题目内容
17.Although some surfers have been skateboarding for more than 50years,skateboarding did not peak until the 70s.In 1962,a surfer attached roller skate wheels to a board and began selling the skateboards to other surfers.The surfers used this new device to practice"surfing"while not in the water.They improved their balance and technique and had fun while practicing.
In 1973,another California surfer designed a skateboard with plastic wheels.The new wheels were stronger and made less noise.At this time,real skateboards were designed and tricks and moves were developed by skateboard lovers.In many of the tricks,skateboarders seem to resist gravity for an instant but they actually use gravity to make their tricks work.
Skateboarding works best on paved areas such as parking lots.In the 70s and 80s,paved areas with a good downhill slope attracted a growing number of skateboarders.Due to complaints about noise and accidents involving skateboards and pedestrians,skateboarding was banned in many cities.Responding to the need for entertaining skateboarding,some communities built skateboard parks.In recent years,skateboarding has become more popular than ever before.
What is responsible for the fame of skateboarding?Gravity.Teens love to experiment with the forces of gravity.Any object with mass has gravity.Gravity gives us"weight".More significantly,gravity causes acceleration or in skateboarding terms,"speed"when moving downward from a hill or ramp(坡道).When skateboarders are standing at the top of a ramp or hill,their weight is transformed into kinetic(运动的)energy as the skateboarder takes off down the hill.Gravity accelerates the skateboarder downhill.Gravity is what keeps the skateboarder moving and it is also what keeps skateboarding swift and exciting.

分析 本文按时间顺序,写了滑板的发展史.滑板从最初将滚轮连接到一个板上,到后来减少噪音完美利用重力使滑板更快捷也经历了漫长的阶段.
解答 60.C.细节理解题.根据一到三段的关键词"In 1962""In 1973""In the 70s and 80s"可知,文章按时间顺序,写了滑板的发展史.故选C.
61.C.细节理解题.根据第一段"In 1962,a surfer attached roller skate wheels to a board and began selling the skateboards to other surfers"可知,在最初,滑板滚轮被连接到一个板上.故d项按时间应放在第一位.根据后文"In 1973,another California surfer designed a skateboard with plastic wheels"可知,接下来的1973年,玩家就把塑料轮子用在了滑板上.故B项紧随其后.故选C.
62.A.细节理解题.根据文章"Gravity accelerates the skateboarder downhill."可知,重力使滑板下山时的速度更迅速,越来越快.故选A.
63.D.细节理解题.根据文章"What is responsible for the fame of skateboarding?Gravity""Gravity accelerates the skateboarder downhill"可知,是重力造就了滑板,也是重力能让滑板更迅速.故重力使滑板的关键.故选D.
点评 本文是考察学生历史文化类阅读理解文章.这类文章常涉及历史、文化、法制、宗教等方面的文学艺术、发明创造、文化遗产保护、宗教与文化、风俗与习惯、道德与法制、中外文学名著节选、等等.这类材料的命题点往往落在主旨大意题、事实细节题上.
