“Hi, Mrs. Grady,” said Mark when their neighbor opened her door. “Would you like us to shovel（铲） your sidewalk and driveway?” Shoveling was Jamie's idea, a way to earn enough money for the new Ocean Kingdom video game that came out the next day.

    Mrs. Grady was happy, “That would be wonderful, boys. I think the job is getting to be too much for me.”

“It will cost 10 dollars,” Jamie said. “If that's OK,” Mark added.

“Oh dear,” Mrs. Grady said disappointedly, “I haven't been able to get to the bank. I can offer homemade cookies, but I realize that's not what you had in mind.”

Mark was going to say that Mrs. Grady could pay them another time, but Jamie cut him off. “We'll come back later.”

Mrs. Grady doesn't look like the person who'd come to Mark's rescue last summer when Mr. Dunn's dog Goldie had just wanted to play, but Mark didn't feel comfortable around big dogs. He wanted to call for help, but his tongue seemed locked behind his teeth. Then Mrs. Grady's front door had flown open. She must have seen him from across the street. “Hold on, Mark. I'm coming!” “Goldie” she'd called. As soon as Goldie had turned her head, Mrs. Grady had slipped between Mark and the dog. She wasn't much taller than Mark, but she'd stood firm as a rock in front of him. “Goldie, go home!” Then she'd swept her broom to hurry the dog along. “Get!” Goldie had obeyed.

When Mark showed thanks to Mrs. Grady, Mrs. Grady laughed. “It was nothing. Good neighbors watch out for each other, don't they?”

And now Mrs. Grady needed Mark as much as he'd needed her last summer. He smiled and waved at Mrs. Grady, then his shovel deep into the snow.

“Hey!” Jamie shouted. “What are you doing?” Mark couldn't explain about Goldie and watching out for neighbors. “I like Mrs. Grady's cookies,” he said.

    In box-office terms, Steven Spielberg is the most successful movie director in the world. Jaws, E.T. the Extra-Terrestrial, Indiana Jones, Schindler's List ... his movies are cinema classics.

Q: What were you afraid of when you were a child?

A: I was my own monster (怪物). My fancy was unbelievable, so I was afraid of everything. A chair could very quickly change into a mouse. I remember looking up at the sky when I was five. One of the clouds up there looked like a beautiful bird, then suddenly it was a tiger. I ran home crying.

Q: What did your parents feel about that?

A: For my parents my imagination was a real problem, so much so that they seriously considered having me examined by a doctor. After all I was always seeing things that didn't exist (存在) except in my head. My mother and father thought I had something wrong with my mind. I probably did — but it is the gateway to a great career!

Q: What do you consider your greatest career achievement so far?

A: The right to decide my own programs. That was always my only dream, telling my stories without anyone else interfering (干预). It was also why I built my own company.

Q: Which movie did you enjoy making most?

A: That was E.T. the Extra-Terrestrial, because it was the first time I realized I wanted to be a father. Three years later I had my first son.

Q: Do you make home movies?

A: Yes, I always have a video camera with me. At Christmas it's traditional for my family to see a movie about the family that lasts one hour. We all watch the film together and everyone gets a DVD of it.

    On Thursday night my two adult children took us out to dinner as our daughter lives in Bathurst and she will be there for Father's Day with her husband's side of the family. Two of our grandchildren were able to join us.

    Having pre-celebrated my Father's Day and it being on our minds, my wife asked this question only this morning:

    "Do you remember anything about your father?"

    While this subject had come up before, however, the question had not been put so bluntly(直率的). I answered "No. My only memory is of the few photos outside." You see, my father died when I was only four years old.

    Many people have lost their father early in life and it is easy to feel somewhat sorry for having to deal with such a situation, especially when the death has occurred when you are at an early age. On reflection, I think I do not remember anything because he passed away when he was a member of the Royal Australian Air Force. He was a Corporal(下士) doing land based duties, however, a medical condition took his life. It was 1942.

    The 2nd World War was in full battle and Australia was being attacked. My Mum and I with my younger brother, were living with my grandparents and I can only imagine the emotional circumstances that existed in the household at that time. Probably not something that would leave a memory.

    What I would like to say at this time, as the question is often asked, "What did you learn from your father?" The thing I learnt from his passing, at the age of 28, is a love of life. What I do remember is growing up wondering if I would live to his age, and after I did, thinking each year the bonus(津贴) of life I had been blessed with when compared to my father.

    I have sometimes felt disappointment in not knowing my father but life has moved on. However, can I say to those who do have fathers, celebrate today with him and return him all the love and happiness he has given to you.

    A thrilling polar competition between two adventurers to cross Antarctica alone, unsupported and unassisted had a happy ending with both explorers achieving the unprecedented feat (功绩). American professional athlete Colin O'Brady and British Army Captain Louis Rudd set off a mile apart at the same time on November 3, 2018, from the Atlantic coast with the aim to become the first person to ski across the remote continent alone.

    Louis Rudd maintained the lead at first. However, O'Brady caught up with Rudd on November10 and never let the British man get close to him again. O'Brady was the first to conquer the 930 mile icy land, arriving at the Ross Ice Shelf on the Pacific coast by way of the South Pole on December 26, 2018. The 33-year-old spent 54 days skiing the world's coldest continent while pulling a 300-pound sled(雪橇) with supplies.

    Instead of leaving the harsh environment after completing the historic adventure, the explorer set up a tent on the world's largest ice sheet and waited patiently for Rudd to complete the great undertaking. On December 29, just three days after O'Brady arrived, the British explorer finished his adventure, becoming the world's second person to complete the solo crossing of the frozen continent.

Rudd was not disappointed at being second since he never considered it to be a     "race". Besides, the 49-year-old British Army Captain had a more selfless motive for attempting the feat. He was doing it in memory of his friend Henry Worsley, who had introduced him to polar exploration. The disaster happened while Worsley was trying to cross the continent alone in 2016. Rudd said, "I didn't want to get drawn into a race. All that mattered to me was that I completed it, and that I skied solo and unsupported, carrying the flag with Henry's name on it."

    After spending a few days camping 10 feet away from each other, the two adventurers were picked up by a helicopter to the South Pole scientific research station.

Land of fire and ice: Iceland

    Join an unforgettable tour of Iceland's splendid landscapes, timed to arrange four days filled with volcanic and geological adventure, and evening opportunities to see the Aurora Borealis.

    Day 1: Vatnajokull Glacier (冰川)

    Today you'll take a walk on Europe's biggest ice cap-Vatnajokull-which has around 30 glaciers flowing out from it. No experience is necessary to take part in the hike. It's discouraging to think that the glacier is retreating due to rising world temperatures, and in future years the glacier may be gone. If you prefer a relaxing morning you can explore the surroundings of the farm stay and head to the Thorbergur Centre.

    Day 2: Secret lagoon (泻湖) and Reykjavik

    This morning we make our way to the Lava Centre which is an interactive, high-tech educational exhibition describing volcanic activity, earthquakes and the creation of Iceland over millions of years. After our visit, we will continue to the Secret Lagoon natural hot springs, located in the small village called Fludir, giving you the opportunity to relax in the warm waters before travelling to Reykjavik.

    Day 3: Reykjanes peninsula (半岛)

    Head out to the Reykjanes Peninsula. It is a land-born highly volcanic counterpart of the Mid-Atlantic Spreading Ridge where two tectonic plates part at an average rate of 2.0-2.5 cm/yr. Four volcanic systems and fissure (裂缝) groups line the peninsula from SW to NE. They contain open fissures, normal faults, high-temperature fields and volcanic fissures.

    Day 4: Depart Reykjavik

    Today is departure day and time to say "sjaumst". Your group departure transfer will take you to the airport for your flight home.

Every four or five years, vast quantities of warm water build up along the west coast of South America. This phenomenon, El Nino, creates storms that cause destructive floods. The result is costly.

Modern farmers come to terms with El Nino. They use money saved in good years to rebuild in bad ones. But history suggests it need not be like that. In a paper published recently, Ari Caramanica, an archaeologist at University of the Pacific, in Lima, shows how it used to be done. And the answer seems to be, "better".

Dr Caramanica and her colleagues have been studying the Pampa de Mocan, a coastal desert plain in northern Peru. Pampa de Mocan is not suitable for farming. Its soil contains little organic matter and the annual rainfall in non-Nino years is usually less than two centimeters. Today's farmers therefore depend on canals to carry water from local rivers to their fields.

It had been assumed that ancient farmers had a similar arrangement — and so they did. But Dr Caramanica also found eight canals that could carry water far beyond the range of modern farms. She thinks that they were intended to guide the floodwaters arriving during Nino years. Around a quarter of the ancient agricultural infrastructure of this area seems to have been built only for managing Nino-generated floodwaters.

Evidence from pollen supports this theory, revealing that Pampa de Mocan produced lots of crops in some years, while remaining nearly barren in others. The team also uncovered two cisterns in the area serviced by the extended canals. These, probably, were used to store extra flood-water.

These findings suggest that, rather than resisting El Nino, early farmers in Pampa de Mocan were ready to make use of it when it arrived. Modern farmers might do well to learn from them.
