D选项有些想当然了,比例高不一定代表平均数高,有可能区域贫富差距很大,所以平均水平还是M更高。
F act1: p(a)<p(hf)
Fact2: p(a+hf)/p(a)=0.95
A 没有提到两个谁先发生,无法证明是先决条件
E p(a+hf)/p(hf)<0.95 因为分母变大,故正确
正确思维
这是数学题吧。。。
not so much….as…..与其说....不如说
这是在考verbal还是在考数学啊
E defend是支持的意思
错选E,没有理清楚题目的逻辑方向,
H发现在XX里的温度并没有预计的那么高,
Geologists' pre-1965 assumptions concerning heat generated in the fault were based on calculations about common varieties of rocks, such as limestone and granite
但是这个忽略了clay
有clay的岩石会产生更小的摩擦力,进而摩擦力产生热量的假设是不对的。
Under normal conditions, rocks composed of clay produce far less friction than do other rock types.
错选C,其实并没有experiement,全文都是在解释一开始提出的一个现象。
OG还提到一个点可以把C干的片甲不留:如果几年前的极端天气导致的是大豆产量下降,那么大豆价格也会升高的,所以。。完全没法解释现在的情况好嘛
看到很多朋友也和我曾经一样错选C,想明白了给大家解释一下。1.为什么Nevertheless,...不是结论:因为结论需要前提去back up,这句话前面没有任何前提,只是说大豆的“产量”在极端天气不增反降,和大豆的”价格“并没关系。2.为什么不是相关因果型:题目有提到一对相关性:极端天气和大豆”产量“不受影响;结论的相关性是极端天气和大豆”价格“上升。大豆产量和价格是不能直接替换的,至少不能不加解释就替换掉。(而且这里大豆产量上升了,按照经济学常识大豆价格应该下降,和题目给的情形矛盾了,更不能把大豆产量和价格直接替换了)总结:注意题目中具体讨论的重心是什么,不要看到soybean什么就当作一回事。
built in/prior to 不是谓语,The greatest road system 后面一串是同位语
这道题答案是不是有问题,条件2得(c+3)/(d+3)=4/5啊,怎么求不出来
Statement 2: c+3/d+3 = 4/5
4c + 12 = 5d + 15
4c - 5d = 3
还是不理解正确选项。even though引导的从句作为插入语,但是感觉这个从句并没有依附的主句呢
我觉得是:相关因果(末尾同时说了因果)
因:提高最低工资
果:我付不起钱,我要裁员
要求削弱
A:留住员工的钱 比 提高工资需要的钱 有得一拼(他们工资低,一直在闹,公司需要花钱留住他们,这笔钱不便宜,跟加工资出的钱没什么区别了)。所以,你要是选择加工资,那么他们就不会闹了,成本不会增加。也就是说,你不会付不起钱的。因 推不出 果,削弱
The difficulty (of finding and retaining employees) adds as much to employment costs as (would raising wages)
你理解错相关因果的意思了。相关因果要求前提和结论都有一对AB成因果关系。比如前提是:下雨的时候,总能见到蚊子。结论是:下雨会导致蚊子变多。所以本质上相关因果的推理过程是将一对变量的关系由相关性拔高到因果性。这道题目仅仅是普通的因果关系。
核心词的重要性,主要成分优先表达
mark
答案不是6吗?
句子主语:the survival of……,谓语动词单数,排除ab。
观察未划线部分but also by,保持平行,排除cd
e correct
**句意:The steel industry has changed radically...,as...companies...that...have greatly downsized,...
钢铁工业完全改变因为xxx的公司已大幅减少...
• "with" is followed by a noun (or noun + modifiers), and NEVER by a complete sentence.
• "as", in this context, connects two complete sentences.
• ,such as xxx, 直接忽略
感觉解释有些问题,补充一下Ron大神的吧
关于A 错主要错在parallel:
the most black-and-white error in (a) -- and the one you should be most on top of, given the importance of the topic -- is its lack of parallelism.
"... and resulting" isn't parallel to anything, so that choice is wrong.
*with用法无错,但句意有错, eg"UNTIL an injury HEALS"无意义
(remember—you should not even look at the answer choices until you understand EXACTLY what the sentence is supposed to mean, and EXACTLY what each word/phrase/group of words is supposed to DO.)
关于D 的in which:
To date, GMAC has only used "which" to modify two kinds of things:
"- Noun
"- Noun + prep + other noun
"... , in which..." (like "... , which...") can modify (i) a noun, or (ii) a noun1 + (preposition + noun2), where the stuff in parentheses modifies noun1.
this is also "noun1 + (preposition + noun2)", with noun2 = "cuts and sprains".
that作为代词只能指代单数,those指代复数
