单选题 Listen to the statement and match each option with the right sending method. A—Registered mail B—Recorded delivery C—Express mail
单选题 providing door to door mailing service __________
【正确答案】 C
【答案解析】Taking consideration of your personal requirements, I will introduce three different sending methods to you, that is registered mail, recorded delivery and express mail. Registered mail provides the maximum security. Items you send with registered mail are placed under tight security from the point of mailing to the point of delivery, and insured up to $25,000 against any loss or damage. And you can verify the date and time of delivery and the delivery attempts online, so it is the most expensive one. Contrasting with the registered mail, recorded delivery is a system whereby on payment of a fee in addition to the postage, a certificate of posting is given to the sender at the time of posting and a receipt is signed by the addressee when delivery is made. It differs from the registration service in that the tracking of recorded delivery items at each processing stage is not provided as in the case of registered items. This service will satisfy the demand of those senders who need a more economical way to send important documents or other mail of little or no monetary value but still require proof of posting and proof of delivery. The last one is express mail. Express mail service is a fast delivery service operated among the member countries of Universal Postal Union, providing the efficient door to door mailing service for customers.
