Harder Question.

同位语加并列结构

正确选项D.[speeds of up to 150 miles per hour] and [heights of up to 200 feet]会不会显得很wordy？？
可以说成up to 150 miles per hour in speed and 200 feet in height 吗？（但是没有这个选项微笑脸）

It is also awkward in introducing the superfluous end up

needle layer is less precise than the more standard layer of needles, which makes it clear that the layer is composed of needles rather than being, for example, a layer of a needle. From where is not the correct form, because it is redundant in using two words that express the idea of location (from and where) instead of one.

So much as is not the correct wording to express the upper level of a variable amount; as much as should be used instead. Also, although the singular a sperm whale can be used to refer to sperm whales generally, the plural their needs to refer to the plural sperm whales.

Although this sentence, as presented, uses the conditional or past verb form could, it is more plausibly intended to make a general statement about the actual behavior of a species, a statement that holds in the present day. For that purpose, the present indicative can is preferable.

这个题的考点是什么？

我的理解是：为了保证不过度控制（即不要控制那些无害的effluent), 就要保证现在控制的substance都是实实在在对环境造成破坏的。即B

would和have to组和而成一个完整的“would have to”，这是一个不可割裂的整体！表示一件应当做但没做的事，表示“现在（注意是“现在”！）应该如何，但事实与之不符（或相反）”。我们可以看到这里有明显的背反：原题中有more than now，答题中有更明确的more than they do now，均已构成明显背反，所以选D无疑。但是要注意，由于have to本身就有“应该”的意思，在上下文中如没有出现明显的背反或明显违背公认的事实及常识的时候，不应使用“would have to”，用“have to”既可。
必须注意，would have to的出现在英语中有些限制，那就是要求本句或紧邻的上下文中如有“目前并非如此”之类的明确表达或与事实及公认常识明显不符，否则宜用have to而不是would have to。还有在强调“必须性”时，比如你说“法律规定，每个儿童都必须受教育”，尽管你知道有很多失学儿童，可这里是强调必须，就还得用have to而不能用would have to。

a vantage point前面没有任何一个词是point，所以不能做同位语

错选B，B中同时削弱了两个说法（至少没有加强其中一个）。只有C是加强了rest（equal pause），削弱了视觉（看见了prey逃走后加速）。

E小麦最早发现的种植痕迹在strip那里→曾经很多地方都有它的种植痕迹→现在只有strip这里有wild e小麦了。推断：strip是最早的种植e小麦的地方。加强：strip的环境自古以来没怎么变过。D选项可以解释这种特定环境是e小麦需要的，如果strip环境一直没变，则可以推断以前wild e小麦也是在这里出现的

其实已经给了不认识单词的我一个机会。应该是在一个extreme condition ，therefore 叫做extremophiles ，这两个并列。看词根就知道了啊！

C. addressed the controversy不对，只是shows that the debate....
D. analyzed statistics不对，都是大概用词，没有给过具体数据分析
