If you are like most young people, you’ll have been online     1     used a phone at some point today. A bit of screen time is fine – especially if you are studying, socializing or simply relaxing. Yet too much screen time can be bad for your brain.

A recent study of more than 4,000 children found that those who     2     ( play) on a screen anywhere did not do     3     (well) in thinking tests than those who seldom used mobile phones.     4     (stare)(盯着) at things online can also mean that you are missing out on the real world. Every hour looking at a screen     5     (be) an hour you can spend being with your friends or learning a new exciting hobby.

If you are worried that you are spending too many hours scrolling (滚动) through social media feed, glued to the television or     6     (addict) to games, you might want to think about cutting down a bit, or even going cold turkey,     7     means giving up completely, instead of     8     (cut) back.

See if you can go     9     (total) screen-free for a week, a month or whatever you feel you can manage. If that’s too hard, just cut out one thing, such as games. You might even feel differently about your favorite gadgets (小装置) when     10     challenge is over.

Ocean Park Hong Kong is one of Hong Kong’s greatest tourist     1     (attract). Because the park isn’t run for profit, it is much more suitable for education and wildlife conservation research. And     2     (compare) with other theme parks, it takes better care of the animals. In addition, you will find prices there fairly reasonable considering the size and the quality. Therefore, since its opening, the park     3     (draw) a large number of visitors.

    4     (cover) about a square kilometer on the southern side of Hong Kong Island, the theme park is conveniently close to downtown. As the park attracts large crowds every day, try to be there     5     the park opens at 10 in the morning and avoid the busy holidays and weekends. It is also recommended that tickets     6     (buy) online in advance.

Hong Kong is a unique city in the world     7     you can buy one card to pay for public transport and all your purchases.     8     card is available at the ticket windows of any subway station in Hong Kong, with which then you can pay for things in the park. And you can add money as you wish and have     9     returned to a station window for the remaining money back.

Wish you an     10     (enjoy) day in Hong Kong’s most popular theme park.

8 . Hurricanes could be lasting longer after they make landfall, and spreading their damage farther inland, a new study suggests, which is a previously undescribed effect of climate change.

The study, published in the journal Nature, analyzed hurricanes that have struck North America from 1967 to 2018. It found that hurricanes making landfall in the 1960s lost 75 percent of their power in the first day after coming ashore, while today a hurricane that strikes land typically decays by about 50 percent in the first day.

The study’s authors claimed rising ocean temperature is the driving force behind the formation of longer-lived hurricanes. They ran four models that simulate (模拟) a hurricane moving over land. In each, they adjusted the temperature of the ocean water underneath the storm. The higher the sea surface temperature was, the researchers found, the more moisture (水汽) a storm carried over land and the longer it lasted. They said if a hurricane is like an engine, the warm ocean water beneath it is like fuel. When ocean water is particularly warm, as it is in the Caribbean and Gulf of Mexico, it can increase pressure on hurricanes. If human-caused climate warming continues, they added, the destructive power of hurricanes—some with 100-plus-mile-per-hour winds and heavy rainfall—could extend farther inland and especially affect ill-equipped communities.

James Kossin, a climate scientist at the National Oceanic and Atmospheric Administration (NOAA), said, “They make a convincing case that the long-lasting hurricane is related to higher ocean temperature, and this can in turn be linked to climate change.”

“I would probably support the opinion that this phenomenon (现象) is possibly happening,” said Dan Chavas, an atmospheric scientist at Purdue University and one of the study’s reviewers. “I think the effect is very real, but the question is how strong the effect is. We still have a long way to go.”

9 . You probably know Machu Picchu and the Taj Mahal as famous UNESCO World Heritage sites—structures and monuments of great cultural value. But what about Beijing opera? Or the art of pizza-making in Naples? What do these have in common?

Traditions like these are known as “intangible cultural heritage”. In comparison with UNESCO World Heritage sites, intangible heritage does not include buildings like palaces and temples. Instead, it includes traditional art forms, such as music, dance, and craft-making—living traditions that are an important part of a place’s culture.

UNESCO began to identify cultural traditions in 2008. By 2017, UNESCO had approved (批准) more than 300 diverse practices. These include cultural events like the Chinese Dragon Boat Festival, performing arts like Spanish flamenco, and handicrafts like Japanese washi paper-making. In 2010, UNESCO also began to include important regional cuisines, starting with French and Mexican food.

Cultural rituals (仪式) are an important part of the UNESCO list. An example is the Tlemcen wedding ceremony in Algeria. The ceremony begins in the bride’s parents’ home, where friends and female relatives help the bride prepare for the ceremony. The bride is first dressed in a golden silk dress. Before leaving the house for the ceremony, her face is wrapped in a golden silk veil (面纱). Later, during the wedding feast, the bride removes her veil, ready to be married. The tradition has passed from one generation to the next, and marks the community’s cultural identity.

Some of the cultural items on the list are dying out and in need of protection. An example is Al Sadu—a traditional form of weaving in the United Arab Emirates. The tradition was once widely practiced by communities of desert Bedouin women. However, as many Bedouins have now moved to cities, Al Sadu is mostly practiced by older women whose number is decreasing.

UNESCO hopes that by bringing attention to cultural traditions such as Al Sadu, they will be more likely to survive. “Cultural traditions are important to fight for.” says Cecile Duvelle of UNESCO. “The more globalized the world becomes,” she adds, “the more important it is not to lose these traditional roots.”

10 . A farmer had some puppies to sell. He was putting up a _________ advertising the dogs in his yard when he felt a tug (拉扯) on his trousers. He _________ and saw a little boy.

“Mister,” he said, “I want to buy one of your puppies.” “Well, they come from _________ parents and cost lots of money,” answered the farmer. Then the boy reached into his pocket and pulled out a handful of _________. “I’ve got 89 cents. Is that enough _________ to take a look?”

“Sure,” said the farmer. And he _________, “Here, Dolly!”

Out from the doghouse ran Dolly _________ by four little balls of fur. The boy pressed his face _________ the fence, watching in _________

As the dogs made their way to the farmer, he noticed __________ inside the doghouse. It was another little fur ball, noticeably smaller. It __________ walked out toward the others, doing its best to __________. “I want that one,” the boy cried out.

The farmer __________ at his side, “Son, you don’t want that puppy. He'll never be able to __________ with you like these others.”

With that, the boy stepped back, bent down, and __________ one leg of his trousers. There was a __________ made shoe with a steel brace (支架) supporting the leg. “Sir, my leg fails me too, and he’ll need someone who __________,” he said.

With tears in eyes, the farmer __________ picked up the little puppy and __________ it to the little boy.

“How much?” asked the boy.
