我做完形填空题, 是这样: Other tests have shown that laughter ( ) to be able to reduce the effect of pain on the body. A.appears B.seems C.Both A and B 答案是什麽? appear to do和seem to do可以互换吗?有什麽区别?
选C.都可以 appear to do和seem to do可以互换。 英汉词典对seem 的解释之一是: seem: appear to be somthing. 这也是词典的解释: ★seem 和 appear 在应用上常无差别,但前者似可导致某种结论,后者仅仅显示某一客观现象:He seems to be sick, for he appears pale. -er
