Unit 20 New Frontiers 課時練(一)　閱讀理解組塊專練——練速度 (限時：35分鐘) Ⅰ.閱讀理解 A (2019貴陽監(jiān)測)In no particular order, here are some songs on the Music app of my phone： On a Sunday Afternoon by Lighter Shade of Brown — A student of mine introduced this rap song to me all the way back in the early 1990s, when I was teaching Spanish at a local university. The story in the song takes place not too far from where I live in Los Angeles. Its a good “driving” song, nothing plicated or “deep”． Say Something by A Great Big World — A more recent song about a couple losing contact with each other. The piano part is of very little playing but beautiful. American Pie by Don McLean — Another song from my youth in the 1980s, very popular with almost every American of my generation. It retells some of the key events of the middle 20th century, a song of happy memories of the past and wanting to return to those better times. The Weight by The Band — Another old song, originally made public in 1968, but one I didnt hear until I was in high school more than 10 years later. I dont understand the words to the song pletely, but the feeling of the song is very forting to me. Under the Bridge by Red Hot Chili Peppers — This Los Angeles group wrote a song that I used to listen to when I first moved to LA more than 25 years ago. I didnt know anyone here when I first arrived. When I got bored, I used to drive up and down the major streets that cross the city from east to west, listening to this song about “the city of angels” being as “l(fā)onely as I am”. (Dont worry! I have plenty of friends now.) 語篇解讀：本文是一篇應(yīng)用文，主要介紹了在作者的手機(jī)音樂播放器中存的幾首歌曲的相關(guān)信息。 1．What does the underlined word “deep” probably mean? A．With skill. B．With fort. C．With a normal meaning. D．With a significant meaning. 解析：選D　詞義猜測題。根據(jù)第二段最后一句中的“Its a good ‘driving’ song, nothing plicated”可知，此處表示這首歌是一首說唱樂，適合駕車時聽，含義不復(fù)雜，故可推知這首歌沒有重大的意義，所以選D。 2．When did the author probably hear The Weight by The Band? A．In 1968.　　　　　　　　 B．In 1970. C．In the 1980s. D．In the 1990s. 解析：選C　細(xì)節(jié)理解題。根據(jù)第五段第一句“The Weight by The Band ... more than 10 years later”可知，這首歌于1968年發(fā)行，但是作者在十多年后才聽到，所以作者有可能是在20世紀(jì)80年代聽到這首歌的。 3．When the author first moved to LA, the song he used to listen to was ________. A．Say Something B．American Pie C．The Weight D．Under the Bridge 解析：選D　細(xì)節(jié)理解題。根據(jù)最后一段第一句可知，作者最開始到洛杉磯時經(jīng)常聽的一首歌是Under the Bridge。 B (2019昆明調(diào)研)When she was found off the coast of California four years ago, the fur seal, known as Ziggy Star, was skinny and fragile. She was unfit to return to the wild. And though a professional rescue team took her in to care for her, Ziggy continued to decline. “I wouldnt have given her next week，” says Uriarte, a surgeon who led a recent firstofitskind brain operation on the seal. The operation was the first of its kind to treat hydrocephalus in fur seals. The surgical team at Tufts was unable to find any documented evidence of a similar procedure, so they needed a lot of preparation to operate on Ziggys brain. The biggest concern in operating on Ziggy was how to control the animals anesthesia (麻醉). “When theyre under anesthesia their bodys reaction includes decreasing their heart rate, blood pressure, and breathing，” says Flower, who observes Ziggy and the other animals care, describing the special challenges of operating on seals. On the day of the surgery, Flower says that she and her team “were all quite anxious not knowing what would happen”. Moving quickly was extremely important; the longer she was under anesthesia, the more likely that she could lose her breathing, says the surgeon. The seal has been kept on land to prevent water from entering the cut on her head. Now, Ziggy is eating a full diet and is beginning to gain weight again. “Recently Ive allowed her to go swimming，” says Flower. However, the source of Ziggys neurological disorder (神經(jīng)紊亂) is still a mystery. “My theory is that when she was found, she had a head injury，” Uriarte says. “Hit by a boat maybe ... That happens a lot with seals.” Flower is less willing to guess. “I dont think theres enough information to make that assumption. We just dont know what happened to her.” 語篇解讀：本文是動物保護(hù)類記敘文。Ziggy Star是一只在加利福尼亞海岸被發(fā)現(xiàn)的非常瘦弱的海豹，因?yàn)閆iggy有腦積水，醫(yī)生為她進(jìn)行了手術(shù)，她現(xiàn)在已經(jīng)能夠正常進(jìn)食，體重也在逐步恢復(fù)，但究竟是什么導(dǎo)致了她的神經(jīng)紊亂，這依舊是一個謎。 4．When first found, Ziggy Star looked ________. A．thin and weak B．a(chǎn)ctive and excited C．bloody and fierce D．strong and energetic 解析：選A　細(xì)節(jié)理解題。根據(jù)第一段第一句中的skinny(極瘦的)和fragile(虛弱的)可知，A項(xiàng)正確。 5．What was the most challenging task on the day of the operation? A．Helping the seal regain her breathing. B．Using anesthesia properly on the seal. C．Making full preparations for the operation. D．Balancing the functions of the seals organs. 解析：選B　細(xì)節(jié)理解題。根據(jù)第二段中的“The biggest concern in operating on Ziggy was how to control the animals anesthesia (麻醉)”，由此可知，手術(shù)最大的挑戰(zhàn)是如何控制麻醉，所以選B。 6．What can we learn about Ziggy after the operation? A．She is strong enough to live in the wild. B．She is suffering from a heart rate disorder. C．She has already bee as heavy as before. D．She is recovering from the brain operation. 解析：選D　推理判斷題。根據(jù)文章最后一段第一句“Now, Ziggy is eating a full diet and is beginning to gain weight again”，由此可知，手術(shù)后，海豹已經(jīng)能夠正常進(jìn)食，體重也在恢復(fù)，所以選D。 7．What is probably the authors purpose in writing the text? A．To show humans love for a creature. B．To find out a way to operate on a seal. C．To remember an injured seal in danger. D．To explore the reasons for a seals injury. 解析：選A　目的意圖題。作者在文章中介紹了拯救受傷海豹的過程，旨在說明人們對于動物的愛護(hù)，所以選A。 C (2019名校原創(chuàng)預(yù)測卷二)Even before we were born, we knew our mothers voice and could distinguish it from other voices. Thats one of the key findings of an ongoing research project by Canadian and Chinese researchers. The research suggests that while we are still in the womb (子宮), our brains are learning speech patterns and laying the groundwork for language acquisition. “Before birth, the brain is being set up to learn language，” says Barbara Kisilevsky, who conducted the research. It had already been known that newborn babies show a preference for their mothers voice, but her latest research shows they also prefer that familiar sound while still in the womb. Kisilevsky carried out the first leg of the research in China, because she already had a research project under way there and this fit nicely with that work. Working with researchers at Zhejiang University, Kisilevsky tested 60 women in the final stage of pregnancy. All the mothers were taperecorded as they read a poem out loud. Then the mothers were divided into two groups. Half the fetuses (胎兒) heard the recording of their own mother. The other half heard that of another mother, but not their own. In both cases, the poem caused a change in the babys heart rate. The heart rate accelerated among those who heard their own mothers voice, and decelerated among those who heard a voice other than that of their mothers. Deceleration of the heart rate is “an attention mechanism (機(jī)制)”， Kisilevsky says. The heartbeat among fetuses who heard an unfamiliar voice slowed down, she says, because they were paying close attention to a voice they did not recognize. The fact that the heartbeat changed in both cases — up for Mom, down for someone else — shows the fetuses “noticed both voices”， she says, and could tell one from the other. By the way, the poem is immaterial here. Kisilevsky suspects she would have had the same results if the mothers had been reading a phone book. “Its not the content that the fetuses recognized，” she says. “We all have our own way of talking. We stop at different times, take breaths at different times, and thats what they are recognizing.” 語篇解讀：本文是一篇說明文，主要介紹了一項(xiàng)有關(guān)胎兒對聲音的識別的研究。 8．What did Kisilevskys research find? A．Babies are good language learners. B．Babies language acquisition begins after birth. C．Babies can recognize Moms voice while in the womb. D．Infants are more sensitive to Moms voice than fetuses. 解析：選C　細(xì)節(jié)理解題。根據(jù)第一段中的“Even before we were born, we knew our mothers voice and could distinguish it from other voices”并結(jié)合下文內(nèi)容可知，我們在出生之前就已經(jīng)熟悉母親的聲音，并能將其與其他聲音區(qū)分開來。由此可知，嬰兒在母親的子宮中就能識別母親的聲音。故選C。 9．What led to the change in fetuses heart rate according to the research? A．Their familiarity with the voice. B．The quality of the recordings. C．Their curiosity about everything. D．The content of the poem recorded. 解析：選A　細(xì)節(jié)理解題。根據(jù)倒數(shù)第二段中的“The heartbeat among fetuses who heard an unfamiliar voice slowed down, she says, because they were paying close attention to a voice they did not recognize”可知，胎兒在聽到不熟悉的聲音時，他們的心跳會減慢，因?yàn)樗麄儼迅嗟淖⒁饬Ψ旁诹怂麄儾荒茏R別的這個聲音上。由此可知，在研究中，胎兒對聲音的熟悉度的不同導(dǎo)致了他們心率的變化。故選A。 10．What can be inferred from the last paragraph? A．Adults talk in a way quite different from babies. B．Kisilevsky firmly believes her findings are applicable. C．Speech patterns are what fetuses recognize in telling voices. D．Different experimental materials can lead to different results. 解析：選C　推理判斷題。根據(jù)最后一段的內(nèi)容，尤其是“We all have our own way of talking. We stop at different times, take breaths at different times, and thats what they are recognizing”可知，胎兒在辨別聲音時識別的是人們的說話方式，即他們的語言模式。故選C。 11．In which column of a newspaper can we read this passage? A．Medicine. B．Lifestyle. C．Education. D．Science. 解析：選D　文章出處題。通讀全文可知，本文主要介紹了一項(xiàng)有關(guān)胎兒對聲音的識別的研究，它最可能出現(xiàn)在報紙的科學(xué)專欄上。故選D。 D (2019名校原創(chuàng)預(yù)測卷一)As the Earth warms from the increase of carbon dioxide in its atmosphere, the oceans that cover 70 percent of its surface are warming too. This warming will likely benefit some sea species at the expense of others. A study in the May 20 issue of the journal Nature confirmed that there has been a warming trend in the worlds oceans since 1993, as the waters have absorbed much of the extra energy in the planets atmosphere. The warming that has already occurred, and is expected to continue in the ing decades, will likely spell bad news for many ocean species, such as corals and species that live in the cold waters of the planets poles. But some creatures beneath the ocean surface might actually have an advantage in the newly warmed waters. A 2008 study, for example, said that a warming of just a few degrees Fahrenheit in Antarctic waters could make them suitable for sharks, which havent lived in the area for about 40 million years. Its easier for sharks to keep their high metabolism (新陳代謝) in warmer waters. If sharks do move into the area, they could cause damage to the existing ecosystems of the oceans around Antarctica. A study of starfish (海星) found these typical ocean creatures grew faster in waters at warmer temperatures and higher carbon dioxide levels (another result of all the extra greenhouse gas in the atmosphere) than in normal conditions — which is bad news for the shellfish they live on. Work by Jeremy Jackson, a professor at the Scripps Institution of Oceanography of the University of California San Diego, suggests that ocean warming — along with other threats such as overfishing and habitat (棲息地) destruction — could change once plex ocean ecosystems into ones that favor simpler species, such as microbes, toxic algal blooms and jellyfish. 語篇解讀：本文是一篇議論文。全球變暖會改變海洋生物的生存環(huán)境，影響海洋生態(tài)系統(tǒng)，但有些海洋生物卻能從中獲益。 12．How is Paragraph 3 mainly developed? A．By giving examples. B．By analyzing causes. C．By making parisons. D．By making classifications. 解析：選C　寫作手法題。根據(jù)第三段的內(nèi)容，尤其是“But”的轉(zhuǎn)折可知，本段主要是通過對比海洋變暖對哪些生物有利，對哪些生物有害來行文的。故選C。 13．What can we know about sharks from the fourth paragraph? A．They are native to Antarctic waters. B．They do harm to the whole ecosystem. C．They can benefit from warm water conditions. D．They threaten simpler species in Antarctic waters. 解析：選C　細(xì)節(jié)理解題。根據(jù)第四段中的“a warming ... make them suitable for sharks”“Its easier for sharks to keep their high metabolism (新陳代謝) in warmer waters”可知，鯊魚能夠從溫暖的水環(huán)境中獲益。故選C。 14．What will ocean warming likely bring about? A．Promoting the growth of starfish. B．An ecosystem of smaller creatures. C．Different food sources for sea creatures. D．Damaging living places of deepsea species. 解析：選A　細(xì)節(jié)理解題。根據(jù)第五段中的“A study of starfish (海星) found these typical ocean creatures grew faster in waters at warmer temperatures ... than in normal conditions”可知，海星在水溫比較高的水域會生長得更快，即海洋變暖會促進(jìn)海星的生長，故選A。 15．What is the purpose of the passage? A．To explain why ocean warming benefits some species. B．To introduce how creatures survive in warmer oceans. C．To clarify some misunderstandings about ocean warming. D．To show which sea species will benefit from warmer oceans. 解析：選D　寫作意圖題?？v觀全文，尤其是根據(jù)第一段中的“This warming will likely benefit some sea species at the expense of others”，第四段中的“make them suitable for sharks”和第五段中的“these typical ocean creatures grew faster in waters at warmer temperatures”可知，作者寫作本文主要是為了告訴我們哪些海洋物種能在海洋變暖中繼續(xù)繁衍，即從中獲益。故選D。 Ⅱ.閱讀七選五 (2019名校原創(chuàng)預(yù)測卷三)School is childrens base, where they learn to succeed.But for many children, the first day of school is filled with anxiety and fear.You might worry that you dont know anyone or that you wont fit in.__16__ However, preparing for the first day in advance will allow you feel more at ease and in control.
