单选题1 Even today, when air and road travel has made Africa so readily accessible to Europeans and Americans, there are innumerable aspects of African life which tend to take one by surprise. The unfamiliar lies hidden everywhere, and the presence of Western culture seems merely to emphasize this unfamiliarity. Basically, the essence of our reaction to the strange, the unfamiliar, is a sense of fear. Every country contains landscapes that arouse unease—whether it be some remote Alpine valley, the wild lavender fields of Upper Province, or a lonely Norwegian fjord at twilight. But in my own experience West Africa contains more weird and eerie regions—rainforest, mangrove swamp, parched plains of red earth—than any other place that I have seen. It is not only in the foreigner that these land- scapes evoke fear. A large part of all old African religions is devoted to soothing the un- known and the unseen—evil spirits which live in a particular tree or a particular rock, a thousand varieties of ghosts and witches, the ever-present spirits of dead ancestors or rela- tives. I have myself been kept awake at night in Calabar by a friend from Lagos who was convinced that the witches of the east were out to get him, or that he was about to be kid- napped and eaten. During four and a half hours in a canoe along the creeks of the Niger delta, gliding over the still and colorless water beneath an equally still and colorless but burn- ing sky, I, too, have experienced a sense of fear, or at least a sense of awe. Except for the ticking of the little outboard engine the silence was complete. On either hand stretched the silver-white swamps of mangrove, seeming, with their awkward exposed roots, to be standing knee-deep in the water. Where the creek narrowed you could peer deep into these thickets of mangroves--vistas secret, interminable and somehow meaningless. There was no sign of life except for the shrill screech of some unseen bird. I was on my way to the ancient slaving port of Bonny, which we reached in late afternoon. Scrambling up some derelict stone steps (slithery with slime and which had managed to detach themselves from the landing-stage so that you had to jump a two-foot gap to reach wet land), I found myself in an area of black mud and tumbled blocks of stone.

One way to keep from hearing sound is to use ear plugs. Another way is to cancel out the sound with anti-sound. Using a noise maker controlled by a microprocessor, engineers have produced sound waves that are half a wavelength out of phase with those of the noise to be quieted--each peak is matched to a trough, and vice versa. Once the researchers have recorded the offending sound, a microprocessor calculates the amplitude and wavelength of sound that will cancel out the highest and lowest points of the noise. It then produces an electric current that is amplified and fed to a loudspeaker, which produces anti-sound and wipes out the noise. If the anti-sound goes out of synchronization, a microphone picks up the leftover sound and sends it back to the microprocessor, which changes the phase of the anti-sound just enough to cause complete silence. The research team has concentrated on eliminating low-frequency noise from ship engines, which causes fatigue that can impair the efficiency and alertness of the crew, and may mask the warning sounds of alarm and fog signals.

单选题Ask an American schoolchild what he or she is learning in school these days and you might even get a reply, provided you ask it in Spanish, but don't bother, here's the answer: Americans nowadays are not learning any of the things that we learned in our day, like reading and writing. Apparently these are considered fusty old subjects, invented by white males to oppress women and minorities. What are they learning? In a Vermont college town I found the answer sitting in a toy store book rack, next to typical kids' books like "Heather Has Two Mommies and Daddy is 'Disfunctional'". It's a teacher's guide called "Happy To Be Me", subtitled "Building Self-Esteem". Self-esteem, as it turns out, is a big subject in American classrooms. Many American schools see building it as important as teaching reading and writing. They call it "whole language" teaching, borrowing terminology from the granola people to compete in the education marketplace. No one ever spent a moment building my self-esteem when I was in school. In fact, from the day I first stepped inside a classroom my self-esteem was one big demolition site. All that mattered was "the subject", be it geography, history, or mathematics. I was praised when I remembered that "near", "fit", "friendly", "pleasing", "like" and their opposites took the dative case in Latin. I was reviled when I forgot what a cosine was good for. Generally, I lived my school years beneath a torrent of castigation so consistent I eventually ceased to hear it as people who live near the sea eventually stop hearing the waves. Schools have changed. Reviling is out, for one thing. More important, subjects have changed. Whereas I learned English, modern kids learn something called "language skills". Whereas I learned writing, modern kids learn something called "communication". Communication, the book tells us, is seven per cent words, twenty three per cent facial expression, twenty per cent tone of voice, and fifty per cent body language. So this column, with its carefully chosen words, would earn at most a grade of seven per cent. That is, if the school even gave out something as oppressive and demanding as grades. The result is that, in place of English classes, American children are getting a course in "How to Win Friends and Influence People". Consider the new attitude toward journal writing. I remember one high school English class when we were required to keep a journal. The idea was to emulate those great writers who confided in diaries, searching their soul and honing their critical thinking on paper. "Happy To Be Me" states that journals are a great way for students to get in touch with their feelings. Tell students they can write one sentence or a whole page. Reassure them that no one, not even you, will read what they write. After the unit, hopefully all students will be feeling good about themselves and will want to share some of their entries with the class. There was a time when no self-respecting book for English teachers would use "great" or "hopefully" that way. Moreover, back then the purpose of English courses (an antique term for "Unit") was not to help students "feel good about themselves", which is good because all that reviling didn't make me feel particularly good about anything.
