Someday, in【C1】______the outer planets of our solar system, humankind will want to do【C2】_

Someday, in【C1】______ the outer planets of our solar system, humankind will want to do【C2】______ send small probes that merely fly rapidly by them. In time, we will want【C3】______ spacecraft that will go【C4】______ orbit around these alien planets, land robots on their moons, and even return rock and soil sample back to Earth.【C5】______ , we will want to send humans to their moons, on at least【C6】______ which liquid water—the fundamental requirementfor life【C7】______ we know it—is believed to be【C8】______ .

For missions such as these, we will need rockets powered by a nuclear reaction【C9】______ igniting chemicals. Chemical rockets have served us well. But the【C10】______ low amount of energy that they can deliver for a given mass of fuel is a severe【C11】______ when dispatching spacecraft【C12】______ long distances. To reach the outer planets, for example, a chemically-powered space vehicle must【C13】______ fuel by having a very small mass and making【C14】______ use of gravity "assists", in which the craft maneuvers close enough to a planet for the planet's gravity to propel the craft forward,【C15】______ its speed.

In technical term, chemical rockets have low【C16】______ velocity growth, which means that their exhaust velocities are not high enough to【C17】______ very high speed to the rocket. Nuclear rockets,【C18】______ their chemical counterparts, could impart a maximum velocity of【C19】______ about 22 kilometers a second. Such a high velocity would make possible a direct path to Saturn (土星), reducing travel time from about seven years to as【C20】______ as three.

For me, scientific knowledge is divided into mathematical sciences, natural sciences or sc

iences dealing with natural world, and sciences dealing with mankind. Apart from these sciences is philosophy. All this is pure or【C1】______ knowledge, sought only for the【C2】______ of understanding in order to fulfill the need to understand what is intrinsic and consubstantial (同质的) to man. What【C3】______ man from animal is that he knows and needs to know. If man did not know that the world existed, and that the【C4】______ was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldn't be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance,【C5】______ they also contribute to【C6】______ him as man and permit him to 【C7】______ a life increasingly more truly human.

【C8】______ even while enjoying the results of technical progress,【C9】______ must defend the primacy and autonomy of our knowledge. Knowledge sought【C10】______ for its practical applications will have immediate and【C11】______ success, but not the kind of important result【C12】______ revolutionary scope is in large part unforeseen, except by the imagination of the Utopians. Let me recall a well-known example. If the Greek mathematicians had not applied themselves【C13】______ investigation of conic (二次曲线) sections zealously and without the least suspicion【C14】______ it might someday be useful, it would not have been possible【C15】______ later to navigate far from shore. The first man to study the nature of electricity could not imagine that their experiments, carried on because of mere【C16】______ curiosity, would eventually lead to modern electrical technology, without which we can scarcely【C17】______ of contemporary life. Pure knowledge is valuable for its own sake, because the human spirit cannot【C18】______ itself to ignorance. But,【C19】______ it is the foundation for practical results that would not have been reached if this knowledge had not been sought【C20】______ .

Will robots take over the workforce？ And if they do, what jobs will be left for us humans？

Many discussions take a【C1】______view that the workforce will indeed be【C2】______by robots in the future—and why that is a good thing. Carl Bass, the chief executive of Autodesk, acknowledged that workplace automation has【C3】______or reduced many manufacturing jobs, and will continue to do so in the future,【C4】______major shifts in the labor market. Entire【C5】______such as trucking, will eventually be disrupted by robotic【C6】______like self-driving cars, he said. But, Bass asked: "Are the jobs【C7】______to automation ones that you would want for your children？" Few parents, he said, dreamed their kids would someday become fuel pumpers or elevator【C8】______jobs already replaced by automation. In the next 30 years, Bass added, smart machines and robots will【C9】______humans on the planet. Bass presented some【C10】______ideas to help societies deal with the structural【C11】______generated by a robot-heavy workforce, including taxing economic output rather than income, or【C12】______a "negative income tax," in which governments pay citizens a subsidy in order to【C13】______a level of income. "With our【C14】______and imagination, we will find harmony with the robots," Bass said. 【C15】______, other discussions focused on identifying jobs which were likely to remain【C16】______from robots. For example, hairdressers might be considered safe. But not because robots cant cut hair—the relationship between hairdressers and their【C17】______simply cant be robotized(And, some people might be【C18】______of a robot holding a sharp blade so close to their necks,【C19】______plenty of robots already perform. delicate surgery.) Another job【C20】______safe？ Roboticist.

Steven Weinberg is that kind of person who not only would like to help others, but really

enjoying doing so. That is【C1】______ he joined forces with his wife, Mary, and a cancer survivor Paul Young to found Hospitality for Family and Friends, Inc. The【C2】______ group helps find unsold hotel rooms for families and friends of cancer patients or for patients themselves the night before an early morning operation or【C3】______ .

"The other day we got a call from a woman who had driven all the way from Michigan to get her husband to Memorial Sloan-Kettering for treatment," said Weinberg. "She and her sons had no place to stay, so the hospital's【C4】 ______ of social work suggested they【C5】______ us. We found a room for them at last."

Since hotel【C6】______ can be very expensive, Weinberg and his volunteer staff find rooms where families can stay —free of charge of course —for one or two nights. They work with 8 hospitals and 19 hotels.

"We're【C7】______ on increasing the number of【C8】______ hotels in the New York area now, this is the place where we start our program and we have a lot of connections here", Weinberg said. "When we first started our program, we can not imagine the program is so【C9】______ now. And we hope someday we can take the program【C10】______ ."

And in these years of helping others, we come to understand more about people's needs, and those needs do not necessarily【C11】______ financial support. One time, there was a 60-year-old man calling us, asking if we could【C12】______ a room near the hospital for him to stay before his major operation. We agreed, and managed to find one room of 3-minute walking distance from the hospital. And after we【C13】______ our promise, he told us the truth.

He is a man of large means, and he can well afford to live in a【C14】______ hotel. The reason why he chose to【C15】______ us for help is that he wanted to live in a place that【C16】______ like a home. He is actually wealthy, and he has several sons and daughters, but none of them could【C17】______ him to go through the painful operation because of their busy schedule.

Since it began【C18】______ two years ago, the group has received many letters of【C19】______ . A patient from Pennsylvania wrote:" Your kind service provided me with peace of mind going into surgery【C20】______ that my wife was safe nearby."

【C1】
