     Last week I visited my friend Pete in the new home where he lives with his wife and daughter. Pete used

to spend his holidays travelling the world, visiting the Louvre in Pairs or watching animals in Africa. Nowadays

he prefers to spend his holidays and weekends making his house look more beautiful. Like hundreds of

thousands of other British people, he has discovered the joy of DIY (Do It Yourself), which means if there

are any things that need fixing around the house, he will try to do the job himself.

     As he showed me the new kitchen he put together by himself and the newly painted walls, I asked Pete

where he got the idea from. He told me that his favourite source of ideas was a DIY programme on TV.

     This got me thinking about the popularity of DIY programmes in the UK. Nearly every channel has at least

one home or garden makeover show and there's even a DIY satellite channel.

     I guess it is not really surprising that DIY programmes are so popular. Two common sayings in Britain

—" an Englishman's home is his castle" and "there's no place like home"-show how important our houses are to

us. With the recent economic downturn, many people can't afford to buy a bigger house so they are looking

at how they can make their house better without spending a lot of money. DIY is the perfect choice.

     But be careful! I read a report that said over 230,000 people were hurt while doing home improvements in

the UK in just one year, including 41,000 who fell off steps and 5,800 who were seriously hurt by tools.

     I won't be going down to the hardware (五金) store. I'd rather watch DIY on TV with a nice cup of tea!
