阅读下面的短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项。
On February 21, 2022, US company SpaceX sent 46 satellites into space. Then six days later, China sent 22 satellites into space. Why do we need so many satellites? What do they do for us?
At present, there are more than 3,000 active satellites moving around the earth. Satellites have all kinds of roles, from sending TV signals, giving you directions on the road, to helping scientists with their research. For example, the 22 satellites China sent up are part of the BeiDou Navigation(导航) Satellite System. Shared bikes that use Beidou chips can provide more correct positions, making them easier to find.
Before the use of satellites, TV signals didn't reach very far. Mountains or tall buildings would block the signals. Phone calls to faraway places were also a problem. Setting up telephone wires over long distances is difficult. With satellites, TV signals and phone calls can be sent directly to a satellite and back down to different places on the earth. SpaceX's Starlink project plans to use satellites to provide people with the internet all over the world.
Satellites can also provide information about clouds, oceans, land and ice. They help scientists with predictions of changes in weather and climate. By watching and checking wildfires and volcanoes(火山), satellites help emergency workers deal with natural disasters. Farmers can use satellite pictures to decide the best time to water their fields.
Some satellites fly near other planets. They may look for water on Mars or take close-up pictures of Saturn's(土星的) rings. One video website even sent a satellite into space to look at other planets and share pictures and videos with users.

解析：
【解析】
1. 细节理解题：根据第一段"On February 21, 2022, US company SpaceX sent 46 satellites into space. Then six days later, China sent 22 satellites into space."，2月21日加6天为2月27日，对应选项D。
2. 词义猜测题：根据第三段"Before the use of satellites, TV signals didn't reach very far. Mountains or tall buildings would block the signals."，卫星使用前电视信号传输距离有限，山和高楼会阻碍信号传播，block含义为“阻挡、阻止”，对应选项C。
3. 细节判断题：根据第二段"At present, there are more than 3,000 active satellites moving around the earth."可知A表述正确；B选项文中仅说明中国发射的22颗卫星是北斗系统的一部分，并非北斗系统总共只有22颗，表述错误；C选项帮助科学家预测天气气候，卫星协助应急人员应对自然灾害，表述混淆错误；D选项卫星使用前长途通话是难题，并非容易，表述错误。
4. 篇章结构题：第一段通过发射卫星的事件引出问题“卫星能为我们做什么”，是总起段；第二到第五段分别从不同方面介绍卫星的各类作用，属于分述内容，整体结构为①/②③④⑤，对应选项C。
5. 主旨大意题：全文围绕卫星的各类功能展开，开篇就抛出核心问题"What do they do for us?"，对应最佳标题为选项B。
