【题目】—When did you buy the computer?

—I have ______ this computer for 5 years, but it still works well.

A.has B.have C.bought D.had

【答案】D

【解析】

试题分析：句意：――你什么时候买的这台电脑？――我买这台电脑有五年了。但还是运行正常。介词短语for 5 years强调过去开始的动作或状态一直延续到现在，用于现在完成时，现在完成时由have/has+过去分词构成，A、B错；buy是一个非延续性动作，不能与for，since等表示一段时间的状语连用，C错。故选D。

【题目】阅读短文，根据所读内容在文章后表格中的空格里填入一个最恰当的单词。

Left foot, right foot, left foot, right foot…you can travel fast or slow. The movement of your feet gets you where you need to go. But it also gets you so much more! Walking is such basic, simple exercise that almost everyone can take part in it.

Walking helps you in many ways. First, it makes your heart stronger. Studies show regular walking lowers your chance of heart disease. Walking for 30 minutes per day also helps control blood pressure. It can reduce your chance of having a stroke or developing some cancers, too. Want to lose weight? You need to burn 600 more calories each day you eat. Walking is the easiest way to do that.

Walking helps your brain health. As people age, their brains don't work as well. One in 14 people over 65 years old suffers from memory loss. Older people who walk six miles or more per week keep their brains in better shape. Putting one foot in front of the other isn't difficult. You don't have to think about it, so you can consider other things. You can consider problems or think of ideas. You can think over conversations again or just remember funny things that have just happened recently.

Walking is also good for your wallet. It saves the cost of going to a gym. Walk quickly for 150 minutes each week to get a good workout. A pedometer(计步器) can get you started. Begin with trying to take 1, 000 steps in 10 minutes to set the right pace.

You can make walking part of your day. Instead of parking right next to your office, park a distance away and walk. Do not take the elevator, but walk. You can even have walking meetings. They are what they sound like. Rather than sit, you walk and talk things over.

Make walking a habit, and see how it makes you feel.
