Australia

Goodbye to the bears

Koalas, a symbol of Australia, may die out within 15 years as the growth of towns along the east coast destroys their fragile (易毁坏的) habitats.

A survey of the koala habitats found that about 30 percent were no longer home, while 60 percent had suffered much destruction. The Australian Koala Foundation has written to the government urging it to declare the koala an endangered species. At present, there are about 100,000 koalas in Australia.

Iraq

Rebel attacks worsen

More than 100 people, including three US soldiers, were killed in bloody attacks in five Iraqi cities last Thursday. At least 300 people were wounded.

The violence was part of efforts made by Iraqi rebels (反抗者) and foreign militants to ruin the formal handover to Iraqi rule in six days’ time. A group headed by al-Qaida-linked (和基地组织有联系的) terrorist Abu Musab al-Zarqawi said they were responsible for the attacks.

Shenzhen’s salaries are the best

A survey showed average annual income in Shenzhen last year reaching 25,500 yuan, the highest in the country, followed by Beijing and Shanghai. Shenzhen plans to issue a salary guidebook listing average salaries in different occupations, so people working there can better understand their career situation — or perhaps even argue with the boss.
