2 . Against all our wishes, advertising works, which is why, even in hard economic times, Madison Avenue is a $34-billion-a-year business. And if Martin Lindstrom, a marketing consultant is correct, trying to _______ the advertisement is about to get especially hard.

83% of all forms of advertising principally _______ only one of our senses: sight. Hearing, however, can be just as powerful, though advertisers have taken only limited advantage of it. Historically, ads have relied on slogans (广告语) to catch our ear, _______ everyday sounds — a steak sizzling (发嘶嘶声), a baby laughing and other sounds we can't help paying attention to. Weave these everyday sounds into an ad campaign and we customers may be _______ to resist them.

According to Lindstrom, the everyday sound that is most impressive, both in terms of interest and _______ feelings, is a baby laughing. The other high-ranking sounds are also powerful — the sound of a car engine or a soda being poured.

In all of these cases, it doesn’t need an experienced advertisement designer to invent the sounds, associate them with meanings and then play them over and over until the subjects _______ them. Rather, the everyday sounds already have meanings and thus can cause a kind of _______: hunger, thirst or happy expectation.

Some TV ads have already given viewers close-up shots of meat with sizzling sounds. And retailers are _______. Lindstrom is now consulting with clients, intending to pipe the sound of filtering coffee or fizzing soda into the drink department or that of a baby laughing sound into the baby-food section.

Of course, this doesn’t mean that advertisers can just press the audio button _______ and consumers will come eagerly. Indeed, sometimes customers flee. In the early years of cell-phone use, the ringtone (铃音) of a famous cell phone brand was recognized by many people in the U.K., but soon it became widely ________. That, Lindstrom says, was partly because so few users observed cell-phone manners and ________ accidents kept happening in places like movie theaters. The computer start-up sound has taken on the similarly negative ________, because people so often hear it when they’re restarting the computer after it ________. In these cases, manufacturers themselves may as well revise the bothersome sound or ________ it entirely.

Lindstrom’s experiment also shows that people respond to a sound better when it’s ________. If nothing else, smart marketers may at least keep the volume low.

3 . A depressed grandmother in Durham, England, has been surprised since receiving a mysterious greeting card.

______ suffering from dementia (痴呆) and depression, she is also ______, according to her granddaughter Melly. Every day without ______, the grandmother sits by the window at her home so she can ______ at passers-by.

Not much has ever come from the elderly woman’s daily life, ______ she received an unexpected holiday card in her ______. “To the lady who waves and smiles, with Christmas wishes,” ______ the card. “It’s nice to see you ______ and wave when I walk past your house. Please accept my small gift to give you another ______ to smile.”

Melly later published the ______ story on Twitter so she could wish the ______ woman a Merry Christmas and thank her for the note. “My grandmother is disabled and has dementia,” explained Melly in a tweet. “She ______ in her chair by the window all day, every day — just looking outside and normally feeling ______ as we all work during the day. When we went to see her today, someone had ______ this through the letter box.”

Since the story was posted on the Internet, it has been ______ thousands of times. Not only that, but Twitter users filled Melly’s mailbox with pictures of their ______ since she also mentioned ______ her grandmother loves animals.

“She’s been so ______ recently, feeling unhappy. I can’t put into words how much this has ______ her!” Melly wrote in several follow-up posts. “She’s ______ eaten for weeks because she’s been so down and I’ve just made her a sandwich and she’s happily enjoying it. I can’t wait to tell my grandmother how many people have wished her well.”

4 . In July, a two-minute-long video began spreading on the Internet. The video featured a _________ ballet student dancing in the rain. As the rain falls, forming small _________ between the unsmooth ground on which he dances, Anthony, 11, _________ round and round.

The _________ has been seen more than 20 million times on social media platforms, which has turned a _________ on the unlikely story of a ballet school in a poor suburb of Lagos, Nigeria: The Leap of Dance Academy. Founded by Daniel in 2017, the academy has _________ the lives of its students, affording them a place to _________ and to dream.

For now, the Leap of Dance Academy is housed at the home of its _________, Daniel. Every day after school, 12 local students make their way to his apartment. He _________ his furniture for more space and __________ a thin sheet over the cement (水泥) floor for class. What is the most __________ is that the mirror was glued by dozens of broken mirrors.

“We have __________ from so many people. We appreciate their letters, in which they say they are __________ by the students and by dance,” Daniel said. “They felt our __________ and came alive. They __________ us that art is here to stay.”

Some netizens remarked: “This is a realistic portrayal from a poor boy to ballet prince. Anyone with a dream is great.”
