Important words:1. how often, how long，how soon，how many times（1）how often意为“多久一次”，是对在某段时间内进行某个动作的次数提问，答语通常是never，sometimes，often等表示频率的副词或短语，常用于一般现在时或一般过去时中。如：-How often do you go to the movies? -Once a week.（2）how long意为“多久，多长时间”，是对一段时间提问，答语通常是（for）+段时间的短语，可用于各种时态。如：-How long did you live here？- For ten years.（3）how soon意为“还要多久”是对从某个基本时间到将来某个动作结束或发生的这段时间提问，答语通常用“in+一段时间”，常用于一般将来时中。如：-How soon will you get there？-In half an hour.（4）how many times意为“多少次”，它最易与how often混淆。how many times既不询问时间，也不询问单位时间内动作发生的频率，只询问次数，常对once，twice等词提问。如：-How many times did you go to Shanghai?- Four times.2. exercise “锻炼，运动”（1）动词，相当于do sports。如： You should exercise every day to keep healthy.（2）名词，做不可数名词时意为“锻炼，运动”，表示为了健康而进行的体格方面的锻炼或运动，常与take，do 连用。如：If you dont take / do more exercise youll get fat.（3）做可数名词时表示身体各部位的训练以及各种技能技巧的训练或“体操，典礼”等，意为“训练，练习”通常用复数形式。如：We do morning exercises every day. 我们每天做早操。3. hardly，hard 副词hardly“几乎不，几乎没有”表示否定意义，它通常位于实意动词之前，系动词、助动词或情态动词之后。句中有hardly就已经表示否定了，不再使用其他否定词。短语hardly ever“几乎不，几乎没有”如：It hardly rains here.hard 既可以做形容词又可作副词，hard做形容词时意为“困难的，硬的，勤奋的”作副词时意为“努力地，刻苦地，猛烈地，剧烈地”The problem is too hard to answer.They worked hard to finish it on time.4. ever“曾，曾经”多用于疑问句、否定句及现在完成时中。如： Have you ever been to London? 5. time名词，做可数名词时意为“次，次数”一次用once，两次用twice，三次或以上用数词 + times。如：-How many times do you watch TV a week？time还可以做不可数名词，意为“时间”What time is it?【拓展】some time，sometime，some times， sometimes（1）some time指“一段时间”常与for 连用。这里的time为不可数名词“时间”如：It will take me some time to walk there.（2）sometime副词“某个时候”，可以指过去或将来的某个时候，用于过去或将来时中，也可以指过去或将来不明确的某个时间。如：We will go on vacation some time.（3）some times“几次，几倍”其中的time为可数名词。如：We have been to Beijing some times.（4）sometimes频率副词“有时”用于一般现在时中，可用于句首、句中或句末。如：He sometimes goes to the movies on Sunday.II.
