The t   ends of Earth’s axis are its poles. It t    Earth 24 hours to travel around its axis once. We look at the sun and say it ‘rises’ and travels across the sky, but the sun doesn’t really do s  . It is the turning of E    that makes us feel that the sun were moving across the sky. We can’t see the Earth is moving b    everything on Earth is turning around it.
As Earth moves around every 24 hours, the first half of Earth faces the sun and then the other h 8 . When our half of Earth is f 9  the sun, we say it is day. When our half is a    from the sun, we say it is night. It is the turning of Earth that tells us when to get up and when to go to bed.

How to beat sadness
We all have days when we are down, tired and unhappy. That’s OK. You need days like this, or how would you know you are happy? You’ll enjoy your good days even more when you have a few bad days. Even if sadness is a part of life, let’s try to make it small. Here are a few simple ways to help you feel better when you are feeling sad.
1. Stand up straight and this helps your energy flow (流动). When your energy is flowing freely, you can flow too.
2. Smile! It’s easy to do and have good results. This way can not only leave you in a good mood but also bring others a good mood.
3. Listen to music. It can be your favorite music. Some kinds of music work better than others, so try and find out what kind of music works the best for you.
4. Take some ‘me’ time. You can find pleasure in reading a book, watching a sunrise or having a hot bath, or something like that.
5. Exercise. Even something as simple as taking a walk will get your blood flowing. It is a great way to clear your mind of anything that makes you sad.
These ways will cheer you up when you are down, but don’t just use them when you are sad. Try and practice them every day to make them a habit. You will be surprised to learn that these simple ways will keep your sadness away. But if you are in a deep depression (沮丧), go to see a doctor.

What is it like being a film star? What is it like n front of the camera? Students from Steamboat Spring Middle School in the US could tell you exactly what it’s like. They recently got a taste of the life of a star.
A local movie company wanted to produce a film. All the actors in this film were to be students. Fourteen students were chosen from the school. The film, called Ruby vs Wolfgang, was based on the story of little Red Riding Hood(小红帽). It came with a twist(改变), however---the story was told from the perspective(看法) of the wolf.
Zoe Walsh, a seventh-grader, signed up to do behind- the- scenes work. But she soon found herself in front of the camera instead. She played a strange middle school student in the film.
“It is just for fun,” she told the Steamboat Today. “Just pretending that you’re someone else.”
But there were also difficulties. It was very cold during shooting. Students had to put up with snow and icy wind.
Lack(缺乏) of experience was another problem. The director Michael Staley said he tried to “help each student bring out the wolf ---or Whatever animal they representing---in themselves”
Erus Harrington, an eighth---grader, said he played a “nice, silly British guy”. He learned the British accent(口音) all at home.
“I just a kind of taught myself how to do it by watching videos,” he said “It makes me feel good after I do it because I’m proud of myself.”
The students will watch themselves on the big screen for the first time during the film festival at a local high school in May.
“I’m probably going to laugh at myself,” said Zach, the brother of Zoe.
小题1:Fourteen students were chosen as actors in this film, weren’t they?
小题2:Who did Walsh play in the film?
小题3:What were the two main problems for the actors?
小题4:How did Harrington learn the British accent?
小题5:Where will the students see the film acted by themselves on the big screen for the first time ?
小题6:What do the students think of being a film star after they got a taste of the life of a star according to the passage? (At least two different opinions)
