所以选择E，这里的as是一种特殊用法，指代前面一件事（television can be superficial）更多讨论，参看雷哥网试题链接：https:///og18-15533.html#quantId2. Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years agoand extending for more than 30 acres in the soil of a Michigan forest.A. extendingB. extendsC. extendedD.it extendedE.is extending正确答案：A该题平均耗时：1m59s ，平均正确率：32%来源：精选题库参考解析: 考察with的修饰问题。

With短语放在句子中只能就近修饰前面的名词，而不能修饰其他词性，因为test-driven不是名词，所以只有D正确更多讨论，参看雷哥网试题链接：https:///question/14458-%E9%80%BB%E8%BE%91CR.htmlenrollment of colleges in India.A. equivalent to the enrollment ofB. the equivalent of those enrolled inC. equal to those who are enrolled inD. as many as the enrollment ofE. as many as are enrolled in正确答案：E该题平均耗时：2m4s ，平均正确率：28.1%来源：Manhattan参考解析: 首先AD用enrollment与前句的人数做对比，造成比较对象不平行，错。

其次BC中those只能指代人或物，并不能指代人数（数量），所以不对。

最后E用了一个很聪明的方法，它直接省略了人数，只用了have done来表示我是有主语的，只是主语和前句一样，所以我给省略了，而前句主语是数量，自然后句也是数量，这样比较对象就平行了。

4. In 1994 the white house named Dr RuthR. Faden chairperson of the federal advisory committee of expertsthey assigned to do a report on the history and ethics of the government’s radiation experiments on humans in the 1950’s and 1960’s.A. they assigned to doB. to be assigned doingC. that was being assigned doingD. assigned for doingE. it assigned to do正确答案：E该题平均耗时：2m4s ，平均正确率：28.1%来源：GWD参考解析：首先看assign的用法，assign sth.；assign sb. sth.；assign sth. to sb.assign sb. to sth.；assign sb. to do sth.没有assign for doing，所以D错误的原因在这里○ A的问题是they的指代○ B是违反固定搭配○ C是being结构冗余○ E正确是因为Chairperson of...of...+修饰成分，修饰的是chairpersonit指代的是the white house, 这是个定语从句，因为所修饰的内容在从句中作宾语，所以that省略没有问题【其实就是考察嵌入式关系从句：在E中，其实"of experts"和"it assigned"中间省略额一个"that"，完整形式是 ...the federal advisory committeeof experts that it assigned to do...此处“that it assigned”就是嵌入的句子，它既是先行项的后置修饰语（即定语），同时又是另外一个分句结构的宾语5. Like the Dreyfus affair at the turn of the century and the Sacco-Vanzetti trial inwas the first time a congressional hearing was shown on television.(A) the more so because it was(B) more for its being(C) more for the reason that it was(D) the more so for the reason because it was(E) the reason of it being more so is that it was正确答案：A该题平均耗时：1m28s ，平均正确率：28.7%来源：精选题库参考解析：首先，more so是一个习语，其中so指代前文中提到的整个action。

其次对比AC，C中用到了for the reason that的表达，明显没有because简截了当，有redundant的嫌疑6. Building large new hospitals in the bistate area would constitute a wasteful use of resources, on the basis of avoidance of duplicated facilities alone.A. on the basis of avoidance of duplicated facilities aloneB. on the grounds of avoiding duplicated facilities aloneC. solely in that duplicated facilities should be avoidedD. while the duplication of facilities should be avoidedE. if only because the duplication of facilities should be avoided正确答案：E该题平均耗时：2m34s ，平均正确率：28.7%来源：GWD参考解析：A of duplicated facilities ，duplicated时态不对，would表明在过去将会发生，duplicated则是复制出的B of avoiding duplicated awkwardC 错误同AD while不能引导虚拟语气E 句子的意思到这个时候才能水落石出。

【介词摆放位置的修饰对象不一样】3、关于是否加an，本句语义，并不是说在美国，而是在进入浪漫主义时期的美国，表示的是一个时期，或者时代，所以加上an的话更加清晰，所以选A。
