听力原文： Burning fallen leaves used to be standard practice across North America, but (29)most districts now ban or discourage this practice due to the air pollution it causes.
(30) What's more, because of the moisture that is usually trapped within leaves, they tend to bum slowly and thus generate large amounts of particles in the air, such as bits of dust, smoke and other solid materials. These particles can reach deep into lung tissue and cause coughing, chest pain, shortness of breath and other breathing problems.
Individual leaf fires from time to time usually don't cause any major pollution, but multiple fires in one geographic area can cause concentrations of air pollutants that exceed federal air quality standards. According to the U. S. Environmental Protection Agency (EPA), several leaf and yard waste fires burning simultaneously in a particular place can cause air pollution which equals that from factories, motor vehicles and lawn equipment.
(31) On the contrary, leaves can be made fertilizer, which is the most eco-friendly alternative to burning. Dry leaves alone will take a long time to break down, but mixing in green plant materials, such as grass, will speed up the process. Sources of nitrogen, such as livestock wastes or commercial fertilizer, will also help.
Another option is to chop leaves for use as cover for your lawn or to help protect garden and landscape plants. But before you add no more than a two-to-three-inch layer of leaves around actively growing plants, chop the leaves first so they don't prevent air from reaching roots.

听力原文： (26) An elementary school bus driver pulled into a gas station in Ohio because he had to use the bathroom. Instead of turning off the engine and taking the key with him, the driver left the bus running. There were 20 kids on the bus. The driver told a police officer that it was cold outside, and he didn't want the kids to get chilly while he was using the bathroom. But he forgot to set the emergency brake because he was in a hurry.
The bus slowly started rolling away from the gas station. As the bus picked up speed, the kids began yelling and screaming. (27)Ten-year-old Jake ran forward to the driver's seat and grabbed the steering wheel. He pressed hard on the brake pedal and managed to stop the bus as it approached a guard mil overlooking a river. Jake turned off the engine. After the cops arrived at the scene, they congratulated Jake on his heroic effort.
Jake wasn't impressed with what he had done. He thought stopping the bus was easy compared to playing his favorite action video game. The bus driver, walking along the highway when arrested by the police, was initially charged with "leaving a child unattended while motor vehicle is running." While that is only a minor driving violation, the county district attorney said he hoped to upgrade the charge because of the number of children involved.
(28) The district attorney believe that whatever the driver is charged with, the driver will never drive a bus in this county again.

听力原文：W: Well, I'm going to the National Museum of Art.
M: Sure. Hop in.
W: Uh, how long does it take to get there？
M: Well, that all depends on the traffic, but it shouldn't take more than twenty minutes for the average taxi driver.
And I'm not average. I have been driving down to an art, so we should be able to cruise through traffic and get there in less than twelve minutes.
W: Okay. Uh, sorry for asking, but do you have any idea how much the fare will be？
M: Oh, it shouldn't be more than 18 dollars.., not including a... uh-hum... a tip of course.
W: Oh, and by the way, do you know what time the museum closes？
M: Well, I would guess around 6:00 o'clock. And it's 4:30 now. Uh, this is your first time to the city, right？
W: Yeah. How did you know？
M: Well, (19)you can tell tourists from a mile away in this city because they walk down the street looking straight up at the skyscrapers.
W: Was it that obvious？
M: Well...
W: Oh, before I forget, can you recommend any good restaurants downtown that offer meals at a reasonable price？
M: Well, (20) the Mexican restaurant, La Fajita, is fantastic. It's not as inexpensive as other places I know, but the environment is quite pleasing, and the portions are larger than most places I've been to.
W: Sounds great! How do I get there from the museum？
M: Well, you can catch the subway right outside the museum. There are buses that run that way, but you would have to transfer a couple of times. And there are taxis too, but they don't run by the museum that often. (21) So I strongly recommend you to take the subway.
W: (21)Thanks for your advice.
