Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 to 45. Most banks in the US open at 9:00 or 10:00 and close between 3:00 and 5:00, but stay open later on Fridays, and some banks have longer hours in order to attract customers on this day. What’s the best way to carry money safely while you are traveling There are three possibilities-personal checks from your country, travelers checks and credit cards. Some Ame-rican banks accept foreign checks such as Eurocheques (欧洲货币支票)；the problem is that only those banks that are used to dealing with foreigners will know what Eurocheques are. It may be more convenient to carry travelers checks, which are insured against loss. They should be in dollars, because only a few banks do much business in foreign currencies. If your checks aren’t in dollars, it may take you a long time to find a bank that will exchange them. You can use travelers checks almost anywhere. If you run out of them, you can buy more at most banks. Their service charge will vary, though, so ask what it is before you buy your checks. Americans would say the best way to carry money is to have a credit card. Credit cards can be canceled if they are lost or stolen. And because they are widely accepted in the US, it is easy to use them to pay all kinds of bills. Of course, you can’t get along without cash, but you don’t need to carry much with you.
