VII.Translation from English into Chinese (15 points) 將下列短文譯成漢語。

　　Many of the plants and animals from which our food comes can produce themselves quite well without our help. Fish, for example, live and breed according to their own life pattern. Human "producers" then come with nets and fishing poles to take the fish from the water.

　　In our specialized world, however, it is not always possible to let our food grow in its own way. A relatively small number of people are responsible for producing large quantities of food. In order to perform such a function effectively, it is necessary for them to raise cattle and grow crops in a fairly concentrated area.

　　Fishing, livestock(家畜) breeding, and fruit, vegetable, and grain growing are among the more commonly known food-production industries.
