这里on Earth位置的改变似乎没事？。。。
这里可能还会涉及到一个就进修饰的问题。但也有一个反例。prepq 138
According to scientists at the University of Alaska, while the surface temperature of the globe has risen over the last century by about one degree Fahrenheit, the surface temperature in Alaska, Siberia, and northwestern Canada has increased in the previous thirty years by about five degrees.
(A) the surface temperature in Alaska, Siberia, and northwestern Canada has increased in the previous thirty years by about five degrees
(B) the surface temperature in Alaska, Siberia, and northwestern Canada has increased over the last thirty years by about five degrees
(C) there was an increase in the last thirty years by about five degrees in Alaska, Siberia, and northwestern Canada
(D) it had increased in Alaska, Siberia, and northwestern Canada by about five degrees over the previous thirty years
(E) it has increased in Alaska, Siberia, and northwestern Canada over the previous thirty years by about five degrees
选B
这里只是因为对称才说over the last thirty years by about five degrees（和and前对称）。还是说本身over the last thirty years就比by about five degrees修饰关系更紧密呢？可是我怎么觉得明明是后者比前者紧密？
