Read the text and answer the questions: Chicago, where I am from is called “the Windy City”. In the winter a cold wind blows off Lake Michigan and it snows a lot. The temperature gets very cold, sometimes below zero. In the spring, the weather is great. It’s warm and snow melts. People plant gardens and start to play outdoor sports like baseball. In the summer, it’s hot and sometimes humid. People swim and turn on their air- conditioners to keep cool. Sometimes it rains or we get thunderstorm. In the fall it’s cool. People prepare for winter and buy warm clothes like coats and hats. The leaves change colors and fall from the trees. It’s very beautiful. 1.When do the leaves change colours in Chicago? 2.When do people plant gardens? 3.It is humid in winter? 4.What's the weather like in spring?
