第四遍错。。。呵呵哒啦
我真的不懂B with milky sap是个插入语ok 忽略不看。 后面的that修饰的是谁？难道不可以是euraisa吗 而实际应指代a herbaceous plant 所以不会显得指代有误吗？ 对c选项，我觉得后面的displacing grasses是和having milky sap并列 而不是和gives mouth sores并列，这么理解为什么不对呢？

这种题。。。真的太虐了

C选项-A surge in new home sales and a drop in weekly unemployment claims suggest
that the economy might not be as weak as have been previously thought by some analysts
that从句还原后the economy might not be as weak as economy have been previously thought by some analysts
have应用has

那c的as well as gesturing 是对的吗？ as well as +doing 是一种用法，但是这里需要和made hand motion的时态平行吗？

没说相对价格高低，所以不能判定为相关因果

请问为什么A不对呢？他说V卖出4000，然后租的比卖的多，那不就说明V 的租赁抢了C的租赁吗？

提问！老师，为什么B不可以呢？B取非之后不是可以削弱方案的可行性吗？取非之后是，许多manager仍然认为只有管理层才能做决定，那就使得方案没法儿实行，那员工的productivity也不会提高……

Ron给的例子感觉也可以解释，信被写的时间和数量超过没有关系。

my brother, who ate bagel bites for breakfast every single day of his high school career, graduated in 1994. --> correct; his eating bagel bites had no impact on his graduation date.
my brother ate bagel bites for breakfast every single day of his high school career, graduating in 1994. --> incorrect; these are two unrelated observations, but this construction erroneously implies some sort of relationship.

"would" can be used as a past-tense form of "will" -- for instance, i know that we will win translates into the past tense as i knew that we would win -- or to express a hypothetical situation that isn't true.

the easy way to eliminate (b) is to know that "would" is incorrect.

"would" can be used as a past-tense form of "will" -- for instance, i know that we will win translates into the past tense as i knew that we would win

the scientists did the studying., so, the modifier about studying should be as close as possible to "scientists".
("by the study of..." is problematic idiomatically as well.)

Still no, because "enabled" should still be used to describe an actual ability. I.e., if you wouldn't say that someone/something is able to do something, then you can't use "enabled" to express that idea, either.

many customers intending to buy our wine will mistakenly buy theirs instead.
意思是想要买MW的人会错买。

C 想表达的意思是DW做广告突出label，大家都认识DW，所以会买DW。

* "with states opening..." is incorrect. when you have an -ING WITHOUT COMMA modifier, like this one, it's a RESTRICTIVE ("essential") modifier. this means that we're only talking about those states that are "opening their utility markets to competition", the implication being that only some states are doing so. the intended meaning is better conveyed by "as states open..."

只关注语法了，没关注意思，C的语法应该是没错的吧，但是逻辑意思是错的。

"between 1990 and 2000" describes the entire sentence that follows.

if you want this type of modifier to describe a noun, you have to put it after the noun.
