小行星或在2032年撞击地球？

Scientists found an asteroid (小行星) called 2024 YR4. It is big. It might come near Earth in 2032. But the chance of it hitting Earth is small, only 0.28%.   ▲   — it will likely miss our planet!

Scientists watch the asteroid carefully. They learn more about it. If needed, they can try to push it away. Scientists will keep watching it until May, 2025. After that, they can not see it again until 2028.

1.The asteroid 2024 YR4 is __________

A small

B long

C big

D

解析：选C。细节理解题。根据第一段中的“It is big.”可知，小行星很大。故选 C。

2.Which can be put in the “ ▲ ”?

A Don’t worry

B Be careful

C Help us

D

解析：选A。推理判断题。前一句说撞击概率只有0.28%，并结合后一句“it will likely miss our planet”它可能撞不到我们的星球，可推断作者说“不要担心”。故选 A。

3.The scientists can ________ if the asteroid gets too close.

A break it

B push it away

C let it hit Earth

D

解析：选B。细节理解题。根据第二段中的“If needed, they can try to push it away.”可知，科学家可以试着把它推开。故选B。

4.The scientists can’t see 2024 YR4 in ________.

A 2025

B 2026

C 2028

D

解析：选B。推理判断题。根据第二段最后两句“Scientists will keep watching it until May, 2025. After that, they can not see it again until 2028.”可知，他们要到2028年才能再次看到它，因此2025年5月后至2028年之前科学家看不到这颗小行星。由此可知在2026年科学家们看不见它。故选B。
