I hope you are very well(　　　　　 ). I'm fine, but tired(　　　　 ). Right now it is the summer vacation and I'm helping my Dad on the farm(　　　　 ). August is the hottest month here(　　　　 ). It is the time of year for the rice harvest, so every day I work from dawn until dark.(　　　　 ) Sometimes we go on working after dark by the lights of our tractors(　　　　　　　 ). We grow rice in the south of the States, but in the north where it is colder they grow wheat(　　　　 ). We have a lot of machines on the farm(　　　 　　　 ). Although the farm is large, my Dad has only two men working for him(　　　　 ). But he employs more men for the harvest(　　　　　 ). My brother takes care of the vegetable garden(　　　　　 ). It doesn't often rain in the summer here(　　　　　　 ). As a result, we have to water the vegetable garden(　　　　　 ). Every evening we pump water from a well(　　　　　　　 ). It then runs along channels to different parts of the garden(　　　　 ).

Most Saturday evenings there is a party, even at harvest time(　　　　 ). These parties often make us very happy(　　　　　　 ). We cook meat on an open fire outside(　　　　　　 ). It's great(　　　　　　　 )! Americans eat a lot of meat - too much in my opinion(　　　　　 ). Some of my friends drink beer(　　　　　 ). I don't, because I have to drive home after the party(　　　　 ). In your letter you asked about the time in different areas of the States(　　　　 ). There are five different time areas in the States(　　　　 ). In my state we are fourteen hours behind Beijing time(　　　　　 ). How many different time areas do you have in China(　　　 　　　 )? Well, I must stop and get some sleep(　　　　 ). Please give my best regards to your parents(　　　　　　　 ).
