New Orleans, Louisiana, was established as part of the French Empire in 1718.

    Its location on the east bank of the Mississippi River gave it control of the American hinerland and it became strategically important to many nations. It was transferred from France to Spain, returned to France, and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it, and the Americans under General Andrew Jackson.

    The riverbed of the Mississippi is constantly silting（淤积）and the river is now actually higher than the city. Levees hold back the river and giant pumps are used to move water from the city into the river.

    Although New Orleans has been a part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which, for many years, was its only law.

    New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The Jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting surface of yesteryear is a busy industrial and port city. Grain and coal come from the Midwest and foreign goods are unloaded here. New Orleans is no longer a sleepy Southern town—but it's still fun to visit.

To whom it may concern,

    My husband Jim and I got married in 1965. For the first ten years of our marriage, I was very happy to stay home and raise our three children. Then about four years ago, our youngest child went to school, and I thought I might go back to work.

    Jim was very supportive and helped me to make my decision. He started to do all the things I used to do around the house, and said he thought I could be a great success in business.

After several weeks of job hunting, I found my present job, which is working for a small public relation firm. At first, my husband was proud of me and would tell his friends, "My clever little wife can run that company she's working for."

    But, as his joking words were becoming reality, Jim stopped talking to me about my job. I have received several promotions and pay increases, and I am now making more money than he is. I can buy my own clothes and a new car. Because of our combined incomes, Jim can do things that we had always dreamed of doing, but we don't do these things because he is unhappy.

    We fought about little things, and Jim is very critical of me in front of our friends. For the first time in our marriage, I think there is a possibility that our marriage may come to an end.

    I love Jim very much, and I don't want him to feel inferior(较差的), but I also love my job. I think I can be a good wife and a working woman, but I don't know how. Can you give me some advice? Will I have to choose one or the other or can I keep both my husband and my new career?

    Please help.

Yours,

Mary

    Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.

    "Our findings suggest that there is something about actively falling snow that causes wolves to slow down," said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. "We don't know the exact mechanism behind that. It's unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation（降雪量）might affect wolves' hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey."

    Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry（测距仪） data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.

    With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.

    "Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources," said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.

    "Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios（设想）but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes."

When we hold our breath and go underwater, we'll soon be unable to stand it. {#blank#}1{#/blank#} However, there's little chance of catching up with the Sama-Bajau, who can stay underwater with a single breath for quite a long time. 

Sama-Bajau is a collective term（集合术语）that refers to several closely related native peoples. The Bajau live on long houseboats or small wooden houses that are built on the sea, close to the shore in Southeast Asia. {#blank#}2{#/blank#}

 As they make their living primarily from fishing, they have become exper t free divers（自由潜水者）. Bajau divers have the longest daily diving time without breathing among allhumans. {#blank#}3{#/blank#} In their free time, the kids help around the house or play on the beach. 

It appears that centuries of free diving have scientifically distinguished the Sama-Bajau. According to research, the Bajau's spleens（脾脏）are much larger than the average people's on land. {#blank#}4{#/blank#} Besides, the Bajau have also developed excellent underwater vision. 

{#blank#}5{#/blank#} The main cause is massive fishing, which has made it increasingly difficult for the Bajau to make a living and rely on fishing alone. As a consequence, more and more people are leaving the seas, and apparently, it's only a matter of time before the Bajau and their amazing qualities disappear. 

A. Larger spleens can have some weaknesses. 

B. Therefore, many older divers are hard of hearing. 

C. The difference makes the Bajau quite able to dive underwater. 

D. They only go ashore to trade or seek shelter during sea storms. 

E. Bajau children master swimming and diving skills at an early age. 

F. The existence of this special group of people is threatened nowadays. 

G. With free diving training, we can increase the time underwater by a few minutes. 

Standing on the South Pole at the start of the year with the wind blowing across the Antarctic, travel blogger Johnny Ward felt a wave of relief.

Just a week before, in early January 2024, he'd struggled through snow and ice to climb to the top of the Vinson Massif, Antarctica's highest peak. Years before, in 2017, he'd become the first Irish person to visit every country in the world.

Now, after decades of traveling and mountaineering, Ward could claim another world first—the Ultimate Explorer's Grand Slam (大满贯), which involves reaching the highest peak on every continent, and visiting both the North and South Poles in addition to visiting every country.

"I feel relieved," Ward recalled as he slowly made his way back to his home in Thailand after climbing to the top of the Vinson Massif and then setting foot on the South Pole. "But also I'm aware I'm a normal guy, not a world-class athlete, so I guess it was more about resilience and determination more than any ability. Although I met with lots of barriers, I overcame them one by one."

Ward had previously devoted a decade of his life, between 2007 and 2017, to visiting every country in the world. The incredible journey saw him hitchhike (搭便车) a ride on a container ship from Oman to Socotra in Yemen, travel overland from Cairo to Cape Town and travel from South Korea to Australia by bus and boat.

"It had been a huge life goal, over a decade of my life, and then when I finished that I was aimless and had no idea what to do next," he said. "I started eating badly, drinking too much, putting on weight and I ignored my business."

Ward decided that the best way to overcome this was to challenge himself again. He began running ultramarathons (超级马拉松) and climbing mountains, and soon found that with extreme purpose and direction, he was back to loving life again.

So where will Ward go next? Space? The bottom of the Mariana Trench, the deepest point of the ocean? "All good things come after suffering, and I want to share that with people. So that's the next plan," he said.
