那就听取Jojo的意见,不去想PREP数学的事了,本来偶这数学极差的人也不该去碰那个壁的,嘿嘿!刚才还在看GWD数学的讨论呢。

其实偶每天的效率是相当~~的低,最近这些天几乎都是差不多的工作:上午-逻辑大全一套,作文或者数学少许;下午-GWD一套(有时做GWD数学,有时不做。偶怎么下午除了做题就没干别的呢?下午好几个小时常常不知道溜到哪里去了!!!);晚上-分析GWD一套+数学JJ。就没时间了。。。

(如果每天都看一点数学机经,既保持数学的感觉,又不至于最后犯傻吧?对偶来说一天一个小时用来做JJ差不多够了)

其实偶实在不愿意写作文,今天就没写,太难受了!!昨天一篇都好不容易快凑完了,结果因为打字太快,电脑自我保护关机了!晕!气得我就没再理它。

现在觉得每天应该抽一点点时间回顾一下原来的OG语法总结,再复习四篇GWD阅读(这个总是坚持不下去,一开始还想8篇呢,简直是作梦)。

晕! 你打字能快到关机! OG 11 DS 我觉得值得一作,不过闹闹数学看来比我好。

Scientists have made genetic modifications to cotton to increase its resistance to insect pests. According to farmers’ report, the amount of insecticide needed per acre to control insect pests was only slightly lower for those who tried the modified seed than for those who did not. Therefore, since the modified seed costs more than ordinary seed without producing yields of higher market value, switching to the modified seed would be unlikely to benefit most cotton farmers economically.

 

Which of the following would it be most useful to know in order to evaluate the argument?

 

  1. Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed.

  2. Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops.这个选项最不好的就是和other crops比较,如果是cotton比,这是最好的答案。但看了很多解释都说modified cottom是包含在其中的。这样,b就对了。
  3. Whether for most farms who grow cotton it is their primary crop

  4. Whether the farmers who have tried the modified speed planted as many acres of cotton, on average, as farmers using the ordinary seed did.

  5. Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide. 原文说了从amount 上看只低一点,因此我就排除了

这是一道争议题,我觉得b,e都有可能,想了很久。其它都是无关选项。

  4. Whether the farmers who have tried the modified speed planted as many acres of cotton, on average, as farmers using the ordinary seed did.

  5. Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide.

B, D, E 争议, 我觉得B other crop 无关,D, E 都行,因为都是insecticide 总量和 per acre 单位量的问题。哪个对呢?

这题比较分特,偶米啥看法,大概是觉得B比较好一些吧,就把当时从讨论贴里copy下来的东东贴给你看看咯~

原文已经说了新的东东只比旧的东东省一点点农药,单纯从E是推不出改后用农药多少,改后用药多少是从原文得出E只在为何改上讲,除此之外什么也没说,更不能得出任何对算经济账有用的信息,所以不妥。

 

B则隐含一个小问题,那就是B中的other crops 能否包括modified cotton(注意只要包括就可以)。我认为应该包括。other 修饰的crops用复数,other在这里的意思为:the rest used to refer to all the people or things in a group apart from the one you have already mentioned or the one that is already known about. 即除你已知道或提到的之外的全部。对B选项已经提到的是ordinary cotton,除ordinary cotton之外的全部庄家,当然应该包括modified cotton。其实B要表达的意思是ordinary cotton用的农药是最贵的,直接告诉你比modified cotton太便宜你,这不是ETS的风格,他们总要绕着说

 

具体到本题,原文是在算经济账,算算新旧品种那种合算。跟其他因素无关。新品种省农药但种子贵,旧品种种子便宜但用药多。要严格比较那种在经济上合算,是必须将有关的价格因素进行对比,多多少,少多少,但原文没有,这就是为何该题不是问ASSUMPTION的原因(必须排除其他可能)。问题问支持反对,满足两个条件就可以(当然MOST题时存在程度的问题)。对B选项,如果旧品种用的农药比新品种贵,这在更换新品种的经济账上加了一个筹码,更换经济合算的可能性增大,起支持作用。反之,则在更换新品种的经济账上减了一个筹码,更换经济不合算的可能性增大,其反对作用。所以B正确。

fanfan,我现在只做了og11的review,还没有看紫色的。载review,我觉得你说的新题都是对的,除了21,35,62是og10上的旧题外。

我发现你们的进度都很快,我一天只能做一套gwd,然后要用一天的时间看解释。这么办?这和我做题的速度一样啊。

今天作了gwd13,错了16个,超时16M.还没有看解释。今天肯定是看不完的。

jojo 你说得真好,很具体。pf,pf.

我在看这道题的讨论贴时,好像还看到了你的帖子。

偶的破笔记本是东芝的,运行过快时会保护性关机,有时候聊天打字快了也会突然关机,很烦呢!

不知道OG11的DS和OG10的一样不?偶N久前做了一遍OG10的,大概还有几十个遗留问题没解决呢,抽空再看一下那些不会的题。数学太吓人了,偶做GWD都没能力提前完成的。。。。今天的GWD数学错了4个题,可以有资格看JJ了哈,嘿嘿。

小case别着急,我一开始做前10套GWD的时候,当天都看不完解释,第二天还得继续呢,当时也是一天中别的事情都做不了。很快你会适应的,况且后面这些题的解释也越来也少了。(其实偶觉得自己前10套做得不够认真,分析得也不够认真,否则怎么会没进步呢?)

今天下午是CD16,超时3分钟(偶再改改最后11题狂看时间导致不专心的毛病,应该可以应付pace问题了,希望),语法错1,逻辑错3,阅读错8!

唉,阅读啊阅读。。。。Jojo。。。。。。

闹闹别急,做一下GWD阅读分类突破一下,量大概不能太少,可能是瓶颈了~

另外,给点心理暗示自己吧,可别惧了它!~

服了小case 和jojo, 我改选B.  我做逻辑有个大毛病,读完原文就直奔和自己想的一致的选项,特容易误排除正确的;而对那些读完没感觉的逻辑,只好逐个看选项,大家有觉得选项有长又绕,得边读边想吗?我这样至少花3-4m,你们每个选项都读吗?

昨晚CD11-天山3, 错12个,SC爆炸了错8个,CR3, reading 争气只错了1个,有一篇读了4m25s,两篇4m5s,一篇读了6m25s,感觉有些active reading的意思。 闹说的没错,分析阅读很有用,我就是模靠前分析了CD10巨难的阅读。靠阅读抢时间,这次超了5m.

小case, 详细分析GWD没错的,不要太吝惜时间,不过模靠时pace还是紧要的,多练练,希望咱们就像闹闹一样了。

谢谢Jojo,GWD阅读分类突破是啥呢?怎么分类??

今天问大家个GWD的数学题吧,也当练习一下阅读了,这个题实在是看不懂

Q28:读不懂

This year Henry will save a certain amount of his income, and he will spend the rest.  Next year Henry will have no income, but for each dollar that he saves this year, he will have 1 + r dollars available to spend.  In terms of r, what fraction of his income should Henry save this year so that next year the amount he was available to spend will be equal to half the amount that he spends this year?

答案是:1/(3+2r)
