到华盛顿以后，常有朋友来信问我：在美国过日子，最基本的要求是什么？我说，丙个三大件：一是语言、学位、技能;二是汽车、房子、计算机。前者是软件，后者是硬件。三大硬件车为首美国的居住区大多远离闹市，以安静和高雅为时尚。人们出行，不论是上班还是购物，一般都是开车 After coming to Washington, a friend of mine often wrote to ask me: What are the basic requirements for living in the United States? I said that C has three major items: First, language, degree, and skills; second, cars, houses, and computers. The former is software and the latter is hardware. The three major hardware vehicles led the United States residential areas are mostly away from downtown, with a quiet and elegant fashion. People travel, whether they are at work or shopping, they usually drive.
