W: You're right, Don. That sign says Chagford Town Hall. But there's a more interesting notice on the other side of the square. Do you see what it says？ "Open for Devon Cream Teas". M: Oh, yes, so it does. Oh, I must get a newspaper. There's a newsagent next door. W: What for？ M: To find out what's been happening. W: I don't need a newspaper. We must have been walking for at least six hours. My feet have been hurting for a- bout four hours and I've been starving since we shared that tin of cold beans. M: You're hungry again？ I see what you mean. That tea shop does look interesting. We could plan tomorrow's walk while we were having tea. W: So toady we had complete Devon cream teas, with additional sandwiches and cakes, and another order of scones. I feel better. How about you？ M: A Devon cream tea is better than a tin of cold beans. In fact, it's better than almost anything... except a good newspaper. Do you ever buy a newspaper？ W: Not often. But I watch television. M: Television! It only scratches the surface. W: Television coverage is very dramatic. M: Yes. You learn what happened but never why it happened. W: Rubbish. M: TV workers aren't in aren’t in a position to fill in the background. W: They were there. M: No, they only show you the bits. M: Yes, of course. See to it, will you, Turner. I must get a newspaper before the newsagent closes. W: Could you get me a paper？ M: What for？ W: To find out what's on television. (20) A．A tea shop. B．A newsagent. C．Lights. D．A shoes store.

Until a few years ago, the most doctors could do was to counsel patients with bad breath about oral cleanliness. Now they are finding new ways to treat the usually curable condition. Bad breath can happen whenever the normal flow of saliva (唾液) slows. Our mouths are full of bacteria feeding on protein in bits of food and shed tissue. The bacteria emit evil smelling gases, the worst of which is hydrogen sulfide (硫 化物). Mouth bacteria thrive in airless conditions. Oxygen rich saliva keeps their numbers down. When we sleep, for example, the saliva stream slows, and sulfur producing bacteria gain the upper hand, producing classic “morning breath”. Alcohol hunger, too much talking, breathing through the mouth during exercise anything that dries the mouth produces bad breath. So can stress, though it’s not understood why. Some people’s breath turns sour every time they go on a job interview. Saliva flow gradually slows with age, which explains why the elderly have more bad breath trouble than younger people do. Babies, however, who make plenty of saliva and whose mouths contain relatively few bacteria have characteristically sweet breath. For most of us, the simple, dry mouth variety of bad breath is easily cured. Eating or drinking starts saliva and sweeps away many of the bacteria. Breakfast often stops morning breath. Those with chronic dry mouth find that it helps to keep gum, hard candy, or a bottle of water or juice around. Brushing the teeth wipes out dry mouth bad breath because it clears away many of the offending bacteria. Surprisingly, one thing that rarely works is mouthwash. The liquid can mask bad breath odor with its own smell, but the effect lasts no more than an hour. Some mouthwashes claim to kill the bacteria responsible for bad breath. The trouble is, they don’t necessarily reach all offending germs. Most bacteria are well protected from mouthwash under thick layers of mucus (粘液). If the mouthwash contains alcohol-as most do-it can intensify the problem by drying out the mouth. 第31题：The phrase “emanate from” in Paragraph 1 most probably means “________”.

However, biological understanding is not enough:【B2】itself, it can never tell us what human beings are.【B3】to our physical equipment—the naked human body—we are not an【B4】animal. We are tropical creatures,【B5】hairless and sensitive to cold. We are not fast and have neither claws nor sharp teeth to defend ourselves. We need a lot of food but have almost no physical equipment to help us get it. In the purely physical【B6】, our species seems a poor【B7】for survival. But we have survived—survived and multiplied and【B8】the earth. Some day we will have a【B9】living on the moon, a place with neither air nor water and with temperatures that turn gases into solids. How can we have done all these things？ Part of the answer is physical.【B10】its limitations, our physical equipment has some important potentials.
