AD选项:evidence的定语的部分为for centrally administered complex societies in northern regions of the Middle East,其核心词是societies。在逻辑上,能作为证据的肯定不是一种社会(肯定不能是“社会的证据”,只能是“社会提升的证据”,落脚点必须在动作上),而是这个社会做的一些事情。
growing as big as 30 feet long是现在分词短语,既可以做伴随状语,也可以做定语。由于The 32 species和whale均可以发出grow这个动作,所以growing as big as 30 feet long是由歧义的;
知识点:was for身后加时间时,意思是“为期”,身后只能加非特殊的时期,例如:
This is the GMAT's attempt to cram as much redundancy into one answer choice as possible. "At first begin" is redundant. So is "that direction is the way." And why would we bother saying that the "winds in the tropics blow" in that direction? Of course the wind blows. So does this answer choice. Eliminate (A).
知识点:because of是介词,其身后的 drugs that are becoming more expensive和doctors having also written many more prescriptions for higher-cost drugs均为名词短语,这两个名词短语的核心词分别是drugs和doctors。在逻辑上,原因应该是“药物变贵”和“医生开处方”这两件事,而不是药和医生这两个名词,因此本选项是错误的。
AB选项中it就近指代一个单数名词,和前面句子里的its指代对象一致,指代单数名词the company,但根据句义,降低的是公司的利润(its profit)而不是公司(the company),所以it指代错误,不选。
知识点:
通常,在不定式短语和ing短语中添加have,表示先时性。例如:
B选项at least 和or more赘余;
粗心未一眼识别出考点是比较
错选了C忽视了fossils是复数,应保持主谓一致。that不能用于引导非限定性定语从句
economically是副词,不能修饰名词development。其次,economically的意思是“节约地”,而不是经济上的。
outlier 排除明显偏离项之后再算平均值,类似于:去掉最高分和最低分后取均值
The practicing physician must be familiar with the basic pharmacology of the various classes of hypoglycemic drugs to ensure its effective and rational use. This is becoming an increasingly complicated task given the rapid pace of progress in diabetes therapy.
知识点:Not only A but also B 二者是递进关系,不是转折关系,则前者是好事,后者必须也是好事,不能是坏事;but单独是转折关系。
考点:
题错了哦
D: Pledging..., the initiation of Project... 这里应该也是the project 发出pledging 这个动作,而不是initiation.
1.slower不正确。由于本句中的slow是在描述地震波传播的速度的,所以其应该修饰travel这个动词,应该用副词的slowly,而不是slower这个形容词。2.which是一个定语从句,应该就近修饰一个名词。
3.travel和ricochet做为合句不正确,应让travel做伴随状语,合句是并列关系,状语是从属关系.
