Complete the text with the verbs in brackets. use "would + v" or the past tense. what would happen if i drilled a tunnel through the center of the earth and jumped into it? it would be impossible to do this on earth because it is too hot, but you could do it on the moon. imagine a tunnel through
the moon. if you (jump) into the tunnel, you (accelerate) toward the center at a very high speed because of gravity. then you (go) through the center and start slowing down. then, when you (reach) the end of the tunnel on the other side of the moon, you (stop), and then you (fall) back down in
the tunnel in the other direction. you (go) backwards and forwards like this forever!
