Read the article and select the best answer. Article: My parents taught me not to waste food. My mum always found ways to make leftovers taste good. I went to YiLan to learn about some of their special food. As I was there, I learned about the food and the history of the area. I learned that they don't waste food, either, and they use leftovers! Many years ago, there was not enough food for everyone. People learned to cook and eat almost everything. They had to think of ways to make special dishes. One of these dishes is kao zha.It made with leftovers like meat, soup, oil and fat. That might not sound very good, but it does taste good. Today, kao zha is a special dish at big banquets . Another famous dish is called zao bing. It's made with fruit, meat and other things. I really liked it! But I didn't want to eat too much. It has a lot of fat in it. I smelled something burning and I saw smoke, so I found another special food of the YiLan area duck meat. The duck meat is put in a big oven to cook it. Smoke keeps the meat fresh. I don't usually eat meat, but this duck meat was delicious! It tasted sweet. YiLan is a great place with delicious food. I hope I can come back again! Question: The writer learns from her parents _ . Options: A: nottoeatleftovers B: toeatgoodfood C: nottowastefood D: tomakegoodfood

Read the article and select the best answer. Article: Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida's weather. Warm sunshine and gentle rains, along with Ed Rawlings' expert care, will produce a good crop of oranges this year. However, Ed has to guard against Florida's changeable winter weather. In January and February, temperatures can destroy Ed's entire orange crop. Having farmed in Florida for the past 35 years, Ed is prepared for the frost . When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer of ice around the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm. What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is taken in by the fruit and keeps its temperature at a safe level. Ed has effectively used this method to save many orange crops. But Ed still faces difficulties. The trees must be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thicker layer of ice that will break the tree's branches . Another difficulty is that wind blows away the heat, so Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used. Computer technology may help Ed with some of these worries. With equipment , air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate when the temperature will drop below freezing. The computer can correctly decide the quantity of water to be used and how frequently( ) the trees should be watered. Ed finds looking after his orange trees a lot easier with the help of a computer, and, his customers will have the benefits of computer--age oranges. Question: Ed tries to protect his crop by _ . Options: A: using a wind machine to drive away the cold air B: equipping his orange trees with a computer C: watering it at the proper time D: picking his fruit at the first sign of frost

But even if you have a short-term memory, it's better than a chimpanzee's , right? Well, you may be wrong. Tetsuro Matszawa, a scientist from Kyoto University, Japan has showed how chimps have far better memories than humans. "We learn that chimps have great memories by doing tests," he told The Guardian "You can do things to improve your memory." How do chimps have better memories than us? Scientists tested four chimps and human volunteers. They showed them five numbers on a computer screen. Chimps and human volunteers had to remember the numbers correctly. But to make it hard, the numbers disappeared after seven tenths of a second. Then they will reduce the time to two tenths of a second. While humans began to make mistake after mistake, the young chimps still did very well. Why do they have better memories? We share 98.8 percent of our DNA with chimps. But during evolution , we lost some of our shared abilities. As humans learned new skills, like language, we had to lose some of our memory skills to make room in our brains. "To get something, we had to lose something," said the scientist. Chimps need good memories to survive . When a chimp looks up at the big tree and pick a banana, he must remember where he saw it as he fights off competition from other animals. Question: During evolution, humans _ . Options: A: lost 98.8 percent of their DNA shared with chimps B: needed very good memories to survive C: gained skills but also lost skills D: learned to compete against chimps
