颞骨骨折最常见的类型是（）
A.纵行骨折
B.横行骨折
C.混合型骨折
D.开放型骨折
E.岩尖骨折
参考答案：A
解析：颞骨纵行骨折最常见，占70％～80％，多系颞部和顶部受到撞击所致。骨折线与岩部长轴平行，常起自颞骨鳞部，通过外耳道后上壁、鼓室天盖，沿颈动脉管到颅中窝底的棘孔或破裂孔附近。因骨折线多从骨迷路前方或外侧穿过，故极少伤及内耳，常伴有中耳结构受损。
Lego, the inventor of those colorful bricks that have inspired kids’ imaginations world-wide, has celebrated its 50th anniversary.  On January 28, 1958, a man named Godtfred Kirk Christiansen created the plastic building bricks that can now be found in almost every child’s toy box. The simple building block has become one of the most well-known and popular toys around the world. "The Lego brick continues to be very attractive, because it allows children, and others, to develop their creativity and imagination," said Charlotte Simonsen, a spokeswoman of the Danish Lego company. The company’s building brick allows an infinite number of links. With just two bricks there are 24 different links, and with six, there are 915 million possibilities, according to Lego. A half-century after its creation, more than 400 million children and adults spend five billion hours a year putting the bricks together and pulling them apart. Also, the bricks made today can still interlock with those made in 1958. Lego bricks are not just child’s play: they also attract the interest of adults. South Korean adventurer, Heo Young-Ho, who climbed Mount Everest in 1987, left a Lego toy behind in the snow during his climb. After its great success Lego experienced a severe crisis at the end of the 1990s, hit hard by fierce competition from electronic games. This so-called "Toy of the Century" then suffered a dark period that lasted several years. With great efforts, the company began to prosper again, and in 2006 it earned about 1.5 billion dollars in 130 countries. Seven boxes of Lego are now sold every second around the world, and 19 billion bricks are produced each year: enough to encircle the Earth five times！ 小题1:The Lego bricks have remained popular in the past 50 years as a result of _______.
