Every year, almost 2 million Americans are injured while they're 　1 work. Every day, 240 are killed on the job. The 　2　 job is cutting down trees. Being a policeman is safer than many jobs, including driving a truck, collecting garbage and 　3 airplanes. One of the safest jobs is being a librarian.

The government inspects(检查) most factories and offices. 4 have to 　5 fines if their factories or offices are unsafe. In California, employers often go to prison if one of their workers is 　6 because a factory didn't 　7 　safety measures. But President Bush cut down the number of government inspectors(检查员) 　8 15 percent. 　9 , many people say working is less safe now.

For women workers, the greatest danger so far is murder. Forty--two percent of all 　10 who died at work were killed. Many of them work 　11 clerks in stores 12 they are alone at night. Experts say they can protect themselves by putting the cash desk in full 　13 .

The numbers of deaths and accidents at work don't take into 　14 people who become sick from　 15　 that they are exposed to at work. Doctors don't know 　16 some chemicals cause illness.

There are no government rules for many new chemicals.

Inspectors say employers 　17 their backs on safety problems because they don't want to pay the bill for fixing them. They also say some workers don't want to complain about dangers because they may ?? 18　 their jobs.

The government should force business to improve safety. There's no 　19 for workers dying or 　20 in an accident that could have been prevented.
