    问答题
    Practice 4　　A: What is important when...?　　Choosing a conference center　　●Facilities　　●Accommodations　　●Location　　B: What is important when...?　　Selecting an employee　　●Qualification　　●Personality　　● Creativity

    正确答案： 【参考范例】
    If you choose A:
    When choosing a conference center, it is of vital importance to consider the facilities, since facility available is the hardware component of a conference center. If the facility is in condition,, our work won’t be held up.
    Moreover, accommodation is another important matter. As a complex building, a conference center should cater to daily necessities, providing the guests with satisfactory food and bedrooms, which would leave them a pleasant recollection.
    At the same time, location is a decisive factor for business. For a conference center, company-intensive downtown area would be an ideal choice. However, there’s also a trend of moving towards tranquil suburbs.
    If you choose B:
    When selecting an employee, we should check on his or her qualification first. Certificates and diplomas can be referred to, since they reflect the extent to which the candidate receives education. However, they do not necessarily stand for a candidate’s qualification. We’ve met with too many incompetent holders of advanced degrees in real life. It is unrealistic to depend on them to make a profit for the company. On the contrary, interviewees with practical experience would bring in more benefits for the company.
    The second factor is the personality of the candidate. Everyone has a unique personality, which is a welcome phenomenon. However, a group of staff with similar personalities will meet with far less internal conflicts. Yet, there’s also a problem to worry about, since this unit might become a stagnantworking place where there is no room for vitality in the long run. Therefore, what is needed is a balance.
    Moreover, we should attach great importance to an employee’s creativity. Mediocreyesmanwho is accustomed to echoing the views of others clearly belongs to redundantlabourer. The employee is expected to have innovative ideas and be creative.
