Keeping a Diary in English

Our teacher asks us to keep a diary in English. I   36   doing so because I think keeping a diary in English is one of the effective ways to   37   our English writing ability.

Compared with   38   forms of writing, it is shorter and   39   less time. It can help us to   40   the habit of thinking in English.  41   we persist in(坚持) this practice, gradually we’ll learn how to express ourselves in English. In keeping a diary in English,   42   can use the important phrases and sentences we’ve   43   in or out of English classes to describe our   44  , and this way we can master and use freely   45   we’ve learned, which will do good  46  us in English learning. But   47   we certainly run up against many difficulties. In the first place, it often happens that we have   48   finding proper words and phrases to give expression to our mind. Secondly, there   49   many idiomatic (惯用的) ways of saying things in Chinese. And it is extremely hard   50   us to put them into English properly.

As far as I am concerned, my suggestion is that we   51   always have a notebook and a Chinese-English dictionary within easy reach. Whenever   52   beats(难倒) us, we can first put it down in our notebook and then look it up in our dictionary. We can also turn to our English teacher for   53  , if necessary.

In short, I believe that it is of   54   use to keep a diary in English for the development of our   55   skills.
