注意本题有一个隐含的条件是：人吃meat也吃grain
所给出的条件：需要several pounds of grain来生产one pound of meat
所以meat、grain和人的关系是：①人comsume meat+grain ++ ②grain produce meat
现在的情况是：meat的消费增加（即produce meat使用的grain增加），但grain的产量不变 -- 要进口grain或meat
假设题要找gap：题中给出的情况符合逻辑链②，那么逻辑链①必须保证不变，也就是说人们如果减少自身对于grain的消费，那么不一定需要进口（也就是对于E选项取非），发现会影响结果！

假设一个人高度1m， 那么在painter眼中这个人是2m，于是在他的画中人是2m高； 然后当他看自己的画时，在painter眼中人就变成4m，这明显跟painter印象中的“人是2m”这个事实想矛盾，那他就会发现这个问题。这就是C选项所说的elongated figures in his paintings would have appeared to him to be distorted

错选b：并没有全文反对。实际上开头写的很多人认为it是好的事物，文章最后也同意了。

这家公司好可怜 电话市场整体上升了 它傻白甜的想跟上这个趋势 但是去年降价都卖不出去呢……
Gap:电话销量总体上升≠某一家公司销量上升
只能推断第一句话是整个行业的。。。我在做题的时候没看仔细，以为是该公司去年的情况，结果做题时，觉得所有选项都是错的。。。

解题的点就是这句啊：avoid excessively restrictive controls. 感觉这道题就是有一点“过犹不及”的意思，怎么样做才能避免过度的限制呢？就是你必须保证你要控制的这些东西必须会引起污染，不然就是excessively restrict control了

D选项里面的written while he lived in France在本选项中是非限定性定语从句吗？没有引导词啊；那如果是非限定性定语从句的话，表修饰有什么不对吗？

B. Inhabitants of the area around Lake Champlain claim sightings of a long
and narrow “sea monster” similar to the one reputed to live in Loch Ness,
which, like Lake Champlain is an inland lake connected to the ocean by a
river.

D: 时态不对，不能用have been killed

deterring to the nuclear industry is not correct, as deter is a transitive
verb and requires a direct object

B：red giant stage 是 depending 前唯一的名词，会被认为是指代的这个，句意就不对了

underwritten by, 如果修饰program那么就违背了本意

like+ 名词，
As 引导一个句子
不知道啥能和skater比较

(hopefully)however, it must be used at the
beginning of a sentence or at the beginning of an independent clause, and be
set off by the use of commas

The use of like incorrectly implies that electromagnetic waves are a type of

overlook不能加that
