On Tuesday August 11th, 1911, in the room where the world’s most famous painting, the Mona Lisa by Leonardo da Vinci, was on display, there was an empty space where the painting should have been．The next day headlines all over the world announced the theft．

Actually the Leonardo had been long gone．The museum was always closed on Mondays for maintenance(维修)．Just before closing time on Sunday three men had entered the museum, and hid themselves in a storeroom．Early next morning, they took the painting and left．

Nothing was seen or heard of the painting for two years until Perrugia tried to sell it to a dealer for half a million lire．Perrugia was arrested and imprisoned for seven months．It seemed that the crime of the century had been solved．

But had it? Perrugia claimed all responsibility for the theft, and it was twenty years before the whole story came out．In fact Perrugia had been working for Valfierno and Chaudron, who went unpunished for their crime．They would offer to steal a famous painting from a gallery(美术馆) for a dishonest dealer or private collector．They would then make a copy of the picture and, with the help of bribed(受贿的) gallery workers, would then attach the copy to the back of the original painting．The dealer would then be taken to the gallery and make a secret mark on the back of the painting．Of course the dealer would actually be marking the copy．After having been given the marked painting, if the dealer were to see the painting still in the gallery, he would be persuaded that it was a copy, and that he possessed the genuine one．

This time, however, they stole the original．Before Perrugia was arrested, Valfierno and Chaudron had gone to New York．Valfierno told the story to a journalist in 1914, on condition that it would not be published until his death．

Does the story end there? Collectors have claimed that Perrugia returned a copy．It is also possible that Leonardo may have painted several versions of the Mona Lisa, or they might be copies made by Leonardo’s pupils．There has been a lot of argument about the 450-year-old painting, but after all, maybe that’s what she’s smiling about．

1.The Mona Lisa was stolen on _________．

A．August 9^th            B．August 10^th       C．August 11^th       D．August 12^th

2.Choose the right time order of the following events．

a．Valfierno told the story to a journalist．   b．Perrugia was arrested．

c．The truth was published．                d．The Mona Lisa was stolen．

e．Valfierno went to New York．         f．The theft was announced．

A．d, f, b, e, a, c     B．d, f, e, b, a, c     C．d, f, b, e, c, a     D．f, d, e, b, c, a

3.We can infer from the passage that _________．

A．In most cases, Valfierno did not sell the original paintings

B．The Mona Lisa was painted 45 years ago

C．Perrugia returned a copy

D．Perrugia was not to blame for the theft

4.All of the following about Valfierno and Chaudron are true EXCEPT_________．

A．They stole paintings and then sold them to dishonest dealers．

Described as the world’s most environmentally friendly protein, Solein is made by applying electricity to water to release bubbles of carbon dioxide and hydrogen. Living microbes(微生物) are then added to the liquid to feed on the carbon dioxide and hydrogen bubbles and produce the Solein, which is then dried to make the powder. It’s a natural fermentation(发酵) process similar to beer brewing. The dried Solein has a protein content of 50 percent and looks and tastes just like wheat flour.

“It is a completely new kind of food, a new kind of protein, different to all the food on the market todav in how it is produced as it does not need agriculture.” Dr Pasi Vinikka, the chief executive of Solar Foods told The Guardian. The process used to produce Solein — converting hydrogen and carbon dioxide to calories — is amazing, as the wonder food can be produced anywhere in the world. It’s also 10 times more energy-efficient per hectare than photosynthesis (光合作用), and 10 to 100 times more environment and climate-friendly in water use than animal or plant based food production.

“Solein also contains all the essential amino acids(氨基酸), but because it is produced using carbon dioxide and electricity, it does not require large amounts of land to produce,” the Solar Foods website explains. “Another unique characteristic of Solein is that it is able to take carbon directly from carbon dioxide without needing a source of sugar.”

While Solar Foods does not expect Solein to challenge conventional protein production methods in the next two decades, it does expect it to become a “new harvest” for humanity, which is significant considering so far we have only relied on plants and animals for sustenance. The Helsinki-based company plans to open its first Solein factory at the end of 2021 and scale up production to two billion meals per year by 2022.

1.Which of the following statements best describe the features of Solein?

A.It is a new kind of food containing all the nutrition.

B.It is made from water and carbon dioxide by applying electricity.

C.It is produced without consuming much land and energy.

D.It is a kind of man-made wheat flour.

2.What does the underlined word “converting” mean?

A.relating B.changing

C.contributing D.adapting

3.What can be inferred from the last paragraph?

A.The company thinks Solein would have a rewarding future.

B.Solein is supposed to challenge traditional protein production.

C.There is still a long way for Solein to be put into production.

D.Humans can completely rely on Solein to survive.

4.What’s the author’s purpose in writing this passage?

A.To promote a new kind of technology.

B.To introduce a new kind of food.

C.To make an ad for a new kind of protein.

D.To call on people to protect the environment.

A population of the world's most aggressive mosquito species was almost completely wiped out by an experiment on two islands in the southern Chinese province of Guangdong, according to a study published.

The experiment successfully reduced the female Asian Tiger Mosquito population — the main source of bites and disease spread — by up to 94%, reducing the number of reported human bites by 97%.

One of the Chinese study's researchers, Xi Zhiyong, a professor at Michigan State University, has been a longtime pioneer in this field of study. Running a mosquito factory in southern China, he previously attempted to use sterilized male mosquitoes to mate with unaltered females which developed normally. In the new study, published by the International Journal of Science, Xi and his colleagues attempted to cut mosquito numbers even further by limiting both males and females' ability to reproduce. The results were so successful that they nearly killed the entire female mosquito population on the two islands.

It isn't the first attempt by researchers to reduce mosquito populations across the world. In 2018, scientists from the Imperial College of London used gene-editing tools to make female mosquitoes sterile, while males developed normally and continued spreading the genetic mutation (突变).Experts said the Asian Tiger Mosquitoes are particularly hard to kill using traditional population control methods, such as pesticides (杀虫剂) and removing stagnant (不流动的) water where the insects lay their eggs.

Mosquitoes create grave threats to human health beyond just bites. The World Health Organization (WHO) has described the insects as "one of the deadliest animals in the world," due to their ability to rapidly spread deadly diseases such as dengue fever and malaria. There is currently no effective vaccine or treatment for most mosquito-spread diseases, leaving controlling the insects' populations one of the most effective control methods, according to the International Journal of Science. “A new tool like what's being described in this paper is very much needed” said Stephen Dobson, a professor of medical insectology at University of Kentucky.

1.What does the underlined word "unaltered" in paragraph 3 refer to?

A.Unchanged. B.Undivided.

C.Unadopted. D.Unfinished.

2.Why do mosquito populations have to be controlled?

A.Mosquitoes cause genetic changes in humans.

B.Mosquitoes spread some deadliest diseases.

C.Mosquitoes limit people's ability to reproduce.

D.Mosquitoes make traditional vaccines ineffective.

3.What has been the most successful way of reducing mosquito numbers?

A.Editing genes in female mosquitoes.

B.Sterilizing male mosquitoes before mating.

C.Limiting both genders' reproduction ability.

D.Using pesticides and removing stagnant water.

4.What can we learn from Stephen Dobson's words?

A.The things described in this paper are not practical.

B.A better way of mosquito control is yet to be found.

C.Xi Zhiyong' s method has proven to be very effective.

D.A new tool is needed in order to improve Xi's research.

There are two main types of office layouts used by most companies around the world: Landscape Office and Enclosed Office. A landscape office lacks privacy, however, this office layout is more beneficial than an enclosed office for employees to improve work efficiency and productivity.

Some people might desire an undisturbed workplace. According to the survey collected from a company with the two kinds of office layouts, most of managers prefer a workplace where they can concentrate on their work and make a clear thinking. However, managers that possess their own enclosed offices might have the feeling of being distant from their clerks, which leads to high pressure. Meanwhile, employees tend to be nervous when they have conversations with their managers in an obviously hierarchical(等级制的) environment. In contrast, a landscape office makes it easier and more pleasant for employees to communicate with their managers or their colleagues; this would result in speeding up work efficiency and productivity.

Besides, greater interaction is beneficial for employees to build up friendship in a landscape office. This can be proved by the experiment of Brookes and Kaplan. They recorded the attitudes and opinions of 120 employees toward their enclosed office before they moved to the landscape office, and then after nine months they were tested again. The researchers discovered that those employees performed positive changes in group sociability. When people have better group sociability, they experience a better team work and efficient cooperation, which surely promotes work productivity.

Some opponents claim that a landscape office would lead to the decline of the value of work satisfaction and motivation from employees. However, the result from other researchers remained controversial; in their opinion there are several factors which affect job satisfaction and motivation. 600 Canadian federal government department workers who were housed at a modern landscape office and were surveyed gave both negative and positive feedback. They admitted that they felt the sense of belonging to a team or a working community, which mainly contributes to job satisfaction. Motivation is also increased by a sense of responsibility for and loyalty to a team.

Admittedly, there are some advantages that only enclosed offices possess. However, a landscape office can combine the features of the traditional enclosed office, for example, designing the independent meeting room to decrease noise from discussion. Although the benefits of a landscape office outweigh those of an enclosed office, which layout is better should be decided by the characteristics of the people and the type of work they do.

1.What is mainly talked about in the passage?

A.Colleague cooperation and its motivation.

B.Group sociability and its productivity.

C.Working environment and its effect.

D.Office privacy and its atmosphere.

2.What has the significant effect on productivity according to Paragraph 2?

A.Job satisfaction. B.Relaxed atmosphere.

C.Group sociability. D.Undisturbed workplace.

3.What can be inferred from the passage?

A.Enclosed office leads to individual creativity.

B.Different working styles in enclosed office is encouraged.

C.Landscape office contributes to effective conversations.

D.Frequent communication in landscape office results in high pressure.

4.What is the author’s attitude towards office layouts?

A.Objective. B.Casual. C.Optimistic. D.Sceptical.

Mom was a teacher most of her life. When she wasn’t in the classroom, she was educating her children or grandchildren: correcting our grammar; starting us on collections of butterflies, flowers or rocks; or inspiring a discussion on her most recent “Book of the Month Club” topic. Mom made learning fun.

It was sad for my three brothers and me to see her ailing in her later years. At eighty-five, she suffered a stroke and she went steadily downhill after that.

Two days before she died, my brothers and I met at her nursing home and took her for a short ride in a wheelchair. While we waited for the staff to lift her limp body back into bed, Mom fell asleep. Not wanting to wake her, we moved to the far end of the room and spoke softly.

After several minutes our conversation was interrupted by a muffled sound coming from across the room. We stopped talking and looked at Mom. Her eyes were closed, but she was clearly trying to communicate with us. We went to her side.

“Whirr,” she said weakly.

“Where?” I asked. “Mom, is there something you want?” “Whirr,” she repeated a bit stronger. My brothers and I looked at each other and shook our heads sadly.

Mom opened her eyes, sighed, and with all the energy she could muster said, “Not was, say were!”

It suddenly occurred to us that Mom was correcting brother Jim’s last sentence. “If it was up to me…”

Jim leaned down and kissed her cheek. “Thanks, Mom,” he whispered. We smiled at each other and once again shook our heads…this time in awe of a remarkable teacher.
