    The Paris Agreement(巴黎协定) sets up a goal of cutting down the earth temperature to less than 2℃. If the warming gets above 2℃， there will be serious problems on the earth like natural disasters.

    It was a beautiful spring（春天） morning. There wasn't a cloud in the sky, and the sun was warm but not too hot. So Mr. Andrews was surprised when he saw an old man at the bus-stop with a big umbrella in his hand.

    Mr. Andrews said to him, “Do you think it's going to rain today?”

    “No,” said the old man, “I don't think so.”

    “Then are you carrying the umbrella because the sun is too hot?”

    “No, the sun is not very hot in spring.”

    Mr. Andrews looked at the big umbrella again, and the man said, “I am an old man, and my legs are not very good, so I really need a walking-stick (拐杖). But people will say, 'Look at that poor old man', and I don't like that. When I carry an umbrella in fine weather, people only say, 'Look at that stupid（愚蠢的）man'.”
