单项选择题

The number of international students at colleges and universities in the United States has increased continually for fifth year.
The Institute of International Education in New York released its annual "Open Doors" report this week. It says a record ol more than 720,000 students from other countries were studying in America during the last school year. The number was 5% higher than the year before and almost one-third higher than ten years ago.
There were big increases from China, Saudi Arabia, Vietnam, Iran and Venezuela. Almost 22% of international students were Chinese, with increases especially at the undergraduate level. Together, ahnost half of all international students came from China, India and South Korea.
Peggy Binmenthal at the institute says that Chinese students are now studying throughout the United States. Twenty years ago, students from China only knew of a handful of the US institutions, but now they are admitted into the US community colleges, small liberal arts institutions, and research universities—really spread across the US. Ms. Bhimenthal suggests that one reason for the increase is a lack of space in Chinese colleges for everyone who wants an education. She says students and their parents are also looking for a different educational experience.
