B

   As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.

   When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.

    There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.

    A. there are many rich valleys and large fields

   A. the land was divided into smaller pieces

   B. people moved into the countryside

   C. industrial methods were used in farming

   D. the units of land were much larger

58. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.

   A. growing new types of crops

   B. irrigation and dry-farming means

   C. providing fertilizers 

   D. destroying pests and diseases

59. Why is the land divided into tiny units in some areas?

   A. There are too many people living there.

   B. It saves more natural resources there. 

   C. It prevents crops from serious diseases there.

   D. Farmers can grow various kinds of crops there.

60. Why do some people use dams to hold back waters from great rivers?

   A. To develop a new kind of dry-farming methods.       

   B. To prevent crops from floods.

   C. To provide water and electricity in all seasons.
