请大家拯救我这个SC渣~ 想请教牛牛们 关于对比的省略~

ellen26wang

渣渣我一直对比较的省略无可奈何！而后今天在看OG的时候简直就疯了！
就想问问牛牛们 为何 104题 不用last year's 而 90题 却要补出those of a year ago?
那如果照OG上面对104题给出的解释，说 this year 和 last 才能比，我想知道那为什么 90题里的 now 和 a year ago 不能比...

（在此小女子先谢谢各位大牛牛们了~）


OG16-104     
                  Heating-oil prices are expected to be higher this year than last because refiner are paying
                  about $5 a barrel more for crude oil than they were last year.（选 A）


                 (A) Heating-oil prices are expected to be higher this year than last because refiners are paying
                       about $5 a barrel more for crude oil than they were
                 (B) Heating-oil prices are expected to rise higher this year over last because refiners pay
                      about $5 a barrel for crude oil more than they did
                 (C) Expectations are for heating-oil prices to be higher this year than last year’s because refiners are paying
                      about $5 a barrel for crude oil more than they did
                 (D) It is the expectation that heating-oil prices will be higher for this year over last because refiners are paying
                      about $5 a barrel more for crude oil now than what they were
                 (E) It is expected that heating-oil prices will rise higher this year than last year’s because refiners pay
                      about $5 a barrel for crude oil more than they did

OG16-90
                Prices at the producer level are only 1.3 percent higher now than a year ago
                and are going down, even though floods in the Midwest and drought in the
                South are hurting crops and therefore raised corn and soybean prices. （选 B）
               
                (A) than a year ago and are going down, even though floods in the Midwest
                      and drought in the South are hurting crops and therefore raised

                     Midwest and drought in the South are hurting crops and therefore raising

难道是因为  a year ago 是做状语的? 但 now只是副词？

Both of the comparision are correct -
Q104:  Prices are higher this year than last year.
Q90:   Prices are higher now than those of a year ago.

For instance, all of the following are correct -

I eat more than Tom .
I eat more than Tom does.
I eat more in the restaurants than at home.

The reasons that pick up choice A as correct one for Q104 are:
- "higher....over" is not right, so eliminate B, D.
- Chocie C: 1) the comparision is "expectations"  vs. "last year's".  2) "last year's" is not correct.
- Choice E: 1) "last year's" is not correct. 2) "Refiners pay $5 a barrel for crude oil more than they did." is not correct. It should be " Refiners pay $5 a barrel more for crude oil than they did".


For Q90 :
- "higher.... as" eliminate D and E;
-Choice A: The meaning of the sentence talks about the present situation : Prices now are only slightly higher than a year ago; flodds and drought are hurting crops; Consequently, the prices are raising.  So, the past tense " raised" is not correct.

- Choice C means " Prices are only slightly higher now than a year ago and (prices) are hurting crops and therefore raising corn prices."  You can find the purple part is totally wrong.

Q104 为什么 prices are high this year than those of last year/ last year's 就不对呢？ 不是应该和90一样吗？
