[简答题]We all know that we should take better care of ourselves, relax more, and have more fun at work (and elsewhere, as well) , but it’s easy to overlook the opportunities to do just that be cause of the daily work priorities that consume our lives. Here are some ideas for learning to take action in your work life.

[单项选择]We all know that programming language is the system of syntax, grammar, and symbols or words used to give instructions to a computer. Because computers work with binary numbers, first-generation languages, called machine languages, required the writing of long strings of binary numbers to represent such operations as add, subtract, and compare. Later improvements allowed octal, decimal, or hexadecimal representation of binary strings. It is difficult to write error-free programs in machine language; many languages have been created to make programming easier and faster. Symbolic, or assembly, languages-- second-generation languages-- were introduced in the early 1950s. They use simple mnemonics such as "A" for add or "M" for multiply, which are translated into machine language by a computer program called an assembler. An extension of such a language is the macro instruction, a mnemonic (such as "READ") for which the assembler substitutes a series of simpler mnemonics. In the mid-1950s
A. it is used in designing software.
B. it is hardware-independent.
C. is should be translated into the computer language by software.
D. it is designed to solve some specific problem.

We all know that a magician does not really depend on "magic" to perform his tricks. He depends on his ability to act at great speed. However, this does not prevent us from enjoying watching a magician produce rabbits from a hat, swallow countless eggs, or saw his wife in two.
Probably the greatest magician of all time was Harry Houdini who died in 1926. His real name was Ehrich Weiss. He adopted the name "Houdini" after reading a book written by the famous magician called Robert Houdin.
Houdini mastered the art of escaping. He could free himself from the tightest knots or the most complicated locks. Although no one really knows how he did this, there is no doubt that he had made a close study of every type of lock ever invented. He would carry a small steel needle-like tool strapped to his leg and he used this in place of a key.
Houdini once asked the Chicago police to lock him in prison. They bound him up, but he freed himself in an i
A. Robert Houdin gave him the name.
B. A magician often uses "magic".
C. Someone will saw his wife in two.
D. Houdini studied knots and locks.

[单项选择]We all know that it is possible for ordinary people to make their homes on the equator (赤道), although often they may feel uncomfortably hot there. Millions do it. But as for the North Pole (北极)--we know that it is not only a dangerously cold place, but that people like you and me would find it quite impossible to live there. At the present time only the scientists and explorers can do so, and they use special equipment. Men had been traveling across and around the equator on wheels, on their feet or in ships for thousands of years; but only a few men, with great difficulty and in very recent time, have ever crossed the ice to the North Pole. So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator. Of course, this is not true about landings in the polar region (which passenger aeroplanes do not make), but the weather, if we are flying at a height of 5000 meters above the Pole, is a delight. At 4 000 meters and More
A. feeling uncomfortably hot on the equator
B. flying over the North Pole
C. flying over the equator
D. making homes on the equator

We all know that science plays an important role in the societies in which we live. Many people believe, however, that our progress depends on two aspects of science. The first of which is the machines, products and systems of applied knowledge that scientists and technologists develop. Through technology, science improves that structure of society and helps man to gain increasing control over his environment. 61) The second aspect is the application by all members of society from the government official to the ordinary citizen, of the special methods of thought and action that scientists use in their work.
62) Human beings have distinguished themselves from other animals, and in doing so ensured their survival, by the ability to observe and understand their environment and then either to adapt to that environment or to control and adapt it to their own needs. The process of careful observation, perception of a pattern in the phenomena observed, followed by
