Below are some suggestions given by the English children posted on the website about how to help Africa. Which do you think is the best?
I think health is the most important thing. We need to make sure that the money we give is spent wisely. The money should be spent first on clean water supplies and better health care.
Robin, aged 16, Birmingham
I think the most important thing is to improve the education of the African countries. There is an old saying,  "If you give a man a fish, you'll feed him for a day. If you teach him how to fish, you'll feed him for a lifetime." We need to help themselves, not just throw money at the problem when it appears.
Rebecca, aged 15, Liverpool
People seem to give a lot more money to charity when there is a sudden, huge disaster(灾难)like the earthquake. It's good for people to do so, but I also think that everyone should give a small part of their salary(工资)to charity. If everyone did that, it would make a big difference.
Mary, aged 14, Stratford-on-Avon
Giving money to charity can help, but it's not the final answer. I think what these countries need is a good government.
Bethany, aged 16, Newcastle
The best thing we can do is to send experts(专家)like engineers, doctors and teachers to help the people to help themselves.
Robert, aged 16, Cardiff
