Giup Minh voi a Minh can bai gap

Mong mng giúp em ạ! Em cám ơn. Read the article about unusual hobbies. Five sentences have been removed from the article. Choose from the sentences A-F the one which fits each gap (1-5). There is one extra sentence which you do not need to use. A- Nearly everybody has a hobby, don’t they? B- She says that it all started when she had her thirteenth birthday. C- Now, you may think that’s crazy and you could be right. D- Activities such as stamp collecting, fishing or dancing are typical examples. E- Her bedroom is full of them. F- What makes it exciting, though, is the fact that it’s rather dangerous. We have all had a hobby at some time or other and if we really enjoy the hobby, it can become a lifetime interest. Most people’s hobbies are quite normal. (1)____________ . However, for some people these hobbies aren’t exciting enough and they look for something more exciting. One hobby, which is becoming more popular and is definitely exciting, is Parkour. A French teenager, David Belle, started it about 15 years ago. It’s a kind of gymnastic. (2)__________. If you want to be safe when doing a hobby, this one is not for you! You may have seen young people on TV doing it. Basically, Parkour involves finding new ways of moving across a city – jumping and climbing – often from high building. You need to have good balance to do it and it takes a lot of training to learn. As part of the learning process, you are taught how to do Parkour safely and sensibly. Collecting things may seem to be quite an ordinary hobby, but it can be unusual, depending on what you collect. One example of a unique collection is Joe Orville’s cheese collection! At the moment, he has collected over 300 kinds and the number is growing quickly. (3)____________. How can somebody collect something which will smell so bad after a while? Joe has the answer – he has a very large freezer, where he keeps all the different kinds of cheese. He says that he will never open or eat any of them; he just wants to try and find as many different cheeses as possible. Another collector who you would probably agree has an unusual collection is Janet Waite. She likes pigs and collects any kind of toy pig or anything that has a picture of a pig on it. (4)___________. Janet’s painted it pink too, so that it really is the best place to keep the collection. On her shelves there must be about 50 pigs – small ones, fat ones, big ones and funny ones. By her bed there is a pig lamp and her bed cover has a large picture of a black and white pig. If you stay in Janet’s room for too long, you’ll probably start to dream about pigs! One last example of an unusual hobby is Josie Curley’s. She makes special party hats for her friends and family. (5)___________. She wanted to make her party special and came up with the idea of making a hat for everybody she invited. She chose the number thirteen as the theme for her hats and made small paper hats with a large thirteen in different colors on the top. Her friends like them so much that she has made hats for quite a few parties. She’s even thinking about starting a hat business. So you see hobbies may just be for fun or a good way to exercise your hobby, but who knows? Your hobby may make you money in the future, too!
