There are several ways improve our English writing kills, such as keeping a diary, learning some good writings with heart, doing a lot of reading, ect. As for me, I prefer keeping a diary. Comparing with other forms of writing, keeping a diary is easier and take less time. Beside, it can help us form the habit of thinking in English. If we can keep this practice, and we will gradually learn how to express us in English. What’s more, keeping a diary can be like talking about one of our close friend, sharing our happiness or sadness. In the word, keeping a diary is a good way of improving our written English.
