老师 明白为什么选C 但D选项不是很理解 为什么不能反驳呢 是不是因为不能单纯上来反驳结论 而是要用推理 谢谢老师

第二段说resin功能到底是驱赶还是吸引虫子？Fraenkel说：一开始nonspecific，后来specific，但是，一些虫子会overcome repellent，变成attracted。这样：rein会导致虫子feed on those plants。然后提出specialized discipline of chemical ecology，后面定语从句用and连接了plant antiherbivore chemistry。
做题的时候，从关键词plant antiherbivore chemistry开始，原文能看出这个和前面的东西是并列修饰一个什么ecology的，再往前找，原来是一个什么ideas导致了这个ecology，再往前，就能看到feeding相关的东西。这时候已经晕了。

解题错误

判断题 可以不可以

坑：positive integer

C：人们应该避免食用人工脂肪。
P：人工脂肪吸收必要的维生素，阻止这些维生素被人体所使用。

A选项如果是肯定的话，即摄入维生素可以弥补人工脂肪带来的不利影响，那么推出的结论是“人们可以食用人工脂肪”，否定了原结论。
A选项如果是否定的话，即摄入维生素不可以弥补人工脂肪带来的不利影响，那么推出的结论是“人们应该避免食用人工脂肪”，肯定了原结论。

这道题的关键是要找到columnist position到底是什么，注意不是artificial 发fat has a serious drawback.

wrong: i've always wanted to jump out of a plane, but i've never had the chance to do it. --> this is wrong because the only possible antecedent for "it" is plane, and it doesn't make any sense to talk about "doing" a plane.
correct: i've always wanted to jump out of a plane, but i've never had the chance to do so. --> "do so" = jump out of a plane.

perhaps the most common usage in which you'll see this is "do it" vs. "do so"

he rule i like to use here is this: if it's not a specific NOUN that can be replaced by a PRONOUN (usually "it"), then use the all-purpose replacement "...so".

曲解题意

choice a does just that: it says that the new pollution-control equipment will create a new market, which will then offset the loss of the old markets.

the passage goes from
'the loss of some export markets'
to
'annual exports of ... goods will ... diminish'

that's a logical leap. in particular, the hidden assumption is that no other export markets will step up to take the place of the ones that will be lost. if we can find an answer choice that contradicts this assumption, we can weaken the argument.

坑：cubic

老师这边AB的without可以看作定语吗，由于定语的就近修饰原则，withoutadequate amountsof sleep修饰people's newly acquired skills,但是skill肯定是不会缺睡眠的，所以错。这种解释合理吗？

英文表达好奇怪，加一个however，以为是说和前面的推断：没人受影响相反，有人失业，问为啥。。想骗了。。

推断题目是必须能从文段中100%推出，任何小于100%可能性的答案都不可以。当然更不能加入任何主观信息和任何文章中没有提到的信息。
本题，最重要的是文段中的第一句话，这句话读懂了，自然可以选出A。
本文有三个facts：
Fact1:Parasitic wasps lay their eggs directly into the eggs of various host insects in exactly the right numbers for any suitable size of host egg. 寄生蜂可以根据寄主蛋的尺寸，下刚好数量的蛋。
这也就是A选项所说的，可以根据寄生蜂的下蛋行为来判断寄主蛋的尺寸。
