为什么不选e?作者: zyh79 时间: 2002-10-18 11:18
that may be used语法上修饰elephants，逻辑上应该指待sounds，矛盾
对了，这题应该是c吧
a.逻辑错误。d.；前后为完整主谓结构。b.this 指代好像有问题 c.that在这里算不算非限制性定语从句，若是，则也错!作者: merrychord 时间: 2002-10-18 11:25
十分谢谢指点，仔细看看原来自己犯了这么一个愚蠢的错误，没看到elephants被that may be used修饰了作者: Kilroy 时间: 2002-10-18 14:13
that前有，确实很不常见，不过我见过这样一题:
A, such as B, that。。。。(好像是对的)作者: z_weining 时间: 2002-10-19 09:40
是否可以这么来解体。
a,Believed to originate 的动词发起者是elephants，不对，扔！
b,this的指代有问题，如果要指代sounds，那也要用those，不对，扔！
c,没明显语法错误
d，Originating的动词发起者是elephants，不对，扔！
e,that may be used中的动词发起者是elephants，不对，扔！
