Question

【題目】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】

本文介紹了美國研究人員成功地開發(fā)了一種不使用化學(xué)物質(zhì)的廢水凈化方法。就是借助于綠色植物。條件是水中的廢物可以作為植物的食物。這項(xiàng)新技術(shù)現(xiàn)在已在佛羅里達(dá)州的四個(gè)地方得到應(yīng)用。

【1】推理判斷題。由句子American researchers have successfully developed a way to clean waste water without chemicals. 美國研究人員成功地開發(fā)了一種不使用化學(xué)物質(zhì)的廢水凈化方法。可知，這是一種處理廢水的新方法。故選B。

【2】細(xì)節(jié)理解題。根據(jù)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，清潔廢水的技術(shù)是基于水中的廢物可以作為植物的食物。故選D。

【3】細(xì)節(jié)理解題。由句子American researchers have successfully developed a way to clean waste water without chemicals. 美國研究人員成功地開發(fā)了一種不使用化學(xué)物質(zhì)的廢水凈化方法�？芍�，這項(xiàng)技術(shù)被稱為一種新方法，因?yàn)樗�可以使廢水清潔，但不使用化學(xué)物質(zhì)。故選C。

【4】細(xì)節(jié)理解題。根據(jù)句子Four places in Florida are using green plants to clean their waste water. 佛羅里達(dá)州的四個(gè)地方正在使用綠色植物來清潔廢水�？芍�，這項(xiàng)新技術(shù)現(xiàn)在已在美國的一些地方得到應(yīng)用。故選D。

【5】主旨大意題。根據(jù)第一段的敘述可知，美國研究人員成功地開發(fā)了一種不使用化學(xué)物質(zhì)的廢水凈化方法。這項(xiàng)技術(shù)使用綠色植物。因此本文主要介紹了綠色植物被成功地用于清潔廢水。故選A。

用細(xì)節(jié)定位法來做細(xì)節(jié)理解題。

細(xì)節(jié)理解題屬直接解答性問題，是閱讀理解題中最簡單的一種，多數(shù)屬中低難度的送分題。但由于中考所占的比例很大，應(yīng)特別引起注意。

事實(shí)和細(xì)節(jié)題的命題特點(diǎn)是：把某詞語、某個(gè)句子或某具體事實(shí)用不同于原文的另一方式或句型表達(dá)，即同義改寫。解答這類題的竅門是：A)注意掌握英語的多種表達(dá)法；B）正確分析詞語在句中的作用；C）熟練運(yùn)用英語的句型轉(zhuǎn)換；D）讀懂題干所提出的問題，并準(zhǔn)確地找到文中涉及該問題的句子。

做細(xì)節(jié)題具體方法與步驟如下：

略讀材料,大概了解原文，掌握中心或主旨。

按文章的體裁，作者寫作的組織模式及有關(guān)的信息詞，如for example，first，second…等預(yù)測應(yīng)該到何處尋找自己所需要的事實(shí)。

③ 將自己精力放在尋找你所需要的細(xì)節(jié)上，快速通篇跳讀，眼睛自左至右，自上而下呈Z形掃視，直到找到細(xì)節(jié)出處，待找到含細(xì)節(jié)句子時(shí)，放慢速度，仔細(xì)核對比較內(nèi)容，直至找到答案。
