Many adults and children die from it--it's called secondhand smoke. It comes from the smoke that is breathed out by a smoker, as well as the smoke that comes from the end of burning cigarette. It's almost as lethal as smoking a cigarette. 　　Secondhand smoke contains over 4 000 chemicals, and of those, 200 are poisonous（有毒的）and 43 can cause cancer. It causes about 3 000 lung（肺）cancer deaths and 35 000 heart disease deaths to non-smokers each year. Some of the many chemicals breathed in are lead, formaldehyde (a poisonous, colorless gas), benzene (colorless liquid from oil) and ammonia (a smell gas). 　　Every time someone lights a cigarette near you, you are being forced to breathe in all those chemicals. You can get a number of diseases--many incurable（不能治愈的）--from secondhand smoke, but it is especially dangerous for children. It is estimated that secondhand smoke is responsible for between 150 000 and 300 000 lower respiratory（呼吸的）tract（消化系统）infections（感染）in young children and because of this, between 7 500 and 15 000 children are hospitalized each year. So if you smoke, try to give up! Otherwise, avoid smoky areas and breathe fresh air. (1)The passage is written to tell us ________.
