Grammar and Vocabulary Section A Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.‎ Brain implant lets man with paralysis move and feel with his hand A brain implant has restored movement and a sense of touch in the hand of a man with a severe spinal cord injury.‎ Patrick Ganzer at Battelle Memorial Institute in the US and his colleagues have developed a brain-computer interface (BCI) that ___1___ (allow) 28-year-old Ian Burkhart to grasp and feel objects again.‎ Burkhart has a severe upper spinal cord injury and has complete paralysis in his hands and legs, ___2___ can move his elbows and shoulders. He had a brain implant inserted in 2014 as part of research aiming to restore movement in ___3___ right arm.‎ The BCI uses the implant ___4___ (record) brain activity that is sent to a processor that decodes these signals into movements, which in turn feed in to bands around the forearm which electrically activate his hand muscles.‎ ‎“We’ve made a lot of progress in the last six years: he can play [the video game] Guitar Hero, swipe a credit card and do about 20 different hand grips,” says Ganzer.‎ But because Burkhart had no sensation in his hands, he previously had no sense of touch or pressure when ___5___ (grasp) objects, and if blindfolded, was not able to detect small objects such as a pencil.‎ The researchers discovered that ___6___ Burkhart’s hand cannot feel anything, the brain implant stills registers a faint sensory signal when he touches an object.‎ They boosted this signal by incorporating a band around the bicep which vibrates when Burkhart’s hand receives sensory information.‎ - 27 -‎ As a result, Burkhart is able to detect objects by touch alone. The BCI is also able to detect different levels of touch and adjust the strength of Burkhart’s hand movements depending on the object – a light grasp, for example, for a paper cup.‎ The researchers believe it is the first BCI ___7___ can simultaneously restore movement and touch.‎ When the brain implant was inserted, it ___8___ (intend) solely for controlling movement, but the ___9___ (add) touch is possible because there is some overlap ____10____ the sensory and motor areas in Burkhart’s brain, says Ganzer.‎ ‎【答案】1. has allowed ‎ ‎2. but 3. his ‎ ‎4. to record ‎ ‎5. grasping ‎ ‎6. (al)though ‎ ‎7. that 8. was intended ‎ ‎9. added 10. between ‎【解析】‎ 这是一篇说明文。文章主要说明了一名28岁严重脊髓损伤的男子Ian Burkhart的大脑植入物恢复了他的运动能力和手的触觉。文章说明了为了达到这一目的研究人员所采取的努力。‎ ‎【1题详解】‎ 考查动词时态。句意：美国巴特尔纪念研究所的Patrick Ganzer和他的同事开发了一种脑机接口（BCI），使28岁的Ian Burkhart能够再次抓住并触摸物体。此处强调过去发生的动作对现在产生的影响，应用现在完成时，且主语为a brain-computer interface (BCI)，助动词用has。故填has allowed。‎ ‎【2题详解】‎ 考查连词。句意：Burkhart的上段脊髓严重受伤，手和腿完全瘫痪，但肘部和肩膀可以活动。结合上下文语境可知为转折关系，故用连词but。故填but。‎ ‎【3题详解】‎ 考查代词。修饰后文right arm，应用形容词性物主代词his，表示“他的右臂”。故填his。‎ ‎【4题详解】‎ 考查非谓语动词。根据短语use sth. to do - 27 -‎ ‎ sth.表示“用某物做某事”，后跟不定式。故填to record。‎ ‎【5题详解】‎ 考查非谓语动词。在when连接的状语从句中，常省略跟主句相同的主语和be动词。从句完整为when (he was) grasping objects, and if blindfolded, was not able to detect small objects such as a pencil。故填grasping。‎ ‎【6题详解】‎ 考查连接词。句意：研究人员发现，尽管Burkhart的手感觉不到任何东西，但当他触摸物体时，大脑植入物仍然会记录微弱的感觉信号。此处为让步状语从句，表示“尽管”可用although或though引导。故填(al)though。‎ ‎【7题详解】‎ 考查定语从句。分析句子结构可知，此处为定语从句修饰先行词BCI，且先行词在被序数词the first修饰在从句中做主语，只能用关系代词that。故填that。‎ ‎【8题详解】‎ 考查动词时态及语态。本句主语与谓语动词构成被动关系，且根据上文When the brain implant was inserted可知为一般过去时，主语为it，谓语动词用单数。故填was intended。‎ ‎【9题详解】‎ 考查非谓语动词。分析句子结构可知，add在句中作非谓语动词，与逻辑主语touch构成被动关系，故用过去分词。故填added。‎ ‎【10题详解】‎ 考查介词。根据短语between…and…表示“在……之间”。故填between。‎ Section B Directions: Fill in each blank with a proper word chosen from the box.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.‎ A 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 civilization 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 - 27 -‎ ‎ 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) 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 acidification, 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 acidification 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.‎ ‎36. 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.‎ ‎37. What can we infer from the passage?‎ - 27 -‎ 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.‎ ‎38. What does the underlined word “disruptions” in Paragraph 5 probably mean?‎ A. Decreases. B. Destruction.‎ C. Diseases. D. Discrimination.‎ ‎39. 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】36. D 37. B 38. B 39. 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。‎ ‎【36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。‎ ‎【37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 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”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。‎ ‎【38题详解】‎ 词义猜测题。A. Decreases减少B. Destruction破坏C. Diseases疾病D.‎ - 27 -‎ ‎ Discrimination歧视。分析划线词所在句子可知，一些生物难以生长甲壳和骨骼，许多的处于食物链底端的生物生存也十分艰难，这对整个生态系统无疑是造成破坏的。故选B项。‎ ‎【39题详解】‎ 推理判断题。第五段最后一句“Indeed, ocean acidification is thought to have played an important role in Earth’s worst-ever mass extinction event 252 million years ago.”提及了两亿五千二百万年前的物种大灭绝，海洋酸化在其中扮演了重要角色，时下我们面临的情况也在朝着这个方向演进，这正是在说明情况的严峻性。故选C项。‎ B Enjoy an amazing time in Lake Tahoe, CA with the fantastic show, Magic Fusion!

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 - 27 -‎ ‎ 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.

Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.‎ The Internet is the largest library in the history of the world and a great resource for anyone seeking information. ___47___ 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. ___48___ 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. Some educators are more concerned about unintended plagiarism. 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 better keep a computer document named “References” where you can keep useful information you search on the Internet. Copy and paste the material directly from ‎ - 27 -‎ 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. In addition to dishonesty, plagiarism is a lost opportunity for students.‎ E. To avoid unintended plagiarizing, managing your sources becomes important.‎ F. If you use ideas from other writers without quoting from the original work, you’re plagiarizing.‎ ‎【答案】47. B 48. C 49. E 50.

Summary Writing ‎51.Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.‎ ‎“It is important for us to understand that the computing platforms of today will not be able to sustain at-scale implementations of AI algorithms on massive datasets,” said Thirumalai Venkatesan, one of the authors of a paper published in Applied Physics Reviews, from AIP Publishing.‎ ‎“Today’s computing is way too energy-intensive to handle big data. We need to rethink our approaches to computation on all levels: materials, devices and architecture that can enable ultralow energy computing.”‎ Brain-inspired electronics with organic memristors could offer a functionally promising and cost-effective platform, according to Venkatesan. Memristive devices are electronic devices with an inherent memory that are capable of both storing data and performing computation. Since memristors are functionally analogous to the operation of neurons, the computing units in the brain, they are optimal candidates for brain-inspired computing platforms.‎ Until now, oxides have been the leading candidate as the optimum material for memristors. Different material systems have been proposed but none have been successful so far.‎ ‎“Over the last 20 years there have been several attempts to come up with organic - 27 -‎ ‎ memristors, but none of those have shown any promise,” said Sreetosh Goswami, lead author on the paper. “The primary reason behind this failure is their lack of stability, reproducibility and ambiguity in mechanistic understanding. At a device level, we are now able to solve most of these problems.”‎ This new generation of organic memristors is developed based on metal azo complex devices, which are the brainchild of Sreebata Goswami, a professor at the Indian Association for the Cultivation of Science in Kolkata and another author on the paper.‎ ‎“In thin films, the molecules are so robust and stable that these devices can eventually be the right choice for many wearable and implantable technologies or a body net, because these could be bendable and stretchable,” said Sreebata Goswami. A body net is a series of wireless sensors that stick to the skin and track health.‎ The next challenge will be to produce these organic memristors at scale, said Venkatesan.‎ ‎“Now we are making individual devices in the laboratory. We need to make circuits for large-scale functional implementation of these devices.”‎ ‎【答案】The pressing question for many researchers is how to handle the technological revolution. Brain-inspired electronics with organic memristors could offer a functionally promising and cost-effective platform. Since memristors are functionally analogous to the operation of neurons, the computing units in the brain, they are optimal candidates for brain-inspired computing platforms.‎ ‎【解析】‎ ‎【分析】‎ 这一篇概要写作。‎ ‎【详解】写作步骤 ‎1）细读原文。首先要仔细阅读短文，掌握文章主旨。文章说明了许多研究人员面临的紧迫问题是如何应对技术革命。脑灵感电子与有机记忆电阻器可以提供一个功能上有前途和成本效益的平台。由于忆阻器在功能上类似于神经元（大脑中的计算单元）的运作，因此它们是脑灵感计算平台的最佳候选。‎ ‎2）弄清结构，归纳段意。概要写作是写全文概要，不是写某一部分的概要，或者就某些问题写出要点。因此一定要弄清文章结构，归纳文章各段大意。‎ - 27 -‎ ‎3）列出原文要点。分析原文的内容和结构，将内容分项扼要表述并注意在结构上的顺序。在此基础上选出与文章主题密切相关的部分。‎ ‎4）在写作时要特别注意下面几点：‎ ‎（1）概要应包括原文中的主要事实，略去不必要的细节。‎ ‎（2）安排好篇幅的比例，概要应同原文保持协调，即用较多的文字写重要内容，用较少的文字写次要内容。‎ ‎（3）注意要点之间的衔接，要用适当的关联词语贯通全文，切忌只简单地写出一些互不相干的句子，但也不要每两句之间都加关联词语，以免显得生硬。‎ ‎（4）不排斥用原文的某些词句，但不要照搬原文的句子，如果不能完全用自己的话语表达，至少对原文句子做一些同义词替换，如果结构上也能有一些转换会更好。‎ ‎（5）计算词数，看是否符合规定的词数要求。‎ V.
