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. Ed tries to protect his crop by _ . 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

She went from apartment to apartment and from house to house. She knocked on doors and asked for money. She always said the same thing. "Good morning, I'm collecting for a church charity. Please give generously. We need $5,000." Then she held out a collecting box. Most people put a few coins in the box. An artist lived in one of the apartments. He opened the door. "Good morning." she said. "I'm collecting for a church charity. Please give generously. We need $5,000." The artist thought for a moment, then he said, "I'm sorry, but I don't have any money.

Q: OUR children grew up on peanut butter and jelly sandwiches. The right jelly makes them very happy, and homemade is the only choice. I wasn't the jelly maker in this family. My mother-in-law was. She didn't provide a wide range of flavors , either. It was either grape or blackberry. And since we liked both flavors, we usually picked whatever jar was at the front of the pantry . It was always there. Jelly making was just a way of life for her. She always did it, following the same habits ---from picking the fruit to setting the finished jelly on the homemade shelves. This past December, my mother-in-law passed away. Among the things in the house to be divided up were the remaining canned goods. Each of us chose from the many jars of tomato juice, green beans and jelly. The other day I reached in there to get jelly for a quick sandwich, and there it was. Sitting all alone on the far side of the shelf was a small jar of grape jelly. Written on the lid with a black marker was "GR" for grape and the year the jelly had been made. As I picked up the jar, I suddenly realized something that I had failed to see earlier. This was the last jar we would ever have from my mother-in-law's patient, loving hands. Our children had never known a day without their grandmother's jelly. It seems like such a small thing, but it was a great treasure. Holding that last jar in my hand, my heart traveled back to meeting my mother-in-law for the first time. I saw her crying on our wedding day, and later, kissing and loving our children. I saw her walking in the woods or riding the wagon . I saw her surrounded by loving children at her funeral. I put the jelly back on the shelf. No longer was it just a jar of jelly. I guess I believed that as long as it was there, my mother-in-law would always live on. With the story, the author want to tell us that _ . A) Love from your family often hides in small things B) Homemade food is always simple but delicious C) We should always give the best things to our kids D) It's never too late to show love for our families
