单选题
Marry is
looking for
the book she lost yesterday.
【正确答案】
A
【答案解析】look for是“寻找”的意思。它是活动动词,不一定有结果,常用于进行时态。find是一个结果动词,意为“找到”,不能用于进行时态。Many people cannot find work.许多人找不到工作。try to find是“试图找到”,但这种努力不一定有结果,因此在意义上跟“look for”近似。look up是“查询”。We have to look up the meaning of this word in the dictionary.我们须查询一下词典,看看该词的意思。look at是“注视”之意。Mary is looking at Zhang San.玛丽注视着张三。
