓雾出现了，整个景色变得一片模糊。词语辨析题，要求考生能够辨析blur等词语，并学会正确使用。blur—把视线、界限等弄得模糊不清;belittle—轻视，使……显得渺小;ban—禁止，取缔;collapse—倒塌，失败，崩溃。
