A new study warns that about thirty percent of the world people may not have enough water by the year 2025. A private American organization called Population Action International did the new study. It says more than three hundred and thirty-five million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.

　　PAI researchers Robert Engel says by the year 2025,about three thousand million people lack water. At least 18 more countries are, expected to have serious water problems. The demand for water keeps increasing. Yet the amount of water on the earth stays the same.

　　Mr. Engel says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will increase.

　　The report says lack of water in the future may result in several problems. It may increase health problem. Lack of water often means drinking water is not safe. Mr. Engel says there are problems all over the world be cause of diseases such as cholera（霍乱）that is carried in water.

　　Lack of water also results in more international conflict（冲突）. Countries may have to fight for water in the future. Some countries now get sixty percent of their water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability to improve their economics. This is because new in dustries often need large amounts of water when they are beginning.

Although international students want to dive into American culture, it is easier to stay close to the families．

“Most international students told me that they want to meet and make friends with as many Americans as they can,” said Mark Galloway, Institute for International Studies (IIS) student adviser at State University．

“But in reality, they are comfortable with being around people from their own country, if possible．”

Testing of English as a Foreign Language (TOEFL) is an admission test for international students enrolling in American universities．Galloway said students’ scores decreased when they spend less time with American students．

More than 450 international students are on campus at Murray State University．Thailand, Japan, South Korea, China and Germany are countries with the most students this semester, according to an IIS report．

Wichien Eampromate, Thai Student Association President, said poor English ability and cultural differences make it difficult for Thai students to spend time with Americans．

“We eat different things; we do different kinds of things,” said Eampromate．

On the other hand, Joon-Seong Bae, an exchange student from Korea University, said he tried to avoid hanging around other Koreans．

But it is not easy for him．He said he is less comfortable with Americans because he cannot say everything he wants to say, and not all Americans are patient with his limited English．

“There were two or three Americans and me,” Bae said．“We talked about something．As time went by, I was kind of excluded(排斥在外) because they talked to each other．

While international students venture outside their comfort zones, American students also have the opportunity to be exposed to other cultures．

“I know there are a lot ( of American students) who want to get to know international students,” said Philip Lee, senior from Boonville, Indiana．“They are just uncomfortable．”

Lee said he has learned about life from his international friends, although it is sometimes a challenge．

“ I can’t live a comfortable life all the time,” Lee said．“ I realized there is a great benefit of stepping out of my comfort zone to meet people．”
