ng 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.

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
