简介：首先要告诉大家．这里写的不是什么Reason的教材．而作为Reason也不可能出现可能完整的教材的。千变万化的自我组合性能正是Reason吸引人的地方。JT在这里抛砖玉，略略带领大家感受一下Reason到底好玩在什么时候地方。说不定Mac上从此又多了帮Reason迷呢！

简介：假如你碰到这样的选择题：Ｔｈｅｒｅａｓｏｎｈｅｉｓ　ｌａｔｅ　ｉｓｉｔｒａｉｎｅｄ．Ａ．ｔｈａｔＢ．ｂｅｃａｕｓｅ正确答案是哪一个呢？也许这样的题你见得太多了，会说选Ａ。是的，出题者正是这样想的；许许多多的试题也是这样设计的。当然，ｔｈｅｒｅａｓｏｎｉｓ后的表语从句用连词ｔｈａｔ引导是没有问题的，大量的例句证明了这一点。但是，一些参考书和各种考试指导书一律把这一结构中用ｂｅｃａｕｓｅ判作错误。有的解释说“ｂｅｃａｕｓｅ引起的表语从句只能用在ｉｔ（ｔｈｉｓ，ｔｈａｔ）ｉｓｂｅｃａｕｓｅ的结构里”，“ｔｈｅｒｅａｓｏｎ…ｔｈａｔ这种结构常常会误用成ｔｈｅｒｅａｓｏｎ．．．ｂｅｃａｕｓｅ”。有的把用ｂｅｃａｕｓｅ当成典型错误例析，说“名词ｒｅａｓｏｎ不能与表示原因的ｂｅｃａｕｓｅ同用在一个句子里，以免犯重复的错误，例如不能说：Ｔｈｅｒｅａｓｏｎｗｈｙｈｅｄｉｄｔｈｅｊｏｂｐｏｏｒｌｙｉｓｂｅｃａｕｓｅｈｅｌａｃｋｅｄｅｎｔｈｕｓｉａｓｍ．这里应把ｂｅｃａｕｓｅ改为ｔｈａｔ”。有的在英文正误句举例说“中文是说‘……的原因是因为……’，但英语绝对不能说ｔｈｅｒｅａｓｏ...
