Weight on and off the Earth We are so used to.our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted.Because we can feel that things are heavy,we think of "weight"as being a fixed quality in an object,but it is not really fixed at all.If you could take a one-pound packet of butter 4,000 miles out from the earth,it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space?The reason is this:all objects have a natural attraction for all other objects;this is called gravitational attraction.But this power of attraction between two obects gets weaker as they get farther apart.When the butter was at the surface of the earth,it was 4,000 miles from the center.When we took the butter 4,000 miles out,it was 8,000 miles from the center,which is twice the distance.If you double the distance between two objects,their gravitational attraction decreases two times two.If you treble the distance, it gets nine times weaker(three times three)and so on. So this is one of the first things we need to remember that the weight of an object in space is not the same as its weight on the surface of the earth. What about the weight of our pound of butter on the surface of the moon?At the distance the puii of the earth is about 4,000 times smaller than it is here on the surface,so we can forget all about the earth-pull on our butter. On the other hand,on the moon there will be an attraction between the butter and the moon,but the butter will weigh only about one-sixth as much as it does on the earth.This is because the moon is so much smaller than the earth.The amount of gravitational pull that a body produces depends on the amount of material in it.A packet of butter has a gravitational pull of its own;but this is very small in relation to the pull of something as large as the moon,or the earth,or the sun.According to the passage,"weight"should be understood in the sense thatA:it is fixed if it is outside the earth's gravitational puliB:it decreases four times when it is 4,000 miles from the earth's centerC:it varies with the change of the gravitational attraction between two objectsD:things increase in amount as they are closer to the earth's surface

单选题An American manufacturer of space heaters reported a 1994 fourth-quarter net income (total income minus total costs) of $41 million, compared with $28.3 million in the fourth quarter of 1993. This increase was realized despite a drop in U.S. domestic retail sales of space-heating units toward the end of the fourth quarter of 1994 as a result of unusually high temperatures. Which of the following, if true, would contribute most to an explanation of the increase in the manufacturer’s net income?A
In the fourth quarter of 1994, the manufacturer paid its assembly-line workers no salaries in November or December because of a two-month-long strike, but the company had a sufficient stock of space-heating units on hand to supply its distributors.B
In 1993, because of unusually cold weather in the Northeast, the federal government authorized the diversion of emergency funding for purchasing space-heating units to be used in the hardest. hit areas.C
Foreign manufacturers of space heaters reported improved fourth-quarter sales in the American market compared with their sales in 1993.D
During the fourth quarter of 1994, the manufacturer announced that it would introduce an extra-high-capacity space heater in the following quarter.E
In the third quarter of 1994, a leading consumer magazine advocated space heaters as a cost-effective way to heat spaces of less than 100 square feet.
