Imagine you are an astronaut, you find a new planet that looks like the earth, and when you want to put the flag on it, you find out that this planet has already got population. What would you do?
The US astronaut, Charles “Chuck” Backer, in the new cartoon film Planet 51 just comes across this thing.
Planet 51 is a place where there is no human being. So Chuck arrives in the planet and wants to name it “the US”. But he suddenly finds himself surrounded by lots of little green aliens.
These aliens live in fear that they may be invaded by strange being. They have never seen an alien until Chuck arrives. They think it is terrible and they get ready to defend themselves or attack Chuck. They send him to the Planet 51 Alien Invaders Space Museum. Chuck is very scared and tries to escape. The only thing he can do is to make his spaceship work and fly back to the earth. Luckily, he makes friends with a young alien named Lem. Then the adventure begins.
Planet 51 is a science fiction movie. It tells us that whether we are on the earth or in another society with aliens, we should accept the things that are different in our lives and experience them actively. In this way, we can grow up and understand ourselves better by changing.
The film is very funny and full of happiness. Will Chuck return home? If you want to know, see it!

Dreams can happen in any of the four stages of sleep. The most memorable and clearest dreams happen in the last stage of sleep (also known as REM sleep). The sleep cycle repeats about four to five times every night. So you can see how a person has several different dreams in one night. Most people only remember dreams that happen closer to the morning when they are about to wake up. That you can’t remember those dreams does not mean they never happened.
The stages in the sleep cycle are organized by the changes in different brain activities.

Stage 1: You are entering into light sleep. In this stage, your eyes move rapidly. We call this NREM. The body gets relaxed and your body temperature lowers. Your heart rate lowers, too. The body is preparing to enter into deep sleep.
Stage 2: Also characterized by NREM. In this stage, the body temperature and heart rate drop again. You are completely asleep.
Stage 3: Still in the NREM stage, this is a deeper sleep still.
Stage 4: In this stage of sleep, your eyes move back or forward. We call it REM sleep. This stage happens at about 90-100 minutes after the beginning of sleep. Your blood pressure rises, heart rate speeds up. The majority of your dreams happen in this stage.
These stages repeat themselves throughout a night’s sleep.
Dreams can happen in ___________.
A. Stage 1 and 2 B. Stage 3 and 4 C. every stage

Plant scientists consider them as fruit. Most other people think of them as vegetables. Whatever you call tomatoes, there are many different kinds of this popular and healthy food.
There are two groups of the plants. Small tomato plants grow to about one meter. They can be planted rather close together. Some short kinds do not require special care and are often gotten crop by machines. Large tomato plants can grow over two meters tall. They also produce larger fruits.
People who grow only a few plants can place wire cages around each one. The cage can be made of wire fence material. The cage helps the plant grow taller and produce a better crop.
Tomatoes often need extra calcium (Ca), or the fruits may be ruined. Add lime to the soil can solve this problem. Dry lands may also ruin the fruits. Tomatoes need water regularly. The soil should never dry out completely. Dried grass or leaves placed around the plant can help hold water in the soil and stop the growth of unwanted plants.
Tomatoes are native to South America. The tomato is a member of the potato family. The leaves of the plant are poisonous, like the leaves of its relatives. Before the 18th century, people grew tomatoes only as pretty plants. They called the bright red fruit a “love apple”, but would not eat it.

A. They can grow to about 2 meters.
B. They can’t be planted close together.
C. Some of them don’t require special care.

A. protect the plant from being taken by others.
B. help the plant grow taller and produce a better crop
C. keep the plant from being eaten by animals
