Text presentation
It’s Saturday afternoon. Jenny and Brian go to visit Danny. When they arrive, Danny is outside in the yard.
Brian：Hi Danny. What do you have there
Danny：It’s a telescope. I told my father that we were studying the solar system. He said that I could use his telescope. (He looks through the telescope.) That’s funny! I can see only a tiny circle of light.
Jenny：(She laughs.) You’re looking through the wrong end, Danny! Try looking through the other end.
(Danny turns the telescope around and looks through it again. )
Danny：That’s better! But I still can’t see any stars or planets.
Brian：You certainly can’t, Danny! The sun is shining. The stars come out at night.
Jenny：The sunset today is around 7: 00 p. m. Maybe Brian and I can join you after supper. I would love to look through your telescope.
Danny：Great. You two can help me.
Brian：Help you What are you trying to do
Danny：I want to discover a new planet.
Brian：I don’t think you can find one unless you have a bigger telescope. Scientists use huge telescopes when they look for planets.
Danny：Bigger than mine
Jenny：Bigger than your whole house! Actually, double the size of your house!
Danny：Well, it’s worth a try, even if I don't find a planet.
Brian：We can try tonight. The universe is a mystery. Maybe we’ll find other amazing things!
