6：二、阅读理解：阅读下面的对话，选择合适的内容将对话补充完整。 （教材对话原文） Michael: They are testing the3D printer. Don’t you come and see it Lucas: What Never heard of it. Michael:It is one of the most latest technologicalinnovations. Lucas: Really{A; B; C;D; E}. Michael: Come on! You should learn to beopen-minded. Lucas: {A; B; C; D;E} Michael: The 3D printing technology could be used in construction,engineering, biomedicine, and many other fields. It can print anything, ahouse, a car, even a liver! Lucas: That can’t be true. I will never believethis. Michael:{A; B; C; D; E}.All thesewill be absolutely carried out by 3Dprinters. There’s a company called Natural Machines has introduced a 3D printerfor food producing. Lucas: I guess that there are a lot of procedures involvedin this process. So this printer must be very big. Michael:{A; B; C; D; E}. Itcan print all kinds of dessert and starter. Lucas: Is it expensive Michael:{A;B; C; D; E}. A. It is about $.1,000 B.Maybe its functions are questionable C. It is really true. D. What are the mainfunctions of it E. In fact, it is as big as an oven
10：二、阅读理解：阅读下面的短文，根据文章内容进行判断，正确为“T”，错误为“F”。 PASSAGE 1(教材课文原文) “The printer did notalways manage to spread the plastic evenly, making some of the ribs of thehoneycomb structure of the block uneven,” reported ARN(Australian RadioNetwork)to the surprise of no one who has used a 3D printer. But the architectsremain optimistic. The first few printed blocks are meant to be test pieces asthey improve the process. It takes about a week to print a 3-meter high blockright now. The project’s leaders hope to eventually get that down to two hoursand finish the first of 12 rooms in a year, and the entire house in less than 3years. Ultimately, 3D Print Canal House is an architectural research project,one that is very much being conducted in the public eye: you can actually buytickets to visit the construction site for 2.50 Euros. The top floors willbecome more ornate, for example, as newer techniques are incorporated. They’llexplore the possibilities of 3D printing, like the honeycomb walls or an entireroom recycled, redesigned, and built anew. Nobody’s going to move into a 3Dprinted house soon, but, if anyone ever does, something might be learned fromthis experiment by the canal. 1. According to the passage, the 3D printer cantype with plastic evenly.{T; F} 2. This 3D printerprinted some blocks totestitswork.{T; F} 3. The project’s leaders will finishthe entire house in less than 3years.{T; F} 4. 3D Print Canal House is printed to live.{T; F} 5. The canalhouse will be decorated more.{T; F}
12：二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。 （课外资料） In the grass, ababyduck washatched (孵化)out in a collegebiology lab with a backward left foot. At the time, itprobablywouldn’t have survived,ifMike Garydidn’t recommend a proper operation to cutoff that bad foot. Months after the healing process, engineers at NovacopyCompany produced a 3D printedmodelthat would be used to create a prosthetic(修复的)foot forthe duck. Consideringthat ABS plastics werenot flexible enough for this type of exercise, theNovacopy company made a three-dimensionally modeled foot made of silicone,withthe hope to create a permanentprosthesis(假肢)for the duck. It took just 13hours to produce. This 3D prosthesis demonstrated the 3Dtechnologies canbe usednot only for human application, but also in foreign subjects such as animalsand other medical treatments. 1. Wherewas the baby duck hatched out{A; B; C} A. In acollegebiology lab. B. In a backyard. C. In Noacopy Company. 2. Whatwas wrong with the babyduck{A; B; C} A. Itdidn’t survived. B. It was born with a backward left foot. C. Mike Garycut offthat bad foot. 3.Could ABS plastics be used toproduce a 3D printedmodelthatwould be used to create a prostheticfoot forthe duck{A; B; C} A. No, becauseABS plastics werenot flexible enough. B. Yes, but it could only be produced byNovacopy Company. C. Yes, because it was made of silicone. 4. How long did ittake to create a permanentprosthesis for the duck{A; B; C} A. 10 hours. B. 13hours. C. 30 hours. 5. What did the last sentence of this passage indicate{A;B; C} A.3Dtechnologies canbe used only for human application. B. 3Dtechnologiescanbe used only forforeigners. C. 3D technologiescanbe国开答案请进：opzy.net或请联系微信：1095258436 used tohuman, animalsand other medical treatments.
