Hannibal was a general from Carthage, a city on the northern coast of Africa. He thought the ancient Romans and won great battles at a time when the Romans were the most powerful people in the world. His army was small, but it was made up of soldiers from many countries that didn't want to be ruled by the Romans.

Before Hannibal could fight the Romans always had thought would protect them from enemy armies. When winter came, the Romans did not think Hannibal could possibly cross the mountains. Hannibal surprised them. With some of his soldiers riding huge strong elephants—where no elephants had to walk slowly without resting through the mountain snow-storms and howling(怒号)winds. The enemies rolled rocks down to try to stop them. Even raging rivers couldn't stop them. Hannibal's soldiers built rafts(木排)strong enough to carry the elephants across. At last, half of them never reached the end of their journey. But the other half of the army and some of the elephants did finish the journey.

Mayor Boris Johnson Monday outlined plans to make London “the cleanest，greenest city on Earth” by the 2012 Olympics and called for commitments from other world cities at a climate change conference.Leaders of the world's 40 largest cities are meeting in Seoul this week for a summit on combating global warming — the third to be held since 2005.

“What we should do in Seoul is agree that we will stop the endless addiction of mankind to the internal combustion engine (内燃机)，”said Johnson.He said at a press conference the world's cities consume 75 percent of the world's energy and produce 80 percent of the emissions which cause climate change.“The problem of our planet is an urban problem，” Johnson said.

    He said the British capital wants to use the Olympics “to drive the greening and the improvement of our city” and noted that London is committed to reduce carbon dioxide emissions by 60 percent by 2025.

    Johnson said the key measure was being taken to solve problems relating to housing and commercial buildings，which accounted for 70 percent of carbon dioxide emissions in London.This involved retrofitting (翻新)—installing lagging—in large numbers of public buildings.

    Johnson proclaimed himself a“passionate cyclist”and said he would push ahead with cycle superhighways around London.

London's air quality problem，he said，was caused by vehicle emissions from 8,300 worn and used diesel (柴油) buses，which could be replaced by low-carbon vehicles.In addition，there were also 32,000 taxis running on diesel fuel，which could be replaced by electric vehicles.

   Johnson said there would be a few programs in the next few years to produce a “cleaner，greener” bus for the city.“The age of the diesel bus has got to be over in London.”
