标题: 中考考点例析:How long
拓展How long主要用于对一段时间的提问,意为“多长时间”,该句型中的动词具有延续性动特点;此外,该句型也可以提问某物“多长”。例:
How long have you lived here?你住在这里多久了?
How long is the stick? 这根棍子有多长?
辨析How long/How often/ How far/How soon
    How long意为“多长时间”或“(某物)多长”;How often意为“多久一次”,用于对频度副词或短语的提问How far意为“(路程)有多远”,用于对距离的提问;How soon意为“还要多久”,用于将来时态中对“in +一段时间”的提问。
考例
1.Maria and Jane have waited at the airport for two hours.(对画线部分提问)
_______ _______ have Maria and Jane waited at the airport?
2. --_______ will you stay in Shenzhen for your holiday?
  --For about two weeks.
  A. How often    B. How long    C. How soon    D. What time
点睛】根据答语可知是对一段时间的提问,要用how long。故选B
