21、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 COVID-19 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．COVID-19 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
22、Have you ever taken photos by using mobile phones with selfie sticks(自拍杆)? This new invention is a small, useful and cleverly－designed tool.
However, a pair of US artists from New Mexico, Arie Snee and Justin Crowe believe they have invented a better one and they call it “selfie arm”. For better or worse, they have taken the world by storm. It makes those people in the pictures seem to be holding hands with a loved one．
The pair say it offers a far better experience than using a straight stick. The selfie arm makes people feel they are not alone when they take photos. It seems that they are together with their friends. They think their invention solves the main problem that the selfie stick has — people look alone while they are taking pictures of themselves with great interests. The product, at present, just an art project and a model, conveniently provides you a welcoming arm. And better yet in the future, it'll talk in a friendly way and never get angry or upset. The pair say they are fascinated by these new ideas.
The “selfie arm” is made of fiberglass(玻璃纤维). It is lightweight and easytaking.
The project that they work on shows the growing selfie stick phenomenon(现象) directly and the increasing need for narcissism(自恋) and Internet agreement.
【1】The selfie arm is ________．
A．the latest mobile phone
B．lightweight and easy-taking
C．cleverlydesigned but useless
D．a useful digital camera
【2】“The pair say it offers a far better experience than using a straight stick.” Here “it” refers to ________.
A．a selfie stick
B．a selfie arm
C．a hand
D．a loved one
【3】________will make people feel they are alone while taking photos．
A．The storm
B．The selfie arm
C．The pair
D．The selfie stick
【4】The passage is mainly talking about ________.
A．a new kind of fiberglass

23、 You’ve probably heard of Marco Polo, but how much do you actually know about him and his incredible journey? Marco was the original travel writer, whose trade contacts with Asia changed Europe, opening it up to new ideas and cultures.
Marco Polo was born in the Venetian Republic around 1254．At the time, Venice was one of the most powerful trading cities in the world, and was ruled as an independent city state．Marco’s mother died when he was young, so he was brought up by his aunt and uncle．When Marco was born, his brother (Maffeo) and father (Niccolo), who were successful merchants, were away on a trading voyage．They didn’t get back until Marco was about 15.
In 1271, Niccolo and Maffeo set off again for Asia, this time taking Marco with them．On a previous journey they’d met Kublai Khan (the Yuan Dynasty), and they were keen to establish trade links between Kublai’s empire and Venice．The Polos sailed across the Mediterranean to Acre (now in northern Israel)．Then, they traveled by camel to the port of Hormuz in the Persian Gulf．Their plan was to sail to China but they couldn’t find any good boats．So, they continued the journey overland, finally meeting Kublai Khan at his summer palace in Xanadu, about 275 kms north of modern Beijing．Marco was now probably 21 years ol
The journey had taken over three years.
The Polos had learnt a great deal about the world during their travels and so Kublai employed Marco as a government official．This gave Marco the opportunity to travel around much of Kublai’s empire in China．In fact, Kublai found the Polos so useful that he was unwilling to let them return home．However, in 1292, the Polos eventually left, sailing from China and ending up in Hormuz again．The journey was extremely dangerous: of the 600 travelers who set off, only 18 arrived in Hormuz, including all three of the Polo family．
The Polos finally returned to Venice in 1295, twenty-four years after setting off．They had traveled 24,000 kms．By this time Venice was at war with Genoa, its trade rival．Unfortunately for Marco, he was captured by the Genoese and imprisione
However, he used his time as a prisoner to write a book about his family’s travels: II Milione (known as The Travels of Marco Polo in English)．It was the first book to tell Europeans about China and the East．No original copy survives, but there are several versions of it．Marco’s writings influenced many other travelers, most notably Christopher Columbus, who carried a copy of II Milione with him on his voyage in search of Asia.
After his release from prison in 1299, Marco rejoined his father and uncle in Venice．The family were now even wealthier than before thanks to the many treasures they’d brought back from the East．Marco financed many more trading journeys but never left the city again．He died in 1324 and was buried in the church of San Lorenzo in Venice．
【1】What is the correct order of what Marco Polo has done?
a.met Kublai Khan in Xanadu
b.sailed across the Mediterranean
c.sailed for Hormuz
d.left Venice for Asia
e.went to Hormuz by camel
f.employed as a government official in China
A．b-c-d-f-a-c
B．d-c-b-a-f-e

24、The Health Benefits of Gardening
Gardening is popular in many parts of the world. This outdoor activity gives us beautiful plants, pleasant smelling flowers and fresh fruits and vegetables. 【1】
Reduces loneliness
Gardening connects people. When you are gardening, you are outdoors. 【2】 Most people love to talk about their hobbies, and gardeners are no different. They usually enjoy showing people what they are growing. And most enjoy sharing advice and stories about their gardens.
【3】
Gardening is a great activity to do with children. Children can learn about nature and wildlife. Gardening can teach a child about where food comes from and healthy eating. It can also help them to understand the limits of natural resources and the importance of using them carefully.
Vitamin D
【4】 This means you are getting Vitamin D. Vitamin D helps our bodies use calcium. That is necessary to keep bones strong. Vitamin D also helps us fight diseases.
Exercise
When you garden you must move around. All the different movements needed for gardening — bending, twisting, stretching and lifting — work small muscles in the body. And you can easily get a good work out when you are digging holes or pulling weeds.
Brain health
Gardening may help your brain stay young. Activities such as gardening use many repeated actions, such as weeding or dead-heading (removing dying flowers from a plant). 【5】 The brain is still active but not in the same way that it is, say, when we use computers. In our technology-filled lives, gardening offers a chance to unplug. You cannot hold a phone or other electronic devices when your hands are filled with dirt.
A．Gardening can be a great teacher.
B．But it also gives us many health benefits.
C．Harvests from gardening are organic food.
D．These actions have a calming effect on the brain.
E．So it is a perfect time to socialize with your neighbors.
F．When you are in your garden, you might feel the sunshine on your skin.
G．Gardening can also give you the feeling that you have done something good.
