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(收成)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(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer(层) 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(数量)of water must be used. Too much water can form a thicker layer of ice that will break the tree’s branches(树枝). 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(设备), air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate(计算) 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(利益) of computer—age oranges.
The passage is mainly about______.

A.a farmer expert cares for his orange trees
B.the different uses of computers
C.growing oranges in Florida’s changeable weather
D.different ways of frost protection

Ed tries to protect his crop by______.

A.using a wind machine to drive away the cold air

A.removes the need for frost protection
B.prevents temperature from dropping
C.tells farmers why outdoor temperatures change
D.helps the farmer get a better harvest

Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing(缝纫)or reading.
After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn’t wash her window. It really looks terrible.”
One bright morning I decided to clean my flat, including washing the window inside. Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible(可见的). Her window was clean!
Then it dawned on me. I had been criticizing(批评)her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings(缺点)? Since then, whenever I wanted to judge(评判)someone, I asked myself first, “Am I looking at him through my own dirty window?” Then I try to clean the window of my own world so that I may see the world about me more clearly.
The writer was surprised that______.

A.the woman was sitting by her window
B.the woman’s window was clean
C.the woman did cleaning in the afternoon
D.the woman’s window was still terrible

A.one shouldn’t criticize others very often

Dear Victor,
I am a college student. Nowadays games on the net are very popular with college students. Some of my roommates are very interested in them. They not only play games in their free time, but also keep talking about them at night when lights are off, and they regard games as a part of their life. I’ve asked them to give it up, but they wouldn’t listen to me. It has become a rather big problem. Should I report it to our teachers or do something else?
Ted
Dear Ted,
Drop it. Your roommates, as grown—ups, can do whatever they want with their time so long as it doesn’t break school rules or violate(妨碍)other people’s interests.
Playing perhaps gives these students relaxation from hard study. If they play too often and have little time to study, they will reap what they have sown(自食其果), but you will not. Reporting to the teachers would only harm your good name in your dormitory(宿舍). However, you have rights to ask your roommates to be quiet when you need sleep. If they aren’t angry with you, they will stop talking. But be polite and friendly. Perhaps, in return, join them in a game or two.
Victor
