Pre-reading activities

1． Traditional classroom:

. Advantages: more direct communication between the teacher and students; a better learning atmosphere.

. Disadvantages: little interaction either among students or between students and the teacher; the teacher tending to dominate the class; writing on blackboard reducing efficiency.

Multimedia learning:

   . Advantages: more vivid teaching materials;

   . disadvantages: too many distractions with too many pictures and videos in multimedia classrooms.

Studying online:

   . advantages: being able to choose when and what you want to learn; easy access to the wide range of online information.

   . disadvantages: making it easier for students to copy answers from the Internet; lack of face-to-face communication between the teacher and students; the possibility for students to develop Internet addiction.

2. . I prefer the multimedia way of learning. A multimedia classroom is vivid with teaching materials presented in different ways: slides, pictures, and even movies. Compared with a traditional classroom, a multimedia classroom is more interesting.

  . To be frank, I prefer to study online. In this way I can manage my own time. I can have my own priorities and do things at my own pace. It is simply what I want.

3. . Yes. The Internet is indispensable in teaching and learning nowadays. It is hard to imagine what it would be like without the Internet. We would have no easy or quick way to learn about the latest development of teaching and learning. We would miss the many interesting online courses; we couldn’t communicate effectively with teachers after class. We just can’t afford to lose the Internet.

  . No. teaching and learning had been carried out long before the Internet came into being. And people did just as well without the Internet or the computer. It is true that the Internet makes teaching and learning more convenient and more efficient, but it is by no means indispensable. I’m sure we can still teach or learn without the Internet.

Reading comprehension

Understanding the text

1.

1.  A fleet of laptops, smartphones and Internet connectivity 24 hours a day.

2.  wireless Internet access anywhere and anytime on campus.

3. because smartphones could draw students’ attention and encourage sophisticated thinking.

4. because too much time online can mean too little time I real-life studying or exercising or visiting with friends. If we spend too much time online, we will be cut off from the real world.

5. they used the money to wire dorms with high-speed connections and equip their campuses with Wi-Fi networks.

6. Because the university was afraid that it’s technology was not as advanced as that of other universities, it gave away free Apple iPads to compensate for its inferiority in this aspect.

7. If a university can’t keep up with the rest f the world, or if it can’t provide high-bandwidth information as expected, it will be at a competitive disadvantage.

8. it is mainly because they want to provide students with the most advanced free system.

Critical thinking

1 .Yes, I think so. Internet access is a must on campus. We students need the Internet to do research for our study,  to obtain information to broaden our knowledge of the world, to communicate with family and friends, and to enrich our lives in our spare time.

 . No, I don’t think so. There are many potential disadvantages if Internet access is so easily accessible on campus. Some students may waste too much time I playing online games or chatting online, be tempted to visit “unhealthy” websites, or even become Internet-addicted and neglect their study.

2 .It sounds like an awful idea to me. Obtaining knowledge is only part of learning. Learning not only gives us a wealth of knowledge, it also provides us with great vision, strong principles, social abilities, good manners, interpersonal skills and many more valuable attributes. This obviously cannot be realized by learning at home only with the computer.

 .I think it is a good idea that students can study at home via the Internet in the future. Learning would become more flexible and accessible. This way, college education could become available to many more people, old or young, near or far, healthy or handicapped.

3 . The Internet and smartphones have become an indispensable part of our daily life because they don’t cost much and they make communication much more convenient. We can talk to people, or leave them messages almost anywhere and anytime. And very often we will get responses in no time.

 . With the Internet and smartphones becoming more and more popular, we are forgetting how to write with a pen or how to talk with people face to face. The more we use the Internet and smartphones, the less we meet our friends in real life. Even when friends meet face to face, instead of talking with each other, they all look at their smartphones, checking email or posting something on WeChat.

4 .Life would be unimaginable without the Internet or smartphones. I depend on them to do everything, from study to communication, from shopping to entertaining. Without the Internet, the backing systems, the communications systems, in fact all key aspects closely related to peoples’ life will collapse. Life without the Internet would be terrible and simply unimaginable.

 .Actually, I wouldn’t mind having a life without the Internet or smartphones. Without them, I would meet my family and friends face to face and spend more quality time together. I might take up some interesting hobbies or try something new. So, without them life might become even more colorful.

It is not uncommon to see teenagers smoking today. Some of them smoke because of peer pressure. When they see some of their friends smoking, they feel the pressure to try it out in order to “fit in” with the crowd. Some other teenagers smoke because they want to imitate adults or appear to be mature. Teenagers like to imitate their favorite stars and adults around them. So, parents who smoke may set a bad example for their children. In conclusion, the causes of teenager smoking can be attributed to peer pressure and their intention to look like adults.

伦敦地铁是英国的一个快速交通运输系统，服务于大伦敦的大部分地区。地铁系统因其他地铁隧道的典型形状也被称为地下管道。伦敦地铁始建于19世纪中期，是世界上最早的地下铁路系统。它的第一段地铁于1863年开始运营。自此，伦敦地铁不断延伸，发展成为一个包括12条线路、275个车站、铁轨总长超过250英里的地铁杰作，其中有45%在地下运行。就路线长度而言，它是世界上第四大地铁系统，也是车站数量最多的地铁系统之一。作为一个走遍伦敦的经济便捷的途径，伦敦地铁一向是每天数百万通勤者以及在节假日游历伦敦的游客的首选。伦敦地铁已成为伦敦的一个国际标志。2013年伦敦举办了各种各样的活动，庆祝地铁运营150周年，纪念这一里程碑。

China’s space industry was launched in 1956. Over the past decades, China’s space industry has created one miracle after another. In 1970 China launched its first man-made earth satellite, ranking China the fifth country in the world to independently develop and launch man-made earth satellites. In 1992 China began to carry out the manned spaceflight program. In 2003 China launched Shenzhou-5, a manned spaceship. The successful launch made China the third country to launch manned spaceships. In 2007 Chang’e-1,, the first lunar-orbiting man-made satellite, was sent to space. In 2013 Shenzhou-10, the fifth manned spaceship was launched successfully, laying the foundation for building the Chinese Space Station.

1 Teenagers and college students are more likely to become Internet addicts. Many teenagers lack self-discipline. Though their parents may watch them closely at home and only allow them very limited time to get online, once being away from home, these kids are likely to indulge themselves in the Internet. The same is true for college students. College students often use the Internet to help with their study, and they lack supervision from their parents if they live on campus. If they do not watch their time online and what they do with the internet, they may also become addicted to the Internet.

2 .Yes, I think so. A weak personality usually can’t resist temptation. Jack, my former classmate, definitely falls into this category. He knew for sure that online games would take up too much of his study time. However, he just couldn’t stop thinking about the games and completely indulged himself in this virtual world.

 . No, I don’t think so. A person with a strong personality may also become an addict. One of my friends had a very strong personality. He was independent and decisive, and he was always the leader among his friends. But somehow he became an Internet addict. So I think addiction to the Internet has nothing to do with ones personality.

3 If I have friends who unfortunately become Internet-addicted, I will help them: 1)set time limits. I will suggest that they should allow themselves a limited amount of time to spend online each day; 2)keep themselves busy. I will help them find activities to keep their mind of the Internet, e.g. meeting friends, taking up new hobbies, doing sports.

4 . “No Computer Day” is a good idea. If you shut down your computer for a day, you’ll possibly find a book to read, go out with friends, talk with your family, visit a museum, play basketball, or go to a concert. A day without the computer is a reminder that there are more rewarding things to do.

  . I don’t think it is a good idea. For people who depend on their computers for their work or study, they could do little or almost nothing without computers. Moreover, the business world may become out of order without computers, even for only one day.
