单选题Which of the following factors will not affect the time of the tide?

单选题We used to think that the left brain controlled your thinking and that the right brain controlled your heart. But neuroscientists have learned that it's a lot more complicated. In 2007, an influential paper in the journal Behavioral and Brain Functions found that while most of us process emotions through the right hemisphere of the brain, about 35 % of people—especially victims of trauma—process their hurt and anger through their left brain, where logic and language sit. That may be because they had worked so hard to explain, logically, why they were suffering. But pushing emotions through the left brain taxed it: these people performed significantly worse on memory tests. Now a new paper—out in the September issue of The Journal of Nervous and Mental Disease—further complicates the picture with a surprising finding: whether you are right-handed, left-handed or ambidextrous (which the authors call, rather delightfully, " inconsistently handed") seems to be an important clue in understanding how you use your brain to process emotions. It's been known for some time that lefties and the ambidextrous are more prone to negative emotions. The new study shows that they also have a greater imbalance in activity between the left and right brains when they process emotions. Of course, you can't be sure which comes first: maybe angry people are more out of balance, or maybe the inability to find equilibrium makes you angry. As for the left-handed: maybe they're more angry because the world is designed for the right-handed majority. The study also used an interesting method to find that angry people are, literally, hot-headed: the authors of the paper—led by Ruth Propper, a psychology professor at Merrimack College in Massachusetts- measured brain-hemisphere activation with a relatively old method called tympanic membrane temperature, which is essentially how hot it is in your inner ear. If you get angry a lot, your head tends to be warmer. One problem is that the study was small —just 55 undergraduates participated (they were paid $20 each for having to endure ear-temperature tests and psychological questioning). Also, The Journal of Nervous and Mental Disease, while peer-reviewed, is one of less-respected psychology journals. Still, I like the study just because it explains that when you get hot under the collar, you are actually hot under the collar.

单选题Do people everywhere agree on what a mountain is? The fact is that definitions vary. Everyone admits, for example, that Everest is, a mountain, the highest of them all, with an altitude of almost 30000 feet. But what about Snowdon, the loftiest peak in Wales? It rises a mere 3000 feet, yet it is also called a mountain. Comparison, a little matter of relativity, is the key. To the average person living on North America"s Great Plains, Vermont"s Green Mountains look lofty indeed, but to anyone from the Rocky Mountains, the Great Mountains seem nothing more than hills. Geographers generally agree that, to be a mountain topographically (在地形学方面), a landmass must reach, an altitude of 3000 feet above the level of the sea. Mount Everest, for instance, is 30000 feet above sea level, but only 15000 feet above the neighboring Tibetan plateau. Geologists restrict the definition even more, maintaining that a mountain is a mountain by virtue of its geological structure. Some rugged highlands are not really mountains, while some flat, low-lying rock surfaces are true mountains. They are low now because of centuries of erosion. There are even mountains under the sea, the Mid-Atlantic Ridge, for example. Like all true mountains, they were originally formed by large-scale movements of the earth"s crust.

单选题(2002)She didn't break the bad news to her mother_____that she might break down.

单选题A hundred years ago, the game we now call football did not exist. American football started during a game between two colleges. The teams had got together to play what they called "football", but each team played by different roles. One team played what we now call soccer. The other played what we now call rugby (橄榄球) . Both games had been invented a thousand years before. In the first kind of football game ever played, all the men from one village tried to kick a ball into another village. The men of the second village tried to kick the ball into the first. Hundreds of people joined in, running everywhere, running crops and knocking down fences. In time, people agreed on some rules to keep order, but many rules were left open to change. Different rules developed in different places. When the two colleges met to play football, each followed its own rules. They mixed the games together and invented a new game. A hundred years later we call that game American football. In what ways do you suppose the game we know now will have changed in another hundred years?
