D Now, we39。re always hearing about road accidents(事故 ), and when we39。re in a car we try to drive carefully, but how many of us take the same degree of care in our homes? Any large hospital will tell you the number of accidents that happen in the home is almost the same as those on the road. I don39。t pretend to be an expert, but I39。ve thought a lot about how and why these accidents happen and what we can do to prevent them. One of the monest and most dangerous causes of home accidents is wrong and careless use of electrical equipment(設(shè)備 ). People will continue to use a loose plug or pull out a plug without first turning off the power. In spite of warnings, one will carry an electric heater (電爐 ) into the bathroom when he is going to have a bath. Sometimes one fets to cut off the power before mending a lamp or something else. All these will cause accidents. So the rule about anything that works by electricity is: Switch off before you touch anything and don39。t pretend you know when you actually don39。t. If you39。ve got children in the house, it39。s always best to keep medicines of any kind out of their reach. Otherwise, they may be taken for candies or a new kind drink. When there are older people living with you, you have to take particular care in a number of ways in order to make them safe and happy. Fire, of course, is always a risk. So, remember not to dry clothes in front of fires, or leave stoves in the middle of rooms where they can easily be knocked over. And don39。t fet to keep the children away from fire. Smoking, too, may cause fire. So you39。d better give it up. Safety First may mean a little more time and care, but it may save you a lot of trouble. 48.

The sea is always present in Helsinki. When you take a walk over the great open space of the central square, you will hear seabirds screaming. When you take the tram, suddenly and unexpectedly, you are faced with a calm, shining blue sea. You may notice that people in Helsinki do not rush about as in other cities. Instead, they walk along the roads, politely letting other people by. A usual way to see Helsinki for the first time is to start out by the boats. You will walk by the elderly women selling fish and vegetables in the market square and find yourself in front of a beautiful park. You may enjoy a pleasant walk in the park for a few hours and then take the tram. Trams are the perfect way to get around in Helsinki. Watching the old houses, parks, theatres, churches, shops, restaurants and people in the streets, you may have a slightly sad film feeling to it. The pale summer nights
