Question

【题目】American researchers have successfully developed a way to clean waste water without chemicals. The technique uses green plants. The tests were carried out at a waste water treatment centre. The scientists put plants in narrow containers inside a glass building. One end of each container was a little bigger than the other end. Waste water was directed down the container through the plants' thick roots which absorbed the wastes in the water and used them for food. At the same time the plants produced natural gas.The gas could be collected and sold as fuel. Four places in Florida are using green plants to clean their waste water.

【1】The best title for this passage is______.

A. The Success of American Scientists

B. A New Way to Treat Waste Water

C. Waste Water and Green Plants

D. Advanced Technology in America

【2】The technique to clean waste water is based on the fact that ______.

A. green plants can be put in narrow containers

B. most green plants have thick roots

C. water can be directed down through the plants' thick roots

D. the wastes in water can be food for plants

【3】The technique is called a new way because ______.

A. it is cheaper than any other one

B. it can be carried out in a glass building

C. it makes waste water clean but uses no chemicals

D. it needs only narrow containers and green plants

【4】The new technique ______.

A. has been widely used in America

B. is still being tested since its first use

C. proves to be more valuable than expected

D. has now come into use in some places of America

【5】What is the main idea of this passage?

A. Green plants are successfully used to clean waste water.

B. Scientists are able to clean waste water.

C. Green plants have been used to clean waste water in Florida.

D. New ways of making waste water clean are better than ways of using chemicals.

【解析】

本文介绍了美国研究人员成功地开发了一种不使用化学物质的废水净化方法。就是借助于绿色植物。条件是水中的废物可以作为植物的食物。这项新技术现在已在佛罗里达州的四个地方得到应用。

【1】推理判断题。由句子American researchers have successfully developed a way to clean waste water without chemicals. 美国研究人员成功地开发了一种不使用化学物质的废水净化方法。可知，这是一种处理废水的新方法。故选B。

【2】细节理解题。根据句子Waste water was directed down the container through the plants' thick roots which absorbed the wastes in the water and used them for food.可知，清洁废水的技术是基于水中的废物可以作为植物的食物。故选D。

【3】细节理解题。由句子American researchers have successfully developed a way to clean waste water without chemicals. 美国研究人员成功地开发了一种不使用化学物质的废水净化方法。可知，这项技术被称为一种新方法，因为它可以使废水清洁，但不使用化学物质。故选C。

【4】细节理解题。根据句子Four places in Florida are using green plants to clean their waste water. 佛罗里达州的四个地方正在使用绿色植物来清洁废水。可知，这项新技术现在已在美国的一些地方得到应用。故选D。

【5】主旨大意题。根据第一段的叙述可知，美国研究人员成功地开发了一种不使用化学物质的废水净化方法。这项技术使用绿色植物。因此本文主要介绍了绿色植物被成功地用于清洁废水。故选A。

用细节定位法来做细节理解题。

细节理解题属直接解答性问题，是阅读理解题中最简单的一种，多数属中低难度的送分题。但由于中考所占的比例很大，应特别引起注意。

事实和细节题的命题特点是：把某词语、某个句子或某具体事实用不同于原文的另一方式或句型表达，即同义改写。解答这类题的窍门是：A)注意掌握英语的多种表达法；B）正确分析词语在句中的作用；C）熟练运用英语的句型转换；D）读懂题干所提出的问题，并准确地找到文中涉及该问题的句子。

做细节题具体方法与步骤如下：

略读材料,大概了解原文，掌握中心或主旨。

按文章的体裁，作者写作的组织模式及有关的信息词，如for example，first，second…等预测应该到何处寻找自己所需要的事实。

③ 将自己精力放在寻找你所需要的细节上，快速通篇跳读，眼睛自左至右，自上而下呈Z形扫视，直到找到细节出处，待找到含细节句子时，放慢速度，仔细核对比较内容，直至找到答案。
