Our nearest neighbor is the moon. In the sky,  the moon and the sun seem to be of the same size because the moon is much nearer.

The moon makes the tides—the changes in the level of the sea. The moon and the sun together pull the sea. In some parts of the world,  the difference between * high tide' (when the sea is very near to the land) and ' low tide' (when the sea is far away from the land) is very big. This is very important for ships.

The moon is very different from the Earth. Gravity on the moon is six times weaker than that on the Earth. There isn't any air. During the day,  it is very,  very hot but at night it is very,  very cold. Nothing can live on the moon.

If the moon goes between the Earth and the sun,  we have an eclipse of the sun(日食) . The moon stops the light from the sun and we have night in the day.

If the Earth goes between the moon and the sun,  we have an eclipse of the moon. The moon goes into the shadow( 影子) of the Earth and it disappears for a few minutes.

Everything has a name．All people，places，and things have names．For example，Jenny is the name of a student from England．England is the name of a country．Cities and towns have names，too．Schools and office buildings also have names．For example，tomato，potato and bean are names of vegetables．Apple，orange，and banana are names of fruit．Names are important．We use names every day．When we meet a new person，we usually ask，“What’s your name?”It’s important to learn a person’s name．Most people have two names．Some people have more names．Names are different all over the world．In Jenny’s class．Jenny must learn the names of the students from all over the world．This is very difficult because the names are very different．
In the United States，most people have a first name，a middle name and a last name．Parents choose the first and middle names for their babies．There are names for boys and names for girls．The last name is the family name．Usually it is the father’s family name．In a family，the mother, the father, and the children usually have the same last name．
Sometimes a person has a nickname，too．A nickname is a special（特有的）name．It’s not a person’s real name．Abraham Lincoln’s nickname was“Honest Abe”．An honest person（一个诚实的人）always tells the truth，and Abe is short for Abraham．Because he was an honest person．his nickname was Honest Abe．Pele（贝利）is a nickname，too．The football player’s real name is Edison Aeraesde Nascimento，but everyone calls him Pele．Do you have a nickname?
Names are different all over the world．They can be long or short．but they are always very important

Everyone needs friends. We all like to feel close to someone. We can share 1.s       with our friends and turn to them for help when we are in trouble. In a word, it is nice to have a friend to 2.t      , laugh and do things with. Certainly, sometimes we need to be alone. We don’t always want people around. But we would feel 3.l       if we never had a friend.

To make 4.f      , you must be friendly. A cheerful person smiles. A smile always makes the others like you. Smile at someone and you are sure to get a smile5.b       from him.

Try to remember names. It6.m       your new friends feel happy when you call them by their names, 7.b       you don’t forget them.

No two people are just the same. If you don’t agree with other people, you should still be friendly. Do not argue, but 8.d      . You always lose friends if you argue too much. And you should think more of others than 9.o       yourself. It’s good for teenagers to have one or a group of good friends. This is very 10.i       in children’s growing up, because friends can discuss things which are too difficult to say to their family members.

There’s more good news for people who have friends. They live 11.l       than people who don’t have. Why? It could be that they12.a       happier. Being happy helps you stay well and it could be good just knowing that someone cares about you.

Can you imagine astronauts' everyday life in space? They also need to eat,  sleep, exercise and relax. They do the same things as us, but they do them differently.
On Earth, we put food on a plate. Gravity holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float （漂浮）away, and astronauts must eat carefully.
Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie the bag to a wall so that they won't float away at night.
Exercise is very important in space. On Earth,  your legs carry your body,  but in space, astronauts float, so they do not use their legs often. This is very bad for their legs, so they must exercise for thirty minutes every day.
After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families on the radio. Sometimes they just enjoy floating in the air.
