六级阅读主旨题答题技巧及实战演练(20)

　　主要考查对文章进行概括或总结的能力，要求在阅读短文时，能够提炼文章的中心思想，体会作者的主要写作意图，充分运用逻辑概括能力，透过字里行间获取文章最具代表性的观点、论点及作者的情感倾向。

　　(一)出题形式：主旨大意题命题形式主要有三大类：一类是概括中心思想(main idea)型;一类是确定文章标题或主题(topic / title / headline)型;还有一类是询问文章的写作目的(purpose)。

　　1) What would be the best title for the text?

　　2) What is the topic of the text?

　　3) Which of the following best expresses the main idea?

　　4) The best title / headline for this passage might be ______.

　　5) The authors main purpose in writing the passage is ______.

　　6) Which of the following statements is best supported by the text?

　　7) Which of the following best summarizes the passage?

　　8) The main idea / The general idea / The main theme of this passage is ______.

　　9) The title that best expresses the main idea of the passage is ______.

　　(二)答案位置：大部分文章都有主题句(topic sentence)，主题句表达了文章的中心思想(main idea)，找到了主题句，也就抓住了文章的主旨大意。因此，主题句定位法是解答主旨大意题的一种行之有效的方法。主题句呈现形式通常有以下几种：

　　1)在开头出现;

　　2)在结尾出现;

　　3)在开头和结尾同时出现，首尾呼应;

　　4)有些文章的中心思想贯穿全文，并没有用一句话明确表达出来，这就要求学生学会归纳概括。

　　(三)实战演练

　　20 The computer is an electronic machine. It is a machine that solves problems as much as you do. As an example, lets trace the way you would add two numbers. Then, lets see how a computer would do it.

　　Step1. You collect information. That is, you either see or hear the numbers to be added.

　　Step2. You find a method to solve the problem. In this case, you remember how to do addition.

　　Step 3 You bring together the information , and the method

　　Step 4 You perform the operation, adding the two numbers.

　　Step5 You report the results of your work, either by writing down the answer or by saying it aloud.

　　All computers go through five similar steps.

　　Step 1 The computer receives information, or data, from the outside. It changes the data into electric language, called input.

　　Step 2 The computer has been given a program contain instructions for solving the problem. The instructions ate found in the storage or memory.

　　Step 3 The computer bring together the data from the input and the instructions from the storage. This is done by the computers control.

　　Step 4 The computer goes through the steps of the instructions on the data; this is called processing.

　　Step 5 The computer changes the result from electric language to human language. It presents the results in print or sound, called output.

　　Sometimes the five parts of a computer input, storage, control, processor , and outputare together in one large unit. Other times they are far apart and connected by wires. Often, large computers have one control and processing unit, with a number of separate memory, input, and output device.

　　What does the passage mainly tell us?

　　A The computer is an electric machine.

　　B Computer solve problems in the same way as people do

　　C How we add two numbers

　　D Computers have five parts together in one unit.
