Keeping a diary in English is one of the useful ways     1     can improve our English writing ability. Compared with other forms of writing, it is     2    (short) and takes less time. It can help us to develop the habit of thinking in English. If we keep     3    (try) this practice, gradually we’ll learn how to express ourselves in English.

In keeping a diary in English, we     4    (certain) run up against many difficulties. In the first place, it often happens that we have difficulty     5    (find) exact words and phrases to express our mind. Secondly, there are many idiomatic ways of saying things in Chinese. And it is extremely hard for     6    (we) to put them into English properly.

My     7    (propose) is that we should always have a notebook and a Chinese-English dictionary     8     easy reach. Whenever something     9    (trouble) us, we can first put it down in our notebook and then refer to our dictionary. When necessary, we can also turn to our English teacher for help. In short, I believe that it is     10     effective way to keep a diary in English for the development of our writing skills.

Nowadays, there is a growing concern over the issue of students' smoking.

As is known to us all, smoking may have all kinds of harmful     1     (effect) on the health of both the smokers themselves and non-smokers around them. For example, smoking does terrible damage to smokers’ hearts and lungs and it is more difficult for smoking couples to become pregnant.

Once they start smoking, they may find     2    difficult to quit because they can become physically addicted     3     nicotine and may develop the habit of smoking and finally become mentally addicted.

So, it is high time that these young smokers made up their minds to quit smoking. Firstly, they are supposed to prepare     4     (they). For example, they can make a list of the benefits they will get from stopping smoking. Then throw away the last packet of cigarettes. Secondly, be determined. Every time they feel like    5    (smoke)a cigarette, remind themselves that they are non-smokers. Reread the list of benefits they wrote     6     (early). Thirdly, every time they feel stressed, they can do some relaxation exercises     7     do something else to keep their minds and especially their hands busy. Finally, do not be     8     (disappoint) if they have to try several times before they finally stop smoking. Just try again and they will succeed     9    (eventual).

I wish that all the students    10     (can) get rid of smoking.
