以下是引用rorochen在2008-7-31 14:27:00的发言:继续讨论,我选的是c, 但答案是a,我觉得题干中说:这个plan has good chances of success是因为 1) stweet potato是当地人的主食和农业 , 2)目前其他的种植产物含beta胡萝卜素少 我觉得A的意思是现在这个种植情况,如果种spk400比起种stweet potato繁殖起来更快 而c说 : 其他的stweet potato都没有这个spk400含的胡萝卜素含量高, 我觉得和提干中的第二个 2)目前其他的种植产物含beta胡萝卜素少 差不多~~ 请高人指点一下~~~ 選項A並沒有在比較繁殖速度, 而是繁殖成功的可能性 舉個例子相親好了, 張三李四都喜歡你, 三姑六婆就覺得張三沒有MBA學位配不上你,於是就介紹MBA李四給你認識, 還推斷你們能拍拖結婚. 問支持. A選項就是你也喜歡李四 C選項就是李四是最厲害的商學院畢業的 很明顯, 就是A選項, 反駁C就是你不喜歡李四的話還管他哪裡畢業的 下面是我的筆記, 請參考一下 GWD1-Q15: 土豆引入計劃 In parts of South America, vitamin-A deficiency is a serious health problem, especially among children. In one region, agriculturists are attempting to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in beta-carotene, which the body converts into vitamin A. The plan has good chances of success, since sweet potato is a staple of the region’s diet and agriculture, and the varieties currently grown contain little beta-carotene. 要引入新品種土豆SPK, 因為bc營養多. 因為土豆是主要食物而且現在種的品種bc少營養.問計劃成功的原因 Which of the following, if true, most strongly supports the prediction that the plan will succeed? A. The growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish. 土地適合種植, 邏輯類似於GWD1-Q31 B. The flesh of SPK004 differs from that of the currently cultivated sweet potatoes in color and texture, so traditional foods would look somewhat different when prepared from SPK004. 跟現在的品種樣子看起來不一樣, 無關 C. There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is. 這是最有營養的品種<-如果SPK不適合種植的話, 計劃也不能成功. 最有營養並不是計劃成功的必要條件. D. The varieties of sweet potato currently cultivated in the region contain some important nutrients that are lacking in SPK004. 新品種缺某些其他的營養. 無關 E. There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do. 還有其他比現在的品種更有bc營養<-但無法說明新品種不會成功 |
