【題目】家住昆明的李媛和太原的中學(xué)生趙梅是微信好友。據(jù)此完成下面小題。

【1】昆明的李媛想了解太原在中國的位置，她應(yīng)該查看的地圖是

A.中國地形圖B.中國政區(qū)圖

C.山西省交通圖D.山西省政區(qū)圖

【2】李媛量得昆明到太原的圖上距離是4厘米，又知道昆明到太原的實地距離約為2000千米，那這幅圖的比例尺是

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

【答案】

【1】B

【2】B

【解析】

根據(jù)地圖是學(xué)習(xí)地理必不可少的工具。人們從地圖上可以直接獲得大量有用的地理信息。我們要掌握使用地圖的方法，在日常生活中養(yǎng)成經(jīng)常讀圖、用圖和收集地圖的好習(xí)慣；比例尺是表示圖上距離比實地距離縮小的程度，進行分析解答。

【1】在龐大的地圖家族中，有自然地圖和社會經(jīng)濟地圖。自然地圖包括地形圖、氣候圖、水文圖、植被圖等，社會經(jīng)濟地圖包括工業(yè)圖、農(nóng)業(yè)圖、商業(yè)圖、交通圖、人口分布圖等。日常生活中，我們應(yīng)根據(jù)實際需要選擇合適的地圖；故昆明的李媛想了解太原在中國的位置，她應(yīng)該查看的地圖是中國政區(qū)圖。故選：B。

【2】比例尺是表示圖上距離比實地距離縮小的程度；根據(jù)比例尺公式：比例尺＝圖上距離/實地距離；已知圖上距離為4厘米，實地距離約為2000千米，那這幅圖的比例尺是4:200000000＝1:50000000。故選：B。

考查地圖的運用及比例尺的計算。

【題目】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.

【題目】閱讀短文，根據(jù)所讀內(nèi)容在文章后表格中的空格里填人一個最恰當(dāng)?shù)膯卧~。

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(輪子) and some fan blades(葉片). A person would pull a rope to make the wheel spin(轉(zhuǎn)) 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.
