Question

  Farmers may not be able to prevent natural disasters,but they can at least try their best to reduce losses.

  For example,they can plant crops that are more likely to survive extreme weather. In northcentral Vietnam,people with small farms do not plant rice between September and December. Seasonal rains might destroy the rice. So instead,they plant lotus seeds on raised beds. The United Nations Food and Agriculture Organization says the lotus seeds bring a good price in local markets.

  Farmers in the Philippines are showing new interest in crops like winged beans,string beans,arrowroot and cassava. The Asian Disaster Preparedness Center says traditional crops like these can survive the fierce storms that often strike the islands.

  The United Nations says some African farmers grow bambara groundnuts during long dry periods. The seeds of this droughtresistant plant can be boiled for eating or for making flour.

  In some parts of the world,farmers grow vetiver grass. Researchers in Thailand wrote about vetiver in 2007 in the journal Science Asia. They noted that the grass can absorb and control the spread of harmful waste waters,like those from pig farms.

  Agricultural expert and author William Rivera says vetiver resists difficult conditions. It reduces damage from heavy rains. And vetiver planted on earthen dams may strengthen them against breaks and flooding.

  William Rivera also speaks approvingly of alfalfa. Its deep roots can find and take up groundwater. Those roots also help hold the soil against winds. And alfalfa can be a valuable food source for animals.

The deep and extensive roots of sunflowers make them another good candidate for resisting extreme conditions. The tall plants have brightly colored heads that provide seeds and oil.

  North Dakota grows more hectares of sunflowers than any other American state. But North Dakota is better known as a top wheat producing state.

Hans Kandel works at the North Dakota State University Extension Service in Fargo. He says farmers in some parts of North Dakota plant wheat that is ready to harvest in only about one hundred days. That way it can grow before the hot,dry months of July through September.

(   ) 1. The underlined part "bring a good price in local markets" in the 2nd paragraph implies that lotus seeds         .

   A. can bring the local farmers some profit

   B. will satisfy the needs of the local people

   C. are what the local farmers eat every day

   D. don't sell very well because of their high prices

(   ) 2. Vetiver grass is planted because it can         .

   A. be a valuable food source for animals

   B. survive the fierce storms in summer

   C. provide seeds and oil

   D. be useful in many aspects

(   ) 3. From the last paragraph we can see that the farmers in North Dakota         .

   A. are not hardworking so they are suffering from poverty

   B. are good at taking advantage of the weather conditions

   C. don't have enough knowledge of weather and farming

   D. plant more sunflowers than wheat

(   ) 4. From this passage we may safely conclude that         .

   A. weather conditions are always decisive factors in agriculture

   B. some crops can help farmers to fight against disasters

   C. the species of the world are changing quickly

   D. agriculture is developing fast in the world
