1、Module 5 Great People and Great Inventions of Ancient China“阅读七选五完形”组合练练题型(限时：35分钟).阅读理解(2020兰州高三诊断)Threedimensional printers are fast becoming everyday devices in the United States. ThreeD printers are used to make everything from automobile parts to bone replacements for human patients. American r
2、esearch scientists are now working on creating replacements for living tissue.Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2020. This process is called biofabrication (生物制造). It requires special printing equipment and a s
3、pecial kind of ink.Traditional printers require ink to produce an image or design on a piece of paper. For their threeD printer, the South Carolina researchers prepare complex nutritious solutions they call bioinks. Bioinks are made of proteins and glucose (葡萄糖), which normally provides energy for m
4、ost cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bioinks are then added to a device that researchers call the Palmetto bioprinter.Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina.
5、 She says new technology, like the Palmetto bioprinter, is a great help to the biofabrication process.The bioinks are placed in three dispensers (分配器), containers, inside the printer. Lasers control both the position of the printing surface and the places where the bioink is released.Michael Yost is
6、 a leader of the research team. He says the printing process is fully automated machineoperated. He says that the Palmetto bioprinter makes it possible to create complex tissue types.The researchers say bioprinting is still experimental. But they hope in a few years they may be able to print tissue
7、to replace damaged human organs.But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive.Michael Yost hopes that more people will believe in the benefits of biofa
8、brication.“Tissue biofabrication is a reality, and it is a reality now, and if you come here and you get to see it. You will get to see it. You cant touch it, but you will see it and think this is real. And this is really human.”语篇解读：本文是一篇说明文。从汽车配件到人体骨骼，3D打印技术在美国已经得到了广泛的应用。现在科学家们正致力于3D打印人体组织的生物制造研究。
9、1What can we know about the bioinks?AThey are the necessities of bioprinting.BThey only contain proteins and glucose.CThey can be placed in the traditional printers.DThey are available in our local drugstores.解析：选A推理判断题。根据第三段前两句可知，生物墨水对于人体组织3D打印机而言就如同墨对于传统打印机。由此可知，它们对于生物打印来说不可或缺。故选A。2Which of the fo
10、llowing is one of the concerns with biofabrication?AResearchers cant find enough living cells of animals to make the bioinks.BThe price of the bioprinter is too high and most people cant afford it.CScientists have some difficulty in getting the blood to the replacement tissue.DPeople are worried abo
11、ut the safety of the biofabrication process.解析：选C细节理解题。根据倒数第三段第二句可知，如何将血液输入打印好的组织中是科学家们要解决的问题之一。故选C。3According to Michael Yost, we can infer that _.Athe Palmetto bioprinter can work without powerBthe Palmetto bioprinter has been used to treat the patientsCthe Palmetto bioprinter can only be found in
12、 the United StatesDthe Palmetto bioprinter will have a bright future in medical use解析：选D推理判断题。根据第六段最后一句“He says that the Palmetto bioprinter makes it possible to create complex tissue types.”及第七段内容可知，将来可以用3D打印的人体组织来取代损坏的人体器官。故选D。4The passage mainly tells us about _.Athe threeD printer and its workin
13、g principlesBthe bioinks and their use in bioprintingCthe spread use of the bioprinter in the USADthe growing demand for biofabrication解析：选B主旨大意题。本文是一篇说明文，第一段最后一句是文章的中心句，由此结合下文内容可知，本文主要介绍的是3D人体组织打印技术方面的研究的进展情况。故选B。.阅读七选五(2020江西八所重点中学联考)We all face quantities of stress in a daytoday living, whether a
