In India, a lot of elephants aren’t wild. Instead, they are domesticated (驯养的). They aren’t kept as pets,     1     as working animals. Every working elephant has its own keeper. An elephant and its keeper meet for the first time when they are both young.     2     (develop) a strong and lasting relationship, the elephant and its keeper grow up together. In fact,     3     (they) relationship continues for the rest of the elephant’s life — perhaps 40 years. Lots of elephants work in the forest,     4     (move) heavy trees after they are cut down. Some give rides to tourists, or carry people during     5     (celebrate) and festivals. Keepers try to take good care of their elephants, feeding them well and giving them     6     bath at the end of the working day.

Another animal     7     is treated in a special way in India is the cow. Cows are     8     (protect) animals, so they aren’t kept on farms or killed     9     food, although people do use their milk. So in India you can often see cows walking around in a town or city, and nobody tries to control them. If they sit down in the middle of the road, people     10     (usual) try to keep away from them. Do you think it’s interesting?

A new study found that    1    (own) a pet— particularly a dog—is good for the owner’s heart health.

The study looked at 1,768 people from Czech Republic and assessed (评估) them on seven kinds of health    2     (behave). Researchers then    3     (compare) the heart health scores of pet owners with those who didn’t own pets.

“In general, people       4     owned any pet were more likely to do more physical activities, better diet and blood sugar at an ideal (理想的) level,” researcher Andrea Maugeri said.“People who owned a dog can get the greatest     5     (beneficial) from having a pet.”

“Keeping a pet could be a    6     (hope) way of improving heart health,” Maugeri added, “because it would make you have a more    7     (physical) active lifestyle.”

In fact, the study is not the first to suggest that dogs can do good    8     our hearts. In 2013, the AHA said that dog owners have a    9     (low) risk of heart disease than people who don’t keep dogs because people with dogs    10     (be) more physically active.

For the sake of your fitness or slimness, besides dieting—cutting out junk food, you need to participate in sports as well, starting from some easier ones    1    more skillful and    2     (compete) ones, such as doing push-ups, jogging, track and field, soccer(playing the captain is even more interesting), skiing or even boxing and marathon as long as you have enough strength. You can also go to the gym for graceful gymnastics because working out makes you sweat. At the beginning you will find it hard, but before long you will make    3    .

Remember the 2018 Beijing Olympics, which    4    (host) in China as a huge success with numerous spectators? So many international athletes got    5    (involve) in various events,    6    the Chinese athletes did awesome jobs, with some masters    7    (create) legends and championships, winning medals and glory for our countries, and setting amazing examples. Even if they suffered    8     (injure)(sometimes their bones fell apart) and failures now and then, they persevered instead of losing heart or    9    (quit) with positive and strong determination, believing    10    they have stuck to with willpower will eventually make a difference, which does make sense.

Do you wish you could capture (捕捉) the     1    (excite) of a weekend beach trip? Would you like     2    (share) the view from your morning bike ride? If the answer is yes, consider     3    (buy) an action camera, whose functions will     4    (huge) improve your experience.

An action camera has a wide-angle lens     5     can record all the actions. You can put one on your bike's handle or just about anywhere. They are small and durable, so they can go wherever you go! Besides,     6     quality of the photos is more than acceptable, making     7     possible to appreciate them after the event.

There are lots of things to pay attention     8     when choosing an action camera. Above all look for one with high video quality and Wi-Fi connection. This will allow you to quickly view and edit videos on your smart phone. Other possible     9    (character) include time-lapse and slow-motion video modes. You can use these to speed up or slow down time in your videos!

Whichever model you choose, you     10    (enjoy) sharing impressive videos of your adventures. An action camera is also of great use for activities with friends and families.

The Terracotta Army is a collection of 8, 099 life-size terracotta statues of warriors (勇士) and horses     1     (discover) by accident in 1974 at Xian, in China. The terracotta army was guarding the tomb of the First Emperor of China, Qin Shi Huang     2     lived over 2200 years ago. Its construction began in 246 B. C. and     3     is believed to have taken 700,000 workers 36 years to finish. Since then discoveries     4     (continue) to be made at the site and the remains of nearly 8000 terracotta statues have been recovered.

Of the three pits, Pit 1 is the largest and the     7     (impress) , with over 6,000 terracotta statues in total and fewer than 2,000 on regular display.

The terracotta warriors are unique. Not only are they life-size and individually modelled in clay, but the detail of the statues is     8     (surprise) . Each statue is different in facial features and expressions, clothing, hairstyle and also body position. There has been worldwide fascination in the discovery of the Terracotta Army and it is now regarded     9     the 8th Wonder of the Ancient World. The Terracotta Army is not only China’s great historical attraction,     10     it is one of the most significant archeological (考古的) finds in the world and one of the greatest discoveries of the 20th century.

Jack and his partner Mark Victor Hansen once pitched (推销) the original Chicken Soup for the Soul to many different publishers. But    5    (sad), none of these publishers were interested    6     it, and they said no one wanted to read 100 inspirational stories. However, they were determined to get the book    7    （publish). Finally, their book was picked up by a publisher.

So far, the Chicken Soup for the Soul series    8    (have) more than 500 million copies in print in over 40 languages. If they had given up, these inspirational stories certainly would not have been read across    9     world and they wouldn’t have been such a great    10    (achieve).
