巧学巧练系列答案Since people first sent rockets into space in the 1950s, we have been leaving behind all sorts of things. Some of them, like the camera, were lost by astronauts while they did work outside their spaceship. But much of the space junk is made up of little pieces of things that were once bigger objects, until they struck each other and broke apart.
Some things we send into space fall back toward the earth and burn up in the atmosphere. But larger pieces sometimes survive the extreme heat and hit the ground or the ocean at great speeds. So there is always concern that something may fall from the sky and do some harm.
But space junk falling on housetops (屋顶) is not the biggest worry. Scientists are concerned about what happens when an empty rocket strikes another while orbiting (绕轨道飞行) the earth. Two big things become many smaller things. They then hit other things. The pieces get smaller and smaller until they form a cloud of junk that blocks the path of future space vehicles.
So what can be done to clean up the space around our planet? Marco Castronuovo, an Italian researcher, talks about sending a satellite into space that would get very close to some of the larger pieces of space junk. The satellite would connect a small rocket to the useless object. When the rocket explodes, it pushes the junk into a lower and slower orbit, nearer the earth. After a time, the junk burns up in the atmosphere.
Mr. Castronuovo has proposed (提议) using a number of small satellites with robotic arms. One arm would catch the space junk, and another arm would connect the rocket. He imagines that each satellite would jump from one large piece of junk to another. He thinks this method could destroy about ten large objects each year.
Scientists have been concerned about space junk for many years. Right now, the costs of the clean-up have been too great. Mr. Castronuovo says his system could be put in place for a much more reasonable amount of money.

Students and Technology in the Classroom
I love my blackberry—it’s my little connection to the larger world that can go anywhere with me . I also love my laptop computer ，as it holds all of my writing and thought .Despite this love of technology ,I know that there are times when I need to move away from these device and truly communication with others.On occasion ,I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas .Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom ,I have a rule —no laptop ,ipads ,phones ,etc .When students were told my rule in advance of the class, some of them were not happy .
Most students assume that year reasons for this rule include unpleasant experiences in the past with students misusing technology . There’s a bit of truth to that.Some students assume that I am anti-technology . There’s no truth in that at all . I love technology and try to keep up with it so I relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas . I want students to think differently and make connections between the course the material and the class discussion .
I’ve been teaching my history class in this way for many years and the educations reflect student satisfaction with the environment that I create .Students realize that with deep conversation and challenge , they learn at a level that helps them keep the course material beyond the classroom .
I’m not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change ,I’m sticking to my plan. a few hours of technology-free dialogue is just too give up.
