Actually,  2  , most people make several job choices during their working lives,  3   because of economic and industrial changes and partly to improve their position.

Young people should  5   enters into a broad flexible training program that will  6   them for a field of work rather than for a single  7 .　　Unfortunately many young people have to make career plans  8  benefit of help from an  9   vocational counselor or psychologist. Knowing  10   about the occupational world, or themselves for that matter, they choose their lifework on a hit-or-miss basis. Some  11   from job to job. Others  12   to work in which they are unhappy and for which they are not fitted.　　One common mistake is choosing an occupation for  13   real or imagined prestige. Too many high-school students-or their parents for them-choose the professional field,  14   both the relatively small proportion of workers in the professions and the extremely high educational and personal  15  . The imagined or real prestige of a profession or a white-collar job is no good  16   for choosing it as life’s work.  17  , these occupations are not always well-paid, since a large  18   of jobs are in mechanical and manual work.

    正确答案： 1.D  考点:名词辨析。文章首句指出本文的主题是career(职业),所填词应与career意思相近,故答案为D项occupation职业。identification认同。entertainment娱乐。accommodation膳宿。
    2.A  考点:逻辑关系。联系上下文,在高中选课之前职业方向就应该确定,然而很多人都是在工作生活中才考虑这个问题。前后意思有转折,故答案为A项however然而。
    3.C  考点:副词辨析。分析句子结构,and连接了两个表并列关系的原因,由于后半部分出现了partly,因此前半部分也应填入partly,与之对应对应,故答案为C项partly。entirely全部地。mainly主要地。possibly可能地。
    4.D  考点:动词辨析。结合上文,大多数人在一生的工作中要选择几种工作,由此可推断出,一份完美的工作根本不存在,故答案为D项exist存在。fade消失;凋谢。vanish消失。survive幸存。
    5.B  考点:逻辑关系。结合上下文,一份完美的工作不存在,所以人们要参加灵活的培训项目以便有更多的择业机会,由此可知,前后为因果关系,故答案为B项therefore所以。since和for作连词时也表因果,但其后接原因,而不是结果。furthermore此外,而且。
    6.B  考点:固定搭配。fit sb. for sth.为固定搭配,意为“使某人适合做某事”,故答案为B项。
    7.A  考点:名词辨析。文中a single  7   与a field of work对应,空中所填词与work意思相近,A项job是work的近义词,故答案为A项job。
    8.C  考点:介词辨析。根据本句第一个单词Unfortunately可判断,所填单词的意思是否定的,故答案为C项without。这句话的意思是“他们的职业规划没有得到职业顾问或心理专家的帮助”。
    9.A  考点:形容词辨析。分析句子结构,此处所填词作定语,修饰vocational counselor or psychologist (职业顾问或职业心理专家)。结合选项及句意,答案为A项competent有能力的,能胜任的。competitive有竞争力的。aggressive 有进取心的。effective 有效率的。
    10.A  考点:副词辨析。根据句末的hit-or-miss(无计划的,无目的的)可判断出,年轻人们对occupational world的了解不多。故答案为A项little。
    11.B  考点:动词搭配。由空后的from可知,本空所填词能与from搭配使用,只有B项drift符合条件,drift from work to work指不断换工作,故答案为B项。
    12.C  考点:动词搭配。结合句意,本句和上句在意思上应该相反。另一些人即使工作不适合他们,也不换工作,故答案为C项stick。stick to意为“坚持”。apply与to连用表示“应用到…”。appeal与to连用,意为“呼吁:对…有吸引力”。turn与to连用,意为“求助于,转向”。
    13.B  考点:逻辑关系。结合句意,空格处要填的词指代前面的an occupation,故用代词its,答案为B项its。
    14.D  考点:动词辨析。结合句意可知,许多高中生或家长选择专业领域,不是职业从业人员较少就是专业要求较高,因此是盲目地选择。故答案为D项disregarding漠视,忽视。concerning关注。following遵循。considering考虑。
    15.B  考点:名词辨析。所填词能被high修饰,表示专业工作的实际情况,故答案为B项requirements要求。此处是说这些工作对教育水平和个人要求很高。preferences偏好。tendencies倾向。ambitions雄心。
    16.C  考点:名词辨析。此处是说工作的声望好并不是选择工作作为终身职业的好理由。故答案为C项reason理由。
    17.D  考点:逻辑关系。本句是对上句的进一步说明,“而且这些工作不一定报酬都很高”,故答案为表递进的D项Moreover此外。
    18.C  考点:名词辨析。thickness和density均可以与of连用,分别表示“…的厚度/浓度,”和“…的密度”,但二者不与a搭配使用。rate表示“比率”时常用high/low修饰,且构成at a rate of这一固定搭配时,表示“以…的速度”,与语境不符。proportion常构成a proportion of这一结构,表示“…的部分”,在本文中表示很大一部分工作,故答案为C项。
    19.A  考点:固定搭配。作者在提醒年轻人,当然提醒的是大多数人,而不是少部分人,故答案为A项majority大多数。minimum意为最少量。minority少数。multitude不能同时与of和the连用,a multitude of sb./sth.意为“多数,大批”,或the multitude(s),表示“群众,大众”。
    20.C  考点:名词辨析。结合句意可知,这里应该是说提醒年轻人认真考虑此事,故答案为C项consideration考虑,顾虑。proposal提议,建议。suggestion建议。appraisal评价,鉴定。

    An operating system also has to be able to service peripheral（ ）,such as timers,motors,sensors,communicationdevices,disks,etc.All of those can request the attention of the OS（ ）,i.e.at the time that they want to use the OS,theOS has to make sure it's ready to service the requests.Such a request for attention is called an interrupt.There are twokinds of interrupts:Hardware interrupts and Software interrupts.The result of an inteiTup:is also a triggering of theprocessor,so that it jumps to a（ ）address.Examples of cases where software interrupts appear are perhaps a divide by zero,a memory segmentation fault,etc.So this kind of interrupt is not caused by a hardware event but by a specificmachine language operation code.Many systems have more than one hardware interrupt line,and the hardwaremanufacturer typically assembles all these interrupt lines in an interrupt（请作答此空）.An Interrupt（ ）is a piece of hardware that shields the OS from the electronic details of the interrupt lines,so that interrupts can be queued and none of themgets lost.
