Hello, boys and girls! Today, I am going to talk about what you should do when a fire alarm go off. If you hear the alarm, stand in line at the door and wait your teacher to lead you outside. Stay close to your teacher and classmates. Don’t panic or get out of line, and try to remain quiet and calmly. Soon the firefighters will come and put out the fire. If it’s a false alarm and there is no fire, your teacher will lead us back to the classroom. If you notice that when someone is missing or hurt, tell your teacher immediately.

Last Friday I took the subway home as usually. Since our physics teacher had just teach us in class that the escalator(自动扶梯)worked, I decided to see how fast the escalator went. To my surprise, it went a speed of about 40 m/min. The next day, I went to a department store with her cousin Emily. I timed the escalator here too. I found that it was much slower, going about 30 meter every minute. Why? I check on the Internet and found the reason. Stores slow down escalators on a purpose, allowing customers more time to looking at their products.

In Africa, large animals, like elephants and lion, migrate to find food and water. A lot of birds travel to find more food and good weather. They are usual birds that eat insects. Some fish migrate to reproduce. Salmon (鲑鱼) can swims over 20, 000 km in their lives. They are born in some rivers in Ireland, Scotland and other places in northern Europe. The young fish swim down those rivers to the sea and into Atlantic Ocean. They live in the ocean after they are adults. Then they return to the river that they were born. They lie their eggs in the river and then they die. They do this, because of their eggs are safer in the river. Other fish can’t eat it.
