带方框的27是对的

答案是A

扯淡

句意

老师，这个题目如何分析？能否讲解一下？

mark, D&E
D if the adjective is "many", "few", "much", or "little", then you cannot write "NOUN as adj. as..." Instead, you must write as many NOUNs as、as few NOUNs as、as much NOUN as、 as little NOUN as…
E的问题是同D

毕老师，C和D的对错，判断的依据是什么呢？我选择了C

虚拟条件句的四种形式：
But for N, S + should/would/cold/might + V / (have Vpp.) 若不是N, S应该….
= If it were not / (had not been) for N
= Were it not for N / (Had it not been for N)
= Without N（介词只有without可表虚拟语气）
虚拟语气的时态：
时间 从句谓语形式 主句谓语形式
将来 动词过去式(be用were)
should + 动词原形
were to + 动词原形 would / should / might / could + 动词原形
现在 动词过去式(be 用 were) would / should / might / could + 动词原形
过去 had +动词过去分词 would / should / might / could have + 动词过去分词

RON： AB的真正错误是if it were not和instead之间的重复

A的错误在于crossing是个伴随状语修饰Gypsy，但实际上句意是说科学家通过crossing...的方式来尝试发展balabala...此处我觉得attempt at并没有什么错误

E-The rate at which trees grow, as seen in the rings visible in the cross sections of their trunks,is believed to be among the surest indications of sunspot cycles.

为什么不选C:
as seen的修饰对象。as seen说的是“正如（我们在）树桩上的年轮所看到的那样”。
从语义上应修饰树的成长，把句子还原trees grow at the rate as seen in the rings visible in the cross sections of their trunks. 树木增长的速度，从树桩上年轮的圈上可见一斑。
C选项，使得as seen的修饰对象变成了sunspot cycles，语义完全错误了。

In Hungary, many of them in middle management and light industry(同位语),an overwhelming proportion of women work as in much of Eastern Europe.

administering tribal lands 而不是change

(1) incorrect idiom: 'promise of keeping' is wrong. the correct form is 'promise to keep'.
(2) change in meaning: the correct meaning is what appears in the original sentence, namely, that the failure to honor promises WAS the deceptive business practice. choice e, with its use of 'because', implies that the failure to keep promises LED TO (other) deceptive business practices. remember that you have to interpret words like 'because' very, very literally.

D E 的BUT为连词但没有足够的平行结构支撑
A的having逻辑主语错误
C 中的 at the same time作为时间状语修饰整个句子，那which可能就是修饰time的。

Some historians contend that conditions in the United States during the Second World War gave rise to a dynamic wartime alliance between trade unions and the African American community, an alliance that advanced the cause of civil rights
某些历史学家认为二战后美国的这种环境促使贸易公会与非裔美国人群体的动态战时联盟，这种联盟使得市民权开始产生。
have portrayed organized labor as defending all along the relatively privileged position of White workers relative to African American workers.
学者则认为有组织的劳动者是为了维护相对黑种工人的白种工人的高地位。

虽然知道是内涵和外延的考点，但是在这个题目上不知道如何运用，从另外一个角度，对C的错误试着理解如下：
1，如果用IN doing，则可以理解为，在做...的时候，二氧化硫削弱了他的能力，至于哪个方面的能力，并不明确，因为in 的结构不如to do的结构能够表达。可以理解为实意的缺失。
2，如果要用capable表达某个方面的能力，应该用capablity of.
3, 而B的错误，用because of 则比较明显了，考点应该是核心词。
请指正。
