A few ways Greyhound can make your next trip even easier

    Tickets By Mail. Avoid lining up altogether, by purchasing your tickets in advance, and having them delivered right to your mailbox. Just call Greyhound at least ten days before your departure (1-800-231-2222).
    Prepaid Tickets. It’s easy to purchase a ticket for a friend or family member no matter how far away they may be. Just call or go to your nearest Greyhound terminal (车站) and ask for details on how to buy a prepaid ticket.
    Ticketing Requirement. Greyhound now requires that all tickets have travel dates fixed at the time of purchase. Children under two years of age travel free with an adult who has a ticket.
    If your destination (目的地) is to Canada or Mexico. Passengers traveling to Canada or Mexico must have the proper travel documents. U. S., Canadian or Mexican citizens should have a birth certificate, passport or naturalization (入籍）paper. If you are not a citizen of the U. S., Canada or Mexico, a passport is required. In certain cases a visa may be required as well. These documents will be necessary and may be checked at, or before, boarding a bus departing for Canada or Mexico.

    People who work night shifts are constantly fighting against an “internal clock” in their bodies. Quite often the clock tells them to sleep when their job requires them to remain fully awake. It’s no wonder that more accidents happen during night shifts than at any other time. Light therapy (光照治疗法）with a bright light box can help night-shift workers adjust their internal clock. However, many doctors recommend careful planning to help improve sleep patterns. For example, night-shift workers often find it difficult to sleep in the morning when they get off work because the body’s natural rhythm (节律）fights back, no matter how tired they are. Some experts recommend that night-shift workers schedule two smaller sleep periods—one in the morning after work, and another longer one in the afternoon, closer to when the body would naturally need to sleep. It’s also helpful to ask friends and family to cooperate by avoiding visits and phone calls during the times when you are sleeping.

Dear Sirs,
    I know that your company has a reputation (声誉) for quality products and fairness toward its customers. Therefore, I’m writing to ask for replacement for a lawn mower (割草机)
    I bought the mower about half a year ago at the Watchung Discount Center, Watchung, Nebraska. I’m enclosing a copy of a receipt for the mower.
    A month after I bought the lawn mower, the engine failed, and it was repaired under warranty (保修期). So far, I have had the engine repaired four times.
    Now the engine has broken down again.
    I have already spent more than $ 300 on repairs, and I am beginning to seriously question the quality of your mowers.
    I am requesting that you replace this mower with a new one.
    I hope that you will live up to your reputation of the good customer service that has made your business successful.

Faithfully,
Rod Green

Dear Sirs,
    For the past 8 years I have been a statistician (统计员）in the Research Unit of Baron & Smallwood Ltd. I am now looking for a change of employment which would broaden my experience. A large and well-known organization such as yours might be able to use my services.
    I am 31 years old and in excellent health. I majored in advertising at London University and I am particularly interested in work involving statistics (统计).
    Although I have had no experience in market research, I am familiar with the methods used for recording buying habits and trends. I hope that you will invite me for an interview. I could then give you further information.
    I am looking forward to hearing from you soon.

Yours faithfully,
                                                                                           Mike Smith

    I am writing to confirm our telephone conversation of Thursday, the 7th, about our visit to your company. Next Monday, December 11, will be fine for us and we hope that it will suit you, too. My secretary, Miss Mary Brown, and Sales Manager, Mr. Zhang Ming, will be coming in the morning. It’s unfortunate that I will not be able to go with them.
    Thanks again for giving us this opportunity to visit with you.
