阅读下列材料,完成下列问题。

材料一 正像达尔文发现有机界的发展规律一样,马克思发现了人类历史的发展规律,即历来为繁芜丛杂的意识形态所掩盖着的一个简单事实:人们首先必须吃、喝、住、穿,然后才能从事政治、科学、艺术、宗教等等……不仅如此,马克思还发现了现代资本主义生产方式和它所产生的资产阶级社会的特殊的运动规律。……一生中能有这样两个发现,该是很够了……   ——恩格斯《在马克思墓前的讲话》

材料二 ……东京的圣诞礼品市场生意清淡了不少,但日本东方出版社近日推出的根据马克思《资本论》改编的漫画,却成为岁末年关最炙手可热的礼物。该书首印2.5万册,上市不过10天便已售罄,并且挤进了畅销书榜单。——据新华社2009年12月20日电

(1)指出材料一中“两个发现”的含义,结合所学知识简析马克思主义诞生的意义。

阅读理解。

     A Scotsman and an Englishman lived next door to each other. The Scotsman owned a hen

and each morning he would look in his garden and pick up his hen’s egg for breakfast. One

morning he looked into his garden and saw that the hen had laid an egg in the Englishman’s garden.

     He was about to go next door when he saw the English-man pick up the egg. The Scotsman

ran up to the English-man and told him that the egg belonged to him because he owned the hen.

The Englishman disagreed because the egg was on his property(财产).

     They argued for a while until finally the Scotsman said, "In my family we normally settle disputes

by the following actions: We kick each other and we compare the time how long it takes us to

get back up. Whoever gets up quicker wins the egg."

     The Englishman agreed to this, so the Scotsman found his heaviest pair of boots and put

them on. He took a few steps back, then ran toward the Englishman and kicked as hard as he

could in his stomach.

     The Englishman fell to the floor, holding his stomach and howling in pain for 10 minutes.

Eventually the English-man stood up and said, "Now it’s my turn to kick you." At this time,

the Scotsman said, "Aye Lad, maybe you should just keep the egg."
