I'm writing a composition. 不要吵闹。我正在写作文。Let's set off. It isn’t raining now. 咱们出发吧。现在不下雨了。这类情况常与now现在，at present现在，at the moment现在，today今天，this week这个星期，this year今年等时间状语连用。2,表示现阶段正在进行而说话时不一定在进行的动作。We are working in a factory these days. 这几天我们在一家工厂工作。They are compiling a dictionary. 他们在编一本词典。We are making model planes these days.这些天我们在做飞机模型。这类情况常与today今天，this week这个星期，this evening今天晚上，these days现在、目前等时间状语连用。1.有时通过上下文可以判断出应采用何种时态，如以look, listen开头的句子，提示我们动作正进行，这时要用现在进行时。It's four o'clock in the afternoon. The children are playing football on the sports ground. 现在是下午四点。孩子们在操场上踢足球。Hurry up! We are all waiting for you. 快点！我们大家都等着你。Look! They are reading over there under the tree. 看！他们在那边的树底下看书。Listen!
