　　2. A)likely

　　B) possible

　　C) easy D) prone

　　Babies who are breastfed have fewer childhood infections and allergies and are less __2__ to obesity.

　　2. D. 分析：因为空格后跟的是介词to ，能和介词to搭配使用的只有prone。

　　be likely/possible/ easy to do sth.

　　The train is likely to be late.

　　补充：

　　Easy come easy go 来得容易去得快。

　　C) onto D) upon

　　British scientists have now shown that breastfeeding and slow growth in the first weeks and months of life has a protective effect __3 __ cardiovascular disease.

　　against: prep. 靠着, 反抗, 与相反, 预防

　　lean against the tree斜靠着树

　　4.C. 分析：与介词in 和of构成的固定搭配结构是：

　　in case of

　　in terms of

　　form和place不与in 和of形成固定搭配， 但也可以形成临时性的搭配结构， 如：

　　in the forms of.../以...的形式

　　in the places of.../在...的地方

　　因此判断C是答案。

　　5.B. 分析：前句中先后提到了血压、胆固醇、糖尿病和肥胖，共计四项。

　　6. A)slowly B) quickly

　　C) strongly D) obviously

　　Our evidence suggests that the reason why breast-fed babies do better is because they grow more __6 __ in the early weeks.

　　C) something D) anything

　　8.A)various B) heart

　　C) cardiovascular D) multiple

　　An estimated 17 million people die of __8__ disease，particularly heart attack and strokes，each year，according to the World Health Organization.

　　8.C. 分析：选项C是文章主题词， 因此该选项成为答案的可能性较大。空格后出现的是单数名词，因此排除修饰复数名词的形容词various和 multiple ， 空格已经提到了心脏病发作，所以判断C)出现在空格处合适。

　　C) when D) taken

　　They reported their__10__ in The Lancet medical journal.

　　10.B.分析：上文提到了他们的调查研究，接下来应该出现的是他们的研究结果。

　　11.A)surveyed B) interviewed

　　C) handled D) breastfed

　　The teenagers who had been __11__had a 14一percent lower ratio of bad to good cholesterol and lower concentrations of a protein that is a marker for cardiovascular disease risk.

　　11.D.分析：D是文章主题词，因此成为答案的可能性较大。从句意看， 该句讲述曾经...的青少年中坏胆固醇与好胆固醇的比率要低14%，而且他们的蛋白质积聚也较低，而蛋白质的积聚是患心血管疾病风险高低的标志之一。文章主题是母乳喂养能够减少心血管疾病的危险， 由此推测出现这种较好健康情况的人应该是母乳喂养的人， 因此D是答案。

　　13.B.分析：根据前文内容判断，婴儿前期生长越快， 他们患心脏病的风险越大。
