[whereas]前后要有明显的转折
Only if 别人做某事,only if 是连词,不可和其他连词重复使用,排除AB;
解题关键在bottom line上,在经济学中,bottom line专指净收益,意思等同于net income。根据原文reluctant to abandon this strategy despite its effect on the bottom line看出此处的effect应该是负面影响,也就是收益损失。知道这个意思后看选项哪个会对净收益产生负面影响。
read of 强调通过阅读了解熟悉
as as ABC就去掉了
1. Joe studies more at night that he does during the day. (The sentence compares Joe to himself.)
AD之间选,or可以平行 being 。。。 repressing 一样用与them
20 percent看后面的 所以hours 用 many
be aiming to do / be aimed at doing (*be aimed to do* is wrong)
that 这个从句修饰了molecules, so use "play" rather than "plays"
from Manhattan:
B: try and recover
X can be as important as Y. X and Y can be equally important. But X cannot be equally important as Y
平行,A:an understanding of xxx is as xx as grasping 错误
B选项:复数名词 20-foot-long implements和单数名词a bull rake在单复数上不匹配,由于两者上known as的关系,所以应单复数一致。
A选项:which引导的定语从句,Greek alphabet为先行词;其中itself作为Greek alphabet同位语;时态用过去完成时,与适应之前的字母相比,早一点;
我也认为解释有问题,B和D的的主语不应该是Roman alphabet吗????
itself themselves不能做主语所以C错了
B是要看主语 发出的动作,这些都不是主动发出的所以不选B
E选项:rob和make是alter的两个并列的后果,两个并列是成分用and连接时,and身前不能有逗号。
