看清楚题目的表达,第一个条件是and,就是总乘客里的20%带车往返,第二个条件是有往返票的乘客有60%是不带车的,所以往返乘客中带车的的比例是40%,由此可知,往返票占总数的50%
注意审题说到的是:“casts the most doubt on the **WISDOM** of the magazine's new policy as a way of pursuing the intended effect?",如果从wisdom这个角度考虑,E选项通过引进新技术即可解决问题,也不会使得sellers卖rare wildflowers的revenues下降,相较于直接不宣传不卖是更好的方法,起码“双赢”了嘛
条件2:2n的因数是n因数的两倍
2的引入使2n有两倍于n的因子,说明2不是n的因子。
所以n一定是奇数
【结论】If kn is divisible by twice as many positive integers as n, then n isn't divisible by k.
问0.2A+0.1B+0.1C>0.15(A+B+C)吗
(1)12+0.1C>10.5+0.15C吗?
c<30吗?
肯定对啊,因为c是最便宜的,B都只有20了,C肯定<20
所以(1)充分
(1)(2)
A a0→a1
C c0→c1
(1)a0=1.1c0
(2)a1=1.2c1
问(a1-a0/a1)➗(c1-c0/c1)
化简得 (1.2c1-1.1c0)/(1.2c1-1.2c0),还是算不出!!
C错 “ Because women were seen as belonging to the private rather than to the public sphere” 是解释第二点中的细节
To increase the number of fossils available for research是立法的主要目的。
然而A选项中如果许多化石被非买卖者占为己有了,显然这些化石是不会进入研究机构的啊,所以不懂为什么可以排除A。
考察点,which的跳跃修饰+主谓一致+名词/动名词辨析
Use negation method:
a) In Siduria the rate of fuel consumption is rising MORE quickly than the rate of fuel production -> negate the conclusion ( production cannot catch up the demand)
b) Domestic production of natural gas is NOT rising faster than is domestic production of oil in Siduria. (Doens't matter, and if oil production increase, it would actually require less import)
c) FUEL other than natural gas is expected to be used as a replacement for oil in Siduria. (Irrelevant. and if it is, require less import)
d) Buildings CAN be heated by solar energy rather than by oil or natural gas.(Irrelevant, and if it is , less import of oil required)
e) All new homes that are being built will NOT have natural-gas-burning heating systems. ( Irrelevant, how many new homes are there that will affect the total consumption of oil?, the oil consumption by this new homes might remain the same)

第一句黑体是GOAL,而ill conceived的是plan, 所以可以直接排除ABC, 因为argument并没有说GOAL is ill-conceived / can be attained.
E, Goal 并没有被认可 , 所以也可以排除。
argument主要关注在解释为什么high success rate 不代表他们是 good fund-raiser/doing a good job
good fund raiser = able to expand the donor base
A; 开发新donor base 的成功率与其他学校哦一样 ,所以即使他们联系过的潜在捐款者成功率比较高( 比如说: 联系100个,80个捐款,其中是个是新捐款者;其他学校联系100个,70个捐款者,其中10个是新捐款者),也不能表示他们是good fund raiser that good a good job.
C : 表示大部分的捐款都是来自之前捐赠过而不曾经过联系的人。但是这不能表示什么,因为本argument重点在成功开发率为主,而大部分的捐款者是过去捐赠过的人并不能表示成功开发率的多少。
准备12月考,望妄忘
Conclusion : Nevertheless .... (倒数第二句)
所以, ABC,可以排除 (因为第二句黑体不是结论),而是用来解释Conclusion.
E: 第二句子没有用来证实第一个句子是对的,而是表明第一句子不能用来表示50% 以上的case是虚假的。
D.with放句尾時會修飾前一句的V或O,因此在此處不恰當
就相当于是用五根木棍(两横三竖的)排列组合:|-|-|
第一段重点词can work successfully in conjunction
第二段重点词cannot simply be grafted
qualify限定,第一段,缩小范围,不是反对第一段!!
读题下来发现A没有硬伤,留着;BC都存在通过一个问题, and前后的成分不平行,排除BC;句子前面没有划线部分已经说了 them,那就不可能用单数,排除D;读E发现E也没有硬伤,最后在A和E中间纠结:
Ron关于A为什么错的解释有二:
第一,中间的providing...and milking...从语法上可以对,但是意义上不对,因为用Verb-ing的情况必须【同时】满足两个条件:第一 Verb-ing的主语是指前面句子的主语;第二Verb-ing是表达的要么是前面句子的结果,要么是同步发生的事件。Ron认为第一个条件满足,第二个条件不满足。我觉得解释为“同步发生的事件”是可行的,没毛病(Farmers takes care to keep..., providing...and milking...),可能是因为我理解的这个“同步发生”跟Ron说的不太一样,他说的同步,必须是极其明显的同步,比如说Tom talked to his mother on the way to school, eating the bread meanwhile.
第二,他认为从native speaker的角度来看,这个are producing的用法非常akward,原因是正在进行时的时态emphasizes the ongoing nature of an action; it specifically emphasizes that an action is taking place, right now, as we speak.。而这个句子是在表述某种状态,"to state an eternal truth. for that, the present tense is used".,用正在进行时不合适。
*Ron说还有一个小错误:note that you also can't say "THE holstein cows", unless you're referencing a particular, specific, known group of holstein cows (something that you clearly aren't doing). since you're talking about holstein cows in general, you don't use the article "the".
