Insights from reading

Read the text aloud quickly and think about what aspects the text mainly talks about? Outline the sentences in the article that involve astronomical knowledge.

The text mainly talks about the legend of the Milky Way and some other stars; the story of the Cowherd and the Weaver Girl; the introduction of Altair and the Star Vega as well as other astronomical knowledge.

Vega is 50 times as bright as the Sun, and Altair is more than 9 times as bright as the Sun. Just because they are too far away from us, they appear to be just two larger planets.

Vega is 26 light years away from the earth, and Altair is 16 light years away.

The author uses two sets of numbers to illustrate the brightness of Vega and Altair and the distance to the earth, and makes a comparison. The explanation method of listing numbers and making comparisons makes things that were unclear immediately become clear.
