 In 2015, on a TV show I Am a Singer 3, Li Jian became the most popular one, because he has great singing ability and sense of humor. Li has a smooth voice. His songs can really touch the listeners. People even give him the nickname "Poetic Musician" because of his poetic lyrics.

 Li was born in Harbin in 1974. He showed great talent for music from an early age. He learned to play the guitar by himself. Later, he became a good guitarist and won the first prize in a national competition. “In my younger days, guitar was like my best friend." Li said.

 Though he studied electronic engineering in Qinghua University, he never gave up music. Then in March 2001, Li formed a group called Shuimu Nianhua with his friend. Later, Li didn't agree to change their musical style. So the pair went their separate（分离）ways next year.

 Unlike some other musicians, Li does very few interviews or concerts. He spends more time writing songs. "Writing songs is like collecting water in a cup. When the cup is full, the water will come out naturally." he said.

妈妈买了一束花放在盛有自来水的花瓶中，但一般几天后花就会枯萎。小佳认为如果花瓶中加入的是矿泉水，花会保存更长时间。请完善她的实验方案，并预测可能的结果：
实验目的：探究自来水和矿泉水对插花保存时间的影响。
实验步骤：
①在花店中购买开花状况基本相同的花20枝；
②取大小相同的花瓶10个，分为A、B两组，每组5个；
③向A组每个花瓶加入500ml自来水，向B组每个花瓶加入____  ml矿泉水；
④在每个花瓶中插放2枝花，并将花瓶放在家里____ （填“相同”或“不同”）的位置；
⑤每天观察花的枯萎情况并做记录，最后计算出A、B两组的花开始枯萎时的平均天数．
实验结果及结论：
Ⅰ：若花开始枯萎时的天数是A组____ （填“多于”、“少于”或“等于”）B组，则矿泉水更利于用来插花；
Ⅱ：若花开始枯萎时的天数是A组____ （填“多于”、“少于”或“等于”）B组，则自来水更利于用来插花；
Ⅲ：若花开始枯萎时的天数是A组与B组相同，则矿泉水和自来水对插花保存时间影响差不多。
