Read the conversation and answer some questions.
(Kangkang and his foreign friends are talking about natural disasters.)
Kangkang: Hi, Maria. Last week, a hurricane swept through Cuba and hit the southern United States. Are your family in Cuba OK
Maria: Yes. My family members are lucky. They are now all safe and sound. Thank God!
Kangkang: The hurricane hit the coastal areas of Florida. Do you have any family members there, Michael
Michael: Yes, I do. My uncle’s family live in the western coast of Florida.
Maria: Are they all right
Michael: Not very well. The hurricane nearly broke his house into pieces. His left leg got hurt and bled badly.
Kangkang: Natural disasters are becoming worse and worse because of climate change, and I fear more are yet to come.
Maria: You’re right! There are many reports of natural disasters around the world all year round.
Michael: How terrible! We must learn how to protect ourselves during the disasters.
1. What does the phrase “safe and sound” mean in the conversation
2. What harm can hurricanes do to humans
3. Why does Kangkang think natural disasters are becoming worse
4. What does Michael think they must do to face natural disasters
He thinks they must learn how to protect themselves during the disasters.
Because of climate change.
They can break houses into pieces and hurt people.
It means “unharmed or out of danger”.
Further thinking
1. How much harm can a hurricane do to humans
2. Can we prevent natural disasters Why or why not
It can break anything such as houses, cars into pieces and cause losses of lives.
Yes. Because we did something bad to nature and it caused climate change. If we protect our nature well, we may help to reduce natural disasters.
No. Natural forces are so powerful that we can do nothing to change it.

Practice the conversation and role play it with your group members.
(Kangkang and his foreign friends are talking about natural disasters.)

Sample
A: What should we do in an earthquake Run or hide
B: Remember "Drop, Cover, and Hold On." Get under a sturdy table, protect your head and neck, and hold onto the table leg. Don't run—things fall from above.
A: What about a fire
B: Stay low to the ground and cover your mouth and nose with a wet cloth. Feel the door handle—if it's hot, don't open it. Seal the cracks with wet towels and go to a window to call for help.
A: And a flood
B: "Turn Around, Don't Drown." If you see water on the road, turn your car around immediately. Just one foot of water can float a car. Don't risk it.
A: Last one—a tornado
B: Go to the basement or an interior room with no windows, like a bathroom. Get in the bathtub and cover yourself with a mattress or blanket. Stay away from the roof and outer walls.
A: So the key is not to panic
B: Exactly. Stay calm and be prepared.
Activity 3
Incomplete plosion
Pay attention to the pronunciation of the letters in red in each sentence.
1. The snowstorm added to the difficulties for drivers.
2. He changed his plan because of the thunderstorm.
3. There was a snowstorm last month, and it lasted a few days.
4. The report reminded me of people’s efforts on environmental protection.
定义：
不完全爆破是指爆破音（/p, b, t, d, k, g/）在特定情况下不完整释放气流，仅作出发音姿势而不完全爆破的现象。
不完全爆破的三种主要情况：
(1) 爆破音 + 爆破音
当一个爆破音后面紧跟另一个爆破音时，第一个爆破音失去爆破
（仅作口型停顿，不释放气流）。
爆破音（6个）： /p, b, t, d, k, g/
示例：
/t/ + /k/: act kind [ k (短暂停顿) ka nd]
/d/ + /g/: bad girl [b (短暂停顿) g l]
/p/ + /t/: stop talking [st (短暂停顿) t k ]
Learn
(2) 爆破音 + 摩擦音/破擦音
爆破音后接摩擦音（如 /f, v, s, z/）或破擦音（如 /t , d /）时，爆破音不完全释放。
摩擦音（9个）：/f, v, θ, , s, z, , , h/
破擦音（2个）：/t , d /
示例：
/t/ + / /: white shoes /wa (短暂停顿) u z/
/d/ + / /: and that [ n(短暂停顿) t]
/k/ + /s/: taxi ['t (短暂停顿)si]
(3) 爆破音 + 鼻音/边音
爆破音后接鼻音（/m, n, /）或边音（/l/）时，爆破音通过鼻腔或舌侧释放，而非口腔爆破。 示例：/t/ + /n/: button /'b (短暂停顿)n/
注意事项: 连读中的爆破音：快速口语中，爆破音可能完全省略(如Is it→ / z (t)]/)。
Read the conversation and underline the incomplete plosions.
A: Is it raining again
B: Yes. And the heavy rain will
last till tomorrow afternoon.
A: That’s awful!
B: I hope the heavy rain will not
cause a flood.
A: What do you think of the flood
B: I think it’s very terrible and
dangerous.
