　　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.

　　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題答案相關(guān)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(沒有加工的) potatoes， but they do eat (的確吃)a lot of (大量的)foods that contain(含有， 容納) resistant starch， such as (例如)cold(涼的) boiled(煮熟的) potatoes， legumes(豆類)， grains(谷物)， green bananas(香蕉)， pasta (意大利面食)and cereals(谷類食品). 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

　　答案相關(guān)句(第4段第1句)列出了一些富含耐久淀粉的食品，其中就沒有D項(xiàng)“蔬菜”。

　　5. What kind of starch(淀粉) is resistant starch after all(終究，畢竟)?

　　a)It may cause(造成) irritable(易怒的) bowel(腸) syndrome(綜合癥)(腸易激綜合癥).

　　b)It may bring about (造成)at least (至少)partially(部分地) inflammatory(炎癥性的) disorder(紊亂).

　　c)It may raise(提高， 飼養(yǎng)， 募集) leucocyte(白細(xì)胞) and lymphocyte (淋巴細(xì)胞)levels in the body(身體).

　　d) It cannot be digested (不能被消化)in the small intestine(小腸) and ferments(發(fā)酵) in the large intestine(大腸) .

　　5.D. 細(xì)節(jié)題。 利用問題句及被選項(xiàng)中的細(xì)節(jié)信息結(jié)構(gòu)(黑體結(jié)構(gòu))作為答案線索，在文章中查找答案相關(guān)句：

　　(第4題答案相關(guān)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(被擱置到...) into the large intestine(大腸) where it ferments(發(fā)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

　　答案相關(guān)句(第4段倒數(shù)第2句)已經(jīng)解釋了耐久淀粉的特點(diǎn)：“不能在小腸中消化，而是分流到大腸，在大腸中發(fā)酵”。
