the world are filled with fear and use their computers with care.some may even choose not to turn on their computers on march 3rd.all this fear and care are just because a deadly computer virus(病毒) is ready to cause damages on that day.whats a computer virus then？why do people get so afraid of it?a computer virus is，in fact，a little program that is put into other programs and that does something bad.it is called a virus because，like any reallife viruses such as aids virus(艾滋病毒)，it reproduces(繁殖) itself.and when these programs are run，the virus is brought to life.it hides itself in your computer system waiting for the right moment to make damages.and at the same time it keeps producing itself by copying itself onto other programs.the michelangelo virus waits until the artists birthday comes around，and then it will wake up to do very bad things like destroying your files.so next time when you turn on your computer，look out for computer viruses!1the italian artist

that you have got what you want，you should learn to make good use of it.(2)since you have got everything that you want，you should learn to use it well.(3)as youve gained everything you want，you shouldnt waste it. 答案.1.have been built2.has been received3.has；been cleaned4.has been collected5.has been repaired 6has；been published7.hasnt been painted 8has been taken.1.d句意为：每年大量农民工涌入深圳，去寻找他们离乡前别人给他们许诺的挣钱的工作。此处农民工是“被许诺工作”，需用被动语态，故排除a、c两项；b项仅表一般过去时的被动；d项表示“已经被许诺”，符合语境，故选d。2b句意为：他的妹妹自从1998年离开家后一直杳无音讯。根据句意，指从1998年后到现在一直没有音讯，故应用现在完成时，排除a、c两项；又因他的妹妹和hear of之间是被动关系，故排除d项。3d由题干可知，湖水现在散发着臭味，用现在完成时态说明结果，故选d。4dthey指代的是english songs，与teach构成被动关系，从many times可知强调完成，所以用现在完成时的被动语态。5a由语境可知咖啡是“被喝光了”，这是已经发生的事实，对现在有影响，所以要用现在完成时的被动语态。6btake place是不及物动词短语，不用于被动语态，排除a、d两项；set up与factories为动宾关系，排除c项。7d由句意可知，该空应该用现在完成时的被动语态。8d由时间状语for a long time可知到说话时为止很长时间没有见到邮递员了，且see与postman之间为动宾关系，故用现在完成时的被动语态，所以选d项。9c时间状语so far意为“到目前为止”，常用于现在完成时，suggestions与give之间是被动关系，故应用被动语态，所以选c。10awhen and where通常作为一个整体，作主语时，谓语动词用单数形式；decide与when and where之间为动宾关系，再结合yet可知此处用现在完成时的被动语态。11bemploy与you为动宾关系，再结合答语since 2002可知此处应用现在完成时的被动语态。12a句意为：在南方竹子被用来建房子有上千年的历史了。use与bamboo之间为动宾关系，故应用被动语态，又由时间状语for thousands of years可知，应用现在完成时被动语态。故选a项。13d由时间状语up to now可知应用现在完成时。另外，主语means与try之间为被动关系，故用被动语态。means为单复数同形的单词，由其前的every可知此处作单数名词，故选d项。14c由order与dessert的动宾关系可知应用被动语态，排除a项。由“thats too bad.”可知，甜点已经被订，故选c。15d根据“how many times”可知动作发生在一段时间内，故应用完成时态。tell与you之间为动宾关系，故d项正确。.1.(1)the child has been given some interesting books.(2)some interesting books have been given to the child.2the machine has been repaired (by him)
