William Henry Bragg was born at Westward，Cumberland，on July 2,1862.He was educated at Market Harboroagh Grammar School and afterwards at King William’s College，Isle of Man.Elected as a minor scholar of Trinity College，Cambridge，in 1881，he studied mathematics under the wellknown teacher，Dr E．J.Routh.He studied physics in the Cavendish Laboratory during a part of 1885，and at the end of that year he was elected to the Professorship of Mathematics and Physics in the University of Adelaide，South Australia.
His research interests dealt with a great many fields and he was skilled at picking up a subject，almost casually，making an important contribution，and then dropping it again.However，the work of Bragg and his son Lawrence in 1913～1914 founded a new branch of science of the greatest importance and significance，the analysis of the crystal structure by means of Xrays.It is true that the use of Xrays as an instrument for the systematic revelation of the way in which crystals are built was entirely due to the Braggs.This was recognized by the award of the Nobel Prize jointly to father and son in 1915.
He was an honorary Doctor of some sixteen universities，and a member of the leading foreign societies.Many other medals and awards were bestowed upon him among which may be mentioned the Rumford Medal in 1916 and the Copley Medal (its premier award) in 1930.
He was the author of many books，including Studies in Radioactivity，XRays and Crystal Structure，The World of Sound，Concerning the Nature of Things，Old Trades and New Knowledge，An Introduction to Crystal Analysis，and The Universe of Light.His favorite hobby was golf.After a life of astonishing productiveness，Sir William Bragg died on March 10,1942.

(答案→)A
解析：
【小题1】 A
解析 细节理解题。根据第二段最后两句可知，Bragg和他的儿子用X光成功地发现了水晶的结构，这正是他被授予诺贝尔奖的原因。
【小题2】 C
解析 细节理解题。根据第一段中提到的他对数学的学习、第二段中他对晶体结构的研究和最后一段中他喜欢打高尔夫球可知，他对数学、物理和体育都有一定的兴趣。文中并没提及他对医药感兴趣。
【小题3】 A
解析 细节理解题。由文章第一段最后一句可知，Bragg在1885年成为了阿德莱德大学的一名教授，故A项正确。
【小题4】 A
解析 主旨大意题。通读全文可知，文章主要介绍了William Henry Bragg富有成果、多产的一生。
