Green Roof Research
The concept of green roofs is basically about growing plants on roofs，thus helping to replace the green footprint that had been destroyed due to the construction of the building.Green roofs are the most prevalent(流行)in Germany，which is widely regarded as the leader in green roof research.
The green roofs that are used these days can be classified as "extensive" and “intensive” systems.Extensive green roofs use mosses，grasses and herbs，which are tolerant to droughts. These plants do not need much maintenance，can be grown in a layer of substrate(土层)that can be as shallow as 1.5 inches，and generally are inaccessible to the public.In contrast.a wide range of species of plants are grown on intensive green roofs，such as shrubs(灌木)and even trees，which require deeper substrate layers，and are usually grown on flat roofs.They need intensive maintenance, and are usually areas that resemble parks which are accessible to people.(examda)
There are several benefits of adopting green roof technologies.Apart from the obvious psychological and aesthetic(暮学的)benefits of garden—like environments surrounding you，some of the common‘economic and ecological benefits are：a reduction in the consumption of energy;air and water purification;recovering green spaces;and the mitigation(缓解)of the heat island effect in urban areas.
The green roof research that is currently ongoing is focused on evaluating the species of plants that are suitable to be grown on roofs，the methods of propagation(繁殖) as well as establishment，nutrient(养料)and water requirement，substrates，and the quantity and quality of water runoff.The evaluation criteria of plant species are：at what rate they can be established：their capacity to withstand invasive weeds;tolerance of cold and heat;tolerance of drought conditions;capacity of persistence and survival.
A number of experiments are being conducted on roof platform simulations at various research centers.These sites are generally outfitted with equipment，which are used to measure temperatures at different depths of the growing substrates，and the rate and volume of the runoff of stormwaters from each of the platforms.
Green roof technology is representative of a completely new market for landscape contractors，and all roofs that currently exist and the future ones to be constructed are the potential market—a market that is too huge to be overlooked.
16. It is estimated that around 10 percent of the flat roofs in Germany are green
A.Right B.Wrong C.Not mentioned
17. German people prefer extensive green roof systems to intensive ones
A.Right B.Wrong C.Not mentioned
18. Small plants like grasses and herbs are grown widely on intensive green roofs.
A.Right B.Wrong C.Not mentioned
19. Green roof is an ecologically sound strategy of spreading green in urban areas
A.Right B.Wrong C.Not mentioned(examda)
20. One of the benefits of green roofs is the reduction of the heat island effect in cities
A.Right B.Wrong C.Not mentioned
21. One focus in the green roof research is the evaluation of suitable plant species
A.Right B.Wrong C.Not mentioned
22. Although green roof technology can create a garden—like environment，its potential market is rather small.
A.Right B.Wrong C.Not mentioned

The Supercomputer Network
1 Recently Ten laboratories run by governments in different parts of the world have become linked.Their computers have been connected so they can“talk”to each other. This may not seem very dramatic news，but it is the beginning of a development that will increase the power of the Internet tremendously.
2 The Internet is an interconnected(互联)system of networks that connects computers round the world and facilitates the transmission and exchange of information. The way that you use the Internet is by accessing this network.This depends on the power that your system allows you to use.The power of your computer is responsible for how fast you can download(下载)files，how much data you can store，etc.If your computer is old and slow.accessing the information can be very difficult.
3 The new development in information technology has been called“the grid”(网格技术)，and it will be a network of computers that are linked together.The“grid”will work in a different way from the Internet，enabling you to get the power of the biggest computers in the world on your computer.Accessing the information will no longer depend on the power of your computer.The idea is that while you access information，you will also have access to the power of the bigger computer stations.
4 One advantage of this revolutionary idea is that geographical location will become irrelevant.The“grid”will decide which are the best parts of a worldwide network to do the job you want.This means that you may be accessing a computer In Japan to solve a problem in Alaska.
5 The“grid”can be compared to having an efficient personal assistant.You can give your assistant a task and“he”will do it for you.The assistant will do the preliminary research，c
