B
To make a further space exploration, scientists sent James Webb Space Telescope(詹姆斯·韦伯空间望远镜) into space in 2021. It is the largest and most powerful telescope, as tall as a three-floor building. It is much bigger than Hubble Space Telescope(哈勃空间望远镜), the first space telescope.
The James Webb Space Telescope is made up of 18 mirrors. It "sees" by collecting light with its mirrors. The main mirror of it is 6.5 meters wide. The bigger the mirrors are, the farther it can see. It can "see" infrared(红外线) light. This helps it "see" stars over 13.6 billion light years away. In fact, the faraway(遥远的) stars that it "sees" are ancient. That's because the light from the stars takes time to travel in space. For example, a star gave off light billions of years ago. The light then traveled for billions of years to reach us.
What can James Webb Space Telescope do? It can learn about how galaxies(星系) were formed and take pictures in our solar system. It can also study the planets outside our solar system.
May James Webb Space Telescope be burned(燃烧) by the hot sun? Don't worry. It has a sunshield(遮阳板) to protect itself from the sun's heat.

6. A 由第一段第二、三句可知，James Webb Space Telescope有三层楼那么高，比Hubble Space Telescope大得多，故可从本段了解它的大小。
7. C 由第二段第二句可知，James Webb Space Telescope通过用镜子收集光来观测。
8. D 由第四段最后一句可知，遮阳板可以遮挡太阳的热。
9. D 由第三段第二句可知，它可以了解星系是如何形成的，还能在太阳系中拍照。
10. B 通读文章可知，本篇文章主要介绍James Webb Space Telescope是如何观测太空的。

【分析】
做这类阅读理解题，需先明确题目对应的段落，再定位原文关键信息，逐一比对选项排除错误项，选出与原文一致的答案。比如第6题锁定第一段找望远镜的相关描述；第7题定位第二段找观测方式；第8题定位第四段找遮阳板功能；第9题结合多段细节判断正误；第10题通读全文概括主旨。
【解析】
6. 定位第一段，文中提到詹姆斯·韦伯空间望远镜“as tall as a three-floor building”（和三层楼一样高）、“much bigger than Hubble Space Telescope”（比哈勃空间望远镜大得多），这些均属于其大小（size）的描述，因此选A。
7. 定位第二段第二句“It 'sees' by collecting light with its mirrors.”，明确其通过镜子收集光来观测，对应选项C。
8. 定位第四段最后一句“It has a sunshield to protect itself from the sun's heat.”，可知遮阳板的作用是保护望远镜免受太阳热量影响，对应选项D。
9. 定位第三段第二句“It can learn about how galaxies were formed and take pictures in our solar system.”，可知韦伯望远镜可在太阳系中拍摄行星照片，D选项正确；A选项错误，遥远恒星的光需时间传播，并非一发出就被收集；B选项错误，观测到的是恒星过去的样子；C选项错误，它还能研究系外行星。
10. 通读全文，文章主要介绍詹姆斯·韦伯空间望远镜的构造、观测方式、功能等，核心是它作为观测太空的工具，对应选项B。
