Question

【題目】 There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.

Another way is energy conservation（節(jié)能）, which means using energy more efficiently（有效地）. In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it.

Finally, renewable energy sources are used even though they are often expensive to develop. One form of these is geothermal energy. In certain parts of the world, the temperature of the earth increases 30℃ with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.

【1】From the passage we learn that oil______.

A.is quite easy to produceB.is not used most efficiently

C.is the most common energy sourceD.could be renewed only by new ways

【2】Why are the “special houses” mentioned in the passage?

A.To keep the cold out and the warmth in.

B.To show the excellent skills of the builders.

C.To be an example of energy conservation.

D.To be heated by different sources of energy.

【3】If the surface temperature is 15℃, how deep will you dig to get a temperature of 105℃?

A.One kilometer.B.Two kilometers.

C.Three kilometers.D.Four kilometers.

【4】Where does the heat of the earth come from?

A.The rocks inside the earth.B.The water pumped into the earth.

C.The temperature of the earth.D.The water on the surface of the earth.

Answer 1

【答案】

【1】B

【2】C

【3】C

【4】A

【解析】

本文介紹了人們節(jié)能的方法：一種方法是提高常見能源的產(chǎn)量，如煤炭、石油和天然氣。另一種方法是節(jié)約能源，這意味著更有效地利用能源。最后，可再生能源被使用，盡管它們的開發(fā)成本往往很高。

【1】推理判斷題。根據(jù)“One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.”可知，石油沒有得到最有效的利用，故選B。

【2】推理判斷題。根據(jù)“In some very cold countries people build special houses to save energy.”可知，這種特殊的房子是為了節(jié)能，故選C。

【3】推理判斷題。根據(jù)“In certain parts of the world, the temperature of the earth increases 30℃ with each kilometer down.”可知，地球的溫度每下降一公里就上升30℃。如果表面溫度是15℃，要達(dá)到105℃，105-15=90，90÷30=3，因此需要挖3千米才能達(dá)到這個溫度，故選C。

【4】細(xì)節(jié)理解題。根據(jù)“To get the heat, water is pumped down into the rocks and back up to the surface.”可知，地球的熱量來自地球內(nèi)部的巖石。故選A。

認(rèn)真閱讀題干，根據(jù)題干要求，在文中尋找答案所在的語句或段落，進(jìn)行分析理解，詞義猜測，推理判斷和概括歸納，選出正確的選項。例如小題2，根據(jù)“In some very cold countries people build special houses to save energy.”可知，這種特殊的房子是為了節(jié)能，故選C。
