B2 First (FCE) >> Gapped Text Reading Worksheets >> The second part of the B2 First Reading section is gapped text - a single page of text with some numbered gaps which represent missing sentences. After the text there are some sentences which are not in the right order. Students have to read the text and the sentences and decide which sentence best fits each gap. This is a short article, Space Junk.

Gapped Text Reading 7
In the following text, five sentences or parts of sentences have been removed. Below the extract you will find the five removed sentences PLUS one sentence which doesn't fit. Choose from the sentences (A-F) the one which fits each gap (1-5). Remember, there is one extra sentence you do not need to use.
Space Junk
There is an ever increasing number of objects in low Earth orbit. A camera, a glove, a hand tool, even a toothbrush: they are all up there, above the clouds, going around and around the Earth. There are also thousands of pieces of metal and plastic. Some of them are only about the size of a fingernail. (1)________________________ Scientists consider all these objects to be "space junk," and they are a problem.
Since people first launched rockets into space in the nineteen-fifties, 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 spacecraft. (2)________________________
Some things we send into space fall back toward 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 is not the biggest worry. Scientists are concerned about the "Kessler" syndrome. It is named for the American scientist who first thought of the idea in 1978. Imagine what happens when an empty rocket strikes another while orbiting the earth. (3)________________________ 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 Space Agency researcher, has an idea. In the publication "Acta Astronautica," he writes about launching 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. (4)________________________
Mr. Castronuovo has proposed 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. (5)________________________ Mr. Castronuovo says his system could be put in place for a much more reasonable amount of money.

Choose from the following sentences to fill the spaces in the text. There is one extra.
- Two big things become many smaller things.
- After a time, the junk burns up in the atmosphere.
- Though costly, it would in time create a much safer space environment for all space-faring nations.
- Right now, the costs of the clean-up have been too great.
- 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.
- Many are much larger.
