英国新闻听力 奥巴马努力为伊朗核协议做辩护（在线收听）

Within the last few minutes, Greek MPs have approved a tough set of bailout conditions imposed by the European Union. Brussels has said that the Parliament must accept its demands before talks on a new rescue package for the Greek economy could begin. In the final appeal for a YES vote, the Prime Minister Alexis Tsipras repeated that he did not believe the measures, but that there were no alternatives to acceptance. He was given a standing ovation by supporters, but many other MPs spoke out angrily against the EU package.

The US President Barack Obama has stressed that the deal reached on Tuesday over Iran’s nuclear program presents an once-in-a-lifetime chance for a safer world. Under the agreement, strict limits will be imposed on Iran’s nuclear activities in return for the lifting of crippling economic sanctions. Jon Sopel reports from Washington.

"Almost more striking than what President Obama said at his news conference about the Iran deal was the tune in which he said it. He came out swinging, confident in his argument, all the fact seemingly at his fingertips, came to make the case that on the central goal of stopping Iran obtaining a nuclear weapon, this agreement had to be supported. The president has said there’ll be a robust debate with the Congress. It looks like one he’s going to relish.”

Militia fighters in Yemen backed by Saudi-led airstrikes have driven Houthi rebels out of much of the southern city of Adem. The new offensive in support of the exiled president Abdu Rabbu Mansour Haddi was launched on Tuesday. Sebastian Asher reports.

"This has clearly been the biggest setback the Houthis have suffered since the Saudis began an air campaign against them in support of president Haddi in March. The success of the local militias in the new offensive may be due to the fact that they’ve received better arms recently from the Gulf supporters and being boosted by Saudi trained fighters. The Saudi-led coalition has also coordinated closely with them in its airstrikes. The Houthis have lost the airport, much of the port and other key districts. But there are many other battle grounds in Yemen. Adem was always a very long way from a Houthi's heartland in the north."

There, it was announced he was replacing the region’s governor, interior ministry chief and security head. It’s still unclear what sparked the shootout.

Right Sector members reportedly used automatic rifles, grenade launchers, and a hand-fed machine gun."

An attempt by Mexico to open up its oil industry to foreign investors for the first time in 80 years has fallen short to the government’s expectations that only two of 14 exploration blocks in the Gulf of Mexico were rewarded at an auction broadcast live on television.

High-definition images of the dwarf planet Pluto revealed that it has huge ice mountains and canyons as big as anything on earth. The images captured by the US space agency NASA’s New Horizon’s probe on Tuesday are the most detailed evertaken of Pluto. Our science correspondent Jonathan E was at mission control in L, Maryland to see the pictures coming.

"After yesterday’s dramatic flyby, there was high anticipation for this presentation. The first pin sharp view of the enigmatic little planet at the edge of our solar system. The invited university audience was an informed one. But even they were drawn to a gasp and clapped at every new image. The big surprise is how few the craters are seen, something you would expected in old surfaces. This means this world may still be active, reshaping themselves through some process that is yet to be explained."

在沙特空袭支持下的也门民兵武装将胡塞叛军从南部城市亚丁市大部分区域驱赶走，这次为了支持流亡总统哈迪的新进攻是周二开始的。塞巴斯蒂安·亚瑟报道。

“这显然是自三月份沙特为支持总统哈迪进行空袭以来胡塞叛军遭遇的最大措施，当地民兵之所以能在这次进攻中取得胜利，可能是因为他们从海湾支持者那里得到更好的武器，还得到沙特培训的武装分子的支持。以沙特为首的联盟还在空袭中与他们紧密配合，胡塞叛军已经失去了机场，港口的大部分，以及其他关键地区。但也门还有其他许多战场，亚丁距离北部胡塞叛军的腹地很远。”

有关矮行星冥王星的高清图像显示该行星上有像地球上那么大的巨大雪山和峡谷，这些图像是美国航天局的“新视野号”探测器捕捉的，是为目前为止有关冥王星的最详细图像。BBC科学记者乔纳森在马里兰州太空航行地面指挥中心观看图片发回。

“经过昨天的戏剧性飞掠，人们对这些图片的呈现抱有很高的期待。这是我们太阳系边缘上这颗神秘星球的首批清晰图片，被邀请来的大学观众们知识渊博，但即使是他们也急于抢着看每张新图片，最令人吃惊的是上面的陨石坑很少，与过去看的星球表面不同，这意味着这个世界仍很活跃，通过尚无法解释的过程继续塑造自身。”
