It was Thursday, September 12,1940.Four French teens were out exploring in the woods off the northern slopes of the Pyrenees.Many years before, an old pine tree fell and left a large hole in the ground.The teenagers were curious and they started to explore the area and fell into one of the most important archeological(考古的) finds of the twentieth century!
There are over a hundred limestone(灰岩) caves in this region of France.Some were inhabited by humans thousands and thousands of years ago.Between 15,000 and 17,000 years ago, humans painted lively creatures such as cows, bulls, horses, and even cats on the walls of the caves.
Why did they mark these walls? Was it to tell a story? Was it to record a famous battle? There are many mysteries and ancient secrets still waiting to be discovered in the cave of Lascaux.There were dots in many of the paintings.What do these dots mean? Were they meant to record time, a calendar? Deep in the cave, there is a drawing of a “birdman”．What does this mean? Was it a place for sacred ceremonies? No one knows for sure.
The actual cave of Lascaux was closed in 1963 due to the overabundance of tourists visiting the site.The carbon dioxide that people were breathing out was causing damage to the fragile(易损的) cave paintings.Up till now the Lascaux cave is still closed for tourists.Only a specialist can visit the cave by a special order that must be made out almost a year in advance.Not more than six persons can enter the cave per day.Two days a week, the cave is completely closed.Due to the great interest of numerous tourists, in 1983 Lascaux Ⅱwas opened for tourism.It is an exact replica of the cave of Lascaux.

举一反三
On April 22,2012, we decided to go green every single day for an entire year. This meant doing 365 different green things, and It also meant challenging ourselves to go green beyond the easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.
With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.
Over the course of Our Green Year, we completely changed our lifestyles. We now shop at organic(有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.
Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.

This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.
Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.
The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person’s actions. They realized that each of them can make a difference.
小题1:These teenagers went on the journey around the world .
| A．to experience the most serous environmental problems on the earth |
| B．to bring the kindness of America to the other parts of the world |
| C．to go on sightseeing around the world |
| D．to call on more teenagers to join Earthwatch Institute |
A. They had to pay for their journey on their own expense.
B, They often had to move from one hotel to another.
C. They had to take great pains to collect environmental information.
D. They received a warm welcome every time they arrived at a new place.
小题3:It can be inferred that Earthwatch Institute could be .
A. an international university that takes in students from all over the world
B. a TV station that makes programmes on the beautiful scenery of the earth
C. a travel agency that organizes adventure trips specially for school children
is a legal requirement that all kids be educated, though. When parents believe they can give their kids a better education--- or have other reasons for not wanting to send their kids to a local school --- they may choose home schooling.
However, if a kid hates school, home schooling is probably not the escape he is looking for. Home schooled students can learn just as much as they would in regular school if they and their parents work hard to cover all the subjects and experiences necessary. Parents who home school usually have higher levels of education than parents who do not. They already have the skills to educate themselves about teaching their kids.
Parents who home school have to be able to put the time and skill into not just teaching, but also researching lesson plans and resources(资源). So they have to know how to find the information necessary to teach their kids. State schools often provide home-schooling parents with a curriculum(课程), books and materials and places to meet. Some state schools will point parents to other resources for brushing up on forgotten subjects. Or parents may receive continuing education at local colleges or universities.
小题1:According to American law, _______________.
| A．all kids shall go to school |
| B．all kids must receive education |
| C．home schooling parents shall receive continuing education |
| D．state schools must give support to home-schooling parents |
| A．are short of money | B．dislike schools |
| C．used to work as teachers | D．are well-educated |
| A．They should have enough time. |
| B．They should have some skills in teaching. |
| C．They must receive special curriculums at the university. |
| D．They have to be able to know lesson plans and resources. |
| A．reviewing | B．changing |
| C．choosing | D．discussing |
| A．Home schooled kids learn fewer. |
| B．Home schooled kids spend less time studying. |
| C．Being a home-schooling parent needs a lot of effort. |
| D．Home schooling will replaced school education. |
If blood is red, why are veins（静脉）blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-up?
Baby (or “milk”) teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they’re gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine(脊柱)becomes shorter and more curved due to disuse and the effects of gravity（重力）. Many (but not all) men and women do lose height as they get older. Men lose an average of 3—4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy(眩晕的)?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But, when you suddenly stop spinning the system goes out control, and your brain thinks you’re moving while you’re not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area—from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animals on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease.
小题1:What is the colour of blood in a vein near the surface of the skin?
| A．Blue | B．Dark reddish purple |
| C．Red | D．Light yellow |
| A．Because their spine become more bent. |
| B．Because they are more easily affected by gravity. |
| C．Because they keep growing backwards. |
| D．Because their spine is in active use. |
| A．The brains of the other mammals are as complex as those of humans. |
| B．When our brain senses the spinning, we will feel dizzy. |
| C．In the long run, our brain probably works harder than our heart. |
| D．Our feelings and emotions come from the most developed area in our brain. |
| A．it takes four to five times as much blood to feed our brain as to feed our heart. |
| B．when adult teeth are gone, they cannot grow back. |
| C．the reason why spinning make us dizzy. |
| D．how we can grow taller. |
| A．To give advice on how to stay healthy. |
| B．To report the latest discoveries in medical science. |
| C．To challenge new findings in medical research. |

Fear still fills the hearts of men, women and children of Washington. In May of 1980 during the eruption of Mount Saint Helens, the Batsquatch showed itself in the shadows of clouds from the eruption. In 1994, a local mountaineer was able to take pictures of the Batspuatch making the rumor(谣言) seem real. During this event some farm animals seemed to disappear though luckily no humans were reported missing at the time. The local mountaineer told about his meeting with the Batsquatch. When he suddenly heard a loud deep voice from the shadows, the mountaineer was knocked down. He tried to look for the creature(生物) that had made the sound. He saw a great creature with purple wings in the sky. It looked like it was about 30 feet tall.
The mountaineer kept this story a secret in fear of being laughed at by others but when new stories came in about the Batsquatch he shared his story.
The reality of the Batsquatch can no longer be ignored. It is only a creature that is trying to live. Respect! This is how we should take news such as this. Respect for a living creature instead of fear.
