Have you seen Avatar 阿凡达? 此题出自2015年福建三明市中考英语真题及答案，2015年福建三明中考英语试题及答案 C Have you seen Avatar(《阿凡达》)? It’s a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images(图像)from the movie look as if they were coming straight towards you. More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies are more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why? When we look at an object(物体), each eye sees it at a differ ent angle(角度). Our eyes send the two images to our brain(大脑), and the brain puts them together. 3D technology uses two film projectors(投影机). One projects a left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can’t put together the images sent to our eyes. The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy(头晕的) or have headaches. A famous eye doctor said if your eyes can’t focus(聚焦) on the same object at once, you will have trouble watching 3D movies. 根据短文内容完成下列问题。 51. According to the passage, Avatar is a ______.
