【题目】读等高线地形图,回答下列问题.

(1)图中,甲、乙两山顶间的图上距离为2厘米,实际直线距离为________千米.甲山在乙山的_________方向.

(2)甲山比乙山海拔低_________米.

(3)一个野外探险小队决定在B点和H点两处选择露营地______处合理,原因为______________

(4)A处地形为________,G处地形为_______。图中DC线和EF线地形,______ 条线可能存在河流.

(5)若图中丙地的气温是21℃,根据一般规律,则乙山的气温应是________℃。(取整数)

(6)右图为丙地气温和降水量年变化图,请问丙地的气候类型为________

【答案】6 东北 170 H H处是缓坡 鞍部 陡崖 EF 14 亚热带季风气候

【解析】

(1)由比例尺可知,图中甲、乙两山顶间的图上距离为2厘米,实际直线距离为6千米;甲山是位于乙山的东北方向。

(2)由图可知,甲山的海拔是1150米,乙山的海拔是1320米,所以甲山比乙山低170米。

(3)一个野外探险小队决定在B点和H点两处的H处选择露营地,因为H处等高线稀疏是缓坡。

(4)图中A处地形是鞍部,G处地形是陡崖,图中DC线和EF线地形中,EF线可能存在河流,这里是山谷。

(5)若图中丙地的气温是21℃,根据一般规律,则乙山的气温应是14℃。

(6)由图可知,丙处是夏季高温多雨、冬季温和少雨的亚热带季风气候。

【题目】There are two ways of driving in the world: if the driver's seat is on the left and cars travel on the right side of the road, it is called "left-hand driving", as it is in China, while the other way of driving is called "right-hand driving", as it is in Britain. Nowadays, around 65% of the world's population drives on the right of the road, while the rest is used to driving on the left.

Though no one knows the exact reasons, it seems likely that people in ancient times travelled on the left of the road. Roman coins show pictures of horsemen passing on each other's right. And right-hand people generally got on a horse from the animal's left. Obviously, it's safer to do this at the left side of the road, and it makes sense(行得通)for the horse to be ridden on the left.

A change happened in the late 1700s. When Napoleon(拿破仑)conquered(攻占)nations, he forced them to travel on the right side of the road, which spread left-hand driving throughout Europe. However, Britain still stuck with the right-hand driving rule and countries which were part of the British Empire were made to follow. This is why India, Australia and the former British colonies(前英国殖民地)in Africa continue to drive on the left. One exception(例外)is Egypt, as that country was defeated(打败)by Napoleon before becoming part of the British Empire.

Some countries changed sides until modern times. Sweden only moved to driving on the right in 1967 and Iceland changed the following year. Ghana changed sides in 1974. On September 7, 2009, Samoa became the third country ever to change from left-to-right-hand driving for the reason that it made it easier to import(进口) cheap cars from right-hand driving Japan, Australia and New Zealand.

So if you want to travel to another country or go on business, make sure you know whether it is left-or right-hand driving to avoid unnecessary troubles.

D. Napoleon helped with the spread of left-hand driving.

3What is the writer's purpose for writing this passage?

A. To explain the advantages of the two ways of driving.

B. To introduce the development of the two ways of driving.

C. To complain about the change of the two ways of driving.

D. To compare the differences of the two ways of driving.
