Researchers from Cornell University think that it is because spice plants have some important chemicals(化学物质).These chemicals can kill bacteria(细菌)which spoil food. “Most common spices can kill 75 to 100 percent of the bacteria in food，”explains one of the scientists.The bacteria grow more easily and spoil food more quickly at higher temperatures.For this reason，it is more difficult to keep food from spoiling in hot climates， Do you like your food spicy? Your answer probably tells something about the country you come from.If you like spicy food，it is possible that hundreds of years ago，when there were no fridges，people in your country started using spices to keep the food from spoiling.The traditional spicy dishes helped those people to live longer，healthier lives.Today，in a time of fridges，the spices just make the food taste good. 39.The chemicals in spices keep food from spoiling by_________.

When I traveled across to the other side of the island (岛屿), I could see the other islands, and I said to myself, “Perhaps I can get there with a boat. Perhaps I can get back to England one day.” So I decided to make myself a boat. I cut down a big tree, and then began 《鲁滨逊漂流记》 to make a long hole (洞) in it. It was hard work, but about six months later, I had a very fine canoe (独木舟). Next, I had to get it down to the sea. How silly I was! Why didn’t I think before I began work? Of course, the canoe was too heavy. I couldn’t move it! I pulled and pushed and tried everything, but it didn’t move. I was very unhappy for a long time after that. That happened in my fourth year on the island. In my sixth year I did make myself a smaller canoe, but I did not try to escape in it. The boat was too small for a long journey, and I did not want to die at sea. The island was my home now, not my prison, and I was just happy to be alive. A year or two later, I made myself a second canoe on the other side of the island. I also built myself a second house there, and so I had two homes. My life was still busy from morning to night. There were always things to do or to make. I learnt to make new clothes for myself from the skins of dead animals. They looked very strange, it is true, but they kept me dry in the rain. I kept food and tools (工具) at both my houses, and also wild goats (山羊). There were many goats on the island, and I made fields with high fences to keep them in. They learnt to take food from me, and soon I had goats’ milk to drink every day. I also worked hard in my corn (玉米) fields. And so many years went by. 42.
