From this passage, I realized that Madame Curie had the spirit of tracing the source and perseverance. Madame Curie was not the first person to discover radioactivity, but she was the most crucial one. It is because she has the spirit of asking questions that she asked, "Are other substances radioactive?" This doubt. Two years later, she discovered two radioactive elements, polonium and radium, which had a lot to do with her personality. Also, if Madame Curie thought the experimental conditions were too difficult and gave up, she would not have achieved such results.
From the story of Madame Curie, I thought of myself. In August this year, I participated in the investigation of artificial bird's nest in Badaling Forest Park. As birds are very active in the early morning, we set off at 5: 30 in the morning and arrived at our destination one hour later. We walked along the railway line and had to cross a very dangerous path. Observation requires us to keep our eyes on the bird's nest (staring at it), capture the bird's in-and-out activities, make records, and walk forward at the same time ... After walking on the mountain road for several hours, I can hardly walk. I am really tired! My legs are sore and my neck is straight. I started to back down and didn't want to do it, but I stuck to it. I am ashamed to read Madame Curie's article. Madame Curie's scientific examination conditions are much more difficult than ours! It is hot in summer and cold in winter. I don't rest all year round. I have to take notes, be careful and risk my life ... they have overcome so many difficulties one after another. What is this difficulty I encountered?
Doing anything is by no means easy, nor can it be done once and for all. But persistence is victory. It is because of persistence that things can succeed. Maybe sometimes it's only a small step to success. Perseverance will climb the highest mountain. Isn't this Madame Curie's success?
