Answer 1

答案：1．A;2．B;3．B;4．C;5．C;6．B;7．C;8．A;9．B;10．C;11．B;12．D;13．D;14．C;15．A;16．B;17．B;18．B;19．A;20．B;
解析：

(1)	begin…as＝work…as根據(jù)上下文的意思，可以知道愛因斯坦開始是做數(shù)學(xué)老師的。故選擇A項(xiàng)。
(2)	the following year＝the next year“下一年，隨后的一年”。below側(cè)重指位置，通常作后置定語，C、D選項(xiàng)意思講不通。
(3)	held與前面的a position構(gòu)成固定短語，意思是“擔(dān)任……職務(wù)(位)”。
(4)	根據(jù)上下文意思，應(yīng)該是愛因斯坦在工作之余“寫”了三篇非凡的論文，故應(yīng)該選擇C項(xiàng)。
(5)	on在這兒意思是“關(guān)于……”正式用語，在口語中用about“關(guān)于……的論文”。
(6)	for后面是一個(gè)介詞賓語從句，缺少主語，所以選用what。故選擇B項(xiàng)。
(7)	evidence for/of sth．“……的證據(jù)”，故選擇C項(xiàng)。
(8)	make contributions to…“對(duì)……作出貢獻(xiàn)”，為固定搭配，故應(yīng)該選擇A項(xiàng)。
(9)	extend…to…“把……延伸(擴(kuò)大)到，適用于……”，故應(yīng)該選擇B項(xiàng)。
(10)	根據(jù)后面的by可以知道空上應(yīng)該選用過去分詞形式，意思是：由機(jī)械力引起的加速度。故應(yīng)該選擇C項(xiàng) 提示：
