cedar比steel和timber frame 的强度大，有joints and nails，cedar很灵活
既然是这样DE就去掉，因为变成了timber frame incorporates。
然后C的 steel has 应该是steel does B里面的used in them的them要找很远才能找到buildlings

体会C选项带来的歧义

After coma, “wings” is required because pronoun “them” is present towards the end of the sentence.
For pronoun “them” a clear antecedent is needed. This antecedent will be “wings” which must be placed after coma.
Hence, A, C, and D are incorrect. Moreover in C, instead of adverbs (smoothly and perfectly) adjectives (smooth and perfect) have been used.
Furthermore in D, “smooth and perfect manner” mean “smoothly and perfectly” hence, D is wordier by one word than the sentence was required.

If what immediately follows not only is a verb phrase, then what immediately follows but also must also be a verb phrase. And so on. The sentence here correctly uses the not only . . . but also . . . construction: what immediately follows not only is a verb phrase (disputed the common notion . . . ), and what immediately follows but also (questioned whether he drank at all) is a verb phrase as well.

All the possible answer choices here use the construction not only . . . but also . . . We can easily eliminate the choices that use the construction inappropriately. The construction is used appropriately only if what immediately follows not only and but also are grammatically parallel. For example, if what immediately follows not only is an adjectival phrase, then what immediately follows but also must also be an adjectival phrase.

flat既可以是adv也可以是adj词性，都是平直的；flatly是adv词性，是断然的意思；这里选flat

C. Correct. Both clean and fast-growing are adjectives and are therefore parallel; they can correctly be conjoined by and. This choice creates a sentence with the relative clause that pay . . . workers. Notice that the sentence has another relative clause that are clean and fast-growing. This relative clause parallels the other one. Using and to conjoin these two clauses, each modifying industries, is logical and correct.

E. The adjective clean is not parallel with the verb form paying.

...percent of x 单复数取决于x是可数还是不可数

E. This choice does not use not only . . . but also . . . correctly, because what follows not only is not grammatically parallel with what follows but also. What immediately follows not only is an adjective, whereas what follows but also is a verb phrase. Furthermore, could be dried is more idiomatically correct than able to be dried, as is used here.

前提 烟雾提供了正离子 结论 所以多出来额外的正离子一定是本来就存在于雷云中的。 那这个额外的正电子是不是雷云中存在的呢， 烟雾消失的时候 ，多出的正电子相撞减少了， 说明是这些额外的正离子不是本来就存在的，它们随着烟雾消失了，至于怎么消失，不在不需要考虑， 只是一定存在他因造成的。

C. This choice correctly focuses on the increase in consumer spending as a whole. However, it strings together too many adjectives; to make the sentence clearer and more readable, it would be preferable to state increase first as in choice E.

……的增长我们通常说 an increase in sth，比如本题 消费支出的增长通常表达为 an increase in consumer spending

B: would have done表示与现在相反的虚拟 比较对象错误

A. which引导的定语从句修饰其前面的toys，但逻辑上是Television programs developed in conjunction with the marketing of toys这个事件prohibited by federal regulations，A错误。

C: developing不能正在繁荣

date back to idiom

选项C：动名词短语cooking food with fire需改为名词短语the use of fire to cook food，这点错误同选项(A)。另外，分词短语explaining hominid features是be dated back的伴随状语，其需要被改为普通的合句。“可以被追溯到什么年份”和“可以解释什么特点”是一件事两个不同方面的属性，应该用合句来表示两者并列，而不能用伴随状语。伴随状语表达的是主从关系，即，两个事件之间有因果或者强弱的关系。

有些同学可能会认为date back应该用被动语态，因为“用火做饭”这件事只能“被”追溯，而不是主动发成追溯这个动作。但这是不正确的。在英语中，有一族的动词学名叫“中动词”，这些动词的特点就是，主动和被动表达近乎相同的意思，例如：
The door is opened.
The door opens.
这两句话都讲的是“门开了”。open就是一个典型的中动词，它的主动语态和被动语态意思相同。还有很多例如read, increase, decline, cut等均是中动词。本题中的date back to，也和上述原理相同， 是典型的中动词，主动和被动同意。

动名词短语using fire to cook food需改为名词短语the use of fire to cook food，这点考查了名词和动名词的区别。用之于本题，可以被追溯到两百万年以前只能是“用火做饭”这个事件，一个事件自然有内置的时间终点（饭熟且吃上饭了，用火做饭这个事件就结束了）。请注意，有些时候，use fire to cook food在表示“属性”的时候，是没有时间终点的，例如：
Q：What is your task everyday？
A：My task is using fire to cook food.
一个人每天的工作肯定是一个属性，属性显然没有时间终点。
