1 . The public must be able to understand the basics of science to make informed decisions. Perhaps the most dramatic example of the negative consequences of poor communication between scientists and the public is the issue of climate change, where a variety of factors has contributed to widespread mistrust and misunderstanding of scientists and their research. The issue of climate change also illustrates how the public acceptance and understanding of science (or the lack of it) can influence governmental decision-making with regard to regulation, science policy and research funding.

However, the importance of effective communication with a general audience is not limited to hot issues like climate change. It is also critical for issues such as the genetic basis for a particular behavior or the use of animal models because in these areas, the public understanding of science can also influence policy and funding decisions. Furthermore, with continuing scientific advances, more non-scientists will need to be able to analyze complex scientific information to make decisions that directly affect their quality of life.

Science journalism is the main channel for the popularization of scientific information among the public. Much has been written about how the relationship between scientists and the media can shape the efficient communication of scientific advances to the public. Good science journalists are specialists in making complex topics accessible to a general audience, while sticking to scientific accuracy. Unfortunately, pieces of science journalism can also oversimplify and generalize their subject material. As a result, the basic information conveyed is difficult to understand or obviously wrong.

Even though scientists play a part in conveying information to journalists and ultimately the public, too often the blame for ineffective communication is placed on the side of the journalists. I believe that, at least in part, the problem lies in places other than the interaction between scientists and members of the media. It exists because we underestimate how difficult it is for scientists to communicate effectively with a diversity of audiences, and most scientists do not receive formal training in science communication.

2 . A few years ago, a young woman at Facebook came to my desk and asked if she could speak privately. We headed into a conference room, where she began firing off questions about how I balance work and family. As the questions came faster and faster, I started to wonder about her urgency. I interrupted to ask if she had a child. She said no, but she liked to plan ahead. I inquired if she and her partner were considering having a child. She replied that she did not have a husband, then added with a little laugh, “Actually, I don’t even have a boyfriend.”

It seemed to me that she was jumping the gun but I understood why. From an early age, girls get the message that they will have to choose between succeeding at work and being a good mother. By the time they are in college, women are already thinking about the trade-offs they will make between professional and personal goals! When asked to choose between marriage and career, female college students are twice as likely to choose marriage as their male classmates. And this concern can start even younger. Peggy Orenstein, the author of Cinderella Ate My Daughter, related the story of a five-year-old girl who came home distraught from her after-school program and told her mother that both she and the boy she had a crush on wanted to be astronauts.When her mother asked why that was a problem, the little girl replied, “When we go into space together,who will watch out kids?” At five,she thought the most challenging aspect of space travel would be dependable childcare.

As I’ve mentioned, I’m a big believe in thoughtful preparation. Everywhere I go, I carry a little notebook with my to-do list. But when it comes to integrating career and family, planning too far in advance can close doors rather than open them. I have seen this happen over and over. Women rarely make one big decision to leave the workforce. Instead, they make a lot of small decision along the way, making accommodations and sacrifices that they believe will be required to have a family. Of all the ways women hold themselves back, perhaps the most pervasive is that they leave before they leave.

1. What does the underlined sentence in paragraph two “she was jumping the gun” mean in the passage?

A．She was taking action before everyone else did.

B．She was making preparations earlier than she was supposed to.

C．She was reluctant to make the decisions all by herself.

D．She was wondering how to balance work and family.

2. What is paragraph two mainly about?

A．After-school programs in primary schools encourage children to picture their future life.

B．Domestic life is preventing women nowadays from pursuing higher goals in workplaces.

C．Females nowadays start to weigh their choice between family and career at an even earlier age.

D．Female college students are more willing to assume domestic responsibilities than their male classmates.

3. What does the underlined word “distraught” in paragraph two mean?

A．upset

B．delighted

C．satisfied

D．excited

4. Which of the following statements would the author probably agree with?

A．Females are advised to make life-decisions after thoughtful preparation.

B．It’s better for girls to plan for leaving the workplace step by step.

C．Women usually make up the their mind to quit their job in a very short period of time.

D．Planning too early for balancing career and family is hindering females from promotion in the workplace.

4 . At the start of every vacation, many parents spend their time wondering: What will the children do? When I was a child in the 1950s, the answer was easy. The children would play. We played feely with other children, in our own chosen ways, away from adults. When we got bored, we found ways to overcome it. We took up _________, took risks, sometimes hurt ourselves, got into trouble, and _________ how to get out of it.

During such play, we acquired knowledge and skills that couldn’t be taught to us in school. We learned how to take _________, make our own decisions, solve our own problems, get along with peers as equals, experience fear and then find ways to manage it, experience anger and then find ways to overcome it. We also discovered our interests, _________ them, and became skilled at them—interests that for many of us later became _________.

Over the past 60 years, however, we’ve seen a huge _________ in children’s freedom and opportunity to play on their own. Over this same period, we’ve also seen a dramatic increase in the rates of _________ and anxiety disorders among young people- five to eight times what they were in the 1950s.

Our children love to play in moderately _________ ways. Through such play, they acquire the physical, social and emotional capacities required for healthy development. They learn to get along with one another by playing socially, and they learn to deal with emergencies by playing in ways that involve risk.

Why is such play so _________? It can cause injury, so why hasn’t natural selection __________ the inner desire for it? We have some clues from laboratory experiments.

Researchers have found that when young rats or monkeys are deprived (剥夺) of play during critical periods in their development, the animals grow up as emotional cripples (跛者). They are __________ disabled when placed in new, slightly frightening environments to which normally raised animals would __________. They repeated between incapacitating fear and inappropriate aggression when placed with __________ peers. So it is no surprise to me that play-deprived human children grow up insufficient in the social and emotional skills required to deal well with life’s inevitable stressors (应激源). They may also grow up __________ the abilities to think creatively, take initiative, and assume responsibility.

We have deprived children of free, risky play, probably for their own good. In the process we have denied them the opportunity to learn how to be __________ by playing in risky ways.

Our children need more freedom, not more adult control.

5 . Science may never know what memories play on the mind of the California sea hare, a foot-long marine snail, when it eats algae — a sea plant — in the tide pools of the Pacific coast.

But in a new study, researchers claim to have made headway in understanding the simplest kind of memory a creature might form.

David Glanzman, a neurobiologist at the University of California, believes the kinds of memories that trigger a defensive reaction in the snail are encoded not in the connections between brain cells, as many scientists would argue, but in RNA molecules (分子) that form part of an organism’s genetic machinery.

In an experiment to test the idea, Glanzman implanted wire into the tails of California sea hares, and gave them a series of electrical shocks. The procedure sensitized the animals so that when they were prodded (戳) in a fleshy spout called a siphon, they contracted their gills (鳃状呼吸器官) in a strong defensive action.

After sensitizing the sea snails, Glanzman extracted RNA from the animals and injected it into other sea snails to see what happened. He found the recipient sea snails became sensitized, suggesting the “memory” of the electrical shocks had been transplanted. When Glanzman repeated the experiment with RNA from sea snails that had been hooked up to wires but not shocked, the reaction behavior did not transfer.

Despite the result, the work has not found widespread acceptance. “Obviously further work needs to be carried out to determine whether these changes can happen without failure in a wide range of conditions,” said Prof Sherilynn Vann, who studies memory at Cardiff University. “While the sea hare is a fantastic model for studying basic neuroscience, we must be very cautious in drawing comparisons to human memory processes.”

Tomas Ryan, who studies memory at Trinity College Dublin, is firmly unconvinced. “It’s interesting, but I don’t think they’ve transferred a memory,” he said. “This work tells me that maybe the most basic behavioral responses involve some kind of switch in the animal and there is something in the liquid that Glanzman extracts that is hitting that switch.”

But Ryan added that different thinking about memory was badly needed: “In a field like this which is so full of accepted beliefs, we need as many new ideas as possible. This work takes us down an interesting road, but I have a huge amount of skepticism about it.”

1. Why were the sea hares given electrical shocks?

A．To rob them of their memory.

B．To see how they defend themselves.

C．To break the connection between nerves.

D．To make them sensitive to external stimulations.

2. What conclusion may Glanzman draw from the experiment?

A．Memory can be encoded and changed by people.

B．Only with strong stimulation can sea snails form reaction.

C．The memory giving rise to sea snail’s sensitization is held in RNA.

D．The sea snail’s defense is probably enabled by connectivity of brain cells.

3. According to the passage, the limitations of Glanzman’s experiment involve the following EXCEPT ________.

A．The recipient sea snail’s response may require further confirmation.

B．Variables (变量) in the experiments may not have remained the same.

C．Something else other than RNA in the extract may lead to the recipient’s reaction.

D．The sea snail “memory transplant” may not apply to more complex memory process.

4. The underlined word “skepticism” in the last paragraph is closest in meaning to ________.

A．criticism

B．doubt

C．relief

D．optimism

6 . The Decision That Changed My Life

We make decisions every day. Whether it is a small decision like what to wear that day or a big decision like where to go to college, these decisions have at least some influence on the rest of our lives. I wanted to talk about a decision I made that has changed my life forever.    1    I know that it seems like such a tiny decision, but it truly has changed my life.

I gave up soda about a month and a half before my trip to the Bahamas as a healthy step towards “getting in shape” for my trip. At first I thought it was going to be really hard giving it up, but after that first two weeks I wasn’t thinking about soda at all. One tiling led to another and I started eating better, working out more and just generally living a healthier life. I had already seen a difference in my life following this healthier life style.    2     During my trip I was extremely tempted to drink soda because all we were drinking was water.    3    

That was because I wanted to show those who maybe thought I wouldn’t be able to do it that they were wrong. Soon the urge to drink soda somewhat disappeared and I really did not even become tempted by it by the end of the trip. I got home to the States and when I got back home I decided to weigh myself. I had lost 20 pounds on my trip!

I also wanted to give some advice for those who were in the same situation as I was, where you wanted/needed to give up something that you think you can’t live without.    4     My friends really helped me out by supporting me and reminding me of the reason why I was doing it. Lastly, remember why you are giving it up. Use the goal of you losing weight or being generally healthier to motivate you through the struggle. In the end, giving up soda changed my life and I don’t regret my decision what so ever.

A．You need a support system.

B．I almost gave up a couple of times but stayed strong.

C．I felt happier, more energized and just all around better.

D．Weeks and weeks went by and I still was not missing drinking soda.

E．I hope you are inspired by my story to give up something that is bad for you.

7 . Trying to make a big decision while you’re also preparing for a scary presentation? You might want to ______ doing that. Most people prefer to have sufficient time to analyze a situation and consider the ______. Feeling stressed changes how people ______ risk and reward. A new article published in Current Directions in Psychological Science reviews how, under stress, people pay more attention to the ______ of a possible outcome. Pressure can result in ______ attention and the use of unconscious reasoning. It can force a decision-maker to sort the relevant factors from the irrelevant, and can ______ clear thinking with specific priorities. 

It’s a bit ______ that stress makes people focus on the way things could go right, says Mara Mather of the University of Southern California. “This is sort of not what people would think,” Mather says, “Stress is usually associated with disagreeable experiences, so you’d think that maybe I’m going to be more focused on the ______ outcomes.” But researchers have found that when people are under stress — by being told to hold their hand in ice water for a few minutes, for example, or give a speech — they start paying more attention to positive information and ______ negative information. “Stress seems to worsen their learning from negative feedback,” Mather says. This means when people under stress are making a difficult decision, they may pay more attention to the upsides of the alternatives they’re considering and less to the downsides. So someone who’s deciding whether to take a new job and is feeling stressed by the ______ might weigh the increase in salary more heavily than the worse commute (通勤)。

The increased focus on the positive also helps explain why stress plays a role in ______, and people under stress have a harder time controlling their urges. “The compulsion to get the reward comes stronger and they’re less able to ______ it,” Mather says. So a person who’s under stress might think only about the good feelings they’ll get from negative things like a drug, while the ______ shrink to the distance.

Stress also ______ the differences in how men and women think about risk. When men are under stress, they become even more ______ to take risks; when women are stressed, they get more conservative. Mather links this to another research that finds, at difficult times, men tend to face the situation, while women are likely to be more conservative.

8 . Chances are you’re quite bored of your home by now. Oh sure, you know how lucky you are, if you have a warm and comfortable place to live when so many don’t. But a person could live in a full-on palace and still, at this point in a generation-defining global pandemic, think, “If I have to spend one more day looking at this cornicing (榐板) and those enormous wall sconces (壁式烛台), I will genuinely hurl myself off the balcony.” So allow me to share the greatest tip of all time for making your home more fun: get some wallpaper.

People are very cautious about wallpaper, especially the patterned type. I didn’t fully understand this until my partner and I were house–hunting half a decade ago, after we found out I was expecting twins. Off we went to look at family houses and, while the prices were horrific, the houses were, to my mind, even worse. That’s not fair: they were perfectly fine, but there was something about them that sent me plunging into a low-grade depression. I tried to explain it to the increasingly frustrated estate agents: maybe they were dark? Or they just had a bad atmosphere? Were the ceilings too low? At last, I understood: every house I looked at was painted all white or–worse!–dull grey. Literally, every single one, and I assume the people who lived in them thought they looked fashionable and safely neutral. To me they brought back memories of teenage years spent in a psychiatric unit (精神病病房).

“Safely neutral”: has there ever been a more depressing template (样板) for a home? “Safely neutral” is timidity, the decorating equivalent of a fear of letting yourself have fun in case people laugh at you, or a refusal to state an opinion in case you get it wrong. How so many people can bear to live like that is beyond my comprehension. I know not everyone is a maximalist, but I find it puzzling that people won’t commit to patterned wallpaper because they worry they’ll get tired of it, yet paint their home in the most boring shades possible. Be your fearless self! Make your stamp! If not on the world, then at least on your walls.

By the time we moved into our (entirely white, God help me) house, I was a month away from giving birth to two surprisingly big boys. I could no longer walk, but this in no way broke my stride when it came to sorting out the wallpaper. This was a home I hoped to live in for the next two decades, so I went all out and spent so much on wallpaper that we couldn’t really afford furniture for a while.

1. It can be learned from paragraph 2 that ________.

A．the estate agents finally figured out why the author didn’t like the houses

B．the unaffordable housing prices sent the author into a minor depression

C．the houses the author was hunting turned out to be disappointingly uniform

D．the teenager experience of being in a psychiatric unit troubled the author

2. What does the author think of “safely neutral”?

A．It may bring about ridicule from others.

B．It will make a home much less depressing.

C．It is too abstract for people to understand.

D．It robs us of the chance to pursue pleasure.

3. The underlined sentence in paragraph 3 can be best illustrated as ________.

A．throwing away the apple due to the core	B．dealing with a man as he deals with you
C．killing two birds with one stone	D．cherishing imaginary or groundless fears

4. What’s the purpose of the passage?

A．To highlight the vital importance of wallpaper.

B．To reveal how to add color to home decoration.

C．To indicate why people tend to get depressed.

D．To explain what safe neutrality is all about.
