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 north-central 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 drought-resistant 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.
67．The underlined part “bring a good price in local markets” in the 2nd paragraph implies that lotus seeds _______.
A. can bring the local farmers more 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
68．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
69．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
70．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 extreme weather
C. the species of the world are changing quickly
D. agriculture is developing fast in the world

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.
　　An example of the dangers of a restricted diet may be seen in the disease known as “beri-beri”, which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted（传播）by a germ（病菌）. He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain. It was thought this would be easier for weak and sick people to digest.
　　Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients’ plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.
　　Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice（糙米）somehow prevented or cured beri-beri — even that a lack of some ingredient（成分）in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.
【小题1】According to the passage, a good mixed diet ________.

For hundreds of years, Japan has been hit, from time to time, by tsunamis（海啸）, which are caused by earthquakes or underwater volcanoes. The story of the boy Yuuki is the story of such a disaster.
Yuuki lived with his family in a seaside village, below a small mountain. One day, as he played on top of the mountain, Yuuki felt a small earthquake but it was not strong enough to frighten anybody. Soon after, however, Yuuki noticed the sea darken and begin running away from the shore very fast, leaving behind wide areas of beach that had never been seen before.
Yuuki remembered reading that just before a terrible tsunami, the sea suddenly and quickly rolls backward. He ran to the beach, warning the villagers who had gathered to admire the new beach land.
But no one listened. They laughed at him and continued playing in the new sand.
Desperate, Yuuki could think of only one thing to do. He lit a tree branch, raced to the rice fields and began burning the harvested rice. Then he called out, “Fire! Fire! Everyone run to the mountain! Now!”
When everyone reached the mountain top, a villager cried out, “Yuuki is mad! I saw him set the fire.” Yuuki hung his head in shame, but said nothing as the villagers screamed at him.
Just then, someone shouted, “Look!”
In the distance a huge dark wave of water was speeding towards the shore. When it hit the shore, it destroyed everything.
On the mountain everyone stared at the village ruins in terror.
“I'm sorry I burned the fields,” said Yuuki, his voice trembling.
“Yuuki,” the village chief answered. “You saved us all.”
The villagers cheered and raised Yuuki into the air. “We were going to celebrate our rice harvest tonight,” said one, “but now we’ll celebrate that we’re all still alive!”
