　　4 .Janet told me that she would rather her mother ___________.(不干涉她的婚姻)
　　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
