In the United States, 30 percent of the adult（成年人）population has a “weight problem.”. To many people, the cause is clear: We eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were slimmer than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch television.
Several modern studies, moreover, have shown that fatter people don't eat more on average than thinner people. In fact, some investigations (researches), such as a 1970 study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people.
Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts.
The more the men ran, the greater loss of body fat.
The more they ran, the greater their increase in food intake(吸收)。
Thus those who ran the most ate the most, yet lost greatest amount of body fat.
1.What kind of physical problem do many adult Americans have?
A. They are too slim B. They work too hard
C. They are too fat D. They lose too much body fat.
2.Based on the statistics (数据) given in the article, suppose there are 500 adult Americans, about how many of them will have weight problems?
A. 30 B. 50 C. 100 D. 150
3. Is there scientific evidence to support eating too much is the cause of a “weight problem”?
A. Yes, there is plenty of evidence.
B. Of course, there is some evidence to show this is true.
C. There is hardly any scientific evidence to support this.
D. We don't know because the information is not given.
4.In comparison(比较)with the adult American population today, the Americans of 1910____
A. ate more food and had more physical activities
B. ate less food but had more activities
C. ate less food and had less physical exercises
D. had more weight problems

In 1999, twelve percent of public elementary schools in the United States required students to wear uniforms. Just three years later, the amount was almost double that.
A study of six big-city Ohio public schools showed students who were required to wear uniforms had improved graduation, behavior and attendance rates. Academic performance was unchanged.
Some high schools in Texas have also joined in the movement. Yet studies find mixed results from requiring uniforms. And some schools have turned away from such policies.
Supporters believe dressing the same creates a better learning environment and safer schools. The school district in Long Beach, California, was the first in the country to require uniforms in all elementary and middle schools. The example helped build national interest in uniforms as a way to deal with school violence and improve learning.
Findings in Long Beach suggested that the policy resulted in fewer behavior problems and better attendance. But researcher Viktoria, who has looked at those findings, says they were based only on opinions about the effects of uniforms.
She says other steps taken at the same time to improve schools in Long Beach and statewide could have influenced the findings. The district (the area marked by government) increased punishments for misbehavior. And California passed a law to reduce class sizes.
In Florida, for example, researcher Sharon found that uniforms seemed to improve behavior and reduce violence. In Texas, Eloise found fewer discipline problems among students required to wear uniforms, but no effect on attendance.
Sociologist David has studied school uniform policies since1998．He collected the reports in the book. In his own study, he found that reading and mathematics performance dropped after a school in Pennsylvania(宾夕法尼亚州) required uniforms.
Political and community pressures may persuade schools to go to uniforms to improve learning. But David and others believe there is not enough evidence of a direct relationship. In fact, he says requiring uniforms may even increase discipline problems.
67．Which of the following researchers are NOT supporters of school uniform policies?
A．Viktoria and Sharon. B．Sharon and David.
C．Eloise and Sharon. D．Viktoria and David.
68．The underlined word“misbehavior”in the sixth paragraph probably means ________.
A．serious crime B．bad performance
C．absence for class D．action against wearing uniforms
69．What can we infer from the passage?
A．More work is needed to get better information about uniform’s effect.
B．The number of schools requiring uniforms in the U.S. will become less sharply.
C．Wearing uniforms has little to do with behavior and learning.
D．Politicians and communities won’t vote for uniform policies.
70．What’s the main idea of this passage?
A．More and more students are required to wear uniforms in the U.S.
B．Wearing uniforms contributes to good academic performance.
C．Researchers in the U.S. argue for school uniform policies.
D．Evidence for school uniform polices in the U.S. is seen as weak.

About 10 percent of public school students in the United States learn English as a second language. In some states, that number is much higher. About five million students in the country are considered English language learners, or ELLs. Such students are the fast-growing group in the US public schools.
The most commonly first spoken languages among ELLs in America are Spanish, Arabic, Chinese, Haitian Creole and Vietnamese. Speakers of those five languages make up 92 percent of all ELLs included in the report.
English language learners can choose one of several kinds o1 program. There are some programs, in which students are mostly taught in their native language. And there are other programs, which offer students almost all classroom teaching in English. However, These kinds of programs do not always allow students to write and read in their native language.
There are also so-called bilingual programs. These programs offer teaching in two languages-English and another language. Research has shown that English language learners do best in bilingual programs, especially if the second language is their native language.
The lack of high-quality bilingual programs is clear. Nationally, about 83 percent of students complete their high school education. But the graduation rate (比率) among English language learners is far lower 65 percent.
School systems across the country sometimes look for bilingual educators internationally. But education experts say there are ways for states to find and train new teachers in their own areas. This spring, America came up with a list of “grow your own” rules for schools and states to follow. It advised states to offer a series of ways for bilingual teachers. It also suggested training bilingual teachers in their own areas even if they do not have a college degree.
1.What can we learn about English from paragraph 1?
A.It is difficult for most students.
B.It is popular as a second language in American public schools.
C.It is easy for foreign students.
D.It is not welcome by public school students.
2.How many types of programs for English language learners are mentioned in the text?
A.One. B.Two.
C.Three. D.Four.
3.What does the underlined word “bilingual” in paragraph 4 mean?
A.Learning one language. B.Using two languages.
C.National. D.International.
4.Where is the text probably from?
A.An educational magazine. B.A maths paper.
C.A diary. D.a storybook.
