ron：The parallel structures in C are...
promotes blood clotting
does not interfere...
This is the actual contrast that we want to point out.

The parallel structures in D are...
is a substance...
does not interfere...
Nonsense; that's not a contrast.

(C) 正确, a substance that…独立主格结构作为thromboxane的同位语对thromboxane进行解释说明; but does跳过同位语和suffices并列共同作为a low dose of aspirin的谓语动词

RON：the principal objection here is that the meaning is incorrect/unclear: for instance, a 'two-year low level' could mean that it hit a low level and then stayed there for two years.
consider other uses of the adjective "two-year":
a two-year lease is a lease that LASTS for two years.
a two-year recession is a recession that LASTS for two years.
a two-year marriage ... etc. etc.

懂了为啥要加that 不急that就不是一种情况而是变成了一种单纯的生物

老师，我想问一下您之前讲过的背景图的问题，说如果是先发生且长时间发生的事件应该来做背景，从而也就是充当从句成分，主句成分发生的时间较晚且较短。那么从这句话来看，later Elizabeth Barrett Browning was overshadowed by his success这件事情发生的较晚且时间较短，所以该句话应该充当主句部分，而she was considered among her contemporaries to be the better poet than her husband应充当从句部分。但D选项却正好相反，这是否矛盾了呢？

I think C has a problem with the past perfect "had been " .... This would imply that the inclusion happened before the draft. The intended meaning is that the inclusion happened at the same time.

another problem with C is that is not clear who included the call for female enfranchisement, since the sentence is in passive voice.

B 在多年在峰值下运行，DR的制造业现在已经接近峰值；生产不可能在增长，没有更多东西用于出口

infest不是大批滋生的意思嘛？
D不应该是说 老鼠的数量主要是人口密集的地区 吗？

永远是大错误大于小错误 不要用compare lower来判定
Bburning 和 it is 25percent lower 之间缺少连词
Cand两者并没有并列关系
DE which reduces先行词一致的原则必需为单数

第一次买电脑的人买PXC电脑中价格低利润低的。第二次买的都是性能好更高利润的。去年PXC利润大大增长，尽管卖的电脑数量和单台利润没变化。
去年第一次买家买的PXC电脑比例比前年小；因原文说总数不变，单台利润不变，但利润增长，显然可以推知是第二次买家买的高利润产品更多了，第一次电脑比例下降

题干：进口钢铁价格低——国内钢铁行业收到打击——政府采取措施减少进口——国内钢铁企业收到保护——相关行业就业率提高
C：国内制造企业面临激烈的竞争，钢铁是原材料成本的主要构成——如果政府采取措施减少进口——国内制造企业成本上升（价格）上升——>可推出会销量下降——国内制造企业就业率降低； 削弱；

错选E：再仔细看下，E的K国钢铁企业工人工资和其他出口钢铁到K国的工人工资没有大的差别；并不能影响国外进口到K国的钢铁价格低这个事实，也不会对销量有影响，更不会会就业率有影响了

A each of which 是定从就近修饰animal but组成的应该是群落
BTHEM 歧义
Deach of them 后面应该跟着单三

所以比较 g-r、h-s，判断是否g-r-h+s>0

橘子堆一堆
最下面一成是长方形状的，3行，每行5个橘子
倒数第二行：每个橘子都要放在4个橘子上面（只能放8个）
倒数第三行：每个橘子还是要放在4个橘子上面（4个倒数第二行的橘子）
那就只能放3个

less 与 fewer的考点老是注意不到，没有下意识形成

the present- perfect, passive
verb describes the prior condition have been given . . ., and the future tense verb
will be describes the outcome the workers can expect. The idiom reason to believe
succinctly describes the assurance given to workers.

This sentence asserts that a court decision has qualified a 1998 ruling. It then goes
on to explain the series of conditions stipulated by that ruling: workers cannot be
laid off if they have been given (prior) reason to believe that continued satisfactory
job performance will (always) ensure that their jobs are safe. To express these
complicated temporal relationships, the present tense passive verb cannot be laid
off describes the assurance provided by the ruling;

C The referent for the plural possessive pronoun their is unclear; it is also
unclear what the set of adjectives introduced by though is supposed to
modify. The sentence structure suggests, nonsensically, that they modify
armor plates.

单复数！！！！！未划线部有提示
A. The plural subject cuts does not agree with the singular verb is.

这个答案感觉有问题，如果B是正确的话，说明动名词和with这个结构没有矛盾，所以A也不能因为这个原因被否定掉；而且引起口腔溃疡，是这个leafty spurge的sap，所以that这个定语从句是修饰sap的，
