    答案與題解:
     1.C 短文開頭第一句就說,“吃土豆有益于腸道健康,而且對(duì)整個(gè)免疫系統(tǒng)也有益,尤其是吃土豆色拉或涼吃”,因此在四個(gè)選項(xiàng)中最有營養(yǎng)的非C項(xiàng)莫屬。
     2.A 第二段第三句說,“淋巴細(xì)胞水平低顯示炎癥水平下降”,故其他B、C、D三個(gè)選項(xiàng)均不正確。
     3.B 第二段第二句引用了研究組負(fù)責(zé)人自己的話說,“在實(shí)驗(yàn)中使用未經(jīng)加丁的土豆淀粉,就是為了模擬富含耐久淀粉的飲食所起的作用”,其他A、C、D三個(gè)選項(xiàng)文章均沒有提及。
     4.D 第四段第一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”,而且實(shí)際上蔬菜也不是富含淀粉的食物。
     5.D 第四段倒數(shù)第二句已經(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”。其他選項(xiàng)個(gè)別詞語雖在短文中出現(xiàn)過,但都不是說明耐久淀粉的。
