任务型阅读(共10小题;每小题1分,满分10分) On the morning of Apr. 20, different from any other Saturdays, a powerful earthquake which measured 7.0 magnitude occurred in Ya’an, Sichuan Province. The quake happened close to the area where 70,000 died when another powerful hit took place in 2008. The 4.20 earthquake shook Sichuan with 208 people missing or dead. Nearly 14, 000 are reported to have been injured. Thousands of buildings collapsed, leaving victims homeless. Water and electricity supplies were cut off, which left concerns about the welfare of the survivors. In Lushan, where the most of the damage was concentrated, facilities of communication broke down. Victims lost contact with the outside world. All the country have been shocked at the tragic news. Numerous relief is pouring in from all over China to the victims of the Lushan earthquake. Governments of all levels have taken some efficient measures to relieve the impact of earthquake. On Sunday, Chinese Premier Li Keqiang made it to the worst-stricken Lushan, issuing several statements to ensure rescuing the buried and other injured people. Meanwhile, he visited some of those being treated for their injuries in the temporary hospitals set up with an open-air emergency facility. Rows of Red Cross tents are now home to some of the thousands left homeless by this deadly earthquake. State media says thousands of troops along with volunteers help with the rescue operation and to hand out supplies. People from across the country are called on to donate to relieve and help rebuild the earthquake-hit area. Lots of students ranging from university students to kindergarten kids have given away their pocket money just to do their own bit in this relief campaign. Hong Kong special government at first proposed to donate 100 million HONG Kong dollars, which was rejected by some of members of government’s parliament(议员), who questioned whether China’s Red Cross could put every cent into practical use honestly, for in 2008 Wenchuan earthquake China’s Red Cross failed to make it clear how they spent the charity money. Anyway the proposal was at last passed on May 3. At the same time, China’s Red Cross, determined to make a bit change, promised to give a detailed account of where every cent would go.
