问题 单项选择题

现实粮食种植规模是指农民自愿种植粮食作物的规模。近五年来江苏省粮食播种面积逐年减少,种植结构调整是主要原因。1999-2001年是江苏省农民大幅调整种植结构时期,三年内全省共减少粮食面积1589万亩,占近五年粮食面积减少总量的82%。2002-2003年江苏省农民继续调整种植结构,但调整幅度趋缓。2002全省粮食种植面积只比2001年减6万亩。2003年粮食播种面积虽比2002年减少335万亩,但其中有相当一部分是因灾绝收而减少的,当年的粮食播种面积不能反映农民实际种植粮食的规模。为此,江苏省取2002-2003年的平均粮食播种面积7157万亩,作为该省现实粮食种植规模。用同样的方法测算,小麦、水稻的播种面积分别为2431万亩、2867万亩。

根据上一题的假设,那么1999年的粮食播种面积是多少万亩()

A.8989

B.9189

C.9089

D.9289

Supermarkets are trying out new computers that make shopping carts more intelligent (具备智能的). They will help shoppers find cups or toilet soap, and keep a record of the bill.

The touch-screen devices (触摸屏装置) are on show at the Food Marketing Institute's exhibition here this week. "These devices are able to create value and get you around the store quicker," said Michael Alexandor, manager of Springboard Retail Networks Inc., which makes a smart cart computer called the Concierge.

Canadian stores will test the Concierge in July. A similar device, IBM's "shopping buddy," has recently been test-marketed at Stop & Shop stores in Massachusetts.

Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.

"The whole model is driven by advertisers' need to get in front of shoppers," said Alexandor. "They're not watching 30-second TV ads anymore."

People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system (系统) that will organize the trip around the store. If you're looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.

The devices also keep a record of what you buy. When you're finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay.

The new computerized shopping assistants don't come cheap. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device.

A.supermarkets    B.shop assistants        C.shopping carts    D.shop managers

A.intelligent shopping carts cost a large sum of money

B.the Concierge is cheaper than the Buddy devices

C.shop assistants with computer knowledge are well paid   

D.average stores prefer the Concierge to the Buddy devices
