2 . When water is cold, people will find it uncomfortable to swim. Wetsuits(潜水服）can help keep people warm.    1    So wetsuits are important. In many water sports, you can find people wearing them.

The wetsuit doesn't have a long history. According to studies, the wetsuit only began during WWII when Italians started wearing wetsuits that were made of rubber. And it was widely believed in 1951, Hugh Bradner began working to improve the equipment.     2    

Now there are many kinds of wetsuits. Contrary to what some may think, wetsuits do not work by keeping the diver(潜水员）dry; they are designed to let water into the suit. This thin layer of water is trapped（保存）between the diver and the suit. And it's allowed to move between the skin of the diver and the inside layer.     3    And it can help keep the diver comfortable during the diving process. That's why it's important to have a nice, tight fit for a wetsuit.

    4    The shorter wetsuit often provides cover for the main part of people's bodies. This kind of wetsuit works well with boating, water skiing, swimming, etc. A longer wetsuit can completely cover the body, including long legs.With more protection for the body, it may be used in cool weather conditions.

Wetsuits can also differ in thickness. They range from about 0. 5mm to 8mm in thickness. It's true that thicker wetsuits are more likely to affect your movement.     5    Generally, the colder the water you plan to dive in, the thicker the wetsuit should be.

3 . Ryder was born with a serious illness and has never been able to walk. When he started attending preschool, he had to be _______ to the end of the road in the _______ to wait for his school bus by his parents every day. As Ryder was unable to _______ for this bus if he was late like his schoolmates, he would have to wait for up to 15 minutes out in whatever _______ there was. Although his father had _______ a patio (露台) umbrella at the end of his driveway to provide some _______ from harsh weather, he still would get wet.

Then his father _______ for help on Facebook looking to see if someone might have an old bus hut (小屋). After the post, he was suggested to reach out to the _______ class at Westerly High School.

_______ , he sent an email to Dan McKena, who had been teaching construction technology at Westerly High School, asking if he’d be ________ in this kind of project. Delightfully, Dan ________ with an “absolutely” and then he worked hard on the hut with his students for weeks.

The hut made of wood was ________ enough to shelter both Ryder and one of his parents or a nurse comfortably and was finally ________ to the home six weeks later. Now, Ryder ________ it every day and his parents wait inside it every day while they await his returning home. He considers the hut ________ and does like to hang out in it from time to time.

5 . When I was growing up in Minnesota, Joe Versus the Volcano was one of my favorite movies. I ________ to be swept away to an island. But as I found myself in La Palma ________ on the Cumbre Vieja eruption in the Spanish Canary Islands, I quickly ________ that there’s nothing romantic about volcanoes or being trapped on an island.

I had come ________ — an N95 mask, baseball cap, and a swimming mask. But nothing could prepare me for the invasiveness of the volcanic ________ . It fell from the sky like a rainstorm, lining streets, ________ doorways and windowsills, and filling my ears.

It wasn’t long before the airlines canceled all flights. When ________ began panic, buying all the ferry tickets as I was interviewing residents about their futures, I realized I had ________ the boat.

For two days, I wandered ________ streets awaiting the resumption of travel, carrying a backpack and feeling progressively stuck and at times ________ . And then I realized I was being given the ________ for deeper insight. Here I was ________ what the local people were feeling: uncertainty, frustration, and tiredness from living next to an erupting volcano with no end in sight.

Like the people of La Palma, I ________ others to get me through — from the English woman who ________ me a bag of oranges from her garden to the minister of the church who let me use the bathroom after being trapped at the top of a mountain.

As I finally left, I realized how ________ I was to have experienced the humanity of the people in La Palma in the face of crisis. I know it’s what will pull them through it.

I’m not Chinese, but I love Chinese New Year. There are many fun New Year     1     (celebrate), but nothing quite matches the excitement of the lion dance which can wake up the spirit     2     (complete).

The sound of the drums,       3     you can feel throughout your entire body, is quite inspiring. The two performers are very flexible. But it is actually very difficult as the lion head is very heavy and being the     4     (low)part of the lion is tiring as he has to bend his back and also carry     5     person in front sometimes. The lion head is made with paper over a bamboo frame,       6     (cover)in gauze (纱布), and decorated with beautifully-colored materials.

The lion dance     7     (believe)to have first appeared in the Qianlong Emperor's dream during his Southern tour, and he ordered an animal     8     (make)in the likeness of his description and used in festivals from then on.

I love all about the lion dance. The other day, I saw a film about a left-behind teenager who insisted on pursuing his dreams despite difficulties and     9     (succeed)in lion dance. As Master Xu translates: “Heaven has made us talents; we’re not made     10     vain.”

8 . When he was fourteen, his ambition was to run a pub, just like his dad.     1     With a chain of restaurants, a number of popular television series and best-selling cookery books, Jamie Oliver is a well-known name in every UK household. I'm a huge “Jamie fan”. I admire his passion for improving the food we eat and helping people change their lives.

    2     He took fifteen unemployed young people, with no previous experience of cooking, and trained them to be top-class chefs (厨师) in his restaurant, also called Fifteen. I remember one trainee, Lloyd Hayes. He left school with no qualifications and started getting into crime.     3     I think it's this kind of success story that makes Jamie and his projects so special.

Another special project is Jamie's Ministry of Food which he started in 2008. There are two aims: firstly, to teach people how to cook healthy, affordable food instead of eating fast food; secondly, to set up the Pass It On scheme: encouraging each person to pass on a recipe they learned to four other people.     4     Thousands of people have changed their cooking habits as a result — and I'm one of them. I've decided I'm not going to eat fast food anymore.

It's not only adults, but children, too. Jamie's School Dinners, one of Jamie's best-known projects, tried to improve food in schools and encourage children to eat well. It was difficult to convince some of the children, but in the end, many schools improved their menus.     5    

So, what's Jamie going to do next? Well, whatever it is, one thing is for sure, I'm not going to miss it!

10 . Fast walkers may live longer than dawdlers (缓慢的人)— regardless of their weight, a new study suggests.

Researchers at Leicester University analyzed data on 474, 919 people with an average age of 52 in the UK Biobank between 2006 and 2016. They found women who walked briskly had a life expectancy of 86.7 to 87.8 years old, and men who kept up the pace had a life expectancy of 85.2 to 86.8. Slow walkers hadn’t much encouraging prospects (前景): women had a life expectancy of 72.4, and men of 64.8 years old, if they were more leisurely in their movements. According to the paper, published last week, that ratio held true even if the fast walkers were severely overweight. It does not necessarily mean fast walkers will live longer. Experts say it suggests walking speed could be a simple way for doctors to judge their patients’ general health alongside other tests.

It is hardly the first study holding up walking speed as a powerful evidence that appears to improve and determine our health.

In 2011, the Journal of the American Medical Association (JAMA) published a study by Stephanie Studenski, who found the same: walking speed was a reliable predictor of life expectancy.

In 2013, US researchers found walking pace was linked to lower heart disease risk and longer life expectancy. In 2018, a study from the University of Sydney found picking up your walking pace to even an “average speed” could cut your risk of premature death by a fifth.

And Tom Yates, the physical activity professor at Leicester who's behind the latest study, has been publishing findings on this connection for years.

In 2017, he analyzed the same UK Biobank data and found walking speed appeared to affect the risk of dying from heart disease — concluding that the slowest walkers were twice as likely to suffer a heart-related death compared to quick walkers.
