21．（6分）An image is worth a thousand kilos? Okay, so maybe not a thousand kilos, exactly, but a study shows how a photo diary can keep dieters motivated, making them more likely to achieve their target weight.
Elias Kuzmar Daza, a medical professional from Colombia, studied the motivation levels of patients on weight loss programs at a nutrition clinic.
Different measurements were taken of the patients each week, including body mass index (指标) food and exercise diaries, etc. to record their progress. In addition, full-body photographs were taken each week, which proved to be very motivating and a key factor in patients completing the full program.
Over the course of the sixteen-week program, a full ninety percent of patients, aged between 16 and 72, saw the treatment through to the end, with seventy percent successfully meeting their weight loss aims. Among those monitored, one measurement proved particularly motivating: waistline.
This finding indicates that the majority of the patients who attended the clinic did so motivated by image, rather than any underlying condition. It should be pointed out that eighty percent of them were female.
Another useful finding of this study was that patients did not necessarily need to attend the clinic in person for the program to be effective. A support line was set up, which patients could call to submit their measurements. They also took and sent their own full-body photographs to the researcher. Fifty percent of patients completed the program in this way.
Summarizing the findings, Kuzmar says: “What patients want is a photo, rather than cold numbers.” These photos serve as visual confirmation that all their hard work is paying off, encouraging them on to further weight loss.
1、What is the purpose of the study?
A．To show losing weight is very easy.
B．To compare several ways to lose weight.
C．To prove the effect of images in weight losing.
D．To see how many people can lose weight successfully.
2、How many patients in the clinic reached their weight-loss goals?
A．50%. B．70%.
C．80%. D．90%.
3、What can give people most motivation when they are trying to lose weight?
A．Fri ends’ encouragement. B．Others’ strong muscles.
C．Their slimmer waistline. D．Their standard blood pressure.
4、What must the patients do to complete the weight-loss program?
A．Go to the clinic every week.
B．Call to submit their measurements.
C．Report to the professional every day.
D．Take full-body photographs each week.
22．（8分）Living in a culture that is different from your own can be both an exciting and challenging experience. The following are 6 cultural differences between China and the USA to help promoting mutual understanding.
Money
As is well known, the Chinese are conservative when they are planning to spend money, but far fewer American families are saving money for emergencies and education than their Chinese counterparts (对等的人)..
Privacy
Chinese people do not have the same concept of privacy as American do. They talk about topic such as ages, income or marital (婚姻的) status, which Americans think is annoying and disturbing.
Family
In China, elders are traditionally treated with great respect while young are cared for. In America, the goal of the family is to encourage independence, particularly that of the children. Unlike the Chinese, older Americans seldom live with their children.
Friends
Chinese people have different meanings to define friends. Just hanging out together time to time is not friendship. Friendship means lifelong friends who feel it deeply necessary to give each other whatever help might seem required. Americans always call people they meet friends, so the definition of friends is general and different. There are work friends, playing friends, school friends and drinking friends.
Education
Chinese people value education and career more than Americans, who in turn attach more great importance to good character and faith, which they think are of great value in their life.
________
Basically China values the community and the USA values the individual. If you achieve something in the USA, it’s because you are great. While in China, if you achieve something, it’s because the team, or family, or company is great. Everything you do gets owed to the greater whole, while in American individual achievements are celebrated.
1、What can be inferred from the passage?
A．Americans lay more stress on faith and good personality.
B．Americans think much of the individual and the community.
C．Americans are mean with money to spend while Chinese are not.
D．Americans define friendship almost the same.
2、Which of the following can best describe the last difference?
A．Achievements B．Individual
C．Team VS Individual D．Teamwork
3、What is the purpose of writing the passage?
A．To promote friendship between China and the USA．
B．To help Chinese live well in the USA．
C．To have a complete understanding of the USA．
D．To introduce the cultural differences between China and the USA
23．（8分）After two years of careful consideration, Robert McCrum has reached a conclusion on his selection of the 100 greatest novels written in English. Take a look at a few in his list:
The Pilgrim’s Progress by John Banyan (1678)
A sto ry of a man in search of truth told with the simple clarity and beauty of Bunyan’s prose makes this an English classic.
Robinson Crusoe by Daniel Defoe (1719)
By the end of the 19th century, no book in English literary history had enjoyed more editions and translations. This world-famous novel is a complex literature that one cannot resist.
Gulliver’s Travels by Jonathan Swift (1726)
A great work that’s been repeatedly printed, Jonathan Swift’s Gulliver’s Travels comes third in our list of the best novels written in English.
Clarissa by Samuel Richardson (1748)
Clarissa is a tragic heroine, pressured by her dishonorable family to marry a wealthy man she dislikes, in the book that Samuel Johnson described as “the first book in the world that shows the knowled ge about the human heart”.
Tom Jones by Henry Fielding (1749)
Tom Jones is a classic English novel that gets the spirit of its age and whose characters are well-known since they have come to represent the society at that time.
Emma by Jane Austen (1816)
Ja ne Austen’s Emma is her most outstanding work, mixing the best parts of her early books with a deep sense of feelings.
The Narrative of Arthur Gordon Pym of Nantucket by Edgar Allan Poe (1838)
Edgar Allan Poe’s only novel—a classic adventure story with supernatural elements—has fascinated and influenced generations of writers.
1、Which English book has got the most translations before the 20th century?
A．Robinson Crusoe. B．Gulliver’s Travels.
C．Tom Jones. D．Emma.

A．Their classic lifestyles.

C．Their typical spirits of the age.
D．Their representation of the society.
24．（8分）Life doe sn’t always turn out the way we’d like. When situations take an unfavorable turn, we become upset, frustrated, or angry. When others don’t agree with us, or act in a manner we find disturbing, anger is a typical response. With the exception of a few extreme circumstances? an angry reaction rarely improves the situation or helps us change our mind. Thoughtful consideration of what feelings and reaction are most helpful actually restores our real power, so consider the following alternatives to anger.
Compassion, consisting of both understanding and empathy, can be a perfect solution to anger. Each person has a right to live life according to their beliefs, dreams, needs, etc. If someone is acting improperly
or not living up to our ideals, we need to remove th e “shoulds” and remind ourselves that it is a necessary part of their life’s journey. Choosing this alternative response softens one’s heart and prevents anger from arising.
Humor is another powerful tool for lessening anger. We take life and personal offense far too seriously. After all, their behavior is a reflection of their internal environment and has nothing at all to do with us and it is in reality relatively unimportant. Humor puts any serious situation into its proper places. It acts as a protective barrier to emotional pain as we recognize that what is happening has nothing at all to do with us.
So when others behave badly, forgive them for their bad behaviors rather than judge them in your heart. When life hands us the exact opposite of what we requested, make light of it, After all, this life is only temporary so why get so bent out of shape when it isn’t in line with your ideals? Rain on your wedding day? Break oat the umbrellas and boots and dance in the puddles!
1、What can we infer from the first paragraph?
A．Anger makes a person more powerful.
B．All the people get annoyed easily.
C．Anger often does no good to the situation.
D．Anger can do something good in most cases.
2、How should we respond to others’ misbehavior according to the second paragr aph?
A．Criticize it sharply. B．Complain about it.
C．Leave it as it is. D．Understand and accept it.
3、What does the underlined phrase mean in the last paragraph?
A．Dull. B．Angry.
C．Delighted. D．Gifted.
4、What’s the best title of the passage?
A．Alternative Responses to Anger.
B．The Bad Effects of Anger.
C．The Causes of Frequent Anger.
D．The Risk of Getting Angry.
25．（10分）Academic learning is usually in the spotlight at school, but teaching elementary-age students “soft” skills like self-control and how to get along with others might help to keep at-risk kids out of criminal trouble in the future.
Once a program called Fast Track was started in the early 1990s for more than 7,600 children of 55 schools in America. They were identified by their teachers and parents to be at high risk for developing aggressive behavioral problems. The students were randomly divided into two groups; half took part in the intervention, which included a teacher-led curriculum, parent training groups, academic tutoring and lessons in self-control and social skills. The program, which lasted from first grade through 10th grade, reduced delinquency(少年犯罪), arrests and use of health and mental health services as the students aged through adolescence and young adulthood.
In another latest study, by looking at the data from nearly 900 students in previous findings, researchers found that about a third of the influence on future crime outcomes was due to the social and self-regulation skills the students learned from ages 6 to 11.
The academic skills, or hard skills like learning of physics, which were taught as part of Fast Track, turned out to have less of an influence on crime and delinquency rates than did the soft skills, which are associated with emotional(情绪的) intelligence. Soft skills might include teaching kids to work cooperatively in a group or teaching them how to think about the long-term consequences when they make a decision.
Researchers drew the conclusion that these soft skills should be emphasized even more in our
education system and in our system of socializing children. Parents should do all they can to promote these skills with their children as should education policymakers. To the extent we can improve those skills, we can improve outcomes in delinquency.
1、Fast Track was intended for children who .
A．were randomly chosen from their schools
B．had some problems with academic learning
C．often went against their teachers and parents’ wishes
D．were considered to have criminal trouble in the future
2、What can be learned about "the intervention" in Paragraph 2?
A．It included all the students.
B．It focused on social skills.
C．It improved health services.
D．It had positive outcomes.
3、Compared with soft skills, hard skills .
A．almost have no influence on students
B．are more affected by students’ emotion
C．are mainly related to academic learning
D．offer children greater self-control abilities
4、Which is the best title for the passage?
A．Soft Social Skills Matter
B．Fast Track Helps Children
C．How to Prevent Delinquency
D．What to DO for Education
