Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might,but climatologists have indicated all along that precipitation,torminess,and temperature extremes are likely to have the greatest impact on people.
A.Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might,
B.Discussion of greenhouse effects has usually had as its focus whether Earth would get warmer and what the extent would be,
C.Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,
D.The dscussion of greenhouse effects have usually focused on the possibility of Earth getting warmer and to what extent it might,
E..The dscussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,
OA:C
错选E
C和E最大的区别是最后那里: to what extent VS.the extent that is,
答案认为,C中whether...warmer和to what extent是平行的,还是第一次看到这样的平行。。。而且to what extent( Earth would get warmer)应该是省略这一部分吧?
E中,that没有先行词,我觉得经过OG某道新题之后发现已经不能像之前那样对待that了...不过在这里再想一下,that试图指代的是Earth would grow warmer,而这个在whether的结构之内,故无法,还是说extent的用法就是not idiomatic?
希望有人可以指正一下我的思路,谢谢!
