In a surprising discovery about where higher life can survive, scientists have found a shrimp -like creature and a jellyfish swimming beneath an Antarctic ice sheet.
About 180 meters below the ice where no light can get through, scientists had figured nothing much more than a few microbes (微生物) could exist.
That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp-like creature came swimming by and then parked itself on the camera’s cable. Scientists also pulled up a tentacle (触须) they believe came from a jellyfish.
“We were operating on the presumption that nothing’s there.” said NASA ice scientist Robert Bindschadler. “It was a shrimp you’d enjoy having on your plate.”
“We were just gaga (狂热的) over it,” he said when talking about the 7.5cm long, orange creature starring in their two-minute video. Technically, it’s not a shrimp. It’s a Lyssianasid amphipod, which is distantly related to the shrimp.
The video is likely to inspire experts to rethink what they know about life in harsh environments. And it has scientists thinking that if shrimp-like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?
Cynan Ellis – Evans, a scientist of the British Antarctic Survey called the finding fascinating. He said it was possible the creatures swam in from far away and don’t live there permanently.
But Kim, who is a co-author of the study, doubts it. “The site in West Antarctica is at least 19 km from open seas. Bindschadler drilled a 20 cm-wide hole and was looking at a tiny amount of water. That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small area,” she said.
“Yet scientists were puzzled at what the food source would be for these creatures. While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t,” Kim said.
“So how do they survive? That’s the key question.” Kim said.
“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.

Not too long ago, our teacher, being a “tree-hugger” (as the kids call her), had us write an essay on an environmental issue . I was eager to start, but something made me stop.

“What is an environmental issue ?” one kid asked . “What if we don’t care about the environment ?” another complained. “ It’s not like it affects me .”

These comments astounded me .I have always cared about the environment and assumed that others did too. From the surprised look on my teacher’s face, I could tell she felt the same way.

In no time, I finished my essay . In my essay I wrote about logging(伐木), which is an important industry, but if we continue to cut down trees without replacing them, it will damage the environment.www.zxxk.com

There are so many things that we can do to save our world. Recycling, of course, is always a good thing, but not everyone has a recycling plant nearby ( I don’t ) . There are other ways to help the environment . Plant a tree. Don’t waste water.

I can’t stand it when a person’s excuse for not caring is “Nothing’s going to happen in my lifetime, so why should I care ?” Sure, the chances of something terrible happening are slim, but I want people to realize that if we don’t deal with it, someone will have to eventually. Do you want that to be your children ?

When my teacher told me to read my essay to my class, I was a little embarrassment because I didn’t want everyone to call me “tree- hugger”. I realize now that if being a tree-hugger means you cares about the environment, I’m a tree-hugger 100 percent. I just wish more people were too.

1.Why do the students call her teacher “tree-hugger” ?

A. She likes hugging trees.

B. She knows a lot about trees.

C. She grew up in the country.

D. She cares a lot about the environment.

2.The underlined word in Paragraph 3 can be replaced by ____.

A. helped B. changed C. shocked D. interested

3.Paragraph 5 is mainly about ____.

A. what we can recycle

B. how we can save the earth

C. why we should protect the earth

D. what damage we are doing to the earth

4.We can infer from the text that _____

A. the students don’t like the teacher

B. the teacher liked the author’s essay

C. the author is ashamed of being a tree-hugger

D. the author should have written a better essay

Britain's most popular lie has been disclosed, with one in four people admitting using "sorry I had no signal" when returning a missed mobile phone call, a survey found．

Researchers found the average Briton tells on average four lies every day or almost 1500 every year． Almost one in six men admitted they were most likely to lie to their wife or girlfriend, on average at least twice a day．The most popular lie was saying you had no mobile phone signal．with one in four people admitting regularly using the little white He．It usually came after they hit the "ignore" button when their mobile rang．

Three quarters of people think women are better Hare．The research found 46 per cent of girls have been caught lying, compared to 58 of men．
