以下是引用chixigua在2007-10-28 23:34:00的发言: 谁来分析一下句子结构阿,偶看不懂哎 我也认为是C,具体的原因前面的NN们已经说了 Scientists have identified an asteroid, 2000 BF19, that is about half a mile wide and that, if it were to strike Earth, could do tremendous damage to part of the planet but would probably not cause planetwide destruction.科学家们鉴定出小行星,2000BF19, 有半哩宽而且,如果撞击地球的话,将对地球有极大的破坏但可能不会引起星球范围内的毁灭. 第一个that is 和第二个that,.....,probably not cause...平行,但第二个that句里加了虚拟语气的部分 |
