【正文】 古生物學家) Alfred Romer a century ago became a hot topic once again.”和第四段中的“Homer thought that tidal (潮汐的) pools might have led to fish gaining limbs.”可知，是Alfred Romer最先提出了魚類可能因為潮汐而發(fā)展出四肢的理論。故選A。(2)考查細節(jié)理解。根據第七段中的“…tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.”過去的潮汐比現(xiàn)在強。這是因為地球這顆行星以前比現(xiàn)在離月球近了10%?？芍?，選B。(3)考查詞義猜測。根據第四段中的“Sea animals would have been forced into these pools by strong tides. ”可知，Homer認為海洋生物因為潮汐被迫進入水池；第八段中的“The creatures stranded in the pools would have been under the pressure of ‘’survival of the fittest, explained Mattias Green,“ 結合兩處可知，魚兒是被迫進入池中，故選D。(4)考查主旨大意。縱觀全文可知，英國生物學家達爾文的《物種起源》極大地提高了科學家對自然的認識。但仍有不少沒有根據的猜測。其中的一個猜測就是為什么在4億年前，海洋中的動物有了四肢，從而讓他們遷徙到陸地上生活。一個世紀以前，美國古生物學家Alfred Romer提出的一個想法，即潮汐可能導致魚類發(fā)展出四肢，這再次成為一個熱門話題。針對此許多科學家進行的實驗提供了許多新的證據來證實它。故選C?！军c評】本題考點涉及細節(jié)理解，詞義猜測和主旨大意三個題型的考查，是一篇科技類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。7．閱讀理解 Amazing concept images have shown what homes of the future could look like, as preparations are made for the world39。s first free from 3Dprinted property (房產). Experts will build a house called Curve Appeal, which will be 3Dprinted offsite before being put together onsite to create two outside walls, a roof and an inside part. These four main sections will then be joined together. Although 3Dprinted buildings have been made before, this home to be constructed in Chattanooga, Tennessee, later this year — will be the first of its kind, as it will contain no regular shapes or angles. The house is the creation of the design pany WATG, based in London and California. The design for Curve Appeal draws inspiration from the Case Study House program. The architects leading the program were famed for constantly pushing the limits in terms of minimalist (極簡主義) materials, and trying to create openplan spaces that focused on enhancing (增強) natural light. In a written statement, a spokesman for WATG said, “Employing many of the same modem design principles, Curve Appeal is the next evolutionary step. It39。s important that the architecture and the environment work together harmoniously. The chosen site is steps away from the Tennessee River in a beautiful wooded, sunlit area.” WATG was awarded the first prize in the Freeform Home Design Challenge in 2016 and given prize money of $ 8,000 to make its plans a reality. The petition was aimed at architects, designers, engineers and artists. Participants were challenged to design a 600 to 800sq ft singlefamily home that rethinks traditional aesthetics (美學), ergonomics, construction, building systems and structure. Over the last year, WATG39。s Chicago office has been developing their design with Branch Technology. This project is currently underway, working towards breaking ground later this year. Once pleted, the Curve Appeal home will have open and lightfilled inside living spaces.（1）From the passage we can know that Curve Apple . A.will be different from an ordinary houseB.is the first 3Dprinted buildingC.has apparent walls and a roofD.was ever built in the world（2）Where is the architect located according to Paragraph 4? A.Far away from the Tennessee River.B.In the woods near the Tennessee River.C.Between the Tennessee River and the woods.D.Next to some modem architectures.（3）What does the Freeform Home Design Challenge do? A.It motivates participants to design at random.B.It emphasizes traditions rather than modernization.C.It sponsors petitors when necessary.D.It helps put creative ideas into practice.（4）What39。s the passage mainly about? A.What our homes will look like in the future.B.The Freeform Home Design Challenge.C.The world39。s first freeform 3Dprinted house.D.The development of 3D in architecture.【答案】（1）A（2）B（3）D（4）C 【解析】【分析】本文是一篇說明文，介紹了世界上第一個免費的3D打印房子。(1)考查推理判斷。根據第二段中的“Experts will build a house called Curve Appeal, which will be 3Dprinted offsite before being put together onsite to create two outside walls, a roof and an inside part. These four main sections will then be joined together.”可知，Curve Apple不同于一般的房子。故選A。(2)考查細節(jié)理解。根據第四段中的“The chosen site is steps away from the Tennessee River in a beautiful wooded, sunlit area.”可知，建筑師住在the Tennessee River附近的樹林里。故選B。(3)考查推理判斷。根據倒數(shù)第二段中的“WATG was awarded the first prize in the Freeform Home Design Challenge in 2016 and given prize money of $ 8,000 to make its plans a reality. The petition was aimed at architects, designers, engineers and artists.”可知，the Freeform Home Design Challenge有助于把創(chuàng)造性的想法付諸實踐。故選D。(4)考查主旨大意。根據第三段中的“Although 3Dprinted buildings have been made before, this home to be constructed in Chattanooga, Tennessee, later this year — will be the first of its kind, as it will contain no regular shapes or angles.”可知，本文主要談論的是世界上第一個免費的3D打印房子。故選C?！军c評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科普類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。8．閱讀理解 We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(濕度)and nutrient availability seem to have trumped the benefits of increased carbon dioxide said researchers from the National University of Singapore. 45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures. We do not yet know the mechanisms(機制)involved, or why some organism are getting smaller while others are unaffected, the researchers said. Until we understand more, we could be risking negative consequences that we can39。t yet quantify. The change is big in coldblooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行動物)smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陳代謝). Greater use of energy resulted in tiny tortoises and little lizards.
