两天前，天气预报预测冷风将会吹起来，今天清晨，我感到了寒冷。天气变化非常的快，下午很冷

Two days ago, the weather forecast predicted that the cold wind would blow and today, early in the morning, I felt the chillness. The weather changes so quickly that it is very cold in the afternoon. I started to feel sleepy in the class, but I tell myself to keep focus. Winter is not the excuse to loosen attention.
