TIANJIN, Nov.23 (Xinhua)- Chinese scientists have signed a deal to establish a commercial animal cloning center in the northern port city of Tianjin, making the controversial science closer to mainstream acceptance.

The plant in the Tianjin Economic and Technological Development Area (TEDA), a government-sponsored business development park, will clone animals including sniffer and pet dogs, beef cattle and racehorses. Its main building is already under construction and due to be put to use in the near future, said a spokesman on Monday.

With an investment of 200 million yuan, the center will be jointly built by Sinica, Peking University’s Institute of Molecular Medicine, the Tianjin International Joint Academy of Biomedicine, and the Republic of Korea’s Sooam Biotech Research Foundation.

It will produce 100,000 cattle embryos a year initially, eventually increasing to 1 million, said Xu Xiaochun, board chairman of Boyalife Group, based in Wuxi. Chinese farmers are struggling to produce enough beef cattle to meet market demand, Xu said. The center, the largest ever worldwide, will also include a gene storage area and a museum, he added.

Scientists have cloned mice, cattle and other animals since the world’s first cloned sheep, Dolly, was born on July 5,1996 iii Britain. Since 2000, Chinese scientists have cloned sheep, cattle and pigs. China’s first commercial cloning company was established in September 2014 in Shandong with the birth of three pure-blooded Tibetan mastiff puppies.

Before this, cloning in China was limited to scientific research. More and more companies have shown interest in investing in the technology for commercial use, especially animal husbandry (飼養(yǎng)).

A. Artistic creation. B. Money making.

It was a cold March day in High Point,North Carolina.The girls on the Wesleyan Academy softball were waiting for their next turns at bat during practice,stamping their feet to say warm.Eighth-grader Taylor Bisbee shivered（發(fā)抖）a little as she watched her teammate Paris White play.The two didn’t know each other well—Taylor had just moved to town a month or so before.

Suddenly,Paris fell to the ground,“Paris’s eyes rolled back,”Taylor says.“She stated shaking.I knew it was an emergency.”

It certainly was,Paris had suffered a sudden heart failure.Without immediate medical care,Paris would die.At first,no one moved.The girls were in shock.Then the softball coach shouted out,“Does anyone know CPR?”

“I know I was really lucky,”Paris says now.“Most people don’t survive this.My team saved my life.”

Experts say Paris is right: For a sudden heart failure,the single best chance for survival is having someone nearby step in and do CPR quickly.

Today,Paris is back on the softball team.Taylor will apply to college soon.She wants to be a nurse.“I feel more confident in my actions now,”Taylor says.“I know I can act under pressure in a scary situation.”
