It is natural that children are curious about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry.
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.According to the passage, which of the following statements is true?

John Blanchard was studying the crowd making their way through the station. He was looking for the girl whose heart he knew, but whose face he didn't, the girl with the rose.
When reading a book in a Florida library a year before, John became interested not in the contents of the book, but in the notes penciled in the margin. The handwriting reflected a thoughtful soul and beautiful mind. He discovered the former owner's name in the front of the book: Miss Hollis Maynell.
He located her address and wrote a letter introducing himself. The next day he was shipped overseas to serve in the army. During the next year, they grew to know each other through the mail and their friendship developed. John requested a photograph, but she refused, saying if he really cared, it wouldn't matter what she looked like. When the day finally came for him to return home, their first meeting was suggested — 7:00 p.m. at the Grand Central Station in New York.
She wrote, “You’ll recognize me by the red rose I wear on my coat.” So now John was in the station to meet the girl with a rose.
As a pretty and slim girl in green came over, John noticed her blue eyes like flowers in spring. He walked directly towards her, entirely forgetting she was not wearing a rose. As John came closer to her, he saw another woman with a red rose stood nearby. Well past 40, this woman had graying hair done under a worn hat. Seeing the girl in green walk quickly away, John felt as if he were split in two. He desired to follow that girl, but longed for the woman whose spirit had truly companioned and supported him.
The woman looked gentle and sensible. John went to her, saying, “I’m Captain John Blanchard. You must be Miss Maynell. I am glad to meet you here. May I take you to dinner?”
She replied with a smile, “I don’t know what this is about. But the lady in green who just went by, begged me to wear this rose on my coat. She said if you asked me out to dinner, I’d tell you she is waiting for you in the big restaurant across the street.

READY or not, the college application season has begun. There are two main kinds of early admissions programs: Early Action and Early Decision.
Early Action is a great choice for the well-prepared student. Students apply early, and are allowed to apply under an Early Action program to as many colleges as they choose. The biggest advantage for students is that colleges let them know early – in most cases, before Jan 1. Roughly 15 percent of colleges and universities offer an Early Action option. Oct 15 is now the first deadline for many colleges and universities.This movement toward earlier deadlines is especially popular in the Southeast, with many of the large public universities leading the way. North Carolina State University, the University of South Carolina and the University of Georgia all have an Oct 15 Early Action deadline.
Early Decision is a promise that cannot be reversed. Students who are accepted must take back their other applications and should attend that school. Students are allowed to apply to just one school under an Early Decision program. Early Decision deadlines are in early November, with colleges letting students know by mid-December.Many students believe that they are more likely to be accepted if they apply for Early Decision, but it actually depends.
In some cases there is big increase in students being accepted, and at other colleges it is not that big at all. Generally, the strongest students are applying early. Athletes and students with focused interests are encouraged to apply for Early Decision

OF course, Ms Cratty wasn’t really my aunt and, out of fear, I never called her that to her face. I only called her “My Aunt Fannie (俚语)” because the name always made my father chuckle (轻声地笑) and caused my mother to look seriously at both of us – at me for being disrespectful of my elder, and at my father for encouraging my bad behavior. I enjoyed both reactions so I looked for every opportunity to work the name into as many conversations as possible.
As a young woman, my mother had worked in the kitchen of a large farmhouse owned by Ms Cratty and her twin brother. Neither had married, and they had no children. My father once told me that it was because they were both too mean to share their family’s money or pass it on. Ms Cratty was famous for her jam and for never sharing the recipe with another one. Even though my mother knew the recipe , she never made the jam without Ms Cratty kitchen to direct the process and keep the secret.
Each August, my mother would prepare me for Aunt Fannie’s visit. One year, after I had been particularly helpful with the jam process Aunt Fannie gave me a quarter and then made me promise that I would never spend it. “Hold onto this quarter,” she said, “and someday you will be rich. I still have my very first quarter, given to me by my grandfather.” It had obviously worked for her. So, I put the quarter in my dresser drawer, and waited to become rich.
I now have the jam recipe and the quarter from Aunt Fannie. Neither has made me wealthy, but I keep them as reminders to hold onto the valuable things in life. Money can make you feel rich for a while, but it is the relationships and the memories of time spent with friends and family that truly leave you wealthy. And that is a fortune that anyone can build.
| A．Because she wanted to show respect for her. |
| B．Because she believed that made her seem closer to her. |

| A．owned the large farmhouse with Aunt Fannie |
| B．disliked Aunt Fannie’s meanness and the way she would never share |
| C．didn’t know the exact way to make the jam |
| D．tried to make Aunt Fannie believe that the secret recipe was safe |
| A．was a reminder of the valuable things in her life |
| B．would bring her good luck and make her rich |
| C．was a small reward for her help with the jam process |
| D．was the exact one that Aunt Fannie had received from her grandfather |
| A．have a certain secret recipe |
| B．have lasting love and friendship |
| C．share our wealth with others |
| D．have good fortune and money |
HOW many of you have used rock, paper, scissors (RPS) as a “fair” way to settle something? If you think it is a game of chance, think again, according to scientists.
RPS is a game as popular in the East as it is in the West. The rules are the same: Two players make one of the three hand signs. To decide the winner, rock breaks scissors, scissors cut paper, and paper covers rock.
Many of us play with no game plan in mind. But researchers have worked out several winning patterns. The World Rock Paper Scissors Society holds tournaments (联赛) in Toronto, Canada. According to their data, players choose rock (35.4 percent) and paper (35 percent) more than scissors (29.6 percent).
If your opponent is a man or an angry person, it’s quite possible they will start the game with rock, researchers have found. If your opponent is a woman or a beginner, you should expect them to start with scissors.
Earlier this year, Chinese scientists asked 360 students to compete in a RPS tournament at Zhejiang University. Scientists found that winners tend to choose the same action they won with, while the loser tends to change to the next action in the order of rock, scissors, paper.This is called the “win-stay lose-change” strategy(策略). Humans use this strategy in many competitive situations.
Expert RPS players have many other techniques. Monica Martinez, 2008 winner of the World RPS Tournament, said that she read faces.“I didn’t worry about what I was going to do, I just did what I thought they were going to do,” she told The Telegraph. If your friends are similar experts, learn from Jonathan Monaco, winner of the 2009 USA RPS Tournament. He wears dark sunglasses to cover his expressions during the game.
Remember, the strategy for playing RPS depends on how skilled your opponent is. But if you’re looking for a quick, simple winning rule for a match, choose paper. Scissors is the least popular choice, and men favor rock. Both are reasons to choose paper.

| C．beginners have barely any chance of winning against skilled RPS players |
| D．men are usually better at RPS games than women |
I have happy memories of trips to Europe, but my trip to Romania was unique. My husband was born there, but his family sent him to study in Italy. He hasn’t seen his family since he was 16.
When we reached Bucharest, his family was waiting outside to greet us. After a lot of hugging, kissing, and crying, his family also embraced (拥抱) me, the American wife with two young children. They had great interest in me. Few Americans visited Romania at that time, and most Romanians had little chance to travel.His family loved our gifts. We made trips to the Black Sea and the Carpathian Mountains. Eating at outdoor cafes to the sound of gypsy violins was very different, but nothing was as unforgettable as family dinners.
Most Romanian homes had old-fashioned washing machines but no dryers. It was a hot summer. My husband’s relatives didn’t want to risk dirtying their clothes. Their solution was as simple as it was surprising: The women had dinner in their bras (文胸) and slips (衬裙). The men were shirtless. They all had jobs, so time was precious. Disrobing (脱去衣服) for dinner was a small inconvenience compared with the effort of doing laundry – at least in their household, and perhaps all across Romania. I washed my clothes by hand and hung them outdoors to dry. I, of course, having just met them, ate fully clothed.
On the last night of our three-week stay, we had a large family dinner. I was tired of washing my clothes. So I pulled my dress over my head and placed it on the chair behind me. The table applauded. Even with my poor Romanian, I understood that they were saying: “She’s part of our family now.”

| B．she intended to talk to his family in English |
| C．she got extra attention from his family for her nationality |

| A．Most of his family members didn’t travel a lot at the time. |
| B．Women in his family had dinner in only their underclothes. |
| C．Most of her husband’s relatives didn’t like doing laundry. |
| D．They had old-fashioned washing machines but no dryers at home. |
| A．the author disrobed for dinner as the family did |
| B．they just wanted to show their love for the author |
| C．the author could finally understand them easily |
| D．it was time for the author to give a speech |
