The experts on famine noted that several nations still have severe shortages of food.  However,  they said,  there is progress.  For example,  China and India have reduced hunger sharply in recent years,  and studies have shown which methods work best at reducing hunger in other parts of the world.  The experts urged public officials and aid groups to take four steps to reduce hunger.

 The first step is to end famine.  They said neutral international organizations should protect civilian food supplies in areas at war.  They also said nations should improve their methods of sending food to emergency locations.

 The second step is to produce more food for the world's poorest families.

 The best way is with more modern farming methods.  The green revolution made it possible for India and other nations to greatly increase harvests,  yet these farming methods are far from perfect.  They do not work everywhere,  and they can cause environmental damage.  That is why nations must balance their agricultural needs and environmental resources.

 The third step is to protect mothers and young children against food shortages. The experts said mothers and young children suffer the most from hunger.  Many lives can be saved by making sure they are the first to get assistance. 

Finally,  the experts urged efforts to overcome two serious medical problems linked to food shortages.  The first is lack of iodine.  The other problem is even more widespread.  It is a lack of vitamin A.  Both iodine and vitamin A can be supplied to people at very low cost.


 1.  In the first paragraph,  China and India are mentioned as examples to show      ________.

 A.  the severe problem of food shortage the world is facing

 D.  their great efforts for the people


2.   According to the experts,  when two countries are at war, ________.

 A.  neutral international organizations should offer enough arms

 B.  the farmers should make a green revolution

 C.  the governments should guarantee enough food supplies to emergency areas

 D.  mothers and young children should be protected first.


3.   What's the author's attitude toward the farming methods in the green revolution? ________.

 A.  Pleased  B.  Supportive  C.  Indifferent D.  Angry


4.   Which of the following statement is correct,  according to the passage?________

 B.  Modern farming methods did little to produce more food.

 C.  Green revolution was the best way to reduce hunger.
