人民警察与剥削阶级国家警察的区别在于( )。

A.维护的阶级利益不同

B.专政对象不同

C.专政的目的不同

D.与人民群众的关系不同

答案

参考答案:A,B,C,D

解析: 人民警察与剥削阶级国家警察的区别如下。①维护的阶级利益不同。人民警察是维护工人阶级和广大人民群众最根本、最长远利益的,因而其宗旨是全心全意为人民服务。剥削阶级警察是维护剥削阶级利益的,为剥削阶级的金钱所雇用,成为剥削阶级的打手。②专政对象不同。人民警察代表广大人民群众向敌对势力和一切敌视社会主义制度和人民民主专政 * * 、破坏社会主义现代化建设的敌对分子实行专政。这种专政是大多数人对极少数人的专政。剥削阶级警察的专政对象是无产阶级和其他劳动人民群众,是剥削者极少数人对大多数劳动人民的专政。③专政目的不同,人民警察所代表的人民民主专政目的是为了巩固社会主义制度,促进社会生产力的发展,加快社会主义建设,提高人民的物质和文化生活水平,乃至最终消灭剥削制度,消灭阶级压迫,实现 * * 主义,因而这种专政是革命的专政。剥削阶级警察所代表的剥削阶级专政的目的是维护剥削阶级的私有制,维护剥削阶级的政治统治。④与群众的关系不同。人民警察是全心全意为人民服务的,他们是人民的公仆和忠诚的卫士,因而得到群众的信赖和支持。剥削阶级警察是压迫人民的工具,所以他们与广大人民群众是对立的。他们为了缓和同人民群众的尖锐矛盾,也要做一些为公众服务的事,但这仅仅是将此作为一种统治手段和策略,归根结底还是为了维护剥削阶级的政治统治,同人民警察全心全意为人民服务的宗旨有着本质的区别。故选ABCD。

填空题

The following is a text about the perpetual motion machine. In the paragraphs with numbers, the supporting details, data or facts have been omitted and are listed following the text in random order. Match each of the details with the statement it supports.
Perpetual Motion Machine is a fascinating and long-discussed topic that moves well beyond the scope of physics. In short, a perpetual motion machine can be likened to a magic cow that continues to live and breathe and yet needs no sustenance. A perpetual motion engine installed in a car would continue to run indefinitely but would need neither gas tank nor petrol. Of course, as a perpetual motion machine is in violation of natural laws, it will likely never move out of the realm of imagination and into reality. When the phrase " perpetual motion machine " is entered into Google’s search engine, 34,400 items are returned. Of these 34,400 items, the forty-first to the forty-fifth hold reasonable interest and will be further discussed herein.
41. Myths and legends
Long before the advent of the steam engine, human beings have ruminated on the possibility of a perpetual motion machine. Throughout history, many have attempted to invent such a device, though none have thus far been successful.
42. Fame and glory
Some people hold that any inventor attempting to create a perpetual motion machine must only be in it for credit and accolades, wishing to be the first in his field to discover the much-coveted secret.
43. Wealth and riches
It is also suspected by some that those seeking to unlock the mystery of perpetual motion machine must be motivated by the monetary rewards. If such a device were to fall into popular use, the inventor would be a wealthy man indeed.
44. Antics and capers
Even some of those who are aware of the impossibility of perpetual motion machine have invented something similar under the guise of perpetual motion machine in order to tease us.
45. Deception and trickery
Some people, though fully aware that they are incapable of inventing a perpetual motion machine, persist in arguing that they can with the intention of scamming us.
Though the perpetual motion machine is a dream long-sought after by the scientific community, it is improbable that it will ever be realized. We can, however, pour our resources into researching more practical energy conserving forms of power such as geothermal, hydro-electric, and solar power solutions.
[A] Inventor K declared, " The experiments with perpetual motion are on the verge of success. My products will soon be distributed throughout the world and used in a wide range of industrial applications. When that happens, my company will expand exponentially. I’ll make a fortune! "
[B] Inventor F told me excitedly, " Some complex details are currently under discussion to unearth the key to perpetual motion. If my experiment proves to be effectual, I will become a Nobel Prize winner. You know, the ceremony is held annually in Sweden and is broadcasted live to every corner of the globe. " It is no great wonder that Inventor F espoused enthusiasm. A functional perpetual motion machine is a wonder that would be marveled at for generations to come.
[C] In ancient China there was an extremely adroit man by the name of Zhu Geliang. It is said that he constructed a wooden horse which could walk unaided and could be used in the transportation of military supplies. As no records of this occurrence have been found, this tale has passed into legend.
[D] One of the closest things to a perpetual motion engine was the one installed on the Traveler 1 spacecraft, the first spaceship in human history to fly beyond the edges of our solar system. Though Traveler’s engine is able to Fun without maintenance for many years, it still requires energy—nuclear energy. So, strictly speaking, Traveler 1 does not run on a perpetual motion engine, but in fact needs energy as do all other machines.
[E] Mr, Goofy announced that he had effectively diagrammed the first perpetual motion machine. When a private corporate party purchased the patent, they found to their dismay that manufacturing it according to the design layout was technically infeasible. Furious, they sued Mr. Goofy for fraud, but even in the courtroom, Mr. Goofy would not be shamed. He simply retorted, " I’m just joking around. "
[F] Tom, proudly proclaiming that he had invented a clock that ran on perpetual motion, and had it placed in the central square of his town. The clock, he said, would work perfectly despite a lack of springs in the internal mechanism. A scientist later ascertained the secret and revealed it to the townspeople: the clock had been cleverly devised to run on temperature differentials.
