    Passage 2How to Pick a Career in Business　　Picking the right career in business is a matter of matching what you want to do with, the kind of life you want to lead. Figuring (31)______ how to strike this balance generally requires prioritizing the following issues: industry, location, and working conditions. Fist and foremost, ask yourself what industry interests you (32)______? Many websites on the Internet can be (33)______ great use. For example, Vault corn provides a thorough list of industries that can give you the information necessary for (34)______ this decision. It is also important to investigate what kind of business careers in your target industry (35)______ growing and hiring. Location involves many factors. Where would you like to live? Do you prefer big cities or small towns? How far and by what (36)______ are you willing to commute? Do you want to be close to your family and friends (37)______ do you want to strike out into new territory? Many people also (38)______ into account the cost of living in different areas of the country or world. Then (39)______ the question: what kind of working environment best suits your working style? Some people need to feel rooted to a workspace (40)______ they are surrounded by co-workers, while others hope to see new faces every day. When choosing your career in business, try to consider which way—or in which combination—you are most comfortable and productive.

    正确答案： 31. OUT
    此题考查动词短语figure out, 表示“想出,理解”。
    32. MOST
    对本空格所在的句子分析可知,宾语从句中结构完整,主语、谓语、宾语齐全,因此可以推断空格处所缺的是修饰动词interests的程度副词来。根据逻辑关系,填入most意思是“对……最感兴趣”。
    33. OF
    be of+n. =adj.这一句型的用法是本题考查的关键点,此处的be of great use, 与be very useful的意思相同。
    34. MAKING
    此空格处需要填入一个动词与decision搭配形成动宾关系。短语make the decision意为“做决定”,另外,动名词应该跟在介词for后面,所以空格处应填making。
    35. ARE
    what引导的内容是本空格所在的句子的宾语从句,其中此处需要填入的是be动词与其后的“growing and hiring”形成现在进行时态。此外,根据主谓一致关系,“business careers”为本从句的主语,所以答案为are。
    36. MEANS
    理解commute的含义是本题解题的关键,它的意思是“通勤,往来于工作地点和住所之间”。所以此空格所缺的是表示交通方式的单词。此外,means of transportation意为“交通方式”,因此答案为means。
    37. OR
    空格的前后句都是独立的简单句,所以空格处所缺的是能够连接这两个简单句的并列连词以便构成一个并列句。所以填入or连接两个简单疑问句构成一个选择疑问句。 短语strike out意为“开始独立生活或创业”。
    38. TAKE
    固定搭配take into account的意思是“考虑”。
    39. COMES
    空格所在的句子为一个倒装句, 空格处所需要填入的是谓语动词。此处的come意为“来临,到来”。
    40. WHERE
    本空格填人的关系代词where引导定语从句修饰先行词workspace。
