五、[芜湖期末]任务型阅读。
George is a 15-year-old middle school
student. He didn't use to be interested in English.
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 was useful.
Whenever he made a mistake, he would write
it down along with the correct usage (用法). He
remembered one time he kept confusing (混淆)
the past perfect tense with the simple past tense.
Writing out the differences and practicing sentences
in his diary helped him understand 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 patterns 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.
Remember, challenges are also chances. They
are chances for you to get better.
