A．to be celebrated B．celebrating
C．celebrated D．having celebrated

C．that D．why
解析：选C 考查主语从句。

C．so that D．even if

A．referred to being B．referred to be
C．refer to being D．refer to be
解析：选B 考查refer to和demand的用法。

分析句子结构可知，refer to作the problems 的后置定语，它们之间是被动关系，所以用被动形式。

demand意为“要求”时，宾语从句中的谓语动词常用“(should＋)动词原形”。

故选B项。

(2017·江苏省名校高三入学摸底卷)Mother Nature is a cruel mistress. Why? Read on to find the answer.
Venice
This iconic city is sinking rapidly. The canals that make up the streets of Venice rise 2mm every year, making relics (遗迹) of history go under the surface of water and destroying architecture. Experts warn that without intervention, this city will disappear back into the water at an even faster rate, consumed by rising sea level of melting polar ice caps.
Machu Picchu
These Incan ruins have drawn adventurous tourists into the mountains of South America. The forces of natural erosion (侵蚀) have been accelerated by tourism and this landmark faces severe influence from increasing foot traffic. The Peruvian government recently suggested a cable car that would cut out the intense hike up to the ruins, making the site instantly accessible to millions, but the future of Machu Picchu remains uncertain.
Glacier National Park
Perhaps you've heard that the ice caps are melting? Nowhere is more apparent in the United States than in Glacier National Park. Estimates indicate that the glaciers that are part of the beauty of this national landmark will disappear entirely in the next two decades.
The Great Barrier Reef
Hidden from view beneath the waves, the Great Barrier Reef has been rapidly dying
off. Nearly fifty percent of coral which once occupied a large area is gone, destroyed by pollution and disease.
语篇解读：本文是一篇应用文。

文章主要介绍了世界上濒临消失的几个旅游胜地。

36．What can we learn about Machu Picchu?
A．It has no convenient traffic.
B．It's famous for cable cars.
C．It's well preserved by the locals.
D．It bears a heavy burden of tourism.
解析：选D 细节理解题。

根据Machu Picchu部分中的“The forces of natural erosion (侵蚀) have been accelerated by tourism and this landmark faces severe influence from increasing foot traffic.”可知，旅游业给当地带来了沉重的生存负担。

故选D。

37．What do the above attractions have in common?
A．They all have a long history.
B．They're all threatened by climate change.
C．They're all in danger of disappearing.
D．They're all well­k nown for natural scenery.
解析：选C 推理判断题。

根据Venice部分中的最后一句， Machu Picchu部分中的第二句，Glacier National Park部分中的最后一句及The Great Barrier Reef部分中的最后一句可推知，这几处旅游胜地的共同点是它们都濒临消失。

文章第一段的内容也是暗示，故选C。

B
Sunday, September 24, 2017, was World Heart Day. World Heart Day was first observed in 2000. The World Heart Federation and its member groups in more than one hundred countries organized the celebrations. The World Health Organization and other United Nations agencies provided support for the event. Organizers suggested the event as a way to help reduce the spread of heart disease. The World Heart Federation says heart disease kills about seventeen million people each year. The group urges people to be active and have a healthy diet. It also warns against activities known to enhance a person's risk of heart attacks.
Some of the warnings are directed at children. The World
Heart Federation says about twenty­two million boys and girls
under the age of five are obese —severely overweight.
Children are normally energetic and active. However, two
thirds of all children are not active enough. Such children
greatly increase their risk of becoming obese. They also increase their risk of
developing heart disease.
The World Heart Federation urges greatly parents to keep their children active. One message of World Heart Day is to eat right. Children should eat a healthy and balanced diet. Also, limit sugary drinks, sweets and eating between meals. It also says physical exercise helps to decrease the risk of obesity and keeps a child healthy. Obese children often become obese adults. If you believe your child is too heavy, talk with a health care provider.
The World Heart Federation is also concerned about the effects of tobacco on young people. Parents also should pay attention to those effects in time. It says the younger someone begins to smoke, the greater the chance of a health problem tied to smoking is. Half of the young people who continue to smoke are likely to die later in life from a smoking­related disease.
The group says almost half of all children live with a smoker. It says children who live with a smoker can breathe an amount of tobacco equal to more than two thousand cigarettes. And that is by the time they are five years old. The World Heart Federation also says parents should warn children not to be influenced by tobacco companies. And it says parents who smoke should try to stop.
语篇解读：本文是一篇说明文，先简单介绍了“世界心脏日”，接着重点讲了世界心脏联盟关于帮助孩子降低患心脏病风险的建议。

38．The underlined word “enhance” in Paragraph 1 means “________”．
A．promote B．lower
C．maintain D．avoid
解析：选A 词义猜测题。

根据第一段最后两句可知，此处应是指世界心脏联盟警告人们提防会增加一个人心脏病发作风险的活动。

故画线词意为“增加，提高”。

A．Parents stop smoking when children are present.
B．Children avoid eating between meals to keep healthy.
C．Parents seek help to handle children's weight problem.
D．Heavy children regard exercise as the best way to lose weight.
解析：选C 推理判断题。

根据第三段最后一句可知，如果你认为你的孩子太重了，就找医疗保健服务提供者咨询一下，即父母在处理孩子的超重问题时，可以寻求帮助。

40．What's the author's main purpose in writing the passage?
A．To introduce World Heart Day.
B．To explain the causes of heart disease.
C．To show some children's bad living habits.
D．To persuade parents to protect children from heart disease.
解析：选D 写作意图题。

通读全文可以看出，本文以“世界心脏日”为切入点，重点讲述了世界心脏联盟为父母提供的一些帮助孩子降低患心脏病风险的建议，故本文的主要写作目的就是劝说父母保护孩子避免患心脏病。

C
Cloning has remained a controversial issue since the birth of a sheep named Dolly hit worldwide headlines in 1996. Produced by scientists instead of by nature, Dolly's successful reproduction from an adult female sheep caused fierce debate about the ethics (道德准则) and impacts of cloning. Simply put, cloning is “the creation of an organism that is an exact genetic copy of another”. It has raised serious questions about potential scientific applications, including the prospect of human cloning. Although cloning advocates regard it as a way to help infertile (不能生育的) couples, grow healthy organs for patients awaiting transplants, and possibly cure diseases, those in opposition express their fears.
Despite advances in scientific understanding, humankind remains students of biology, particularly the interworking of living beings. Scientists have by no means mastered cloning, as evidenced by efforts that have regularly resulted in errors or technical failures, including shortened lifespans. Even Dolly was the only lamb that survived to adulthood from 277 attempts, and it reportedly suffered from arthritis and cells that aged faster than those of a normal sheep.
With inbreeding (近亲繁殖), healthy reproduction becomes increasingly difficult, and offspring (后代) often deal with similar problems to those of inbreeding. Life depends on the diversity of genes, which comes from parents having different sets of genes. Using identical (完全相同的)genes to create and recreate life, as is the practice in cloning, weakens an organism's power and adaptation, increasing its sensibility to diseases. Cloning involves copying identical genes and continual inbreeding finally could lead to a species' extinction.
Lastly, cloning opponents object to scientists “playing God” by not only creating life in a laboratory but experimenting on and deciding the fate of that life. Too many unpredictable factors exist. For example, environmental implications may arise from cloning an extinct species, which could disturb ecosystems no longer able to support those species. The spread of cloned animals, especially since Dolly, and related research have also brought the prospect of human cloning to the forefront. From engineering “the
perfect child” to harvesting brain cells, muscl e tissue, and perhaps entire organs from human embryos (胚胎), anti­cloning activists regard scientists as having overstepped their ethical bounds. Despite good intentions on the part of scientists, in this light cloning is seen as a monstrous, Frankensteinesque procedure. Cloning continues, but its future applications remain uncertain. With proponents and opponents finding little common ground, the debate over this research may not be soon settled.
语篇解读：本文是一篇议论文，主要讲述了反对克隆的人对克隆这一做法所带来的问题的担忧。

41．What's the example of 277 attempts used to say?
A．Scientists don't put cloning into good use.
B．Side effects of cloning can't be ignored.
C．Cloning technology hasn't been perfect.
D．Cloning may disturb the ecological balance.
解析：选C 推理判断题。

根据第三段内容可知，尽管科学家在科学认识上取得了进步，但克隆的成功率较低，甚至Dolly也是277次实验唯一的成果，表明克隆技术还不完善，故选C项。

42．What's the influence of inbreeding?
A．Reproducing different sets of genes.
B．Decreasing the diversity of genes.
C．Weakening the organism's sensibility.
D．Speeding the organism's aging process.
解析：选B 推理判断题。

根据第三段第二句“Life depends on the diversity of genes, which comes from parents having different sets of genes.”以及第三段最后一句可知，生命依赖的是基因的多样性，这种多样性来自有不同基因组的父母。

但是近亲繁殖(即克隆)“复制”的是完全相同的基因，而持续的近亲繁殖会导致一个物种的灭绝。

由此可推知，近亲繁殖会减少基因的多样性。

故选B项。

43．What do cloning opponents really mean by saying “playing God”？
A．Cloning is beyond the moral bottom line.
B．Cloning has endangered human existence.
C．Cloning is beneficial to some extent.
D．Experimenting on animals is unreasonable.
解析：选 A 推理判断题。

根据最后一段第一句以及“anti­cloning activists regard scientists as having overstepped their ethical bounds”可知，对克隆持异议的人认为克隆这一做法超出了道德底线。

44．Which can be the best title for the passage?
A．Why is cloning increasingly popular?
B．Why should scientists view cloning objectively?
C．What are the bad effects of cloning?
D．How can animal cloning benefit humans?
解析：选C 标题归纳题。

纵观全文内容可知，作者首先提出克隆这一话题，接下来分析其带来的负面影响，故C项为本文最佳标题。

D
(2017·江苏省四星级学校联考) What day is it today? Tuesday or Thursday? This thought raced through her mind as she sat back with her students going over the lesson that never seemed to end. Didn't I just do this yesterday? Hell, everything seemed to jumble together.
“Miss Smith, can I go to the bathroom？” Jorge asked. How many times have I heard this? She wondered as she abruptly said “Yes” and watched as he raced out of the room.
She gazed at her students while thinking of what she would do after work. Maybe I'll go to the gym or the market for something. Mechanically she continued with her lesson on the letter “a” with her students. “The letter ‘a’ makes what sound？” “a, a, a”， the students sang together going through the empty motions.
The clock dragged away the minutes teasing her with the tediousness of the day. Won't it end? She thought as the phone rang for her room. Sighing she stood up and walked to get to the phone. Picking up the receiver the other voice seemed a hundred miles away. Oh, how I wish I were anywhere but here. Her mind wandered to the exotic (异国的) beach of Cabo, Mexico, where she had spent her last summer break. She still remembered the cool breezes that touched her skin gently as she lay on the gritty sand.
“Miss Smith, did you hear me？” The secretary annoyingly asked her. “Oh, sorry! What did you say？”“Can you send Carla to the office？” the secretary impatiently asked. “Oh, course，” she replied as she hung up the phone.
She turned from the phone and yelled out Carla's name. Carla was one of the many who always seemed so needy in her class this year. “You need to go to the office，” she said. “Why do I have to go？” whined Carla. “It's between you and the office —just go up.” She hastily turned her back as Carla walked out of the room. Like having free school uniforms is the answer.
It would be nice if just once someone called saying something nice or thanking me for all the endless nonsense I have to deal with. With a sigh she walked back to her other students who were clustered (聚集) at the back table patiently waiting for her
return.
The rest of the afternoon blurred into one long endless repetition. Finally the bell rang as a relief. As she led her students out the door, they walked behind her as baby chicks returning to their fold. She noticed that their mother hens clucked to them behind the gate. As she proceeded to walk down the corridor, the air, which rose with the musical tingle of Spanish coloring everything that touched it, greeted her. She watched with a touch of envy as the children left her to return to those homes that probably were filled with laughter and warmth while she would once again return to the same endless state of being bored.
“Mis s Smith, a moment for favor？” She turned her head and noticed the small shriveled man, his brown face lined with a map to places only he knew. “Thanks for helping my grandson Julio to read, encouraging him to open his heart and helping him realize there is hope for him to make it at school，” the gentleman said in his broken English.
She immediately thought of Julio, who was once as unreachable as a hardened walnut (胡桃), slowly cracked to reveal the eager child inside. She thought of the inner struggle Julio must have had as he tried to make sense of the foreign letters and the sudden joy when he had broken the mysterious code. Was the grandfather the same? She looked up at this elderly gentleman and quickly recognized the sameness of the two.
“Thank you, Mi ss Smith！” A weathered hand came out and firmly grasped hers with warmth that radiated from his soul to hers. Just as abruptly he removed his hand and left her. As he walked away she thought of that exotic sun and realized maybe it was closer to her than she thought.
语篇解读：本文是一篇记叙文。

史密斯小姐感觉日复一日的教学有些无聊，盼望着能够度个假，去享受异国的阳光，而一位心怀感激的祖父的话语让她感受到了异国的阳光就在身边。

45．It can be inferred that the students in Miss Smith's class ________.
A．came from poor families
B．had the greatest respect for her
C．were not skilled at English
D．were always making trouble
解析：选C 推理判断题。

根据第三段中的“Mechanically she continued with her lesson on the letter ‘a’ with her students ...‘a，a，a’，the students sang together”可知，孩子的学习还处于读字母阶段，由此可知这些孩子的英语水平不高。

46．What's the meaning of the underlined word “tediousness”？
A．Boredom. B．Fascination.
C．Routine. D．Exhaustion.
解析：选A 词义猜测题。

根据第三段中的“Mechanically she continued with her lesson”和第四段中的“The clock dragged away the minutes teasing her ... Won't it end？”可知，史密斯小姐觉得自己每天都在机械地重复同样的工作，这是很令人厌烦、很单调乏味的。

由此可知，画线词的意思应是“令人厌烦，单调乏味”，与boredom的意思相近。

下文中的“the same endless state of being bored”亦是提示。

47．What can we know about Miss Smith?
A．She wanted a home full of laughter.
B．She was on bad terms with the secretary.
C．She had a deep affection for her students.
D．She didn't gain satisfaction from her work.
解析：选D 推理判断题。

根据文中对史密斯小姐的枯燥、机械的课堂教学工作的描述，以及第七段中的“It would be nice if just once someone called saying something nice or thanking me for all the endless nonsense I have to deal with.”可知，史密斯小姐并没有从她的工作中得到满足。

48.Why was the old man grateful to Miss Smith?
A．She tutored Julio in English for free.
B．She led Julio to a change of his heart.
C．She bought Julio a set of school uniform.
