gre填空题
My family often found others laughable,but I learned quite early to be —— while people were present,laughing only later at what was funny and mocking what to us seemed——
polite..bizarre
impatient..unfortunate
facetious..enviable
wistful..extraordinary
superficial..deplorable
我选的d 第一空应与后面的laughing only later对应,可以将答案限制在a和d,但第二个空找不到什么根据,且bizarre奇怪的 extraordinary特别的 意思上又比较接近,不知道怎么办了...当时我觉得wistful惆怅的与laugh的意思更对立,就选d了..
求高手把这个题讲明白
