it is indeed unfortunate that in our modern era of technologic and

seemingly simple question:
can be done to prevent it
women between the ages of 18 and 79 are
reduce excess weight. This amount to about 377 million kg of excess
fat for men and 667 million kg for women, or a total of 1044
million kg (2297 million 1b) for the United States adult population!
If the overfat men and women dieted by consuming 600 fewer
calories each day to reduce to a
(achievable in 68 days for men and 101 days for women), the
reduced caloric intake would equal 5.7 trilling calories. Translating
this into fossil fuel energy and considering such factors as the energy
required to plant, cultivate, harvest, feed, process, transport,
wholesale, retail, acquire, store and cook the food, the annual
energy savings would be equal to that required to supply the
residential electric demands of Boston, Chicago, san Francisco
and Washington DC, or 13 billion gallons of gasoline to fuel
900,000 autos per year. Until recently, the major cause of obesity
was believed to be overeating. However, if gluttony (贪食) and

overindulgence were the only factors associated with an increase in
body fat, the easiest way to permanently reduce would surely to be
cut back on food. Of course, if it were that simple, obesity would soon
be eliminated as a major health problem. There are obviously other
factors operative such as genetic, environmental, and social
influences. However, these causes probably overlap. It seems fairly
certain that the treatment procedures devised so far, whether they
be diets, surgery, drugs, psychologic methods, or exercise, either
alone or in combination, have not been particularly successful in
solving the problem on a long-term basis. There is nonetheless,
optimism that as researchers continue to investigate the many
facets of. obesity, as well as to test and quantify various treatment
modes, significant progress can be made
21. The complaint made by the writer in the first few lines of
the passage is that

control in our modern era
B) we spend so much money only for making technologic and scientific
achievement
C) the problem of obesity and weight control is so difficult to solve
D)the problem of obesity and weight control needs to be solved only by
doctors

22. The percentage of the excess fat for women of the total amount of
excess fat is roughly
A)50%
C)70%
B)60%
D)40%
23. How much are the calories which would equal the energy required
annually to supply the residential electric demands of Boston, Chicago,
San Francisco, and Washington DC?
A) 13 billion
C) less than 5.7 trillion
B)5.7 trillion
D)more than 5.7 trillion
24. Which of the following should be considered in evaluating the
cause of an overfat person?
A)Indulgence in drinking
B)The genetic, environmental, and social factors
C) All these factors probably overlap
D) Overeating
25. The writer finally says there is optimism for the treatment of
obesity, because
A) various treatment procedures have been devised so far

B) the treatment procedures are particularly successful in solving the
problem on a short-term basis
C) exercise alone can be successful in solving the major health problem
D) significant progress will be made to conquer this majorhealth
problem through the researchers' effort.

答案解析
21.A)这是一道推断 题,询问在文章的开头几行中作者的抱怨是什么。从第一句
话就可以看出作者的抱怨是:“在科技取得巨 大成就的现代社会,竟然解决不了一
个看似十分简单的肥胖问题。”C)不对,因为作者在前几行没有提 及解决肥胖问题
的难度,只是说明一种现象。
22.B)这是一道计算题,询问女性多余脂肪 占总多余脂肪的比率。只要用667除
于1044,即可得到答案。
23.B)这是一道细节 推算题,询问多少热量等同于多少能量。本题看似复杂,其实
很简单。把节食省下的5.7 trillion calories转变成能量就能满足每年供应那么
多城市的电能要求。
24.C)这是一道细节题,询问肥胖的原因。文中明确提到,“ However,there
causes probably overlap.
25.D)这是一道细节题,询问对于 治疗肥胖症持乐观态度的原因。从最后一个句
子即能得出答案。A)不对,因为在文中可以看出,从长远 来看,现有的各种治疗措
施都不是特别成功。

课文讲解：

It is indeed unfortunate that in our modern era of technologic and
scientific achievement, there is no adequate explanation for a
seemingly simple question:
can be done to prevent it
women between the ages of 18 and 79 are
reduce excess weight.
令人遗憾的是，在我们科技 成就的现代，一个看似简单的问题是：“人何以变胖，
如何防止”这个看似简单的问题，却没有足够的解 释。18至79岁的约5，000
万男性和6，000万女性“太胖”，需要减肥。

This amount to about 377 million kg of excess fat for men and 667

1b) for the United States adult population! If the overfat men and
women dieted by consuming 600 fewer calories each day to reduce
to a
101 days for women), the reduced caloric intake would equal 5.7
trilling calories.

这相当于男性约3.77亿公斤多余脂肪，女性6.67亿公斤，或美国成年人口
1. 044亿公斤(2.297亿1b)！如果肥胖的男性和女性每天摄入600卡路里，
以降低身体脂肪的 “正常”值(男性为68天，女性为101天)，那么热量的减少
将相当于5.7先令卡路里。
trilling
英 ['tr?l??] 美 ['tr?l??]

annual energy savings would be equal to that required to supply the
residential electric demands of Boston, Chicago, san Francisco
and Washington DC, or 13 billion gallons of gasoline to fuel
900,000 autos per year
将这 些能源转化为化石燃料能源，并考虑到种植、收获、饲料、加工、运输、批
发、零售、获取、储存和烹饪 食品所需的能源，每年节省的能源将相当于向波士
顿、芝加哥、旧金山和华盛顿特区居民供电所需的能源 ，即每年为90万辆汽车
提供130亿加仑汽油所需的能源。
