阅读短文，回答下列问题。

     A farm is always a busy place. One of the busiest things is when the farmer is getting land ready to

grow plants.

     If the farmer is going to grow wheat, he has to turn the ground over first. The farmer drives up and

down the paddock on a tractor. When the ground is ready, the farmer sows the seeds. He does this

with a machine that the tractor pulls along. Now, one farm and one machine can do as much a day as

twenty men used to do without a machine. After the wheat has been sown, the farmer keeps a lookout

for rain. Wheat needs rain and warm sunny days to make them grow. When the wheat has grown, it

turns a lovely golden colour.

     When the wheat is fully grown, you can see the seeds on the wheat plants. These have to be cut off

and put in bags or big trucks to be taken to a factory where they are made into flour.

     It's a very busy time on the farm when the wheat is being cut. Everyone helps so that all the wheat can

be taken from the paddocks before the rain comes. If heavy rain falls, the farm must wait for the ground

to dry out before the machine can cut the wheat. Farmers always have a lot to do through the year.
