【答案】

1B

2B

3C

【解析】

1

由题目可知,材料描述的是我国黑土广布的东北平原,与华北平原相比,发展农业最有利的条件是黑土面积广大,土壤肥沃,故选B。

2

东北地区农业以旱地农业为主,故A正确。由于纬度高、热量不足,农作物熟制是一年一熟,故B错误。主要农作物有小麦、大豆、甜菜,故C正确。粮食产量丰富,商品率高,有“北大仓”称号,故D正确。故选B。

3

目前,该地区除了水土流失以外,还有湿地面积日益减少、生态环境恶化、土地肥力下降和环境污染等问题,湿地面积日益增多有利于农业可持续发展,故选C。

本题考查东北地区农业生产及生态环境的有关知识。

【题目】 A teacher from Ghana has received worldwide praise after people saw a photo showing him teaching students how to use Microsoft Word on a blackboard.

Richard Appiah Akoto teaches computer classes at a middle school in rural Ghana. However, there are no computers at school. To solve the problem, Akoto tries to draw computer screenshots (屏幕截图) onto the blackboard with colored chalks.

He spends about 30 minutes making these drawings. He draws every detail and feature (特征) of the software, including all the tools and the scroll bars (滚动条). To_make_room_for_the_next_class,_these_drawings_will_be_cleaned_when_the_computer_class_is_over. Therefore, Akoto has to draw new screenshots every time.

Akoto has taught computer class for six years and this is not the first time he has taught his students with drawings on the blackboard. He has taught his students how to turn on and off a computer and create a folder (文件夹) in the same way.

Akoto was happy when one of his students got an “A” in the national exam on computer skills last year. He says he loves his students, and this is why he needs to do everything that will make them understand what he is teaching.
