The United States of America is the most culturally diverse(多样化) country in the world in terms of culture religion, ethnicity(种族) and sexual orientation. As a combination of various races and cultures, America is home to all. The culture here is so unique that citizens can be just as proud of their original cultural heritage(遗产) as they are to be American.
What is now the US was initially inhabited(居住) by native people until the land was settled by various European groups and African slaves. Since the 20th century, the country has become a heaven for people from all over the globe(全球).
The arrival of immigrants(移民) has shifted populations from rural(农村的) areas into cities because immigrants tend to settle in urban areas. At present, 81 percent of the inhabitants in the US live in cities.
Cultural and ethnic diversity adds a unique flavor to cities that is expressed through distinct(独特的) neighborhoods, restaurants, places of worship, museums, nightlife and multicultural learning environments.
Unique musical forms, such as jazz, rock and roll, Chicano music, and the blues, grow in the US by mixing a variety of culturally distinct musical traditions to create a new form.
At the executive (行政的) level, the country is headed by a mixedrace president; two posts(职位) on the Supreme Court are held by members of the country's two largest minorities.There is also diversity in state and local governments.
Without its rich mixture of races and cultures, America would not be the nation that it is today. Founded upon the basis of equality and freedom, America acts as a stage where different cultures not only coexist peacefully, but develop well.According to the passage, America is a country________.

People who are cheerful and relaxed are less likely to suffer from colds. It’s possible that being full of vim and vigor helps the body fight illnesses, say the researchers from Carnegie Mellon University (CMU) in Pittsburgh.
“We need to take more seriously the possibility that a positive emotional style is a major player in disease risk,” says psychologist Sheldon Cohen, the study’s lead researcher.
In a previous study, Cohen and his colleagues found that people who tended to be cheerful and lively were least likely to develop sniffles, coughs, and other cold symptoms(症状).
Those findings were interesting, but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead, it was still probable that a person’s underlying personality is what matters.
Evidence suggests, for instance, that certain people are naturally more likely to be outgoing and optimistic, with high self-respect and a sense of control over life. This would mean that who we are, not how we feel, finally decides our chances of catching colds.
To figure out which mattered more (personality or emotions), the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. They told the researchers about the positive and negative feelings they had experienced that day.
The results showed that everyone in the study was equally likely to get infected. Their symptoms, however, differed depending on the types of emotions that they had reported over the previous 2 weeks.
Among those who reported good moods and had been infected with the flu virus, for example, 28 percent developed coughs and stuffy(堵塞)noses. On the other hand, those symptoms struck 41 percent of people who had been less positive. Scientists argue about whether negative emotions or positive emotions have a stronger effect on how healthy we are. For now, it can’t hurt to look on the bright side more often than not! What is the text mainly about?
| A．how to get rid of colds | B．Attitude determines life |
| C．Smiles turn away colds | D．Different opinions about colds |
The word “full of vim and vigor” underlined in Paragraph 1 probably means_______.
| A．ignorant | B．well-informed | C．energetic | D．in low spirits |
According to the finding a leading factor of catching colds should be one’s _______.
| A．health. | B．personality. | C．quality | D．mood |

Not many years ago, a wealthy and rather strange old man named Johnson lived alone in a village in the south of England. He had made a lot of money in trading with foreign countries. When he was seventy – five, he gave $ 60,000 to the village school to buy land and equipment for a children’s ground.
As a result of his kindness, he became famous. Many people came to visit him. Among them was a newspaperman. During their talk, Johnson remarked that he was seventy-five and expected to live to be hundred. The newspaperman asked him how he managed to be healthy at seventy-five. Johnson had a sense of humor. He liked whisky and drank some each day. “I have an injection (注射) in my neck each evening,” he told the newspaperman, thinking of his evening glass of whisky.

Students who date in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia.
"Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.
Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.
Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students’ academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.
"At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,” according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters.
"Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying.”
“Dating should not be considered a ceremony of growth in middle school,” Orpinas concluded. According to the passage, students who date in middle school may_____
| A．have poorer academic performances |
| B．be more likely to hurl others |
| C．enjoy better school lives |
| D．are less likely to use alcohol and tobacco |
When doing his study, Orpinas_____.
| A．followed a group of students of 6th and 12th grade |

| C．completed questionnaires about the students’ academic efforts |
| D．found that the students’ study skills have connection with their frequency of dating |
Study skills may include the following behaviors and qualities Except_____
| A．being diligent | B．being well organized |
| C． being kind and helpful | D．finishing assigned schoolwork |
What can possibly happen to the school couples after they break up?
| A．They don’t want to see each other any longer. |
| B．Their attention to studying will be affected. |
| C．They will miss their ex-partners sometimes |
| D．They will think it reasonable to get depressed. |
Orpinas’ attitude towards dating in middle school is_____

Each new school year brings fresh reminders of what educators call the summer learning gap. Some call it the summer learning setback（退步）. Simply speaking, it means the longer kids are out of school, the more they forget. The only thing they might gain is weight.
Most American schools follow a traditional nine-month calendar. Students get winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight weeks at a time, with a few weeks off in between. The National Association for Year-Round Education says there were fewer than three thousand such schools at last count. They were spread among forty-six of the fifty states.
But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school. Lead researcher Paul von Hippel said, “Year-round schools don't really solve the problem of the summer learning setback. They simply spread it out across the year.”
Across the country, research shows that students from poor families fall farther behind over the summer than other students. Experts say this can be prevented. They note that many schools and local governments offer programs that can help.
But calling them “summer school” could be a problem. The director of the summer learning center at Johns Hopkins, Ron Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term “summer school”. In American culture, the idea of summer vacation is connected to beliefs about freedom and the joys of childhood. The parents welcomed other terms like “summer camp”, “enrichment”, “extra time” and “hands-on learning”. According to the first paragraph the summer learning gap .
| A．helps children to gain weight |
| B．leads children to work harder |
| C．improves children’s memories |
| D．affects children’s regular studies |
Compared to traditional schools, students in the year-round ones .
| A．perform better and have more learning gains |
| B．have much less time for relaxation every year |
| C．have generally the same number of class days |
| D．hold more classes with more free weeks off |
Which of the following statements is true?
| A．Students from poor families often fall behind after the vacation. |
| B．Year-round schools can solve the problem of the learning gap. |
| C．There are schools in each state following a year-round calendar. |
| D．Nothing can help the students who fall behind after the vacation. |
Why did almost all parents dislike the term “summer school”?
| A．They cherish the children’s rights of freedom very much. |
| B．They are worried about the quality of the “summer school”. |
| C．They want their children to be forced to make up the gap. |
| D．They can’t afford the further study during vacation. |
What would be the best title of this passage?
| A．Opening Summer Camps |
| B．Forbidding Summer Schools |
| C．Spreading Year-Round Education |
| D．Minding the Summer Learning Gap |
I am a psychologist. I first met Timothy, a quiet, overweight elevenyearold boy, when his mother brought him to me to discuss his declining grades. A few minutes with Timothy were enough to confirm that his self-esteem (自尊) and general happiness were falling right along with them.
I asked about Timothy’s typical day. He awoke every morning at six thirty so he could reach his school by eight and arrived home around four thirty each afternoon. He then had a quick snack, followed by either a piano lesson or a lesson with his math tutor. He finished dinner at 7 pm, and then he sat down to do homework for two to three hours. Quickly doing the math in my head, I found that Timothy spent an average of thirteen hours a day at a writing desk.
What if Timothy spent thirteen hours a day at a sewing machine instead of a desk? We would immediately be shocked, because that would be called children being horribly mistreated. Timothy was far from being mistreated, but the mountain of homework he faced daily resulted in a similar consequence — he was being robbed of his childhood. In fact, Timothy had no time to do anything he truly enjoyed, such as playing video games, watching movies, or playing board games with his friends.
Play, however, is a crucial part of healthy child development. It affects children’s creativity, their social skills, and even their brain development. The absence of play, physical exercise, and freefrom social interaction takes a serious toll on many children. It can also cause significant health problems like childhood obesity, sleep problems and depression.
Experts in the field recommend the minutes children spend on their homework should be no more than ten times the number of their grade level. As a fifthgrader, Timothy should have no more than fifty minutes a day of homework (instead of three times that amount). Having an extra two hours an evening to play, relax, or see a friend would soundly benefit any child’s life quality.What did the writer think of Timothy after learning about his typical day__________?
| A．Timothy was very hardworking. |
| B．Timothy was being mistreated. |
| C．Timothy had a heavy burden. |
| D．Timothy was enjoying his childhood. |
Which of the following statements best describes the writer’s opinion________?
| A．Children should be allowed enough time to play. |
| B．Playing board games works better than playing video games. |
| C．The more they play, the more creative children will become. |
| D．The depression caused by homework makes children unwilling to play. |
According to the passage, how long should a thirdgrader spend a day doing homework________?
| A．About ten minutes. | B．No more than twenty minutes. |
| C．No more than thirty minutes. | D．About fifty minutes. |
