四、(2025·南通市海安市模拟)阅读理解。〔人与自然——宇宙探索〕
An asteroid(小行星) striking our planet is an event of science fiction. You can find more than a few books and movies using this idea. But an asteroid hitting the Earth is also an event of scientific fact. Recently, it has been reported that an asteroid, named 2024 YR4, might be headed for the Earth. It has a chance of hitting the planet in seven years.
Don't run for cover just yet. "Asteroids, in general, are not something people should be overly worried about," said Davide Farnocchia, an engineer at NASA. NASA and its international partners have been tracking asteroids for years.
The chances of an asteroid strike are small, but when it happens, it's called an impact event. This usually doesn't pose a risk to the whole planet.
Asteroids are space rocks. When they fall to the Earth, they're called meteorites(陨石). Most small asteroids burn up in the atmosphere and never reach the ground. Bigger ones might go through the atmosphere, but they usually end up in the ocean or open areas. This causes little or no harm to human beings.
Even so, scientists are studying asteroids to learn about their risks. In 2021, a group of scientists published a report on this subject. It said that an asteroid strike could cause such strong shock waves that they would knock down trees and buildings as well as cause fires. If it hit the ocean, there would be huge waves in the sea.
These are all direct effects. In the long term, these impacts could change ecosystems(生态系统). For example, uncovered soil after an impact could change how rainwater flows. Dust from the impact could also change the climate.
One famous event was the 1908 Tunguska impact in Siberia. The 65-metre-wide rock caused bright nights for days from Siberia to the Atlantic Ocean. Another example was the 2013 Chelyabinsk meteor in Russia, which was 20 metres wide. It caused little damage on the ground, but its explosion in the air created a shock wave. Over 1,100 people were hurt and many buildings were damaged as a result.
Bigger asteroids cause more damage. The good news is that we can redirect asteroids. In November 2021, NASA sent up the spacecraft DART. Its target was an asteroid named Dimorphos. About one year later, DART successfully crashed into Dimorphos. NASA later stated that the asteroid's orbit(轨道) was changed. This was the first time humans had changed the movement of a space object on purpose.
1. What can we learn about 2024 YR4?
A. It is an asteroid in science fiction.
B. It is a newly discovered star in 2024.
C. It might crash into the Earth in 2031.
D. It dropped onto the Earth in 2024.
2. What is the underlined word "pose" in the passage similar to?
A. Cause.
B. Prevent.
C. Reduce.
D. Control.
3. (创新考法·组合式选择)What problems may an asteroid strike lead to?
① climate change ② rich soil ③ building damage ④ terrible fires ⑤ huge waves
A. ①②④⑤
B. ①③④⑤
C. ②③④⑤
D. ①②③④
4. What can we infer from the last paragraph?
A. Humans can reach any asteroid.
B. More asteroids can be discovered.
C. Humans can live on bigger asteroids.
D. An asteroid strike can be prevented.
