分析 北欧海盗是第一批到达美洲的欧洲人.他们在第八和第十世纪之间控制了北欧的海洋和海岸.公元900年左右,有很多地方在北欧维京人选择住的地方.公元982年,一个名叫Eric the Red 的人决定进一步向西,有多达10000的维京人住在冰岛.根据冰岛和挪威的记载,Eric the Red 被迫离开冰岛因为他犯了谋杀罪.Eric到达格陵兰岛发现人们可以居住在他登陆的地方.他回到冰岛和格陵兰岛,告诉人们跟他回去.埃里克再次起航,25艘船中只有14艘到达了格陵兰岛.

解答 The Vikings were the first Europeans∧reach America.The Vikings were a group of people which ancestors came from Scandinavia.They controlled the seas and coasts of Northern Europe between the 8th and 10th centuries AD.By around 900 AD,there had many places in Northern Europe where the Vikings chose to live.In 982 AD,when a man was  called Eric the Red decide to set sail further west,there were as much as 10,000 Vikings living in Iceland.According as the old stories of Iceland and Norway,Eric the Red was forced to leave Iceland so he dad committed a murder,for which he got into troubles.Eric reached Greenland and discovered that people could live in the place where he landed.He returned to Iceland and told people to go back with him to Greenland.Eric set sail once again,this time with 25 ships,of which only 14 made them to Greenland.
详解:
1.reach前面加to;考查动词不定式,此处用不定式短语做后置定语修饰名词the first Europeans.
2.which改为whose;考查定语从句,先行词为a group of people,故用whose在从句中作ancestors的定语.
3.had改为were;考查there be句型.There不与have连用,此处用were构成there be句型,故把had改为were.
4.去掉was;考查分词作定语,man 与 动词call存在逻辑上的动宾关系,故把was去掉,用过去分词形式作后置定语.
5.decide改为decided;考查动词的时态,本文讲述过去发生的事情,故用一般过去时.
6.much改为many;考查近义词辨析,much修饰不可数名词,many修饰可数名词,此处修饰10,000 Vikings,故用many.
7.as改为to;考查介词,according to 是固定搭配,意为"根据…".
8.so改为because;考查连词,结合上下文分析句意为"Eric the Red被迫离开冰岛,因为他犯了谋杀罪",故用because引导一个原因状语.
9.troubles改为trouble;考查固定短语,get into trouble是固定搭配,意为"陷入困境,遇到麻烦".
10.them改为it;考查代词,make it 是固定短语,意为"完成,到达".

点评 通过快速阅读短文了解短文的基本大意,再分析句子间的结构关系,从词义,词性,固定短语,句式结构等方面去找文中存在的错误加以修改.
