But what exactly is infotech? 85% of the people _1_ recently had not a clue what it means, _2_53% of those polled said they thought it sounded pretty important.They were _3_.It is.So what is it? Well, put simply,it is the marry-upof products_4_several key industries:computers, telephone, televisions, satellites.It means _5_ microelectronics, telecommunication networks fibre optics_6_produce,store,obtain and send information by way of words,numbers,pictures and sound_7_and efficiency than ever before. The _8_ infotech is having and is going to have on our lives and work is tremendous.It is already linking the skills of the space industry with _9_ of cable television,so programmes can be beamed directly into our homes _10_ all over the world.

In some areas _12_the car industry this has already started. television will also be used to enable customers _13_from the comfort of their homes by simply ordering_14_ the TV screen, payment being made by direct debit of their credit cards.The automatic booking of tickets will also be done through the television_15_ .Cable television _16_in many countries now gives a choice of _17_ channels will soon be used to_18_ our homes by operating burglar and fire alarms _19_to police and fire stations.Computers will run our homes,controling the heating,air-conditioned and cooking systems _20_ robot will cope with the housework.the friendly postman will be a thing of the past as the post service and letters disappear with the electronic mail received via viewdata screens. 1) A polling B being polled C polled D having been polled2) A so B although C however D but3) A right B wrong C mad D crazy4) A from B in C to D for5) A to use B to be used C being used D using6) A to help B to helping C to be helped D to being helped7) A very quickly B more quickly C quicklier D most quickly8) A force B affect C impact D control9) A those B that C which D the one10) A from B in C across D thoughtout11) A interesting B dull C unpleasant D happy12) A for example B for instance C like D such as13) A shop B to shop C shopping D to shopping14) A on B via C within D by15) A screen B machine C set D show16) A where B in which C which D it17) A a dozen Bdozen C dozen of D dozens of18) A protect B clean C run D manage19) A related B associated C linked D joined20) A while B because C since D forcbaad abcaacdbba cdaca EXERCISE 2 The Central Problem of Economics The central problem of economics is to satisfy the peoples and nations wants. The problem we faced with is that our resources,here identified as money are _1_.The only way we can solve the problem is to _2_ choices.After looking at our resources,we must examine our list of _3_ and identify the things we need immediately , _4_ we can postpone,and those we cannot afford.As individuals,we face the central problem involved in economics-decideing how to allocate our limited resources to _5_ ourselves with greatest satisfaction of our wants. Nations face _6_ problem. As a countrys population_7_, the need for more goods and services grows correspondingly. Resources necessary to production may increase,but there _8_ are enough resources to satisfy the total desires of a nation.Whether the budget meeting is _9_ in the family living room,in the conference room of the corporation _10_ of directors,or in the chamber of the House of Representatives in Washington,the basic problem still exists.We need to find _11_ of allocating limited resources in order to satisfy unlimited wants. A short time ago,economists _12_ goods into two categories,free and economic.The former.,like air and water,were in _13_ abundance that economists had no concern for them.After all,economists is the _14_ of scarcity and what to do about it.Today many of these free goods are _15_ very expensive to use.Population has made clean air and water _16_ for producers who have to filter their waste products,for consumers who ultimately _17_ the producers extra cost,and _18_ taxpayers who pay for the governments involvement _19_ the environment.

She was born Anna Mary Robertson _5_ a farm in New York State,one of five boys and girls.(We came in bunches,_6_ radishes.) At twelve she left home and was _7_ domestic service until ,at twnety-seven,she _8_ Thomas Moses,one of the hired hands of her employers.They farms most of their _9_,first in Virginia and then in New York State,_10_ Eagle Bridge.She had ten children,of _11_ five survived; her husband died in 1927. Grandma Moses _12_ a little as a child and made embroidery pictures as a _13_, but only switched to oil in old age because her hands become too stiff _14_, and she wanted to keep busy and pass the time.Her _15_ were first sold at the local drugstore and at a fair, and were soon _16_ by a dealer who bought everything _17_ she painted.Three of the pictures were exhibition in the museum of Modern Art,and in 1940 she had her first exhibition in New York ._18_ the 1930s and her death she produced some 2000 pictures;detailed and lively portrayals of the _19_ life she had known for so long ,with a marvellous _20_ of color and form.

A shopkeeper always runs a certain _4_ when he accepts a check and he is quite _5_ his rights if,on accasion,he refuses to do so. People do not always know this and are _6_ if their good faith is called _7_. An old and very wealthy friend of mine told me he had an extremely _8_ experience.He went to a famous jewelry shop which keeps a large _9_ of precious stone and asked to _10_ some pearl necklaces.After examing several trays,he decided to buy a particularly fine string of pearls and asked _11_he could pay by check.The assistant said that this was quite _12_,but the moment my friend signed his name,he was invited into the managers office. The manager was very polite,but he explained that someone _13_ exactly the same name had presented them with a worthless check not long ago. My friend fot very angry when he heard this and said he would buy a necklace 14_.When he got up to go,the manager told him that the police would arrive at any moment and he had better stay_15_ he wanted to get into serious troubles._16_ the police arrived soon afterwards,They apologized to my friend for the _17_ but explained that a person who had used the same name as his was responsible for a number of recent robberies.Then the police asked my friend to copy out a note _18_ had been used by the theft in a number of shops.The note _19_ I have a gun in my pocket.Ask no questions and give me all the money in the safe.Fortunately,my friends handwriting was quite _20_ the thiefs.Then he was allowed to go without delay. 1) A made B replaced C instead D pretended2) A favourite B popular C profitable D convenient3) A dangerous B meaningless C unimportant D valueless4) A chance B risk C opportunity D danger5) A within B out of C without D beyond6) A unhappy B ashamed Cshocked D puzzled7) A in doubt B in earnest C in difficulty D in question8) A exciting B happy C unpleasant D wonderful9) A amount B accident C stock D number10) A give B be given C show D be shown11) A if B when C what D that12) A in need B in common C in use D in order13) A used B with C named D by14) A anywhere B somewhere C somewhere else D everywhere15) A unless B otherwise C if D whether16) A really B sure enough C certainly D however17) A manner B behavior C inconvenience D treatment18) A told B read C which D what19) A told B informed C read D wrote20) A unlike B different C dissimilar D dislikebddba aaccdabbca dccca EXERCISE 5 The meaning of time differ in different parts of the world.Thus,_1_ arise between prople from culture that _2_ time differently.

In the US,no one would _6_ of keeping a business associate _7_ for an hour.It would be too impolite,_8_ equal meet,a person who is five minutes late is ecpected _9_ a short apology._10_ he is less than five minuteslate,he _11_ say a few words of explaintion ,_12_ perhaps he will not complete the sentence. This _13_ of treating time is quite different from _14_ of several other cultures.This _15_ to explain the _16_ experience of a certain agriculturist from the United States,_17_ a duty in another country.After what seemed to him a suitable _18_ period,he _19_ that he would like to call _20_ the minister of agriculture.For various reasons the suggested time did not suit the minister;there were indirect indications that the time was not yet suitable.1) A understanding B misunderstanding C believing D belief2) A address B treat C handle D apply3) A lowly B slowly C immediately D highly4) A friends B they C others D American5) A but B yet C or else D or6) A consider B suppose C think D like7) A waiting B to wait C waited D wait8) A Since B When C While D That9) A making B to make C made D have made10) A Though B However C If D as though11) A can B will C likely D maybe12) A and B but C though D however13) A practice B process C manner D way14) A those B which C want D that15) A saves B helps C serves D aids16) A happy B fortunate C lucky D unfortunate17) A attributed B assigned C distributed D named18) A waiting B tried C waited D trying19) A announced B declare C published D reported20) A on B out C about D upbbdbd cabbcbcddb dbaaa EXERCISE 6 I have always found country life most _1_.The city ,a place _2_ business is only to _3_;it is not an an ideal place for permanent residence.People may say that the city can provide you with the best _4_ life can offer. Your friends are always _5_ for an informal chat or an evenings entertainment.The _6_ exhinitions,films or plays are always within easy reach.Shopping ,too,is always a pleasure.But what _7_ the hustle and bustle of city like? The city dweller never has a moment _8_peace;he is always_9_.And what about the noise and pollution of the city? Day and night the city is in uproar with its unceasing traffic.The air is polluted _10_ prisonous gases emitted by the smokestacks of factories.The water supply is tained with impurities that are harmful to the human body.The city is indeed not a place to live in. Country life is in many respects superior _11_ city life.For one thing , the people there are friendly.People are acquainted with one _12_.You can never _13_ receive a friendly nod or a kind word from anyone you _14_ meet.In the city people who live in the same _15_ are often strangers to one another.The air in the country is fresh and pure.Air pollution is a thing _16_ of there.You live a healthy life in the open air.Life goes on in a _17_ way and you dont have to hurry to catch _18_ bus or travel in a crowed bus with people _19_ like sardines.Gardening and fishing will be pleasant pasttimes.Reading a book _20_ the warm fireside will be another pleasant pastime on a cold winter night.Life in the country is indeed simple and pleasant.1) A enjoyable B exciting C experienced D unpleasant2) A in B on C out of D for3) A be visiting B be visited C visit D visited4) A where B when C what D who5) A wanted B wanting C available D enjoyable6) A latest B kindest C richest D poorest7) A of B about C if D should8) A for B even C once D often9) A in a moment B at the moment C in a hurry D in a line10) A in B with C of D within11) A than B to C over D for12) A another B other C what else D the others13) A expected to B want to C fail to D plan to14) A long to B be glad to C want to D chance to15) A apartment B school C room D city16) A hearing B unhearing C heard D unheard17) A leisurely B easily C conveniently D effectively18) A a B the C / D no19) A fighting B fighted C packing D packed20) A behind B by C in D onadbcc abacbbacda daadb EXERCISE 7 In addition to their academic work,children in the United States are offered a wide range of activites in the after-school hours.
