Think about your daily life. Do you follow the same read to work every day? Do you sit in the same place in class? When you get dressed, do you always put the same leg or arm in first? You probably do, because we all have routines in our lives.

'Oh yes. I always do exactly the same things. I wake up at seven o'clock every morning, but I don't get quarter past seven. I switch on the radio and listen to the news. Then I go to the too and I brush my-teeth. I have a shower and dry my hair. Then I choose my clothes and I get dressed. I don'y eat anything for breakfast. I just have a cup of coffee. Then I go to work. Yes, it's always the same.'

Routines are very useful. but they also make you uncreative. So sometimes it's a good idea to break your routines. Get out of bed on the opposite side. Listen to a different route to work. Eat something different for brealfast. Change your routine. You never know, it could change your life.

Choose from the paragraphs A-H the one which fits each gap (124-130). There is one extra paragraph which you do not need to use. (7 points)

SUMMER CAMP: A SOAP OPERA

Every June, thousands of British students fly to the United States to spend their holidays working at summer camps. In return, they get a free return flight, full board, pocket money and the chance to travel. Lucy Graham joined a camp and spent eight weeks working with six to sixteen-year-olds.

I applied at the last minute and was so thrilled at the prospect of spending the holidays doing something more exciting than working in the local supermarket that I hastily accepted the only job left - in the camp laundry.

(124) ___ On arrival I was told by the camp director that I would be doing the washing for 200 children - on my own. Any romantic dreams I'd had quickly turned into nightmare reality. For the first week, the party sent out by the jobs agency - nine students, including me - became a full-time cleaning squad, getting the place ready for its grand opening.

(125) ___ The children's arrival also brought 50 American counsellors to look after them, and the opening of the laundry. At first, I had to work from 8.45 in the morning till 10.30 at night to get all my work done. Considering there was no hot water in the laundry and the machines were old, the washing came out remarkably well.

(126) ___ The kitchen workers, maintenance man and myself found that we were on the lowest level of the camp's class system. Our four British counsellor friends had a much better time. They got friendly with their American colleagues and were respected by the children. They were also given tips by parents after the holiday.

(127) ___ As for the camp itself, it had a large lake and excellent sporting facilities. But because organised activities for the children carried on into the evening, we usually didn't get the chance to use them. However, much more annoying were my room-mates, three 18­-year-old girls who worked in the dining room.

(128) ___ On top of that, the camp food was poor, with child-size portions; fresh fruit and vegetables were rare. One catering worker even stood over the pineapple rings, checking that you took only one each.

(129) ___ However, I couldn't set off as soon as the children left because we had to stay on for a few days, cleaning and closing down the camp. My last duty was to load up the rubbish bags and take out any clothes the children had thrown away, in case their parents asked about them.

(130) ___ What's more, without the free ticket I got to the US - and the rail ticket from my parents ­- I would never have seen Niagara Falls, gone up the Empire State Building or had my picture taken with Mickey Mouse at Disney World.

A They had never been away from home before, and spent most of the night screaming with excitement. Sometimes, the only way to get any rest was to pretend to be ill and sleep in the medical centre.

B We weren't so lucky. We were never invited to join in the evening activities. When we did manage to get out of the camp, our evenings tended to consist of eating ice-cream at the local gas station.

C As a result, the standard of the camp you end up in is usually a question of luck. However, the agencies do hold meetings where you can ask representatives from camps about the facilities and the nature of the work you will be expected to do.

D We swept out the bedrooms and scrubbed the lavatories, gymnasium and kitchen. We polished the cooking equipment, put up the sports nets and carried any luggage sent on ahead to the bedrooms.

E On the whole it had been well worth it. Despite the washing, the camp's plus points had been a beautiful setting, meeting a great bunch of travelling companions and doing far more reading for my university course than I would have done at home.

F All these disadvantages meant that Saturdays, our days off, were highly valued. The places we visited then, such as New York City, gave me an appetite for travelling later on. If I hadn't done that, I would have regretted it - there is so much to see and do and I was keen to get on with it.

G But with so many clothes to wash and dry, some did get mixed up. I had six­-year-olds marching up and telling me that their parents would be very angry if I didn't find their favourite sweater.

H I started to have my doubts while squashed between the swimming instructor and the sports teacher during the three-hour minibus ride to the camp, which was in a tiny town about 90 miles from New York City.
