问题描述：
People burn coal, gas and oil to get energy. But there are problems with these fuels(燃料). (A)________, these fuels cause pollution. Pollution makes the air and water unsafe for humans. Secondly, these fuels will not last forever. One day, we will run out of these fuels. Scientists are looking for new kinds of energy. One is heat from the Earth. We know that (B) 地球中央非常热. We cannot reach the center of the Earth, but in some place the heat from the Earth's center comes to the surface of the Earth. Perhaps you know about some of these places. One place is volcanoes(火山). It is very dangerous to go near an active volcano, (C)________ we cannot use the energy from this. Another kind of heat from the Earth is hot springs(温泉). In these place, hot water comes to the surface of the Earth. If this water is near a town, the hot water can be sent in pipes(管道) directly to people's houses to heat them. In Iceland, this is a common way to heat houses. (D) In Australia, scientists are looking for ways to make energy using hot rocks under the surface of the Earth. They want to pump(抽水) water onto the hot rocks .When the water hits the rocks, it makes steam(蒸汽). The steam is piped to power stations where (E) it is used to make electricity. The electricity can then be sent all over the country. 1. 在文中(A)和(C)的空白处分别填入适当的单词。 (A) ____ (C) ____ 2. 将文中划线部分(B)译成英语。 ____ 3. 将文中划线部分(D)改写为：In Australia, scientists are trying to ____ways to make energy ____hot rocks under the surface of the Earth. 4. 文中划线部分(E)指代的是 ____ 5. 从文中找出两个表示能源名称的词。 ____
最佳答案： 【分析】1. 由后面Secondly...可知，(A)处填Firstly“首先，第一”用于列举。(C)处应填连词来连接两句话，根据句意“到活火山附近是非常危险的，所以我们不能利用来自火山的能源”可知，填表示结果的连词so。\n2. that后是宾语从句。the center of“……的中央”；描述客观事实用一般现在时，故谓语用is；very hot“非常热”。the center of the Earth is very hot“地球中央非常热”。\n3. look for“寻找”，可用find“寻找”替换；“with+名词”作后置状语，表示“用……”。\n4. 蒸汽被输送到发电站，在那里蒸汽被用来发电。it指代的就是前面的steam。\n5. coal“煤”；gas“汽油”；oil“石油”；electricity“电”，这些都表示能源。
