Unit 20 New Frontiers 课时练1　2篇阅读＋1篇完形＋1篇应用文写作 Ⅰ.阅读理解 A ‎(2020·大连一模)Emilia Dobek traces her interest in space and the universe back to third grade when she and her father watched a blood moon—a total lunar eclipse(月食)—on the roof of their house.‎ Now a seventh grader at East Prairie Elementary School, Dobek recently won the national Discovery Education Lockheed Martin Beyond Challenge by designing a space station for travelling to Mars.‎ She says that night watching the lunar eclipse started a strong desire in her that has yet to run out of fuel. So when her teacher Andrea Smeeton received information about the national challenge, Smeeton said she immediately had one student in mind.‎ ‎“I knew she would love the challenge and that she would go way beyond in her search，” Smeeton said. “She immediately started researching bone density(密度) of astronauts and how to have food on Mars.”‎ ‎“My design will ensure the safety of the astronauts but also make sure their comfort is out of this world，” Dobek says.‎ Dobek’s design calls for building the MSS or Mars Storage Station to put the supplies in. It also includes the SGF or SelfGrowing Farm, and she details how it would work with the elements on Mars.‎ Then there is physical and leisure activity for the astronauts under Dobek’s design. A simulator(模拟装置) allows astronauts to choose their exercise machine and virtual reality environment. Rooms have circular ceilings so astronauts will be able to watch downloaded shows and even see places on Earth, such as their homes.‎ ‎“I want to tell other kids to follow their passions，” Dobek said. “Whatever they want to do, they should push for it and always try their best.”‎ ‎【解题导语】　本文主要介绍了小学生Emilia Dobek设计太空站，并赢得挑战的相关内容。‎ ‎1．Dobek first became interested in space when ________．‎ A．she was still a seventh grader 14‎ B．she studied at a junior high school C．she lived on the top of their house D．she watched an eclipse of the moon D　解析：细节理解题。根据第一段“Emilia Dobek traces her interest in space and the universe back to third grade when she and her father watched a blood moon—a total lunar eclipse(月食)—on the roof of their house.”可知，Dobek对太空感兴趣是从她三年级时的一个晚上观看一次月食开始的。‎ ‎2．Smeeton recommended that Dobek take the challenge because ________．‎ A．she knew Dobek liked challenges in life B．she had no other students interested in Mars C．Dobek knew how to research bone density of astronauts D．she was sure that Dobek would have outstanding performance D　解析：推理判断题。根据第四段Smeeton的话可推知，她对Dobek很了解，对其可以接受这项挑战并出色完成充满信心。‎ ‎3．What does Dobek focus on when designing the space station?‎ A．The environment on Mars.‎ B．The safety of the supplies.‎ C．The activities for astronauts.‎ D．The comfort of the astronauts.‎ D　解析：推理判断题。根据文章第五段中的“make sure their comfort is out of this world”并结合对倒数第二段的整体理解可推知，Dobek的设计包含身体和休闲活动，让宇航员在太空中也能感到舒适。‎ B ‎(2020·兰州高三诊断)A new chapter opened in mankind’s exploration of the moon on Thursday morning as the first probe(航天探测器) to land on the moon’s far side reached its destination after a 26day journey. The Chang’e 4 lunar probe, representing China’s latest step in lunar investigation, landed at 10：26 am at the Von Kármán crater and then sent back three photos of the landing site shot by cameras on the probe’s lander(着陆器), marking the world’s first images taken on the surface of the far side.‎ One of the photos, published by the China National Space Administration, shows the place where Chang’e 4’s rover, which was named Yutu 2 on Thursday night, will be heading to explore and survey. Thus began the first long journey to the side of the moon that faces away from the Earth. It is meant to fulfill scientists’ long 14‎ ‎held desire to closely observe the lesser known region.‎ Tidal(潮汐的)forces on Earth slow the moon’s rotation to the point that the same side always faces Earth. The other side, most of which is never visible from Earth, is the far side of the moon. While it has been photographed by spacecraft, starting with a Soviet probe in 1959, no probe had ever made a soft landing there, so scientists had not been able to conduct surfacelevel observations and surveys of the region.‎ Wu Weiren, chief designer of China’s lunar program, said in Beijing on Thursday that the landing “was perfect”. He called the event “an important milestone for China’s space exploration”， adding that it has made a good start for future lunar exploration efforts.‎ With its investigation of the far side, particularly the Von Kármán crater, the Chang’e 4 mission will enable scientists to find out what they haven’t known about the moon and deepen their knowledge of its early history and of the solar system.‎ ‎【解题导语】　嫦娥四号探测器在月球背面着陆，这标志着中国探月工程的巨大进步，同时也为人类了解月球的背面提供了信息。‎ ‎4．What is the first paragraph mainly about?‎ A．The basic data of the Chang’e 4 lunar probe.‎ B．The Chang’e 4’s worldfirst landing on the moon’s far side.‎ C．The Chang’e 4’s 26day visit to the far side of the moon.‎ D．The description of the photos taken on the surface of the moon’s far side.‎ B　解析：段落大意题。根据第一段第一句“A new chapter opened in mankind’s exploration of the moon on Thursday morning as the first probe(航天探测器) to land on the moon’s far side reached its destination after a 26day journey.”可知，本段主要介绍了嫦娥四号实现了人类首次在月球背面着陆。故选B。‎ ‎5．What does the underlined word “it” in the third paragraph refer to?‎ A．The lander.‎ B．The rover.‎ C．The far side of the moon.‎ D．The Chang’e 4 lunar probe.‎ C　解析：代词指代题。根据第三段的第二句“The other side, most of which is never visible from Earth, is the far side of the moon.”以及画线词所在句中的“While it has been photographed by spacecraft”可知，it在这里指代“the far side of the moon”，故选C。‎ 14‎ ‎6．What can we infer from this text?‎ A．It is only on the moon that people can explore the deep space.‎ B．The scientific information obtained by Chang’e 4 will be new to the world.‎ C．It is the first time for people to see the pictures of the far side of the moon.‎ D．Chinese space technology is more advanced than that of any other country’s.‎ B　解析：推理判断题。根据第一段最后一句中的“marking the world’s first images taken on the surface of the far side”可知，嫦娥四号月球探测器发回的照片是世界上首次在月球背面拍摄的，由此可推知，B项正确。‎ ‎7．In which section of a website can we probably read this text?‎ A．Tourism.‎ B．Health Care.‎ C．Science and Technology.‎ D．Art and Entertainment.‎ C　解析：文章出处题。本文为新闻报道，介绍了嫦娥四号探测器首次在月球背面着陆，这标志着中国探月工程的巨大进步，由此可推知，本文可能出自一个网站的科技版面。故选C。‎ Ⅱ.完形填空 ‎(2020·商丘高三模拟)Earlier that evening, my mother called, telling me that my brother died in a car crash.

Crows actually do understand how to make water displacement(排水量) work to their advantage, experiments show. The results suggest that the birds are, at least in some aspects, as smart as firstgraders.‎ Researchers, led by Sarah Jelbert at the University of Cambridge, presented six crows with tubes containing water. Inside the tubes, a worm or a piece of meat on a piece of wood was floating, just out of reach of the crows. In front of the tubes, the researchers arranged several rubber erasers that would sink, and some plastic objects that would float. The crows found out that they could drop the erasers into the tubes in order to raise the water level and get their snack.‎ However, the__birds__handled__awkwardly in experiments in which they could choose to drop objects in either a wide tube or a narrow one to get a snack, the 14‎ ‎ researchers said. Dropping objects into a narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops; while it took around seven drops to raise the snack to the same level in the wide tube. The crows obviously didn’t realize this, and most of them went for the wide tube first.‎ Previous studies showed that chimps and human children can solve similar tasks. In a 2011 study, chimps and kids found out that they could put water into a tube to reach a peanut that was floating in a small amount of water at the bottom.‎ ‎【解题导语】　本文主要介绍了科学家通过实验对乌鸦智商进行的研究。‎ ‎1．How did the crows get the snack in Sarah’s experiment?‎ A．By breaking the tube.‎ B．By dropping in erasers.‎ C．By standing on the wood.‎ D．By removing the wood.‎ B　解析：细节理解题。根据第三段最后一句“The crows found out that they could drop the erasers into the tubes in order to raise the water level and get their snack.”可知，乌鸦能够把橡皮擦扔到管里，使水位升高，然后吃到零食。所以选B项。‎ ‎2．What does the author mean by “the birds handled awkwardly” in Paragraph 4?‎ A．They were unable to tell different shapes.‎ B．They dropped objects only into narrow tubes.‎ C．They were not aware of the snack at first sight.‎ D．They mostly avoided the easier way to get the snack.‎ D　解析：推理判断题。从第四段可知，实验中的乌鸦在面对粗细不同的管子时，虽然只需往细管里投两次物体就可以够到零食，而需往粗管里投大约七次物体才能够到零食，但是乌鸦往往先去粗管那边，而没有选择更容易获得零食的细管。由此可推知，画线部分是说它们通常没有选择更容易的方式得到零食。‎ ‎3．What does the text mainly focus on?‎ A．Stories of Aesop’s Fables.‎ B．The development of crows.‎ C．Crows’ intelligence.‎ D．Humananimal communication.‎ C　解析：主旨大意题。根据第二段最后一句“The results suggest that the birds are, at least in some aspects, as smart as firstgraders.”以及下文中的实验可知，整篇文章都是围绕乌鸦的智商问题来展开的。‎ 14‎ ‎4．What do we know about crows in the passage?‎ A．Crows are almost as clever as firstgraders in some respects.‎ B．Crows understand water displacement completely.‎ C．Chimps and children are much smarter than crows.‎ D．The story of The Crow and the Pitcher lacks evidence.‎ A　解析：推理判断题。根据第二段最后一句“The results suggest that the birds are, at least in some aspects, as smart as firstgraders.”可知，乌鸦在一些方面几乎跟一年级学生一样聪明。‎ B ‎(2020·郑州第一次质量预测)If you’ve ever had a dog, you know just how deep a connection you can develop with “man’s best friend”. But a dog’s life is much shorter than humans, about 12 to 15 years long, which means every dog owner has to go through the heartbreaking moment when their loving pet passes away.‎ Why not make a clone of that dog then? This is the solution offered by a South Korean company, Sooam Biotech Research Foundation. The company has already successfully cloned at least 400 dogs, mostly for US customers, ever since it pioneered the technique in 2005. Now, Sooam Biotech has introduced its business to UK dog owners as well, offering them dogs that look just like their lost ones.‎ To clone a dog, researchers first need to take a skin cell from a living dog or one that has just died. Meanwhile, another dog is selected to supply an egg. Researchers then replace the DNA in the egg with that from the skin cell and implant the egg into the womb(子宫) of a female dog. The egg grows into a puppy over the following two months.‎ The whole process takes a very short time, but it comes at a shockingly high price—around ￡ 63，000. But if you can’t afford it now, you can also save the cell in a laboratory and access it at a later date.‎ However, magical as cloning might sound, there is no guarantee that the cloned dog will be a perfect copy of the original one. Just like identical twins of humans, they share the exactly same DNA but there will still be small differences between them. “The spots on a Dalmatian(斑点狗) clone will be different, for example，” Insung Hwang, head of Sooam Biotech, told The Guardian.‎ Dog owners will also have to accept the fact that personality is not “cloneable”. Apart from genes, personality is also determined by upbringing and 14‎ ‎ environment, which are both random elements that cloning technologies simply cannot overcome, Professor Tom Kirkwood at Newcastle University, UK, told The Telegraph.‎ Perhaps bringing our dogs back by cloning is not the best way to remember them after all. Kirkwood, a dog owner himself, pointed out, “An important aspect of our relationship with them is coming to terms with the pain of letting go.”‎ ‎【解题导语】　本文是一篇说明文，主要介绍了克隆狗技术。‎ ‎5．What service does Sooam Biotech Research Foundation offer?‎ A．Making copies of pet dogs.‎ B．Giving pet dogs identical twins.‎ C．Helping dogs give birth to more puppies.‎ D．Helping dog owners love their dogs more.‎ A　解析：细节理解题。根据第二段最后一句“Now, Sooam Biotech has introduced its business to UK dog owners as well, offering them dogs that look just like their lost ones.”可知，这家公司所提供的服务就是克隆已逝的宠物狗，故选A。‎ ‎6．Which order is correct in the dog cloning process?‎ a．An egg is taken from another dog.‎ b．A skin cell is taken from the pet dog.‎ c．The egg grows into a puppy in two months.‎ d．The egg is placed in the womb of a female dog.‎ e．The DNA in the egg is replaced by the DNA from the skin cell.‎ A．a→d→b→e→c.　　　　　 B．a→e→b→d→c.‎ C．b→a→d→e→c. D．b→a→e→d→c.‎ D　解析：细节理解题。根据对第三段的整体理解可知，实验的第一步是从狗身上提取皮肤细胞，另一只被选择的狗提供一个卵子，将卵子中的DNA替换成皮肤细胞中的DNA之后，将卵子植入一只母狗的子宫，最后卵子在接下来的两个月中生长为一只小狗，故选D。‎ ‎7．What can we learn about dog cloning from the passage?‎ A．It has not been put into practice until recently.‎ B．It is very popular among US and UK pet owners.‎ C．It might not give the owners an exactly same dog.‎ D．It is very expensive and usually takes half a year to complete.‎ C　解析：细节理解题。根据第五段第一句“However, magical as cloning might sound, there is no guarantee that the cloned dog will be a perfect copy of the original one.”可知，克隆狗和原来的狗可能并非完全一样，故选C。‎ ‎8．What does Kirkwood think of dog cloning?‎ 14‎ A．He disagrees with it.‎ B．He supports it.‎ C．He is curious about it.‎ D．He thinks it unbelievable.‎ A　解析：观点态度题。根据最后一段Kirkwood说的话“An important aspect of our relationship with them is coming to terms with the pain of letting go.”可知，他认为人类和宠物狗之间的关系的一个重要方面是要接受失去它们的痛苦。由此可推知，Kirkwood并不赞成克隆狗，故选A。‎ Ⅱ.七选五 ‎(2020·平顶山名校模拟)It is not as simple as opening the door and hitting the track in winter. There are a few things you can do to ensure you are getting the most out of your run and, importantly, not doing more harm than good.‎ Warm up, cool down ‎1．________. Your muscles need some time to warm up when it’s cold, so take it easy when you set off and do a few stretches once you’re finished.‎ Drink water You might not feel hot, but that’s because sweat evaporates(蒸发) more quickly into the chilly, dry air. So be sure to drink water before, during and after coldweather workouts. 2.________. A belt bottle conveniently attaches to your waist so you don’t have to carry it and can have a drink whenever you feel like it.‎ ‎3．________‎ Running in cotton is a bad idea. Wear thin, breathable layers of synthetic(合成的) clothing that help protect you from the wind and snow, but still let out heat and moisture. Thirty percent of your body heat escapes through your hands and forty percent through your head. Wear a hat, or beanie(无檐小便帽), and gloves so your circulatory system can distribute warm blood to the rest of your body. 4.________．‎ Run into the wind ‎5．________. Obviously, it will be an easier passage home with some extra help from Mother Nature.
