1 . I took a job as a receptionist for a pet doctor almost five decades ago. As an eager animal lover, I accepted the _______ on condition that I wouldn’t have to assist with any wounded animals. I couldn’t bear to see any creature in _______.

At the end of my first week, we were closing the office for the day when a young man ran up to us holding a severely _______ Doberman pinscher puppy (杜宾犬) in his arms and _______ us to save his life. The four-month-old puppy had been hit by a car. The doctor and I ran back into the _______ room. The doctor worked _______ for what seemed like hours, stitching (缝合) him back together again. That was the _______ part. The puppy had broken multiple bones, including his backbone. Even if he _______ the next few days, we were quite sure he would never walk again.

That day forever _______ my life. The doctor guided me, and I became his ________ in all things medical. One of my first jobs was to give that Doberman puppy daily physical treatment. I remember moving his ________ legs to try to keep his muscles from weakening. Weeks went by until one day, I felt this little ________ push back ever so slightly. And he continued to push back till he could finally use his legs.

Fast-forward about a year. I walked into the clinic’s crowded waiting room and called the name of the next client. ________, a huge Doberman standing quietly with his owner on the opposite side of the room ________ and dashed toward me. I found myself pressed against the wall with this magnificent dog ________ on his back legs, his front paws on my shoulders, ________ my face with countless and ________ kisses!

I still tear up in ________ at the display of love and ________ the dog had for me that day all those years ago. I went on to be a pet doctor for 14 years until retirement. In all the time that has passed and all the experiences I have had, I’ve ________ met a dog who didn’t know it had been rescued in one way or another.

4 . 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.

5 . Challenging work that requires lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age, a study published Wednesday in the journal Neurology suggests.

Researchers from the University of Leipzig in Germany gathered more than 1, 000 retired workers who were over age 75 and assessed the volunteers’ memory and thinking skills through a battery of tests. Then, for eight years, the scientists asked the same group to come back to the lab every 18 months to take the same sorts of tests.

Those who had held mentally stimulating(刺激), demanding jobs before retirement tended to do the best on the tests. And they tended to lose cognitive(认知) function at a much slower rate than those with the least mentally challenging jobs. The results held true even after the scientists accounted for the participants’ overall health status.

“This works just like physical exercise, ” says Francisca Then, who led the study. “After a long run, you may feel like you’re in pain, you may feel tired. But it makes you fit. After a long day at work-sure, you will feel tired, but it can help your brain stay healthy. ”

It's not just corporate jobs, or even paid work that can help keep your brain fit, Then points out. A waiter’s job, for example, that requires multitasking, teamwork and decision-making could be just as stimulating as any high-level office work. And “running a family household requires high-level planning and coordinating(协调), ” she says. “You have to organize the activities of the children and take care of the bills and groceries. ”

Of course, our brains can decline as we grow older for lots of reasons-including other environmental influences or genetic factors. Still, continuing to challenge yourself mentally and keeping your mind busy can only help.

1. Why did the scientists ask the volunteers to take the tests?

A．To assess their health status.	B．To evaluate their work habits.
C．To analyze their personality.	D．To measure their mental ability.

2. How does Francisca Then explain her findings in paragraph 4?

A．By using an expert’s words.	B．By making a comparison.
C．By referring to another study.	D．By introducing a concept.

3. Which of the following is the best title for the text?

A．Retired Workers Can Pick Up New Skills

B．Old People Should Take Challenging Jobs

C．Your Tough Job Might Help Keep You Sharp

D．Cognitive Function May Decline As You Age

6 . I experienced years of loneliness as a child.     1     His friends teased him about babysitting his sister and his interests were far different from mine. With no other kids of my age in the neighborhood, I had to spend hours by myself.

A bright spot for me turned out to be reading. My love of the written word began early as my mother read to me every evening.     2     I started reading books on my own before age 5 and my mother took me to the public library once a week to borrow several books. I quickly graduated from typical children’s books to ones with fewer pictures and longer chapters. Reading opened new worlds to me.     3    

My mother also encouraged me to make what I wanted. I tried making toy cars with cardboard boxes and constructing buildings from leftover cardboard and bits of wood my father gave me. When my mother saw my creations, she told me how creative my designs were.     4     I learned a lot about how to extend the life of objects and transform them into something new and useful. It was a trait(特点) others found helpful, and I soon had friends who wanted to make things with me.

    5    My parents made it a point for their two kids to spend time outside, no matter the weather or season. My brother, of course, raced off to be with his friends, while I had plenty to do myself. There was making leaf houses in autumn, ice skating in winter, and so much more. They’re all memories I treasure today.

A．I wasn't alone any longer.

B．I enjoyed reading stories aloud.

C．I was invited to play with another kid.

D．I loved the colorful photographs in the books.

E．Another habit I formed early was being outdoors.

F．Thus, I began my lifelong interest in making things.

G．My older brother couldn’t be bothered to play with me.

7 . We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.

On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.

Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”

In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.

1. What does the author want to tell us by the examples in paragraph 1?

A．Environmental adaptation of cattle raisers.	B．New knowledge of human evolution.
C．Recent findings of human origin.	D．Significance of food selection.

2. Where do the Bajau build their houses?

A．In valleys.

B．Near rivers.

C．On the beach.

D．Off the coast.

3. Why was the young Jubilado astonished at the Bajau?

A．They could walk on stilts all day.	B．They had a superb way of fishing.
C．They could stay long underwater.	D．They lived on both land and water.

4. What can be a suitable title for the text?

A．Bodies Remodeled for a Life at Sea	B．Highlanders’ Survival Skills
C．Basic Methods of Genetic Research	D．The World’s Best Divers

8 . The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.

The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.

One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.

In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.

Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.

1. What is the first paragraph mainly about?

A．A new study of different plants.

B．A big fall in crime rates.

C．Employees from various workplaces.

D．Benefits from green plants.

2. What is the function of the sensors printed on plant leaves by MIT engineer?

A．To detect plants’ lack of water

B．To change compositions of plants

C．To make the life of plants longer.

D．To test chemicals in plants.

3. What can we expect of the glowing plants in the future?

A．They will speed up energy production.

B．They may transmit electricity to the home.

C．They might help reduce energy consumption.

D．They could take the place of power plants.

4. Which of the following can be the best title for the text?

A．Can we grow more glowing plants?

B．How do we live with glowing plants?

C．Could glowing plants replace lamps?

D．How are glowing plants made pollution-free?

9 . When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).

Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.

Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.

Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.

The fur trade kept nutria in check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.

Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.

Then there’s Righteous Fur and its unusual fashion. Model Paige Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them-I think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She is trying to come up with a label to attach to nutria fashions to show it is eco-friendly.

1. What is the purpose of the fashion shows in New Orleans and Brooklyn?

A．To promote guilt-free fur.

B．To expand the fashion market.

C．To introduce a new brand.

D．To celebrate a winter holiday.

2. Why are scientists concerned about nutria?

A．Nutria damage the ecosystem seriously.

B．Nutria are an endangered species.

C．Nutria hurt local cat-sized animals.

D．Nutria are illegally hunted.

3. What does the underlined word “collapsed” in paragraph 5 probably mean?

A．Boomed.

B．Became mature.

C．Remained stable.

D．Crashed.

4. What can we infer about wearing fur in New York according to Morgan?

A．It’s formal.

B．It’s risky.

C．It’s harmful.

D．It’s traditional.

10 . If you associate modern British fiction with the cool, lonely tones of Martin Amis and Julian Barnes, and US fiction with Jonathan Franzen’s _______inner worlds or John Irving’s sentimentality, it seems you have good _______.
