• 1．Dust storms don't just happen in the middle of the desert.They happen in any dry area where loose dirt can easily be picked up.The sand blown into the air by the wind usually falls back down to the ground after a few hours.Smaller bits of particles （微粒） stay in the air for a week or longer and can be blown thousands of miles away.Dust from the Sahara is always blown across the Atlantic and keeps travelling as far as Caribbean.
     The scary thing about sandstorm is that they can spread over hundreds of miles and rise over 10，000 feet （3050 meters）.They also have wind speeds of at least 25 miles per hour （40km）.Not strong enough to blow the feathers off a chicken but still something worth avoiding.
     Don't be surprised if you suddenly see a dust storm heading your way.Dust storms usually arrive without warning and move in the form of a big wall of dust.The dust makes driving impossible.Often they only last for a few minutes but storms usually leave serious car accidents behind.If you are in a car during a dust storm，remind the driver to pull over and turn off the headlights.
     In mild （輕微的） dust storms，it's still impossible to walk around although you wouldn't want to.You can't see anything because of the dust particles flying around.It's not just the dust you want to avoid.The wind carrying the dust will leave things as if they were just hit by a tornado.The best thing to do is find a safe place in a building.

  A．Sand blown into the air can float for months.
  B．Dust storms don't happen in the heart of the desert.
  C．Dust blown into the air can travel a very long distance.

• 3．Of all nature's disasters，forest fires are often considered the most frightening.Moving at lightning speed，huge walls of flames can burn acres of land in just a few minutes.And although technology，including the use of fire-retardant chemicals，has greatly helped the fight against forest fires，they still take great damage.
     According to the National Interagency Fire Center，the fire season last year was the worst on record in terms of the number of fires and acres（公頃）burned.There were 96，385 fires and 9，873，429 acres affected by fire in a year that was 125% more destructive（毀滅性的）than the 10-year average（平均）.These fires cost the federal government ＄1.5 billion to fight，and this figure does not include the money spent by local and state governments as part of the effort.
     Fires in the southern states represented（代表）half of the national total last year with Texas，Oklahoma and Arkansas being home to an usually high amount of activity.Wildfire have also taken place in Western states such as California，Colorado and Alaska throughout the past 10 years.
     It is said that two-thirds of forest fires are started accidentally by people，almost one quarter are purposely set，while lighting causes 10%.
     Forest fires can have advantageous effects.Charcoal（木炭）enriches soil，and some plant species（種類）grow well after.The cones of the jack pine tree，for example，will not spread their seeds unless there is heat.Douglas fir trees grow best in open sunlight areas after fire.
