解析：

(1)	begin…as＝work…as根据上下文的意思，可以知道爱因斯坦开始是做数学老师的。故选择A项。
(2)	the following year＝the next year“下一年，随后的一年”。below侧重指位置，通常作后置定语，C、D选项意思讲不通。
(3)	held与前面的a position构成固定短语，意思是“担任……职务(位)”。
(4)	根据上下文意思，应该是爱因斯坦在工作之余“写”了三篇非凡的论文，故应该选择C项。
(5)	on在这儿意思是“关于……”正式用语，在口语中用about“关于……的论文”。
(6)	for后面是一个介词宾语从句，缺少主语，所以选用what。故选择B项。
(7)	evidence for/of sth．“……的证据”，故选择C项。
(8)	make contributions to…“对……作出贡献”，为固定搭配，故应该选择A项。
(9)	extend…to…“把……延伸(扩大)到，适用于……”，故应该选择B项。
(10)	根据后面的by可以知道空上应该选用过去分词形式，意思是：由机械力引起的加速度。故应该选择C项 提示：
