英国新闻听力 克隆羊多利姐妹健康 哈利波特舞台剧上映

Researchers in the British city of Nottingham say the cloned siblings¹ of Dolly the sheep are in good health raising hopes that the process doesn't effect physical wellbeing. The four cloned sisters have just passed their ninth birthdays. Dolly who had to be put down in 2003 had aged² prematurely³ because she developed osteoarthritis at a relatively⁴ young age. Here is our science correspondent Jonathan Amos.

Dolly's birth was a sensation, the first genetic⁵ copy of a mammal made from a cell taken from an adult sheep. It was how it is a way of developing new medical therapies or to save endangered species. But cloning is very inefficient⁶. Most attempts fail and even in Dolly's case, she had a lung disease and painful joints⁷. Scientists wondered if that was because her genetic clock had not been reset⁸ properly. That possibility has now been tested in four sheep cloned from the same cells as Dolly. They are her genetic sisters called Debby, Denis, Dianna and Daisy. They are now nine, older than she was but don't show the same degenerative issues. Claire from Nottingham University says this finding renews hope in the promise of cloning but concedes the process is still too inefficient.

And so there still remains⁹ an ethical¹⁰ and welfare concern with cloning. And what we have to do is to reduce the incidents of theses losses and the severity of these losses before I think the technique will be widely accepted by the general public.

The scientists who report their studies in the journey Nature Communications say it's been fascinating to work with animal copies. Some do develop quite different personalities¹¹. But they are virtually impossible to tell apart.

That report from Jonathan Amos.

It seems to have been around for quite a while that this weekend after two months of previews, we will see the gala opening in London of Harry¹² Potter and the Cursed Child. It's described as the eighth Potter story. But the critics have been allowed in ahead of the official opening and the reviews are now in the newspapers. So what's it about? A question for our arts correspondent Vincent Dowd.

It's a five-hour epic¹³ in two parts so I can't say much about it. And of course I'm not really supposed to say that much about it anyway. There is a lot in it basically set 19 years after the end of the novels or the films. Harry played now by Jamie Parker is 37.

What have the critics made of it all so far?

They have loved it. I think without exception. I'm not sure I can remember reviews like this since the producers are in New York. Just one or two quotes, The Times, "It's the real deal live in front of you, so much better than any film could be".

英国城市诺丁汉的研究人员称，多利的克隆姐妹健康状况良好，让人开始相信这个过程不会影响身体健康。这四个克隆姐妹刚刚过完她们的9岁生日。多利在相对年轻的岁数患上骨关节炎，因此未老先衰，2003年不得不被实施安乐死。本台科学记者乔纳森·亚摩斯报道。

多利的出生曾轰动一时，她是从成年羊的细胞制造出来的第一个哺乳动物副本。当时这是开发新药物疗法或拯救濒危物种的一种方式，但克隆非常低效。大多数尝试都失败了，即便在多利的案例中，也有肺部疾病和关节疼痛。科学家怀疑这是不是因为没有恰当重置她的基因钟。这个可能性在四只和多利来自同一细胞的克隆羊身上得到了试验。她们是多利的亲姐妹，分别叫黛比、丹尼斯、戴安娜和黛西，现在9岁了，比多利当时的年龄要大，但她们并没有退化的问题。诺丁汉大学克莱尔称，此发现重新燃起了人们对克隆的希望，但他承认这个过程还是太低效。

人们对克隆技术还是存在伦理和健康方面的担忧，我们要做的是减少这些损失的数量和严重程度，然后我认为这项技术才会为公众广泛接受。

科学家们在《自然通讯》杂志上报道了研究成果，他们说和克隆动物相处非常有趣。有些克隆动物性格迥异，但长相真是无法区分。

下面这则新闻似乎宣传很长时间了，经过两个月的试映后，本周末我们将在伦敦见证《哈利·波特与被诅咒的孩子》的欢乐开幕。它被描述为《哈利·波特》第八部，但在正式开幕前，评论家得以先睹为快，他们的评论已见报端。那具体情况究竟是怎样的呢？我们把问题交给本台记者文森特·多德。

它是时长5个小时的具有史诗性质的舞台剧，所以我也评论不了那么多。当然，我也实在不用说那么多。大部分剧情设置在这本小说或电影完结后19年。哈利·波特现在的扮演者杰米·帕克37岁。评论家目前都怎么看？

他们大爱这部作品，我觉得无一例外。因为制作人在纽约，所以我记不太清评论怎么说了。这儿有一两句话，来自《泰晤士报》，"它是展现在我们面前的实况直播，比电影好看多了"。
