Unit 6 Living with nature
一、阅读理解，本大题共5小题，每小题4分，共20分。阅读下列短文，根据短文内容选择最佳选项。
People have always been very interested in space, but space can also be dangerous, with big rocks called asteroids （小行星） moving around. Recently, a small asteroid named “2024YR4” has caught lots of attention. On February 7th, 2025, it was reported that the asteroid has a 23% chance of hitting the earth in 2032. To keep our earth safe, Chinese scientists are working hard together.
Discovered in December, 2024, “2024YR4” is thought to be 40 to 100 meters wide. Although it’s very far away, over 48 million kilometers, Chinese scientists are watching it closely. They want to find more details （细节）.
________. Chinese scientists plan to make use of special telescopes （望远镜）. These telescopes, with powerful cameras and smart software, will help scientists observe （观察） the asteroid clearly, giving them more information to think about ways to stop it if it’s coming too close.
To find out the asteroid’s path, China will use supercomputers to learn about its size, shape, speed and the influence of other planets’ gravity （重力） on it. China is working on ways to change the asteroid’s path. They have ideas like sending a spaceship to hit it softly or using a spaceship’s pull to slowly change its direction.
China’s big plan shows how much it cares about protecting our planet. The scientists believe that if an asteroid does come too close, they can react in a calm and prepared way.
