问题     What is it that attracts so many people to diving? The reasons are as diverse as the available experiences.

    Drift divers roll off their boats into strong tidal currents which shoot them rapidly down gullies and over reefs for a kilometer or more. Stopping is nigh impossible—like trying to stand in a hurricane. With one hand firmly gripping your partner, it is just possible to steady yourself and steer with your free hand, dodging the rocks that emerge ghost-like from the fog. This is underwater motorway madness, a crazy freedom. In these fast currents, plankton feeders emerge for an eas-y meal and divers with quick reflexes can sometimes grab an unwary scallop.
    Depth divers enjoy a different kind of trip. Ascending and descending is like night flying: unable to see either surface or bottom, you depend on your depth gauge to measure progress. If there is a line to follow to the bottom, it will gradually disappear into eerie nothingness. This is the limbo of diving: weightless and apparently motionless, you see nothing but your fellow diver. When the bottom finally rises from the gloom to meet you, the surrounding world is completely blue-green, because the deeper you go the more the colours from the red end of the colour spectrum are progressively absorbed by the water. Pressure squeezes your suit, your mask, your buoyancy regulator and your lungs, all of which have to be repeatedly inflated. You are in a dark, cold and totally alien environment.
    Then there are wreck divers. Some, armed with navigation charts and comprehensive underwater toolkits strapped to their waists, become so weighed down with mementoes it is a wonder they manage to surface at all. Most, however, are happy simply to swim along hulls that sometimes stand 15 metres or more from the sea floor, forming artificial reefs that attract a profusion of marine life. Most wrecks are just huge chunks of broken steel and many of the more intact or important ones are protected.
    Wrecks offer plenty of fascinating enclosed spaces, but only the foolhardy or the very experienced venture deep inside them. Sounds of breathing are amplified by chambers of rusting steel, and bubbles run horizontally along the plates above, seeking a way to the surface. Lobsters and conger eels peer out from their crannies, grotesquely enlarged by their proximity and the magnifying effects of water.
    For me, the ultimate thrill is night diving. All kinds of creatures, hidden during the day, e-merge at night to feed, mate and exercise. Because it is only possible to see what the torch beam picks out, colours are more defined and your attention becomes more focused. Switch off your torch and you are surrounded by the dull glow of phosphorescence(磷光), which gradually fades to total inky blackness.
Questions 56—60
Decide whether the following statements are true(T)or false(F)according to the passage.  
The writer likes night diving because the colours then are different from those during the day.
选项 A、TRUE
B、FALSE
答案B
解析 原文中讲述night diving(夜潜)的地方在最后一段。根据该段中的“All kinds of crea—tures，hidden during the day，emerge at night to feed，mate and exercise．”可知，白天藏匿起来的生物在晚上都会出来觅食、交配和活动。后面又提到，晚上只能看到手电光照射的地方，颜色清楚，注意力更集中。关掉手电后，会被周围暗淡的磷光包围。本题表述与文章意思不符，因此错误。
