People live there, and they speak all kinds of languages. 1 , there are about 7,000 languages and dialects (方言) in the world. People use those languages to communicate with others. They talk to each other. They learn about and 2 new ideas and knowledge. They can do all that in person and on the Internet. However, there is a(n) 3 . Not all 7,000 languages and dialects are on the Internet. A lot of them are 4 . According to a UNESCO study, 98% of the pages on the Internet are in just 12 languages. Also, over 50% of those are in English. That’s 5 for English speakers but not for many others. A part of the problem comes from computer 6 . They only have letters in English or the other main languages on the Internet. So, it’s 7 for the speakers of the missing languages to type their words. Another part comes from computer programs. They are also in English and the other main languages. So, to 8 them, the speakers of the missing languages must have knowledge of the main languages. People are working to solve this problem. They don’t want to 9 any of the world’s languages. They 10 want everyone to be able to use the Internet. Now, Wikipedia has articles in over 300 languages. It’s not much, but it’s a start. 1．A．In fact B．In person C．By accident D．For example 2．A．change B．refuse C．review D．share 3．A．idea B．problem C．tradition D．chance 4．A．missing B．waiting C．hiding D．repeating 5．A．boring B．difficult C．great D．funny 6．A．screens B．styles C．brands D．keyboards 7．A．impossible B．slow C．dangerous D．unfair 8．A．give B．buy C．pack D．use 9．A．spread B．avoid C．lose D．mention 10．A．still B．also C．only D．even 六、阅读理解。 Chemistry is usually thought to be more difficult than other subjects, at least for the beginners. There are some reasons for this idea. For one thing, chemistry has very specialized vocabulary (专用语汇). At first, studying chemistry is like learning a new language. Also, some concepts (概念) of chemistry are hard to understand. However, with hard work and careful study, you can learn this subject successfully—and even enjoy it. Here are some suggestions to help you develop good study habits and better understand the topics in the book: ·Firstly, attend classes on time. Listen to your teacher and take careful notes in class. If possible, always review the topics you have learned in class, and review your notes on the same day. ·Secondly, think carefully whether you really understand the meaning of a term or the use of an equation (方程式). A good way to test your understanding is to explain a concept to a classmate or someone else. ·Thirdly, pay attention to things which have something to do with chemistry in life. Watch or do experiments in class carefully. ·Fourthly, question often and do not be afraid to ask your teacher or classmates for help. You will find that chemistry is much more than numbers, formulas (分子式) and equations. It’s often used in daily life just like math and physics. Once you fall in love with it, you’ll get lots of fun. 1．How many suggestions does the writer give the readers? A．Three. B．Four. C．Five. D．Six. 2．The writer thinks that a good way to test your understanding of the formula “H2CO3” is to _______. A．write it on the blackboard B．read it aloud in class C．explain it to someone else D．ask others the meaning of it 3．According to the passage, which of the following is true? A．Chemistry is more often used than physics. B．Some concepts of chemistry are hard to understand. C．Studying chemistry is like learning our mother language. D．Chemistry is usually thought to be as difficult as other subjects. 4．The passage is mainly about _______. A．differences between chemistry and physics B．the importance of chemistry and physics C．why chemistry is hard for the beginners D．how students study chemistry Read and Explore Internet history was made on September 19,1982, when professor Scott Fahlman at Carnegie Mellon University, US, posted “:—)” on the school’s online bulletin board (电子布告栏) . Guinness World  Records called this smiley face the “first digital emoticon (数字表情符号)”. In the 40 years since, emoticons, and later emojis, have become central to our conversations online. GIFs and memes(表情包) also appeared. Now there are 3,600 emojis available for us to show our feelings, according to CNN. “They offer things that words aren’t saying. They said that when you say ‘okay,’ what kind of okay is that?” Jennifer Daniel, head of the Emoji Subcommittee for the Unicode Consortium, an organization in charge of choosing official emojis, told CNN. She said emojis are like our “body language” online. A 2017 study even found that the use of emojis helps us get the same satisfaction from talking online that we get from communicating in person. Just as language develops, so do emojis. The Unicode Consortium brings out new emojis every year. And it cares about race, gender(性别) and other aspects in emoji sets. In 2015, it released different skin tones(肤色). In 2016, different jobs were added, such as teacher and firefighter—along with female versions(版本) of these jobs. In 2019, emojis of disabled people were added, including emojis of blind people and people in wheelchairs. Some argue that we may depend on emojis too much. As people understand an emoji in different ways, misunderstandings often happen. The University of Valencia once studied the “thumbs—up” emoji. It found that when we use it alone, it serves many meanings: acceptance, liking, or closing the discussion. So what is the future of emojis? Will the emoji develop to become an international language? Or will emojis go the way of the emoticon and fade(消失) after the next big thing comes along? It is hard to predict—even technology and language experts are divided on the topic. What do you think? Tasks: 1．What has become central to our conversations online in the 40 years since? ___________________________________________________________________ 2．What can we know from the study in 2017? ___________________________________________________________________ 3．Why do misunderstandings often happen when people use emojis? ___________________________________________________________________ 4．Do you like using emojis when having conversations online? Why or why not? ___________________________________________________________________ 1 / 7 学科网（北京）股份有限公司 $ Unit 1 Language 课时3 Lesson 3 分层作业 核心知识速记 01基础达标 02能力提升 03拓展培优 04思维进阶 词汇 tip n. 小贴士、小费 method n. 方法 chant n. 歌谣 familiar adj. 熟悉的 phrase n.短语 structure n.结构 suit v. 适合 reward n./v. 奖励 image n. 图像 subtitle n.字幕 短语 as for 至于 make a difference 有所作为 work out 计划；进展顺利 by the way 顺便提一句 in order to 为了，目的是 jot down 快速记下 一、单词默写。 1. _______ [rɪˈwɔːd] n./v. 奖励 2. ________ [fəˈmɪliə] adj. 熟悉的 3. __________ [ˈmeθəd] n. 方法 4. ________ ˈstrʌktʃə] n.结构 5. ________ [ˈɪmɪdʒ] n. 图像 6. _______ [suːt] v. 适合 【答案】reward；familiar；method；structure；image；suit 二、词组默写。 1. 为了，目的是 ______________________ 2. 计划；进展顺利 _______________________ 3. 快速记下 _______________________ 4. 顺便提一句 _______________________ 5. 至于_______________________ 6. 有所作为 _______________________ 【答案】in order to；work out；jot down；by the way；as for；make a difference 三、根据要求完成句子​ 1. 这首英文歌谣的节奏能帮助孩子记忆单词。 This English ______ with its rhythm helps children memorize vocabulary. 2. 菜单上的小贴士建议这道菜搭配白葡萄酒。 The menu ______ suggests pairing this dish with white wine.3. 演讲结束后，大家鼓掌表示赞同他的观点。 When the speaker finished, everyone ______ to show their ______ with his opinion. 3. 心理学家推荐这种记忆方法来学习外语短语。 Psychologists recommend this memorization ______ for learning foreign phrases. 4. 电影配上字幕能让非母语者更好理解对话。 Movies with ______ help non-native speakers understand dialogues better. 5. 这个语法结构特别适合描述持续动作。 This grammatical structure particularly ______ for describing continuous actions. 6. 老师用图像展示这个短语的使用场景。 The teacher used an ______ to demonstrate the usage context of this phrase. 7. 完成任务的奖励是可以选择下周的活动内容。 The ______ for completing the task is choosing next week's activity. 8.看到熟悉的文化符号时，游客会感到亲切。 When seeing ______ cultural symbols, tourists feel a sense of connection. 【答案】chant; tip; method; subtitle; suit; image; reward; familiar 四 、单项选择 1．Mr. Hill has two sons.
