Question

"It's wrong just to blame mothers for their daughters'eating disorders，"says Susan Ringwood，chief executive of the eating disorders charity，Beat．"There is a genetic（基因的）component to eating disorders．"However，"We do know that parents have a very strong influ．ence over a child's eating．It's important to realize that you are your daughter's role model．Girls idolize the ir mothers．"says Ringwood．
"Nofoodshould ever be‘good'or‘bad'，"Ringwood says．Instead，"You have to make it clear that food is a sociable，healthy and fun part of life，not something to be feared．"
"Talk to her about body image，"Ringwood says．"Talk about how curves are an important and exciting part of being a woman．Show her that anorexic（厌食的）fashion models are not sexy，but i11．The pressure on girls today is immense，"she says．"But don't forget that you are the authoritative voice，too．"

Answer 1

分析 本文讨论的是有关肥胖的问题，研究表明孩子们越节食，成年后越可能肥胖，研究还表明女孩们在饮食习惯及体型方面受母亲影响很大．

解答 AADAD
66．A 细节理解题．由文章第一句Michelle Obama has just started a campaign against childhood obesity（肥胖）可知，奥巴马组织这一活动是为了解决全国儿童的肥胖问题．
67．A 细节理解题．这个例子是为了论证第二段的观点，即girls are highly influenced by their mothers．由此可知，母亲对女儿的饮食习惯有很大的影响．
68．D 细节理解题．由倒数第三段的There is a genetic（基因的）component to eating disorders可知，饮食紊乱和基因组成有关系．
    69．A 主旨大意题  根据Studies show that the more children diet，the more likely they are to become obese as adults．Research also shows that girls are highly influenced by their mothers when it comes to eating habits and body image．可知，研究表明孩子们越节食，成年后越可能肥胖，研究还表明女孩们在饮食习惯及体型方面受母亲影响很大，故答案为A

70．D 推理判断题．文章第二段的…the more children diet，the more likely they are to become obese as adults表明作者也反对儿童的饮食习惯．

点评 1、要想做好科普英语阅读理解题，同学们就要注意平时多读科普知识类文章，学习科普知识，积累常见的科普词汇，从根本上提高科普英语的阅读能力．
2、要熟悉科普类文章的结构特点．科普类文章一般由标题（Head line），导语（Introduction），背景（Back ground），主体（Main body）和结尾（End）五部分构成．标题是文章中心思想高度而又精辟的概括，但根据历年的高考情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题．导语一般位于整篇文章的首段．背景交待一个事实的起因．主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点．结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题．　　
3、在进行推理判断时，同学们一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识．
