| When I reached London, it had one of
the thickest fogs in years. I could hardly see my hand in front of my face; cars
and houses ran very slowly with their lights on. When evening fell (落下；下降), it
got worse (更坏的，更差的).All traffic (交通) came (来，出现) to stop. Because I had an
important meeting on the other side of Lon-don, I had to walk. Minutes later (后来，过一会儿), I was lost. Then I heard a young woman’ s voice (声音，发言权) out of the fog. "I think you are lost. Can I help you " I could hardly see her, but I was very glad to find another person out in the fog. I told her where I wanted to go and she said she knew very well how to get there. When I walked after her through the streets, I said "How can you find the way so easily (容易地) " "I know this part of London very well," she answered. "But in so thick (厚的，浓的) a fog it’s hard to see anything," I said. [单项选择]揭示了医学科研道德的思想性内涵（）
