C The referent for the plural possessive pronoun their is unclear; it is also
unclear what the set of adjectives introduced by though is supposed to
modify. The sentence structure suggests, nonsensically, that they modify
armor plates.

单复数！！！！！未划线部有提示
A. The plural subject cuts does not agree with the singular verb is.

这个答案感觉有问题，如果B是正确的话，说明动名词和with这个结构没有矛盾，所以A也不能因为这个原因被否定掉；而且引起口腔溃疡，是这个leafty spurge的sap，所以that这个定语从句是修饰sap的，

C By making use of water instead of restrictions the subject of the that
clause, this version of the sentence necessitates the use of a wordy and
indirect passive infinitive phrase to be restricted.

A It makes no sense to say that a hypothetical increase in river level is
appreciative. The past tense of the verb resulted in this context does not as
clearly express the temporal relationships between the announcement and
the other events as would the past perfect had resulted.

C D a decline is strictly speaking to a number, not to
an estimate.

of them 关键信息竟然没看到！！！

ABE THEIR应改成 IT C each of which 是非限制定从 要完整

D. This variant seems to suggest, illogically, that Cavendish devised an instrument
from several objects plus employment; using employed instead of employment of
would be one way of correctly pairing his two actions.

C. Connecting the three parts of the sentence with two occurrences of and is
awkward; the first two parts are best connected by and, but the final portion
expressing what Cavendish achieved would be better expressed, for example, as a
new sentence beginning, In 1797–1798, he employed.

这题不会直接影响所以用从句
集合名词用单数

DE比较对象不平等 一以来很疑惑的这种问题可以用时态来排除

这里只说了consider和consider to be的区别，没说consider as 啊？

they may not think statements are true
that they may not think 是插入语

D As in (A) and (B), the beginning of this sentence is inconsistent with the
rest of it. The opening phrase claims to describe preparations for a
prediction, whereas the latter part of the sentence indicates that the
preparations are for a predicted earthquake.

A In this version of the sentence, the opening phrase illogically claims that
the California Office is preparing for a prediction, but later in the sentence it
becomes clear that the preparations are targeted to the aftermath of a
possible earthquake, not its prediction.

living 的主语每次都忘了这一点

whose 是属性 with是状语！！！

C continue to do 语意上已经包括到现在为止已经的概念

disinclination 不情愿 考察的是动词和动名词的区别别被C给迷惑了
