Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet.
In rejecting exercise, some people may be discouraged too much by caloric-expenditure（熱量消耗）charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry(小甜餅). Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports.
Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.
If you have been sedentary (極少活動(dòng)的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
小題1:What is said about the average American in the passage?
A．They tend to hate "light" beer and low-calorie bread.
B．They usually ignore the effect of exercise on losing weight.
C．Most of them were combining exercise with their diet.
D．They know the actors that play a positive role in keeping down body weight.
小題2:"Even exercise professionals accept half a point here" means "They          ".
A．a(chǎn)gree that the calories in a small piece of pastry can be easy to work off by exercise
B．partially believe diet plays a supporting role in weight reduction
C．a(chǎn)re not fully convinced that dieting can help maintain one's new weight
D．a(chǎn)re not sufficiently informed of the positive role of exercise in losing weight
小題3:What was confirmed by the Boston University Medical Center's study?
A．Controlling one's calorie intake is more important than doing exercise.
B．Even occasional exercise can help reduce weight.
C．Weight reduction is impossible without exercise.
D．One could lose ten pounds in a year's time if there's no increase in food intake.
小題4:What is the author's purpose in writing this article?
A．To stress the importance of maintaining proper weight.
B．To support the statement made by York Onnen.
C．To show the most effective way to lose weight.
D．To introduce the study of the Boston University Medical Center.

試題分析：文章大意：文章強(qiáng)調(diào)鍛煉身體對(duì)于減肥和保持體重的重要性，而它的重要性卻常常被美國(guó)民眾忽視。
小題1:細(xì)節(jié)理解題。根據(jù)第一段第二行的“that message has not gotten through to the average American”可知，that message指代第一句，exercise的作用還沒有被美國(guó)的民眾接受。故選B。
小題2:細(xì)節(jié)理解題。根據(jù)第二段“Exercise by itself is a very tough way to lose weight”可知，通過鍛煉身體來減肥比較辛苦，是一種較為困難的方法。第二段舉的例子是為了說明運(yùn)動(dòng)量之大，A項(xiàng)曲解原意；這里講的是exercise，與dieting無關(guān)；專家知道鍛煉的積極作用，而不是要加大宣傳。故選B。
小題3:考查對(duì)段落大意的把握。根據(jù)第三段最后一句“while those who worked exercise into their daily routine maintained their new weight”可知，鍛煉身體可以幫助減肥。故選C。
小題4:考查作者的寫作意圖。作者強(qiáng)調(diào)的是鍛煉身體對(duì)保持體重的重要性，A項(xiàng)偷換概念；York Onnen不完全相信鍛煉身體的積極作用；Boston University的研究只是用來印證鍛煉身體的一個(gè)例子。故選C。

When I wake up on summer mornings, I know I am going to my favorite place to volunteer and make a difference in someone's life just by being with him or her -- a summer school for autistic (患孤獨(dú)癥的)children.
By helping the kids read or do math, I am not only teaching important skills but also helping them feel like any other kid. There are many wrong ideas about autism. The kids I work with can think and feel. They need help only in certain areas. 
Of course, each kid is special. For example, some kids like to draw, and others like to sing.
At the school, the kids learn through about 20 activities. These activities can help them learn skills they will need later in life.
The very first day I volunteered, a boy came up to me, put his hand on my shoulder, and said “Hello”. From then on, I knew I could make a difference.
Another boy loved to have me read books that can help him learn to read. Sometimes he could be encouraged to read a few words or sentences. Finally, one day during reading practice, he read nearly 220 words himself!
Summer school is also a time for fun, Last summer, bagpipe(風(fēng)箱)players came to perform. Most of us had our hands over our ears because they were so loud. When they asked for a volunteer from the audience, one girl raised her hand as high as she could, got up on stage, and even tried the bagpipes in front of everyone.
Through these experiences, I realize that the challenges these kids face do not stop them from doing many amazing things. I'm teaching them, but they are teaching me more.
小題1:According to Paragraph 2, many people think autistic kids _________ .
A．can't read or do mathB．don't have important skills
C．don’t play with other kidsD．can't think or feel
小題2:The phrase “these experiences” in the last paragraph refers to the following EXCEPT ________ .
A．“I” read the books for kids
B．a(chǎn) boy read nearly 220 words himself
C．a(chǎn) girl tried the bagpipes on stage as a volunteer
D．a(chǎn) boy said hello to“ me” politely
小題3:What does the author mainly talk about in the passage?
A．His teaching experience in a summer holiday.
B．How to make a difference in others' lives.
C．His experience as a volunteer in a special summer school.
D．Autistic children's hard life.

To some, it's a dream job---eating delicious meals for free and then writing about them. But for some food critics, their eyes aren't the only thing that gets wide with yet another feast.
Karen Fernau, a food writer for The Arisona Republic, said when she first started her job –she began to gain weight. “I always looked forward to lunch before this job, then all of a sudden lunch was all day every day. " she says. Nine years later, keeping her weight steady and her health intact （完好無損的）is a daily battle. If she knows she will be going to a tasting at a bakery or eating a four-course meal, she usually eats fruits or salads throughout the day. Now she is always keeping track of what's in the food she eats and she says most people don't even look at or consider it. At one tasting task alone, she says, upward of l,000 calories is often added to her day. That's about half of the recommended total calories per day for the average adult.
But even though she's thought of a special eating method, Fernau says sticking to it is a daily battle. And food editors, writers and critics across the country couldn't agree more. “When I'm at home or not eating for work, it's healthy food to the extreme," says Phil Vettel, who's been a restaurant critic for the Chicago Tribune for 19 years.
Vettle, who eats dinner at four restaurants each week, says unlike most professions, he has no right to choose. "If I'm going out to eat, I can't choose the healthiest thing on the menu, I have to eat when they're bringing me. " While Vettel exercises when he can, Joe Yonan, a food editor at The Washington Post, has strengthened his exercise habits since he started the job two years ago. Yonan says he realized early on that he was gaining weight and immediately hired a personal trainer to meet with three times a week, on top of his body training three to five times a week.
Still, it's a struggle that many Americans might envy. After all, it's one thing to get your calories from lobster（龍蝦） tails or a delicate（精致的）chocolate cookie and quite another to get them from sodas and fast-food burgers.
小題1:What does the underlined sentence mean in Para l?
A．The food critics are always impressed by the delicious food in the restaurant.
B．The food critics are shocked to learn they have to have one more feast.
C．There is a wide variety of choices for the food critics to choose from.
D．The food critics eat delicious food, which also tends to result in gaining weight.
小題2:What can we learn about the job of being a food critic?
A．They enjoy free and delicious dishes and make comments on them.
B．They only work for local magazines and newspapers.
C．Once they become food critics, they tend to stay in the job.
D．Their excellent sense of taste makes them qualified for the job.
小題3:What is mentioned to be a method that food writers use to keep fit?
A．Not eating anything except for the free meals.
B．Writing down everything they put into their mouth.
C．Hiring a personal trainer for special exercise instructions.
D．Choosing only the healthy food on the menu.
小題4:What can we infer from the last paragraph?
A．No matter whether the food is expensive or not, the gaining of calories is the same.
B．The calories that lobster tails and chocolate cookies contain are less harmful.
C．Americans envy those food critics since they enjoy delicate and tasty food.
D．Everybody should take the calories in their food carefully.
小題5:What's the main idea of the passage?
A．A job offering free meals may not be as desirable as it sounds to be.
B．Dishes in the restaurant usually contain too many calories.
C．Eating fruits and vegetables every day is the best way to lose weight.
D．Food writers work hard to maintain their health and weight.

This week is National Volunteer Week, a time for the Canadian Red Cross to recognize our dedicated (有奉獻(xiàn)精神的) volunteers who devote their time and talents from coast to coast. Over the course of the week we will use this blog to share stories about our volunteers and the amazing work they do --- a small part of the outstanding individuals across the country.
Take Saskatchewan for example. Last year that province was hit by wide-spread flooding, a hurricane and forest fires. Canadian Red Cross staff and volunteers went to work right away and helped more than 2,100 adults and 775 children recover the basic necessities of life.
It’s important to share stories from volunteers to truly appreciate what they do. Christine Hoffman is a Disaster Response Volunteer in Canadian Red Cross in Saskatchewan. She’s a veteran Red Crosser for about 16 years. Still nothing could have prepared her for the call she took in the Recovery Center last year in response to flooding in Maple Greek. This story is best told in her own words. This is what she said:
“I will never forget the first phone call I took in the Recovery Centre. A young man called asking what services Red Cross was offering in town. As we were talking, he told me he had a rope in his backyard but he thought he would be using it for other reasons. My heart stopped. I told him to come to see us so we could work together on a plan to improve his situation. He came in a little while later. Nearly two hours later he left standing straight up with tear- filled eyes. He thanked me for convincing him to come in. His home had been destroyed, but together we put together a plan and he was eventually able to move back into his own home.”
During National Volunteer Week 2011, let’s thank Christine, and the many other volunteers like her. Thanks for making us proud!
小題1:According to the second paragraph, Canadian Red Cross’ action is ______
A．slowB．quickC．helplessD．disappointing

What does it mean to say that we live in a world of persuasion? It means that we live among competing interests. Your roommate’s need to study for an exam may take priority over pizza. Your instructor may have good reasons not to change your grade. And the object of your romantic/inter­est may have other choices.
In such a world, persuasion is the art of getting others to give fair and favorable consideration to our points of view. When we persuade, we want to influence how others believe and behave. We may not always prevail — other points of view may be more persuasive, depending on the listener, the situ­ation, and the merit of the case. But when we practice the art of persuasion, we try to ensure that our position receives the attention it deserves.
Some people, however, object to the very idea of persuasion. They may regard it as an unwelcome interruption into their lives. Just the opposite, we believe that persuasion is unavoidable — to live is to persuade. Persuasion may be ethical or unethical, selfless or selfish, inspiring or degrad­ing. Persuaders may enlighten our mind or prey on our vulnerability. Ethical persuasion, however, calls on sound reasoning and is sensitive to the feelings and needs of listeners. Such persuasion can help us apply the wisdom of the past to the decisions we now must make. Therefore, the most basic part of edu­cation is learning to resist the one kind of persuasion and to encourage and practice the other.
Beyond its personal importance to us, persuasion is necessary to society. The right to persuade and be persuaded is the bedrock of the American political system, guaranteed by the First Amendment to the Constitution.
小題1:According to the passage, persuasion means ________.
A．changing others’ points of view
B．exercising power over other people
C．getting other people to consider your point of view
D．getting people to agree with you and do what you want
小題2:The underlined word in the second paragraph “prevail” means________.
A．win B．failC．speakD．listen
小題3:The passage states that some people object to persuasion because they think it is ________.
A．a(chǎn) danger to societyB．difficult to do well
C．unwelcome behaviorD．never successful
小題4:The passage mainly discusses ________.
A．how people persuade
B．why people persuade
C．that persuasion is both good and bad
D．that persuasion is important and it is all around us

What’s in name? Well, apparently, our general happiness. Psychologists say that what we are called has a direct connection with our happiness.
Those called Judy and Joshua are the happiest, while Lynn or Ben is likely to be the unhappiest, according to research. Psychologist Dr David Holmes found that this can cause the association(聯(lián)想) that others make with the name. Hearing the name Judy may make them think of actress Judi Dench or TV presenter Judy Finnigan, and people who are considered good-natured and happy. On the other hand, people think Paulines are unhappy because of the character Pauline Fowler from the TV programme East Enders. The research claims that this association influences the person with the name and so their personality is shaped to fit in. Dr David Holmes said, “This also has some relation with the original meaning of the name, for example, the original meaning of Judy is ‘praised’.”
Certain names also work well in certain aspects of life. In the workplace Richard and Judy are the happiest, while those called Ruth and Carly are the happiest in relationships. At the other end of the scale the unhappiest workers are Stuart and Liz, with the unhappiest in relationships being Frank and Harriet.
Dr Holmes said, “The relation we have with certain names, particularly important namesakes (同名者), also shapes how we see ourselves and so may have an effect on our confidence. Names are like product brands in having a powerful effect on attitudes and should therefore be chosen with care.”
“Other names are connected with being brave, outgoing or serious. Therefore, many celebrities change their names to ones which reflect these characteristic. This, in turn, influences parents when they choose names for their babies,” said Dr Holmes, “while names connected with ordinary people are rarely chosen for their babies.”
小題1:What’s the main idea of this passage?
A．How to choose a good name for babies.
B．The relation between names and happiness.
C．How to have a name connected with celebrities.
D．The relation between names and success.
小題2:According to the passage, which of the following names are better?
A．Joshua and Ben.B．Pauline and Frank.
C．Richard and Stuart.D．Ruth and Joshua.
小題3:The author may continue the passage with _________.
A．names and product brands
B．famous people’s names
C．names and personality
D．parents’ choices of baby names
小題4:Which of the following is connected with names according to the passage?
A．Personality and self-confidence.B．Self-confidence and position.
C．Position and characteristic.D．Personality and appearance.

It’s such a happy-looking library, painted yellow, decorated with palm-tree stickers and sheltered from the Florida sun by its own roof. About the size of a microwave oven, it’s pedestrian-friendly, too, waiting for book lovers next to a sidewalk in Palm Beach country Estates, along the northern boundary of Palm Beach Gardens.
It’s a library built with love.
A year ago, shortly after Janey Henriksen saw a Brian Williams report about the Little Free Library organization, a Wisconsin-based nonprofit that aims to promote literacy and build a sense of community in a neighborhood by making books freely available, she announced to her family of four, “That’s what we’re going to do for our spring break!”
Son Austin, now a 10th-grader, didn’t see the point of building a library that resembles a mailbox. But Janey insisted, and husband Peter unwillingly got to work. The 51-year-old owner of a ship supply company modified a small wooden house that he’d built years earlier for daughter Abbie’s toy horses, and made a door of glass.
After adding the library’s final touches (裝點(diǎn)), the family hung a signboard on the front, instructing users to “take a book, return a book,” and making the Henriksen library, now one of several hundred like it nationwide and among more than 2,500 in the world, the only Little Free Library in Palm Beach County.
They stocked it with 20 or so books they’d already read, a mix of science fiction, reference titles, novels and kids’ favorites. “I told them, keep in mind that you might not see it again,” said Janey, a stay-at-home mom.
Since then, the collection keeps replenishing (補(bǔ)充) itself, thanks to ongoing donations from borrowers. The library now gets an average of five visits a day.
The project’s best payoff, says Peter, are the thank-you notes left behind. “We had no idea in the beginning that it would be so popular.” (317 words)
小題1:In what way is the library “pedestrian-friendly”?
A．It owns a yellow roof.B．It stands near a sidewalk.
C．It protects book lovers from the sun.D．It uses palm-tree stickers as decorations.
小題2:Janey got the idea to build a library from __________.
A．a(chǎn) visit to Brian WilliamsB．a(chǎn) spring break with her family
C．a(chǎn) book sent by one of her neighborsD．a(chǎn) report on a Wisconsin-based organization
小題3:The library was built __________.
A．by a ship supply companyB．on the basis of toy horses
C．like a mailboxD．with glass
小題4:What can we infer about the signboard?
A．It was made by a user of the library.B．It marked a final touch to the library.
C．It aimed at making the library last long.D．It indicated the library was a family property.
小題5:The passage tells us that the users __________.
A．donate books to the library
B．get paid to collect books for the library
C．receive thank-you notes for using the library
D．visit the library over 5 times on average daily
