题目解答
答案
解析
本题主要考查对文章内容的理解以及词汇的运用。解题时需要结合上下文语境，分析每个空格处所需词汇的词性、语义和搭配，从而从所给的词汇中选出合适的答案。
第11题
- 前文提到太阳能是否能省钱取决于很多因素，如居住地点、房屋类型等，这里说“Things like insulation (建筑隔热材料), present energy costs, and the type of system you buy”，这些显然是额外的因素。
- “added”有“额外的，附加的”意思，“added factors”表示“附加因素”，符合语境，所以填“added”。
第12题
- 根据常识，石油和天然气等燃料是非常宝贵的资源。
- “precious”意为“宝贵的，珍贵的”，“precious fuel”表示“宝贵的燃料”，符合文意，故填“precious”。
第13题
- 后文提到“There is just not enough on hand to meet all our future energy needs”，说明石油和天然气的供应是有限的。
- “limited”表示“有限的”，“supplies of oil and gas are very limited”即“石油和天然气的供应非常有限”，符合逻辑，因此填“limited”。
第14题
- 这里表达的是我们现在开始节约能源和使用其他能源来源，是为了推迟听到自然资源耗尽的消息。
- “delay”有“推迟，延缓”的意思，“delay hearing those words”表示“推迟听到那些话”，符合语境，所以填“delay”。
第15题
- “run out of”是固定短语，意为“用完，耗尽”，这里说我们不用担心太阳在接下来的几十亿年里会耗尽能量。
- 空前有“the sun's”，所以要用动名词形式“running”，故填“running”。
第16题
- 后文提到太阳能是无尽的能源来源，还能减少污染问题，这些都是太阳能的优势。
- “advantages”表示“优势，优点”，“other advantages”即“其他优势”，符合文意，因此填“advantages”。
第17题
- 这里说太阳不像其他能源那样会引发很多问题。
- “cause”有“导致，引发”的意思，“cause problems”表示“引发问题”，符合语境，所以填“cause”。
第18题
- 结合语境，这里说化石燃料发电厂已经造成了高污染水平。
- “already”表示“已经”，符合文意，故填“already”。
第19题
- 前文提到为什么我们没有更多地使用太阳能，最大的原因是有更便宜的能源来源。
- “cheaper”表示“更便宜的”，“cheaper sources of energy”即“更便宜的能源来源”，符合逻辑，因此填“cheaper”。
第20题
- 最后说太阳能成本开始与石油和电力成本相当，它可能很快会成为国家能源供应的主要部分。
- “major”意为“主要的”，“a major part”表示“主要部分”，符合语境，所以填“major”。
