阅读下面短文,根据短文内容回答问题。George is a 15-year-old middle school student. He didn't use to be interested in English. When he started taking English seriously in Grade Nine, he noticed that his grammar was a serious problem. He couldn't understand the sentences because of the grammar. To fix this, he created a study plan to improve his grammar.
He started by reviewing the basic grammar rules. He realized that he was poor in grammar because he never really understood the rules. For example, he would often mix up verb tenses(时态). To deal with this, he spent a few weeks just going over the basics. It was a little boring at first, but it made a great difference.
One of the turning points for him was when he began keeping a grammar diary. Whenever he made a mistake, he would write it down along with the correct usage. He remembers one time, he kept confusing the past perfect tense with the simple past. Writing out the differences and practicing sentences in his diary helped him internalize(内化) the rules.
After a long time of hard work, George has made great progress in grammar. Now he has a better understanding of English grammar. He can understand different tenses, parts of speech and sentence structures(结构) better. He can also find out and correct the mistakes easily. He likes English a lot now and he is sure that he will get better at English.
In fact, to get better at anything, one needs to find what one is not good at and deal with it head-on. Remember, challenges are also chances. They are chances for you to get better.
