At a few minutes past five, Dave noted that the blanket of darkness was lifting. He was just able to make out the heavier masses that eventually appeared as the familiar trees that lined the road at the base of the hill. The upper reaches of the sky showed lighter shades of gray.
Dave got out of bed quietly and dressed quickly. He mixed a spoonful of instant chocolate into a glass of cold water, and his impatience forced him to finish the drink in gulps.
As he walked down toward the lake, Dave paused to reach for the fishing pole and gear box on the bench where he had left them the night before.
By the time he reached the small boat, a thick white mist (雾气) had spread over the surface of the water. He stepped into the boat, sat down, and rowed out of the weed beds that lined the edge of the shore.
The outer fringe (边缘) of the lake disappeared as the boat moved forward noiselessly. All he could see was the enveloping whiteness. He could not tell where the boat and the surrounding air met the surface of the lake.
Dave rowed steadily ahead, relying on a mental picture of the surroundings. Then the mist began to rise, slowly. It soon rested inches above the still surface of the lake. The heavy silence was now being broken by the fish breaking through the surface as they leaped out of the water for low-flying insects.
The magic time had arrived. Dave raised his pole. Dawn was broken. He was excited with expectancy.

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧） levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.According to the new findings, taking steps to prevent northern forest fires may __________.
| A．result in a warming climate |
| B．cause the forest fires to occur more frequently |
| C．lead to a longer fire season |
| D．protect the forests and the environment there |
The following are all the immediate effects after a forest fire EXCEPT __________.
| A．large amounts of greenhouse gases enter the atmosphere |
| B．the levels of ozone which is a type of oxygen increase |
| C．snow on the ground mirrors more sunlight back into space |
| D．ashes from the fire fall on the ice surface and take in more radiation from the sun |
Earlier studies about northern forest fires __________.
| A．analyze all aspects of how northern fires influence climate |
| B．indicate that forest fires will pollute the atmosphere |
| C．suggest that people should take measures to protect environment |
| D．suggest that the fires will speed up climate warming |
The underlined phrase “soak up” in the last paragraph most probably means __________.
| A．released | B．absorbed | C．created | D．distributed |
From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may __________.
| A．warm the climate as the supposition goes |
| B．allow more snow to reflect more sunlight into space and thus cool the climate |
| C．destroy large areas of forests and pollute the far-off sea ice |
| D．help to gain more energy rather than release more energy |
A little under one-third of U.S. families have no Internet access and do not plan to get it, with most of the holdouts seeing little use for it in their lives, according to a survey released on Friday.
Park Associates, a Dallas-based technology market research firm, said 29 percent of U.S. families, or 31 million homes, do not have Internet access and do not intend to subscribe（预订） to an Internet service over the next 12 months. The second annual National Technology Scan conducted by Park found that the main reason why potential customers say they do not subscribe to the Internet is because of the low value to their daily lives rather than concerns over cost.
Forty-four percent of these families say they are not interested in anything on the Internet, versus just 22 percent who say they cannot afford a computer or the cost of Internet service, the survey showed. The answer "I'm not sure how to use the Internet" came from 17 percent of participants who do not subscribe. The response "I do all my e-commerce shopping and YouTube-watching at work" was cited by 14 percent of Internet-access refuseniks. Three percent said the Internet doesn't reach their homes.
The study found U.S. broadband adoption grew to 52 percent over 2006, up from 42 percent in 2005. Roughly half of new subscribers converted（转变） from slower-speed, dial-up Internet access while the other half of families had no prior access.
"The industry continues to chip （击破）away at the core of non-subscribers, but has a long way to go," said John Barrett, director of research at Parks Associates. "Entertainment applications will be the key. If anything will pull in the holdouts, it's
going to be applications that make the Internet more similar to pay-TV," he predicted.What does the underlined word “holdouts” in the first paragraph most probably mean?
| A．some American families |
| B．those who hold out one’s opinions |
| C．those who have been surveyed |
| D．those who still haven’t access to the Internet currently |
Many potential customers refuse to subscribe to the Internet mainly because __________.
| A．they show too much concern about the cost |
| B．they can find little value of it |
| C．they do most YouTube-watching at work |
| D．the Internet doesn’t reach their homes |
From the passage we can infer that _____________.
| A．It is not an easy job to transform those holdouts into the Internet users |
| B．people will adopt dial-up Internet access no more |
| C．many Americans enjoy doing e-commerce shopping at home |
| D．more than half of the population are using the Internet in 2005 |
According to John Barrett, what is the key to attracting more U.S. families to broadband service?
| A．making the Internet look more similar to TV set |
| B．applying the Internet more to entertainment |
| C．providing more pay-TV programs |
| D．chipping away at the core of non-subscribers |
Which is the best title for the passage?
| A．Web develops with technology |
| B．The present situation of web |
| C．Many Americans see little point to web |
| D．It is urgent to promote web service |
We have met the enemy and he is ours We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest suddenly turns up in children in the American .Midwest it's hard not to wonder of the disease that comes from foreign animals is homing in on human beings. "Most of the infections （感染）we think of as human infections started in other animals" says Stephen Morse director of the Center for Public Health Preparedness at Columbia University.
It's not just that we're going to where the animals are; we're also bringing them closer to us Popular foreign pets have brought a whole new disease to this country A strange illness killed Isaksen's pets and she now thinks that keeping foreign pets is a bad idea "I don't think it's fair to have them as pets when we have such a limited knowledge of them "says Isaksen.
"Laws allowing these animals to be brought in from deep forest areas without stricter control need changing"says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their owners. We know very little about these new diseases A new bug（病毒）may be kind at first. But it may develop into something harmful（有害的）Monkey-pox doesn't look a major infectious disease But is not impossible to pass the disease from person to person.

It’s not easy being a teenager（13至19岁青少年）—nor is it easy being the parent of a teenager. You can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important to give your child the space he needs to grow while gently letting him know that you you’ll still be there for him when he needs you.
Expect a lot from your child, just not everything.Except for health and safety problems, such as drug use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something, don’t insist he tell you what’s on his mind. The more you insist, the more likely that he’ll clarn up. Instead , let him attempt to solve（解决）things by himself. At the same time, remind him that you’re always there for him should he seek advice or help. Show respect for your teenager’s privacy （隐私）. Never read him his mail or listen in on personal conversions.
Teach your teenager that the family phone is for the whole family. If your child talks on the family’s telephone for too long, tell him he can talk for15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation（节制）. Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part –time jobThe main purpose of the text is to tell parents _____________.
