【正确答案】 D

【答案解析】[听力原文]23-25
Speaker: Will people still run their errands in the same way fifty years from now? Will they still go to grocery store for food and to the bank for money? Some experts think that in fifty years, people will run both of these errands and maybe more from their living rooms. It is convenient to do so. What they will have to do is buy home computers without even having to take any course in programming. They will simply talk to their computers, and if it is possible, the computers will talk back to them. By and by, people will do shopping at home. It saves much of their time. For example, a family wants to buy a TV. They will see a picture of the model they want on a video screen and find the store with the most reasonable price. Then they will send a message to that store, and the right amount of money will be taken out of their bank and put into the store's. Many people will run most of their errands electronically. But sometimes, they will still want to go shopping in the old-fashioned way, that is, going from store to store to find a dress they like or a nice gift for their best friend, for it is a kind of enjoyment.

讲话中提到通过电脑购物可以节省时间但不能省钱，所以A项不对。B和C都为干扰选项，不是电脑购物的原因。原文中“It is convenient to do so．”和“It saves much of their time．”两句话都可以证明D为正确选项。

【正确答案】 A

【答案解析】此题考查词义，要根据上下文来判断。原文中“By and by，people will do shopping at home”和“Many people will run their errands electronically．But sometimes，they will still want to go shopping in the old-fashioned way...”等句可以说明A即为正确选项。
