Passage 2
Questions 6 to 10 are based on the following passage:
In today's extremely connected world, (78)people appear to have more chances to get into contact with one another than ever. Yet societies known as "uncontacted peoples” remain in parts of the world. These are communities with little contact with the wider world. It is estimated that about one hundred groups of uncontacted peoples exist today. In general, these groups remain uncontacted by choice; because of this, it is impossible to know much about their societies.
For example, North Sentinel Island in the Indian Ocean is home to a group that clearly wishes to stay separate from the rest of the world. They are referred to as the North Sentinelese. North Sentinel Island is one of the Andaman Islands, which are part of India. While groups on other Andaman Islands have slowly accepted tourism and development, the North Sentinelese fire warning arrows from their beaches at any boat that approaches their land. Over many decades, gifts and other efforts from outsiders have been rejected. From what little we know about their language, they have probably been isolated for tens of thousands of years.
Why might uncontacted peoples choose to remain isolated? Unfortunately, in many cases these groups' past encounters with the outside world were violent. Former members of uncontacted groups have said that after friends and family were attacked or killed by outsiders, they avoided any kind of contact. Even peaceful contact can have disastrous effects. Many uncontacted groups have never been exposed to diseases, not even the common cold or flu. As a result, they often don't have immunity(免疫力)to these diseases, meaning that even minor contact with outsiders has resulted in deadly outbreaks. It's not surprising, then, that some groups prefer to keep to themselves.
6. What is the passage mainly about?
Societies known as “uncontacted peoples”.
The North Sentinelese.
Encounters with "uncontacted peoples”.
Contact with groups on the Andaman islands.
【答案】A。主旨题。本题要求概括文章的主要内容。A选项是被称为“未接触民族”的社会，B选项是北森蒂纳尔人，C选项是与安达曼群岛上的人群的接触，D选项是与安达曼群岛人群的接触。这篇文章主要介绍了“未接触民族”的生存状况及其与世隔绝的原因，因此A选项为正确答案。
7. What is TRUE of the majority of the Andaman Islands?
They have developed contact with the wider world.
They fire warning arrows at approaching boats.
They reject gifts from outsiders.
They are eager to develop tourism.
【答案】A。细节理解题。本题要求选出有关安达曼群岛多数族群的正确说法。根据文章第二段第四至六句“While groups on other Andaman Islands have slowly accepted tourism and development the North Sentinel ese fire warning arrows from their beaches at any boat that approaches their land.Over many decades，gifts and other efforts from outsiders have been rejected.From what little we know about their language， they have probably been isolated for tens of thousands of years.”， 可知其他安达曼群岛的族群已逐渐接受了旅游和开发，而北森蒂纳尔人依然对外界保持敌意，从语言判断，他们已与世隔绝了数万年。A选项是他们与外界建立了联系，是正确的。B选项是他们向靠近的船只射箭警告，C选项是他们拒绝了外界的礼物，二者都是北森蒂纳尔人所为， 不代表大多数族群， 是错误的。D选项是他们急于发展旅游业， 与文中的slowly accepted tourism不符， 是错误的。
8. From which of the following do people know that the North Sentinelese have been separated for so many years?
Peaceful contact.
The warning arrows.
Their language.
Tourism.
【答案】C。细节理解题。本题问的是从哪个方面可知北森蒂纳尔人与外界隔绝多年。根据文章第二段最后一句“From what little we know about their language， they have probably been isolated for tens of thousands of years."， 可知由于对他们的语言知之甚少， 人们判断他们已经与世隔绝了几万年。正确答案为C。
9. How many reasons are given to explain the isolation of the “uncontacted peoples"?
One.
Two.
Three.
Four.
9.【答案】B。细节理解题。本题问的是作者给出了几个理由来解释“未接触民族”与世隔绝的原因。定位到文章最后一段， 可知作者主要从violent contact和peaceful contact两方面来分析原因， 故正确答案为B。
10. The expression keep to themselves in the last paragraph is closest in meaning to________.
stay separated
guard secrets
stick closely
protect themselves
答案A，词义猜测题。本题要求选出与keep to themselves意思相近的短语。A选项是stay isolated 保持与世隔绝， B选项是guard secrets保守秘密， C选项是stick closely坚守， D选项是protect themselves 保护他们自己。文章最后一句话“It's not surprising， then， that some groups prefer to keep to themselves.“是对本段开头的总结和呼应，意思是一些人群宁愿保持与世隔绝的状态也就不足为奇了。因此正确答案为A
