Teaching Aims
Read the article written by a father for a newspaper. What is his family going to sell at the yard sale
My children are growing up fast. My daughter is 16 and my boy is already in junior high school. As they get bigger, our house seems to get smaller. So we want to sell some of our things in a yard sale and give the money to a children's home.
We have already cleared out a lot of things from our bedrooms. We have decided to each sell five things that we no longer use. My son was quite sad at first. Although he has not played with his old toys for a long time, he still wanted to keep them. For example, he has

owned a train and railway set since his fourth birthday, and he played with it almost every week until he was about seven. And he did not want to lose his toy monkey, either. He slept next to the monkey every night when he was a child. My daughter was more understanding, although she also felt sad to part with certain toys.
As for me, I did not want to give up my football shirts, but, to be honest, I have not played for a while now. I am getting older, too!

（1）for后须接“时间段”

（2）since后须接“时间点”
He has studied English since 1999.
他从1999年开始学英语。

for + 一段时间 = since + 一段时间 + ago
He has been here for five weeks.
= He has been here since five weeks ago.
他到这儿已经有五个星期了。

He has taught here since he came to China.
自从他来到中国就在这儿教书。
We have been friends since we met in school.
我们从在学校见面起就成为了好朋友。
（5）现在完成时常用句型：
It is (has been) +时间段+ since +时间状语或从句
It is four days since last Friday.
从上周五到现在已经四天了。
