(1) Living with Americans. For convenience and saving money, don't be roommates with China people. If nothing else, just for your better spoken English, you will have more opportunities to talk with Americans and understand their culture. It is difficult to make friends with American classmates just by taking classes.

(2) Opening an account in a bank, and opening two accounts at the same time, with no management fee and no minimum deposit requirements. There is not much money, just open a checking account, but there is no interest at ordinary times. If the school is in a big international bank such as Citibank or HSBC, choose this kind of bank, which is convenient to use in both China and the United States, and let the family allocate funds online or to the family. If the school doesn't have such a big bank, you can open an account directly online. Moreover, the interest rate of Citibank's electronic savings account is above 5%, which is quite cost-effective.

(3) If you want to apply for a credit card, you'd better bring a domestic credit card. When you apply for a credit card from a bank or credit card company, show your domestic credit card, indicating that you need an American credit card for convenience. If your domestic credit card is visa, Master, American Express, Bank of America or credit card company can easily approve you. Otherwise, you will have to wait a year or two before you can apply for an American credit card.

1. Matters needing attention for private use of public property

Unless it is related to research or teaching assistants, don't use school stationery envelopes to write personal letters or cover letters, don't secretly use off-duty hours or make long-distance phone calls to chat with relatives and friends at night or weekends, don't use the school copier to copy materials related to study, and don't use it to copy the newsletter of homecoming. Don't be greedy and cheap. If you are found, you will regret it too late.

2. Don't call black people "Negro"

Negro means "black" in English. Especially a black man sold from Africa to the United States as a slave; So don't call black people "Negro" in America, especially when talking to white people. Otherwise, the black man will feel your contempt for him; When it comes to black people, it is best to use the word "black", and black people will accept this title frankly.

Modesty is not a virtue.

China regards modesty as a virtue, while Americans regard modesty as a synonym for hypocrisy. If a fluent English speaker apologizes that he doesn't speak English well and then speaks fluent English, Americans will think that he lied and is a hypocritical person. Therefore, when dealing with the United States, you should boldly say your abilities, one is one, ten is ten, and you don't have to be modest and polite, otherwise it will be counterproductive.

4. The meaning of common gestures

Americans should introduce themselves with their fingertips. If we refer to our breasts according to our own habits, they will often feel puzzled and unable to understand. When calling someone over, our habit is to wave, which is "goodbye" in the eyes of Americans; They point their fingers at themselves and greet people, and then gently shake them with their middle and index fingers two or three times. Americans have many gesture habits, such as using the index finger and thumb to form a circle, and the other three fingers reaching up to make an "OK" gesture, indicating "good" and "agreement".

Never cheat in an exam.

Don't cheat in exams, especially in after-school exams or final reports. Never copy. American universities attach importance to the honor system, so don't take chances. If it is discovered, it will be difficult to clean up the stain, and it will be easy to follow the professor's letter of introduction in the future. It's important for finding a job and the future.

6. Curiosity really kills cats.

If you go to the professor's office to discuss things, don't scan the papers on the professor's desk with curious eyes. Don't rummage through the letters or official documents in the professor's mailbox in the department office. Please don't openly use electric cookers to cook and steam vegetables in graduate students' research rooms or laboratories. If you use the refrigerator in the laboratory to temporarily store sandwiches, it is ok to heat the water, but it must not be used as a kitchen.

7. Improve English reading, writing and conversation skills.

It goes without saying that it is important to improve your English writing and speaking skills, such as going to work in the United States after graduation. At the very least, you should write your graduation thesis well and answer questions fluently in the oral exam. Many professors admit that they are unlucky and often spend a lot of time reviewing English instead of changing the content of their papers. Sometimes the professor simply throws the paper back to the students for rewriting, which makes both sides have a lot of misunderstandings and is very unpleasant. The students think that the professor is deliberately making things difficult and wants to keep the students in school. Many international students simply live with China in the small circle of China City. They don't have enough contact with American graduate students or locals, so it is more difficult to improve and use English.
