主谓不一致。。

这个解释真好

In addition to整个词组相当于一个介词,所以to的后面要接宾语.例如:
In addition to native plants,this garden contains numerous trees and flowers from overseas.

thanks

1里 X+k=2
2里2x+k+4
解出x=2 K=0

that 不要修饰人！

细节题：
题目中关键词“ modernization of the telephone exchange”只在文章的第一段和最后一段2处出现，坦白的说，考试不能ctrl+F快速查找还挺困扰的。。这么长一篇好一顿找：（
第一处：文章第一句话，重点是说Jon Clark's study of the effect，主要不是说modernization of the telephone exchange，没啥关系；
第二处：At the empirical level Clark shows how a change at the telephone exchange ...switching systems altered work tasks, skills, training opportunities, administration, and organization of workers. 选项与之有关的只有C

因果推理，方案已经被评估了。

好像有种搭配是gear toward，gear to貌似还没有得到验证，如果有人看到official used version, plz correct me,thx

LZ,作者比较的同时还要表达一个时间的不一样，句子意思是homas Eakins's powerful style and his choices of subject曾经是disturbing to his own time，而同样的现在正在compelling for ours，能表达这种时间上的不一样的只有B选项，E选项没有表达不同时间，所以不对。-------摘自逐梦网

前面一句话和后面一句话比较 Owning a house is a goal of many young people as it was of earlier generations. 楼上说的对，这里面关键是要体现出前后时态不一致，一个是过去的影响一个是现在的，如果你后面像E一样就默认了时态和前面是一致的-----摘自逐梦网

错选B。
还是觉得是因果。。。

E为什么不对？

天啊没注意little of要接不可数名词！

主要考察平行：
A.up to [150 miles per hour in speed] and [200 feet high]（up to and high are redundant）
B.[up to 150 miles per hour in speed] and [heights of up to 200 feet]
C. speeds of up to [150 miles per hour] and [200 feet high]
D.[speeds of up to 150 miles per hour] and [heights of up to 200 feet]
E.[speeds of up to 150 miles per hour] and [as high as 200 feet]

为什么D不对？本来首都人民就有了转换器 排放的就不多，再减少也减少不了多少？

读题失败：是k+5后的十位数为4.

but 和 and 之间的with 不是一个完整句子

[u][sing]~ (for sb/sth)偏爱；爱好；喜爱a greater interest in or desire for sb/sth than sb/sth else
