What’s a man? Or, indeed, a woman? Biologically, the answer might seem obvious. A human being is a(n) 【C1】______who has grown from a fertilised egg which【C2】______genes from both father and mother. A growing band of biologists, 【C3】______, think this definition incomplete. They【C4】______people not just as individuals, but also as ecosystems. In their view, the descendant of the fertilised egg is【C5】______one component of the system. The others are trillions of bacteria, each equally an individual, 【C6】______are found in a person’ s gut, his mouth, his skin and all of the crevices and orifices that exist in his body’s surface.
A【C7】______adult human harbours some 100 trillion bacteria in his gut alone. That is ten times as many bacterial cells as he has cells【C8】______from the sperm and egg of his parents. These bugs, moreover, are【C9】______. Egg and sperm provide about 23, 000 different genes. The microbiome, as the body’s commensal bacteria are collectively known, is reckoned to have around 3million.【C10】______, many of those millions are variations on common themes, but equally many are not, and even the number of【C11】______that are adds something to the body’ s genetic mix.
And it really is a system, for evolution has【C12】______the interests of host and bugs. In exchange for raw materials and shelter the microbes that live in and【C13】______people feed and protect their hosts, and are thus integral to that host’s well-being. Neither wishes the other harm. In bad【C14】______, though, this alignment of interest can【C15】______. Then, the microbiome may misbehave in ways which cause disease.
That bacteria can cause disease is no【C16】______. But the diseases in question are. Often, they are not acute infections of the【C17】____ 20th-century medicine has been so good at dealing with. They are, rather, the chronic illnesses that are now, 【C18】______in the rich world, the main focus of medical attention.【C19】______, from obesity and diabetes, via heart disease and asthma to neurological conditions such as autism, the microbiome seems to play a(n) 【C20】______role.
【C8】
选项
A、derived
B、drawn
C、descended
D、acquired
答案
C
解析
本题考查动词辨析。此处…he has ceils______from the sperm and egg of his parents意为“这一数字是他从父母的精子与卵子中获得的细胞数量的十倍”。四个选项均能与from搭配。构成过去分词短语作定语,修饰cells。但descend from“由……留传下来”,符合题意,故C.descended为正确答案。derive from“起源于”,draw from“从……中提取”,acquire from“获取”,均不符合题意,故排除。
