PLAYA GRANDE, COSTA RICA----This resort town was long known for Leatherback Sea Turtle（棱皮龟）National Park, nightly turtle beach tours and even a sea turtle museum. However, on a beach where dozens of turtles used to nest on a given night, scientists spied only 32 leatherbacks all of last year.
With leatherbacks threatened with extinction, Playa Grande’s turtle museum was abandoned （抛弃）three years ago and now sits among a sea of weeds. And the beachside ticket office for turtle tours was washed away by a high tide in September. “We do not promote that as a turtle tourism destination any more because we realize there are far too few turtles to please,” said Alvaro Fonseca, a park ranger.（管理员）
Even before scientists found temperatures going up over the past decade, sea turtles were threatened by beach development, drift net fishing and Costa Ricans’ interest in eating turtle eggs. But climate change may cause the most serious harm to an animal that has lived in the Pacific for 150 million years.
Sea turtles are sensitive to numerous effects of warming. They feed on reefs, which are dying in hotter seas. They lay eggs on beaches that are being covered by rising seas and more violent waves.
More uniquely（独特地）, their gender is determined not by genes but by the egg’s temperature during development. Small rises in beach temperatures can result in all-female populations, obviously problematic for survival. If the sand around the eggs hits 30 degrees Celsius, the gender balance shifts to female; at about 32 degrees they are all female. Above 34, you get boiled eggs.
On some nesting beaches, scientists are artificially cooling nests with shade or irrigation and trying to protect broader areas of coastal property from development to ensure that turtles have a place to nest as the seas rise.
【小题1】Why does the resort town stop promoting its turtle tourism?

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.
【小题1】According to the passage, plastic_______.

How hard we have all prayed(祈祷) to grow up quickly, and looked forward to the happy days of being a grown-up and enjoying the many interests that a youth should have. ?
At last, you have grown up. At least you are no longer a child. They call you “young lady”. You then enjoy the pleasure of being a young lady. You are proud of being a grown-up teenager. People welcome you-this young lady-heartily. You are glad that your prayer has been answered. ?
But there is always something that troubles you a lot. You say; “Papa and Mama, give me some money please. My pocket money is all gone already. ”?
“No”, they say, “your age is a dangerous age. If you have too much money to spend, it won’t do you any good. ” Then you have to stay at home because you dare not go out with an empty pocket.
Another time you tell your grandma, “Grandma, see, I am a grown-up now. ”?
“Good, now, you can sit here and knit (编织) this for me while I go and have a rest. ” To show that you are no more a child, you have to sit there the whole afternoon doing the work, which only a grown-up can do. After an hour, you find it hard to do, and give the knitting basket back to your grandma. Your grandma criticizes your work. You hear what she says, “Such a big girl can’t do such easy work. ” You wish then you were a child again. ?
But the fact is, you are growing up, and you can’t help it. That’s the way it goes!

Due to the increasing number of violent acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can assure their safety and well-being. Teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons charged with the safety of the students.
The main reason for violent acts are the films and cartoons that fill the children’s time. They want to do everything. They watch on TV and never think of the results, and they may hurt a classmate or a teacher.
On the other hand, parents are not fully satisfied with the children’s results obtained in classes and they consider private classes would have better results.
When a teacher has to watch 30 students in class he can’t probably see what each of them is doing, how he is writing, or if he understands the explanations. At home the teacher can explain in detail everything the child doesn’t understand as many times as he considers proper.
And many times, the child grows fond of the teacher at home, who becomes his best friend, and who helps him whenever he needs someone to talk to. 
However, the best solution would be a mixture between the education received at school and that at home, because school makes children communicate and socialize. Keeping a child at home for fear that something bad might happen to him only makes the child’s character weak and prevents him from knowing what real life is. Staying in a glass bowl only does harm to the child.
All in all, schools have been created to help children, not to harm them, so it’s best to keep children in these special places, where they learn, laugh, have fun and make new friends.
