The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect， a generally more healthy body.2 The reduction in leucocyte levels was about 15 percent.(第2题的答案相关句) Lower lymphocyte levels are also indicative of reduced levels of inflammation， but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.
(第3段)In what was the longest study of its kind， pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health. “The use of raw(没有加工的) potato starch(淀粉) in this experiment(实验) is designed to (被设计用于...)simulate(模仿) the effects(效果) of a diet high in resistant starch”， said study leader(与问题句中的核心结构/研究者呼应)(领导者) Jose Francisco Perez at the Universitat Autonoma de Barcelona，3 Spain(西班牙)
答案相关句(第3段第2句)引用了研究组负责人自己的话， 该句说：“在实验中使用未经加工的土豆淀粉，就是为了模拟富含耐久淀粉的饮食所起的作用”，其它A、C、D三个选项文章均没有提及。
4 All of the following(下列的， 其次的) foods are rich in (含有丰富的)resistant(有抵抗力的) starch(淀粉) EXCEPT (除了...)__________.
a) Pasta(意大利面食)
b) Grains(谷物， 粮食)
c) Legumes(豆类)
d) Vegetables(蔬菜， 植物)
4.D. 细节题。 利用问题句中的细节信息结构(resistant starch )及被选项中的细节信息词(黑体词 )共同作为答案线索， 在文章中查找答案相关句：
Eating potatoes is not only good for bowel health， but also for the whole immune system， especially when they come in the form of a potato salad or eaten cold. In a study on an animal model， researchers in Spain found that pigs fed large quantities of raw potato starch (RPS)1 not only had a healthier bowel， but also decreased levels of white blood cells， such as leucocytes and lymphocytes in their blood. White blood cells are produced as a result of inflammation or disease， generally when the body is challenged.

Lower lymphocyte levels are also indicative of reduced levels of inflammation， but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.
In what was the longest study of its kind， pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health. (第3题答案相关句)“The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistant starch”， said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona，3 Spain.
(第4段)Humans do not eat raw(没有加工的) potatoes， but they do eat (的确吃)a lot of (大量的)foods that contain(含有， 容纳) resistant starch， such as (例如)cold(凉的) boiled(煮熟的) potatoes， legumes(豆类)， grains(谷物)， green bananas(香蕉)， pasta (意大利面食)and cereals(谷类食品). About 10 percent of the starch eaten by human is resistant starch - starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments. Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS).4
答案相关句(第4段第1句)列出了一些富含耐久淀粉的食品，其中就没有D项“蔬菜”。
5. What kind of starch(淀粉) is resistant starch after all(终究，毕竟)?
a)It may cause(造成) irritable(易怒的) bowel(肠) syndrome(综合症)(肠易激综合症).
b)It may bring about (造成)at least (至少)partially(部分地) inflammatory(炎症性的) disorder(紊乱).
c)It may raise(提高， 饲养， 募集) leucocyte(白细胞) and lymphocyte (淋巴细胞)levels in the body(身体).
d) It cannot be digested (不能被消化)in the small intestine(小肠) and ferments(发酵) in the large intestine(大肠) .

(第4题答案相关句)Humans do not eat raw potatoes， but they do eat a lot of foods that contain resistant starch， such as cold boiled potatoes， legumes， grains， green bananas， pasta and cereals. About 10 percent of the starch eaten by human is resistant starch - starch that is not digested(消化) in the small intestine and so is shunted(被搁置到...) into the large intestine(大肠) where it ferments(发酵).Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS).4
答案相关句(第4段倒数第2句)已经解释了耐久淀粉的特点：“不能在小肠中消化，而是分流到大肠，在大肠中发酵”。
