title: 一道英语选择题Weneedfifteenmorepeople__ 
desc: We ne fifteen more people _____our team to do the job.
  A but                 B except              C as well                D besides   
  选出正确答案,写明以上四个词的具体用法,愈详细愈好.
answer: 个人认为应该是D.从fifteen more可以看出还要人手,而:
  besides除了...之外还包括...
  except除了...之外(不包括...在内)
  but通常和否定词连用,如nothing等.
  as well 倒不如, 还是...的好 
  最好...还是(It will be As well to stop that young screamer. 但是最好还是让那个大哭大叫的孩子住声。) 在这儿意思不合适.
