听力原文： American researchers say cutting down trees in snow regions might help counter the effects of global warming. The findings highlight the complexity of the planet as it'd previously been understood that mass deforestation contributed to global warming. It's been a woe cry for environmentalists in recent years "Mass deforestation contributes to global warming." But that argument may now have to be revised. Scientists in the United States have run a simulation of the effects of large-scale clearing. And they find that if trees were to be cut down in the icy northern regions, it would actually cool down the Earth. The reason: snow reflects sunlight and the great pine forests of Russia, Europe and Canada shade tens of thousands of hectares of reflective snow.
What might help control global warming according to American researchers？

A million motorists leave their cars filled up with petrol and with the keys in the ignition every day. The vehicles are sitting in petrol stations while drivers pay for their fuel. The Automobile Association (AA) has discovered that cars are left unattended for an average three minutes—and sometimes considerably longer—as drivers buy drinks, sweets, cigarettes and other consumer items—and then pay at the cash till. With payment by credit card more and more common, it is not unusual for a driver to be out of his car for as long as six minutes, providing the car thief with a golden opportunity.
In an exclusive AA survey, carried out at a busy garage on a main road out of London, 300 motorists were questioned over three days of the holiday period. Twenty four percent admitted that they "always" or "sometimes" leave the keys in their cars. This means that nationwide, a million cars daily become easy targets for the opportunist thief.
For more than ten years there has been a bigger rise in car crime than in most other types of crime. An average of more than two cars a minute are broken into, vandalized or stolen in the UK. Car crime accounts for almost a third of all reported offences with no signs that the trend is slowing down.
Although there are highly professional criminals involved in car theft, almost 90 percent of car crime is committed by the opportunist. Amateur thieves are aided by our own carelessness. When AA engineers surveyed on town center car park last year, ten percent of the cars checked were unlocked, a figure backed by a Home Office national survey that found 12 percent of drivers sometimes left their cars unlocked. The AA recommends locking up whenever you leave the car—and for however short a period. A partially open sun-roof or window is a further come-on to thieves.
There are many other traps to avoid. The Home Office has found little awareness among drivers about safe parking. Most motorists questioned made no efforts to avoid parking in quiet spots away from street lights—just the places thieves love. The AA advises drivers to park in places with people around—thieves don't like audiences. Leaving valuables in view is an invitation to the criminals. A Manchester probationary service research project, which interviewed almost 100 car thieves last year, found many would investigate a coat thrown on a seat. Never leave any documents showing your home address in the car. If you have a garage, use it and lock it—a garaged car is at substantially less risk.

SECTION A CONVERSATIONS
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文：W: Dad !
M: Uh, what？
W: The movie is over. You slept through the best part.
M: Ah, I must have dozed off during the last few minutes.
W: Right. You were gone for so long you should have brought your pillow and blanket. So, what did you think about it？
M: Well, overall, I'm a little disappointed with the movie. I mean, the story was a little bizarre, you have to admit. I mean, really. How believable is a plot about a captain who navigates his spaceship to the far reaches of the galaxy and encounters a race of frog people. I mean, come on.
W: Ah, I thought it was fantastic. I mean, you have to admit that the special effects were awesome, and the acting wasn't had either.
M: Ah, come on. What about the ship's communications officer？ I mean, what did you think about him？ Well... Wasn't he a little weird to you？ He was always talking to himself, and he had that funny hairdo？
W: Well, he was a little unusual, but the ship's doctor was amazing. It was so cool when he brought the captain back to life during one of the battles.
M: That was pretty realistic, but then the rest of the movie just went from bad to worse. And the photography was so fake!
W: How do you know？ You were snoring so loud the neighbors probably had to close their windows. It was that bad. M: Ah, well, let's go to bed.
What is one word to describe the father's opinion about the movie's storyline？
First, decide if you want an upright or chest model. Uprights are more convenient. Their storage space is more accessible and they take up less floor area. However, chest models are more energy-efficient because less cold air escapes when they are open.
If you're buying an upright, you'll have to choose between frostless or manual defrost. Chest freezers are always manual. Frostless freezers automatically defrost at preset intervals and remove the water. Manual models must be defrosted by hand every few months or whenever frost accumulates to about a quarter of an inch.
To help your freezer reach a ripe old age, try to find a spot that's cool, dry, and away from drafts. Drafts and heat will raise the freezer's cabinet temperature and make it work harder to keep cool. That means wasted energy and a shortened compressor life.
Dry air is important because high humidity can cause the freezer to rust outside and frost up inside. With proper care, a freezer can serve you for 15 years or more.
Frostless models require less care than manual defrost freezers. The interior of a frostless unit should be washed periodically with warm water and baking soda or a mild soap, rinsed, and dried.
To get the most from your freezer, check regularly to make sure it's providing a true zero-degree temperature.
Keep the freezer at least three-quarters full. The emptier it gets, the more energy is wasted. If more than three pounds of food per cubic foot of storage space is added every 24 hours, the resulting high or low temperatures can damage the food.
According to the passage, choosing the best place for your freezer means______。
