Power rationing(拉闸限电）is widening across China.More than 10 provinces     1    （order) power cuts in the past days,including Jiangsu,Zhejiang,Yunnan,and Guangdong.

The country's top economic planner last month flagged nine provinces for the sharp increase in power demand over the first half of the year. That pushed local governments to    2     (strict) order the cuts to avoid missing targets for reducing carbon emission(碳排放）。

In Zhejiang,160 energy-intensive factories have been ordered to stop production    3     (meet) energy consumption targets. The power rationing in Jiangsu also forced factories in the key manufacturing(制造业） industry to cut or even stop their operations     4     the end of the month. Yunnan province is canceling electricity price discounts for some manufacturing factories     5     made power costs about 16-22 percent     6     (cheap) than industry average.

Meanwhile,record-high coal prices are making it unprofitable for many power plants to operate,    7     (create) supply gaps in some provinces.

A number of A-share listed    8     (company) have reported the impacts on stock(股票） exchanges. However, stocks in power suppliers went into    9     crazy rise since the power rationing. Also in Hong Kong, stock prices of the energy industry are    10     (luck) enough to rise by an average of 4.6 percent today, including China Resources Power, China Power Investment and Huaneng Power.

2 . Paper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two important ways. First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.

One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.

Paper is mainly made from cellulose (纤维素)，which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-colored stuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.

Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be developed.

The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industry to do the same. The world will be a better place for it!
