题目解析:
A中的surveying定位至第三句,正确,不选:When he grew older, William Smith taught himself surveying from books he bought with his small savings, and at the age of eighteen he was apprenticed to a surveyor of the local parish. 说了是从书上和实习来学习surveying,A正确,不选;同时第三句还说他的书是自己攒钱买的,不是问他叔叔借的,所以C错,选;B中的family定位至第一句,little wealth就是没钱,所以正确,不选:In 1769 in a little town in Oxfordshire, England, a child with the very ordinary name of William Smith was born into the poor family of a village blacksmith.D中的English canal定位至最后一句,正确,不选:He then proceeded to teach himself geology, and when he was twenty-four, he went to work for the company that was excavating the Somerset Coal Canal in the south of England.
