课 堂 学 习
Talk about and answer the following questions.
If you smell gas in the kitchen, is it safe to call for help
with your cell phone Why or why not
Why should we NEVER leave babies alone in bathtubs,
even for 10 seconds
No, it isn’t. Because using a cell phone may create sparks. The sparks can easily set the gas on fire and cause a terrible explosion or fire.
Because babies can drown very quickly. They can drown in just a small amount of water, even in only a few seconds. It is very dangerous and may take their lives.
Many serious accidents happen in people’s homes. The kitchen and the bathroom are the two most dangerous places in the house.
Can people prevent certain accidents Yes. Many accidents happen because of people’ carelessness. So be careful!
