二、阅读理解
A
After two decades of steady increases，obesity rates in adults and children in the United States have remained largely unchanged during the past 12 years，a finding that suggests national efforts at promoting healthy eating and exercise are having little effect on the overweight.
Over all,35.7 percent of the adult population and 16.9 percent of children qualify as obese，according to data gathered by the federal Centers for Disease Control and Prevention and published online Tuesday.While it’s good news that the ranks of the obese in America are not growing，the data also point to the intractable nature of weight gain and signal that the country will be dealing with the health consequences of obesity for years to come.
“We’re by no means through the epidemic(流行病)，”said Dr David Ludwig，director of the childhood obesity program at Children’s Hospital in Boston.“Children will be entering adulthood heavier than they’ve ever been at any time in human history.Even without further increases in prevalence(普及)，the impact of the epidemic will continue to mount for many years to come.”
1．During which period did obesity rates in the United States steadily increase?
A．From 1959 to 1979.
B．From 1969 to 1989.
C．From 1979 to 1999.
D．From 1989 to 2009.
解析：推理判断题。根据第一段After two decades of steady increases...remained largely unchanged during the past 12 years...和第四段．..previous surveys collected in twoyear cycles beginning in 1999～2000可推断，答案为C项。
答案：C
2．The underlined word“intractable”in Paragraph 2 is the closest in meaning to“______”．
A．fast to finish
B．hard to manage
C．easy to control
D．anxious to stop
解析：词义猜测题。根据第二段．..signal that the country will be dealing with the health consequences of obesity for years to come可推断，intractable意为“难对付的”，故答案为B项。
答案：B
3．What do we know from David Ludwig?
A．Many children will become thin after growing up.
B．The problem of obesity will become more serious in the future.
C．Childhood obesity is a longterm problem in America.
D．It is not necessary to worry about the problem of obesity.
解析：推理判断题。根据第三段Even without furher increases in prevalence，the impact of the epidemic will continue to mount for many years to come可推断，答案为C项。
答案：C
4．Which of the following groups has become obese in recent years according to the passage?
A．Blacks.
B．Females.
C．Whites.
D．Males.
解析：细节理解题。根据第五段For instance，men and boys have become fatter since 1999...可知，答案为D项。
答案：D
B
A French woman has taught her dogs to play the piano.In a new YouTube video，the dogs sit side by side at an oversize keyboard，perfectly pawing(用爪子扒)the keys in response to musical notes(音符)played by their owner，who accompanies them playing a flute.
It’s quite a unique skill.But what exactly is going on here？Charles Snowdon，a scientist at the University of WisconsinMadison who studies animals’responses to music and is at the top level in the study of how animals respond to“speciesspecific music”，said：“The dogs have been trained to do certain things after getting some signals given by their owner，which is different from memorization.She plays notes and my guess is what the dogs have done is learning the relationship between the notes their owner is playing and where they are supposed to put their paws.So，the dogs most likely can play the correct notes not because they understand which notes sound right，but they’ve been trained to respond to certain sounds of the flute by pressing certain keys on the piano.Or perhaps there are some secrets we can’t see in the video.”
“The trio(三重奏)sounds like a melody(旋律)to us，but the dogs probably don’t know it.It’s not clear whether they listen to it as music，”Snowdon told Life’s Little Mysteries.On the other hand，they might be.Most animals have very different vocal ranges(音域)．Snowdon has worked with musicians to create pieces of music that are more familiar to specific animals.For example，they’ve made some music for monkeys.The songs sound unpleasant to us，but they are music to monkeys’ears.
According to Snowdon，vocal ranges of dogs happen to be quite similar to those of adult male humans.“So，it is possible that they might be responsive to music in our vocal range，”he said.
More research is needed to determine whether dogs really can appreciate human music，or if these stories of dogs are just humoring us.
在一段视频中，一位法国妇女带着她的狗一起演奏，但专家认为狗是在人的暗示下弹琴，它是否懂得人的音乐需要研究才能确定。
5．How can the dogs play the music according to Snowdon?
A．The dogs press the keys as they like.
B．The dogs happen to paw the right keys.
C．The dogs play most likely according to their owner’s signals.
D．The dogs play the music by remembering the notes.
解析：细节理解题。根据第二段The dogs have been trained to do certain things after getting some signals given by their owner...可知，Snowdon说这些狗接受过训练，会根据主人所给的信号做出特定的事情。
答案：C
6．Why does the music that monkeys like sound unpleasant to people?
A．This kind of music needs to be further improved.
B．The vocal ranges of monkeys are especially narrow.
C．The vocal ranges of monkeys and human beings are different.
D．Some people don’t like the style of the music for monkeys.
解析：推理判断题。根据第三段Most animals have very different vocal ranges可知大多数动物都有着不同的音域。可推知，人和猴子的音域可能是不同的，所以猴子喜欢的音乐却会让人类感到不舒服。
答案：C
