By age 12, he had built a radio with spare parts. At 13, he began studying engineering. He was interested in a new technology of his time: television. Television works by sending pictures and sound to a screen using electrical signals. The first moving images were sent to TVs in the 1920s. Few people had TVs then, but many knew TV would be an important way to learn about the world. Early televisions had many limitations. They could only show black-and-white images, not color ones. Because of this, many inventors worked to solve these problems. González Camarena was one of the first with a solution. In 1940, he made a “tri-chromatic” (three-color) device, which used three colors: red, blue, and green. When it was connected to a black-and-white TV, people could see color images. The invention was a huge success. But the device was very expensive to make. He wanted everyone to have color TV, so he kept on working to make it cost less. By the early 1960s, he invented a cheaper way to show color on TV. He called it the “Simplified Bi-color System (SBCS).” It cost much less to produce. Starting in 1965, many SBCS TVs were made and sold in Mexico. González Camarena also believed that TV was important to educate children. His ideas helped create Mexico’s first educational TV network, “Telesecundaria,” which is still used today. Guillermo González Camarena passed away on April 18, 1965. Today, he is remembered as one of Mexico’s greatest inventors. 31．Why did González Camarena invent a tri-chromatic device? A．TVs were not perfect to send sound. B．TVs didn’t help educate children then. C．TVs were too expensive for people to own. D．TVs could only show black-and-white images. 32．What does the underlined word “limitations” in paragraph 3 mean? A．Special programs. B．Weak points. C．Unclear images. D．Loud sounds. 33．What was González Camarena’s view on television? A．It should help create TV network. B．Rich people should make it cheaper. C．It should be widely used and educational. D．There was no need to improve its technology. 34．What do you think of González Camarena according to the passage? A．A creative and caring inventor. B．A clever and friendly educator. C．A grateful and curious inventor. D．A smart and successful educator. 35．Where can we probably find this article? A．Great Inventors in History B．How Network Works C．Television User Guide D．The History of Television 第二节 阅读填空（共5小题，每小题1分，满分5分） 根据短文内容，选出适当的句子补全全文，使短文意思通顺，内容完整。阅读短文及文后A—E选项，选出可以填入各题空白处的最佳选项。 A Frenchman, Niepce, needed pictures for his business. But he was not a good artist. 36 He put it in a window of his house and took a picture of his garden. That was the first photo. The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. 37 In his picture, you could see everything very clearly, even the smallest thing. In 1840, photography was developed once more. Then photographers could take pictures of people and moving things. 38 So it’s not easy to take pictures. With the development of science and technology, a Chinese young man Wang Mengqiu, invented Hover Camera (无人相机). It can record people and things more wonderfully. He once studied at Stanford University in the United States. He became famous overnight because of the invention. Hover Camera records movements with a 13MP camera and takes 4K videos. You can use a smartphone to control it. It can follow you, flying or staying in mid-air. 39 It is the best choice for weddings, sports games and holidays because Hover Camera is convenient for users to carry. It can be folded, so it can be put into a small bag. 40 In the future, cameras will be designed better and better. People can take more lively photos and videos. A．He used a new kind of camera in a different way. B．In this way, it can get the perfect pictures. C．But the photographers had to carry many machines. D．When the power is low, it can land safely. E．So he invented a very simple camera in 1826. 三、项目情境（读写综合）（共两节，满分20分） 第一节 项目情境选择题（共5小题，每小题2分，满分10分） 【项目情景一】机器人产品推荐 科技博览会即将开幕，展出了七款新型机器人及智能产品（A—G）。请根据五位同学的需求，为他们推荐合适的产品，并将其字母编号填写在题号前的括号内。（其中有两项多余） 41 Jack’s grandfather lives in a small village alone.

【导语】本文主要讲述了中国古代丝绸的发现过程，以及王后教导人们制作丝绸，最终丝绸在古代贸易中占据重要地位和极高价值的故事。 【详解】1．句意：皇帝为他的妻子建造了一个非常美丽的花园，她在那里花了很多时间制作自己的裙子。 根据“In ancient China”，可知事情发生在过去，应用一般过去时，选项“built建造（过去式）”合理，其他选项“build（动词原形）；builds（第三人称单数形式）；was building（过去进行时）”时态不正确。 2．句意：就在她即将倒出它的时候，她注意到一些令人惊奇的事情——蚕茧正在散开！ 根据“something”，可知此处需要形容词作后置定语，修饰事物应用-ing形式的形容词amazing，表示事物本身的性质，选项“amazing令人惊奇的”合理，其他选项“amaze使惊奇；amazed感到惊奇的；amazingly惊奇地”词性或用法不正确。 3．句意：她小心翼翼地把它从茶杯里拿出来。 根据“took”，可知此处需要副词修饰动词，表示小心地拿出来，选项“carefully小心地”合理，其他选项“care（名词/动词）；caring（现在分词/动名词）；careful小心的（形容词）”词性不正确。 4．句意：而且，它是如此美丽，以至于每个人都想穿它。 根据“so beautiful that”，可知此处表示结果，丝绸非常美丽，所以应该是“每个人”都想穿，选项“everyone每个人”合理，其他选项“someone某人；anyone任何人；no one没有人”不符合逻辑。 5．句意：王后决定教大家如何用丝绸做衣服，但这并不容易。 根据“decided to teach”和“it wasn’t easy”，可知前后句意存在转折关系，应用but表示转折，其他选项“so所以；because因为；though虽然”逻辑不正确。 6．句意：王后告诉人们，除非他们密切关注每一个步骤，否则他们无法做出完美的丝绸衣服。 根据“couldn’t make perfect silk clothes”和“they paid close attention”，可知前后是条件关系。根据语境，表示“除非……否则不……”，选项“unless除非”合理，其他选项“as正如/因为；since自从/既然；until直到”逻辑不正确。 7．句意：丝绸成为一种有价值的贸易产品。 根据“valuable product”，可知此处泛指“一种”产品，valuable以辅音音素开头，应用不定冠词a，其他选项“an一（用于元音音素前）；the为定冠词；不填”不符合语法。 8．句意：古代中国人甚至把他们的丝绸运到遥远的国家。

根据空前的“much”，可知此处需要用形容词比较级。根据语境，表示“更高的价格”，选项“higher更高的”合理，其他选项“high高的；highest最高的；highly高度地”不符合语法。 10．句意：几个世纪以来，人们一直用它来交换金银。 根据全文过去时态语境及历史事实，此处描述过去发生的动作，应用一般过去时traded，其他选项“trade（动词原形）；trades（动词第三人称单数）；have traded（现在完成时）”时态不正确。 11．D 12．C 13．A 14．B 15．D 16．B 17．A 18．D 19．B 20．C 【导语】本文主要讲述了人口老龄化使照顾老人成为难题。护理机器人应运而生，它们不仅能提供生活照顾和体力帮助，还能给予情感陪伴，让老人感到自己有用和独立。 【详解】11．句意：然而，变老也会带来很多问题。 前文说长寿是好事，后文说变老带来问题，前后是转折关系，用“However”，表示“然而”，符合语境，故选However。“Later”后来，“Again”再次，“Instead”相反，均不符合。 12．句意：当社会中有很多老人时，找到护理人员就变得困难。 根据后文“There aren’t enough people to do this job”，可知找到护理是“困难的”，故选difficult。“cheap”便宜的，“lazy”懒惰的，“terrible”可怕的，均不符合。 13．句意：新型机器人可以为老人提供各种护理/帮助。

根据后文机器人帮助老人做很多事情，可知老人“需要”助手，故选need。“share”分享，“ask”问/要求，“miss”想念，均不符合。 17．句意：机器人提醒人们吃药、做运动和看医生。 根据前文“They can help old people with many things. ”，可知机器人是“提醒”人们吃药等，故选remind。“stop”停止，“refuse”拒绝，“choose”选择，均不符合。 18．句意：其他护理机器人做体力活。 根据后文“pick things up, help people walk, and lead groups in dances”，这些都是“体力”工作，故选physical。“useless”无用的，“dirty”脏的，“perfect”完美的，均不符合。 19．句意：一些公司让他们的机器人看起来很弱。 根据后文“They look like they need care”，可知它们被设计得看起来“虚弱的/需要照顾的”，故选weak。“polite”礼貌的，“common”普通的，“great”伟大的，均不符合。 20．句意：这样，人们会在机器人需要他们的同时关爱机器人。 根据前文机器人看起来需要照顾，人们会“关心/照顾”它们，故选care for。“throw away”扔掉，“worry about”担心，“clear out”清理，均不符合。
