Question

1. A powerful (advocate to)A equal rights, Belva Lockwood was twice a candidate for president long before the Nineteenth Amendment to the constitution allowed women to vote.
A错了，是因为advocate应该用advocating的形式吗？

2. A great owl (flying low)A across a forest clearing, its (wings beating)B quietly and its ultrasensitive ears turned to the (faint sounds)C made by small (creatures concealed)D under leaves.
为什么A错了？我的理解是B错了，因为beating应该和and后的turned是平行的，beating应该改成过去式。

3.After the (gruelling)A rehearsal, the pianist felt (wore)B out and wanted only to sleep.
B错了，是改成to wear out吗？

4.The heat was already (overwhelming and lasted a week, which duration made it seem) sheer torture.
A.同上
B.....
C.overwhelming and lasted the duration of a week to make it to seem
D.overwhelming, and it lasting a week made it seem
E.....
呃，不是很明白为什么D是对的，还有其它几个选项错在哪。

5.No one (object to)A his company, even though he has made insulting remarks abot almost every member of the (group,when)D he is a remarkabley witty man.
以前做的时候就知道D错了，可是现在回过头来看，我又纠结在A。No one 不是应该接“objects” to吗？

6. In Germany, foresters discovered that trees killed by acrid rain had begun to die four years (earlier, even though the trees had shown no signs of disease then).
A,同上
D. earlier without any signs of diseases shown then
A哪里错了？

7.My grandfather never learned to use a computer, (as he shops) he can accurately compute his grocery bill in his head to within a dollar.
a. as he shops
b. while shopping
c. but as he shops
b错c对是根据v大于doing的规律吧，OC给的理由是while是adv，可是while不是conj吗？

8.Expers agree that permanently modifying eating and exercise habits rather than merely dieting for brief periods (are the key)C (to controlling)D weight.
C咋错了？不是habits are吗？ D为什么对的？是固定搭配？

9. The exchange between the teacher and the student promotes learning far different from that which results (as)C the student listens but does not participate.
C错了，怎么改？

Answer 1

1、首先，advocate不光是做verb“主张”“提倡”的意思，还可以作名词，意思是supporter。第二， advocate的用法错了，(v.)advocate sth./advocate +clause (n.)advocate of/for sb./sth.，这是固定搭配。第三，你没有理解这个句子的结构，A powerful advocate for equal rights, Belva Lockwood was...，在这个句子里，A powerful advocate for equal rights,是一个同位语，是用来详细说明 Belva Lockwood身份的。第四，这个句子不能用advocating，因为前面有冠词 “a”。

2、 首先，turned to the faint sounds不是谓语，而是非谓语中的过去分词形式的定语，用来修饰ears，意思是，转向微弱的声音的超灵敏的耳朵。第二， made by small creatures concealed under leaves也是过去分词形式的定语，用来修饰faint sound，意思是，其他隐藏在叶子下的小生物发出的微弱的声音（concealed也是过去分词形式的后置定语）。所以这些定语们迷惑了你，让你无法看清句子结构，事实上原句是sentence fragment，即两个没有谓语的句子碎片。这样一分析，就可以看出，句子的主干是A great owl flies/flew low across a forest clearing（注意fly的不同变形），而后面都是分词，分别讲述翅膀和耳朵，没有破坏平行结构。

3、wear-wore-worn，应该是felt worn out，单词变形的问题。你应该理解为什么要用过去分词吧。

4、原句简直乱七八糟，which duration的表达很尴尬，先行词指代不清，不够直接，这叫awkwardness 。C选项一样乱七八糟， lasted the duration of a week ，请问last the duration到底是什么说法，一样awkwardness。D选项简洁明了，用两个句子一个and说得清清楚楚，读起来也更顺口。这种题目，建议你大声读出来，用语感来体会。实在没办法，看最短的选项，一般最短的读起来不乱的就是正确选项。

5、我也曾经做过这一题，有印象，可是我记得题目里是no one objects to 。尽管毫无疑问，no one 后面谓语是单数形式，这题很明显是连词用错了，语义不通，应该把when换成because。或者有可能是书印掉了，既然自己知道正确用法，就不要纠结了。

6、很明显时态不对，看见then没有，被腐蚀之后才会开始出现迹象，前面的句子已经用了过去完成时，后面的从句怎么能再用呢。

7、B答案里面的while是副词，因为在这里的意思是，当shopping的时候，表示一个时间段。while确实还可以做连词，但它做连词的时候是表示contrast，后面要接一个【句子】。况且，不要什么v大于doing，会选择C是因为这里需要一个转折的含义，读一读句子，我爸爸从来没有学过计算机，但是，当他购物的时候，他能在脑海里精确的算出账单。两个结构和意义完整的句子，用一个but连接，再好不过了。

8、首先，rather than这个词组告诉你谓语是由它前面的名词单复数决定的。其次，并不是habits are the keys， 而是 永久的改善吃饭和运动的习惯 才是 控制体重的关键。这个从句的主语是一句话，明白了吗。permanently modifying eating and exercise habits 这个分词作主语。你没做对的原因是没有理解整个句子的意思。所以，谓语不是are，而是is。

9、result 在这里的意思是导致。导致的短语是result in ，固定搭配。但是the student listens but does not participate是一个从句，我觉得可能是results that the student... 反正，as在这里是绝对不对的。

Answer 2

1. A powerful (advocate to)A equal rights, Belva Lockwood was twice a candidate for president long before the Nineteenth Amendment to the constitution allowed women to vote.
A错了，是因为advocate应该用advocating的形式吗？
答： A没错，是你答错了。advocate这里作名词=supporter,在句中作Belva Lockwood的同位语。错在to the constitition,改为of the constitution 表示...所制定的修正案。

2. A great owl (flying low)A across a forest clearing, its (wings beating)B quietly and its ultrasensitive ears turned to the (faint sounds)C made by small (creatures concealed)D under leaves.
为什么A错了？我的理解是B错了，因为beating应该和and后的turned是平行的，beating应该改成过去式。
答： 确实是A错了。主句在前，改为flew low. 你的想法有道理，但经不起推敲。关键在turn的用法上。因为和汉语不同，英语中表示耳朵转向什么，不用ears作主语，而用主体（人或动物）作主语：sb. turns a dear ear to ... ，所以只能将its ...ears turned to ... 看成独立主格结构，因而前一个为并列的独立主格结构its wings beating quietly 是对的，且必须是一个独立主格结构。

3.After the (gruelling)A rehearsal, the pianist felt (wore)B out and wanted only to sleep.
B错了，是改成to wear out吗？
答：feel/be worn out 感觉筋疲力尽 wear-wore-worn worn才是过去分词可作形容词使用

4.The heat was already (overwhelming and lasted a week, which duration made it seem) sheer torture.
A.同上
B.....
C.overwhelming and lasted the duration of a week to make it to seem
D.overwhelming, and it lasting a week made it seem
E.....
呃，不是很明白为什么D是对的，还有其它几个选项错在哪。
答：的确应该是D。这是一个并列句。第二个分句是一个“主-谓-宾-宾补”结构，其主语是一个带逻辑主语的动名记号短语。 made it seem 怎么样。
A答案which用错了，因为非限制性定语从句，关系代词应用whose+名词才作主语。
C答案表达完全混乱,make后面也不用to。

5.No one (object to)A his company, even though he has made insulting remarks about almost every member of the (group,when)D he is a remarkabley witty man.
以前做的时候就知道D错了，可是现在回过头来看，我又纠结在A。No one 不是应该接“objects” to吗？
答：原题中本就是objects,不是你看错了，就是出题者失误。when改为because意思才通:“没有人不喜欢和他作伴，即使他对几乎每个队员都说过一些难听的话，因为他是一个很风趣的人。

6. In Germany, foresters discovered that trees killed by acrid rain had begun to die four years (earlier, even though the trees had shown no signs of disease then).
A,同上
D. earlier without any signs of diseases shown then
A哪里错了？
答：A没错，D错了。错在shown then与without之间的逻辑。因为它作为定语相当于说：the trees () had begun to die 4 years earlier without any signs of diseases which were shown then. 到底是显了还是没显？又说没有征状，又说显了。将shown 去掉。

7.My grandfather never learned to use a computer, (as he shops) he can accurately compute his grocery bill in his head to within a dollar.
a. as he shops
b. while shopping
c. but as he shops
b错c对是根据v大于doing的规律吧，OC给的理由是while是adv，可是while不是conj吗？
答：用C，这时一个并列复合句，but后的分句是一个复合句，as he shops是一个时间状语从句，主句是he can do sth.
B错是因为，while shopping, he can do sth. 这是一个句子，与前一个句子不能用逗号并连。A也是同样的错误。

8.Experts agree that permanently modifying eating and exercise habits rather than merely dieting for brief periods (are the key)C (to controlling)D weight.
C咋错了？不是habits are吗？ D为什么对的？是固定搭配？
答：that引导的宾语从句的主语是modifying sth. sth= eating and exercise habits, 看来你的断句还不行。the key to sth. 什么的关键，用to不用of, 初中知识。

9. The exchange between the teacher and the student promotes learning far different from that which results (as)C the student listens but does not participate.
C错了，怎么改？
答： as 改为when
翻译：师生之间的交流对学习的促进远不同于学生只听不参与时所产生的结果。result，不及物动词，表示“所产生的结果”。

Answer 3

1. A powerful (advocate to)A equal rights, Belva Lockwood was twice a candidate for president long before the Nineteenth Amendment to the constitution allowed women to vote.
这里advocate做名字用，表示支持者，那么后面应该跟for，逗号前面等于是个同位语，一位平等权利的强有力拥护者，Belva Lockwood……而且advocate即便做动词，也是及物动词。

2. A great owl (flying low)A across a forest clearing, its (wings beating)B quietly and its ultrasensitive ears turned to the (faint sounds)C made by small (creatures concealed)D under leaves.
这题我说不太好，整句句子的主语是a great owl，所以他后面一定要跟动词谓语，平行的结构我认为其实是主语和its ears，也就是说A应该是flew low, 而its wings beating并不独立成句，他跟在主语后面修饰主语。因为如果如果beat用过去式，则构成与主语的平行结构，前头又有逗号分开，语法上逗号后面必须加个and。没有and则逗号后头的句子不能独立成句，所以用现在分词，而不是过去时。不知道这么讲是不是清楚。

3.After the (gruelling)A rehearsal, the pianist felt (wore)B out and wanted only to sleep.
感觉累垮了feel worn out吧。feel to do sth一般用在感觉要去做某事。比如，I feel to drink. 意思是我很渴，我想去喝水。

4.The heat was already (overwhelming and lasted a week, which duration made it seem) sheer torture.
A.同上
B.....
C.overwhelming and lasted the duration of a week to make it to seem
D.overwhelming, and it lasting a week made it seem
E.....
句子的意思是这样的，温度超高并持续了一个礼拜，这样的情况（即持续一个礼拜过热）简直就是纯粹的折磨。D是完全忠于原句意思的。C的话，有模棱两可之处。last the duration of a week意思不明，是延长了机器（假设是机器过热的话）的寿命一个礼拜，还是其他？如果没有原句，意思比较模糊。另，是the duration make it a torture，而不但是the heat，C的话显然改变了这一点意思。

5.No one (object to)A his company, even though he has made insulting remarks abot almost every member of the (group,when)D he is a remarkabley witty man.
这个指记得以前老师说过no one和each one后头其实是可以跟复数的。我就死记硬背下来了。既然D肯定是错的，那么A就不是选项了。= =|||

6. In Germany, foresters discovered that trees killed by acrid rain had begun to die four years (earlier, even though the trees had shown no signs of disease then).
不明白这里“同上”是什么意思？A的答案跟原句一样？如果是这样的话，那么实在保证其他选项都是错的情况下才选A。A是肯定对的，但是既然这里有D选项也是对的，那就选D了。貌似GMAT也有类似题目，就是这个要求。

7.My grandfather never learned to use a computer, (as he shops) he can accurately compute his grocery bill in his head to within a dollar.
while做conj.用时，是不跟分词的。给个例句比较明白——The lecturer supports the idea, while the student does not think so. 是这样的结构。用于两个分句的转折关系。

8.Expers agree that permanently modifying eating and exercise habits rather than merely dieting for brief periods (are the key)C (to controlling)D weight.
这句句子分析下，其实the key是指permanently modifying eating and exercise habits，即永久改变饮食和锻炼习惯这件事，而不是针对习惯这个词。所以其实是单数。

9. The exchange between the teacher and the student promotes learning far different from that which results (as)C the student listens but does not participate.
没有result as这个词组，如果表示导致的话，可以用result in 或者lead to
如果表结果则是as a result.

好长啊～可能没讲清楚，欢迎追问～
