Ⅲ．阅读理解
A recent study published in the journal Nature has revealed that our Medieval ancestors left us with a biological legacy: Genes that may have helped them survive the Black Death make us more vulnerable to certain diseases today.
Barreiro and his colleagues examined ancient DNA samples from the bones of more than 200 people from London and Denmark who died over about 100 years that stretched before，during，and after the Black Death swept through that region.
They identified four genes that，depending on the variant，either protected against or increased vulnerability(易损性)to the bacteria that causes bubonic plague(腺鼠疫).They found that what helped people in Medieval times led to problems generations later — raising the frequency of mutations(突变) harmful in modern times.Some of the same genetic variants identified as protective against the plague are associated with certain autoimmune disorders，such as Crohn's disease.In these sorts of diseases，the immune system that defends the body against disease and infection attacks the body's own healthy tissues.
Past research has also sought to examine how the Black Death affected the human genome.But Barreiro said he believes theirs is the first demonstration that the Black Death was important to the evolution of the human immune system.One unique aspect of the study，he said，was to focus on a narrow time window around the event.It's extremely sophisticated and addresses important issues，such as how the same version of a gene can protect people from a horrific infection and also put modern people at risk for other illnesses.
All of this begs the question: Will the pandemic have a big impact on human evolution？Barreiro said he doesn't think so because the death rate is so much lower and the majority of people who have died had already had children.In the future，however，he said more deadly pandemics may well continue to shape us at the most basic level.“It's not going to stop.It's going to keep going for sure.”
【语篇解读】 本文是一篇说明文。文章主要介绍了我们的中世纪祖先给我们留下了一份生物遗产：可能帮助他们在黑死病中幸存下来的基因，使我们今天更容易受到某些疾病的影响。
1．How did Barreiro's team come up with the finding
A．By analyzing DNA samples from targeted bones.
B．By testing the vulnerability of four specific genes.
C．By identifying the frequency of harmful mutations.
D．By focusing on the consequences of autoimmune disorders.
√
A [细节理解题。根据第二段“Barreiro and his colleagues examined ancient DNA samples from the bones of more than 200 people from London and Denmark who died over about 100 years that stretched before，during，and after the Black Death swept through that region.(巴雷罗和他的同事们检查了来自伦敦和丹麦的200多人骨头上的古代DNA样本，这些人在黑死病席卷该地区之前、期间和之后去世了大约100年。)”可知，巴雷罗是通过分析目标骨骼的DNA样本得出这一结论的。故选A。]
2．What does Barreiro believe make their research distinct from previous research
A．It is the first to show a variant of gene can lead to infection.
B．It illustrates how gene variants can make us free of immune disorders.
C．It focuses on an extensive time window around the Black Death event.
D．It is the first to confirm the plague is responsible for certain immune disorders.
√
D [细节理解题。根据第四段中“But Barreiro said he believes theirs is the first demonstration that the Black Death was important to the evolution of the human immune system.(但巴雷罗说，他认为他们的研究首次证明了黑死病对人类免疫系统的进化很重要)”可知，这是第一次证实鼠疫是导致某些免疫系统紊乱的原因。故选D。]
3．Which of the following statements will Barreiro probably agree with
A．There will be more pandemics causing death to people.
B．Pandemic will continue to impact human evolution.
C．New pandemics may still influence how human immune system develops.
D．Modern people are protected from deadly pandemics due to the same gene.
√
C [细节理解题。根据最后一段中“In the future，however，he said more deadly pandemics may well continue to shape us at the most basic level.(然而，他说，在未来，更致命的流行病很可能继续在最基本的层面上塑造我们。)”可知，新的流行病仍可能影响人类免疫系统的发展。故选C。]
4．What is a suitable title for the text
A．Genetic variants: They make us victims of the Black Death
B．Genetic twist: Medieval plague may have shaped our immunity
C．Time window: The factor plays an important role in a recent study
D．Deadly pandemics: They will keep changing our immune system for sure
√
B [标题归纳题。根据第一段“A recent study published in the journal Nature has revealed that our Medieval ancestors left us with a biological legacy: Genes that may have helped them survive the Black Death make us more vulnerable to certain diseases today.(最近发表在《自然》杂志上的一项研究揭示，我们的中世纪祖先给我们留下了一份生物遗产：可能帮助他们在黑死病中幸存下来的基因，使我们今天更容易受到某些疾病的影响。)”可知，本文主要介绍了中世纪祖先在黑死病中幸存下来的基因，使我们今天更容易受到某些疾病的影响。故选B。]

Ⅲ.阅读理解
A recent study published in the journal Nature has revealed that our Medieval ancestors left us with a biological legacy: Genes that may have helped them survive the Black Death make us more vulnerable to certain diseases today.
Barreiro and his colleagues examined ancient DNA samples from the bones of more than 200 people from London and Denmark who died over about 100 years that stretched before，during，and after the Black Death swept through that region.
They identified four genes that，depending on the variant，either protected against or increased vulnerability(易损性)to the bacteria that causes bubonic plague(腺鼠疫).They found that what helped people in Medieval times led to problems generations later — raising the frequency of mutations(突变) harmful in modern times.Some of the same genetic variants identified as protective against the plague are associated with certain autoimmune disorders，such as Crohn's disease.In these sorts of diseases，the immune system that defends the body against disease and infection attacks the body's own healthy tissues.
Past research has also sought to examine how the Black Death affected the human genome.But Barreiro said he believes theirs is the first demonstration that the Black Death was important to the evolution of the human immune system.One unique aspect of the study，he said，was to focus on a narrow time window around the event.It's extremely sophisticated and addresses important issues，such as how the same version of a gene can protect people from a horrific infection and also put modern people at risk for other illnesses.
All of this begs the question: Will the pandemic have a big impact on human evolution？Barreiro said he doesn't think so because the death rate is so much lower and the majority of people who have died had already had children.In the future，however，he said more deadly pandemics may well continue to shape us at the most basic level.“It's not going to stop.It's going to keep going for sure.”
1．How did Barreiro's team come up with the finding
A．By analyzing DNA samples from targeted bones.
B．By testing the vulnerability of four specific genes.
C．By identifying the frequency of harmful mutations.
D．By focusing on the consequences of autoimmune disorders.
2．What does Barreiro believe make their research distinct from previous research
A．It is the first to show a variant of gene can lead to infection.
B．It illustrates how gene variants can make us free of immune disorders.
C．It focuses on an extensive time window around the Black Death event.
D．It is the first to confirm the plague is responsible for certain immune disorders.
3．Which of the following statements will Barreiro probably agree with
A．There will be more pandemics causing death to people.
B．Pandemic will continue to impact human evolution.
C．New pandemics may still influence how human immune system develops.
D．Modern people are protected from deadly pandemics due to the same gene.
4．What is a suitable title for the text
A．Genetic variants: They make us victims of the Black Death
B．Genetic twist: Medieval plague may have shaped our immunity
C．Time window: The factor plays an important role in a recent study
D．Deadly pandemics: They will keep changing our immune system for sure
