【題目】下圖為我國(guó)東南某地區(qū)等坡度線（地表坡度值相等的點(diǎn)連成的線）圖，圖中數(shù)字代表坡度（坡面與水平面的夾角）。讀圖完成下列問(wèn)題。

【1】圖中河流，流速最快的河段是（ ）

A．甲 B．乙

C．丙 D．丁

【2】圖示區(qū)域（ ）

A．P地坡度最陡

B．河流從東北流向西南

C．適宜發(fā)展果林業(yè)

D．Q地位于背風(fēng)坡，土壤水分條件差

【答案】

【1】A

【2】C

【解析】

試題分析：

【1】圖中數(shù)值越大表示坡度越大，而流速與坡度有關(guān)，線條越密集表示坡度變化越大，不是坡度越大，注意與等高線疏密的不同。由圖示等坡度線可以看出：圖示甲地坡度最大，C、D值最小，坡度最��；流速最快的是A。選A正確。

【2】注意到圖中右上角有個(gè)指向標(biāo)，根據(jù)圖P地?cái)?shù)值不是最大，排除A；河流甲處數(shù)值最大，坡度最大，位于上游，而丁出數(shù)值小位于下游，河流流向自甲向丁，為東南向西北，排除B；Q地位于河流的北岸，Q坡面向南，是夏季風(fēng)的迎風(fēng)坡，排除D。本區(qū)坡度較大，適宜林果業(yè)，故選C。

【題目】【2015·陜西】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 special(物種) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.

On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威脅)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 (種植園)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 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 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.

【2】The purpose of the text is to .

A. entertain B. advertise C. instruct D. persuade

【3】Where does this text probably come from ?

A. An agricultural magazine.

B. A medical journal.

C. An engineering textbook.

D. A tourist guide.
