题目解答
答案
【文章大意】短文讲述了3D的发展历史。
1.【答案】B
【解析】题目是：第一部3D电影是什么时候制作的?(A)在1844年；(B)1915年；(C)1950年；(D)2009年；根据第一段最后一句中“but it would be over 50 years later before the first 3D film was made in 1915.（但直到50多年后，第一部3D电影才在1915年问世）”，可知第一部3D电影是1915年制作的，故选B。
2.【答案】D
【解析】题目是：观看3D电影的观众被迫穿什么?(A)特殊的帽子；(B)耳机；(C)头盔；(D)一种眼镜；根据第三段最后一句“ Although there was a comeback, the technology still forced viewers to wear special glasses in order to be able to see the 3D effect.（尽管3D技术卷土重来，但观众仍不得不佩戴特殊眼镜才能看到3D效果。）”，故答案是D。
3.【答案】A
【解析】题目是：3D电视屏幕的缺点是什么?(A)它们很贵；(B)大多数人不喜欢他们的长相；(C)太小了；(D)大多数人对他们没有热情；根据第四段第二句“However, these new technologies are still very expensive, especially when compared to the cost of a regular flat-screen TV.（而，这些新技术仍然非常昂贵，特别是与普通平板电视的成本相比）”，可知选A。
4.【答案】A
【解析】题目是：是什么帮助3D技术卷土重来；(A)2009年的一部电影；(B)一台新电脑；(C)电视；(D)立体镜；根据第三段第一句“3D technology has made a comeback, though, with James Cameron's 3D film Avatar debuting in 2009.（随着詹姆斯·卡梅隆的3D电影《阿凡达》于2009年上映，3D技术卷土重来。）”，故答案选A。
5.【答案】C
【解析】题目是： 什么总是可以依靠的?(A)《阿凡达》；(B)一台3D电视；(C)二维技术；(D)电影工业；根据最后一段最后一句“In the meantime, we can enjoy the thrill of 3D when we feel like it, knowing that we will always have the older, two-dimensional technology to fall back upon.（与此同时，只要我们愿意，我们就可以享受3D带来的兴奋感，因为我们知道，我们永远可以依靠老式的二维技术。）”，可知，应选C。
6.【答案】B
【解析】题目是：下列哪一项是不正确的?(A)3D眼镜曾经在3D电影中具有噱头价值；(B)立体镜创造了第一部3D电影；(C)20世纪50年代人们对3D电影失去了热情；(D)普通平板电视比3D电视便宜；根据第一段第一句“T he technology for making three-dimensional (3D) pictures has been around since 1844 when an inventor created something called a stereoscope. This allowed photographers to take 3D pictures, but it would be over 50 years later before the first 3D film was made in 1915.（制作三维图像的技术大约在1844年就出现了，当时一位发明家发明了一种叫做立体镜的东西。这使得摄影师可以拍摄3D照片，但直到50多年后，第一部3D电影才在1915年问世。）”，可知立体镜和第一部3D电影间隔50几年，B选项是错的，故选B。
解析
根据文章第一段最后一句“but it would be over 50 years later before the first 3D film was made in 1915.”，第一部3D电影是在1915年制作的。
步骤 2：确定观众观看3D电影时需要佩戴的物品
根据文章第三段最后一句“the technology still forced viewers to wear special glasses in order to be able to see the 3D effect.”，观众需要佩戴特殊的眼镜来观看3D电影。
步骤 3：确定3D电视屏幕的缺点
根据文章第四段第二句“However, these new technologies are still very expensive, especially when compared to the cost of a regular flat-screen TV.”，3D电视屏幕的缺点是价格昂贵。
步骤 4：确定帮助3D技术卷土重来的原因
根据文章第三段第一句“3D technology has made a comeback, though, with James Cameron's 3D film Avatar debuting in 2009.”，詹姆斯·卡梅隆的3D电影《阿凡达》在2009年的上映帮助3D技术卷土重来。
步骤 5：确定总是可以依靠的技术
根据文章最后一段最后一句“we can enjoy the thrill of 3D when we feel like it, knowing that we will always have the older, two-dimensional technology to fall back upon.”，我们总是可以依靠老式的二维技术。
步骤 6：确定不正确的陈述
根据文章第一段第一句“T he technology for making three-dimensional (3D) pictures has been around since 1844 when an inventor created something called a stereoscope. This allowed photographers to take 3D pictures, but it would be over 50 years later before the first 3D film was made in 1915.”，立体镜和第一部3D电影间隔50几年，因此选项B是不正确的。
