题目内容
The light bulb ______ by Edison in the middle of the 1780s.
| A．is invented | B．was invented | C．invented | D．invent |
B
解析试题分析：句意：电灯是爱迪生在18世纪80年代中期发明的。应用被动语态的过去时。句中有in the middle of the 1780s表示18世纪80年代中期，是一个过去时间，故用一般过去时的被动形式。
考点：一般过去时的被动形式
点评：被动是中考中必考的语法点。解答好此类被动语态的题目，首先需要对句意有充分的理解，其次注意被动语态的基本形式。对于各个时态的被动语态，学生在平时的学习中都必须了然于心，中考英语中很亲睐考察将来时的被动语态，即will+be+done.
同步轻松练习系列答案
课课通课程标准思维方法与能力训练系列答案Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists (手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.
Enjoy your computer, but use it safely.

The Bermuda Triangle(百慕大三角)is in the Atlantic Ocean, near Florida in the USA. During the past 60 years, more than 1,000 seamen in ships and pilots in planes have lost their lives. It is known as “The Triangle of Death”for its strange seawater and sudden storms. What’s the strangest is the light of the seawater, which looks so bright that it can be seen even from an outer spaceship.
At 2:00p.m. on Dec. 5, 1945, five planes took off in fine weather from the airport of Florida, on a training task. Two hours later, the leader in the sky radioed that he was “completely lost”. Then there was silence. Another plane was sent to look for them and also disappeared.
One of the largest ship that had disappeared in the triangle was an American coal ship, 500meters long. The weather was good, and there were no messages for help before it was “gone”. No broken ships or dead bodies have been found so far.
No one is able to tell how all these accidents have happened. A group of Japanese scientists were there to see what it was really like in 1995, but nothing has been heard of them ever since.
