(E) nine set in Pittsburgh's Hill District, an African American neighborhood, and each have their setting
为什么E不对？还有其他几项？而是选B？

Answer 1

A项就是原句所以直接排除。SAT就是有一个选项是题目重现啊。

我选。B项 如果你对each one of them 后面接复数 are 有歧义，帮我一起问问你的新东方老师是不是打印错误呵呵~
不过这里有一个www.tfd.com/each 关于each的单数复数问题的解释示例。

The traditional rule holds that the subject of a sentence beginning with each is grammatically singular, and the verb and following pronouns must be singular accordingly: Each of the apartments has (not have) its (not their) own private entrance (not entrances). When each follows a plural subject, however, the verb and subsequent pronouns remain in the plural: The apartments each have their own private entrances (not has its own private entrance). But when each follows the verb with we as its subject, the rule has an exception. One may say either We boys have each our own room or We boys have each his own room, though the latter form may strike readers as stilted. · The expression each and every is likewise followed by a singular verb and, at least in formal style, by a singular pronoun: Each and every driver knows (not know) what his or her (not their) job is to be. See Usage Notes at every, they.

就是说如果Each + 名词复数 就加复数， each (one) of + 名词复数 就加单数。这个名词是We时例外，单复数都可以加。

所以这B项除了这个are 以外全部没有问题。
那个them 可以理解为：nine 前面有个分号 semicolon 后半句独立，并且不用在nine前面加连词。them也不用which 因为分号后面独立成句不去修饰前面任何东西。

C项两个动词不平行啦 being set 后面又用 is set 要用is set 就变成独立主谓结构，就要加连词，又没有连词

D项 典型的动词改成形近名词的错误范例 is set in是设置在某个位置的意思，settings 是安排，场景的意思，只要一个安排的意思不太一样有歧义就可能和is set in 不同义。排除。

E项是的数字 nine 、each 是同位语结构，因此其他部分全部平行。nine后面的set有多余的嫌疑，关键是each 和 have their 不太搭。好像是 each has its比较通顺吧。单复数其实语法是不限定的，只要搭配正确了就行。而且又有这个多此一举的setting!! 不过句子的意思是说每一幕都有单独的场景，那既然单独的就用单数好像好一点。。

Answer 2

ugust Wilson's Pittsburgh Cycle consists of ten plays, nine of which are set in Pittsburgh's Hill District, an African American neighborhood, and each of which is set in a different decade of the twentieth century.
分析一下这句话的句子结构就不难看出其它选项的错误：这是一个并列复合句，主句是
August Wilson's Pittsburgh Cycle consists of ten plays ，后面由 and 连接两个并列的由 which 引导的定语从句表示“比赛”的时间和地点，先行词（被修饰语）都是 “plays”，B、C 、D 答案中 them 不能起到引导从句的作用。如果将 plays 后面的逗号改为句号，则 B 答案成立，但 are 必须改为 is。E答案中最明显的错误是“ and each have（应该是 has）”，当然还有其它问题。
不能谈的太多，如仍有疑问，欢迎追问探讨！追问

对不起！这道题目粘错了！！！答案是另打上去的！！这道题应该选A，我想问的是这题
5. In some places the sea is unusually rich in nutrients tiny plants multiply there, turning the water green.
(B) Where the sea is unusually rich in nutrients, tiny plants multiply
(E) Tiny plants multiplying in the unusual nutritional richness of the sea

追答

你好，这个题目的答案我选 B
理由：答案 E 中有两个现在分词短语，但没有谓语动词。
In some places where the sea is unusually rich in nutrients, tiny plants multiply, turning the water green.（where 在此引导一个地点状语从句）
In some places ，tiny plants multiplying in the unusual nutritional richness of the sea, turning the water green.

Answer 3

E里面each是后面要加三单的不能是have而且和原句相去甚远
D/C完全就是混乱的句子，在SAT语法部分一定不会选这样的句子
A里面有conj也就是说后面必须加完整句子，但是后面关系词用的是which，也就是说缺少主语了，所以应该是两个them，选B
