　　5 .To keep up with the expanding frontiers of scholarship. Edward Wilson found himself ____________.（经常上网查信息）

　　答案与解析：
　　1.you would have been knocked down by a car
　　本题考察虚拟语气。句子是与过去事实相反，因此用would have 过去分词，表虚拟语气。
　　2.By no means does he regarded himself as an expert
　　本题考察倒装和词组regard sb. as sth.(把…当作…)。介词短语by no means 置于句首，构成部分倒装，因此把助动词does提前。
　　3.however, he takes it for granted
　　本题考察词组take sth. for granted (把…当作理所当然)。同时，要注意句子后半句前是一个逗号，要加上一个连词and或者加上however。
　　4.not have interfered with her marriage
　　本题考察would rather have done sth, 表示过去事件，句子中told提示是过去发生的事，因此用would have interfered with。
　　5.always searching for information on the internet
