未知题型 More than three million years ago, our ancestors were already on the march, rising on two legs to search for food, seek greener lands and, above all, to grow in body and brain.

Fossils were found in Ethiopia in 1974. 2. Paranthropus boisei Covered with fur, they had strong arms and gorilla-like faces. They lived 1-2.5 million years ago. Fossils were found in Tanzania in 1959. 3. Homo habilis Homo habilis, which actually means 'handy man', was the first species to make and use primitive stone tools. They lived 1.6-2.2 million years ago. Fossils were found in Tanzania in 1960. 4. Homo erectus With skeletons very similar to those of modern humans, they were probably the first to use fire.

未知题型 Visiting US President George W. Bush said in Beijing on Friday that both China and the United States should encourage bilateral contacts and exchanges to promote mutual understanding. 'It's important for our political leaders to come to China,' said Bush, who gave a speech on Friday morning at Qinghua University, one of the most prestigious universities in China. His working visit to China and discussions with Qinghua students 'help promote' Sine-US relations, Bush said in response to a student's question about what he would do to promote Sine-US relations. 'Many people in my country are very interested in China,' he said, adding that these Americans want to learn more about China's culture and the Chinese people. He said that he would keep encouraging such contacts and exchanges between the two countries. Bush said that he would describe back home what he had seen here and that China as a great nation not only has a 'great history' but also an 'unbelievably exciting future.' The president said that the 2008 Olympic Games would make a significant opportunity for the rest of the world to understand China, which enables more people to come to China and feel the modernization taking place, and many more people will see it on the television.
