Section A （10 points）
Directions: Read the following passage. Complete the diagram / Fill in the numbered blanks by using the information for the passage.
 Write NO MORE THAN 3 WORDS for each answer
The United Nations estimates that world food production will have to increase by 70% by 2050. A world population growing in number and wealth will require one billion tons more grain each year, and two hundred million tons more meat.
The Food and Agriculture Organization says those gains will have to happen largely on existing land. However, according to a new report which provides the first "global assessment of the state of the planet's land resources”, large parts of all continents are experiencing damage. One-fourth of all land is described as "highly degraded(退化) ".  The greatest threats are losses of soil quality, biodiversity and water resources. Therefore, production rates have been slowing in many areas. Though new agricultural methods and technology are used to increase food production in many countries, yet they have also harmed the land and water. Thus, it calls for greater use of ways that can expand production while avoiding damage to ecosystems.
One such practice might be the use of "fertilizer trees." These are fast-growing trees and shrubs（矮树丛） whose leaves and roots help make soil richer. 
Oluyede Ajayi, the leader author of the study, said "Basically these are trees that can fix nitrogen(氮) from the atmosphere and change them into nitrates（硝酸盐） for fertilizer, for organic fertilizer, for the soil."
The farmers who planted fertilizer trees reported double the corn production of other farmers. In Zambia, the fertilized fields provided up to 114 additional days of food. Farmers say they need less rainwater if they use fertilizer trees. The trees reduce water runoff and soil erosion.
 A recent study found that about 400,000 farmers in southern Africa are using them. The farmers themselves designed and managed part of the testing in the field, and spread the word of their successes.

Fertilizer trees can be used to increase food production
Problems	● World population growth   71     the increase of world food production ● Large parts of global land    72    by losses of soil quality and water resources, slowing production rates ● New agricultural technology is    73    to land and water
74	Growing fertilizer trees to expand food production without    75    .
76 of fertilizer trees	● Having leaves and roots    77    soil ●    78    into nitrates for the soil ●    79    and loss of soil
Good result	Farmers using fertilizer trees can produce    80    as much corn as other farmers.
