Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle (口哨) 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 (声称) 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 frightened 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 is screaming 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 to do with attracting mates and setting up territories.

If you have been joining in chat room conversations, or trading email with web pals （网友） , you have become one of the millions who write in a peculiarly short form of English.
And you’ve got a sense of humor about short forms like SOHF （=" sense" of humor failure） to describe Internet newcomers who don’t understand you.
Across the globe, every night teenagers and their elders are “talking online”, many of them all talking at the same time.
It’s fast: try talking to six people at once．It’s brief: three or four words per exchange．It takes wit, concentration, and quick fingers.
And it requires tremendous linguistic economy （语言省略）．There’s neither time nor space for explanations．Why consume precious key-strokes （键盘敲击） telling six friends you have to leave for a moment to take care of your little brother when BRB（ =" be" right back） will do?
Want to enter a conversation? Just type PMFJI （=" pardon" me for jumping in）.
Interested in whom you are talking to? Type A/S/L, the nearly universal request to know your pal’s age, sex and location．You may get 15/M/NY as a response from your pal.
If something makes you laugh, say you are OTF （=" on" the floor）, or LOL （=" laughing" out loud）, or combing the two into ROTFL （ =" rolling" on the floor laughing） .
And when it is time to get back to work or go to bed, you type GTG （=" got" to go） or TTYL （="talk" to you later）.
People want to write as fast as possible, and they want to get their ideas across as quickly as they can．Capital letters are left in the dust, except when expressing emotion, as it takes, more time to hold down the “shift” key and capitals．Punctuation （标点） is going, too．Many people talk on the Internet ______.

Talking to Teachers—Teachers are just people．Behind that desk, is a living, breathing human being．And just like any human being, they will probably be friendly to people who talk nicely to them．Teachers also seem to get along better with children who take schoolwork seriously and are prepared for class．And, just like any other human being, teachers like to be appreciated．The next time your teacher helps you solve a math problem or figure out a science project, say thank you with a smile.
Talking to Parents—Parents can be very supportive if their children ask for help．If you think there’s something your parents can do to help you socialize more or feel more comfortable around people, then ask them．Very often, parents want very much to help, but really don’t know what to do．Pick a quiet time of the day and ask to talk．Tell them how you feel．Maybe they had the same trouble when they were kids.
This Stranger Thing—This is always a tough one．How do you deal with a neighbor, the mail carrier, or someone walking down your street—situations that often seem to cause arguments between kids and parents．The answer to these questions will vary from kid to kid, from parent to parent because all cultures are different．Some folks live in small towns where a hello to everyone is “what’s done”．Then there are kids who live in the city who may have been taught not to speak to anyone they don’t know．If you’re having trouble with this and always feel awkward in these kinds of situations, you might want to talk to your parents or a teacher about it．Where do they think you should draw the line?

If you go into the forest with friends, stay with them always. If you don’t, you may get lost. If you really get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you by staying in one place.
There is another way to help your friends or other nearby people to find you. Give them a signal by shouting or whistling (打口哨) three times. Stop. Then shout or whistle three times. Any signal given three times is a call for help.
Keep up the shouting or whistling always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know that they have heard your signal. They will give two shouts, two whistles or two gun shots (枪声). When someone gives a signal, it is an answer to a call for help.
If you don’t think that you will get help before 
night comes, try to make a little house—cover up the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.
What should you do if you get hungry or need drinking water? You would have to leave your little branch house to look for a river. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way

If you ask people to name a person who had the greatest effect on the English language, you will get answers like “Shakespeare” “Samuel Johnson” and “Webster”, but none of these men had any effect at all compared to a man who didn’t even speak English—William the Conqueror.
Before 1066, in the land we now call Great Britain lived people in two main language groups. One was a Celtic language, the other was what we now call Anglo-Saxon (or old English), a Germanic language. If this had lasted, English today would be close to German.
But this didn’t last. In 1066 the Normans led by William began their rule over England. For about a century, French became 
the official language of England while Old English became the language of farmers. As a result, English wor
ds of politics (政治) and the law come from French rather than German. In some cases, modern English even shows a difference between upper-class French and lower-class Old English in its words. We even have different words for some foods, meat in particular, depending on whether it is still out in the fields or at home ready to be cooked.
This shows the fact that the lower-class farmers were doing farming, while the upper-class Normans were doing most of the eating.
When Americans visit Europe for the first time, they usually find Germany more “foreign” than France because the German they see on signs and ads seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the results of one
man’s ambition (野心).Before 1066, the two main languages spoken in the place wh
ich we now call “Great Britain” were __________.
| A．Germanic and French |
| B．Nordic and Germanic |
| C．Celtic and Old English |
| D．Old English and Germanic |

Why do Americans find France less foreign than Germany?
| A．Many signs and ads are in English. |
| B．They know little about the history of the English language. |
| C．Many French words are similar to English ones. |
| D．They know French better than German. |
Which of the following is the best title of the passage?

The Roman Emperor Claudius II was fighting many wars. He wanted a strong army, but many men did not want to be soldiers. Claudius thought the men wanted to stay at home to be with their wives and children instead of leaving to fight wars.
Claudius thought of an awful solution to his problem. He decided to cancel all marriages! No one in all of Rome could get married. Claudius thought that if the men couldn’t get married, the men would ignore the women and want to be soldiers.
Valentine, who was a priest (牧师), believed that people needed to get married. He thought it was wrong for people to live together without being married. So he secretly and illegally married couples anyway. He performed the weddings in secret places, so the Roman soldiers would not find out.
But they did find out. Valentine was arrested and brought before the Emperor. The Emperor thought Valentine was a well-spoken and wise young man, and encouraged him to stop being a Christian (基督徒) and become a loyal Roman. Valentine would not deny his beliefs, and he refused. He was sent to prison and was finally killed. While he was in prison, he sent out letters to his friends and asked to be prayed (祈祷) for by writing Remember your Valentine.
