  11. Words collection 广东职业技术学院

  12. Words collection • Weather conditions: • 1) temperature: freezing, cold, chilly, frigid, cool, mild, warm, hot. • 2) sky: sunny, clear, cloudy, overcast. • 3) humidity: dry, damp, humid, wet. • 4) rain; drizzle, shower, downpour, storm. • 5) wind: breeze, gale. • heavy rain/ light rain; strong wind/light wind. • freezing point; boiling point; absolute zero. • ppm: parts per million 广东职业技术学院

  13. Notes • In an English weather forecast, the weatherman always uses some broad and general terms rather than exact words to predict weather in the future. Besides weather conditions, the temperature, wind direction, wind speed, an English weather forecast also gives the relative humidity and the barometric pressure. BACK 广东职业技术学院

  14. Part I Getting Ready A.The following words and phrases will appear in this unit. All of them are related to weather and some are frequently used in weather forecast. Listen carefully and study the definitions. • Freezing point: 冰点 • Relative humidity: 相对湿度 • Calm: 平静的，安宁的 • Barometric pressure: 大气压 • Widely scattered: 分散的，散开的 • Shower: 阵雨，阵雪 广东职业技术学院

  15. Part I Getting Ready 7. lows: 低点，低温点 cf: highs 8. variable: 可变化的 9. thunderstorm: 雷雨 10. gale: 大风 广东职业技术学院

  16. Part I Getting Ready • B.You are going to hear five statements about temperature. Write down all the degrees in both Centigrade (C) and Fahrenheit (F). • The differences between “C” and “F” • Temperature can be measured in degrees Centigrade or degrees Fahrenheit. Usually we use “℃” to stand for Centigrade or Celsius. The abbreviation for Fahrenheit is “F”. The sign for degrees is “°”. Centigrade or Celsius is commonly used in China, while Fahrenheit is widely used in English speaking countries. 广东职业技术学院

  17. Part I Getting Ready The formula for temperature conversion are: ℃= degree(s) centigrade/celsius ℉=degree(s) Fahrenteit C=5(F-32)/9 F=9C/5+32 C -10 0 10 20 30 40 50 60 70 80 90 100 F 140 32 122 158 14 50 68 86 104 176 194 212 广东职业技术学院

  18. Part I Getting Ready • The freezing point of water is 0 ℃ or 32F. • The boiling point of water is 100 ℃ or 212 F. • The normal body temperature is 37 ℃ or 98.6 F. • The temperature on a warm spring day is 15 ℃ or 59 F. • The temperature on a hot summer’s day is 35 ℃ or 95 F. 广东职业技术学院

  19. Notes • 1. Of the five statements, the last three may sound a bit challenging. In fact, the scale at the beginning has already offered the answers to the first two. Therefore, if you can get the correct answers for the last three, you've done a good job. • 2. Since the measurements in both Centigrade and Fahrenheit are being used by people in different areas, the numbers in the first three statements are useful in daily life (0°C=32°F; 100°C=212° F; 37°C=98.6°F ). Memorize them if you can. 广东职业技术学院

  20. Notes • 3. English speakers often use Fahrenheit instead of Centigrade tomeasure temperature. Notice that zero and decimal numbers are regarded as plural, for example, zero degrees;0.5 degrees. • 4. Weather forecast is given several times a day on TV and on the radio. The man who predicts weather conditions is called the weatherman. In most English speaking countries, the weatherman usually speaks with a personal and friendly tone. He acts as if he is chatting with a friend about what the weather will be like. 广东职业技术学院
