GWD-2-4 一道有争议的题 请教

大胖

On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow, as seen in the rings visible in the cross sections of their trunks.

 

1. On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow
2. On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth
3. On Earth, the rate at which trees grow is believed to be among the surest indications of sunspot cycles
4. Among the surest indications on Earth of sunspot cycles, believed to be the tree growth rate
5. Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow

答案给的是C      ， 也有人说prep出现过这题上选E

 

此题考的是倒装，主语是the rate at which trees grow，谓语是are,由主谓一致原则可知A，B都错了，D无谓语，也不能选。剩下的C和E选项中，

1、选C 的认为：E会造成语义不清，sunspot cycles是修饰earth还是indications, 表达不够清楚，所以答案选C。

 

2、选E的认为：C选项as seen in the rings visible in the cross sections of their trunks  错误的修饰了sunspot cycles。  

 

 到底应该选哪个呢？

选E prep答案为准

on earth修饰indications--------indications of sunspots cycles

而在C里面成了 on earth修饰整句话

修饰语的位置要合理

E中as seen in the rings visible in the cross sections of their trunks修饰的是rate才对。
