115. Meteor showers(流星雨) and individual streaks(飞跑,滑落) of light that flash across the sky every night are generated when tiny flecks(微粒) of celestial detritus(天上的碎石), often no larger than grains(颗粒) of sand or of pebbles(小卵石), burn up speeding through the atmosphere. A. grains of sand or of pebbles, burn up speeding B. grains of sand or pebbles, burn up while speeding(flecks burn up while speeding through) C. grains of sand or pebbles, which burn up while speeding D. a grain of sand or pebble, which burns up as it speeds E. a grain of sand or a pebble, burns up when it speeds
A: grains 应该和 pebbles平行,而不是从属关系;speeding 应该修饰flecks B: correct C: when从句没谓语 D: 同上 E: burns应该用burn;it指代错(应该指代flecks)
注意: 1、判断名词平行的方式,单数对单数,复数对应复数 2、while+分词的省略,主语是主句主语
答案是选出来了,可是一看解释就迷糊了,如果B项while的主语是主句的主语,那么应该是Meteor showers(流星雨) and individual streaks,这好像逻辑意思不对阿,现象怎么能seeping through 呢?多谢nn赐教。
