五、阅读理解(B篇)
Volcanoes are threats all over the world. It can kill lots of people when it erupts. 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 on 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(岩浆). 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 and predict(预测) when a volcano may erupt.
( )1. What does the underlined word “threats” in the passage mean
A. Facts. B. Troubles. C. Chances. D. Topics.
( )2. What CANNOT lava do according to the passage
A. Help predict when a volcano may take place.
B. Destroy the things in its path.
C. Build up around a volcano.
D. Form a certain shape of mountain.
A
B
( )3. What do researchers use to watch volcanoes
A. Satellites. B. Computers.
C. Sensors. D. Pictures.
( )4. What is the purpose of the passage
A. To ask us to keep away from volcanoes.
B. To teach us how to keep safe when volcanoes erupt.
C. To tell us something about volcanoes and how to predict the eruption of volcanoes.
D. To encourage us to do more research on volcanoes.
A
C
( )5. In which column of a magazine can you read this passage
A. Safety.
B. Weather.
C. Environmental protection.
