Keeping a diary in English is one effective way to improve our English writing ability. Compared with other forms of writing, it is shorter and takes less time. If we persist in this practice, gradually we'll learn how to express ourselves in English. In keeping a diary in English, we inevitably come up against a lot of difficulties. In the first place, it often happens that we have trouble finding appropriate words and phrases to express ourselves. Secondly, there are many idiomatic ways of saying things in Chinese. And it is extremely hard for us to put them into English properly. Certainly, there are some other obstacles we may come across in keeping a diary in English. So I suggest we should always have a notebook and a Chinese-English dictionary within easy reach. Whenever something gets the better of us, we can first put it down in our notebook and then consult our dictionary. We can also turn to our English teacher for help, if necessary.
