Work in pairs to name some com

2、mon social media home and abroad, and talk about why you tend to use some communication channels rather than others.,Warm-up,Facebook is a popular free social networking website that allows registered users to create profiles, upload photos and videos, send messages and keep in touch with friends, f

3、amily and colleagues. According to statistics from the Nielsen Group, Internet users within the United States spend more time on Facebook than any other website. Twitter is a free microblogging service that allows registered members to broadcast short posts called tweets. Twitter members can broadca

4、st tweets and follow other users tweets by using multiple platforms and devices.,Reference answers,Warm-up,Wikipedia is a free, open content online encyclopedia created through the collaborative effort of a community of users known as Wikipedians. Anyone registered on the site can create an article

5、for publication; registration is not required to edit articles. Wikipedia was founded in January of 2001. LinkedIn is a social networking site designed specifically for the business community. The goal of the site is to allow registered members to establish and document networks of people they know

6、and trust professionally.,Reference answers,Warm-up,Besides the above-mentioned communications channels, we have QQ, Microblog, WeChat, etc. The first one I used is QQ, because it first came into existence. The biggest advantage of it is that it enables me to send large attachments. I still use it n

7、ow when I am in front of the computer. I also use Microblog, but I use it less often now, because not many people use it now. This implies ones choice of communications channels is affected by others. Its main function, I think, is like a diary, which is a record of what I do, and what I think. It i

8、s also focused on current social events.,Reference answers,Warm-up,What I use the most often now is WeChat. It is a mobile text and voice messaging communication service developed by Tencent in China, first released in January 2011. It is the largest standalone messaging app by monthly active users.

9、 It is the newest app among the three, but probably has the most users now. WeChat provides text messaging, hold-to-talk voice messaging, broadcast (one-to-many) messaging, sharing of photographs and videos, and location sharing. Photographs may also be embellished with filters and captions, and a m

10、achine translation service is available. So I use it to send text messages, voices, photos both for fun and for work.,Reference answers,Warm-up,2 Work in groups. Each of you introduces one of your favorite apps. You may refer to the following points. name function intended users popularity how to us

11、e it room for improvements,Warm-up,I like to use many apps, such as Kuwo Music (酷我音乐), Meituxiuxiu (美图秀秀), Dazhongdianping (大众点评), and Tushubiji (涂书笔记). Many others must know the former three. So I will introduce the last one, Tushubiji. The name is interesting, because it reads like Dushubiji, whic

12、h means that one takes notes while reading. But the first word in this app is “tu”, which means “daub”: to highlight, or include a certain area of the photo you have just taken of a book page. Its main function is to convert the printed words in a book into electronic version. It is intended for tho

13、se who often read books, and who are relatively more high-tech such as teachers and students. It works very easily. First, you download it to your smartphone, and then log in it. But you have to register, or use your sina Microblog username if you already have one.,Reference answers,Warm-up,You open

14、 the app, take a photo of the few lines of a book page that you want to record, and then daub the part you want with your finger, press the tick () icon. Miraculously, you will see that the part of the photo you daubed just now has transformed into Chinese characters in a word file if the book is in

15、 Chinese. If the book is in English, you just need to press “English”, then the photo will be transformed into English words. Then press “next step” and “finish” to save the note. You may edit, and share the note if you like. The drawback is that the area you may scan and record is relatively small,

16、 may be just half a page. But its better than none. It is a very new app, and I hope it will be improved as time goes on.,Reference answers,Warm-up,2,Listening and Speaking,Topic One What is mass media?,1 Listen to a talk and choose the best answer to the questions.,Listening and Speaking,What is ma

17、ss media?,Listening and understanding,1 Which of the following is NOT a form of mass media?B. Alternative media. 2 Why do many media outlets have a web presence?A. To make full use of the Internet. 3 What are the major differences between mass media and local media?C. Local media has a smaller audie

It fails to address numerous interesting local stories. 6 Why is it important to under

19、stand mass media?C. Because it helps us to understand a people and culture.,2 Listen to the talk again and complete the summary.,Listening and Speaking,Listening and understanding,What is mass media?,Mass media is intended for 1) _, and it is sometimes used as a synonym for “2) _”. It takes the form

20、s such as 3) _, print media and the 4) _, which includes Internet and mobile mass communication. Many media outlets maintain a web presence to take advantage of the 5) _ of the Internet.As opposed to mass media, local media covers a much smaller 6)_, focusing on 7) _ of interest.

23、so be educational in nature. Work in groups to share your experiences of being educated through mass media, such as radio and television, etc.,Listening and Speaking,Thinking and speaking,Television can be a powerful entertainment and education tool for children. When I was a kid, my parents were bu

24、sy at work, so I spent most of my leisure time in front of TV. Reports have indicated that many families in the US have their TV on an average of six hours per day and the average child in fact, views 1,500 hours of television per year compared to spending only 900 hours per year in school. In this

25、case, the programming of TV proves even more important. I benefited much from TV programs.,What is mass media?,Listening and Speaking,Thinking and speaking,I enjoyed watching programs such as CCTV news, quiz shows, cartoons, and sports programs. These programs are both educational and fun. They are

26、a good source of knowledge and pleasure. For example, I especially like an annual CCTV program called “Touching the Heart of China”. From these heroic, devoted and unselfish people, I purified my soul, and learned to be a better person. From Animal World, I got to know the taxonomies of animals such

27、 as amphibians, birds, fish, mammals, reptiles, and invertebrates. I also learned that wolves are highly adaptable animals and can live in a variety of habitats as long as sufficient prey is available. Wolves can benefit natural plant and animal communities in a number of ways. Wolf predation can pr

28、event the,What is mass media?,Listening and Speaking,Thinking and speaking,overpopulation of prey, thereby helping maintain the natural occurrence of some plant and other wildlife species in ecosystems. I even learned to be more environmental-friendly from the public service advertisements, such as

29、to save water and electricity.However, studies have shown that television, and media in general, can also have a very negative influence. Some studies indicate it can shorten our attention span, cause obesity, create fear, and increase aggressive and anti-social behavior if exposure is unmonitored a

30、nd unlimited.But as long as we can control ourselves, its positive influence will always outweigh its negative ones.,What is mass media?,Topic Two Social media users are happier and more engaged,1 Social media is a relatively new term compared with mass media. It has recently become part of mainstre

31、am culture. The talk you are going to hear is about how it affects our daily life, personality and behavior. Listen to the talk twice and note down the keywords of the negative and positive aspects of using social media, and relevant information of a study by Pew Research Center.,Listening and Speak

32、ing,Social media users are happier and more engaged,Listening and understanding,The negative aspects: making people less sociable, self-centered, get wrapped up in texting or spilling their innermost secrets online without ever relating to others concerns; hurting users relationships and pushing the

33、m away from participating in the world,Listening and Speaking,Social media users are happier and more engaged,Listening and understanding,The positive aspects: making people have “higher measures of social well-being”, more trusting, have more close friends, get more support from those friends and m

34、ore politically engaged; improving communication between people; bringing group members attention to an issue; putting users in touch with old friends; reviving other long-dormant relationships; making people have more close relationships and more likely to be involved in civic and political activit

35、ies, feel a sense of pride and accomplishment about their contributions,Listening and Speaking,Social media users are happier and more engaged,Listening and understanding,The study: 1) more than 2,200 American adults 2) Internet & American Life Project 3) communications 4) 85 pages,Listening and Spe

36、aking,Social media users are happier and more engaged,Listening and understanding,2 The talk mentions that some people think online social communication is largely self-centered, and that folks are busy with texting or spilling their innermost secrets, without ever relating to others concerns. Work

37、in groups and have a discussion about your understanding of this topic.,Listening and Speaking,Thinking and speaking,Social media users are happier and more engaged,I agree with the statement. Online users may have no clue as to their relative status, and norms for interaction are not clear, so peop

38、le tend to become more arrogant, self-centered and less inhibited. This will bring about hostile language and creates a toxic climate which harms the healthy growth of relation on the Internet.Since online communication is not face to face, the users may not know each other. They will thus become mo

39、re selfish, rude and uncaring. They act as if they are the center of attention, and everybody should feed into their ego, and listen to what they say. They have no true empathy or respect for other people, and they use bitter and sarcastic language. When other people disagree, many will curse or use

40、 dirty language.,Listening and Speaking,Thinking and speaking,Social media users are happier and more engaged,It is true that most people are busy with posting what they have eaten, where they have been to, what they have bought, etc. The social media have been reduced to a platform where narcissist

41、ic people show off. What they have posted cannot arouse general publics interest. Their main focus is on themselves, instead of the common issues people are concerned with.The social media, as the name indicates, should have a higher aim, that is, it should focus on the social issues, and play a mor

42、e active role in improving the society, instead of a place for those with a big ego to brag about themselves.,Listening and Speaking,Thinking and speaking,Social media users are happier and more engaged,I dont agree with the statement. First we need to define what self-centered means in this context

43、. My understanding is that it means people tend to focus on the things that are related to themselves. It does not mean “selfish”, “narcissistic”, or “big ego”. If my understanding is right, there is nothing wrong with a bit being self-centered. Our life is already full of all manner of stress; soci

44、al media provides us with an opportunity or outlet to share our feelings or relieve our pressure. Thus for some people, this sort of social media serves as a diary. They record how they feel, what they do, etc. with Microblog or WeChat.It is not the obligation of social media to take others concerns

45、 into consideration. If you do care about social events, you can very,Listening and Speaking,Thinking and speaking,Social media users are happier and more engaged,well use this platform to show your concern and viewpoints. But if I am not interested, I am not obliged to do this. I have my own right

46、to decide what to say and what to post if I am not hurting others. If you are not interested in my posts, you can simply ignore them. Why should I be labeled as “self-centered” in a negative sense?The fact that social media can be used for other civic and political activities does not mean it has to

47、 be like this. The main function of social media for an individual is to keep in touch with other people and voice out his or her own feelings or opinions.,Listening and Speaking,Thinking and speaking,Social media users are happier and more engaged,Topic Three The era of “we-media”,1 Listen to the t

48、alk and choose the best answer to the questions.,Listening and Speaking,The era of “we-media”,Listening and understanding,1 Why do some people believe that “we-media” may make traditional news outlets outdated?B. Because “we-media” can almost be accessed everywhere in the world. 2 What is the main r

49、eason why mainstream media websites still draw hundreds of millions of visitors each month?A. Because they assign stories to professional journalists. 3 What is the strength of traditional media organizations?D. They can create a combined package of news. 4 Why are BBC and CNN mentioned?C. To show that some media organizations have already tried to search for more channels. 5 Why do some of the amateur bloggers give up neighborhood blogs?B. Because they are too busy.,
