My father became      （addict） to smoking cigarettes. As     result of smoking, he got lung cancer. And he was     danger of losing his life. His doctor didn’t allow him     (smoke) any more. My father had to take the doctor’s    (advise). As     as I know, smoking cigarettes has many other dangers to humans. Every year, a lot of people die of the illnesses or they’re      (serious) injured in fires       (cause) by smoking. And the number of people     lose their lives     (increase) at present. Therefore, I call on people to keep away from smoking.
