若有打错,Please见谅.

第一题
错误 C （改为 thoroughly）
1、本句结构
原因状语：Because Ms.M,the new chemistry teacher,presented the subject so thoroughly,—— 由于新化学教师 M 女士是那样精确地地提出这个课题
主句：concepts now seemed simple to students 一些概念现在对学生来说看起来简单了.
定语从句：that had been difficult to understand 曾经是难于理解的（一些概念）
2.选项分析,
A.Because —— 引导原因状语从句Ms.M,presented the subject,没有错
B.presented —— 是原因状语从句中的谓语动词,时态正确,没有错误
C.so thorough —— 应该是谓语动词 presented 的程度状语,但是thorough 是形容词,应该改为副词 thoroughly
D.had been difficult —— 是主句中主语concepts 的定语从句that had been difficult to understand.中的谓语部分（系表结构）,没错.
第二题 ）
错误 D （应该改为having revised
1、本句结构
原因状语：Determined to make a name for herself as a writer of short stories,——因为决心作为短篇小说作家使自己成名.
句子主干：He never submits anything to an editor until revising it several times.直到修改了几次后他才向编辑提交了作品
2、选项分析
A.Determined —— 由 when he is determined to 变化而来的分词短语状语,没错.
B.for herself——是惯用短语to make a name for … (使某人成名) ,没错.
C.as a writer —— 介词 as 表示“作为”,没错.
D.revising —— 因为修改文章发生在提交之前,因此需要用动名词的完成时态,应该改为 until having revised
第三题
错误：A（把 of 改为 for）
1、本句结构
主干句：The Environmental Protection Agency has named six winners for their Water Efficiency Leader Award,——环境保护局已经提名六个优胜者为他们的水效率领导奖
Award 的非限制性定语created to encourage innovation in developing products and practices that use water efficiently —— 这种奖励是位鼓励在发展生产和用于水效率实践中的创新而设立的
2、选项分析
A.of their ——介词用法错误,习惯用语是 name sb.for,意思是“提名某人为…”
B...to encourage —— 不定式作 created 的目的状语,即“为鼓励而设立”,没错.
C.innovation in —— innovation 是 encourage 的宾语,介词 in 和后面的developing products and practices 构成了 innovation 的后置定语.没错
D.use—— that use water efficiently 是复数名词 practices 的定语从句,没错.
