Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems.
Experts say green roofs usually do not get much above 27℃. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water.
Earlier in 2008, researchers in Texas reported that green roofs can reduce a building's air conditioning costs by about onefifth compared to blacktop roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated (隔热的) boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs. Each rooftop had sixteen different kinds of plants native to Texas. The researchers say the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs. The native plants could take in more water and release more of it to the atmosphere.

3 . The Sieferts are the kind of environmentally conscious family who has solar panels atop their home. They use timers on their kids' showers and have planted drought-tolerant landscaping. But they feel kind of guilt. “I haven’t thought about the pool as much as I probably should,” said Annette Siefert.
As California's drought worsens, swimming pools have become a target for those who think the classic backyard greens waste water. Some water districts have banned new pools from being filled and have limited how much water existing pools can use.
But some of those agencies are walking back the rules as they make a surprising discovery: Pools aren't the water wasters some have made them out to be. Analyses by various water districts, along with scientific studies, conclude that pools and their surrounding landscapes use about the same amount of water as a lawn(草坪) of the same size. Over time, pools might even use less water. With pool covers, experts say water evaporation(蒸发)can be cut by almost half, making pools significantly less wasteful than grass and about as efficient as drought-tolerant landscaping.
Facing complaints over a recent ban on filling pools, the Santa Margarita Water District conducted its own water-use analysis. It found that pools require thousands of gallons of water to fill initially, but they use about 8,000 gallons less water than a traditional landscape after that. By the third year, the analysis found, the savings add up, and a pool's cumulative water use falls below that of a lawn.
Water agencies such as the Los Angeles Department of Water and Power have come to similar conclusions. Armed with new information, Santa Margarita Water District officials will reconsider their ban next week.
“We want to respect the people's rights to use their property. There are many families we know that have saved for pools,” said Jonathan Volzke, spokesman for the 155,000-customer district. “But at the same time, the reality around us is that we're in the third year of a serious drought, and we don't know if we're in the third year of a three-year drought or the third year of a 10-year drought.”

4 . Four days after Dad’s 67th birthday, he had a heart attack. Luckily, he survived. But something inside him had died. His enthusiasm for life was gone. He refused to follow doctor’s orders, and his sour attitude made everyone upset when they visited him. Dad was left alone.
So I asked Dad to come to live with me on my small farm, hoping the fresh air would help him adjust. Within a week after he moved in, I regretted the invitation. He criticized everything I did. I became frustrated. Something had to be done.
One day I read an article which said when given dogs, depressed patients would be better off. So I drove to the animal shelter that afternoon. As soon as I got there, a pointer’s eyes caught my attention. They watched me calmly.
A staff member said: “He got here two weeks ago and we’ve heard nothing. His time is up tomorrow.”
I turned to the man in horror. “You mean you’re going to kill him”
“Ma’am,” he said gently. “We don’t have room for every unclaimed dog.”
The police’s calm brown eyes awaited my decision. “I’ll take him,” I said.
I drove home with the dog on the front seat beside me. I was helping it out of the car when Dad walked onto the front porch. “Look what I got you!” I said excitedly.
Dad wrinkled his face. “I don’t want it,” he muttered, turning back towards the house. Then, suddenly, the dog pulled free from my grasp. He sat down in front of my Dad.
Dad’s anger melted, and soon he was hugging the dog.
This was the beginning of a warm friendship. Dad named the dog Cheyenne. Together they spent long hours walking down dusty lanes and relaxing on the banks of streams.
Dad’s bitterness faded, and he and Cheyenne went on to make many friends. Then, late one night two years later, I felt Cheyenne’s cold nose burrowing (搜寻) through my bed covers. He had never before come into my bedroom at night. I ran into my father’s room and found that he had passed away.
Two days later, my shock and grief deepened when I discovered Cheyenne lying dead beside Dad’s bed. As I buried him near their favorite stream, I silently thanked the dog for restoring Dad’s peace of mind.

Her owner Mike Holden panicked and celled the coastguard of Cornwall, who turned up in seconds . Six volunteers slid down the cliff with the help of a rope but gave up all hope of finding her alive after a 90-minute search.
Three days later, a hurricane hit the coast near Cornwall. Mr. Holden returned home from his holiday upset and convinced his pet was dead. He comforted himself with the thought she had died in the most beautiful part of the country.
For the next two weeks, the Holdens were heartbroken . Then, one day, the phone rang and Steve Tregear, the coastguard of Cornwall, asked Holder if he would like his dog bark.
A birdwatcher, armed with a telescope, found the pet sitting desperately on a rock. While he sounded the alarm, a student from Leeds climbed down the cliff to collect Judy.
The dog had initially been knocked unconscious(失去知觉的)but had survived by drinking water from a fresh scream at the base of the cliff. She may have fed on the body of a sheep which had also fallen over the edge. “The dog was very thin and hungry,” Steve Tregear said , “It was a very lucky dog. She survived because of a plentiful supply of fresh water,” he added.
It was ,as Mr. Holden admitted, “a minor miracle(奇迹)”.

The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.
On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.
On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.
Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.
It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.
1. What can we learn about full-sun coffee production from Paragraph 4?
A.It limits the spread of new growing techniques. |
B.It leads to air pollution and global warming. |
C.It slows down the loss of shade trees. |

8 . In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.
Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains.
In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development.
Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of growing population within the limits if this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

9 . Around the world there is an increase in the demand for reforestation. This is because the consumption of the forests has affected not only the animals living in the area but also the people. And reforestation is about the rebuilding of the forests that have been severely destroyed. It can offer a lot of benefits when the recreation is successful.
Destroying a forest is easy but rebuilding it is really hard.
The forest greatly helps in the reduction of the air pollution. Trees are responsible for the production of oxygen and absorption of carbon dioxide.
There cannot be a better way to restore the balance of nature than to increase the forest area. We must remember that the forest is a natural habitat of wide variety of animals and plants. In this manner, there is no substitute for reforestation.
A.And global warming will speed up the destruction of forests. |
B.Keep in mind that you can’t just plant the seedlings anywhere. |
C.Recreations won’t work until all these details have been considered. |
D.So a good plan is needed to make the reforestation a successful one. |
E.The forest also protects us from typhoons and other natural disasters. |
F.There are many things to be done when it comes to this type of effort. |
G.It is important to make sure that they are suited to the climate and the type of soil. |
