Getting old might not be something that's yet to cross your mind. But ageing is unavoidably going to get the better of us one day. And that’s why scientists are constantly seeking out evidence that will show us what we need to do to achieve longevity.
We all know that regular exercise is good for us. In recent years, although we've been told to aim to walk 10,000 steps a day to remain healthy, other advice to do three quick and energetic 10-minute walks a day is thought to be even more effective. And the latest piece of research might put a spring in your step if you’re someone who walks at a fast pace. That’s because, according to scientists, the speed at which people walk in their 40s is a sign of how much their brains, as well as their bodies, are ageing.
Tests on 1,000 people from New Zealand born in the 1970s found that slower walkers tended to show signs of "accelerated ageing". Their lungs, teeth and immune systems were in worse shape than those who walked fester. And what’s worse, the study found not only did slower walkers' bodies age more quickly, their faces looked older and they had smaller brains.
This might be seen as a wake-up call for people with a slower pace who might feel it's time to work out get fitter. But it might be too late; researchers say they were able to predict the walking speed of 45-year-olds using the results of intelligence, language and motor skills tests from when they were aged three. They also suggest that even in early life, there are signs showing which people will go on to have a healthier life.
So, what's the point of knowing that a slower walking pace might mean a smaller brain? Well, researchers say measuring walking speed at a younger age, and understanding what this might mean, could be a way of testing treatments to slow human ageing. This might help us make lifestyle changes while we're still young and healthy. Any steps we can take to prolong a good mental and physical state is a no brainer!

In January 2020, as I watched the news about the coronavirus outbreak in Wuhan, I kept thinking, “This is not good.” As the situation stepped up, I knew it was only a matter of time before it came to my hometown in Cornwall. And, on February 15, it did.
That day, we found out the government was sending over 100 Canadians citizens who were aboard the Diamond Princess, an infected cruise ship, to a hotel here for a 14-day quarantine. Suddenly, things got very real. As a nurse in the emergency department at Cornwall Community Hospital, I’d be treating any passengers with the virus. I didn't even have time to fully absorb the news—I just grabbed my scrubs (手术衣)and sprang into action.
There are times when it feels like the whole department is on fire. There are moments when we have multiple critical patients hanging in the balance, incoming trauma (创伤)patients, and an overflowing waiting room. After all, in the ER (emergency room), we're still treating car accident injuries, heart attacks, strokes—anything you can think of, and a dozen things you can't. And it's all complicated by this virus.
I’ve been a nurse since 1994, so I’ve helped prepare for my fair share of outbreaks. I've worked through the rise of Ebola, H1N1, and SARS. But COVID-19 is a sneaky virus. This outbreak is scarier because patients can spread the virus while symptom-free. With SARS, it was clearer who was infected. With COVID-19, we have fewer clues that someone might be a carrier.
I felt so bad for the first cruise ship patients we treated—we were the first people they'd seen in a while, and our equipment made us look like aliens? But they were very kind and patient. They were just eager to get home. Luckily, they didn't have the virus. In the end, we prevented disaster.
I don't think we've yet seen the full extent of this situation. However, I believe my hospital will get through this and we will eventually win the battle.

Canada is a land filled with fascinating places and amazing adventures. The only problem: Narrowing down your choice of destinations. Here are several of the best places to visit in Canada for any traveler determined to discover the true north.
Churchill, Manitoba
Set on the shores of Hudson Bay, this subarctic（靠近北极的）town has earned international fame as the polar bear capital of the world. So plentiful are the bears that the town actually has a “polar bear prison,” which holds bears that are resistant to people's instruction and wander into town until they can be released back into the wild. Encountering a polar bear in the wild is no doubt an unforgettable experience.
Banff and Lake Louise, Alberta
Set inside the borders of the vast Banff National Park, Banff and Lake Louise is one of the best places to visit in Canada. Here you'll find a Rocky Mountain wonderland; a place of electric blue glacial lakes, waterfalls, and abundant wildlife (from elk to bighorn sheep). Stay either in Banff, the busy center of the area and home to classic hotels like the Fairmont Banff Springs (one of Canada's greatest hotels), or hike trails up into the mountains—and unparalleled(无与伦比的)silence-are just steps away.
Bay of Fundy, New Brunswick
Recently shortlisted in a massive international competition to name a new seven wonders of the natural world, the tides on this big bay, make it truly one of the best places to visit in Canada. The most extreme tides on earth, they rise and fall more than 50 feet in some places. These can be seen most dramatically at a place like Hopewell Rocks, unique stone formations that, at low tide, form towers on dry land but become islands as the water rises.
Quebec City
The oldest walled city in North America, Quebec City holds both British charm and culture alongside its unmistakable French-Canadian character. It also bears the distinction of being the place where, as every good Canadian history student knows, Wolfe defeated Montcalm on the Plains of Abraham, securing Canada for the British Empire.
1.Why are the polar bears put into prison in Churchill?
A.Because there are a large number of bears.
B.Because the government wants to attract more tourists.
C.Because they don't follow people's guidance.
D.Because they resist living in town.
2.What can we learn from the passage?
A.When traveling in Canada, people have narrow choices of destinations.
B.You can enjoy neither busy life nor unparalleled silence in Banff and Lake Louise.
C.Hopewell Rocks stand like islands on dry land but turn into towers when the tide comes.
D.Britain and France once had a war to secure their own rule over Canada in Quebec City.
3.The author writes the text with the intention of .
A.showing the most worth-visiting country B.helping tourism boost in Canada
