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!
