Let's write a composition
Dear students,
In some parts of our country, there are many children out of school. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Thanks for your joining!

参考答案：
Because their family can't afford to send them to school.
At the same time, children don't have enough money to buy school
things and clothes.
can/cant't afford to do sth:付得起/付不起做某事。
用上连词at the same time,表达贫困学生另一个问题。
In my opinion, each child should have the right to go to school，
接下来写自己的想法。
but there are few chances for them.
引出教育不公平。
So we should try our best to do something to help them，
just like giving them school things, clothes and so on.
to help them 动词不定式表目的状语。
举一个例子，捐物。
We believe if we work together, we can make a better future for them.
最后一个要点作为最后一段总结全文。
