【题目】 Ned and Miles are students at different colleges. Ned applies for an online school, while Miles attends classes on a school campus. The two students each believe that their school system is better than the other.

Ned: Hey, Miles. Are you free to see a movie tomorrow night?

Miles: Sorry, no. I’ll have a class tomorrow and a lot of homework to finish up.

Ned: Oh, that’s too bad. I’m so glad I take classes online. I can decide when, where and how to complete my lessons. It saves a lot of time.

Miles: It sounds good, but I actually really enjoy going to class because it’s a great way to get to know other people. It also helps me learn how to work well with others. If I don’t understand something, I’m always able to ask about it in person. That saves me a lot of time and prevents misunderstanding.

Ned: In an online class, I have to think thoroughly (彻底地) before asking questions. That teaches me how to solve problems on my own.

Miles: Do you ever run into technical (技术上的) problems in your online classes? If you can’t open a file, how can you continue your learning?

Ned: It’s not a big problem. I can email the teacher or contact another student for help.

Miles: But answering questions through emails takes too much time. You may fall behind on your studies.

Ned: You can fall behind, too. What if you get sick or your class gets canceled because the weather is bad? Those aren’t problems for online classes.

Miles: Yes, but there’s usually a make-up (弥补) class if a class is canceled.

Ned: In an online class, I don’t have to worry about missing classes for any reason. I can always review the previous (之前的) lessons online.

Miles: Don’t you feel lonely sometimes? I would feel lonely if I had to learn on my own.

Ned: I’m confident in learning by myself. Besides, an online class gives me more free time to take part in other activities.

Miles: I still prefer having classmates to brainstorm and discuss ideas with. I believe that improves my learning all the time.

Ned: I’m pretty self-disciplined (自律的), and I work better on my own. I can’t focus when working with others.

Miles: I guess everybody learn differently.

【题目】 Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.

According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.

Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle (交通工具).

To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

"The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.

"The time to act is now. The longer we leave the problem, the bigger it will become," he says.

1Junk has become a problem in ________ too.

2What would happen if the tiniest piece of junk crashed into a spaceship?
