题干二、阅读理解：阅读下面的短文，根据文章内容进行判断，正确为“T”，错误为“F”。 I Am a Courier I am a courier. Many people today are glad to see us, because they expect to receive what they have bought on the Internet. When I see their eager faces, I feel that my job is valuable. I am proud of my job. Why did I choose to be a courier? The first benefit is, I think, couriers can usually deliver an item faster than it would have taken if sent by other means. For example, a person may need to send a document to someone else. He could do this by sending it through the mail. If the two parties are in the same city, this transaction is likely to take at least one day. Couriers, however, usually can make it happen within hours. Secondly, couriers generally offer a receipt for the delivery and that can make their clients feel more secure. Postal services generally are not as efficient in this regard. Even text messages and e-mails may not be comparable. In many cases, without delivery confirmation, the sender knows that something was sent, but there is no confirmation as to whether it was received or when it was received. Most importantly, the Internet has changed people’s shopping habits. More and more people tend to shop on the Internet. The goods bought on the Internet have to be delivered by couriers. So a courier can make more money if he wants to work longer hours. That’s why I have chosen to work as a courier. Well, that’s about my job. Time is money. I have to send packages to the next place now. Talk to you later. 1. People are glad to see couriers because they can bring people good luck.回答TF正确获得10.00分中的10.00分 2.
