It’s not every day that the United States history mixes with microbes (微生物) in the soil.But when the grassland on the National Mall in Washington,D.C.was replaced,it offered scientists the opportunity to study changes in the soil beneath.
The work focu
2、sed on the bacteria present in the soil.To the
researchers’ surprise,the communities of microbes did not change a lot before and after the replacement.These communities in the soil are known as the soil microbiome (微生物群).
“My lab is interested in how microbes can move around in the environment,an
3、d how they change and adapt as a result of this movement,” explains Jo Anne Crouch,the lead author of the study.“We thought that the new ‘imported’ turf (草皮) from New Jersey would introduce different communities of bacteria to the National Mall.However,we found that they weren’t significantly differ
4、ent.”
Crouch’s work focused on turf grass,defined as a large area of green grass.It is made up of the grass,its roots,and the soil and microbes found with them.
Think of the soil microbiome as similar to the collection of microbes found in the human body.When the microbes are out of balance,it can
5、 make someone sick.Crouch says it’s the same for the soil microbiome.Many of the worst diseases in crops or other environments are linked with changes in the soil microbiome.
Additionally,Crouch says that even though the changes between the soils were small,scientists are also starting to appreciat
6、e that sometimes a really important microbe is a rare one.This means it would be hard to observe but could greatly affect how the groups function as a whole.“Agricultural areas and other natural spaces are highly and easily hurt by negative changes,” she says.“Microbiomes offer an almost entirely ne

語(yǔ)篇解讀:正
11、如人體的微生物群落對(duì)人體的健康有影響一樣,土壤的微生物群落也會(huì)對(duì)植物的產(chǎn)量和健康產(chǎn)生影響。
答案及剖析:
1.C 細(xì)節(jié)理解題。根據(jù)第二段中的To the researchers’ surprise,the communities of microbes did not change a lot before and after the replacement.These communities in the soil are known as the soil microbiome.可知,令研究者驚訝的是土壤微生物群落幾乎保持穩(wěn)定。
2.D 細(xì)節(jié)理解題。根據(jù)第三段中的We thought
12、 that the new ‘imported’ turf from New Jersey would introduce different communities of bacteria to the National Mall.However,we found that they weren’t significantly different.可知,通過(guò)研究草皮,克勞奇和她的團(tuán)隊(duì)發(fā)現(xiàn)新移植過(guò)來(lái)的草皮帶來(lái)的微生物群落與原來(lái)的微生物群落類似。
3.A 推理判斷題。根據(jù)第五段第一句Think of the soil microbiome as similar to the collectio
13、n of microbes found in the human body.及該段后面的內(nèi)容可推知,作者提及人類體內(nèi)的微生物是為了表示這兩種類型的微生物扮演著類似的角色。
4.B 推理判斷題。最后一段提到微生物群落提供了一個(gè)提高莊稼產(chǎn)量、促進(jìn)植物健康的全新機(jī)會(huì)。由此可知,對(duì)微生物群落的研究對(duì)農(nóng)業(yè)是有益的。

3.B hard艱難的;later以后的;last最后的,上一個(gè);precious珍貴的。本文描述的是我的成長(zhǎng)經(jīng)歷,故in my later years(在以后的歲月里)符合語(yǔ)境,故選B。

7.C 句意:盡管這些非常不重要,但是我總會(huì)從工作中獲得自豪感和滿足感。根據(jù)句意可知,用although引導(dǎo)讓步狀語(yǔ)從句,故選C。
