【题目】我国各地土地资源类型差别很大,因地制宜对土地进行多样化的开发和利用是我们的基本原则。据此判断,下列地区主要土地利用类型搭配合理的是

A. 青藏高原——林地B. 长江中下游平原——水田

C. 秦岭山区——草地D. 大兴安岭——旱地

【答案】B

【解析】

我国各类土地资源齐全,形成了耕地、林地、草地等多种土地类型,这有利于因地制宜,进行多样化的开发利用。然而,我国各类土地资源在土地资源总量中所占的比重是不同的,其中草地面积较广,占的比重大,而耕地、林地所占比重相对偏小。

我国土地资源的空间分布不平衡,土地生产力的区域差异明显。我国耕地主要分布在东部季风区的平原和盆地地区,其中南方水田为主,北方主要是旱地为主。我国西部耕地面积小,分布零星。我国的天然林地主要分布在东北、西南,东南部山区的林地多为人工林和次生林。西北和华北的大部分地区林地很少。我国草地主要分布在内蒙古的东部、青藏高原的东部与南部。我国难以利用的土地比重较大,例如分布在新疆、内蒙古的干旱荒漠,青藏高原上的高寒荒漠等。故选:B

【题目】Dear Simon,

I am glad to know that you have joined your school reading club. I enjoy reading, too. I want to introduce to you my favorite novel, Charlie and the Chocolate Factory (《查理和巧克力工厂》).

The novel tells the story of a boy named Charlie Bucket and his adventures (冒险经历) in Mr. Wonka's chocolate factory. The Bucket family is very poor. Charlie loves Wonka chocolate bars. But he only receives one chocolate bar a year on his birthday.

One day, Mr. Wonka decides to open up his factory to five lucky children. They can find golden tickets in their Wonka chocolate bars. On his birthday, Charlie's family all hope that his chocolate bar will contain a golden ticket. But sadly, it doesn't. Three days later, Charlie finds a coin on the ground. He buys some chocolate bars with it. To his great surprise, he finds a golden ticket!

Charlie goes to the factory with his grandfather. It is an amazing place. There is even a chocolate river! One by one, the other four children on the tour cause trouble. They are all taken away. Charlie is the only child who doesn't cause any trouble. Mr. Wonka tells him that he wins the contest.

Do you know what Charlie wins? You will find the answer in the novel. Do share your feelings about the story with me when you finish reading it. I'm looking forward to your reply. I hope you will like this novel.

With love,

Carl
