Breastfeeding can reduce the risk of a heart attack or stroke later in life and could prevent hundreds of __1__ of deaths each year，researchers said on Friday.
1. B分析：hundreds of thousands of是固定搭配，表示成千上万之意。
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 prone to sth./ 倾向于...，容易...
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。
3. A)against B) towards
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.
3. A。分析：被选项是介词，因此注意搭配结构：effect通常是和介词 on搭配，但被选项中没有该介词，再注意搭配结构语意..心血管疾病具有保护性的影响，因此判断A合适。
against: prep. 靠着, 反抗, 与相反, 预防
lean against the tree斜靠着树
struggle against fate同命运抗争
protection against the cold预防感冒
4. A)forms B) cases
C) terms D) places
5. A)two B) four C) three D) five
Diets that promote more rapid growth put babies at risk many years later in __4__ of raising their blood pressure，raising their cholesterol and increasing their tendency to diabetes and obesitythe __ 5 __ main risk factors for stroke and heart attack.said Professor Alan Lucas of the Institute of Child Health in London.
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.
6.A.分析：A和B是正反项，重点注意。根据句意和前句中提到的内容 婴儿的头几周和头几个月发育缓慢，对预防心血管疾病有帮助， 由此判断A是答案。
7. A)which B) that
C) something D) anything
Lucas said the effects of breastfeeding on blood pressure and cholesterol later in life are greater than __7 __adults can do to control the risk factors for cardiovascular disease, other than taking drugs.
7.D.分析：根据语法结构和句意判断D合适。

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。
9. A)who B) such
C) when D) taken
Lucas and his colleagues compared the health of 2 1 6 teenagers __9__as babies had either been breastfed or given different nutritional baby formulas.
9.A.分析：空格处需要引导定语从句并修饰人的连接代词who。
10.A)thoughtsB) findings
C) viewpoints D) breakthrough
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。
12.A)despite B) warning
C) regardless D) needful
13. A) smaller B) greater
C) faster D) worse
The researchers also found that，__12 __ of the childs weight at birth，the faster the infants grew in the early weeks and months of life，the __13__ was their later risk of heart disease and stroke.

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。
补充：
the more ..., the more ... 越越
e.g. The more angry he became, the more she laughed at him. 他越生气，她就越笑他。
the more ..., the less ...越越不

14. A) true B) right
C) proper D) same
