①这10个点无论如何也不在一条直线上,因此小车运动的v-t图像不可能为一条直线,而应为一条平滑的曲线
②这10个点中有8个点虽然不在一条直线上,但它们紧挨在一条直线附近,只有F和B两点离这条直线太远,图像可能为一条直线
③在10个点当中只有4个点能画在一条直线上(A、D、G、I),有6个点不在该直线上,这条直线肯定不能表示小车运动的规律
④与直线偏离较小的点(C、E、H、J)可能是实验误差造成的,而与直线偏离较大的点(B、F)则可能是实验中出现错误造成的
A.①③ | B.②④ | C.①② | D.③④ |

One day, a college student was taking a walk with a professor.As they went along, they saw lying in the path a pair of old shoes.They supposed the shoes belonged to a poor man who was employed in a field close by, and who had nearly finished his day's work.
The student turned to the professor, saying, “ Let us play the man a trick: we will hide his shoes, and hide ourselves behind those bushes, and wait to see his confusion when he cannot find them”.
“My young friend,” answered the professor, “we should never amuse ourselves at the expense of the poor.But you are rich, and may give yourself a much greater pleasure by tricking on the poor man.Put a coin into each shoe, and then we will hide ourselves and watch how the discovery affects him.”
The student did so, and they both placed themselves behind the bushes close by.The poor man soon finished his work, and came across the field to the path where he had left his coat and shoes.After he slipped his foot into one of his shoes, he felt something hard.He bent down to feel what it was, and found the coin.Astonishment and wonder were seen on his face.He fixed his eyes on the coin, turned it round, and looked at it again and again.He then looked around him on all sides, but no person was to be seen.He now put the money into his pocket, and continued to put on the other shoe; but his surprise was doubled on finding the other coin.His feelings overcame him.He fell upon his knees, looked up to heaven and cried a sincere thanksgiving, in which he spoke of his wife, sick and helpless, and his children without bread. He said the help would save them from dying.
The student stood there, deeply affected, and his eyes filled with tears.“Now,” said the professor, “are you not much better pleased than if you had played your intended trick?”
The youth replied, “You have taught me a lesson which I will never forget.”
