Fish have different personalities which change as they experience life’s highs and lows.according to British biologists.
Researchers identified different“personalities” in their fish by observing the boldness or shyness of individuals,according to The Nature.Like people,some fish are very confident in the face of novelty(新奇事物)or conflict;while others are silent and fear.
The scientists selected particularly bold and shy rainbow trout,and tested whether they changed their outlook depending on what life threw at them.They arranged some fish to fight and others to watch to see how both the participants and observers responded to victories and defeats.Winning or losing a fight,or even watching fellow fish overcome the difficulties influenced the future behavior of the creatures studied in the lab.
The researchers made fish compete with much larger or smaller opponents.to ensure that they would win or lose their fights.These bold fish that won their fights tended to be even bolder when later presented with a novel food item;losing their fight caused them to be much more cautious.
Fish also learn by watching others.Bold fish watching a shy fish exploring a mystery object were much more nervous when later given a novelty item for themselves.
Predictably,shy fish that won a fight also gained more confidence,but surprisingly,shy fish that lost their fights also grew bolder when exploring strange new food,Sneddon said,adding that this could be due to what she calls a“desperado effect”(亡命徒效应).
The new research suggests that animals can gradually adapt their personalities.The results echo the effects that life experience can have on human.
1.What does.the underlined word“creatures’’probably refer to?

2.The third paragraph of the text is mainly about—————.

高三英语单项填空中等难度题查看答案及解析
I have two sons. They are as different as night and day. My youngest is sweet, loveable, easy-going, and finds joy in everything. My oldest we’ve nicknamed the “Evil Genius” is ambitious, self-confident, and suffers no fools.
Whenever we mentioned Santa my husband and I were rewarded with major eye rolling and deep sighs from my oldest. At first we both tried to ignore it.
We both knew that our eldest had figured out the big secret. But I’d be damned(指责) if he was going to ruin it for his six-year-old brother who had plenty of Santa-loving years ahead of him. I looked at my husband in the eye and said, “I’ll handle this.” to which he responded “Okay just be careful because I’m not sure he knows - he might just be acting like it.” But I knew. And I had it in my mind that he was about to break his younger brothers spirit and break the news to him. I was afraid he was going to take the Christmas spirit away from my sweet innocent youngest and stamp all over it. I had to protect him. I needed to control this now before it got out of control. I rushed into the play room where my oldest was playing alone. I looked him dead in the eyes and said: “Well you know Santa isn’t real, right?” And as I stared at my eight-year-old son for what seemed like a long time of silence, his eyes started to fill with tears. And a tear dropped down his cheek when he screamed out, “He’s not?”
“Um well it’s not that he’s not real (shut up you idiot- stop saying he’s not real), but he doesn’t really make and deliver all the toys. Dad and I get some of them for you. So he’s real. He’s just got a little help from us.”
The Evil Genius wasn’t buying it. He just sat there looking at me with an expression of doubt.
You know when you make a terrible mistake but you can’t stop yourself from making it worse? That was me because I just had to know. I had to know why he had seemed to be over Santa. So I asked him why he rolled his eyes and sighed every time his father and I mentioned Santa, to which he replied that kids at school had been saying Santa wasn't real but that he still thought he was.
1.What’s the best title for the passage?
A. Two different sons
B. Santa secret given away
C. Protecting one, ruining the other
D. Making a mistake worse
2.What did the writer conclude when “Evil Genius” rolled his eyes and sighed?
A. “Evil Genius” had discovered Santa was not real.
B. “Evil Genius” had broken the secret to his younger brother.
C. “Evil Genius” had passed his Santa-loving years.
D. “Evil Genius” had been influenced by his classmates.
3.What does the underlined sentence mean in the passage?
A. “Evil Genius” refused to buy toys.
B. “Evil Genius” didn’t believe his mother’s words.
C. “Evil Genius” wanted to keep silent.
D. “Evil Genius” would not give away the secret.
4.What lesson can we learn from the story?
A. Lies can never change facts.
B. Honesty is the best policy.
C. No one is perfect.
D. We should think twice before we act.

As they reach school age, about 90 percent of children will have experienced a condition in which fluid (液体) fills the middle ear, muffling (使模糊) sound and sometimes causing infection. The fluid usually clears on its own, but if not, it can lead to a painful ear infection called acute otitis (中耳炎) media. In some cases the fluid can persist for more than a year, causing hearing loss during this period, and slowing down their development of language and social skills.
Diagnosis usually requires a visit to a specialist—but researchers have now developed an app that detects this fluid just as accurately, with only a smartphone and a paper funnel (漏斗).
Doctors typically detect the problem by peering into the ear for a visual assessment. Yet, this method has only a 50 percent accuracy rate. “Right now, if you bring your child to a pediatrician, or to any urgent care family doctor, the way they look at whether or not there’s fluid in the middle ear is by looking at the eardrum,” says Sharat Raju, a surgeon in the department of head and neck surgery at the University of Washington.
For a cheaper and more accessible alternative, researchers at the University of Washington turned to smartphones. First the user follows a template to cut and tape a piece of paper into a funnel, which can be placed between a smartphone and the patient’s ear. Next the app plays a chirping sound through the phone’s speaker; the sound waves bounce off the eardrum and hit the phone’s microphone, where they register and are analyzed by the app. An eardrum with fluid behind it will vibrate (振动) differently than if the middle ear is full of air, as it normally is.
To develop the app, the researchers first played chirps for patients with and without fluid in their ears. They recorded the echoes (回音), which indicate the eardrum’s mobility. Then they used a machine learning model to classify the returning sound waves, determining which audio characteristics indicated a normal ear and which suggested the presence of fluid. Once they tested the app on 98 children, ranging from 18 months to 17 years old, at Seattle Children’s Hospital. It correctly detected fluid in 85 percent of cases, and correctly identified fluid-free ears in 82 percent.
The researchers are currently trying to get FDA approval for the app, and have founded a company to commercialize it. They hope to make it available by the end of the year, to help parents track children’s ear health at home.
1.What do we know about the fluid from the first paragraph?
A.It is mostly part of children’s growth. B.It is unavoidable for any child.
C.It is a permanent physical condition. D.It is beyond any medical means.
2.What does the underlined word “pediatrician” refer to in Paragraph 3?
A.A hospital. B.A specialist.
C.A relative. D.An app.
3.What is the fourth paragraph mainly about?
A.The application of the app. B.The causes of the kid’s ear problem.
C.The purpose of developing the app. D.The experiment of the smartphone.
4.What do the researchers expect of the app?
A.It will upgrade the medical technology. B.It will hit the market in the near future.
C.It will help children do better academically. D.It will save doctors medical operations.

Improve your job chances. 2.. HR managers value international experience highly, as candidates with experiences of studying abroad are considered to be adaptable, independent, problem-solving and open.
