Unit 6 How long have you been collecting shells？重难点解析1. How long have you been in class today?你们今天上了多长时间的课？（1）how long 意为“多久”。
如：How long are you staying in Hong Kong?你将在某某呆多久？How long did you do your homework?你做作业做了多久了？（2）how 的相关词组:how much 多少（钱）how many 多少how far多远how often 多久一次how old多大how soon 多久以后注：how much 可对不可数名词的数量进行提问；还可对价格提问。
how many 提问可数名词的数量。
2.A:Alison，how long have you been skating?艾丽森，你滑冰已经多长时间了？B:I have been skating for five hours.我已经滑了五个小时。
for表示时间的持续，后面加时间段，表示一段时间，多与带数词的名词连用，其谓语需用延续性动词。
We have been learning English for two years.我们学英语已经两年了。
I slept for eight hours last night.我昨晚睡了八个小时。
注：在现在完成时中，若动词为非延续性动词，与for短语连用时，要转换为延续性动词。
例如：borrow—keep；buy—have；arrive—be here；e back—be back；get up—be updie—be dead；begin—be on3. since表示“自从过去某一时间点以来”，后面接点时间，强调动作或状态一直延续到现在，一般用现在完成时或现在完成进行时。
例如：I have been skating since eight o’clock.自从八点开始，我就已经滑冰了。
