My husband had just bought a new washing machine for me. I decided to use it and I washed a lot of things.

    Everything worked well, I got ready for school as usual.

    When the bell rang and the students came in, I greeted them and told them what we were going to do that day.

    When I turned around to write on the blackboard, the class broke out into a roar(大笑声).

    They laughed and laughed. They laughed so much, in fact, that I was afraid the headmaster would be in to see all this.

    I asked the class to stop, but the more I talked, the more they laughed. I decided to pay no attention to them, and continued to write on the blackboard. When I did this, they roared even more.

    Finally, the teacher who had the room next to mine came in to see what all the laughter was about. When he came in, he started laughing, too! "Good heavens," I said," Will someone please tell me what is so funny?" "Oh, God," said the teacher." You have a brown sock stuck to the back of your shirt!"

    So that's how I found my husband's missing sock.

   "Oh, well," I said to the class." Let's just say you have had an unforgettable lesson on static electric(静电)."

Do you like taking a trip? Now many students like riding bikes to take a trip. But it may be dangerous. For your own safety (安全), do the following things. 

Wear a bike helmet because it can protect (保护) your head. Look for a helmet that is right for you. The best helmet can't protect you if it isn't right for you. 

Wear the right clothes. They can make you feel better. They can also protect you. Bright-colored clothes like white help people see you clearly--even in the nighttime. Don't wear dark-colored clothes like black or brown when you are riding a bike. 

Follow the rules on the road. Always ride on the right side of the road. Please first look behind you before you turn left or turn right. And don't ride too closely (接近) to the cars--the cars may stop and the door may open suddenly! Also, don't just listen to music when you are riding a bike. If you listen to music, you may not know there is a car behind you. 

If you follow these tips, you'll be safe riding on the road. 

 Hello, everyone. Let me tell you something about our winter holiday in America. Our holiday is from December to January. It lasts for about 3 weeks. During the holiday, we often take part in many activities such as winter school, winter camp(冬令营) and winter trips.

 In winter school, there are many courses(课程): Math, English, Science, skating and so on. We also do a lot of reading. Our parents let us choose any course we like.

 Winter camp is great fun. We have a good time with our friends. We also visit many places such as libraries and places of interest.

 Sometimes during the winter holiday, we travel to other countries or cities with our family. Last year, I went to China and Australia with my parents. We learnt a lot about Chinese and Australian culture. We saw some pandas in China and koalas in Australia. They were so cute! It was a wonderful trip.

Sam was a little worried because he would have an art class the following morning. It was his favourite class, but there was a 1 . Sam saw the world a little differently from everybody else. When he drew, 2 had different-sized wings(翅膀), and buildings had strange shapes. Every time he painted a picture, his teachers 3 classmates would be surprised. 

It was time for the art class. Nervously, Sam looked at the white piece of paper 4 him. 

"Good morning, class, " said Mr White. "Today, we're going to paint . . . "

Sam 5 , wondering(想知道) what the next word would be. "Please, " he thought, "not houses, not buildings . . . "

"We're going to paint 6 , " said Mr White, with a smile. "Yes! Great!" said Sam 7 . 

"No!" Mike 8 loudly from the other side of the classroom. "We can't paint that!"

"Sure, you can. Believe in 9 , " replied Mr White patiently. "Think about it, Mike. What makes you happy?"

"Umm . . . beaches, sunshine, and . . . ice cream!" said Mike. 

"Well, there you go. That's how you paint it. 10 working!" said Mr White. 

Sam was already 11 . He splashed(泼洒) a lot of paint all over the 12 . It was really 13 ! There were some shapes that we didn't have in the real world and the colours were so shining. The whole class cheered and Sam looked so 14 . 

From that day on, Sam was never 15 about the art class. He knew that no matter(无论) what he painted, they could be happiness. 

He enjoys painting and will keep painting.
