? Are you a student or do you have a job?

2014-7-28

? I am a student at the moment. I am s

tudying English on a full-time basis at a Language School here in Guangzhou. We have classes in the mornings, afternoons, and evenings. Wednesday afternoons we are off, and are allowed to go swimming at a nearby hotel. We have a number of foreign teachers who assist us in the correct pronunciation and grammar of the language.
2014-7-28

? What is your major?

2014-7-28

? As I have been studying on a full-time basis at an English Language School, we have only one subject, namely English for Academic Purposes called EAP. We do reading and writing, practical speaking, and listening by means of cassettes. English is the language of the future, especially in the business world. What I mean to say is that when I am able to communicate well in English I will not only be able to go and study abroad and improve my qualifications, but also have mastered a very necessary tool for my future career.
2014-7-28

? What do you like most about your studies?

2014-7-28

? Well, I guess the speaking part. Please allow me to explain. Language is all about communication. So when I am able to communicate with someone in English, I feel that I have achieved something. I particularly like our free talk sessions with the foreign teachers. It gives me the opportunity to question them about their countries and cultures.
2014-7-28

? What kind of job would you prefer after graduation?

2014-7-28

? I would like to become a medical doctor. Please allow me to explain. Firstly, I would like to render a service in the community to which I will eventually belong. For example, I would like to assist the elderly that do not have the financial means to afford private hospitals.

Coin 法则---谈到一个问题的优点时， 也谈谈提一提缺点
? Question: How do you usually go to school, and why? ? Answer: I usually go to school by taking the bus, because it’s quite economical and convenient. What’s more, buses run much more frequently and can be easier to navigate. Although sometimes it is too crowded and time-consuming, I still think it’s a wise choice to me.
2014-7-28

比较法
? 通过比较同类事物，突出强调其中的一个内容 ? Question: What kind of music do you like best, and why? ? Answer: Light music takes my fancy most. It’s pretty relaxing and soothing, like some kind of therapy. Personally, light music is really a great medium that can enhance one’s quality of life. However, music like rock ’n roll is more fashionable. It is obviously not my cup of tea, since it’s always so exciting and aggressive.
2014-7-28

总分法
? 把话题涉及到的内容分开来说，而不是只注于某 个角度 ? Question: What do you usually do on weekends? ? Answer: Well, I’m used to doing sports on weekends. And it depends on the weather. If it’s a nice day, I usually go to play tennis with my best friend at a nearby tennis court. Playing tennis can help me improve both the physical functioning and

emotional health. If not, I mostly go to the gym to run on the treadmill or have yoga classes.
2014-7-28

6 W法
? 将6W结合起来（不一定六个都有），对于 很多话题，都可行 ? Question: What’s your hobby? ? Answer: My hobby is shopping. I usually go shopping with my mother when we are free,especially on weekends. And we like to go to Xidan, where many shopping malls and clothes chain stores can be found. I have to say shopping to me is the best way to get relaxed, and it’s really amazing.

备注
卡片由考官选择，不是考生自己选择。 ? ? 在拿到卡片后，考生有一分钟思考准备时间。 考官会给你纸笔作笔记。

?
? ? ? ?

做笔记可以采取你喜欢的任何方式。
如果卡片看不懂，可以问考官，但考官可以不作答。 一分钟结束后，考官会告诉你可以开始讲了。 在你说话的过程中，考官只听不说。 你说完后，考官一般会接着问一两个后续问题，只需简单作答即可。

?

第二部分结束后，考官将收回卡片，笔和草稿纸。

2014-7-28

. 如何利用一分钟准备时间
?
?

? ?

强烈建议大家利用好这一分钟的时间进行快速构思，并在稿纸上写上关键词 ，这一 方面是让考官觉得你事先未经准备，而是预防 “忘记”现象，也就是构思的 时候想得好好的，说的时候忘记了，为什么会忘呢，因为你说的时候是要看 着考官的，不免 有些紧张，一紧张就什么也想不起来了。
所以大家在平时练习的时候，也请按照这种方式进行，就是凭借关键词进行 架构，

?
?

同时按照卡片上的提示顺序一个一个往下描述即可，没有必

要临时重新组织 顺序。 而且，这回给考官一种印象：你实在临场发挥，这也是考官所希望看到的。

2014-7-28

Part Two 需要大家特别注意 的几个地方
? 第一：大家看到准备过的题目一定不要喜形于色。 ? 第二：思考的时候可以不看考官，但在描述的时候，一定 要看着考官说。 ? 第三：注意时态。 ? 第四：描述人的时候，注意he/she. ? 第五：结束的时候，不要说，that’s all. ? ? 如果你是在没话说了，可以使用下面这句话： ? Well, I’m afraid that’s all I can think of to say now, thank you.

? 1. 起——承——（合）
? Why do some people like collecting things? I guess there can be a variety of reasons. Some people collect things simply because they have too much spare time and need more personal pleasure. Others may think of collecting stuff as a means to make investments. Actually, I even know some folks collect things just to show them off to their neighbors.

2014-7-28

? Your turn:

What do you think of traveling? Do you like fresh vegetables?

2. 起—承—转—（合）
? How do people feel about rain?
? Humm, it seems to me like some folks love rainy days coz rain feels kind of romantic. ? In contrast, some others may totally hate rain coz they have a hard time getting around on rainy days. So you see, the feeling may vary from person to person.

2014-7-28

? Your turn:
What kind of climate do you like?

2014-7-28

3. 无厘头（off-the-wall）
? How can people control the pollution in your city? Well, you know, there’re plenty of ways to do that. For instance, if we control the number of cars, then there’ll definitely be less poisonous gas. And if we move the factories to other places, the air just won’t be so stuffy anymore. But as a matter of fact, it seems it’s very unlikely those things could be done immediately coz the city government already has too many things to take care of.

例句 Basketball is my biggest passion in life. Lots of children and teenagers are obsessed with computer games.. I’m crazy about LV bags. I’m huge fan of him. I absolutely adore you. I absolutely love Sichuan food. I’m into Korean songs. I’m so into you. Unlike most girls, I’m not very much into shopping. I’m not a big fan of photography. I dislike anything that’s oily and spicy. Dancing is just not my thing. I really hate travelling by train. I can’t stand the smell of it.

That’s exactly what the job requires.

I like it simply because… Well, there are a variety of reasons. First,…; second…

2014-7-28

One reason is that…; another reason is that… The primary/main reason is that… It’s primarily because…

You see, everybody wants to have a car. I think one reason is that a car does make life easier and gives your more freedom. Another reason is that an expensive car is a status symbol, so rich people use it to show off their wealth. I think the primary reason is that our university education focuses too much on exams and too little on practical skills. It’s primarily because we are selfish and short-sighted.

2014-7-28

It’s primarily due to… It’s mainly due to the fact that…

It’s primarily due to our selfishness and short-sightedness. It’s mainly due to the fact that people today are under heavy pressure from work and life, especially financial pressure. I’m not sure, but I guess one possible reason is that they rush into marriage and after a while they find that they are not actually right for each other. I don’t like cycling. For one thing, when I cycle along the road, I have to breathe the dirty air. For another, cycling is dangerous cos there’s so much traffic on the road.

I’m not sure, but I guess one possible reason is… For one thing… for another …

? ? ? ? ? ? ? ? ?

I’d like to talk about a shopping mall in my home city of Xi’an，which is in the downtown pedestrian zone, and it’s not far from where I live, just about ten minutes’ bus ride away, so it’s really convenient for me to go there. The mall is huge, you know, with 10 floors, and it looks really modern with shiny glass curtain walls. The inside is also amazing. It’s spotlessly clean and elegantly decorated. So it’s absolutely an enjoyment to be there. I go the mall quite a lot, about once or twice a month, sometimes alone, and sometimes with the company of my best friend.

2014-7-28

? ? ? ? ? ? ? ?

And most of the time, I go there to buy something, but some of the time, I just go window shopping there. As to why I love the place so much, the main reason is of course that the mall is a shopping paradise, offering an amazingly wide selection of goods. Most of them are reasonably priced, affordable to most people. The most important thing is you can always find something you really want to buy there, whether it’s a piece of clothing or electronic equipment. And everything there is name-brand stuff , so the quality is highly reliable.

2014-7-28

?

And another reason I love the place is because of its excellent shopping environment and outstanding service. It’s really pleasant to be there. Even just strolling around

? ? ? ? ?

and admiring all the exquisite products is highly enjoyable. The only problem is

that
on the weekends and holidays its packed with shoppers; you know it’s the most popular shopping place in the city, so I usually avoid going there at those peak

times.
I prefer to go there in the late afternoon after school/work, like at 6 or 7 o’clock. And it closes at 10, so I still have enough time to do my shopping.

I’d like to talk about ChengDu, which is the capital of SiChuan province in southwestern China. I’ve been to the city for a couple of times on summer vacation or at spring festival to visit my uncle. He went to the city after graduation from university and has been living there since then. ChengDu is probably one of the best known metropolises in China, just like ShangHai and ShenZhen, but it’s got its own unique charm. Shanghai is a financial center, ShenZhen is a commercial and industrial center, but Chengdu is more known as a leisure and tourism capital. In China, when people talk about Chengdu, what first comes into mind is usually its gorgeous scenery, wonderful de

licacies and beautiful girls. And also, the local lifestyle is envied by most people in China. The living cost in Chengdu is not very high and the pace of life is not so fast. It seems that people there don’t care so much about making money. For them, enjoying life is much more important. Maybe, that’s why they spend a lot of their time playing mahjong or enjoying delicacies.

Well, I’d like to talk about a very popular talent show on CCTV3. It’s called Star Avenue. And it’s something like American Idol and Britain’s Got Talent. The show airs twice a week The first time is on Wednesday night and the repeat is on Saturday night. So I’m able to watch it every time and I hardly ever miss it. It’s a talent show, so it’s all about the competition between contestants in the auditions and the other four levels of competitions, the weekly, monthly, quarterly, and the annual final. And the winners of each level advances/gets into the next level, and annual champion will be recommended to perform on CCTV Spring Festival gala.

2014-7-28

?

As to what type of people watch the show, as I know, it attracts people of all ages. Just like in my family, my parents and I are all loyal viewers of the show. And we usually watch it together. And we clap and cheer for a good performance just as the live audience in the TV studio. And we like to have a bet on who will be the winner each time. And the one who loses the best has to do the washing up. I love the TV show for a variety of reasons. But the most important reason I think is that the show is ordinary people like me to demonstrate their talent in front of a nationwide TV audience. In the past, we didn’t have anything like that. Only famous professional performers had the chance to give performances on TV. But now everybody can do that as long as they have what it take, courage and talent. And I’m really happy about that. If I was a good singer or something, I would also like to take part in it. But unfortunately, I don’t have any special talent.

五 : 1+1=？

我只是飘荡在天空的一朵无人顾忌的小小云彩，只不过停留在你摇曳的身旁，只不过想看着你快乐的舞蹈，没有烦恼、没有忧虑，一生就这样的欢快，雨滴从上帝的眼睛里拖出一条长长的弧线，找到了它找寻已久的归宿和它失落的感情，它轻轻的敲打着我在你身边的日子，昨天，就如风儿一般，轻盈的如梦幻般飘散！然而，记忆在雨声里疯长成一棵苍松，它的根系柔情的缠绕着我，让我不忍心离去，执着，正在催毁我！燃烧我，暗夜静静的在聆听，此刻，我放出那首熟悉的哥谣，以言语的心情，然后，徘徊在寂寞与自私之间，结果呢？只有以幼稚的方法骗自己！此刻，多想听到那个曾经如此熟悉的声音！带着迷昧的心思，然后，沉浸在情与爱的争执之中！结果呢？只能以那些可笑的回答自欺其人！我知道，等待的心是苦的，是痛的，所以我选择了逃避，放开能够快乐的爱！

1+1=？一次心跳加一次不成熟的表白等于一次心痛的教训！一个重重的跟斗家一场无泪的痛哭等于一步成长的代价……对不起，我玩不起，云无法停止在你的原点，我只能向前，飘飘荡荡的，寻找那一个连我都不知道的方向！风停了雨定了，我要走了，你不必牵挂你不要记恨，你我相识皆因偶然！我带走的只是一点点属于你我的回忆！

无风无雨的日子我会永远记得你！

幸福@@@@@@
