Очень нужно помогите пожалуйста!!!
1. CMSU is a state University. 2. More than 11,000 students are currently enrolled in it. 3. 10 % of these students are international students from all over the world: China, Indonesia, Germany, Sweden, France, Russia, Taiwan, Thailand and many other countries. 4. The age of the students varies from 18 to 65. 5. You can imagine how much diversity we have here.
6. There are many different goals that drive students to Central University. 7. For American men and women, there is one primary goal — to get a quality education in order to seek a well-paid job. 8. For many international students, this is not the only reason to seek an education at Central. 9. Many international students are driven by the desire to learn English in order to work internationally. 10. As it is known, the demand for people with an American diploma is very high in many countries. 11. When I went back home for vacation, there was an ad in the very first newspaper which I read in St. Petersburg. 12. In the article it was stated that an international company needed a person with an American diploma, computer knowledge, and good skills in English. 13. The salary was really good. 14. As you see, this reason is pretty self-explanatory why many international students want to study in the US.
