　　Suggested answers to Exercise 2：

　　1 Even when he was a young man，he knew how important it was to produce bigger rice crops.

　　5 It does not cost anything to dream for something.

　　Suggested answers to Exercise 3：

　　1 Yuan Longping wanted to increase the rice output because he saw many people go hungry when he was young.

　　2 I think he is more of a scientist，although he works in the fields like a farmer.His main purpose is not to make a profit for himself but to study agriculture and use that knowledge to improve farming for farmers everywhere.I do not think he is a business man，because his goal is not to make money.

　　3 Because of his work with developing hybrid rice，it seems that Yuan Longping must be a very patient and careful man.He didn't give up but kept working on his project.He also seems to use his invention to help hungry people around the world.

　　4 I think Yuan Longping was successful because he kept working and did not give up.He also grew up in a poor family，so he was very motivated to succeed and help other farmers around China.

　　5 I mostly agree.I think being rich can cause a lot of problems，but it really depends on the life and attitude of the person who is rich.People who are rich certainly have different problems from people who are not.

6 I think developing other hybrid grains would make a great difference in the problem of world hunger.Hybrid grains that can survive in very dry or very hot areas would be very useful in Africa
