第2题
听力原文： In Washington, President Bush said again, Wednesday US forces will remain in Iraq until it's free country run by the Iraqi people. And in Iraq, British Foreign Secretary Jack Straw said attacks on united forces will not succeed in getting those forces to leave the country before security is established. Bush administration officials say the White House may make a decision shortly on sending US peacekeeping troops as part of a multi-national peacekeeping force to help end Liberia's deadly civil war. Washington has come under intense international presure to do something about the fighting which killed hundreds of civilians in Liberia's capital last week. White House spokesman says there are indications that the Bush administration would like to settle the issue before the President leaves Monday on a 5-day African tour. Mr. Bush expressed concern for the suffering of the Liberian people Wednesday and again called for Librian President Charles Taylor to step down in the interest of peace. In Liberia, President Taylor signaled a willingness to leave, but to leave on terms, on his schedule.
President Bush said US forces will remain in Iraq until ______.
A．It's a free country run by UN
B．It's a colony run by US
C．It's a free land run by its own people

Fossil charcoals tell us that wildfires have been part of life on the earth for as long as there have been plants on land. Fire was here long before such plants as grasses; it predated the first flowers. And without wanting to get mystical about it, fire is ,in many respects , a kind of animal, albeit an ethereal one .Like any animal, it consumes oxygen .Like a sheep, it eats plants. Sometimes, it merely nibbles a few leaves; sometimes it kills grown trees. Sometimes it is more deadly and destructive than a swarm of locusts.
The shape-shifting nature of fire makes it hard to study. Some fires are infernally hot; others, relatively cool. Some stay at ground level; others climb trees. Moreover, fire is much more likely to appear in some parts of the world than in others. Satellite images of the earth show that wildfires are rare in, say, Northern Europe, and common in parts of Central Africa and Australia.
Once a fire gets started, many factors contribute to how it will behave. The weather obviously has a huge effect: winds can fan flames, rains can quench them. The lie of the land matters, too: fire runs uphill more readily than it goes down. But another crucial factor is what type of plants the fire has to eat.
It’s common knowledge that plants regularly exposed to fire tend to have features that help them cope with it, such as thick bark, or seeds that only grow after being exposed to intense heat or smoke.

What Are Tropical Storms？
Severe storms spawned in the tropics are known by different names in different parts of the world: hurricanes in the Atlantic and east Pacific and typhoons in the northwest Pacific and cyclones in the southwest Pacific and Indian Ocean. These storms originate over tropical waters, close to the equator. If the atmosphere is calm and the water is warmer than about 27℃, evaporation forces large amounts of moisture into the air, creating a low-pressure system. When this water vapor condenses, it releases heat that powers the circular winds that characterize these storms.
Rainfall in the developing storm releases more heat, triggering a convection process that pulls more moisture-laden air up through the centre of the system. The storm grows via this feedback mechanism. The strongest winds are found immediately outside the centre, or "eye", of the hurricane at ground level.
Every one of these systems begins as a tropical depression—a system of thunderstorms with an overall circular motion and maximum sustained winds less than 62 km/h. When a storm becomes severe enough and the winds pick up to more than 62 km/h, it is designated a tropical storm. When the winds reach 119 km/h, the system is called a hurricane, typhoon or cyclone.
An average of 10 tropical storms develop over the Atlantic Ocean each year, of which about six become severe enough to be called hurricanes. Besides strong winds and heavy rain, these hurricanes also create a "storm surge", a massive wave beneath the centre of the storm. In the eye of the hurricane, air is sucked upward faster than it can rush in at the bottom. This lowers the atmospheric pressure under the eye of the storm; as a result, the eye tries to pull at the ocean itself, creating a bulge of water as much as six metres high that moves together with the storm.
When is the hurricane season？
Hurricane season officially runs from June I to November 30, but the most intense storms mainly occur between mid-August and mid-October.
How are hurricanes classified？
Tropical storms that get strong enough to be classified as hurricanes are categorized by the intensity of their wind speeds using the Saffir-Simpson scale. Only three Category 5 hurricanes have made landfall in the U.S. in the past century—one that struck the Florida Keys in 1935, Hurricane Camille in 1969, and Hurricane Andrew in 1992. How are tropical storms named？
A tropical storm is given a name if its winds reach a speed of 62 kilometres per hour. An international committee has drawn up a list of 126 names—half male and half female—which are repeated after a six-year cycle. However, if a hurricane causes extensive damage, its name is retired from use. So far, more than 50 names have been retired, from Hazel in 1954 to Juan in 2003.
Memorable hurricanes
In August and September 1992, Hurricane Andrew wrought havoc across the Caribbean and Florida. Andrew was an unusual storm—after brewing for several days at low latitudes, it weakened and nearly vanished about 600 km east of Puerto Rico. But the storm regained its strength and moved northward with devastating results. Andrew left 17,000 people homeless in Florida alone and destroyed or badly damaged 85,000 homes. The storm caused a record $26.5 billion in property damage. In 2002 Andrew, initially classified a Force 4, was upgraded to have actually been a Force 5 storm.
In November 1998, Hurricane Mitch tore through Central America, killing as many as 10, 000 people and leaving two million homeless in Nicaragua and Honduras. The storm's 300 km/h winds and heavy rains caused more than $3 billion in damage—more than half the combined gross domestic product of those two countries. Mitch also unleashed deadly landslides, and caused the worst flooding in the region in 200 years. In the storm's wake, with roads and infrastructure
