Scientists calculated that the asteroid, traveling at 46,000 miles an
hour, is on an elliptical path that orbits the Sun once a year and regularly brings it
back toward Earth.
选项
A、hour, is on an elliptical path that orbits the Sun once a year and regularly brings it
B、hour, is orbiting the Sun once a year on an elliptical path that regularly brings it
C、hour, once a year orbits the Sun, regularly bringing it on an elliptical path
D、hour and orbiting the Sun once a year on an elliptical path, regularly bringing it
E、hour, orbits the Sun on an elliptical path once a year and that regularly brings it
答案
B
解析
A选项中,第一个that从句,即that orbits the sun有问题,因为把先行词a path代入从句,句意就变为:椭圆形的路径绕太阳运行,而这从逻辑上显然说不通;而应是:小行星以椭圆形的轨道绕着太阳转,排除A。C中:once a year这个时间状语放在主语与谓语之间是不恰当的,同时bringing短语部分无论作伴随状语或伴随结果同样是不可理解的,排除C。D中:在calculated的宾语从句中,主语之后是三个并列的现在分词短语:travelling,orbiting,bringing,而没有谓语,该从句结构不完整。E中:划线部分末的that定语从句之前有and,却找不到与之平行的成分(与句首that引导的宾语从句并列是不可能的)。B正确:is orbiting表明此动作一直在持续,path才是bring的真正动作执行者。
