单选题{{B}}Passage Three{{/B}} There are so many bad things about women drivers, I don't know where to start. I guess I will get the bail rolling by talking about one of my biggest pet peeves. Why do women have to wait until they are in the car and barreling down the highway at sixty miles an hour before they decide it is time to put on their makeup? Is there a law that I don't know about that says women have to do their makeup in the car because the bathroom isn't good enough for them? I don't know if anyone has ever informed women, but the mirror in the car is not a makeup mirror. The mirror is used for looking at other cars and pedestrians. So please do us all a favor and do your makeup before you leave the house. The next order of business for the men should be to find out whose brilliant idea it was for women to have a phone in the car. This has disaster written all over it. Everyone knows that women can't even walk and chew gum at the same time, so how in the hell are they going to drive and talk on the phone? Why is it that every time you are sitting at a red light the woman in front of you thinks this is a good time to make a phone call? "HELLO LADY. THE LIGHT IS GREEN, GET OFF THE PHONE AND GO!" I really think we need to outlaw women using their cell phones while they drive. Another accident waiting to happen is when you get two women in the same car together. How many times have you seen two women just yakking away and the driver isn't paying attention to where she is going? There is either one of two things that happens when two women get in the car together. One. The women are talking and the driver doesn't see the stop sign in front of her, so she runs it. Two: The two women are talking and at the last minute the driver realizes there is her turn, so she stops really quick in front of you and you almost rear-end her. So women please pay more attention to your driving and, for the love of God, use your turn signals--they aren't there for decoration. I know all women out there are yelling at me and saying, "Women are better drivers than guys." If women were better drivers than men, why do guys drive on dates? Why don't women ever tell the guy, I will come pick you up? Why are almost all truck drivers guys? Why is it when a woman is going to move and she rents a U-Haul van, she always Calls a guy to drive it for her? When was the last time you watched a woman win the Indy 500 or Daytona 500? All of these questions .just go to prove why guys are the kings of the road.

单选题It vanished in 2002, a result of a bad fall. As my neurosurgeon explained, when my head hit the ground, my brain sloshed around, which smashed delicate nerve endings in my olfactory system. Maybe they'll repair themselves, she said (in what struck me as much too casual a tone ), and maybe they won't, If I had to lose something, it might as well have been smell; at least nothing about my personality or my memory had changed, as can happen with head trauma. So it seemed almost churlish to feel, as the months went on, so devastated by this particular loss. But I was heartbroken. My sense of smell was always something I took pleasure in. Without scent, I felt as ff I were walking around the city without my contact lenses, dealing with people while wearing earplugs, moving through something sticky and thick. The sharpness of things, their specificity, diminished. I couldn't even tell when the milk had gone bad. Oddly, my sense of taste remained perfectly fine, but I was still nervous about opening a carton of yogurt without having someone nearby to sniff it for me. I had been stripped of the sense we all use, often without realizing it, to negotiate the world, to know which things are safe and which are dangerous. After nearly a year, I talked to a colleague savvying about neuro-science, who suggested I try to retrain my sense of smell on the assumption that the nerve endings had repaired themselves but that something was still broken along the pathway from nose to brain, where odor molecules activate olfactory receptors (the subject of this year's Nobel-winning research) . Her advice was to expose myself to strong, distinctive fragrances, asking the person I was with to tell me exactly what I was smelling even if I wasn't conscious of smelling anything at all. I began sticking my nose into everything that seemed likely to have a scent-the cumin in the spice cabinet, freshly ground coffee, red wine. I interrupted friends midsentence if we happened to be walking past a pizza place or a garbage truck and asked, stupidly, "What are you smelling now?" Slowly, the smell therapy started to work. At first, distressingly, all I could smell were unnatural scents: dandruff shampoo, furniture polish, a cloud of after-shave from a stocky young man. The first time I smelled cut grass again, in the small park near the American Museum of Natural History, was almost exactly two years after my fall. It made me cry. The tears embarrassed me, but cut grass is one of those fragrances that transport me directly to the landscape of childhood. And that's what I had been missing, really, and why getting back my sense of smell was so precious: a visceral connection to the person I used to be.

单选题Culture shock is the result of the removal of the familiar. Suddenly the individual is faced with the necessity of working, commuting, studying, eating, shopping, relaxing, even sleeping, in an unfamiliar environment organized according to unknown rules. In mild form, culture shock shows itself in symptoms(症状)of fatigue, irritability(易怒)and impatience. Being unable to interpret the situations in which they find themselves, people often believe they are being deliberately deceived or exploited by host-country nationals. They tend to perceive(感觉，觉察到)rudeness where none is intended. Their efficiency and flexibility is often impaired and both work and family suffer. Some people may respond by developing negative stereotypes(老一套)of the host culture, by refusing to learn the language and by mixing exclusively(排外地，专有地)with people of their own cultural background. In extreme cases, rejection may be so complete that the individual returns immediately to their own culture, regardless of the cost in social, economic or personal terms. Alternatively, people may retreat into their own private world, either mentally or physically.
