The Arctic will soon be free from ice, experts say. The change is bound to take place, but the global warming and climate change are changing the earth’s landscape (地形) rapidly,causing panic worldwide.
Experts say that the Arctic sea ice is melting (融化) quite faster than expected and it can affect not just the region, but Earth in general. A scientist even says that next year, or maybe the year after that, the Arctic will be free of ice.
Peter Wadhams, a scientist, said that the melting trend led to his statement. “Most people expect this year will see a record low in the Arctic’s summer sea-ice cover. Next year or the year after that, I think it will be free of ice in summer and by that I mean the central Arctic will be ice-free,” Peter Wadhams, director of the Scott Polar Institute in Cambridge, said in an interview with the Guardian. “You will be able to cross over the North Pole by ship,” Peter Wadhams added. He strongly believes that although some pieces of ice will remain, the Arctic basin may be free of sea ice in the next two years starting in the summer of 2017.
Wadhams’ study says that melting sea ice will have a great influence on the planet since the sea ice is more capable of reflecting (反射) sunlight compared to water that can only reflect 10% of the sunlight. Once the sea ice melts, the water can only reflect a small amount of sunlight. This means that the Earth will receive and absorb more sunlight, making the planet even hotter.
The year 2016 has already broken records of the hottest temperature ever recorded and the trend doesn’t seem to show any decrease in global warming. “It doesn’t look like the ice is healing and growing back,” Tom Wagner, NASA’s manager for cryosphere (冰凍圈) research said in a statement.
Like Wadhams, scientists and researchers all over the world are lecturing around to educate people to help lighten global warming that has already changed the planet’s landscape.

When I was a kid, I always used to wonder how in the world my father worked outside in the winter without a coat. It could be minus 20 degrees centigrade and there’d be Dad, removing snow, or perhaps chopping(砍) some wood — his coat thrown aside — wearing a shirt, a cap, and a pair of gloves.
“Aren’t you cold, Dad?” I’d ask. “No,” Dad would reply. “I’m not cold—working too hard to be cold.”
Many times I wondered whether my father was an extremely tough man, or whether he was foolish.
One time when I was quite young, perhaps five or so, I went ice fishing with Dad. It was a bright, clear day—and bitterly cold.
After we’d been out on the ice for a little while, my feet started getting cold.
“Daddy, my feet are cold.” I said.
“Yeah, it’s cold out here today,” he replied.
“Tell you what,” he said. “Walk around. Make some circles in the snow. See how many different patterns you can make. That will get your feet warm.”
I was just a little girl at the time but I remember thinking, “How in the world will walking around in the snow make my feet warm? Dad must be out of mind.”
But he was my father, after all. I made circles in the snow. I made squares. Pretty soon I was having so much fun making patterns in the snow. I forgot about my feet being cold.
Now, all these years later, I know, too, from personal experience how my father was able to take his coat off and work outside in the winter wearing just a shirt, a cap and gloves. Because I do it, too. “Aren’t you cold?” my husband asked one winter day. “No,” I replied. “I’m not cold—working too hard to be cold.”
I hope my husband has decided I’m both tough and smart. But I guess quite a bit of the time he thinks I’m foolish.
Wherever Dad is on that great big farm in the sky—I’m sure he can’t help but smile whenever I take my coat off while I’m working outside in the winter.
1.When the author’s feet felt cold, her father advised her to ________.
A. go home alone firstB. keep walking in the snow
C. draw pictures in the snowD. light a fire on the ice
2.Hearing her father’s advice, the author thought her father ________.
A. forgettableB. warm-heartedC. crazyD. cruel
3.What might the author’s husband think of her?
A. Tough.B. Smart.C. Brave.D. Foolish.
4.The author’s purpose of writing this passage is to ________.
A. remember her tough and smart father
B. show how her father cared about her
C. describe memories of her childhood
D. explain why her father loved her so much

How to prepare for exam?
Here are some tips you can read with your child.
The first step in preparation for examination is to set a fixed time each day to study and a schedule to say when to start the revision and for which subject.The plan should include how many chapters to revise and how many worksheets to work on.1.

4. For lessons,pupils must participate in lessons and discussions actively.For exercise,work on the simple ones in the textbook.For theory,pupils can use the mind map method to summarize the facts.
At last,study smart.Focus on chapters that are the core of the subject or difficult chapters.5.
A.Next the most effective way to revise is to use an active approach.
B.Making good preparations counts.

My parents and I made a tour to Xi’an last summer holiday. Instead of having a travel agency arranging our transportation and accommodation, we booked the train tickets and hotel rooms on the Internet by us. During our tour in Xi’an, we went to many places of interests and took lots of photos, learned about the history of Xi’an. No tourists would miss the local food in Xi’an, so would we. We enjoyed the typically local food, it tasted more delicious than we had expected. Hardly had I returned than I shared the photos and experiences for my classmates. The trip to Xi’an has been such happy memory to me that I will never forget it.

There is no doubt whether setting a goal is very important. By set goals you are
taking control of your life. It is having a map to guide you to where you want to head.
With a clear direction, and with certain plans, you will straightly get what you want. On the contrary, without the goal, you do not know where to go or what you want. Then your life becomes dull or meaningless just like the dead water in a muddy lake.
We find that successful people were always those having and achieving their goal.
They set goals, short-term or long-run, to help realize our dreams. Therefore, from my point of view, we should make clear what we really want it and follow our plans as many winners do.

One evening last fall, while Marcos Ugarte did his homework and his father, Eduardo, a teacher, prepared lesson plans, they heard shouting outside. Eduardo, 47, and Marcos, 15, stepped onto the balcony(陽(yáng)臺(tái)) of their two-story home. Immediately, Marcos’ s eye was caught by a flame from one of their neighbors’ houses.
"Dad, the house is on fire!" Marcos cried. Dressed only in shorts, the barefoot teen
dashed towards the Mas’ home with his dad. Grandmother Yim Ma, mother Suzanne Ma, and son Nathan Ma were gathered on the front grassland shouting for help. When the Ugartes got there, they saw through the open front door that father Alex Ma was falling down the stairs, coughing, his face black with dirt.
"Is anyone else in the house?" Eduardo asked.
"My son!" Alex managed to say, pointing to the second floor.
Eduardo started up the stairs, but thick, black smoke, swirling ash, and extreme heat forced him to his knees. He inched upstairs and down the hall where Alex said he would find Cody, eight, who had locked himself in a bedroom. "I’d never seen smoke like that," says Eduardo. "My glasses immediately turned black from the ash."
As the fire spread across the hall, Eduardo banged on the bedroom door and tried to turn the handle. But Cody didn’t respond, and Eduardo made his way back downstairs. At the same time, Marcos saw Yim and Suzanne pulling an aluminum(鋁) ladder out of the garage. "Cody was standing at the window, screaming for help," says Marcos.
"I knew I had to do something." He grabbed the ladder, positioned it near the window, and climbed towards the boy. When Marcos reached the window, he pushed the screen into the room and persuaded Cody out. "It’s OK," Marcos told him. "I’ve got you." Holding Cody with one arm, Marcos moved down the ladder. Halfway down, he handed the boy to a neighbor.
The day after the fire, Alex visited Marcos. "Thank you for saving my son," Alex said. "You are his hero forever."

When I was watching a sports event yesterday, I met with an amazing sight. It was not a gold medal, or a world record broken, but a show of pure courage and determination.
The event was swimming. I watched a man dive off the blocks and knew right away that something was wrong. I'm not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold — his arms were waving in an attempt at freestyle.
I heard the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes (劃水) and you could tell he was worn out. But in those few awkward strokes, the crowd changed. No longer were they laughing, but beginning to cheer. Some even began to stand and yell things like, "Come on, you can do it!" He did. The crowd went wild.
Just a short year ago, he had never even swum, let alone race. His country had been invited to take part in the event. Even though he recorded the slowest time, this man gave more heart than any of the other competitors—a man that gave his all, knowing that he had no chance but to compete because of the spirit of the games.
1.We know from the passage that the swimmer ________.
A. was not professional
B. had two competitors
C. had a wrong start
D. didn't try his best
2.What can be learned from the last two paragraphs?
A. The swimmer lost his spirit.
B. The swimmer didn't finish his match.
C. The audience was touched deeply by the swimmer.
D. The crowd supported the swimmer from the beginning.
3.The author's attitude towards the swimmer is that of ________.
A. tolerance
B. disappointment
C. carelessness
D. admiration
4.Which one is the best title of the story?
A. Successful Swimmers
B. Go for it
C. What an Event
D. Awkward Strokes

Today’s demands for measuring childhood success have chased household chores from the to-do lists of many young people. In a survey of 1,001 US adults released by Braun Research, 82% reported having regular chores growing up, but only 28% said that they require their own children to do them. “Parents today want their kids spending time on things that can bring them success, but ironically, we’ve stopped doing one thing that’s actually been a proven predictor of success—and that’s household chores.” says Richard Rende, a developmental psychologist.
Giving children household chores at an early age helps to build a lasting sense of mastery, responsibility and independence, according to research by Marty Rossmann, professor at the University of Minnesota. In 2002, Dr. Rossmann analyzed data from a longitudinal(縱向的) study that followed 84 children across four periods. She found that young adults who began chores at ages 3 and 4 were more likely to have good relationships with family and friends and to achieve academic and early career success, as compared with those who didn’t have chores or who started them as teens.
Chores also teach children how to be empathetic(感同身受的) and responsive to others’ needs, notes psychologist Richard Weissbourd. In research, his team surveyed 10,000 high-school students and asked them to rank what they treasured more: achievement, happiness or caring for others. Almost 80% chose either achievement or happiness over caring for others. As he points out, however, research suggests that personal happiness comes most reliably not from high achievement but from strong relationships. “We’re out of balance,” says Dr. Weissbourd. A good way to start re-adjusting priorities(優(yōu)先事項(xiàng)), he suggests, is by learning to be kind and helpful at home.
The next time that your child asks to skip chores to do homework, resist the urge to let him or her off the hook. Being slack(懈怠的) about chores when they compete with school sends your child the message that grades and achievement are more important than caring about others. What may seem like small messages in the moment but add up to big ones over time.
1.What can we learn from the first paragraph?
A. Parents today have recognized the importance of chores.
B. Most parents today think chores are necessary for measuring kids’ success.
C. Most adults require their children to do regular chores now.
D. Doing regular chores can help children to succeed.
2.What can we conclude from Rossmann’s longitudinal study?
A. Children will not achieve academic and career success with few chores.
B. It makes little difference when children begin chores.
C. Chores should be given to children at an early age.
D. Young adults beginning chores as teens are more likely to be responsible.
3.What do students value more according to Weissbourd’s survey?
A. Responding to others’ needs.
B. Achieving high achievements.
C. Practising kindness and giving help.
D. Building strong relationships
4.What can be the best title for the text?
A. Children need regular chores
B. Children need to be independent
C. Household chores build up relationships
D. Chores bring children responsibility
