但是whose sum of distances from two fixed points in constant.我就搞不懂了,这里
whose sum of distances对么?还有我从太傻上下载的真题里的 c 选项怎么是whose sum of whose,然后她给出的选项是a, 然后我从寄托上下载的托福语法笔记上面印的c答案也是whose sum of whose,他给出的正确答案也是a,但是我买的寄托文丛(蓝色的四本),上面印的答案是我现在打印的whose sum of ,正确答案却选的是c,所以我现在有些糊涂,究竟真正的托福考试真题这道题的c选项是什么,正确答案究竟是什么?作者: wadewizard 时间: 2006-7-30 12:16:21 标题: 哪位大虾解答一下呀,谢谢了!
