材料一   16、17世纪时，西欧医生的地位还很低，尽管主要的宫廷医生有很高的经济收入，但医生并不被认为是一个很光荣的职业，直到17世纪中叶，一位绅士还拒绝同一位很有钱的医生的女儿结婚。律师职业虽然不被视为低等，但也不受人尊重。20世纪以后医生和律师是备受欢迎和尊重的职业。

材料二    17世纪上半叶茶叶、咖啡等饮料进入欧美，饮茶和喝咖啡成了上层社会的时尚。18世纪时已有大量的热带水果和蔬菜进入欧洲市场，到了19世纪，比较富裕的家庭的饮食结构逐步趋向合理。

材料三    18世纪，社会低层的人们娱乐活动主要是看斗鸡、斗牛，去小酒店喝劣质的烈性酒。上层人士的消遣有打猎、赛马。赌博是各阶层都普遍参加的活动世纪中叶开始，各种体育活动迅速发展起来，垒球、足球、田径运动纷纷诞生，特别是足球和田径比赛，不仅吸引了许多参加者，而且吸引了更多的观众，成了各阶层人士喜爱的消遣。

材料四  不过在工业化以前的社会中，贫困一般是由于社会生产得不到发展、物质产品不够丰富而产生的。从某种意义上说，消除这种贫困，让每个人都过上富足的生活，恰恰是工业化的目标……工业革命时期，绝大多数工人居住在工厂周围的棚户区中，这里的房屋不但质量差，而且通风、采光、卫生条件恶劣……英国史学家哈里森会说“无须过多地想像我们就可以理解，为什么在19世纪40年代，中等阶级会觉得他们生活在一座被贫困的海洋所环绕的小岛上。无论是在工厂里，在大街上，还是在自己家中，他们总能意识到自己所依赖的穷苦劳工的存在。正如他们自己不止一次所说的，穷人随时都在你的身边。”

Angry Birds has become a worldwide gaming mega hit but how did this game come into existence? Rovio is the name of the company that created angry birds, however, it's not the first game they developed. Surprisingly they have been creating games for several years but had just never broken through into the mainstream the way they did with angry birds. The idea for the game came about in 2009 when the company was looking at different ideas for games which they thought could become popular. It was a simple idea spawned from some sketches(素描) of wingless and legless birds which were angry.

The sketches caught on among the staff who in turn created a unique design which became angry birds. The pigs were added into the game later in the development as an enemy. During this period of development, pig flu was being heavily reported in the news which is where the idea for the pigs appeared.

The basis of the game is very simple and is not unique to angry birds but has been seen in many other games previously. It's a simple physics/puzzle game. The player is given a slingshot and a limited supply of angry birds with different characteristics. Some birds are faster than others while others can be split into multiple birds. You control the trajectory(轨迹) of the birds with the slingshot which launches them towards rickety structures containing your main enemy, the pigs. In order to advance to the next level you must eliminate(消灭) all of the pigs before your birds run out.

Rovio has released several different versions of the game at this point. The original, Seasons, and Rio. Seasons is a collection of holiday themed versions of the game while Rio was a movie tie in for the movie Rio. All versions continue to be updated with new levels which are free to those who have previously purchased the game.
