简单的说一下 1.它的结构应该不是 are difficult to please, frugal, and reluctant 因为你要注意后面还有个to bargain。 所以它这句应该是 are difficult to please,are frugal, and reluctant to bargain. please是动词,pleased, pleasing才是形容词。所以合并后 C是正确的。 2. immune to 是固定用法意思是不受影响。再来结合句子意思,是说南极似乎以前都不受全球变暖影响,1957年后就不是这样了。所以E的选项简洁明了。 -- by 会员 kiwifoodtown (2012/11/15 10:02:22)
所以它这句应该是 are difficult to please,are frugal, and reluctant to bargain. 这里是不是difficult to please, frugal, reluctant共用前面的are呀?然后这三个平行? |
