我来答这句“Electricity is the phenomenon (associated with) positively and negatively (particles charged) of mater (at rest) and in motion, either (individually) or in great numbers.”
positively and negatively 在这里应该修饰形容词，改成positively and negatively charged particles...就对了
另一句“the lenses in an optical microscope bend the light passing through a specimen to form an image of that specimen that is much larger( than the one )actually viewed”
这里指的是the image of the specimen thus formed is much larger than the image of specimen actually viewed, 为了避免重复，所以改成了the one，更详细地写完整就是..than the one which is actually viewed, 此处省略了which is,因为定语从句中的which＋be可以省略。但是如果选than it, 句子就会变成这样：...than it which is actually viewed,显然读起来怪怪的。
还有“Basalt,(which) composes (most )of the ocean (floor ) is a dark-grey rock (rich) in iron and magnesium than surface rocks.The answer is D yet my choice is B. I am inclined to change “most’ to “mostly”.”
因为句子中有than surface rocks可以判断是个比较句，所以rich应该改成richer就对了。不过说来惭愧，要让我选第一眼看上去没准也会觉得most有些怪，只不过你告诉我答案了，我才觉得rich有错误，唉，还是得认真看题啊。
另外你说的第一句，我的感觉是这样，不知对不对，大多数情况下，richest（最高级）前面要加the，有时甚至后面还跟个它修饰的名词，一般在句中做的是主语宾语或插入育（也可能是从句中的），总之是名词性的，但是这句里richest在be后做的是表语，如果加the反倒画蛇添足了。

觉得TOEFL选的相对MISTAKE,考过GMAT的人不要用GMAT的语法来对付.
多看选项,全面了再下结论.排除法也好哦.
