Dear Anne，

Thanks for your email．It's great to have a pen pal from another country．My name is Jeff，and my family has a farm in Australia．We grow wheat and crops on our farm．Let me tell you what happened here last week．

Until last week，our plants had been growing well because we've had a lot of rain．Then the locusts came．They flew towards our farm in a swarm（一大群），which contained millions of locusts and covered an area of several square kilometers．The locusts came from an area far away．They had flown through the night．

Early the next morning，I went outside with Dad．We looked at the swarm in the sky．I had never seen so many animals together at a time．Dad said there was nothing we could do for the crops．I wasn't afraid，because locusts don't hurt people．

The swarm landed in our fields，and the locusts ate most of our wheat．We lost a lot of our harvest．Then the locusts flew to other farms in our area and ate some of those crops，too．

I didn't go to school that day，because the swarm of locusts made it hard for drivers to see on the roads and the school bus didn't run．Instead，I helped Mum and Dad on the farm．

The locust plague（灾祸） is over now，and the locusts have all gone．Mum and Dad said we must get the damaged fields ready for the new plants．We are going to be very busy on the farm．Email me again soon．

Your new friend，

Jeff
