第一句两句之间有逗号的话要连词，可以用because。第二句expo开头要大写，最好前面加个2010，同样和后面的句子要有连词，可用and。30 minutes前要加个for， I believe if I pay a hard, I will be rewarded表达有点怪，别的语法错误到没有，就是文章层次跳得太快了
My favorite subject is English,because it is a useful and interesting language.With the 2010 World Expo drawing near, English is certain to be very useful then,as it can help us communicate with foreign guests.Now,in order to improve my English level,I read English 30 for minutes every day.. Also,at school, the teacher will help us to learn new words and explain the English text,and I always listen to
my teacher carefully .What's more, I often do adequent amounts of English exercises to improve my grammar.As the saying goes: no pains, no gains. I believe if I keep working hard both at school and at home,I will have a good commmand of English when the Expo arrive.
