完形填空

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（草地） on tractor（拖拉机）. 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（守望） for rain. Wheat needs rain and warm sunny days to make it grow. When the wheat has grown, it turns to a lovely golden colour.

When the wheat is fully grown, you can see the seeds on the wheat plants. These have to be out off and put in bags or big trucks to be taken to a factory where they are made into flour（面粉）.

It’s a very busy time on 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 dry out before the machine can cut the wheat. Farmers always have a lot to do through the year.
