2013中考英语阅读理解备考:At Blue Farm

2013-02-09 02:51:21 中考英语

  很多学生觉得英语难学,但事实上,英语和其他学科区别不大,知识点都完全出在书中。只要肯下工夫,一定会把英语学好,至少英语成绩不会被别人落下太多。通过今年的初三期末考试可以看出来,学生们存在的最主要的问题还是对教材不够熟悉。比如,今年的完形填空题出自教科书中的原文,但是5个填空部分很多学生都没有完全答对。其实,现在考试的趋势越来越回归教材,所以学生们一定要对教材非常熟悉。英语考试中的作文虽然不像语文作文那样占分比例很大,但这仍是一个重点。此次考试,学生们的作文情况也不是很理想。原因是学生们平时不愿意动笔。其实,只要对教材熟悉,写作的问题就不大。教材中的每个模块的第二、三单元都是一个主题,这个主题会告知写作内容。中考时的写作范围也不会脱离这些主题,肯定会是书中提到过的,所以,学生们要根据这些主题主动练习写作。

  寒假期间的复习重点可根据个人情况而定,但以下两方面不得忽视:1、完形填空和阅读每天要做四五篇。英语考试中完形填空和阅读所占分数非常大,这是一个容易得分的部分。所以,学生们在假期每天都要保证阅读数量。英语语感很重要,如果长时间不做阅读,再次复习时会费很多力气。2、初一到初三教材“过”一遍。复习英语的最好方式就是熟读教材,因为英语教材中几乎涵盖了所有知识点。寒假期间,初一到初三年级的全部英语单词要复习一遍,课文要通读一遍,要保证英译汉和汉译英都没有问题,这样会给开学后进入总复习提供很多帮助。

  B

  When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows-cow manure (粪肥), to be specific.

  Cows produce a lot of wastes. One cow can create 30 gallons of wastes each day. Now imagine the output of over 1,000 cows at Blue Farm. That's really a big amount.

  When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料). But now places like Blue Spruce Farm have a new way of using cow wastes. They use them to produce electricity.

  Here's how it works: A big machine moves back and forth cleaning the barn floor. "The cows aren't bothered," says Marie Audet. "They are animals of habit; they get used to it, and just lift one foot and then another to let it go by."

  The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester (化粪池) because what happens there is just like what happens inside a cow: Bacteria(细菌) get to work and continue to digest the manure.

  Methane gas (甲烷、沼气)in the atmosphere is known as a "greenhouse" gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That's an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (发电机).

  At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can't use themselves.

  A. make electricity B. produce fertilizer C. build their farm D. feed the cows

  52. How are the cow wastes collected into the digester at Blue Farm?

  53. According to the passage, which of the following is changed into electricity?

  A. The power of moving water. B. The heat of burning coal.

  C. The power of sunlight. D. The heat of the methane gas

  54. The new way of using cow wastes at Blue Farm might be best descr ibed as ______.

  A. reducing B. saving C. recycling D. changing

  55. What is the main purpose for writing the passage?

  A. To introduce a new way of making electricity B. To explain how a new energy works better

  C. To show a new rebuilding plan for a big farm D. To explain the reasons for green house effect
