Watching TV is one of the activities I like to do in my free time. I love watching cartoons on Sunday afternoons and sports programmes on Sunday evenings. I also watch TV during the week after I have finished my homwork. At night, I really like watching movies. Watching TV is not the only activity that I do in my free time. My other activities is going shopping with my mother. However, when I have spare time, I spend more time watching TV than any other activities. Watching TV can help me relax and build me a huge knowledge of the open world.

Nowadays, English is one of the most major languages on over the world.  Therefore, it is used by a lot of people in many countriesIn high schools, English is a compulsory subject  that students have to learn. I like English so I always want to improve it. I learn it everywhere such as at school, at home, in the bus, on the internet, … I am  not good for listening and writing so I usually listen to radio, do exercises,  write letters and practice English skills with my friend. In the future, I will use English for my  job. My dream is becoming an English teacher in order to  teach my student about people and countries of England. I hope my dream will come true and so do you.

The subject I like best in school is geography and the subject I hate is arithmetic. Even from my younger day, I have been longing to know more about other countries and the people who live there.

Geography teaches me not only about my own country but also the neighouring countries and the world in general. From what I have studied, I have a longing to see London, Paris, New-York and Tokyo. I have heard much about Mount Fujiyama, the snow-capped mountain of Japan. I also want to see Japan during the cherryblossom season. I want to see New-York and its sky-scrapers.

Geography interests me because without visiting these places I learn about them in books. For pupils like me who are poor and cannot afford to visit these places, the knowledge of geography is all the most useful. It is perhaps the second best means of knowing more about other countries.( môn địa lý  nhé)Các chủ đề tôi thích nhất ở trường là vị trí địa lý và là chủ đề tôi ghét là số học . Ngay từ ngày trẻ của tôi , tôi đã được khao khát để biết thêm về các nước khác và những người sống ở đó . Địa lý dạy tôi không chỉ về đất nước của riêng tôi mà còn các nước neighouring và thế giới nói chung . Từ những gì tôi đã nghiên cứu , tôi có một khát khao để xem London , Paris , New - York và Tokyo . Tôi đã nghe nói nhiều về Mount Fujiyama , ngọn núi phủ tuyết trắng của Nhật Bản. Tôi cũng muốn nhìn thấy Nhật Bản trong mùa cherryblossom . Tôi muốn nhìn thấy New- York và nhà chọc trời của nó . Địa lý tôi quan tâm vì không đến thăm những nơi tôi tìm hiểu về họ trong cuốn sách. Đối với học sinh như tôi là người nghèo và không thể đủ khả năng để thăm những nơi này, các kiến thức về địa lý là tất cả các hữu ích nhất. Nó có lẽ là phương tiện tốt nhất thứ hai của hiểu biết thêm về các quốc gia khác .

Smart cards and mobile phones are becoming an increasingly popular way to make all sorts of payments. Even now, in Japan thousands of transactions, from paying rail tickets to picking up the groceries, take place every day with customers passing their handsets across a small flat-screen device. And predictions in the world of finance reckon that payments using mobile phones will have risen to more than $50 billion in the very near future.

What's the appeal of e-cash? Compared to cheques or credit cards, it offers the speed of cash, but more so. It takes just one tenth of a second to complete most transactions and as no change is required, errors in counting are eliminated. Fraud and theft are also reduced and for the retailer, it reduces the cost of handling money. Sony's vision of having a chip embedded in computers. TVs and games consoles means that films, music and games can be paid for easily and without having to input credit card details.

And what about the future of the banks? Within their grip on the market, banks and credit-card firms want to be in a position to collect most of the fees from the users of mobile and contactless-payment systems. But the new system could prove to be a "disruptive technology" as far as the banks are concerned. If payments for a few coffees, a train ticket and a newspaper are made every day by a commuter with a mobile, this will not appear on their monthly credit card statements but on their mobile phone statements. And having spent fortunes on branding, credit-card companies and banks do not want to see other payment systems gaining popularity. It's too early to say whether banks will miss out and if so, by how much. However, quite a few American bankers are optimistic They feel there is reason to he suspicious of those who predict that high-street banks may be a thing of the past. They point out that Internet banking did not result in the closure of their high-street branches as was predicted. On the contrary, more Americans than ever are using local branches. So, whether we'll become a totally cash-free society remains open to contention.

The word "embedded” in the second paragraph is closest in meaning to ____________.

A. manufactured

B. isolated

C. integrated

D. generated
