i chose A

opinions are welcomed

#1 觉得B 比 D好，因为首先which 我觉得是修饰 AM-1的，只有它才是effort的一部分，但是它同时也是new satellites的一部分。而不是全部的new satellites都是effort的一部分。。。。。umm..这样解释有点牵强。。听听NN怎么讲吧？

#2 这道题目考时态，between time1 and time2应该用 一般过去时。因为动作在time2之前就结束了，没有延续到现在，所以present perfect tense不妥。

#3我赞成A~   D一看就不对，although是conjunction需要连接两个句子，但是D跟了一个ing，一眼就不对。还有后面用的是company's sales，最好还是用sales of the company

同问，我也选A。
D的后面那个with说不通。

#1. D

#2. A   between 1876 and 1904 should modify construction rather than sewer system

#3. A  agree LZ

第一题：

应该还有个单复数的问题吧.that 后面的谓语动词是否是单复述由它修饰的词决定。

one of sth + 复数

the one of sth + 单数  这是BY的书上这么说的

这里是 one of the many new satellites 这里的前面有个the 虽然不肯定，但是我觉得 谓语动词应该是单数，而且出现了that is在句子里，前面又有这样的机构，所以考agreement是肯定的。

第二个考点，应该是which和that的区别，既然前面加了the，在限制性定于从句中，应该是只能用which而不是that。

D选项中an effort for 15 years比较wordy，不如15 years effort 来得effective

第二题：同意LZ

第三题：我认为还是同意答案。

记得BY的书里有关于代词的考点解释，大约是这样的：若主句与从句为同一个主语，则两者主语不能同时用代词指代，但主句的主语为非代词时，从句一定要用代词或者加以省略。

另外还有一句：从句能不用则不能，能用分词则用分词。（大家可以查一下）

我觉得BY说的很对，这就体现了SC的effective，又correct.

所以D选项完全体现GMAT的SC精神，呵呵，我觉得看的很顺眼，

以上请NN们指正，偶正在为SC郁闷中。。。。。

針對GWD4-17個人看法如下:

D的選項比A好,原因是D選項中的having recently added many new restaurants across the country and with its sales increasing dramatically,就是

the restaurant company has recently added ....的簡化,省略主詞將子據改寫為分詞形式,同時and左右個搭配一個由名詞開頭的子句,最為精簡且意義表達上最清楚

A的選項Its重複出現過於累贅.

my resaons:

1. "a 15-year effort "is precise and concise and "effort to do sth" is quite standard; "that  are" modifies satellies are doable;

    so why did you use attributive clause to modify "effort"?

2. if the phase" construction of" can be separeted, then i agree the answer A

3. i still stick to A.  "Although " regulaly is followed by a whole sentence except the subject here is the same as the following sentence.

   the second sentence has the subject of   " sales" which is not the subject of the first one. Then the A expresses the whole sentence and is correct.

第一题：

关于定于从句的使用，在OG里：比如有个选项其他没有错，他的解释会说这个选项wordy,因为把从句省略为分词结果，会effective些。

另外在BY的书里，有一个知识点是特意说明关于从句的省略问题。LZ不妨看看？

昨天我说的“这里是 one of the many new satellites 这里的前面有个the 虽然不肯定，但是我觉得 谓语动词应该是单数，”

不肯定，只能请牛牛们鉴定，昨晚回家查了BY的书，也没有看到关于这个结构的一致性问题。 怕误人子弟，：（

第二题：

我还没有做过GMAT的阅读和其他的很多资料，不过看过杨鹏的长难句，那里面的句子，很多的都是把一些词组活生生的才开来，中间会插入很多不同结构的修饰，所以我看这个选项的时候也觉得挺自然的，很顺。另外杨鹏的书的前面有个说明，里面有句话，说：大家在用此书时，不要想着这个句子是不适语法错了，因为肯定是不会错的。

所以我觉得把一个词组才开来，分得老远，没关系把，只是他们故意增加了我们阅读的难度。：）

第三题：

更正昨天说的，两个的主语是不一样的。：（  昨天没仔细看

不过，始终觉得D选项看起来顺眼，主句和从句里的its都是指 “the restautant company的”，D选项比较clear，而A有点unclear。

仍然认为，从句能不用就不用，尽量省略，以较少的单词在合适的位子表达最精确的意思，呵呵。

请牛牛们指教了，刚开始SC，大家多讨论讨论，一起加油~~~~~~~~~~~

第三题：

its in D has no reference. please note that the form of 'the restaurant company’s sales at ***

having recently added many new restaurants across the country    has a wrong logic reference 'the restaurant company’s sales'

仍然认为，从句能不用就不用，尽量省略，以较少的单词在合适的位子表达最精确的意思，呵呵。
