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

For several years, scientists have been testing a substance called interferon(干扰素), a possible wonder drug that is proving to be effective in treating a variety of diseases, including virus infections, bacterial infections, and cancers. To date, the new drug has no side effect of great influence to discourage its use.  But in spite of its success, last year only one gram was produced in the entire world.

The reason for the shortage lies in the structure of interferon. A special protein, the interferon produced from one animal species cannot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting white blood cells with a virus. Fortunately, it is so effective that the amount given to each patient each time is very small.

Unlike antibiotics (抗生素), interferon does not attack germs directly. Instead, it protects healthy cells from being infected, and prevents the reproduction of viruses within cells.

As you might conclude, one of the most special uses of interferon has been in the treatment of cancer. Dr. Hans Strander, a research physician at Sweden’s famous Karolinska Institute, has treated more than one hundred cancer patients with the new drug. Among a group of selected patients who had received operations for advanced cancer, half were given  traditional treatments and the other half were given interferon. Among those treated with interferon 70 percent of them remained alive over three years, as compared with only 10 to 30 percent among those who had received the traditional treatments.

In the United States, a large-scale project supported by the American Cancer Society is now under way. If the experiment were successful, interferon could become one of the greatest medical discoveries of our time.

1.What is the difference between antibiotics and interferon?

A. Interferon has serious side effects, while antibiotics do not.

B. Antibiotics kill germs by attacking them directly, while interferon does not.

C. Antibiotics are very effective, while the effect of interferon is limited.

D. They are different in structure, although they are both proteins.

2. According to the passage, if 170 cancer patients received interferon treatment, how many of them would remain alive over three years?

A. About 30.

B. About 50.

C. About 120.

D. About 70.

3. The passage tells us that ________.

A. it is difficult to produce interferon in large quantities because of its special structure.

B. interferon is produced widely in lots of countries.

C. few of the patients who had received traditional treatments remained alive.

D. most of the patients who received interferon also needed traditional treatments.
