The volunteers would rather go by train than ________.
wouldrather或wouldsooner的意思都是“宁愿”，其后要求直接用动词原形。如果后边是that引导的从句，那么要求用过去时动词表示尚未发生的动作，用过去完成时动词表示对已经发生的动作的某种愿望。应用举例：Wewouldrathertalkaboutfootballortheweather.我们宁愿谈谈有关足球或者天气的话题。Iwouldratheryoucametomorrow.我宁愿你明天去。Iwouldsooneryouhadgonetheretoo.我宁愿你也去那里了。
There is a growing body of evidence to support the fact that most people suffer from a lack of daydreaming _______ an excess of it.
ratherthan而不是。otherthan不同于，除了;inplaceof代替;instead代替
The engineer ______ my father works is about 50 years old.
withwhom引导定语从句.withwhom放在从句中即为:myfatherworkswiththeengineer
The other timing system belongs in our internal clocks，which，left ________，would tie the body to a 25-hour rhythm.
译文：更不用说，另一个定时系统在我们的人体时钟内，它会使人保持在一个25小时的生理节奏上。此题考查关于leave的短语。leavebehind意为“留下，放弃”，leavealone意为“更不用说”。leaveout意为“遗漏，忽视”。
_______ for the free ticket, I would not have gone to see film so often.
从本题后半句可以看出这是一个与过去事实相反的虚拟条件句，从句中的动词要用“had+过去分词”，如果将if省略，had要位于主语之前，构成倒装句，故本题的答案是C。Haditnotbeenforthefreeticket=Ifithadnotbeenforthefreeticket。
