1 . 听下面一段较长对话，回答以下小题。

2 . Dance is one of the most wonderful forms of human communication. In many cultures, dance has both historic and cultural significance, which is communicated through learned gestures and expressions. Here are a bit more details about three of the world’s most beautiful dances.

Kathakali

Kathakali is a storytelling dance, during which performers use a variety of gestures, and eyes and facial expressions to communicate meanings. Costumes, hair styles, makeup and face paint, and jewelry also all hold specific meanings in the performance of Kathakali. There are nine facial expressions used to express emotions ranging from sadness and anger to curiosity. Through their expressions, it should be completely clear to the viewer what the performer is intending to convey.

Tango

The dance has its roots in an African slave dance called candombe, which is also a type of music. One key factor of a candombe performance is a partnered dance, which has over time developed into the modern tango. If you can keep your eyes on one part of the tango, just focus on the dancers’ legs and feet. The tango is typically performed low to the ground, with both performers’ steps often taking place at the same time. It’s complex and communicative.

Flamenco

One of the most interesting facts about the flamenco is that it began as a song. Over time, flamenco developed to include its now-famous passionate accompanying dance. One of the key factors of flamenco is palmas. It may look like simple, rhythmic clapping, but palmas are performed at different speeds,and strengths, and it is essential that the flamenco dancer understands how to make use of his or her hands as part of the performance.

3 . By day, Robert Titterton is a lawyer. In his spare  time though he goes on stage beside pianist Maria Raspopova — not as a musician but as her page turner. “I’m not a trained musician, but I’ve learnt to read music so I can help Maria in her performance.”

Mr Titterton is chairman of the Omega Ensemble but has been the group’s official page turner for the past four years. His job is to sit beside   the pianist and turn the pages of the score so the musician doesn’t have to break the flow of sound by doing it themselves. He said he became just as nervous as those playing instruments on stage.

“A lot of skills are needed for the job. You have to make sure you don’t turn two pages at once and make sure you find the repeats in the music   when you have to go back to the right spot.” Mr Titterton explained.

Being a page turner requires plenty of practice. Some pieces of music can go for 40 minutes and require up to 50 page turns, including back turns for repeat passages. Silent onstage communication is key, and each pianist has their own style of “nodding” to indicate a page turn which they need to practise with their page turner.

But like all performances, there are moments when things go wrong. “I was turning the page to get ready for the next page, but the draft wind from the turn caused the spare pages to fall off the stand,” Mr Titterton said, “Luckily I was able to catch them and put them back.”

Most page turners are piano students or up-and-coming concert pianists, although Ms Raspopova has once asked her husband to help her out on stage.

“My husband is the worst page turner,” she laughed. “He’s interested in the music, feeling every note, and I have to say: ‘Turn, turn!’ Robert is the best page turner I’ve had in my entire life.”

Why is Ms Raspopova’s husband “the worst page turner”?
