Read the following passage and then choose the most suitable word for each space.

Technology

           When faced with some new and possibly bewildering technological change, most people react in one of two ……….(1). They either recoil from anything new, claiming that it is unnecessary, or too complicated or that it somehow makes life less than ……….(2). Or they learn to …………(3) to the new invention, and eventually………..(4) how they could possibly have existed without it. Take computers as an example. For many of us, they still represent a ……….(5) to our freedom, and give us a frightening sense of a future in which all ……….(6) will be taken by machines. This may be because they seem mysterious, and diffcult to understand. Ask most people what you can use  a home computer for, and you usually get ……….(7) answers about how ‘they give you information’. In fact, even those of us who are familiar with computers, and use them in our daily work, have very little idea of how they work. But it does not take long to learn how to operate a business programme, even if things occasionally go wrong for no apparent reason. Presumably much the same happened when the telephone and the television became ……….(8). What seems to alarm most people is the speed of technological change, rather than change itself. And the ……….(9) that are made to new technology may well have a point to them, since change is not always an improvement. As discover during power cuts, there is a lot to be said for the oil lamp, the coal fire, and forms of entertainment, such as books or board games, that don’t have to be ………..(10) in to work.


Câu 58:

There is ten mistakes in  following sentences. Find and correct them.

           My cousin and her husband lived in one of the suburbs of London. One morning they woke up to find at  their dismay that their car had been stolen from outside their house. They immediately phoned the police to report the thief before left for work by bus.

           When they returned home later the same day, they found that their car brought back and was parked in its common place outside their house. Under one of the windscreen wiper was a small envelope.

           They quickly opened it and found a note to apologize profusely for "borrowing" their car. The man who wrote it explained that he didn't have the car itself, and his wife had gone into labour in the middle of the night with their first baby. So he hoped they wouldn't mind too much that he had taken their cars without their permission in order to run her to the hospital as it was anything of an emergency.

Read the article about endangered species. For questions 1-10, choose the correct answer A, B, C or D. 

         The word laser was coined as an acronym for Light Amplification by the Stimulated Emission of Radiation. Ordinary light, from the Sun or a light bulb, is emitted spontaneously, when atoms or molecules get rid of excess energy by themselves, with out any outside intervention. Stimulated emission is different because it occurs when an atom or molecule holding onto excess energy has been stimulates to emit it as light

         Albert Einstein was the first to suggest the existence of stimulated emission in a paper published in 1917. However, for many years physicists thought that atoms and molecules always were much more likely to emit light spontaneously and that stimulates emission thus always would be much weaker. It was not until after the Second World War that physicists began trying to make stimulated emission dominate. They sought ways by which one stomp or molecule could stimulate many others to emit light, amplifying it to much higher powers.

         The first to succeed was Charles H. Townes, then at Columbia University in New York. Instead of working with light, however, he worked with microwaves, which have a much longer wavelength, and built a device ha called a “maser,” for Microwave Amplification by the Stimulated Emission of Radiation. Although he thought of the key idea in 1951, the first maser was not complete until a couple of years later. Before long, many other physicists were building masers and trying to discover how to produce stimulated emission at even shorted wavelengths.

         The key concepts emerged about 1957. Townes and Arthur Schawlow, then at Bell Telephone Laboratories, wrote a long paper outlining the conditions needed to amplify stimulated emission of visible light waves. At about the same time, similar ideas crystallized in the mind if Gordon Gould, then a 37-years-old graduate student at Columbia, who wrote them down in a series of notebook. Townes and Schawlow published their ideas in a scientific journal, Physical Review Letters, but Gould files a patent application. Three decades later, people still argue about who deserved the credit for the concept of the laser.

The word “coined” in line I could best be replaced by _________
