  一、代词


  关系代词


  1. 含义:
  主从句中引导从句的关系代词,起到连接主从句作用,并作一定的句子成分。


  2. 用法:
  (1)who指代人,作主语。
  例如:
  Tom is a student who studies SAT.(who指代主句的a student,在从句中作主语。)
  (2)whose指代人,意思是“谁的”,相当于形容词,后加名词一起作主语。
  例如:
  There are two books. Whose book is this?(whose+book作从句的主语。)
  (3)whom指代人,作宾语。
  例如:
  The company hired two graduates, both of whom are from China.(both of whom指代graduates,whom在介词of之后,在从句中作宾语。)
  (4)which指代物,作主语。
  例如:
  Qingdao is the place which has issued a red rainstorm warning.(which指代主句的the place,在从句中作主语。)
  (5)that指代人或物,作主语或宾语。
  例如:
  Mary bought a hat that is fashionable.(that指代主句的a hat,在从句中作主语)

  A. NO CHANGE
  B. which holds
  C. this holds
