Ⅰ.阅读理解

A

Despite growing up in Croydon and Liverpool，neither Grace nor Paul felt at home in the city.After meeting at Staffordshire's Keele University，they fell in love with Skye on a geology field trip in 1979.

“The island is only 50 miles north to south，but the variety of terrain(地形) and wildlife is impressive，” says Paul.

Grace adds，“We both loved Gavin Maxwell's Ring of Bright Water and were really passionate about otters(水獭)．It was our dream to get away from the rat race，get married and run wildlife holidays and courses on Skye.”

Five years and 29 loan applications later，they moved to Skye.They were relieved to say goodbye to crowds and traffic and found that the island (population: about  20,000)  attracts like­minded people.“A lot of musicians and craftspeople move here，looking for peace，” says Grace.

After locals started bringing them injured animals，they built a wildlife hospital and have since cared for 170 otters.Paul has gained a PhD in otter ecology and they've set up the International Otter Survival Fund (otter.org)，which supports conservation projects worldwide.

Their three kids had carefree childhoods in a tight­knot community.“We could give them lots of freedom because people watch out for each other's children here，” Grace explains.

She continues，“We go to Inverness (a town in northern Scotland) about once a year for a concert，but otherwise everything we want is here.You have to be mentally and practically self­sufficient.We built a metal shed (小屋)，but that took off in the 90 mph winds. Anything not built solidly will leave.

It's often very dark and wet from November to  March，which can be quite depressing.If there's   wind and rain at the same time，no amount of waterproof clothing will keep you dry.But we make up for it in the summer.With the long days，there's nowhere better.”

Paul concludes，“There's something so special about living here and having a sense of belonging.”

答案：C

B

“De­extinction”， the idea that extinct (绝种的) animals can be brought back through cloning or genetic (基因的) engineering，has attracted the interest of a small group of scientists. The topic has made the cover of National Geographic Magazine. Supporters say they are doing it for moral reasons and because we “miss” the extinct animals. They blame human exploitation (such as trapping，hunting, habitat destruction )  of the extinct animals,  but their plans, though they sound exciting, are exploitation in another form.

Considering the imperfect science of cloning,  de­extinction would  cause  animals  suffering.  Most  animals  born  of  such experiments would suffer serious diseases, dying soon after birth or having a shortened lifetime. Spanish and French scientists worked for years to bring the Pyrenean ibex, a species of wild goat, back from extinction by cloning.  In 2009,  they  succeeded only in producing a sick baby goat that died 10 minutes after birth. For these animals to be born, other animals would live in captivity, in a lab or elsewhere, and serve as mother substitutes (代用品)，routinely having operations as part of the cloning process.  For example, elephants would be kept in captivity to carry woolly mammoth (猛犸)  babies for nearly two years. Such experiments often lead to other animals' unhappiness as well.

If extinct animals are successfully brought back, where would  they go? Their original habitats have developed and changed without  them. They are unlikely to survive in the natural environment, but, if  they do manage to survive, they will affect their environment in  unpredictable ways, presenting a new threat to the ecological system. If  the animals born through de­extinction are stuck in zoos and museums instead, what good is that? It is exploitation, not a solution.

It would be better to apply creative thinking about protection to the real­life problems of today's world. De­extinction takes attention away from the difficult situation of endangered animals. Discussions about woolly mammoth cloning do nothing to stop the illegal killings of endangered wild African elephants. Money would be better used to prevent human conflict with wildlife and their ecosystems.

Let's keep de­extinction in the world of science fiction, learn from our failed past, and protect wild animals and their habitats for the future.

[语篇解读]　本文为一篇议论文。通过克隆或基因工程使已经灭绝的动物“复活”引起了一些科学家的兴趣，但这种做法对于现存的动物及生态环境等不一定有利。

4．The underlined word “it” in Paragraph 1 refers to “        ”．

A．de­extinction

B．cloning or genetic engineering

C．exploitation

D．National Geographic Magazine

解析：词义猜测题。根据第一段第一句可知“de­extinction”指的是“通过克隆或基因工程使已灭绝的动物重生”。再结合第三句(支持者们说他们这么做是出于道德)，由此可见画线的it指的就是“de­extinction”，故答案为A项。

答案：A

5．In Paragraph 2, examples are given to show that       .

A．modern elephants are related to woolly mammoth

B．scientists should improve the cloning process

C．de­extinction does harm to some animals

D．it's possible to bring back extinct animals

解析：推理判断题。第二段的主题句为第一句话，即Considering the imperfect science of cloning，de­extinction would cause animals suffering.然后作者用举例的方法说明了这一道理，由此可见本题答案为C项。

答案：C

6．What might happen if extinct animals come back to the wild?

A．The problem of extinction will be solved.

B．They will live in their original habitats.

C．The balance of nature may be disturbed.

D．More endangered animals will be saved.

解析：细节理解题。根据第三段中的“if they do manage to survive，they will affect their environment in unpredictable ways，presenting a new threat to the ecological system”(如果它们真的生存下来了，它们会以不可预知的方式影响它们的生存环境，从而对生态系统造成一个新的威胁)可知答案为C项。

答案：C

7．According to Paragraph 4, de­extinction may         .

A．prevent the illegal killings of African elephants

B．make people care less about endangered animals

C．prevent the conflict between humans and animals

D．raise public awareness of protecting animals

解析：细节理解题。根据第四段中的“De­extinction takes attention away from the difficult situation of endangered animals.”可知答案为B项。

答案：B

Ⅱ.阅读七选五

Everyone makes mistakes.　1　 Making a mistake at work, however, can be more serious. It may cause problems for your employer and even affect the company's bottom line. Evil consequences will finally come down to you. Simply correcting your mistake and moving on may not be an option. When you make a mistake at work，your career may depend on what you do next.

Admit your mistake.

Tell your boss about your mistake immediately.  The only exception is that you make an insignificant error that will not affect anyone. Otherwise, don't try to hide your mistake. 　2　

Present your boss with a plan to fix your mistake.

When you go to your boss to admit your mistake, you must have a plan for correcting it. Present your plan clearly. Tell your boss how long it will take to carry out your plan and if there are any costs involved.

Don't blame anyone else for your mistake.

　3　 Encourage those who may share responsibility to follow your lead in admitting to your boss.

　4　

There's a big difference between admitting your mistake and beating yourself up about it. Take responsibility but don't blame yourself for making it, especially in public.

Correct your mistake on your own time.

If you have to spend extra hours at work to correct your mistake, don't expect to be paid for that time.　5　

A．Apologize for your mistake but don't beat yourself up.

B．Usually you can correct your error or just forget about it and move on.

[语篇解读]　本文是一篇说明文，主要介绍了中国书法的起源及特点。

1．解析：考查冠词。根据形容词最高级most important可知，空处需用定冠词the，此处意为“最重要的艺术形式之一”。

答案：the

2．解析：考查代词。修饰名词应该用形容词性物主代词，所以填入its。

答案：its

答案：is needed

10．解析：考查名词。此处指“坚持练习这门艺术能培养个人的性格而且对健康大有好处”，形容词great后应用名词benefit。
