[单项选择]I fell in love with England because it was quaint (古雅)—all those little houses, looking terribly old-fashioned but nice, like dolls’ houses. I loved the countryside and the pubs, and I loved London. I’ve slightly changed my mind after seventeen years because I think it’s an ugly town now.
Things have changed. For everybody, England meant gentlemen, fair play, and good manners. The fair play is going, unfortunately, and so are the gentlemanly attitudes and good manners—people shut doors heavily in your face and politeness is disappearing.
I regret that there are so few comfortable meeting places. You’re forced to live indoors. In Paris I go out much more, to restaurants and nightclubs. To meet friends here it usually has to be in a pub, and it can be difficult to go there alone as a woman. The cafes are not terribly nice.
As a woman, I feel unsafe here. I spend a bomb on taxis because I will not take public transport after 10 p.m. I used to use it, but now I’m afraid.
