Unless_____by credit card,please pay in cash.
A.pay B.is paid C.paying D.paid
答：最佳选择为C
分析：本句主句为后面的祈使句.前句为加了连词的分词短语作状语（也可以理解为省略了主+Be的状语从句）.因为逻辑主语是you,与pay是主动关系,所以用现在分词=Unless you are paying by credit 或Unless you pay by cash,...
Unless paying by credit card,please pay in cash.
如果不用信用卡付账,就请付现金.
To achieve his heart's desire,he is racing the clock all the time.He is not the man_____he was two years ago.
A.which B.that C.who D.whom
答：B.关系代词that可指人或物,在从句中可作表语,而关系代词whom在从句中作宾语.
此句中用关系代词that指代the man,在从句中作he was 的表语.
You can't help but hear commercials,every few minutes the program is interruped to give you one advertising_______
A so on adn so forth B.more or less C.something or other D.sooner or later
答：C
something or other“什么的（表示模糊概念）”,常用于口语,如：Something or other,prevented him from coming.不知什么事使他来不了了.so on and so forth“等等”；more or less“或多或少”；sooner or later“迟早”.
其实此题没有改编好：
英语四级语法200条之动名词练习题- 北斗论坛日语|自考|在职研究生|考研 ...
11) You can't help ____ commercials; every few minutes the program is interrupted to give you one advertisement or another.原来的是：one dvertisement or another
我们知道,something的形容词定语是要后置的：something strange,而原题中的one advertising something or other 感觉上很怪的.
网上还有根据它改编的题：

13 Dec 2006 ...You can't help ______ commercials,every few minutes the program is interrupted to give you one advertising something or other
原题为在职硕士联考英语模拟试题的29题.答案确实为C.
再问： 最后一道题为什么不是sooner or later 呢？？？我觉得从意思上也讲的通啊
再答： 因为前面已经有状语Every few minutes 了。。翻译一下就知道了 You can't help but hear commercials,every few minutes the program is interruped to give you one advertising ______. 你不得不听商业广告。每过几分中节目就中断给你来上一条广告【什么的】。或迟或早，没位置放了。如没有Every few minutes,则可以：the program is interruped to give you one advertising sooner or later. 【 或迟或早】节目就会中断给你来上一条广告。
再问： 错了。。是为什么不选more or less 或多或少 每过几分钟就或多或少来段广告，不是也讲的通吗？？
再答： 前面是one advertising,好象没有讲完。(这是本题没改好的地方），即使是one advertisement,因为已经指出是一条广告，就不必说或多或少了。看看more or less的用法吧。
