The Mississippi is the major river system in the United States. The Yangtze is China’s longest river.
Although a world apart, the two waterways share conservation concerns that provide a cultural bridge between students in the United States and China, as well as from around the world.
The Mississippi flows almost 3,800 kilometers from a small lake in Minnesota, gathering the waters of 250 other rivers and streams before reaching the Gulf of Mexico.
In mid-May, as spring flowers began to open, about 41 students from a dozen colleges, mostly in the Midwest, explored a section of the river in Wisconsin and Iowa, to learn about the environment, and each other.
The students, from the U.S., China and around the world, came to join the River Spirit Exchange program.
The cross-cultural educational experience - set up by the University of Wisconsin, Madison-based Environment and Public Health Network for Chinese Students - focuses on the Mississippi and China’s longest river, the Yangtze.
This three day get-together featured story-telling, hiking, camping and canoeing, all part of a larger lesson about conservation projects that can be used on both the Yangtze and Mississippi.
While the students learned about the problems challenging the Mississippi and Yangtze, Jeb Barzen, a wildlife biologist, explained they should also learn about the importance of bridging each other’s culture.
The president of the Environment and Public Health Network for Chinese Students, Xiaojun Lu, said the Mississippi and Yangtze Rivers are uniting these students from opposite ends of the earth.
Organizers say the success and spirit of this first gathering of students will lead to other trips, including one down the Yangtze.

An increase in students applying to study economics (经济学) at university is being attributed to （归因于）the global economic crisis (危机) awakening a public thirst for knowledge about how the financial system works.  
Applications for degree courses beginning this autumn were up by 15% this January, according to UCAS, the Universities and Colleges Admissions Service. A spokesman for the Royal Economic Society said applications to do economics at A-level were also up.  
Professor John Beath, the president of the society and a leading lecture at St Andrews University, said his first-year lectures which are open to students from all departments—were drawing crowds of 400, rather than the usual 250.  
“There are a large number of students who are not economics majors, who would like to learn something about it. One of the things I have done this year is to relate my teaching to contemporary events in a way that one hasn’t traditionally done. ” He added.   
University applications rose 70% last year. But there were rises above average in several subjects. Nursing saw a 15% jump, with people’s renewed interest in careers in the pubic sector（部门）, which are seen as more secure in economic crisis.  
A recent study showed almost two thirds of parents believed schools should do more to teach pupils about financial matters, and almost half said their children had asked them what was going on, although a minority of parents felt they did not understand it themselves well enough to explain.  
Zack Hocking, the head of Child Trust Funds, said: “It’s possible that one good thing to arise from the downturn will be a generation that’s financially wiser and better equipped (使…有能力) to manage their money through times of economic uncertainty.”

A study led by Professor Mark Weiser of Tel Aviv University and the Sheba Medical Center at Tel Hashomer Hospital has determined that young men who smoke are likely to have lower IQs than their non-smoking peers (同龄人). Tracking 18-to 21-year-old men enlisted in the Israeli army in the largest ever study of its kind, he has been able to demonstrate an important connection between the number of cigarettes young males smoke and their IQ.

The average IQ for a non-smoker was about 101, while the smokers’ average was more than seven IQ points lower, at about 94, the study determined. The IQs of young men who smoked more than a pack a day were lower still, at about 90. An IQ score in a healthy population of such young men, with no mental disorders(心理疾病), falls within the range of 84 to 116.

An addiction that doesn’t discriminate(歧视)

“In the health profession, we’ve generally thought that smokers are most likely the kind of people who have grown up in difficult neighborhoods, or who’ve been given less education at good schools,” says Weiser, whose study was reported in a recent version of the journal, Addiction, “But because our study included subjects with various socio-economic backgrounds, we’ve been able to rule out socio-economics as a major factor. The government might want to rethink how it arranges its educational resources on smoking.

Making the results more significant, the study also measured effects in twin brothers. In the case where one twin smoked, the non-smoking twin registered a higher IQ on average.

Although a lower IQ may suggest a greater risk for smoking addiction, the representing data on IQ and smoking found that most of the smokers investigated in the study had IQs within the average range, nevertheless.

In the study, researchers took data from more than 20,000 men before, during and after their time in the military. All men in the study were considered in good health, since pre-screening(筛选的)measures for suitability in the army had already been taken. The researchers found that around 28 percent of their samples smoked one or more cigarettes a day, 3 percent considered themselves ex-smokers, and 68 percent said they never smoked.

“People on the lower end of the average IQ tend to display poorer overall decision-making skills when it comes to their health,” says Weiser. He adds that his finding can help address serious concern among heath counsellors at grade and high schools.

1.The study led by Professor Mark Weiser shows that            .

2.According to the passage, a smoking man’s IQ is most likely to be            .

3.What can be learned from the passage?

4.What is the meaning of the underlined part “An addiction that doesn’t discriminate”?
