My father didn't know how to show love. He went to work every day. He often blamed (责备) me when I had made mistakes.

Once I broke my leg, my mother held me in her arms all the way to the hospital. My father pulled the car right up to the doors of the hospital. He looked really anxious (焦急的).

When I learned to ride a bike, I asked him not to leave me alone, but he said it was time. I fell and my mother ran to pick me up, but he stopped her. I was mad and I wanted to show him that I could ride it myself.

When I went to college, my mother wrote letters to me. He just sent money and a little note about how great his garden looked now because I wasn't playing football in it. Whenever I called home, he acted as he wanted to talk but always said, "Wait, Tim. I'll get your mother. "

All my life he said, "Where are you going? What time are you coming home? "Father's love is as great as a mountain, people often say. Didn't I realize his love?

Betty: Good morning, Alan! You look pale, are you all right?

Alan: I'm OK, but I saw an accident. A boy was riding his bike and listening to music on the road.

Daming: That's very dangerous.

Alan: I was waiting to cross the road. While the lights were changing to red, a car suddenly appeared round the corner. It wasn't going fast, but it didn't stop.

Lingling: Did the boy stop?

Alan: No. And the driver was talking on his mobile phone.

Betty: So, did the car hit the boy?

Alan: No, I'm glad to say. The car stopped just in time, but the boy fell off his bike and hurt his knee.

Tony: That's too bad.

Alan: So when you're on your bike, think about the risk of an accident! Pay attention, stop at the red lights and… what else?

Betty: Don't ride too fast.

Daming: Don't ride side by side with your friends.

Alan: Anything else?

All: Don't listen to music!

As an exchange student, I studied in France for two years. The first time I took a class in the chemistry lab, I was surprised to find that students were fully "armed". Everyone was wearing goggles (护目镜) and gloves. Safety comes first for science lab class.

My chemistry teacher Mrs. Louise usually gave us the instruction paper the night before the lab class and let us read it. During the class, she first went over the steps and then put us into groups of two to do the experiments (实验). What was special was that for every lab class, Mrs. Louise changed everyone^ lab partner to make them work with different classmates.

The class was often filled with laughter and screams (尖叫). We once tried to bum the chemicals and watch the colors of the flames(火焰). Different chemicals produced different colors of flames, including bright orange and dark green. Many students in my class were surprised. "Wow! That's so beautiful!" they screamed. Then they excitedly took pictures, posted them online and sent them to their friends. Mrs. Louise didn't get angry with us at all for our "noises". She herself even took photos with us!

After finishing an experiment, we had to write a lab report. If we had a big mistake in the experiment, we needed. to analyze (分析) why it happened and what we should do to avoid it next time. The lab reports were very important. They made up around 25% of our term grade.
