听力原文： The great advance in rocket theory 40 years ago showed that liquid-fuel rockets were far superior in every respect to the skyrocket with its weak solid fuel, the only kind of rocket then known. However, during the last decade, large solid-fuel rockets with solid fuels about as powerful as liquid fuels have made their appearance, and it is a favorite layman's question to inquire which one is "better". The question is meaningless; one might as well as ask whether a gasoline or a diesel engine is "better". It all depends on the purpose. A liquid-fuel rocket is complicated, but has the advantage that it can be controlled beautifully. The burning of the rocket engine can be stopped completely; it can be reignited when desired. A solid-fuel rocket, on the other hand, is rather simple in construction, though hard, to build when a really large size is desired. But once you have a solid-fuel rocket, it is ready for action at a very short notice. A liquid-fuel rocket has to be fueled first and can not be held in readiness if or very long after it has been fueled. However, once a solid-fuel rocket has been ignited, it will keep burning. It can't be stopped and reignited whenever desired. Because a solid-fuel rocket can be kept ready for a long time, most military missiles employ solid fuels, but manned space flight needs the fine adjustments that can only be provided by liquid-fuel rocket. It may be added that a liquid-fuel rocket is an expensive device; a large solid-fund rocket is, by comparison, cheap.

听力原文： Isaac Singer was an inventor. Life is easy because of his invention. His story begins in 1811. He is born poor. He is the eighth child of a German immigrant. At age 22, he runs away from home and become an actor. An actor does not make much money, so Isaac also learns to be a mechanic. When he needs money, he works as a mechanic.
Now it is 1851. Singer is working as a mechanic in Boston. Someone tells him he can make a lot of money if he can make a good sewing machine. Singer needs money. There are already several kinds of sewing machines. But none of them work well. In eleven days, Singer makes the first sewing machine that really works.
Singer and two other people stag the I. M. Singer Company. They make sewing machines. Soon everyone wants to buy one. The singer Company uses a great new idea to sell its machines. People do not have to pay all the money at one time. They can pay a little money every month or every week.
The sewing machine changes life in the United States. Woman do not have to sew clothes for the family. For the first time, people can buy ready-made clothes and shoes.
Isaac Singer became a very, very wealthy man. He stops work and retires. He builds a house with 115 rooms in England. When he dies, his 24 children fight over his money.

I made a pledge to myself on the way down to the vacation beach cottage. For two weeks I would try to be a loving husband and father. Totally loving. No ifs, ands or buts.
The idea had come to me as I listened to a talk on my car radio. The speaker was quoting a Biblical(圣经的) passage about husbands being thoughtful of their wives. Then he went on to say, "Love is an act of will. A person can choose to love." To myself, I had to admit that I had been a selfish husband. Well, for two weeks that would change.
And it did. Right from the moment I kissed Evelyn at the door and said, "That new yellow sweater looks great on you.
"Oh, Tom, you noticed," she said, surprised and pleased. Maybe a little puzzled.
After the long drive, I wanted to sit and read. Evelyn suggested a walk on the beach. I started to refuse, but then I thought, "Evelyn's been alone here with the kids all week and now she wants to be alone with me." We walked on the beach while the children flew their kites.
So it went. Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate museums. Relaxed and happy, that' s how the whole vacation passed. I made a new pledge to keep on remembering to choose love.
There was one thing that went wrong with my experiment, however. Evelyn and I still laugh about it today. On the last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression.
"What s the matter. I asked her.
"Tom," she said in a voice filled with distress, "do you know something I don't？"
"What do you mean？"
"Well... that checkup(体检) I had several weeks ago.., our doctor.., did he tell you something about me？ Tom, you’ve been so good to me... am I dying？"
It took a moment for it all to sink in. Then I burst out laughing.
"No, honey," I said, wrapping her in my arms. "You' re not dying; I' m just starting to live."
In the first paragraph, "No ifs, ands or buts" probably means"______."
