大神们帮忙看一下啊 也有相同的疑惑 但是没找到答案
Prices at the producer level are only 1.3 percent higher now than a year ago and are going down, even though floods I the Midwest and drought in the south are hurting crops and therefore raised corn and soybean prices.
A: than a year ago and are going down, even though floods I the Midwest and drought in the south are hurting crops and therefore raised
B: than those of a year ago, and are going down, even though floods in the Midwest and drought in the south are hurting crops and therefore raising
C: than a year ago and are going down, despite floods in the Midwest and drought in the south, and are hurting crops and therefore raising
D: as those of a year ago and are going down, even though floods in the Midwest and drought in the south hurt crops and therefore raise
E: as they were a year ago and are going down, despite floods in the Midwest and drought in the south, and are hurting crops and therefore raising
the correct anwser is B, because prices can't be compared to a time period(a year ago).
But then i came cross this question(OG16 SC104):
Heating-oil prices are expected to be higher this year than last.
this original sentence is correct, as it compares this year to last(year) and it's logically parallel.
I get rather confused about those two sentences, because i think they are quite the same." Price are higher now than a year ago." and " Price will rise higher this year than last." aren't they? so why can't we just compare NOW to A YEAR AGO just like what we do in the" Heating-oil prices are expected to be higher this year than last.". Is there any reason that i can't use the same comparison structure here?
really need some pointers!thanks
