题目分析:本题组主要考查我国北方地区的气候特点、主要的工业基地和东北地区的民居与气候的关系。

(1)据图分析,济南的春季降水少;气温回升快,蒸发旺盛;正值冬小麦返青,农田需水量大。

(2)据图可知,东北地区有我国最大的平原东北平原,土壤肥沃,平原面积广阔;土地集中连片,适于机械化耕作。主要的气候类型为温带季风气候,雨热同期,有利于农作物的生长。

(3)据图可知,两个工业基地附近的煤、石油等矿产资源丰富;人口密集,故劳动力资源丰富;都濒临海洋,与铁路与海港相通,水陆交通便利;工业基础好,科技水平高。

(4)据图分析,延吉积雪厚度高于长春。主要原因是其位于山脉迎风坡且离海较近。

(5)东北地区冬季降雪较多,坡度大,让雪容易滚下,防止积雪压坏房子;东北地区冬季寒冷,大风天气多,墙体厚,窗户小是为了保温。 (只要意思相近即可)

Bill Gates was born on October 28th, 1955. He and his two sisters grew up in Seattle. Their father, William H. Gates II, was a Seattle lawyer. Mary Gates, their late mother, was a school teacher.

Gates attended public elementary school before moving on to the private Lakeside School in North Seattle. It was at Lakeside that Gates began his career in personal computer soft  ware, programming computers at age 13.

In 1973, Gates entered Harvard University as a freshman, where he lived down the hall from Steve Ballmer, who is now Microsoft's president. While at Harvard, Gates developed a version (版本) of the programming language BASIC for the first microcomputer---the MITS Astair. In his junior year, Gates dropped out of Harvard to devote his energies full-time to Microsoft, a company he had started in 1975 with his boyhood friend Paul Allen. Guided by a belief that the personal computer would be a valuable tool on every office desk-top and in every home, they began developing software for personal computers.

Gates' foresight has led to the success of Microsoft and the software industry. He plays an important role in the technical development of new products. Much of his time is devoted to meeting with customers and staying in touch with Microsoft employees around the world through e-mail.

In the dozen years since Microsoft went public, Gates has donated more than $ 800 million to charities, including $ 200 million to the Gates Library Foundation to help libraries in North America make use of new technologies and the Information Age.
