四．点拨总结
1. --How long have you had that bike there?
--I have had it for three years
辨析：how long, how soon, how often, how far
How long 多久，多长（时间）。对时间段提问，如：for+时间段；since+过去的时间点。
e.g. --How long have you worked in Beijing?
--For five years.
How soon 多久以后。对“in+时间段提问，常用于一般将来时”，其答语常用“in+时间段”。
e.g. –How soon will Mr. Li be back?
--In a week.
How often 多久一次，对频率提问，其答语为：once（twice/…）+时间段，always，usually等。
e.g. --How often do you exercise?
-- Once a day.
How far 多远，对距离提问，其答语是表距离的内容。
e.g. --How far is it from here to your school?
-- Three kilometers.
辨析：for 与since
for其后只能接表示“一段时间”的名词性短语，可用于多种时态，表示动作或状态持续时间段长短。
e.g. I have lived in this city for five years. 我在这座城市居住了5年了。
He usually sleeps for twelve hours every day. 他通常每天睡12个小时。
since 其后接表示“时间点”的短语或从句（过去时），也可以接“一段时间+ago”，常用于完成时态；还用于句型：“It is +时间段+since+一般过去时的句子”。表示过去某个时间发生并持续到说话时的动作或状态。
e.g. It is two years since I came to China. 自从我到中国以来已经两年了。
She has worked here for five years. =She has worked here since five years ago.
她在这儿工作5年了。
2. Jeff’s family is having a yard sale.
sale用作名词，意为“出售，销售”，on sale意为“出售，上市”；for sale意为“待售，供出售”，尤指从主人手里出售。
e.g. Chickens are on sale in the market.
小鸡在市场上出售。
I’m sorry, it’s not for sale.
抱歉，它不出售。
3. Amy thinks it’s hard to sell her old things.
艾米认为卖掉她的旧东西很难。
It’s +adj. (+for sb.) to do sth. 意为“（对某人来说）做某事时……的”，it 是形式主语，真正主语是后面的动词不定式。
e.g. It’s important for un to learn English well.
学好英语对于我们来说是很重要的。
4. Amy wants to keep her old things because they bring back sweet memories.
艾米想保留她的旧东西，因为它们勾起她的甜蜜回忆。
memory n. ，意为“记忆；回忆”，复数形式为memories，动词为memorize，意为“记忆，背诵”。
e.g. She has a good memory. 她记忆力好。
5. I’ve had this magazine for a couple of months. 这本杂志我买了几个月了。
a couple of 表示具体的数量“两个”，指两个相同的人或物体; 表示数量不定的“少数几个”，作这种虚指的用法时，具体意思往往视上下文和具体的语境而决定，例如：
You have to wait for a couple of hours for the clothes to dry completely.
你得等上一两个小时让这些衣服完全晾干。
6. The stories inside may be a bit old, but they’re still interesting.
a bit 意为“一点儿，稍微”，修饰形容词或副词，相当于 a little；
a bit of +不可数名词，a little直接加不可数名词。
e.g. There is a bit of/a little water in the bottle.
瓶子里有点儿水。
not a bit =not at all 意为“一点也不”
not a little =very 意为“非常”
e,g. She is not a bit happy. 她一点儿也不快乐。
He is not a little tired.=He is very tired. 他非常累。
7. And check out these soft toys and board games for younger kids.
check用作及物动词，意为“检查，审查”，短语check out，意为“察看，观察”。
e.g. If you finish it，check it by yourself first.
如果你完成了，就自己先检查一下。
Check out all the books for children.
察看一下所有的儿童书籍。
check 还可用作名词，意为“支票。账单”
