The 31 job is cutting down trees. Being a policeman is safer than many jobs, including driving a truck, collecting garbage and 32 airplanes. One of the safest jobs is being a librarian. The government inspects(检查) most factories and offices. Employers have to 33 fines(罚款) if their factories or offices are unsafe. In California, employers often go to prison if one of their workers is 34 because a factory didnt 35 safety measures. But President Bush cut down the number of government inspectors(检查员) 36 15 percent. 37 , many people say working is less safe now. For women workers, the greatest danger so far is murder. Forty-two percent of all 38 who died at work were killed. Many of them work as clerks in stores 39 they are alone at night. Experts say they can protect themselves by putting the cash desk in full view.

A. injuring B. being injured C. be injuring D. be injuredPassage B Avalanche and Its Safety An avalanche (雪崩)is a sudden and rapid flow of snow， often mixed with air and water， down a mountainside. Avalanches are _46_ the biggest dangers in the mountains for both life and property. All avalanches are caused by an over-burden of material， typically snowpack， that is too massive and unstable for the slope （斜坡）_47_ supports it. Determining the critical load， the amount of over-burden which is _48_ to cause an avalanche， is a complex task _49_ the evaluation of a number of factors.Terrain slopes flatter than 25 degrees or steeper than 60 degrees typically have a low _50_ of avalanche. Snow does not _51_ significantly on steep slopes; also， snow does not _52_ easily on fiat slopes. Human-triggered avalanches have the greatest incidence when the snows angle of rest is _53_ 35 and 45 degrees; the critical angle， the angle _54_ which the human incidence of avalanches is greatest， is 38 degrees. The rule of thumb is： A slope that is flat enough to hold snow but steep enough to ski has the potential to generate an avalanche， regardless of the angle. Additionally， avalanche risk increases with _55_; that is， the more a slope is disturbed by skiers， the more likely it is that an avalanche will occur. Due to the complexity of the subject， winter travelling in the backcountry is never 100% safe. Good avalanche safety is a continuous _56_， including route selection and examination to the snowpack， weather _57_， and human factors. Several well-known good habits can also _58_ the risk. If local authorities issue avalanche risk reports， they should be considered and all warnings should be paid _59_ to. Never follow in the tracks of others without your own evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain and note obvious avalanche paths where plants are _60_ or damaged. Avoid traveling below others who might trigger an avalanche.（ ）46. A. amongB. ofC. toD. in（ ）47.
