题目内容
12.Childhood obesity(41)is considered(consider) one of the most serious health challenges of the 21st century.Obesity can(42)harm(harmful) nearly every organ in a child's body---heart and lungs,muscles and bones,kidneys as well as the hormones(荷尔蒙)(43)that/whichcontrol blood sugar and puberty(青春期).What's worse,young people who are overweight or obese are likely to remain so even when they grow into adulthood,(44)increasing(increase)the risk of developing disease and disability later in life.Globally,an(45)estimated(estimate) 43million preschool children under the age of 5were overweight or obesity in 2010,a 60% increase since 1990.The problem affects countries rich and poor,and places the greatest burden(46)onthe poorest:of the world's 43million overweight and obese preschoolers,35million live in developing countries.By 2020,if the current epidemic(盛行) continues,9% of all preschoolers will be overweight or obese---nearly 60million children.
Obesity rates are higher in adults(47)thanin children.But in relative terms,the U.S.,Brazil,China,and other countries have seen the problem arise more(48)rapidly(rapid) in children than in adults.
Of course,some regions still struggle hard with child(49)hunger(hungry),such as Southeast Asia and Africa.But globalization has made(50)theworld wealthier,and wealth and weight are linked.
分析 儿童肥胖被认为是二十一世纪的最严重的健康问题,肥胖会伤害几乎孩子身体的每一个器官,更糟糕的是,更糟的是,超重或肥胖的年轻人即使长大成人后仍有可能继续生存,这会增加以后患上疾病和残疾的风险.虽然有些地区还在为孩子的饥饿而苦苦奋斗,但是全球肥胖人数却在增加.
解答 41.is considered 考查被动语态.Childhood obesity和consider之间是被动关系,文章叙述的是客观的事情,所以应用一般现在时的被动语态,故填is considered.
42.harm 考查谓语动词.根据空前的情态动词can可知,此处应用harmful的动词原形harm与情态动词can一起构成句子的谓语部分,故填harm.
43.that/which 考查定语从句.先行词the hormones在从句中作主语,所以是定语从句.在定语从句中指物作主语的关系代词是that/which,故填that/which.
44.increasing 考查现在分词.increase 的逻辑主语是young people,它们之间是主动关系,所以用现在分词作状语.故填increasing.
45.estimated考查形容词.根据空前的冠词an以及空后的43 million preschool children可知,此处应用estimate的形容词形式修饰名词children,estimated意为"估计的,估算的,预计的",故填estimated.
46.on 考查介词. place a burden on…是固定短语,意为"为…增加负担",故填on.
47.than 考查连词.根据前面的比较级 higher 可知此处应用than,句意:成人肥胖率比儿童高,故填than.
48.rapidly考查副词. 因为副词修饰动词,所以修饰动词arise应用rapid的副词形式,故填rapidly.
49.hunger 考查名词. 根据句意:当然,有些地区还在为孩子的饥饿而苦苦挣扎,可知此处应用hungry的名词形式,故填hunger.
50.the 考查定冠词.根据world可知此处应用定冠词the,特指世界上独一无二的事物,故填the.
