Question

12．Michelle Obama has just started a campaign against childhood obesity（肥胖）with the admission that she put her girls Malia and Sasha on a diet because they were getting fat．Clearly，childhood obesity must be solved and urgently．But is it a good idea for mothers to put their daughters on diets？
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．

"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（厭食的）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 本文討論的是有關(guān)肥胖的問(wèn)題，研究表明孩子們?cè)焦?jié)食，成年后越可能肥胖，研究還表明女孩們?cè)陲嬍沉?xí)慣及體型方面受母親影響很大．

解答 AADAD
66．A 細(xì)節(jié)理解題．由文章第一句Michelle Obama has just started a campaign against childhood obesity（肥胖）可知，奧巴馬組織這一活動(dòng)是為了解決全國(guó)兒童的肥胖問(wèn)題．
67．A 細(xì)節(jié)理解題．這個(gè)例子是為了論證第二段的觀點(diǎn)，即girls are highly influenced by their mothers．由此可知，母親對(duì)女兒的飲食習(xí)慣有很大的影響．
68．D 細(xì)節(jié)理解題．由倒數(shù)第三段的There is a genetic（基因的）component to eating disorders可知，飲食紊亂和基因組成有關(guān)系．
    69．A 主旨大意題  根據(jù)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，研究表明孩子們?cè)焦?jié)食，成年后越可能肥胖，研究還表明女孩們?cè)陲嬍沉?xí)慣及體型方面受母親影響很大，故答案為A

70．D 推理判斷題．文章第二段的…the more children diet，the more likely they are to become obese as adults表明作者也反對(duì)兒童的飲食習(xí)慣．

點(diǎn)評(píng) 1、要想做好科普英語(yǔ)閱讀理解題，同學(xué)們就要注意平時(shí)多讀科普知識(shí)類文章，學(xué)習(xí)科普知識(shí)，積累常見(jiàn)的科普詞匯，從根本上提高科普英語(yǔ)的閱讀能力．
2、要熟悉科普類文章的結(jié)構(gòu)特點(diǎn)．科普類文章一般由標(biāo)題（Head line），導(dǎo)語(yǔ)（Introduction），背景（Back ground），主體（Main body）和結(jié)尾（End）五部分構(gòu)成．標(biāo)題是文章中心思想高度而又精辟的概括，但根據(jù)歷年的高考情況來(lái)看，這類閱讀理解材料一般不給標(biāo)題，而要同學(xué)們選擇標(biāo)題．導(dǎo)語(yǔ)一般位于整篇文章的首段．背景交待一個(gè)事實(shí)的起因．主體則對(duì)導(dǎo)語(yǔ)概括的事實(shí)進(jìn)行詳細(xì)敘述，這一部分命題往往最多，因此，閱讀時(shí)，同學(xué)們要把這部分作為重點(diǎn)．結(jié)尾往往也是中心思想的概括，并與導(dǎo)語(yǔ)相呼應(yīng)，命題者常在此要設(shè)計(jì)一道推理判斷題．　　
3、在進(jìn)行推理判斷時(shí)，同學(xué)們一定要以閱讀材料所提供的科學(xué)事實(shí)為依據(jù)，同時(shí)所得出的結(jié)論還應(yīng)符合基本的科普常識(shí)．
