語言點
（下翻閱讀英文解釋）
A「cold front」 （冷空氣前鋒）意為一股寒流。可以用複數：There were multiple cold fronts this January.（今年一月份出現多次寒流。）
這裡的「supposed to」 （理應）指的是計劃好的或被期待發生的事。如：I thought it was supposed to rain today.（我還以為今天會下雨呢。） 在很多情況下都可以使用這一短語，例如：I thought the train was supposed to arrive at 9 a.m. sharp.（我以為火車會在九點整到達 。）
Yeah / Yup / Uh huh 都是英語為母語的人在非正式口語中常用的反應方式。這幾種方式在這裡都可以理解為「yes.」（對/是的。）加布裡拉對珍妮弗所說的話表示肯定。表示肯定的最禮貌的方式是用「yes」。
請注意聽「That’s what I read online this morning.」 （那就是今天早上我在網上讀到的。）中的重讀詞。這是個很有用的句型，它可以用其它動詞替換來表達各種意思。如：That’s what I heard on the radio. （那就是我在廣播中聽到的）/ That’s what I saw on TV.（那就是我在電視上看到的。） / That’s what I read online.（那就是我在網上讀到的。）
Chill / freezing / cold: 這些詞用來形容寒冷。如：I feel the wind chill. （我感到寒風凜冽。）/ I feel the chill. （我感到寒意。）/ I am freezing.（我凍得要命。） / I am cold.（我感覺冷。）
Wind chill （風寒效應，風寒指數）是指冷風讓人的皮膚感到比實際氣溫更低。這是一個不可數名詞。如：The temperature is 4 degrees, but with the wind chill it feels like -8.（氣溫是4度，但風寒效應使人感到像是零下8度）。這些表達方式在天氣預報中也被使用。
「driving down」 意為「壓低/壓下」，可以用在許多場合。如：An oversupply of new houses is driving down sales prices in the area.（該地區新蓋房屋供大於求，正在使房價下跌。）
