6. The banana that contains high level of potassium and other important minerals are considered to be one of nature’s healthiest fruits.
        A. The banana that contains high level of potassium and other important minerals are considered to be
        B. The banana, which contains high levels of potassium and other important minerals, is considered
        C. The banana, which contain high levels of potassium and other important minerals, is considered to be
        D. Bananas which contain high levels of potassium and other important minerals are considered
        E. The banana, which contains high levels of potassium and other important minerals, is considered to be

选项解析：
This sentence discusses characteristics of“the banana,” a singular subject. Thus, the plural verb “are” is incorrect.Additionally, the phrase “considered to be” is unidiomatic. In standard writtenEnglish, “considered” is accompanied by neither a preposition nor a verb.Finally, the relative pronoun “that” makes it seem that a particular banana,rather than bananas in general, contains high levels of potassium.
(A) This choice is incorrect as it repeatsthe original sentence.
(B)CORRECT. This choice correctly uses the singularverb “is” with the singular subject “banana,” and correctly uses “considered”without an accompanying preposition or verb. Additionally, the relative pronoun“which” properly introduces a non-restrictive clause that indicates allbananas, rather than one specific banana, contain high levels of potassium.
(C) The plural verb “contain” isincorrectly paired with the singular subject “banana.” Additionally,“considered to be” is unidiomatic.
(D) The relative pronoun “which” isincorrectly used to introduce a restrictive clause. Also, the sentence seems toindicate that certain bananas, rather than all bananas, contain high levels ofpotassium.
(E) This choice incorrectly uses theunidiomatic “considered to be.”

题目点评：
本题涉及考点：主谓一致，修饰，固定搭配

首先，banana是单数主语，因此谓语动词用单数，排除A，C，D。

剩下B和E，不同在于consider的用法。Consider A B，把A认作是B。这是标准书面语的固定搭配，中间不加as和to be，其中B为名词或形容词。在日常用语和非正式书面语中，to be或者as出现也是正确的，但是在标准书面语中，这就属于累赘（redundant）。因此排除E。

本题中，A,D跟其他三个选项不同的地方还在于使用了限定性定语从句。非限定性定语从句与限定性定语从句的区别：非限定性定语从句非限定性定语从句在形式上就与主句很松散，它与主句之间有一个逗号隔开（注意了噢，并不是通过引导词是that 还是which来判断，而是通过是否有逗号来判断）；它对其先行词没有限定、修饰的作用，只起补充、说明的作用。有时也用它来对全句进行补充、说明。即使将其去掉，也不会影响句子意思。限定性定语从句限定性定语从句与主句的关系很紧奏，对其先行词起限定、修饰的作用。如果将其去掉，会影响句子意思的完整性；有时甚至于引起费解、误解。The banana that……就意味着是特指某一类香蕉，是不合理的。实际上句意是泛指香蕉这种水果是健康食品，从句只是起到对“香蕉”的一个解释作用。

感谢若雪对限定性引导词进行了OG的查证：
Some writers follow the convention thatwhich can only be used for nonrestrictive clauses, but insistence on this ruleis controversial
补充：需要注意的是，并不是出现consider sth to be/as就是错的。Consider A B是最优，但如果不存在最优形式的时候，considerto be就是相对较优的选择。比如以下这道GWD题目，consider to be就不属于考察对象

In California, a lack of genetic variationin the Argentine ant has allowed the species to spread widely; due to theirbeing so genetically similar to one another, the ants consider all theirfellows to be a close relative and thus do not engage in the kind of fierceintercolony struggles that limits the spread of this species in its nativeArgentina.
A.due to their being so genetically similarto one another, the ants consider all their fellows to be a close relative andthus do not engage in the kind of fierce intercolony struggles that limits.
B.Due to its being so genetically similarthe ant considers all its fellows to be a close relative and thus does notengage in the kind of fierce intercolnny struggles that limit.
C.Because it is so genetically similar, theant considers all its fellows to be close relatives and thus does not engage inthe kind of fierce intercolony struggles that limits.
D.Because they are so genetically similarto one another, the ants consider all their fellows to be close relatives andthus do not engage in the kind of fierce intercolony struggles that limit.
E.Because of being so genetically similarto one another, the ants consider all their fellows to be a close relative andthus do not engage in the kind of fierce intercolony struggles that limits.

思维点评：
1. “D里面which用的也不对，加逗号或者改成that”——fdrandom
改成that并不对哦，这里不能使用限定性定语从句，理由见题目点评部分。

2. “但是BE选项都不好，因为这里用限制性定语从句比非限制性定语从句要好。该香蕉是什么？最好有一个说明”——DoGMATRight
并不是说非限定性从句就不能对主语作出说明，恰恰相反，它起的就是这个作用，可以仔细体会一下这两种从句的区别。

idiom： consider A B 不用加to be 或者 as，因此排除ACE
纠结B和D，差别就在单数和复数表示上，看到划线后的one，觉得应该是the banana吧。又觉得，D中which前没有逗号，是限制性定于从句，句意变成了”那些含有....的香蕉"，改变了句意。
因此，选B吧。

nhelpn

B
划线部分后边跟“one of”，提示前边是单数，用is。 contains应和be动词的数一致。
consider后边的to be 经常省略。
根据句意，是说香蕉是健康食品，而不是说“某种香蕉”是健康食品，故限定性定语从句D不合适

fdrandom

选B么？
首先consider A B的固定搭配，排除A、C、E，然后one of nature’s healthiest fruits前面应该用The banana，排除D，D里面which用的也不对，加逗号或者改成that

6. The banana that contains high level of potassium and other important minerals are considered to be one of nature’s healthiest fruits.
A    The banana that contains high level of potassium and other important minerals are considered to be
B   The banana, which contains high levels of potassium and other important minerals, is considered
C   The banana, which contain high levels of potassium and other important minerals, is considered to be D    Bananas which contain high levels of potassium and other important minerals are considered
E  The banana, which contains high levels of potassium and other important minerals, is considered to be

Potassium 钾
本句意思是说，香蕉 （是有高含量的钾和其他重要的矿物）被认为是最好的自然健康水果之一。

考点，限制性与非限制性定语从句，谓语单复数搭配，习惯用法。

A consider A B,不用加to be。

B 正确。

C consider A B,不用加to be; the banana 做主语，定语从句中的动词contain应该用谓语单数。

D bananas which， 是限制性定语从句，首先，限制性定语从句不能用which引导，which引导非限制性定语从句，限制性定语从句修饰物，应该用that。第二，从意思上来讲，限制性定语从句特指香蕉中高钾含量和高矿物质含量的那种香蕉，而不是整个所有的香蕉。

E consider A B,不用加to be。

B
主谓一致
固定搭配，consider后面不需要to be或者 as， consider A B,  A is considered B
延伸讨论：
非限定性定语从句修饰表示共性
如果改成限定性定语从句，则意思有点怪，感觉是在说
只有那些富含potassium和其他重要矿物质的香蕉才是自然界最健康的水果之一。

嘻嘻。速度做掉然后去做专业课的作业^_^ 每日SC都成为习惯啦~


B


香蕉【定语】被认为是最健康的水果之一
主谓一致 排除A C
one of the..fruits所以主语肯定是单数，继续排除D
剩下DE consider用法
consider sth (to be)sth 也有consider AB。to be 在GMAT中倾向省略
果断B~

讨论一下：
刚发完看到LS有纠结限定性和非限定性。我记得OG里面明确说了,限定性和非限定性本身就很controversial，+which也未必是非限定性的吧~刚回到OG找了下OG原话：In (A) and (C), which introduces a restrictive clause. Some writers follow the convention that which can only be used for nonrestrictive clauses, but insistence on this rule is controversial, and both (A) and (C) can be rejected on other grounds.


题目：
Carnivorous mammals can endure what would
otherwise be lethal levels of body heat because they have a heat-exchange network which kept the brain from getting too hot.
(A) which kept
(B) that keeps
(C) which has kept
(D) that has been keeping
(E) having kept

题目：
Carnivorous mammals can endure what would

(A) which kept
(B) that keeps
(C) which has kept
(D) that has been keeping
(E) having kept

感觉象network，style，这一类比较抽象的词一般用限定性的定语从句修饰来收窄概念
而另外一些具体的名词，用限定性定语从句修饰还是强调总体里面那一类的东西，用非限定性定语从句则是表达这些具体物品的共性。
OG里面的解释我理解意思是说which是否只可以引导非限定性定语从句存在争议。

谢谢helio ^_^ PS：我刚刚醒悟过来您是传说中的腾飞咆哮帝诶~腾飞就在我家旁边。。咳咳。。
哎呀呀，刷OG的时候没看明白扫一眼就过去了....导致后来看到限定性非限定性就先找别的错误orz
那是不是还是可以理解为,+which 就是非限定性嘞..？



【更新一下~】发现自己在第一遍刷OG的时候查过限定性和非限定性从句~
贴上来~


限定性从句与被修饰对象有紧密的关系，在句子中充当很重要的成分，不可以省略，如果省去就会造成句子意思不完整
而非限定性定语从句，是属于对被修饰对象的进一步说明，去掉以后不影响句子意思。
比如说这句话吧 Many house builders offer rent-to-buy programs that enable a family with insufficient savings for a conventional down payment to move into new housing and to apply
that从句修饰programs，是句子里不可缺少的一部分，少了这一部分句子意思严重不完整
而lz再换上which试试看，把which后面的内容去掉后，这句话还有什么啊？就完全表达不出原句的意思啊，很重要的内容都给省去了。


限定性从句与被修饰对象有紧密的关系，而非限定性就很一般了which多数不能作引限制性定语從句
