20．It is a beautiful day．The sun is shining and the birds are singing．What could be more interesting than a bike ride？But wait!
●Going for a bike ride is a lot of fun，but accidents often happen．Every year，about 300，000kids are taken to hospital because of bike injures．Some of these injures are so serious that children die，usually from head injuries．That's why it's so important to wear a bike helmet．Wear a bike helmet every time you ride，even if you are going for a short ride．
●Riding a bike that is the right size for you also helps keep you safe．When you are on your bike，your feet should be able to touch the ground．Before you ride，check your brakes（剎車） to make sure that they work well．
●Wearing_____ clothes can also help you stay safe．It helps other people on the road see you more clearly．And if they see you，that means they're less likely to run into you．Daytime riding is the safest，so try to avoid riding your bike when it's getting dark．
●It is helpful to learn some hand signals（手勢(shì)信號(hào)）．These are like turn signals and brake lights for bikers．They help cars and trucks know what you will do next，so they don't run into you．
