第二部分：阅读理解(共两节，满分40分)
第一节:共15小题，每小题2分，满分30分
A
Plastic is one of the most important technological discoveries of the 20th century. However, German scientists are certain that this material may soon be replaced. The new development-liquid wood-can replace plastics in all branches of modern industries.
Plastic as a material enjoys the biggest demand in the modem world, but it does have a number of disadvantages. First, plastic is not recyclable. Second, it contains poisons that can cause cancer. Finally, plastic is made of oil, which is not endless. The liquid wood technology is able to replace plastic and providing mankind with new materials for marry years ahead. Arboforn is a new material, which can be got from soft tissues(组织) of wood. Once mixed with several other ingredients(成分), it turns into solid and non-poisonous material.
The wood -working industry separates wood into three basic things including lignin(木质素), which is not used for the production of paper. Specialists of the Faunhofer Institute mixed lignin with several natural materials and thus invented the material which could be melted and moulded(铸造).
When solid arboform looks like plastic and possesses the qualities of wood, it can be used for the production of any items.
Arboform is already used for the production of car parts. However, the new invention does not enjoy a wide use due to the high content of sulphur(硫) in it. German researchers believe that they will be able to reduce the amount of sulphur by 90 percent very soon to make arboform usable for home needs.
In addition, liquid wood can be recycled repeatedly. The analysis of arboform showed that the material had all of its qualities even if it was reprocessed ten times.
21. From the passage we learn that liquid wood________
A. has replaced plastic
B. is made from natural oil
C. has been widely used in household
D. can be recycled repeatedly
22. It can be concluded that German researchers will focus their future work firstly on
the__________
A. material's wide use
B. content of sulphur in arboform
C. production cost of arboform
D. qualities of liquid wood
23. Which of the following is NOT true?
A. Lignin contains poisons that can cause cancer.
B. Plastic does harm to our society in many ways.
C. The liquid wood helps to protect our environment
D. Arboform isn't usable for home need at present.
24. The best title of the passage should be__________
A. Plastic Has a Number of Disadvantages
B. A New Material-Plastic
C. Liquid Wood to Replace Plastic
D. How to Protect Arboform
B
Blue-eyed people have been living in Europe for at least 7,000 years, scientists have
discovered.
A man who lived on the Iberian Peninsula before Europeans became farmers probably had blue eyes but dark hair and skin, according to scientists who have sequenced (按
序排列 ) his DNA. This surprising combination of eye, hair and skin coloring may not have been unusual during his lifetime, but it is no longer seen among modern Europeans, reported by the journal Nature.
The man, a Neolithic hunter-gatherer known to scientists as La Brana 1, is of great interest to scientists because he offers a snapshot of what was in Europeans' DNA before agriculture (农业)spread through the continent. Experts have understood that certain genetic(基因的)feature spread quickly among humans after they led the farming lifestyle. La Brana 1 shows that at least some of their predictions were correct.
The man's skeleton, along with that of a male companion, was discovered in 2006 in a
cave in what is now northeastern Spain. The site, known as La Brana-Arintero, sits about 5,
000 feet above sea level, and the cave provided a cold, refrigerator-like environment that
preserved his DNA.
In the lab, scientists were able to take out enough DNA from a single tooth to reconstruct La Brana I's entire genome (基因组). They compared it to the DNA of other ancient Europeans and
determined that he was a closer match with hunter-gatherers than with farmers.
When it came to genes that would influence La Brana I's appearance, the researchers found that their 7,000-year-old subject had versions of two skin pigment(色素) genes that are either very rare or nonexistent among Europeans today. Then they looked at other places in the genome that influence pigmentation and found a mix of ancient and modern gene variants(变体). Taken together, La Brana 1's DNA “is likely to have resulted in dark skin pigmentation and dark or brown hair," they wrote.
However, his DNA indicates that his eyes were most likely blue, the scientists found. This suggests that gene variants for light-colored eyes and skin did not spread together, they wrote, adding that La Brana 1's combination “of dark skin and non-brown eyes is unique and no longer present in contemporary European populations. " Today,
