A.        both blame the other
B.        each blames the other
C.        each blame the other person
D.        both are blaming the other
E.        each blames one another

B：each在这里应该是each one的省略形式。这样the other就是指除了one以外的另一个。
E：one another: each other
   把这个意思带进去，则为：each blames each other。意思重复。

•        Although improved efficiency in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting consumption.

A.        in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting
B.        in converting harvested trees into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boost
C.        of converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, which boosts
D.        of harvested trees being converted into wood products may reduce harvest rates, it will stimulate demand, because it will increase supply and lower prices, thereby boosting
E.        when harvested trees are converted into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boost

B的错误：which修饰成分不清
C同上
D：being converted
E：when的错误。Which的错误
A中的boosting可以看作是结果伴随状语。这里不能改成boost，因为thereby是连词，不能连接动词。
BY117：Ing在句尾表示伴随结果，整个句子是原因，导致分词动作产生，无逻辑主语。

•        Researchers hypothesize that granitic soil is the ideal construction material for the desert tortoise because it is not so hard that it makes burrowing difficult or so soft that it could cause tunnels to collapse.

A.        so hard that it makes burrowing difficult or so soft that it could cause
B.        hard enough to make burrowing difficult or soft enough as to cause
C.        so hard as to make burrowing difficult or soft enough so it causes
D.        as hard as to make burrowing difficult or as soft as to cause
E.        too hard, making burrowing difficult, nor too soft, so as to cause

固定搭配：neither…nor
A中，so hard和so soft平行，共用Not.
So……that…结构，that后面接完整句子

•        After several years of rapid growth, the healthy care company became one of the largest health care providers in the metropolitan area, while it then proved unable to handle the increase in business, falling months behind in its payment to doctors and hospitals.

A.        while it then proved unable to handle the increase in business, falling months behind in its payment to
B.        while it then proved unable to handle the increase in business and fell months behind in its payment to
C.        but then it proved unable to handle the increase in business, falling months behind in its paying
D.        but then proving unable to handle the increase in business, falling months behind in paying
E.        but then proved unable to handle the increase in business, falling months behind in paying

While: 1 used to emphasize the differences between two situations or activities
      2 in spite of the fact that
此处要表示转折，while不合适
In doing sth
Paying doctors直接表达了 payment to doctors的意思，更简洁
总而言之，用最少的此传递最准确的意思！
C中，it 和its可以省略不要，完全不影响意思。相比较之下E比较简洁。
ing和名词的区别用法～！！！

刚一开始也以为ABC是缺少了was，但仔细看并不是，因为prove在这里与become一样是系动词，不需要was
（如果有was，就成了被动语态，在这里was是不可以省略，所以E就不正确了）。
该题从含义上理解，原句要表达的是转折含义，用but最恰当。
while只有对比含义，字典上如是说：used to contrast two things.(对比两件事物)而..., 然而...
所以AB是不对的。但是C又怎么解释呢？

•        In 1981 children in the United States spent an average of slightly less than two and a half hours a week doing household chores; by 1997 they had spent nearly six hours a week.

A.        chores; by 1997 they had spent nearly six hours a week
B.        chores; by 1997 that figure had grown to nearly six hours a week
C.        chores, whereas nearly six hours a week were spent in 1997
D.        chores, compared with a figure of nearly six hours a week in 1997
E.        chores, that figure growing to nearly six hours a week in 1997

D中，compared with前面是spent，后面是a figure，不对等
By: before or not later than a particular time
表示1997年以前发生的事，所以要用过去完成时

•        More than fifty years after the Second World War, a number of African American soldiers were awarded ― some of them posthumously ― with the Congressional Medal of Honor, which was the nation’s highest military award, and which was long overdue in recognition of their outstanding bravery.

A.        with the Congressional Medal of Honor, which was the nation’s highest military award, and which was long overdue in

D.        the Congressional Medal of Honor, the nation’s highest military award for long-overdue
E.        the Congressional Medal of Honor, the nation’s highest military award, in long-overdue


award sb sth./award sth to sb

recognition: public respect or thanks for sb’s work.
In recognition of sth
考点：固定搭配，插入语
be awarded 直接加名词，排除 A   B
the nation’s highest military award 是 the Congressional Medal of Honor 的同位语结构，并非定语从句修饰；long over-due 是形容词，而非副词，因此直接修饰 recognition, 排除 C
in recognition of 是固定搭配，而且 the nation’s highest military award 同位语结构用一对逗号分隔更好，排除 D
所以选 E
两个固定搭配：
1.award sb. sth.
2.in recognition of st
