16.People who are slightly overweight or mildly obese(肥胖的) have a lower risk of early death than normal weight individuals(个人;个体),according to a new analysis of nearly 100international studies.The studies,most conducted within the past decade,included about three million adults from around the world.The result of these studies by researchers at the National Center for Health Statistics in Maryland,part of the U.S.Centers for Disease Control and Prevention,shows that slightly overweight or obese people were six percent less likely to die from all causes compared to people of normal weight.But the researchers found that seriously obese individuals were still at a 30percent greater risk of death compared to healthy-weight individuals.
Study lead author Katherine Flegal says she was not surprised that overweight people would not have a higher death risk."Because we'd actually already read a lot of this literature and realized that death rates for overweight would be at least not higher than normal[weight,"she said."I guess l was a little bit surprised that it was definitely lower.And l was also surprised that the lower rates of obesity didn't seem to differ from normal weight."
But Flegal stresses the difference in death rates appear to be small between normal-weight people and overweight and mildly obese individuals.
The finding by Flegal and colleagues have raised new questions about the reliability(可靠性)of the so-called"body mass index"or BMI,a measurement of body fat as a ratio(比例,比率)of height to weight,that has become popular in recent years among public health experts to measure potential health risks.
But Heymsfield warns that individuals should not conclude that it's okay to put on extra kilograms,since being at a healthy weight lowers the risk for heart disease and diabetes.
25.Katherine Flegal feels surprised at the fact thatB.
A.obese people have higher death rates
B.slightly obese people have lower death rates
C.obese people tend to die early
D.death rates have nothing to do with body weight
26.What do we learn from the fifth paragraph?A
A.BMI may not be so reliable.
B.The study provides further evidence for BMI.
C.BMI tells nothing about potential health risks.
D.BMI has been much questioned recently.
27.What can we conclude from the passage'?B
A.It's OK to put on extra weight.
B.It doesn't matter if you are slightly obese.
C.Obese people are much healthier.
D.Body weight has nothing to do with death rates.
28.What topic does the passage mainly deal with?C
A.Technology. B.Dieting.
C.Health. D.Death.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了研究发现轻度肥胖的人死亡率较低,因此轻度肥胖不损害健康.
解答 25.B.细节理解题.根据第二段I guess l was a little bit surprised that it was definitely lower.And l was also surprised that the lower rates of obesity didn't seem to differ from normal weight可知Katherine Flegal感到惊讶对于轻度肥胖的人死亡率较低;故选B.
26.A.推理判断题.根据最后一段But Heymsfield warns that individuals should not conclude that it's okay to put on extra kilograms,since being at a healthy weight lowers the risk for heart disease and diabetes可知BMI可能不那么可靠;故选A.
27.B.推理判断题.根据第一段People who are slightly overweight or mildly obese(肥胖的) have a lower risk of early death than normal weight individuals可知轻度肥胖是没关系的;故选B.
28.C.推理判断题.根据第一段People who are slightly overweight or mildly obese(肥胖的) have a lower risk of early death than normal weight individuals可知这篇文章主要讨论健康问题;故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.

Some talked of jobs they already had; others talked of jobs they (43)Aget.With the certainty of four years of college,they felt ready and able to take (44)Bof the world.

(48)Bthey entered the classroom.The professor passed out the papers.And smiles(49)Aon the students'faces as they noted there were only five essay-type questions.
Three hours had passed(50)Cthe professor began to collect the papers.The students no longer looked confident.On their faces was a frightened expression.Papers in hand,no one spoke as the professor faced the class.
He looked at the(51)Bfaces before him,and then asked,"How many completed all five questions?"(52)Aa hand was raised.
"How many answered four?"Still no hands.
"Three?Two?"The students moved restlessly in their seats.
"One,then?Certainly somebody finished (53)C."But the class remained silent.
The professor put down the papers."That is exactly what I (54)D,"he said."I just want to impress upon you that,(55)Dyou have completed four years of engineering,there are still many things about the (56)Byou don't know.These questions you couldn't answer are relatively (57)Cin everyday practice."Then smiling,he added,"You will all (58)Athis course,but remember-even though you are now college graduates,your education has just (59)A."
The years have(60)Dthe name of this professor,but not the lesson he taught.
