來美國前需要知道的冷知識：

1.不要複印教科書或其他書籍，這是違法行為。上學用的教科書非常昂貴，一本平均價格落在100到200美元以上。出版社還會定期進行改版，如果沒有買當期的書，可能會跟不上進度。如果有預算考量，可以考慮上網或向之前上過課的同學購買二手書。如果被發現影印書籍，將會面臨法律處罰，而影印店也有責任。

2.當遇到警察盤查時，應盡量配合，不要立即伸手拿證件。如果不小心被認為拿槍，可能會被警察誤認為威脅，進而導致射殺事件的發生。

3.在紐約，不能公開飲酒，否則會受到罰款。去年至少有上萬民眾因為公然飲酒而被開出罰單。

Cold Facts to Know Before Coming to the United States:

Do not photocopy textbooks or other books, as this is illegal. Textbooks used for school are very expensive, with an average price ranging from $100 to $200 or more per book. Publishers also regularly release new editions, so not having the current book may result in falling behind. If budget is a concern, consider buying second-hand books online or from classmates who have previously taken the class. Being caught photocopying books can lead to legal consequences, and photocopying shops also bear responsibility.

When stopped by police for questioning, try to cooperate as much as possible and avoid reaching for your identification immediately. Accidentally being perceived as reaching for a weapon may lead to police mistakenly shooting you.
