阅读理解专项练习 (一) All gardeners know this is going to happen every year, and yet many are still surprised when it does. I’m talking about the arrival of freezing temperatures. There will come a time when we need to protect some of our landscape plants from freezing temperatures. And since no one reliably predicts the weather, now is a good time to get ready. Many calls I receive are from the gardeners who confuse frosts and freezes. While both are cold weather events, they are completely different. Frosts relate to the amount of water in the air. When air temperatures dro p low enough, the water in the air condenses (凝结) onto surfaces as dew(small drops of water). An example of this is a cold glass of iced tea sweating on a hot summer day. Frosts typically occur when the sky is clear and the wind is calm. Heat absorbed by the soil and plants during the day goes into the air at night. Calm wind conditions allow surface temperatures to drop below freezing while higher elevations (高度) remain warmer. If the surface temperature and dew point are below freezing, ice crystals (结晶体) form on the cool surfaces. Sometimes the air is too dry for ice crystals to form, but a frost event has still occurred. A frost can occur when the air temperature is above 32°F(0°C). A freeze occurs when a mass of cold air moves into the area. This weather event often happens under windy conditions with a cloud cover. A typical freeze case is very different from a frost. When the outside air temperature falls below 32°F for a certain number of hours, a freeze can cause plant damage. A hard freeze occurs with temperatures below 28°F for a certain number of hours. So what can a gardener do to prepare for these events? Fortunately, we have lots of resources to keep us informed on the weather. TV, radio and weather websites can help us know when one is expected, though even then we can be fooled. A couple of years ago, I followed the TV forecast that called for 36°F, and I didn’t cover my lettuce plants. When I woke up the next morning, it was 26°F outside. It’s a good thing mo
