Benjamin spent a lot of time learing about _____.
A.how did ships work B.how ships work
C.how ships worked D.how did ships worked
我知道选C

learn 是动词,learn about 是动词性短语,后+宾语从句.从句第一大特点：陈述语序!也就是主语+谓语+宾语结构.如果你分不清句子成分,记住：动词做谓语,人或者物做主语.即是人、物 +动词.陈述语序肯定句,不用助动词did.所以AD排除.前面用的spent可见是过去时,（常识也知道本杰明富兰克林都死了好多年了）,动作肯定是过去发生的.所以选择C
