三、专题巧练
一
Computers are getting really inexpensive these days. Computer prices go down with time. However, that doesn't mean that you should wait forever to buy one at the lowest price. A computer can do many things such as playing games or helping with business. What a computer can help you is limitless. However, choosing a computer can be difficult. We hope the following suggestions will help you make a better choice.
First, decide what you are going to use the computer for. If all you need to do is managing home finances, playing some basic games, sending emails, and browsing浏览 the Internet, you are an average user. Nothing really "high-end"高端的 is needed.
Second, if you are choosing a computer for normal office work, only a mid-range computer processor is necessary. We actually recommend model A. It is more inexpensive with less cache快速缓冲存储器 than their model B cousins but is almost equally powerful.
Third, when you have limited your choices to a few computers, look at the secondary uses and programs. For example, if your main reason for buying a home computer is to play games, you may take computer A instead of computer B because computer A can also be used as a word processor.
Then, you need to consider your budget. It should be able to cover two prices. The first price is the price you must pay to take the computer home. The second is the price of additional programs and possible additions that you might want to buy at a later date.
Last but not least, be sure to try out the computer before you buy it. Sales people at computer shops are happy to help you choose the computer that will best suit your needs and cost you the least. 302 words

这是一篇关于购买电脑建议的英语阅读理解题，共4道小题，分别考查细节理解、细节计数、词义猜测和主旨大意。解题思路为：先通读全文把握文章核心（给购买电脑的实用建议），再针对每道题的关键词回原文定位，对比选项与原文信息，排除错误选项后确定正确答案。
【解析】
1. 细节理解题：根据原文第一段第三句“However, that doesn't mean that you should wait forever to buy one at the lowest price.”可知，B选项“我们不应该等最便宜的价格”正确；A选项与原文“Computers are getting really inexpensive these days.”（电脑越来越便宜）相悖；C选项原文是“What a computer can help you is limitless.”（电脑能帮你的是无限的），并非“一切”；D选项与原文“choosing a computer can be difficult.”（选电脑很难）相悖，故答案为B。
2. 细节计数题：原文明确提到购买电脑的步骤：First（确定用途）、Second（办公需求选机型）、Third（看次要用途）、Then（考虑预算）、Last（试用电脑），共5个步骤，对应选项C，故答案为C。
3. 词义猜测题：根据原文中“budget”所在段落的描述“It should be able to cover two prices. The first price is the price you must pay to take the computer home. The second is the price of additional programs...”可知，budget是指计划花费的总金额，对应A选项“某人计划花费的钱数”，故答案为A。
4. 主旨大意题：原文开头提出“we hope the following suggestions will help you make a better choice.”，全文围绕购买电脑的建议展开，对应C选项“分享购买电脑的技巧”，故答案为C。
