Once a man asked a painter to painting a picture for him. He told the artist he didn't want any shadows in the picture, just sunshine, but the artist did so. When the man saw the finishing picture, he was disappointing. Without shadows, everything in the picture looks flat and unreal. The point of the story is that we need both shadows and sunshine to have a completely picture, just as we need both rain and sun to have living world. People, too, needs both sadness and happiness. We often learn important lesson during sad times. So when we feel sad, we should try to stop and think about that we might learn from the experience.
在线课程【答案】
【解析】1.ask sb. to do sth.要求某人做某事，to后面跟动词原形。故将painting改为paint。
2.want sth. 想要某物，后面直接跟名词。故将to去掉。
3."just sunshine, but the artist did so."，前后之间是顺承关系，并非转折。故将but改为and。
4.disappointing通常指物，意为令人失望的，而-ed形式通常指人，意为失望的。故将disappointing 改成disappointed。
5.文章讲述的是发生在过去的故事，所以动词要用过去式。故将looks改为looked。
6.形容词在名词前修饰名词。故将completely改成 complete。
7.living world在文中第一次出现，且是泛指，需要加不定冠词。故在living world 前加 a。
8.people作主语时表示群体概念，其后谓语动词应用复数形式。故将needs改为need。
9."We often learn important lesson during sad times. "lessons表示教训时用其复数形式。故将lesson改为lessons。
10."we should try to stop and think about that we might learn from the experience."“我们应该尽力停止悲伤，而去想想我们能从经历中学到什么。”在主句中作宾语在从句中作主语，表达"什么"的概念用what。故将that改为what。
