点一下不认识的单词。
Scientists use the James Webb Space Telescope to study small rocky planets far from Earth. These planets orbit small stars called M stars. The telescope helps scientists learn if these planets have thick atmospheres like Venus or if they are bare rocks.
Most of these rocky planets do not have thick atmospheres. This means the telescope can study their surface properties by measuring thermal emission, or heat coming from the planets. This helps scientists learn about the geology of planets outside our solar system.
Some small rocky planets called lava worlds are very hot. Their surfaces can melt. Scientists study these lava worlds to understand their atmospheres. The James Webb Space Telescope looks at ten lava worlds in a survey called LAVALAMPS.
Scientists also study how lava worlds reflect light. They find that lava worlds are more reflective than very dark hot planets called hot Jupiters. This new information helps us understand the origins of atmospheres on different planets.

难句解析
- 1
This means the telescope can study their surface properties by measuring thermal emission, or heat coming from the planets.
难点在于“by measuring thermal emission, or heat coming from the planets”。“by doing”表示“通过做某事”；“thermal emission”后用“or”解释为“heat coming from the planets”，即“来自行星的热量”。整句意思是：这意味着望远镜可以通过测量来自行星的热量来研究它们的表面特性。
- 2
They find that lava worlds are more reflective than very dark hot planets called hot Jupiters.
难点在于“called hot Jupiters”是修饰“very dark hot planets”的定语从句，意思是“被称为热木星的非常黑暗的热行星”。整句意思是：他们发现熔岩世界比那些被称为热木星的非常黑暗的热行星更能反射光。
- 3
This new information helps us understand the origins of atmospheres on different planets.
难点在于“the origins of atmospheres on different planets”，这里“origins”指“起源”，“on different planets”修饰“atmospheres”。整句意思是：这些新信息帮助我们了解不同行星大气的起源。
本篇语法
一般现在时 (Present simple)
一般现在时表示习惯、经常发生的事和事实：I drink tea every morning. 主语是 he / she / it 或单数名词时，动词要加 -s 或 -es：She works. He watches TV. 否定和疑问用 do / does：I don't like coffee. Does he live here?
I / you / we / they + verb · he / she / it + verb-s
故事中的例句
- Scientists use the James Webb Space Telescope to study small rocky planets far from Earth.
- These planets orbit small stars called M stars.
- The telescope helps scientists learn if these planets have thick atmospheres like Venus or if they are bare rocks.
常见错误
第三人称单数忘记加 -s（中文动词没有变化）。
She work in a bank.
She works in a bank.
