It all starts with a tree．In fact, it starts with several trees．Since the first modern guitars were made in northern Spain over 150 years ago, crafts persons have known the wood to be used is important in making a guitar.

Every guitar is made of several different kinds of wood．Each piece is carefully chosen and then cut to fit the part of the guitar for which it is designed．The most important part of a guitar is the soundboard--the piece of wood with a large hole that lies under the strings(弦,线)．Guitar makers are careful to make the soundboard just the right shape and thickness．Then they fix stripes（长条）of wood across the inside in a special pattern, which helps strengthen the soundboard and improves the tone of the guitar.

Wood for the curvy (弯曲的) sides of the guitar must be soaked (浸湿) in water and bent over a hot iron pipe．When all the pieces of the guitar are ready, they are carefully stuck together with glue．Special woodworking tools are used to shape and smooth the neck of the guitar．The craftsperson must make sure that the neck is perfectly centered over the soundboard.

Then it is time to use varnish(亮光漆)．This brings out the beauty of the wood．Varnish also improves the sound of the guitar but too much varnish makes the guitar sound flat and dull.

Finally guitar strings are attached and tightened to make just the right musical tones．Then it’s time to play a song．(273 words)

A great French writer has said that we should help everyone as much as we can because we often need help ourselves. The small even can help the great. About this, he told the following story.

An ant was drinking at a small river and fell in. she tried her best to reach the side, but she couldn’t move at all. The poor ant got too tired but was still doing her best when a big bird saw her. With a pity, the bird threw a piece of wood. With it the ant reached the bank again. While she was resting and drying herself in grass she heard a man coming up. He was walking without shoes on his feet and carrying a gun in his hand. As soon as he saw the bird, he wished to kill her, and he would certainly do so, but the ant bit(咬) him in one of his feet and at that moment the bird flew away at once. It was an animal much weaker and smaller than the bird herself that had saved her life.

Plastic is one of the most important technological discoveries of the 20th century. However, it may soon be replaced. The new development- liquid wood- can replace plastics in all branches of modern-day industries.

Plastic as a material enjoys the biggest demand in the modern world, but it does have a number of drawbacks. First and foremost, plastic isn’t recyclable. Secondly, it contains toxins (毒物) helping develop cancerous diseases. Finally, it’s made of oil and oil reserves aren’t endless.

The liquid wood technology is likely to replace plastic and providing mankind with new materials for many years ahead. Norbert Eisenfreich, a senior researcher at the Faunhofer Institute for Chemical Technology in Germany (ICT), said that arboform, the new material, is made of lignin(木素质）, which can be obtained from soft tissues of wood. Once mixed with several other matenals, it turns into solid and non-toxic alternative for plastics.

ICT team leader Emilia Regina Inone-Kauffmann said the wood-working industry separates wood into three basic components, including lignin. Lignin isn’t used for the production of paper. Specialists of ICT mixed lignin with several natural materials and thus invented the material which could be melted and molded (铸型）.

When solid, arboform looks like plastic and possesses tho qualitie of polished wood. It can be used for the production of any items. Arboform is already used for the production of car parts which require extra strength. In addition, liquid wood can be recycled repeatedly. The material preserved all of its qualities even if it’s reprocessed ten times.

However, the new invention doesn’t enjoy an extensive use due to the high content of sulfur(硫) in it. German researchers are sure to reduce the amount of sulfur by 90% very soon to make arboform usable for home needs.

71. According to the passage, plastic        .

A. helps us to reduce the use of petrol

B. helps to protect our environment in some way

C. does harm to our society in some way

D. has been replaced by the newly discovered material

72. What’s the advantage of arboform over plastic?

A. It is easier made from natural oil.

B. It is more widely used in household

C. It is recyclable and friendly to environment.

D. It contains no poisonous materials.

73. The underlined word “altemative” in Paragraph 3 means        .

A. lignin or arboform                                B.soft tissues of wood

C. plastics or wood                                    D. mixture of several materials

74. It can be concluded that German researchers will focus their future work firstly on     .

A. the material’s extensive use                    B. the content of sulfur in arboform

C. the production cost of arboform                     D. the qualities of liquid wood

75. The main purpose of the text is to     .

A.introduce liquid wood which will replace plastic

B.show readers how to produce arboform

C.advertise the new material-arboform

D.advertise new products made of arboform
