What is the main idea of this paragraph? Over the next four years, you and your classmates will also teach one another. There is a good chance that you will never again live and work in a community with as many different cultures and backgrounds as MIT. You will share your MIT experience with classmates who do not look or talk or think like you, which will prepare you well for global collaborations in your careers. What's more, you do not have to look very hard for new intellectual adventures here. You can take a summer internship (实习期) in a foreign country through the program we call MISTI (MIT International Science and Technology Initiative).
