Question

【題目】When you watch 3D movies or TV，you have to wear a special pair of glasses．The 3D glasses make the images from the screen look like they are there in the room with you．

Three-dimensional，or 3D，means having three dimensions（維度） : width，height and depth．3D technology（技術(shù)） is based on the way the human brain（大腦） and eyes work．Because thepupilsof a person's eyes are about 6．5era apart（分開），when we look at something，each eye sees it from a different angle（角度）．Our eyes send the two images to our brain，and the brain puts them together．The small difference between the image from the right eye and the image from the left eye allows us to see depth．

When we view pictures and television in two dimensions，each eye gets the same information．That is because the image has no real depth，and there is only one of viewing it．So the goal of 3D technology is to get a different image into each of the viewer．It uses two film projectors．One projects a left eye image and the other projects a right image．The 3D glasses allow us to see a different image in each eye．

While watching 3D films，we feel that we are in the same environment as the things we're watching．However，it also has its disadvantages．The 3D glasses work by controlling the amount of light that reaches the eyes．It makes the screen look darker．What's more，people with eye problems may get headaches if they spend too much time watching 3D movies，because their brains need to work harder to "read" the images．

【1】According to the passage，we can see 3D TV with the help of ____．

A. the exciting games B. the special glasses

C. the dark screen D. the image in the room

【2】The second paragraph mainly tells us ____．

A. how we see things in 3D

Answer 1

【答案】

【1】B

【2】A

【3】D

【4】C

【解析】試題分析：短文大意：該文主要介紹了3D電影，以及3D電影技術(shù)的科學(xué)原理。3D電影看起來是非常令人興奮的，越來越多的3D電影進入電影院。當(dāng)我們看一個物體的時候，每一個眼睛看不同的角度，然后大腦把他們放到一起。有些有眼睛問題的人看3D電影會感到頭暈或頭痛。

【1】細(xì)節(jié)理解題。根據(jù)短文第一句When you watch 3D movies or TV，you have to wear a special pair of glasses．可知人們觀看3D電影或電視時必須戴上一個特殊的眼鏡。所以該選B。

【2】段落大意題。細(xì)讀短文第二段可知人們是如何從三位角度看東西的，所以該選A。

【3】詞義猜測題。根據(jù)劃線詞后的介詞短語of a person's eyes以及下文描述可知劃線詞意為’瞳孔”.所以該選D。

【4】細(xì)節(jié)理解題。根據(jù)第三段中It uses two film projectors．One projects a left eye image and the other projects a right image．可知制作3D電影使用了兩個電影放映機。所以該選C。
