四、阅读理解
(一)
Volcanoes are a threat all over the world. It can kill lots of people when it erupts(爆发). But some scientists have new ways to tell when they will erupt. Let’s learn about what a volcano is and high-tech detectives about volcanoes.
What are volcanoes
A volcano is a crack(裂缝) in the Earth. The opening is caused by gas and hot liquid rocks, called magma(岩浆). The gas and magma rise from deep inside the Earth. A volcano erupts when gas and magma push through the Earth’s surface. Magma that flows out of the ground is called lava. Lava can sometimes build up around a volcano and form a cone-shaped
mountain. Lava can also pour along the ground, destroying everything in its path.
High-tech detectives
The good news is that scientists can now help keep people safe. Scientists can get to an active volcano within 48 hours of the first sign of trouble. Researchers also have new ways to know when a volcano may erupt. They use satellites to watch volcanoes. They put sensors(传感器) at the base of a
volcano. Then they tune them to a satellite circling the Earth. The sensors feel rumbles(隆隆声) as magma and gases move inside the volcano. The satellites find the location of each sensor. A computer puts the information together to make a picture of inside the mountain.
These tools help scientists and researchers study the volcanoes. Then they can predict when a volcano may erupt.
( )1. What does the underlined word “lava” mean in Chinese
A. 岩石 B. 熔岩 C. 灰烬 D. 火山
( )2. What do researchers use to watch volcanoes

Keep away from danger
Hello, everyone. I’m Li Hua. For better understanding of the importance of disaster prevention, I’d like to give a talk around the topic of“Keep away from danger”. ____________
_________________________________________________________________________________________________________________________________________________________
A few days ago, I witnessed a big fire. A building caught a big fire. There was heavy smoke from the windows. People screamed in fear and ran in all directions.
__________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
That’s all for my speech. Thank you.
As students, we should learn to prevent fire in our daily lives. Don’t put anything explosive into the rubbish bin. Moreover, never play with fire. But if we are in a big fire, we should try to do something to protect ourselves. We can cover our mouth and nose with a wet towel and stay low to the ground. Then try to get out as soon as possible.
THANKS!
