Read the title and the text quickly. Where would you find an article like this
Reaching for the Stars
Identifying the text type
Before you read, decide what kind of text it is. Is it a sci-fi story, popular science article, news report, or something else
Since the beginning of human history, people have looked up at the stars and wondered what they were like.Many ancient cultures believed that these points of light were from gods or other mysterious worlds.However, as science and technology developed, we learnt the truth about stars. They are real places like our own sun,and they are farther away than anyone imagined.This raises the question: Can we visit the stars one day
The man-made object which has travelled farthest from Earth is Voyager 1. This spacecraft was launched in 1977.In case Voyager 1 is found by alien life, a special record with sounds and pictures from Earth is carried on board.It shows who we are and where we are from. By 2025,Voyager 1 was over 25 billion kilometres from Earth, but that is still a long way from Earth's second-closest star,Proxima Centauri. That star is 4.2 light years away-about 40 trillion kilometres!
In popular science magazines or online science news websites.
The challenge of visiting the stars gets even bigger for space flights with humans. The farthest that any human has travelled in space is only about 400,000 kilometres,to the far side of the moon.Time is a big problem.At present,even a journey to the planet Mars will take around six to nine months.What will the
astronauts eat and drink during this period And how about their health and safety
These problems grow when we talk about visiting another star.It might take hundreds of thousands of years to get there!
Scientists, however, believe that visiting the stars is not a completely wild dream. One idea is to have the astronauts sleep during their journey, like some animals do in winter. Another is to develop much faster spacecraft.While this is not possible right now, with nations and scientists cooperating with one another, there is hope that the necessary technology will be developed. Humans have photographed other galaxies, set foot on the moon, and even successfully landed rovers on Mars. It seems likely that one day we will reach the stars.
1c
Paragraph 1 A.Long distance space travel is difficult for humans.
Paragraph 2 B.Humans have long been curious about the stars.
Paragraph 3 C.In the future,it may be possible to visit a star.
Paragraph 4 D.No spacecraft has travelled close to a star.
Read again and match each paragraph with its main idea.

Discuss the questions. Find more information to support your answers.
We've read about humans' dream to visit the stars. Let's recall: What's the main question of the text (Can we visit the stars one day )
Let’s discuss four questions about space exploration. You can use facts from the text and your own ideas to answer them.
1.What did some ancient cultures think about the stars Why
2.What is carried on board by Voyager 1 Why
3.What is the farthest trip that a human has travelled from Earth Do you know
any details about it
4.What do you think about the future of space exploration
Group work
Here are some basic sentence patterns you can use to answer questions.
问题类型 基础句型
事实类（What） From the text, we know that... / It says in the passage that...
原因类（Why） Because... / That's why...
观点类（What do you think） I think... / In my opinion,... / I believe that...
Work in groups of four. Read the questions silently and think on your own. Underline the key information for each question in the text, and write down the key words.
Discuss the questions in your group and answer the four questions one by one.
Each group chooses one or two questions and shares its answers. Then the class comments on the answers.
1.What did some ancient cultures think about the stars Why
2.What is carried on board by Voyager 1 Why
They thought the stars were from gods or other mysterious worlds. Because they didn’t have modern science to learn the truth about stars.
A special record with sounds and pictures from Earth is carried on board Voyager 1. Because scientists hope if aliens find it, they can know who we are and where we are from.
Sample
3.What is the farthest trip that a human has taken from Earth Do you know any details about it
4.What do you think about the future of space exploration
The farthest human trip in space was to the far side of the moon, about 400,000 kilometres from Earth. American astronauts went there in the 1960s and 1970s.
I think space exploration will develop fast in the future. With new technology and international cooperation, humans may visit Mars or even other stars one day.
