1 . 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.

5 . How to fight your bad breath

More than 80 million people suffer from bad breath, according to the Academy of General Dentistry, a professional association of dentists from Canada and the United States.     1    , the most common reason is poor oral hygiene (卫生). Here are some ways to fight bad breath and bring others talking to you a more pleasant experience.

    2    .

Onions and garlic add flavor to many foods, but they also add odors (臭味) not easily brushed away. The substances that cause their bad smells make their way into your bloodstream and travel to your lungs, where you breathe them out. The best way to avoid the problem is to avoid such foods.

Avoid dry mouth.

Saliva (唾液) is the key thing in your mouth that helps keep the odor under control because it helps wash away bacteria.     3    , try drinking water or chewing sugarless gum.

Brush and floss (用牙线清洁).

Oral hygiene experts recommend you brush your teeth at least twice a day and floss at least once to reduce plaque (牙斑). The sticky buildup on your teeth collects bacteria that cause bad breath, and trapped food adds to the problem.     4    , the experts warn. If you brush too hard you can wear down your teeth.

Brush your tongue.

    5    . To rid your tongue of odor-causing bacteria, remember to brush it when you clean your teeth. If your toothbrush is too big to reach the back of your tongue, buy a scraper, which is designed specifically to apply even pressure across the surface of the tongue area. This removes bacteria and dead cells that brushing alone can’t take care of.

A．Avoid certain foods

B．Don’t overdo things, though

C．If you aren’t producing much saliva

D．Bacteria don’t just live on your teeth

E．Brush your teeth after you eat these foods

F．Although bad breath can happen because of medical reasons

G．If your bad breath is thought to be caused by a potential health condition

6 . 阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

“No 7, Jobie Nymble, takes the lead,” cried the announcer. “Just one more hurdle (跨栏) and ...” Cheers broke out. “Jobie Nymble from Riverside Middle School takes first place in the girls’ 100-meter hurdles!” The crowd went wild.

“County championships (锦标赛), here we come,” screamed Jobie, patting her green track spikes (钉鞋). They were her lucky shoes and she loved them. “Next Saturday, we’re taking home the gold,” Jobie whispered to her spikes, excitedly retying them.

“Don’t forget, guys,” said Marisol, one of her teammates. “My birthday party is next Friday at Hidden Park.”

Next weekend couldn’t come soon enough. Jobie smiled with excitement all week long. At track practice, she leaped over those hurdles faster than she’d ever leaped before. And it wasn’t long before everything in her path was a hurdle: flowerpots in her front yard, sidewalk cracks on the way to the bus stop and even her little sister, Teka!

The day of Marisol’s party, Jobie put on her favorite outfit: her blue shorts, an old track T-shirt from her dad, and her lucky spikes. “Perfect.” She smiled at herself in the mirror.

The party was under way when Jobie arrived at Hidden Park. She stopped by the track first, planning to do some practice.

“Jobie!” Two of Jobie’s teammates rushed toward her, breathless and barefoot. “Come on,” they yelled. “You have to try the slide.”

Jobie looked toward the party area. Suddenly, she saw it. The biggest slide she had ever seen was on the far side of the park. Smiling kids zoomed down the slide at unspeakable speeds. Without thinking twice, Jobie took off her spikes and dashed (猛冲) toward the slide. Its ladder stretched to the sky, but she reached the top in no time, closed her eyes and let go.

Jobie couldn’t get enough. She tried again and again. When it was finally time to go home, she unwillingly made her way back to the track where she’d left her shoes.

9 . On a bright morning on the warm sands of Hawaii, US, I made what could possibly be one of the unwisest choices of my life. I decided to follow in the footsteps of my friends... who were jumping off of a cliff (悬崖) – into water, of course.

It was over 30 feet (9 meters) high, extremely rocky and completely terrifying. There were only two ways to get up the cliff: either swim out in the ocean to an area where you could scale (攀登) a slippery sea wall that had crevices (裂缝) to grasp, or traverse (穿过) across sharp rocks to reach the point on the cliff where it was safe to take the leap of faith into the water. Both routes had their risks yet were also safe enough to use, so eventually, I chose the latter.

It was probably wiser to swim out to sea and climb up the wall, which, sadly, I learned too late. To my disappointment, crossing the rocks was much more difficult than I had originally thought. It took me a while to walk across the first stretch of rocks near the water, mostly because the rocks were damp due to waves crashing against them, and because there were huge insects that were crawling (爬行) across them. The rest of the time I was just focused on making sure I kept my footing. So far, no one had been injured by climbing or jumping off the rocks, so I was determined to get up there safely as well. Surprisingly, I did.

From afar, the spot that people were jumping off from looked like no big deal. It didn’t appear to be too high or too scary to leap from, but I was very wrong about that. It was surreal (离奇的) standing on top of the cliff and looking out at the ocean that lapped at the rocks below me. However, I wasn’t in the mood to stay standing at the edge of a cliff and thinking about my very poor life choices, so I decided to complete the inevitable (不可避免的) task as soon as I could. Without a second thought, I jumped off the cliff.

Time seemed to slow as I plummeted (骤降) down towards the sparkling blue sea. It was more terrifying than any roller coaster (过山车) I had ridden before, but also more fun. I hit the water with a painful “smack!” because I had landed wrong, but I loved it! I ended up deciding to give it another go.

10 . Known as “ships of the desert”, camels have long been used for transport across the sands. However, for people in the United Arab Emirates (阿拉伯联合酋长国), camels are also beauty pageant contestants (选美比赛选手).

They have strict criteria (标准) to judge a camel’s beauty, including the size of its head, the length of its neck and whether its mouth can cover its teeth. Not every camel is blessed with (赐予) pretty lips or a long neck, so locals have turned to cloning.

Reproductive Biotechnology Center in Dubai, UAE, is the only clone facility in the Gulf, according to CCTV. “We have so much demand for cloning camels that we are not able to keep up,” the center’s scientific director, Nisar Wani, told AFP.

“We are now producing plenty, maybe more than 10 to 20 babies every year. This year we had 28 pregnancies (怀孕) so far; last year, we had 20,” Wani said.

“Beauty queens” are the most popular order. Clients will pay between $54,500 to $109,000 (about 350,533 to 701,066 yuan) to duplicate (复制) a camel. “The price of the camel is determined according to its beauty, health and how well-known the breed (品种) is,” Saud al-Otaibi, who runs a camel auction (拍卖) in Kuwait, told AFP.

Beauty pageants are not the only driver of the camel cloning industry. Many customers want to reproduce camels that produce large amounts of milk. “We have cloned some camels that produce more than 35 liters of milk a day,” Wani told AFP. “Normal camels produce an average of 5 liters a day.”

On April 8, 2009, Dubai claimed the world’s first cloned camel, Injaz. From the minute Injaz was born, there was no going back.

The center is producing “racing champions, high milk-producing animals ... and winners of beauty contests”, added Wani.

Cloning animals comes with concerns. Some scientists worry that continued use of this technology could lead species to extinction via “genetic bottleneck (种群遗传瓶颈效应)”, which happens when species lack genetic diversity .Cloning is also costly and incredibly hard to get right–up to 90 percent of attempts to clone animals end in failure, according to Wired, a US magazine.

1. What can we learn about camels in the UAE?

A．A beauty contest for camels is held annually.

B．They are no longer used for transport in desert.

C．Only those that meet the beauty criteria will be raised.

D．Cloned camels are in great demand.

2. How many cloned camels has the Reproductive Biotechnology Center planned to produce this year?

A．10	B．20
C．28	D．32

3. Why have the locals turned to cloning camels?

A．To save camels from extinction.

B．To get healthier breeds of camels.

C．To get camels that are more beautiful and more productive.

D．To overcome the genetic bottleneck of camels.

4. What are scientists most concerned about when it comes to cloning animals?

A．It could lead to extinction of the species.

B．Not many people could afford the high cost.

C．It could take scientists many attempts to succeed.

D．It could cause some genetic diseases.
