标题: prep1-102(与gwd那道选项设置不同）

In parts of South America, vitamin-A deficiency is a serious health problem, especially among children.  In one region, agriculturists hope to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in betacarotene, 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.

Which of the following, if true, most strongly supports the prediction that the plan will succeed?

A. There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do.

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.

C. For successful cultivation of SPK004, a soil significantly richer in nitrogen is needed than is needed for the varieties of sweet potato currently cultivated in the region.

D. There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is.

E. The currently cultivated varieties of sweet potato contain no important nutrients that SPK004 lacks.

答案选的是E

我选D

gwd的题目无E这个选项

大家能帮我解释下D为什么不可以嘛？？

谢谢大家啦

D has nothing to do with successful plan.

GWD-1-Q15跟这个题干一样，选项不同。出题的家伙好狡猾，把选项改一改就把我们弄晕了。不过LZ问的D选项跟这个题里的C是一样的，都是错的。

因为：其它东西里含的beta-carotene 比SPK004多不多跟题目无关，因为只要SPK004比现在种的sweet potato里含的beta-carotene 多就可以了。所以，这种错误类型叫做无关比较

Which of the following, if true, most strongly supports the prediction that the plan will succeed?

  1. The growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish.

  2. 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.

  3. There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is.

  4. The varieties of sweet potato currently cultivated in the region contain some important nutrients that are lacking in SPK004.

  5. There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do.

answer : A.

E 现有的土豆不含有SPK004缺少的营养物质

怎么看怎么象无关项。。

d:说明了没有有更好的添土豆，这并不能说明现在的plan不能成功，只是不一定是最好的plan

e：说明现在这个SPK004有营养上的缺陷

选E

SPK004有缺陷 为什么还能SUPPORT种SPK004会成功提高营养???

作者: stellachan    时间: 2009-6-13 18:13

有点明白了。。

这个E选项是说 这个品种的土豆没有的营养物质 其他土豆也没有  还比其他土豆多种物质帮忙转化维生素A   所以种这个土豆会提高国民身体素质 是这意思不????

SPK004 有部分营养缺陷不要紧啊,其他SWEET Potato没有营养缺陷,可以混在一起吃啊.

又没说吃SPK004的人就不吃其他Sweet Potato.

请大牛指教!!

好像是这样的, 反正大家都不含其他重要的营养物质, 而K 还多一个别的... 那就没选择了.. 种K吧....

E明白了，可是对于D我还是有疑问。原文最后一句话，大家看，the plan has good chances of success,为什么有可能成功呢？后面马上那个给出了原因，since sweet potato is...., and the varieties currently grown contain little beta-carotene.这里后半句不是就是给出成功的原因么？D重复了原文结论的意思，所以应该是加强啊？有谁能帮帮解答一下啊。

求好心人帮帮忙啊~~

问题重点是问 加强计划未来成功的可能

最后一句说成功的原因两点1.该地区的主食和农作物 2目前种的含BETA少 。所以选项选要强调两方面的

选项 该地区的种植条件适合SPK大丰收，加强了两者的可实施性
选项 SPK含BETA比其他任何都多，其他都不如SPK，还是没有加强计划的可实施性
