【10】 greatest

【解析】

这是一篇说明文。文章介绍了改变人们生活的两种药——阿司匹林和青霉素。

【1】考查定语从句。one of ___1___ is aspirin是一个介词 + 关系代词引导的定语从句，指物，只能用which。

【2】考查时态。根据时间状语in 1897，可判断出是发生在过去的事情，用一般过去时，所以填invented。

【3】考查固定短语。句意：它是由一种含有特殊物质的树叶或树皮制成，在1900年，第一次以药片的形式出售。in the form of以…的形式，该短语是固定短语，所以填the。

【4】考查时态和语态。它被用来推荐减少潜在的心脏病发作和癌症的发生。“它”和“推荐”之间是被动关系，用被动语态，表示主语现在的状态，用一般现在时，所以填is recommended。

【5】考查名词。句意：对于它如何帮助延长人们的生命和帮助人们抵抗疾病方面，有了更多的发现。作动词increase的宾语，用名词，所以填length。

【6】考查固定短语。句意：另外一种被证明对人类有益的药物是青霉素。beneficial to对…有益，该短语是固定短语，所以填beneficial。

【7】考查强调句。把it was和该空去掉，这个句子结构仍然完整，所以这是一个强调句，强调句的基本结构是it is/ was + 被强调部分 + that + 句子的其他成分，所以填that。

【8】考查固定短语。句意：由于青霉素的广泛使用，在战争期间，许多生命被救活。due to由于，该短语是固定短语，所以填to。

【9】考查名词单复数。句意：由于青霉素的广泛使用，在战争期间，许多生命被救活。Many修饰可数名词复数，所以填lives。

【10】考查最高级。句意：青霉素成为21世纪最伟大的药。文中表示“最伟大的”，所以填greatest。

小题7考查强调句。解题的关键在于准确判断出强调句。英语强调句型的基本结构是“It+be+被强调成分+that (who)…”。在该结构中，It was…that (who)… 为强调句的结构词，原则上说，若将其去掉，句子意思依然清楚、结构依然完整。如：1. It was Jack who stole our money. 是杰克偷了我们的钱。若去掉it was…who…，即为：Jack stole our money. 杰克偷了我们的钱。2. It was in May that you can see this kind of flower. 你在五月可以看到这种花。若去掉it was…that…，即为：In May you can see this kind of flower. 你在五月可以看到这种花。若去掉It was…that (who)…结构词，句子意思则不通、结构则不完整，那么就可能不是强调句。

Building a Greener Future

Year after year, Earth's precious resources are becoming increasingly scarce. Still people need materials to build new houses, office buildings and schools. There's only one solution to this problem: do more with less. That's what sustainable construction is all about. Advocates of sustainable construction believe the entire building process can be done without harming the environment, and by doing so, the earth is kept sustainable for future generations. To make these green buildings possible, however, the process must be implemented from the beginning.

Picture a city government that wants to build a green office building. The first thing these city planners would do is select a site with a small environmental impact. Ideally, they would choose a site that had already been developed, thus keeping the forests and grasslands protected.

Next, city planners would turn their attention toward the construction process. Only green materials could be used to build their office towers. These include wood, steel, and other materials that have been recycled from destroyed buildings. If possible, they have been manufactured, recovered, or resourced locally. The closer that these green materials are to the construction site, the less energy is wasted getting them to where they're needed.

Maintenance costs are the next important factors that need to be considered. City planners would design heating and cooling systems that use as little energy as possible. They would fit solar roof panels that will absorb the heat from the sun to power the building. Toilets and sinks designed to minimize water waste would be fitted throughout the building. These efficiencies don't just help to protect the environment; they can save money over the long run as well.

After all this was finished, the city planners would relax and maybe even throw a party. They have designed a building that was green at every step--the golden rule of sustainable construction.
