Passage 1: Environmental Protection

When I see litter on the street, I always pick it up. Before I throw away anything, I think about recycling. I often recycle plastic bottles and paper. While I'm at home, I turn off lights to save energy. As soon as I finish using water, I turn off the tap. We should protect our environment because it's important for our future.

Passage 2: Shopping and Disasters

Yesterday at 3 p.m., I was shopping at the mall when suddenly the building started shaking. It was an earthquake! While people were running out, I was trying to stay calm. The store usually opens at 9 a.m., but it will close tomorrow for safety checks. After the earthquake stopped, rescue teams arrived quickly. Everyone was scared, but fortunately, no one was seriously injured.

Questions:

1. What do you do when you see litter?
2. What were you doing at 3 p.m. yesterday?
3. What happened during the earthquake?
