Xuan paper, known as one of the Four Treasures of Study, first came into    1     (exist) in Xuan Prefecture in the Tang Dynasty. The traditional skill of making the paper     2     hand has been passed down through generations. The process takes as many as 108 steps, all of     3     require a level of delicacy.

Take papermaking master Zhou Donghong, for example. He uses a fine screen to filter (过滤) a mixture of water and fibers. He lifts it up, and it’s a sheet of paper. It takes him and his partner only 15 seconds     4     (form) and shape it, but they’ve devoted     5     (they) to perfecting the skills for decades.

“There are a lot of tricks of filtering the fibers, and timing is the    6     (difficult) part of all. We have only one chance to filter the right amount of fibers, and only the proper weight guarantees the paper is neither too thin nor too thick, and the margin (差额) for error is     7     (extreme ) small,” said Zhou. With just the right degree of thickness, top quality Xuan paper holds ink tightly.

The skill of papermaking,    8     (recognize) as a national treasure, has also proven to be an international one. We felt     9     great sense of pride as it     10     (list) as a world intangible culture heritage (非物质文化遗产) by UNESCO in 2009. Since then, in Jingxian County, Xuan papermaking has been taught in schools.

I am not a brave girl     1     I’ve been crazy about bungee jumping(蹦极). One day, I found a good place for this exciting sport in Thailand by     2     (surf) the Internet. I packed my bag and     3     (fly) there. Having bought some bread, I had to wait for the car     4     was supposed to pick me up. At last a young man drove me to the bungee jumping place. I was amazed by the     5     (sight) along the road. There I signed     6     agreement and put on a harness(安全带). The guide led me through a gate, asked me to sit in a special seat and tied my legs and ankles well. As soon as I stood up and felt my ankles     7     (tie) together, I got frightened. I walked slowly to the edge of the bridge and     8     (look) back. The workers looked at me and couldn’t help     9     (laugh). At last it was time to go. My memory seemed to stop.I felt myself going up, like riding a fast lift，and then another drop...Finally, I stopped in the air.I spread my arms wide, laughing loudly and     10     (proud). The workers pulled me up, smiling at me.

On May 18, it was announced that China     1     (achieve) success in drilling fire ice, a frozen mixture of water and natural gas, from the South China Sea.     2     (official) known as methane hydrates (甲烷水合物), fire ice produces a high amount of energy when it is burnt and its chemical reaction produces nothing but dioxide and water.

Fire ice, both clean and energy-intensive,     3     (consider) the fuel of the future. But, the Chinese team succeeded in     4     (extract) fire ice for nearly eight successive days, which is a big breakthrough. However, it is too early     5     (say) a new energy source has been found. The worlds total fire ice reserve is about 21,000 trillion cubic meters，    6    , if extracted, could meet the worlds energy need for 1,000 years. But the    7     (success) test drilling of fire ice does not mean it can be extracted for     8     (industry) use. China has to solve many problems     9     it can use fire ice as a source of energy.

It’s thought that only by 2025 at     10     earliest might people be able to look at realistic commercial options.

There comes a time when the old must give way to the new. Finding and     1     (keep) the right balance between progress and the protection of cultural sites can be     2     big challenge.

In the 1950s, the Egyptian government wanted to build a new dam across the Nile     3     (control) floods, produce electricity and supply water to more farmers, but the proposal led to     4     (protest).

After listening to the experts’ opinion, the government turned to the United Nations for help. Then a committee     5     (establish) to limit damage to the Egyptian buildings and prevent the loss of cultural relics.     6     (final), a document was signed, and the work     7     (begin) in 1960.

    8     the project ended in 1980, it was considered a great success. Not only had the countries found a path     9     the future that did not run over the relics of the past, but they had also learnt that it was possible for countries to work together to build a better tomorrow. The spirit of the Aswan Dam project is still alive today.   If a problem seems too difficult for a single nation, the     10     (globe) community can sometimes provide a solution.

He lay down on the bed and fell fast asleep. When he woke up the next morning,     1     unknown hand had placed a cup of hot coffee and some fruits by his bedside.   

The man had breakfast and after tidying     2     (he) up, went downstairs to thank the generous host. But, as on the evening before, there was nobody     3     sight. Shaking his head in wonder at the strangeness of it all, he went towards the garden     4     he had left his horse, tied to a tree.     5     (sudden) a large rose bush caught his eye.   

Remembering he promised he    6     (bring) a rose to Beauty, he bent down to pick a rose. At once, out of the rose garden, rose up a horrible beast,     7     (wear) splendid clothes. A deep, terrifying voice growled (吼), “Ungrateful man! I gave you a place to stay at for the night, you ate at my table and slept in my own bed,     8     now all the thanks I get is that one of my favourite flowers     9     (pick) by you! I shall put you to death for this!” Trembling with fear, the man fell on his    10     (knee) before the Beast.

Ryan’s charity work is not unusual. Many kind-hearted people who give Ryan much support donate money for charity     1     (activity), and others volunteer to help run charities. On most UK high streets, for instance, you will often come across people    2     (raise) money and looking for volunteers for Cancer Research UK, the British Heart Foundation and many     3    (much), one of     4     many public-spirited citizens are willing to take an active part in.     5     the help of the organizations, the poor or the     6     (disable) can improve their lives or even realize their dreams.

In china, volunteers are also playing an    7     (increasing) important role in environment protection, disability    8     (assist) and many other fields.
