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(荷爾蒙)(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 兒童肥胖被認(rèn)為是二十一世紀(jì)的最嚴(yán)重的健康問題,肥胖會傷害幾乎孩子身體的每一個器官,更糟糕的是,更糟的是,超重或肥胖的年輕人即使長大成人后仍有可能繼續(xù)生存,這會增加以后患上疾病和殘疾的風(fēng)險.雖然有些地區(qū)還在為孩子的饑餓而苦苦奮斗,但是全球肥胖人數(shù)卻在增加.

解答 41.is considered  考查被動語態(tài).Childhood obesity和consider之間是被動關(guān)系,文章敘述的是客觀的事情,所以應(yīng)用一般現(xiàn)在時的被動語態(tài),故填is considered.
42.harm 考查謂語動詞.根據(jù)空前的情態(tài)動詞can可知,此處應(yīng)用harmful的動詞原形harm與情態(tài)動詞can一起構(gòu)成句子的謂語部分,故填harm.  
43.that/which 考查定語從句.先行詞the hormones在從句中作主語,所以是定語從句.在定語從句中指物作主語的關(guān)系代詞是that/which,故填that/which. 
44.increasing  考查現(xiàn)在分詞.increase 的邏輯主語是young people,它們之間是主動關(guān)系,所以用現(xiàn)在分詞作狀語.故填increasing. 
45.estimated考查形容詞.根據(jù)空前的冠詞an以及空后的43 million preschool children可知,此處應(yīng)用estimate的形容詞形式修飾名詞children,estimated意為"估計的,估算的,預(yù)計的",故填estimated.
46.on 考查介詞. place a burden on…是固定短語,意為"為…增加負(fù)擔(dān)",故填on.         
47.than 考查連詞.根據(jù)前面的比較級 higher 可知此處應(yīng)用than,句意:成人肥胖率比兒童高,故填than.
48.rapidly考查副詞. 因為副詞修飾動詞,所以修飾動詞arise應(yīng)用rapid的副詞形式,故填rapidly.     
49.hunger 考查名詞. 根據(jù)句意:當(dāng)然,有些地區(qū)還在為孩子的饑餓而苦苦掙扎,可知此處應(yīng)用hungry的名詞形式,故填hunger.    
50.the 考查定冠詞.根據(jù)world可知此處應(yīng)用定冠詞the,特指世界上獨(dú)一無二的事物,故填the.

點(diǎn)評 語法填空是通過語篇在語境中考查語法知識的運(yùn)用能力,在解題前應(yīng)快速瀏覽短文掌握大意,在讀懂短文的基礎(chǔ)上,結(jié)合短文提供的特定的語言環(huán)境去逐句分析,逐題解答.扎實的語法功底加上準(zhǔn)確的理解是解答語法填空題的關(guān)鍵.

2.Once there was an 11-year-old boy who went fishing with his father in the middle of a New Hampshire lake.On the day before bass (巴斯魚) season opened,they were fishing early in the evening,catching other fish with worms.Then the boy tied on a small silver lure (魚餌) and put it into the lake.Suddenly he felt that something very big pulling on the lure.His father watched with admiration as the boy skillfully brought the fish beside the bank.Finally he lifted the tired fish from the water.It was the largest one he had ever seen,but it was a bass.
The boy and his father looked at the big fish.The father lit a match and looked at his watch.It was 10 p.m.-two hours before the season opened.He looked at the fish,then at the boy."You'll have to put it back,son,"he said.
"Dad!"cried the boy."There will be other fish,"said his father."Not as big as this one,"cried the boy.He looked around the lake.No other fishermen or boats were in sight in the moonlight.He looked again at his father.
Even though no one had seen them,nor could anyone ever know what time he had caught the fish,the boy could tell from his father's voice that the decision couldn't be changed.He threw the huge bass into the black water.The big fish disappeared.The boy thought that he would never again see such a big fish.
