Recently documented examples of neurogenesis, the production of new brain cells, include the

brain growing in mice when placed in a stimulating environment or neurons increasing in canaries

that learn new songs.

(A) the brain growing in mice when placed in a stimulating environment or neurons increasing in

canaries that

(B) mice whose brains grow when they are placed in a stimulating environment or canaries whose

neurons increase when they

that increase when they

(D) the brain growth in mice when placed in a stimulating environment or the increase in canaries'

neurons when they

(E) brain growth in mice that are placed in a stimulating environment or an increase in neurons in

canaries that

考点:简洁有效（Rhetorical Construction）逻辑表达（Logical Predication）

1) 当动词有名词形式时,就不要使用the +动词ing形式来表达其名词形式

2) 介词+动词分词在句首,逻辑主语等于主句的主语;在句尾,逻辑主语可能等于主句的主语,也可能等

于所修饰的动词的逻辑主语

(A) the brain…无法与the production of…平行；growing使用错误,应该用grow的名词形式growth来替

换,increasing应该用increase替换;介词结构when placed无论是修饰主句的主语还是所修饰动词

(include)的逻辑主语,该结构都是修饰的documented examples,而从逻辑意思上看,when placed应该

修饰mice,因此when placed修饰对象错误.

(B) 改变句子意思,从未划线部分看,examples包括的对象应该能够表现neurogenesis,同位语对该词

进行了解释 the production of new brain cells,而选项B的例子包括的是mice和canaries,这两个动物

不是the production of new brain cells的例子,而应该用brain growth in mice和an increase in neurons

in canaries作为the production of new brain cells的例子;指代错误,选项中的they分别就近指代brains

和neurons,导致了逻辑意思错误.

(D) when placed修饰documented examples,导致逻辑意思错误,代词they就近指代neurons,导致逻辑

意思错误

(E) 正确, brain growth in mice和an increase in neurons in canaries很好的作为了the production of

new brain cells的例子;限定性定语从句that…分别修饰mice和canaries,修饰对象正确.

Scientists at the Los Alamos National Laboratory have succeeded for the first time in mining heat

from the Earth's interior and producing energy on a commercial scale, enough for efficient

generation of electricity and heating factories and homes.

(A) and producing energy on a commercial scale, enough for efficient generation of electricity and

heating

(B) and producing enough energy on a commercial scale for electricity to be generated efficiently

and to heat

heat

(D) to produce energy on a commercial scale, enough for generating electricity efficiently and for

heating

(E) to produce enough energy on a commercial scale for efficient generation of electricity and heat

考点: 平行对称（Parallelism）简洁有效（Rhetorical Construction）

1)表示目的时,to do结构比for结构更有效

2)有动词形式的时候尽量用动词形式,不要用动词的抽象名词形式

(A) have succeeded…and producing…前者是动词结构,后者是动名词结构不平行; enough for

efficient generation…and heating前者是名词结构后者是动名词结构不平行;generation属于动词的抽

象名词不如动名词generating好

(B) and producing错误同A选项;… scale for electricity…and to heat, for结构和to do结构破坏了平行,

要么都用for结构,要么都用to do结构

坏了平行

(D) 正确, 使用to produce表达目的;enough for generating…and for heating结构平行,且使用动名词

形式,比动词的抽象名词形式更佳有效的表达的动作的意味.

(E) heat跟produce平行,导致逻辑意思错误;generation不如generating好

求解，动词的名词形式和动名词到底哪个优先？这两题是不是矛盾了？
