Last Saturday my classmates and I went to the park nearby．We went there not for amuse but to take part in voluntary labor．
We got there at 9：00．We were dividing into three groups and then began working separate．The students in Group One collected the litter leave about by tourists．The task for Group Two was cleaning the bench．The group I was in get to the Children’s Playground and wiped all the equipment clean．They worked very hard．At 11：00,all the work was finished and park looked much more beautifully．Although we were tired, but we felt happy because we had done a good deed.
The Most Valuable Skill
My grandmother, who had Alzheimer disease, got worse two years ago. My father had her taken good care of in a famous nursing home nearby. My grandmother was a retired university professor, which often made her have an ocean of_________who she had taught before. The old man next door almost had no visitors at all, in deep_________with my grandmother. When I kept her company, he was always_________,sitting on his wheelchair and bathing himself in the sunshine.
Once I_________him, “How are you doing recently?” He gave me a look, but said nothing. I thought he could not hear well, so I_________my voice, “I was asking, ‘How are you doing recently?’” He_________ his head slightly. After a long while finding I was still there, he just said, “Fine.” Then he looked away. I had to choose to _________.
Later, a nurse accidentally told me that the old man had been a businessman, after getting tons of money and companies._________ he was not a good speaker, he annoyed many people and _________made his family and friends pull away. Then he went broke.
That day, my father asked, “What is the most valuable__________a person can have for their entire life?” Before I answered, he continued, “You think making money is the answer. huh? No! But the ability to express your __________is. Seriously, I believe this is something most of us__________.”
It’s extremely__________for a person to learn to put into words, what he thinks. It makes a relationship__________. It creates a(n) __________on the person you’re talking to. It gives you a chance to__________what others think about your ideas. It lets you say something in a________ other people understand. How many of us have said something that has__________whoever loves us deeply? Whatever you say, on purpose or__________,will matter.
So Hemingway concluded, “It takes two years to learn to __________,and a lifetime to learn to shut up.”

How do you react to challenges? Do you run and hide, or do you face them with your head held high? Having confidence in yourself can give you power to face challenges and succeed in the following two aspects of life.
1.
Everyone knows that looking confident during a job interview will help you get the job. Confidence actually can help you in your career. In other words, if you think you’ll succeed in your workplace, it’s more likely that you will succeed one day.
Social skills
Being sure of yourself can also 1nake you feel calm when meeting new people. You’ll be less afraid of rejection, so you’ll be free to be yourself. 2.. Your nice image will make them more willing to interact with you.
But how to develop your confidence?
● 3.. Make a list of your strengths and weaknesses。 Being confident doesn’t mean you have to be blind to problems you have。 But you want balance. Be sure to think of a strength for every weakness you write down.
● Set goals. Make some goals for your daily tasks. If you could accomplish anything in life, what would it be? Think big but also think smal1. 4.. Some of your goals can involve improving the weaknesses you listed. Then you’ll have one reason fewer to doubt yourself.
● Look your best. Taking a little time to make yourself look good will help you have a positive attitude.
● Stand up straight, smile and look people in the eye. 5..
Having confidence in yourself takes some effort, but it brings great benefits.
A.Know yourself
B.Professional performance
C.It’s difficult to build up confidence
D.That makes it easier to make a good impression
E.Write down the problems you often come across in school life
F.Even getting something small done will give you confidence to achieve more goals
G.Act confidently, it won’t be long before your feelings follow the three kinds of behaviors
Exposing living tissue to subfreezing temperatures for long can cause permanent damage. Microscopic ice crystals (结晶体) cut cells and seize moisture (潮气), making donor organs unsuitable for transplantation. Thus, organs can be made cold for only a few hours ahead of a procedure. But a set of lasting new antifreeze compounds (化合物)—similar to those found in particularly hardy (耐寒的) animals—could lengthen organs’ shelf life.
Scientists at the University of Warwick in England were inspired by proteins in some species of Arctic fish, wood frogs and other organisms that prevent blood from freezing, allowing them to flourish in extreme cold. Previous research had shown these natural antifreeze molecules (分子) could preserve rat hearts at -1.3 degrees Celsius for up to 24 hours. But these proteins are expensive to extract (提取) and highly poisonous to some species. “For a long time everyone assumed you had to make synthetic (人造的) alternatives that looked exactly like antifreeze proteins to solve this problem, ”says Matthew Gibson, a chemist at Warwick who co-authored the new research. “But we found that you can design new molecules that function like antifreeze proteins but do not necessarily look like them. ”
Most natural antifreeze molecules have a mixture of regions that either attract or repel water. Scientists do not know exactly how this process prevents ice crystal formation, but Gibson thinks it might throw water molecules into push-pull chaos that prevents them from tuning into ice. To copy this mechanism, he and his colleagues synthesized spiral-shaped molecules that were mostly water-repellent—but had iron atoms at their centers that made them hydrophilic, or water-loving. The resulting compounds were surprisingly effective at stopping ice crystals from forming. Some were also harmless to the roundworm Caenorhabditis elegans, indicating they might be safe for other animals.
“These compounds are really cool because they are not proteins—they are other types of molecules that nonetheless can do at least part of what natural antifreeze proteins do, ”says Clara do Amaral, a biologist at Mount St. Joseph University, who was not involved in the research. Gibson’s antifreeze compounds will still need to be tested in humans, however, and may be only part of a solution. “We don’t have the whole picture yet, ”do Amaral adds. “It’s not just one magical compound that helps freeze-tolerant organisms survive. It’s a whole suite of adaptations.

Having an older brother comes with plenty of benefits. Big brothers tend to look out for their younger siblings(兄弟姐妹）,and despite the occasional rocky moment here and there, many siblings enjoy life-long close relationships. However, a new study finds an interesting downside: children with older brothers take longer when it comes to developing language skills.
The study, conducted by a group of researchers in Paris, France, builds upon earlier research that had already established that having older siblings is associated with poor linguistic(语言的）development. Now, researchers say they have come to a more specific conclusion: only children with an older brother exhibit these linguistic difficulties.
One would assume that children with older brothers would grow up around more conversation on a daily basis, thus speeding up their language development. Yet researchers say such children actually take longer than their older brothers to begin developing these skills.
Researchers studied more than 1,000 children from birth to the age of five-and-a-half years old. Each child’s language skills were tested at ages 2,3,and 5.5,using tests specially designed to measure numerous aspects of language development such as vocabulary, syntax, and verbal reasoning.
What the research team discovered was significant: children with an older brother had, on average, a two-month delay in their language development compared to those with an older sister.
As far as explaining this phenomenon, researchers have proposed two hypotheses(假设).The first is that older sisters tend to talk more often than older brothers, which would compensate for parents potentially being less present than they were for their first child. The second hypothesis is that older sisters usually compete with their siblings less than older brothers for their parents’ attention.
As of now, the study’s authors say they can’t say for certain why children with older brothers have a harder time developing language skills. In the future they would like to investigate if culture or location affects the results of these studies.
1.What does the underlined word“downside”in paragraph 1 mean?
A.difficulty B.drawback C.mistake D.burden

A.Having older siblings will affect the younger one’s language development.
B.Many children prefer having brothers and sisters.
C.Older brothers may have something to do with the linguistic difficulties.

3.Why do children with older brothers experience the delay in language development?
A.Parents tend to focus more on the first child.
B.Older sisters are more caring than older brothers.
C.Older brothers always seek to get more attention from their parents.
D.Younger children are always ignored by their older brothers.
4.What will further research of the study focus on?
A.The reasons for children’s delay in language development.
B.Other aspects that may influence the outcomes of the study.
C.More assumptions to explain the phenomenon.
D.The effect of culture on children’s language learning.
In one of my favorite photographs of my mother, she's about 18 and very tall, with long, blond hair. It's the 1970s and my dad is there, too, hugging her from behind．
I haven't seen this photo for years. I have no idea where it is now, but I still think of it and, specifically, my mom is in it. She looks so young and innocent. At that time she hasn't yet dropped out of college, or got married. The young woman in this photo has no idea that life will bring her five children and five grandchildren, one divorce, two marriages and a move across the country．
For me, as for many daughters, the time before my mother became a mother is a string of stories, told and retold: the time she sold her childhood Barbie doll to buy a ticket to Woodstock; the time she worked as a waitress at Howard Johnson's, struggling to pay her way through her first year at Rutgers. The old photos of her are even more appealing than the stories because they're a historical record, carrying the weight of fact．
It is always a comfort from those photos to know that time, aging and motherhood cannot take away a woman's essential identity. For daughters who closely resemble their moms, it must be an even bigger comfort: these mothers and daughters are twins, separated by a generation ,and an old photo serves as a kind of mirror．
For daughters, these old photos of our mothers feel like both a chasm(巨大差异)and a bridge. The woman in the picture is someone other than the woman we know. She is also exactly the person in the photo-still, right now. Finally, we see that the woman we've come to think of as Mom-whether she's nurturing(养育), or disapproving, or thoughtful, or supportive, or sentimental--is also a mysterious, fun, brave babe．
She's been here all this time.
