A

I was four, playing outside in the humid Kentucky air. I saw my grandfather’s truck and thought, Granddad shou ldn’t have to drive such an ugly truck. Then I ___1___(spy) some paint. Idea!

He could have blamed me. Instead, he lifted my little soul.

【答案】1. spied

2. looking

3. prettiest

4. through

【解析】

这是一篇记叙文。文章讲述了作者小时候和爷爷的故事。

【1题详解】

考查时态。句意：然后我看到了一些油漆。全文时态都是一般过去时态，动词应使用一般过去式。故填spied。【2题详解】

考查非谓语动词。句意：完成我的杰作后我就来到屋顶，这时爷爷走过来，看着他的卡车，十分惊讶。分析句子结构可知，look at his truck作Granddad的定语，look与Granddad之间是主动关系，应使用现在分词形式。故填looking。

【3题详解】

考查形容词比较等级。句意：Angela，那是我见过的最漂亮的卡车。“the +形容词最高级+可数名词+that I’ve seen/heard/known”意为“我见过的/听过的/知道的最……的……”,是形容词最高级的常见用法。故填prettiest。

【4题详解】

考查介词。句意：有时，我觉得成年人应该通过孩子的目光去看待事物。结合句意，后面的短语“a child’s eyes”是用来说明“see things”的方式，即“通过孩子的双眼看待事物”。故填through。

B

阅读下列短文，根据短文内容填空。在未给提示词的空白处仅填写1个适当的单词，在给出提示词的空白处用括号内所给词的正确形式填空。

How do you fight a coral-killing starfish? With a starfish-killing robot, of course. In Australia, researchers

___5___(test) a robot that kills starfish. Specifically, the robot targets a large starfish ___6___(call) the

crown-of-thorns(长棘海星). The animal gets its name from its sharp, poisonous spines(刺). The robot uses cameras to search the seafloor for the starfish. Then it swims close to the animal and uses an extendable arm to inject it with poison. Soon, it is hoped ___7___ scientists can put the robot to work to protect the Great Barrier Reef. Then the starfish won’t seem so tough anymore.

【答案】5. are testing

6. called

7. that

【解析】

这是一篇说明文。文章介绍了澳大利亚人用机器人对付海星，以保护当地的珊瑚礁。

【5题详解】

考查时态。句意：在澳大利亚，人们正试验用一种机器人来消灭海星。这是一篇介绍性的文章，测试机器人的行动是当下正在进行的，应使用现在进行时态。故填are testing。

【6题详解】

考查非谓语动词。句意：特别的是，机器人的目标是一种名为长棘海星的大型海星。分析句子结构可知，call the crown-of-thorns是starfish的定语，starfsh与call之间是被动关系，应使用过去分词形式。故填called。【7题详解】

考查主语从句。句意：科学家有望不久之后将这种机器人用于保护大堡礁的工作中。分析句子可知，it是形式主语，真正的主语是从句“scientists can put the robot to work to protect the Great Barrier Reef.”，句意完整，成分齐全，that引导主语从句，无词义，不做成分，“it+be动词+分词+that+从句”是常见句型。故填that。

C

阅读下列短文，根据短文内容填空。在未给提示词的空白处仅填写1个适当的单词，在给出提示词的空白处用括号内所给词的正确形式填空。

Zoo Awareness Day is a day ___8___ people question the place and value of zoos in the twenty-first century. It is organized by the Captive Animals’ Protection Society, which says zoos are mainly for tourism rather than protecting animals. Even though many zoos promote ___9___(they) as places of education, conservation and research, they are really just a tourist attraction. Zoo Awareness Day is to make people aware that animals in zoos suffer from physical and psychological problems because they are in cages. The protection of ___10___(nature) habitats is the only way to prevent further species decline.

【答案】8. when

9. themselves

10. natural

【解析】

这是一篇说明文。文章介绍了“Zoo Awareness Day”，提醒人们保护动物。

【8题详解】

考查定语从句。句意：动物园宣传日是处于二十一世纪的人们可以质问动物园地位和价值的日子。分析句子可知，a day是先行词，后句结构完整，不缺主语宾语，结合先行词的属性，考虑表时间的关系副词。故填when。

【9题详解】

考查代词。即使很多动物园都标榜自身为集教育、保护和研究于一体的地方，但实际上它们只是旅游景点而已。分析句子可知，这里的they作promote的宾语，就是指动物园自己，应使用反身代词。故填themselves。【10题详解】

考查形容词。句意：对自然栖息地的保护是避免物种进一步减少唯一的方法。这里的nature用来修饰名词habitats，应使用形容词。故填natural。

第二节完形填空(共20小题；每小题1.5分，共30分)

阅读下面短文，掌握其大意，从每题所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。

John Harrison has an enviable job in most people’s opinion. He’s the official taster for Dreyer’s Grand Ice Cream, one of the best-selling ice-cream brands in the U.S.A. On an average day, Harrison has to sample sixty ice creams at the Dreye r’s headquarters. When he isn’t doing that, he travels all over the country, buying Dreyer’s ice cream in supermarkets so that he can carry out spot checks for appearance and flavor. But, no matter how wonderful this job may sound, it is actually quite tou gh. It’s difficult work, requiring discipline, selflessness, and thorough preparation.

Before tasting a sample, Harrison uses his eyes first. If the ice cream doesn’t look attractive, he skips it. Then, he uses a gold spoon instead of one made of wood, plastic, or other metals. This is because regular spoons leave an aftertaste that can dull the taste buds(味蕾). In addition, the temperature of the ice cream may also influence the taster’s taste buds.

When Harrison samples ice cream, he first takes only a small bite of the ice cream, swishes it around in his mouth to introduce it to each of his taste buds, lightly licks his lips, and then gently breathes in so as to bring the smell up through the back of his mouth to his nose. With each step, he carefully sizes up whether the ice cream conveys the ideal balance between dairy sweetness and the flavor of the added ingredients. And last of all, no matter what the ice cream tastes like, he spits(吐) it out, since a full stomach makes for a dull palate(迟钝的味觉).

For Ha rrison, keeping a sharp palate means no onions, garlic, or cayenne pepper. He also doesn’t have any coffee or tea, since these block the taste buds. But to him, this is just a small price to pay for what he calls “the world’s best job” .

Harrison’s family has been in the ice-cream business for four generations, and Harrison himself has spent almost his whole life in it as well. Yet, he has never lost his love of the cold, creamy sweetness. He orders ice cream in restaurants for dessert, even when he’s not a t work. On these occasions, he swallows the ice cream, taking in about a liter a week. Though he has gained some weight over the years he’s been with Dreyer’s, he couldn’t care less. “Who would trust a skinny ice-cream taster?” he jokes.

34. What is forbid den in Harrison’s job?

A. Doing shopping.

B. Eating the ice cream.

C. Using gold spoons.

D. Skipping the ice scream.

35. What can we learn about Harrison?

A. He learned his work skills from his family.

B. His job affects his appetite for the ice cream.

C. He is willing to give up something for his job.

D. He has to gain some weight to meet the need of work.

36. What does Harrison think of his job?

A. Creative.

B. Ordinary.

C. High-paying.

D. Proud.

37. What is the main purpose of the passage?

A. To describe Harrison’s job and how he does it.

B. To analyze the reasons why Harrison chose his job.

C. To make suggestions on how to apply for popular careers.

D. To introduce the advantages of working for a best-selling brand.

【答案】34. B 35. C 36. D 37. A

【解析】

【分析】

这是一篇记叙文。文章介绍了John Harrison的令人羡慕的工作——冰淇淋试味，这一职业其实并不像人们想象的那么美好，背后也需要不少付出。

【34题详解】

细节理解题。根据第三段最后一句“And last of all, no matter what the ice cream tastes like, he spits(吐) it out, since a full stomach makes for a dull palate(迟钝的味觉).”可知，试味结束后Harrison是不能吃掉冰淇淋的，必须要吐掉以避免饱腹感对味觉的影响。故选B项。

【35题详解】

推理判断题。根据第四段最后一句“But to him, this is just a small price to pay for what he calls “the world’s best job” .”可知，尽管为了保持味觉敏锐日常生活中需要忌口，但Harrison仍然觉得这份工作无与伦比，作出一些牺牲也可以接受。故选C项。

【36题详解】

推理判断题。根据倒数第二段的But to him, this is just a small price to pay for what he calls “the world’s best job” .并结合最后两段来看，Harrison喜爱自己的工作也将毕生精力投入其中，对于这份工作他是引以为傲的。故选D项。

【37题详解】

推理判断题。文章围绕着Harrison冰淇淋试味这项工作展开，详细描述了工作内容，旨在让读者对这一职业有所了解。故选A项。

【点睛】写作意图考题的主要形式分为考查整篇文章的写作目的和考查某处细节的写作意图。不同的文章写作目的也不尽相同，通常可以分为这么三种：1.常见于故事类的文章：讲述一段有趣或不同寻常的经历。

2.常见于广告类的文章：推销一种产品或服务；吸引游客/读者/观众等。

3.常见于科普类、新闻报道类、文化类或社会类的文章：向读者普及一些信息；报道某人某事；简单介绍某人某事。这类题目主观性较强的阅读理解需要考生具备对事物进行归纳分类的能力，在获取信息事实后，才能将已知细节加以分析，从而得出合理的判断。本文属于第三种类型，主要内容就是冰淇淋试味员Harrison和他的工作内容，其意图就是向读者介绍冰淇淋试味员这份职业和工作内容，提问写作意图的第四小题中，A选项是最贴合的，从而确定答案。

C

In 2012, James Cameron, creator of Avatar and Titanic, became the first person to reach the Challenger Deep. When he arrived at the deepest spot on Earth at 7 miles below sea level, he spent hours mapping the region and taking photos and samples.

“As human beings, we’re drawn to absolutes—the deepest, the highest, the coldest, the farthest,” he says. “And as a storyteller and curious monkey, I just wanted to see what was there.” The answer is obvious—plastic and more. “Our so-called civilizat ion is using the ocean as its toilet,” Cameron says. “Unless this changes, ocean ecosystems are going to continue their rapid collapse.”

Despite decades of environmental studies, the impact of plastic and other forms of pollution on oceans are not entirely understood. Initial studies appear to indicate that ingesting(摄取) them—either directly or indirectly—could cause disease. Plastics can also release poisonous substances into the water, which could potentially impact animal populations.

But plastic is just one of the problems facing oceans that have yet to be fully understood. “Plastic waste in the ocean is horrifying but is only the most obvious of our many deadly waste streams, which include carbon that’s heating the atmosphere and making the ocean acidic, and the run-off nutrients from all the world’s agriculture, which is causing anoxic(缺氧的) dead zones the size of countries,” Cameron says.

Oceans, like the rest of the world, are impacted by the burning of fossil fuels and the release of greenhouse gases like carbon dioxide—about 30 percent of which is absorbed by the sea. This absorption causes ocean acidi?cation, where the pH level is altered to become more acidic. As a result, it’s harder for some creatures to form shells and skeletons and countless species at the base of the food web can struggle to survive, which, scientists say, has the potential to cause huge disruptions to entire ecosystems. Indeed, ocean acidi?cation is thought to have played an important role in Earth’s worst-ever mass extinction event 252 million years ago.

The effect of climate change on the world’s oceans will likely worsen in coming decades. Last June, scientists announced carbon dioxide levels had reached the highest levels since human records began. The last time carbon dioxide levels were this high was during the Pliocene era, between 3 and 5 million years ago, when global temperatures were about 4 degrees Celsius warmer than they are today. Current climate models suggest that if greenhouse gas emissions continue on their current trend, we may be on course to see 4 degrees of warming by 2100.

As a result, understanding the role oceans have on global systems is becoming more and more important.

38. What are the first two paragraphs mainly about?

A. The author’s feelings to the ocean.

B. Cameron’s movies and remarks.

C. The author’s discoveries under the sea.

D. Cameron’s observation and concern.

39. What can we infer from the passage?

A. Several countries are suffering from anoxic dead zones.

B. More concern should have been given to the pollution on oceans.

C. Plastic is supposed to be the most serious environmental problem.

D. Ocean acidification removes the nutrients from agricultural products.

40. What does the underlined word “disruptions” in Paragraph 5 probably mean?

A. Decreases.

B. Destruction.

C. Diseases.

D. Discrimination.

41. Why does the author mention the mass extinction event 252 million years ago?

A. To call on people to protect sea animals.

B. To compare current situations with the past.

C. To explain how serious the ocean problem is.

D. To prove pollution to be the cause of acidification.

【答案】38. D 39. B 40. B 41. C

【解析】

这是一篇说明文。文章由詹姆斯·卡梅隆的一次潜航经历引入，从气候变化、环境污染等不同方面描述了海洋生态系统正在遭受的巨大破坏，告诫人们提高对海洋环境的重视。

【38题详解】

主旨大意题。前两段讲述了大导演卡梅隆潜航至世界上海洋最深处，却看到了许多塑料垃圾。他发声称“Unless this changes, ocean ecosystems are going to continue their rapid collapse.”意为“如果还不做出改变，海洋生态系统将会继续崩塌下去”。这正是他的所观所想。故选D项。

【39题详解】

推理判断题。根据第四段“Plastic waste in the ocean is horrifying but is only the most obvious of our many deadly waste streams, which inc lude carbon that’s heating the atmosphere and making the ocean acidic, and the run-off nutrients from all the world’s agriculture, which is causing anoxic(缺氧的) dead zones the size of countries”可知，塑料垃圾的影响显而易见但也不能忽视其他废物排泄对海洋造成的影响，人们对海洋污染的关注仅仅着眼于塑料垃圾是远远不够的。故选B项。

【40题详解】

As we prepare learners with the skills needed for the 21st century, there is a greater desire to further integrate technology into our classrooms. Whether it’s a K-12 or college classroom, it’s rare to find an environment that does not integrate technology in some form or another. In some cases, online learning has replaced the physical classroom altogether. As educators, we owe it to ourselves and our students to use these benefits. However, while technology offers significant advantages, simply integrating it as an alternative source of delivery or as another means for students to demonstrate their comprehension is not an effective practice.

We must remind ourselves that any form of learning technology should also be guided. These resources are just instruments and require high-quality guided practice from instructors. These instruments, combined with guidance, can afford good instruction, practice and motivation. While technology can positively impact learning outcomes, it may be even more effective for some students if it’s instructor-led and integrated into a well-designed curriculum(课程).

Technology is rapidly changing the educational environment and challenging students to adapt accordingly. It can frustrate students of different generations struggling to learn how to use a learning platform in addition to picking up the actual subject. Some may wonder, “Why should I waste time learning how to create a podcast(播客) when I could simply write the paper?”

It’s a reasonable question. We must not assume students who were raised using technology are always comfortable learning with these tools. A study found that because of tools some students may not have experience using, they may need more direction on how to apply these tools. Students may struggle if an instructor neglects to teach the conceptual basis of the tools. Technology may mean little without appropriate objectives and goals for its use, structures for its application, and trained deliverers.

Educators are also tasked with providing students the skills they need to flourish in a highly competitive and technologically-based workplace. Many of the skills obtained through online classes are valuable professional skills. Students taught how to use multiple learning technologies effectively have a competitive advantage over those who are simply using technology as a method of delivery in the online classroom. Regardless of the subjects we teach, integrating technology gives our students the opportunity to not only learn the content, but also to develop skills useful beyond our classrooms. Technology, when integrated and balanced appropriately with the curriculum and with student needs, can make us more effective as educators.

42. What is important to the learning technology?

A. Instruction and revision.

B. Comprehension and application.

C. Guidance and arrangements.

D. Diversity and flexibility.

43. According to the passage, what should an educator do?

A. Arrange online assignment for students.

The Internet is the largest library in the history of the world and a great resource for anyone seeking information. ___46___ In recent years, plagiarism from online sources has become a serious problem, especially among students.

Original written work and information are protected by copyright laws. Therefore, when you use information you find while doing research, you should always give credit to the person that produced it. To plagiarize is to use ideas that are not your own without giving credit to the original source, or to claim that someone else’s ideas are your own. This is a dishonest practice.

Internet-related plagiarism has become such a problem. ___47___ There are thousands of resources for students who wish only to copy or cheat. However, the Internet also makes it easier for educators to check for plagiarism. Often a simple Internet search for a quote will be enough to expose copying. ___48___ Because copying and pasting(粘贴) is so easy, it is becoming more and more common for well-meaning students to mix up source material with their original ideas. While unintended plagiarism usually happens innocently, it is still a mistake.

___49___Usually, the first step of researching is to gather information. You’d be tter keep a computer document named “References” where you can keep useful information you search on the Internet. Copy and paste the material directly from the document. When you print out parts of the article from the document, print the first page of the article. ___50___ These will help you remember the source of the information. Then print pages that have the information you need. After you finish your assignment, in the same way that you review your work for clarity and mistakes, you need to check that you have matched the quoted information with the correct source. Following these tips, you will avoid mixing up source material with your ideas.

A. It lists details like the name of writer and publication.

B. But doing research on the Internet is not without its risks.

C. This is because it is so easy to find and copy information online.

D. Some educators are more concerned about unintended plagiarism.

E. In addition to dishonesty, plagiarism is a lost opportunity for students.

F. To avoid unintended plagiarizing, managing your sources becomes important.

G. If you use ideas from other writers without quoting from the original work, you’re plagiarizing.

Dear Jim,

____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ _____________________________________________________________________________

Yours,

Li Hua 【答案】Dear Jim,I’m so glad that you’re interested in Chinese poetry! The poem you read was written by Li Bai, one of the greatest poets of the Tang Dynasty. It describes a scene when the poet saw off his friend at Yellow Crane Tower for his journey to Yangzhou. It was the third month by lunar calendar, when all the flowers were in full bloom in spring. What a vivid picture of the beautiful spring scenery! This is the power of Chinese poetry.

I believe you will have a further understanding after you read more Chinese poems. It is spring right now. Just as described in the poem,there are so many places in China that deserve a visit. For example, the city of Wuhan, where Yellow Crane Tower is located, is exactly a place suitable for a spring tour. As the capital city of Hubei Province in central China, Wuhan is in its most beautiful season now. Blooming flowers and the countless historical sites are indeed a feast to the eye!

I hope we can tour the city together in the near future!

Yours,

Li Hua 【解析】
