When sevenyearold Sky Nockels learned that black rhinoceroses (犀牛) were an endangered species, he decided to do something to help them. He raised money to adopt (收养) a black rhino named Imara at the Great Plains Zoo in South Dakota. By adopting Imara, Sky helps the zoo take care of the rhino’s needs, such as food and a good habitat.

Sky has been a summer camp member at the Great Plains Zoo since he was three. There he and other kids learnt about the animals and did projects for them. “We made juice drinks for the bears,” says Sky. “They enjoyed them.”

Now that Sky is older, he is playing an even more active role in the care of the animals. Since black rhinos are one of Sky’s favorite animals, he decided to adopt Imara first. “I adopted a Grevy’s zebra named Demani, too, for my little brother Alexander,” he says.

Sky raised money to help care for the animals he wanted to adopt. He promised to raise $75 for his rhino and $25 for Alexander’s zebra. To earn the money, Sky and his grandfather planted a vegetable garden. Sky planted seeds (种子), watered, and cleared the grass. When the time came, he harvested the vegetables and sold them in front of his parents’ store.

When Sky’s friends heard about this, they brought vegetables from their parents’ gardens to sell, too. With the help of his friends, he earned enough money to keep his promises.

Sky is one of the youngest people to adopt an animal at the Great Plains Zoo. He cares about the animals and plans to plant and sell vegetables again this summer to help them. “I hope other children do something to help animals, too,” he says.

【1】 The passage is written mainly to ________.

A. explain why rhinos are endangered

C. tell a story about how a kid helps animals

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

I am a strong believer that if a child is raised with approval (认可) he learns to love himself and will be successful in his own way.

Several weeks ago, I was doing homework with my son in the third grade and he kept standing up from his chair. I kept asking him to sit down, telling him that he would concentrate (集中注意力) better. He sat but seconds later, as if he didn’t even notice he was doing it, he got up again. I was getting angry, but then it hit me: I started noticing his answers were much quicker and right when he stood up. Could he concentrate better while standing up?

This made me start questioning myself and what I had been raised to believe. I grew up to believe that a quiet child was more likely to succeed. This child would have the ability to study hard, get good grades and become someone important in life. Kids that were active and loud would only be losers.

Now people perhaps come to realize that their kids are born with their own sets of DNA, and all they can do is loving and accepting them. As parents, throughout their growing years and beyond that, we need to guide them and help them find their way.

I have stopped asking my son to sit down and concentrate. Clearly, he is concentrating, just in his own way and not mine. We need to accept our kids, and heir ways of doing things. There is nothing sweeter than seeing our children being themselves. It makes us happy and that’s just the way I want my kids to live a happy life.

【1】The author tried to keep his son seated so that ________.

A. he couldn’t disturb the author

B. he could keep silent in the room

C. he could finish his homework on time

D. he could pay more attention to his study

【2】 Encouraged by the example of his son, the author began to doubt ________.

A. the importance of parents

B. the old education methods

C. the good grades of some kids

D. the love between kids and their parents

【3】What does the author think of teaching children?

A. Encouragement is important.

B. Children shouldn’t be punished.

C. A fine example is necessary in the school.

D. Children can’t be taught in the same way.

【4】In the opinion of the author, children should ________.

A. have no freedom

B. have their own style

C. learn from their friends

D. be friendly to their parents

材料一：

2011年1月1日8点整，中央电视台纪录频道正式开播，信号覆盖全球。作为中国第一个国家级的专业纪录片频道，也是第一个从开播之始就面向全球采用双语播出的频道，它向世人亮出了拥有人文精神的中国影像。央视纪录频道在内容编排上进行了详细的规划，主要呈现四大主体内容、六大主题时段的播出特点，以期达到规模化的播出效应。央视纪录频道同时采用国际纪录片频道的通行方式，淡化栏目概念，强化大时段编排，以主题化、系列化和播出季的方式，提升自身的影响力和美誉度。

（摘编自杨玉洁等《真实聚焦：2010~2011中国纪录片频道运营与纪录片产业发展纪录》）

材料二：

注：群众构成反映的是收视人群的构成，回答了“谁在看该频道”的问题。集中度是目标观众收视率与总体观众收视率的比值，表示的是目标观众相对于总体观众的收视集中程度，能够回答“谁更喜欢收看这个频道”的问题；集中度的比值大于100%，表示该类目标观众的收视倾向高于平均水平。

材料三：

在制播运营模式方面，央视纪录频道实行的是频道化运营模式。央视是纪录片的主要制作基地。制作出的精品节目数量众多。当然，频道化运营模式也有其自身的劣势，劣势在于频道可以调动的资源非常有限，其融资渠道、产品设计、人财物资源调度都会受到种种限制。央视纪录频道目前正积极推进制播分离模式，节目制作以社会招标、联合制作、购买作为主要方式，并辅以自制精品，为建立较为健全的制作管理模式做好准备。

（摘编自张同道等《2011年国家纪录片频道发展报告（下）》）

材料四：

总部位于美国首都华盛顿的国家地理频道是一个全球性的付费有线电视网。目前，国家地理频道已经以34种语言转播至全球166个国家和地区逾2亿9千万用户。作为一个纯纪录片频道能够取得如此卓越的成就，除了高质量、高观赏性的节目内容之外，与其频道自身的制播运用模式是分不开的。其制播运营模式如下：有线电视系统是在地方政府的批准下由有线电视系统运营商投资建立的，有线电视系统直接面向订户收取费用，有线电视系统运营商是指拥有并运营有线电视系统的企业实体。有线电视节目提供商为有线电视系统运营商提供节目。具体到国家地理频道而言，美国国家地理电视公司以及其他渠道承担提供片源的任务；国家地理频道承担的是节目制作等任务，即让来自国家地理电视公司等渠道的单个的片源变成有机结合的整体，适于在电视上播放；康卡斯特电信公司作为有线电视系统运营商，则承担把电视信号传送到千家万户的电视机上的技术性播出任务。

（摘编自楚慧萍《多元延伸，有机互动——美国国家地理频道运营模式初探》）

C．2011年，在71个大中城市的观众调查中，中央电视电台纪录频道观众构成最高的三类人群分别是：男性、45~54岁以及高中学历。

【3】根据上述材料，概括说明中央电视台纪录频道开播初期与美国国家地理频道在制播运营模式方面的不同。

阅读下列短文，从每题所给的四个选项 （A 、B 、C 和 D ）中，选出最佳选项。

A recent announcement by scientists that they have successfully cloned the first human embryo(胚胎) has caused much debate and has shocked many people around the world. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable tissues(组织) and organs that could be used to save human lives. On the other hand, many people, including some scientists, disagree and fear that if mankind interferes with (干涉) nature in this way, they may be on their way to producing a real-life Frankenstein's monster.

Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly—the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were angry because they thought cloning would create more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific breakthrough.

The Scottish scientist who created Dolly, Ian Wilmut, is shocked that some scientists are now considering cloning human beings. Although he researches cloning, he has never thought of creating copies of humans. Instead, he thinks the scientists should concentrate on creating new tissues and organs that could eventually be used to cure diseases like cancer. However, some people consider that cloning human embryos with the intention of destroying them shows no respect for human lives.

While cloning human embryos is illegal in many countries, some scientists are already pushing ahead with the research so as to deliver a cloned human baby. Severino Antinori, an Italian doctor, is one of the leaders in this field of research. He has declared that he wants to be the first to clone a human being.

In China, scientists have focused their efforts on cloning animals, as well as stem cells to be used in medical research. China has succeeded in producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.

【1】Which of the following statements about cloning is TRUE according to the passage?

A. Cloning technology can only be applied to animals.

B. A cloned animal can live longer than a normal one.

C. People all over the world are happy about the birth of Dolly.

D. Cloning can produce valuable tissues and organs to cure human diseases.

【2】The reasons why some people disagree with cloning include the following EXCEPT that .

A. cloning may produce a real-life Frankenstein's monster

B. cloning might create more diseases in the animal world

C. cloning human embryos shows no respect for human lives

D. cloning can't help those who want to clone their dead children

【3】Who is in favor of cloning human beings?

A. Ian Wilmut.

B. Severino Antinori.

C. The author.

D. The Chinese scientists.
