The homeless dog, known as Xiao Sa, has been following a team of cyclists for 24 days along 1,833 kilometers of highway from Kangding, Sichuan province, to Lhasa in Tibet.

Nobody knows where the white dog came from or how long she has been straying on highway G318. Netizens call her the "dog with determination" and the micro blog "Go Go Xiao Sa" recording her life has attracted more than 37,000 followers in two weeks.

A picture of Xiao Sa in the arms of a young man in front of the Potala Palace on Thursday night drew more than 4,000 comments congratulating the small dog and expressing dreams of going to Lhasa.

The young man in the picture is Zhang Heng, 22, a student in Wuhan, Hubei province. As his graduation trip, he decided to face the challenge of riding to Lhasa alone. On the way he met a lonely dog. "She was lying, tired, on the street around Yajiang, Sichuan province," he said. "So we fed her, and then she followed our team.”

"We felt she might want to come along with us, so we decided to bring her along to the end." A week later, Zhang and his buddies opened a micro blog account for her. "We thought the dog was encouraging us, and wanted others to know its story," he said. They created the name Xiao Sa by combining xiao meaning "little" with the last syllable of Lhasa.

During their journey, Xiao Sa, Zhang and his team covered more than 1,700 kilometers and climbed 10 mountains higher than 4,000 meters. Xiao Sa just ran up the mountains or along dirt roads.

"Many people stopped cycling in some sections, then took the bus, but the dog made it," he said. Zhang put the dog on the back of the bike when the team was riding downhill. "The speed can reach 70 kilometers per hour, impossible for the dog to catch us."

Zhang Heng, who accompanied Xiao Sa for 20 days, called her "a buddy and a friend". "I would like to take the dog home and take care of her. She has been a stray on the road for a long time. She needs a home."

归纳法是高中化学学习常用的方法之一，某化学研究性学习小组在学习了《化学反应原理》后作出了如下的归纳总结：（均在常温下）

①pH＝1的强酸溶液，加水稀释后，溶液中所有离子的浓度均降低。

②pH＝2的盐酸和pH＝1的醋酸，c（H^＋）之比为2∶1。

③在Na₂CO₃和NaHCO₃溶液中均存在下列关系c(Na⁺)+c(H⁺)=c(OH^-)+c(HCO₃^‑)+2c(CO₃^2-)

④反应2A (s) + B (g)＝2C (g) + D (g) 不能自发进行，则该反应△H一定大于0

⑤已知醋酸电离平衡常数为K_a；醋酸根水解常数为K_h；水的离子积为K_w；

则三者关系为：K_a·K_h＝K_w

⑥反应A（g）2B（g）；△H，若正反应的活化能为E_akJ·mol^-1，逆反应的活化能为E_bkJ·mol^-1，则△H =（E_a－E_b）kJ·mol^-1。其归纳正确的是

A．①②③⑥

B．③④⑤⑥

C．②④⑤⑥

D．①③④⑤

“传统是一种巨大的阻力，是历史的惰性力，但由于它只是消极的，所以一定要被摧毁。”种观点是( )。
