The mobile phone has been a part of our lives since the 1980s. It enables us to stay in contact with our family and friends at all times and in most areas. However, because of the quick acceptance and extensive usage of mobiles in our lives, we have missed out on an important step, namely, the appropriate (恰当的)use.

Driving a car  

Do not use your phone while you are driving ! You could concentrate on your conversation and forget to look where you are going, or you could take your eyes off the road to look at the phone’s display or to press in a number. Either way, you could cause a terrible accident.

In a restaurant

There is probably nothing more annoying than a diner receiving or making a call near you when you are in a restaurant. The icy glares you receive should be warning enough that it is not appreciated. Turn you phone off and enough that it is not appreciated. Turn you phone off and use your message service to return calls after you leave.

At the cinema

Do not give way to the desire to call a friend if the film is boring, or if you want to find out what happens. You could become the target of all the angry cinema customers.

At the theatre

There is no more icy glare than that of a theatre goer who has paid a lot of money to see a show and hears your phone playing a tone. It goes without saying that you will be seen as a socially unacceptable person in this situation.

In hospitals

This is probably the most important place to make sure your phone is switched off. Your phone can disturb life-saving electronic equipment in hospitals, so it is necessary that your phone is switched off before you enter.

On planes

Your phone might disturb navigational equipment and cause a horrible accident so you should switch it off before boarding a plane.

Have you ever wondered why birds sing? Maybe you thought that they were just happy．After all, you probably sing or whistle when you are happy．

Some scientists believe that birds do sing some of the time just because they are happy．However, they sing most of the time for a very different reason．Their singing is actually a warning to other birds to stay out of their territory．

Do you know what a "territory" is? A territory is an area that an animal, usually the male, claims as its own ．Only he and his family are welcome there ．No other families of the same species are welcome．Your yard and house are your territory where only your family and friends are welcome．If a stranger should enter your territory and threaten you, you might shout．Probably this would be enough to frighten him away．

If so, you have actually scared the stranger away without having to fight him．A bird does the same thing．But he expects an outsider almost any time, especially at nesting （筑巢） season．So he's screaming （高声尖叫） all the time, whether he can see an outsider or not．This screaming is what we call a bird's song, and it is usually enough to keep an outsider away．

Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs．You can see that birds have a language of their own．Most of it has something to do with attracting mates and setting up territories．
