21、认识你是十分高兴的事。She has few pleasures left in life.她生活中已没有什么乐趣了。拓展：抽象名词的具体化是高考的常考点之一，现总结如下：(1)表示具有某种特性、状态、特点、情感、情绪的人或事，且表示变化了的词义时，这类抽象名词由于已具体化，故可变为可数名词。如：a pleasure 乐事 a success 成功的人或事a surprise 奇异的事 a failure 失败的人或事a pity 可惜的事 a must 必要的事a worry 令人担忧的事 a wonder 奇迹a great help 有帮助的人或事 a youth 年轻人a danger

24、g是现在完成进行时。完成进行时是现在完成时的强调形式，表示动作从过去某一时间开始，一直延续到现在，可能还要继续下去，通常与表示一段时间的状语连用，如：for hours, since this morning等，其构成是“have/hasbeen现在分词”。I have been looking for my lost book for three days, but I still havent found it.我已经花了三天的时间找我丢失的书，但还没有找到。【注意】现在完成进行时与现在完成时的区别：二者都可以表示动作的延续，区别在于：前者更强调动作的延续性，可以说是后者的强调形式。We
