Thanks to rising agricultural productivity ,lean years are rarer all over the globe .According to the UN ,the number of people short of food fell from 920 m in 1980 to 799 m 20 years later ,even though the world's population increased by 1.6 billion over the period .This is mostly a cause for celebration .Mankind has won what was ,for most of his time on this planet ,his biggest battle：to ensure that he and his offspring had enough to eat.

Will public-health warnings ,combined with media pressure ,persuade people to get thinner ,just as they ?finally? put them off tobacco? Possibly .In the rich world ,sales of healthier foods are booming and new figures suggest that over the past year Americans got very slightly thinner for the first time in recorded history .But even if Americans are losing a few ounces ,it will be many years before the country solves the health problems caused by half a century's dining to overload .And ,everywhere else in the world ,people are still piling on the pounds .That's why there is now an agreement among doctors that governments should do something to stop them.?

Joseph Goldberger was a doctor for the Unite States Public Health Service. In 1912, he began to study a disease that was killing thousands of people in the South. The disease was pellagra(烟酸缺乏病).
Doctor Goldberger traveled to the state of Mississippi where many people had pellagra. He studied the patients and their families. Most of the people were poor. The doctor came to believe that the disease was not passed from one person to another, but instead had something to do with food.
He received agreement from state officials to test this idea at a prison(监狱). Prisoners were offered pardons if they took part. One group of prisoners received their usual food, mostly corn. A second group ate meat, fresh vegetables and milk. Members of the first group developed pellagra. The second group did not.
But some experts refused to accept that poor food caused pellagra. They thought there were other causes.
So Doctor Goldberger put blood(血液) from a person with pellagra into his own body. He even took pills that had blood from pellagra patients. An assistant also took part in the experiments. So did Doctor Goldberger’s wife. None of them got sick. Later, the doctor discovered that a bit of dried brewer’s yeast(酿酒的酵母) each day could prevent pellagra.
Joseph Goldberger died of cancer in 1929. He was 55 years old. Several years later, researchers discovered the true cause of pellagra: having little of the vitamin B.

The legal age for drinking alcohol in the Unite States is twenty-one. Underage drinking is a crime but also a common part of college social life. This week in our Foreign Student Series, we look at alcohol rules at American colleges and universities. These rules differ from school to school, but many schools have been moving to strengthen their rules.
The United States has more than 17,000,000 students in higher education. Each year, 1700 of them die from alcohol-related road crashes and other injuries. 600,000 more are injured while under the influence of alcohol. And almost 700,000 are attacked by another drunken.
One behavior that college officials are trying to prevent is too much drink. Some researchers have found that students who think binge drinking(狂饮) is normal often think extremely how much other students really drink. A person can die of alcohol poisoning. At Oklahoma University, a nineteen-year-old student died from drinking heavily at a party in 2005.
Now alcohol is banned from all sorority houses(联谊会会馆) and university housing. Student organizations can serve alcohol at events but only on Friday and Saturday nights. Other new requirements include an alcohol education program that first-year students take online.
The rules govern behavior on campus(大学校园)and off. With a first violation(违犯)，students pay seventy-five dollars and their parents are told. They must also take an alcohol education class. For a second “strike”, they have to pay one hundred fifty dollars. A third strike means that they have to be suspended school for at least one semester.
Since 2005,363 students have had a first strike. 30 have had a second strike-and only one hasn’t allowed to go to school for one semester. The president at Oklahoma tells us the aim is not just to punish but to change the behavior and culture at the university.
【小题1】The first paragraph mainly tells us that .

A．the legal age at the lowest for drinking alcohol is 21

B．many colleges consider drinking alcohol to be a crime

C．drinking alcohol is a necessary and popular campus culture

D．American colleges and universities have their own alcohol rules

【小题2】Every year the number of the students who die or are injured because of alcohol in the USA adds up to about .

【小题3】If a student has a third strike, he or she should .

A．have to stop going to school for a time.

B．be removed to another school

C．be locked at home for a period.

D．be forced to leave school forever.

【小题4】Which of the following is TRUE?

A．College students are not allowed to drink alcohol at any time.

B．If students take an alcohol program online, they can drink alcohol.

C．Students having a first strike only receive punishment of fine.

D．Students with a second strike pay twice as much as students with a first strike.

【小题5】From the last paragraph we can infer that .

A．alcohol rules have no effect on college students

B．drinking alcohol remains a serious problem

C．alcohol rules aim to change the behavior and culture at the university

D．the number of students drinking alcohol is dropping in one way

American public education has changed in recent years. One change is that increasing numbers of American parents and teachers are starting independent public schools called charter schools.

In 1991, there were no charter schools in the Unite States. Today, more than 2300 charter schools operate in 34 states and the District of Columbia. 575000 students attend these schools. The students are from 5 years of age through 18 or older.

A charter school is created by groups of parents, teachers and community members. It is similar in some ways to a traditional public school. It receives tax money to operate a number of students. The charter school must prove to local or state governments that its students are learning. These governments provide the school with the agreement, or charter that permits it to operate.

Unlike a traditional public school, however, the charter school does not have to obey most laws governing public schools. Local, state or federal governments cannot tell it what to teach.

Each school can choose its own goals and decide the ways it wants to reach those goals. Class sizes are usually smaller than in many traditional public schools. Many students and parents say teachers in charter schools can be more creative.

However, state education agencies, local education-governing committees and unions often oppose charter schools. They say these schools may receive money badly needed by traditional public schools. Experts say some charter schools are doing well while others are struggling.

Congress provided 200 million dollars for establishing charter schools in the 2006 federal budget. But, often the schools say they lack enough money for programs. Many also lack needed space. District officials say they have provided 14 former school buildings for charter education. Yet charter school supporters say officials should try harder to find more space.
