题目内容

【题目】下图是沿我国境内某一经线的地形剖面、气候统计图。读图，完成下题。

【1】下列有关图中山岭的说法正确的是

A.是我国第二级阶梯和第三级阶梯的分界线

B.该山脉大体呈南北走向

C.与400毫米等降水量线大致吻合

D.是亚热带和暖温带、湿润区和半湿润区的分界线

【2】图中降水最多的地点，其海拔约为

A．900m B．1500m C．2000m D．3000m

【答案】

【1】D

【2】B

【解析】

试题分析：

【1】图示山地海拔超过3000米，不可能是我国第二级阶梯和第三级阶梯的分界线，A错；南坡降水远多于北坡，南坡为迎风坡，该山可能是东西走向，B错；该山7月山麓地带的降水大于500MM，不可能与400毫米等降水量线大致吻合，C错；该山夏季高温多雨，降水量南多北少,南坡降水大于800MM，北坡降水400-800间，可判断是秦岭山，是我国亚热带和暖温带、湿润区和半湿润区的分界线。选D正确。

【2】图中降水量最多是南坡1500M左右，降水是1250MM。选B正确。

【题目】C

The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of certain animals and birds, and even disturbs the world’s ecological balance.

On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other species(物种)that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many species are quickly dying out.

On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests’ plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world’s groundwater.

Both locally and globally, the continued spread of full-sun coffee plantations(种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world’s climate, and studies show that the loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的)soil conditions.

It is obvious that the way much coffee is grown affects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.

【1】What can we learn about full-sun coffee production from Paragraph 4?

A. It limits the spread of new growing techniques.

B. It leads to air pollution and global warming.

C. It slows down the loss of shade trees.

D. It improves local soil conditions.
