2022年考博英语-中国农业科学院考前模拟强化练习题（附答案详解）1. 单选题The brunt of the attacks upon this commander was borne by his younger brother. Scarcely had the smoke been cleared from the battlegrounds of Nanking when voices arose maligning the younger governor who had erred in reporting to the throne the death of his successor.问题1选项A.backbitingB.gossiping aboutC.spreading rumorsD.slandering【答案】C【解析】考查动词词义辨析A选项backbiting“诽谤；中伤”；B选项gossiping about“闲聊……”；C选项spreading rumors“散布谣言”；D选项slandering“诽谤”；根据题目中的“voices arose”可知这个声音就是指的后面的内容，malign本意指的是“诽谤某人”，而在此处，题中的意思是“所出现的关于州长的谣言”。

所以答案为C“传播谣言”句意：非难指挥官的后果由他的弟弟承担了诽谤年轻的州长在向君王报告他的继承人的死讯时犯错了的谣言一出现时，南京战场的硝烟便难以消散了因此C选项正确2. 单选题Modern printing equipment quickly turns out duplicate copies of textual and pictorial matter.问题1选项A.identicalB.doubleC.illustratedD.legible【答案】A【解析】考查形容词辨析duplicate表示“复制的”A项identical“同一的，完全相同的”，B项double“双倍的”，C项illustrated“有插图的”，D项legible“清晰的，易辨认的”句意：现代印刷设备能迅速生产出文字和图片的复制品根据句意，该题选A正确3. 单选题The apartment was（ ）as $50,000 and its owner decided to sell it.问题1选项A.automatedB.assessedC.assertedD.avenged【答案】B【解析】考查动词辨析。

Alternatively, the cells could be frozen, providing a personalized tissue bank for use later in life.The new cells are adding credence to an emerging consensus among experts that the popular distinction between embryonic and “adult” stem cells-those isolated from adult bone marrow and other organs-is artificial.Increasingly, it appears there is a continuum of stem cell types, ranging from the embryonic ones that can morph into virtually any kind of tissue but are difficult to tame, up to adult ones that can turn into a limited number of tissues but are relatively easy to control.The newly analyzed fetal stem cells, scientists said, have many of the advantages of both.“They grow fast, as fast as embryonic stem cells, and they show great pluripotentiality,” meaning they can become many kinds of tissues, said study leader Anthony Atala, director of the Institute for Regenerative Medicine at Wake Forest University School of Medicine in Winston-Salem, N.C. “But they remain stable for years without forming tumors,” he added, something that embryonic cells are not very good at.Atala and other scientists emphasized that they don’t believe the cells will make embryonic stem cells irrelevant.“There’s not going to be one shoe that fits all,” said Robert Lanza, scientific director at Advanced Cell Technology in Worcester, Mass. “We’re going to have to see which ones are most useful for which clinical conditions.”George Daley, a Harvard stem cell researcher, echoed that sentiment. “They are not a replacement for embryonic stem cells,” he said.But in the past, even hints that non-embryonic cells might have medical potential similar to embryonic ones have complicated the political push to expand federal funding for the controversial field. And accordingly, opponents quickly pounced on the new results.65.（ ）is not a trait of embryonic stem cells.66. The cells that are shed by the developing fetus are（ ）.67.
