As sources of electrical power, windmills now account for only about 2,500 megawatts nationwide, but production is almost expected to double by the end of the year, which would provide enough electricity for 1.3 million households.
A) almost expected to double by the end of the year, which would provide
B) almost expected that it will double by the end of the year, thus providing
C) expected that it will almost double by the end of the year to provide
D)expected almost to double by the end of the year and thus to provide
E) expected almost to double by the end of the year, which would thus be providing
almost逻辑上应该是指的double,而不是expect,所以A B 错;GMAT里 ,which 不能修饰前面整句话,A E错了;expected that it will中it 和前面的production是重复的,B c 错。
不过我觉得那个平行来判断thus to provide 感觉不能作为第一判据吧,一般都是连词连接两三个并列成分,如and,or,conversely,neither nor,not but,等连接主宾表状等成分,才要求并列,那个 thus是个副词,连接的不是相同成分吧
Also, the usage expected that it will almost double seems to be awkward. Although the usage of expected that is tempting BUT the usage of IT creates a confusion
Production is expected that IT double by....
OR
Production is expected to double by...
