【题目】家住昆明的李媛和太原的中学生赵梅是微信好友。据此完成下面小题。

1昆明的李媛想了解太原在中国的位置,她应该查看的地图是

A.中国地形图B.中国政区图

C.山西省交通图D.山西省政区图

2李媛量得昆明到太原的图上距离是4厘米,又知道昆明到太原的实地距离约为2000千米,那这幅图的比例尺是

A.1∶10000B.1∶50000000C.1∶5000D.1∶40000

【答案】

1B

2B

【解析】

根据地图是学习地理必不可少的工具。人们从地图上可以直接获得大量有用的地理信息。我们要掌握使用地图的方法,在日常生活中养成经常读图、用图和收集地图的好习惯;比例尺是表示图上距离比实地距离缩小的程度,进行分析解答。

1在庞大的地图家族中,有自然地图和社会经济地图。自然地图包括地形图、气候图、水文图、植被图等,社会经济地图包括工业图、农业图、商业图、交通图、人口分布图等。日常生活中,我们应根据实际需要选择合适的地图;故昆明的李媛想了解太原在中国的位置,她应该查看的地图是中国政区图。故选:B

2比例尺是表示图上距离比实地距离缩小的程度;根据比例尺公式:比例尺=图上距离/实地距离;已知图上距离为4厘米,实地距离约为2000千米,那这幅图的比例尺是4:2000000001:50000000。故选:B

考查地图的运用及比例尺的计算。

【题目】Today is the Earth Day. Our reporter Nick Ford interviewed several people in the street. This is what they told him:

9:24 Miss Mayfield, a young teacher

I try to tell my students the importance of our relations with wild animals. I take them to zoos and forests, and I avoid using materials that come from wild animals, for example, ivory, which comes from elephants. I don’t wear things made of fur, and I even avoid buying leather shoes. Wool is okay, though-the sheep don’t get hurt!

10:03 Mr. Perdue, a businessman

I don’t use my car for short journeys. I walk or go by bike. It’s good for my health, and it doesn’t pollute the air.

10:30 Tom Pitt, a 14-year-old student

I only buy writing paper and notebooks made from recycled paper. And when I buy something made of wood, like a wooden table, I’ll make sure that the wood comes from a forest where they plant new trees.

11:01 Mr. White, an artist

I’m an artist, and I enjoy recycled art. They are things made out of rubbish-like this model plane made from old containers. In fact, I hate throwing things away. I even keep my old woolen clothes and cotton handkerchiefs and use them for cleaning.

11:35 Ms. Nelson, a policeman

I’m careful not to waste electricity. For example, I always turn the lights off when I leave a room. And I don’t have the TV on when I’m not watching it.

12:00 Mr. Parks, a doctor

I take my empty bottles, jars, and anything else made of glass to the recycling center every week. I try not to buy plastic bottles because you can’t recycle most kinds of plastic.

【题目】阅读短文,根据所读内容在文章后表格中的空格里填人一个最恰当的单词。

We dislike too hot days. Luckily, we have air conditioners and fridges. How did Chinese people stay cool in the hot season before they have air conditioners and fridges?

The most common way Chinese people in the past kept cool was to use fans. Many fans had poems or drawings on them.

Beginning in the Sui dynasty(朝代), Chinese people started to use porcelain pillows(瓷枕). These pillows felt cool, so people could sleep well on them.

People in old times didn't have fridges to make ice. Instead, they collected ice in winter and kept it underground, sometimes in wells(井). When summer came, they got the ice out and put it in their living rooms to cool them down.

Rich people and members of the king family had more expensive ways to keep cool. As early as the Han dynasty, some people used a tool(工具) like modern electrical fans. It was made of a wheel(轮子) and some fan blades(叶片). A person would pull a rope to make the wheel spin(转) and then the blades would spin around fast.

In the Tang dynasty, people found a way to make their whole house cool. They built their houses next to the water, used some machines to carry water to the top of the house, and made it flow down from the eaves(屋檐). This man-made waterfall brought cool air into the house.
