They are putting too much carbon dioxide into the atmosphere, which prevents heat from (31)_________(escape) from the earth into space.As a result (32)____ this, many scientists believe the earth may become too hot to live on.

I might even grow taller if I stay here long enough. I shall certainly weigh less!” I laughed and climbed down the (14)______(step) from the spaceship. But (15)______ I tried to step forward, I found I was carried twice as far as on the earth and fell over. “Oh dear,”I cried, “(16)______(walk) does need a bit of practice now that gravity has changed.” After a while I got the hang of (17)_____ and we began to enjoy ourselves.
