听力原文：Woman: Good morning, Susan Logistic Company.
Man: Good morning. This is Tom Scavo, from Vaness Company. I'm colling concerning the packing of the goods.
Woman: Do you have any special requirements？
Man: I'd like to know your outer packing. I think it must be strong seaworthy packing.
Woman: We plan to use corrugated cardboard boxes. T-shirts will be packed 15 dozen to one carton, gross weight around 20 kilos. Ladies' pajamas will be packed 20 dozen to one carton, gross weight around 25 kilos.
Man: I'm afraid cardboard boxes are not strong enough for transport by sea. Will such outer packing be strong enough to withstand the handling during ocean transportation？ Why don't you use wooden case instead？
Woman: Cartons are comparatively light and easy to handle, and they will not be stowed away with heavy cargo. The stevedores know that. Besides, we will reinforce the boxes with straps and line them with plastic sheets. The goods you ordered are not fragile, and they can stand jolting.
Man: You know, cartons are easy to be cut open. Wooden cases are much stronger than cartons.
Woman: Don't worry about that. Up until now, we have not received any complaints about our packing. Furthermore, such packing is approved by our insurance company.
Man: In this case. I agree with you to use cardboard boxes for the outer packing.

Escaping from the Earth
The Earth has a force that pulls things toward itself. We call this force gravity(地心引力). This is something we live with all the time, and we take it for granted and hardly ever think about it. But it is a most important factor in rocket operation and must be overcome if we are to get anywhere in space, or off the ground at all.
Take the throwing of a ball as an example. The harder the ball is thrown, the faster and higher it will go. What is the secret？ Its speed. If we could throw the ball hard enough it would go up and up forever and never come down. The speed at which it would have to be thrown to do this is known as escape speed. Of course, we cannot throw a ball hard enough because the speed required to escape completely from the Earth's gravity is seven miles per second, or over twenty-five thousand miles per hour.
Once escape speed has been reached by a spacecraft(宇宙飞船), no further power is needed. A rocket aimed at the Moon, for instance, will "coast"(滑行) the rest of the way because the Earth's gravity cannot then pull it back, and there is no air resistance(阻力) in space to slow it down. This "coasting" is known as "free fall". That does not mean the rocket is falling down towards the Earth but that it is traveling freely in space without the aid of power, like a bicycle coasting downhill.
Free fall is an important feature of space travel: it would be impossible to carry enough fuel to provide powered flight all the time.
What is the most important factor for a rocket to escape from the Earth？
A．To travel as fast as it can.
B．To overcome the Earth gravity.
C．To get away from the air resistance.
D．To have strong power in its operation.
