A 2 billion year old Martian (火星的rock appeals to have at our time been full of water from the surface of the Red Planet.

“Here we have a piece of Mars that I can hold in my hands. That’s really exciting,” Carl Agee, director of the Institute of Meteoritics at the University of New Mexico, told the Associated Press.

Agee led a team of scientists who published their report on the newly discovered meteorite (陨石),nicknamed Black Beauly, The rock is estimated to have contained 6,000 parts per million water? and scientists believe it likely interacted with water at a time when most of the planet’s surface was believed to have been arid.

The baseball-size rock was discovered in the Sahara, and scientists say it contains more evidence of water than any of the other known Martian rock samples.

“It’s fairly fresh. It hasn’t been subjected to a whole lot of weathering (风化作用),” University of Alberta meteorite expert Chris Herd told the AP.

Billions of years ago an eruption on the surface of Mars, likely caused by a volcano or planet collision, sent the rock into space, where it eventually made the journey to Earth, Agee and his team said the sample is “strikingly similar to the volcanic rocks examined by the NASA rovers Spirit and Opportunity on the Martian surface.”

Over the years, scientists have collected more than 60 Martian rock samples, with most being discovered in the Sahara and Antarctica. The new sample is much older than most of the other specimens, which are about 600 million years old or younger. The oldest known sample is an estimated 4.5 billion years old.

Nisha Pradhan is worried. The recent college graduate just turns 21 and plans to live on her own. But she’s afraid she won’t be able to stay safe. That’s because she isn’t able to smell.

Back home, her family do her smelling for her. She’s moved in with them for now, but she’s looking for a place of her own. “Now that I’m searching for ways or place to live as an independent person, I find that the sense of smell is important to how we live our lives,” Pradhan says.

She says when she was a child she liked to eat and ate a lot. But there came a point where she lost interest in food.

“One of the first things that people notice whenever they have a smell problem is that food doesn’t taste right any-more,” says Beverly Cowart, a researcher. That’s because eating and smell go hand in hand. How food tastes often relies on what we smell. “When you lose your sense of smell, your whole sense of food flavor s changed and reduced,” Cowart says, “You can still taste the basic tastes. What you’re missing are the small distinctions.”

“When I go out to eat I have often found that that food is very tasteless to me. I never feel full,” she says. “I think a lot of us today like to pretend to be food lovers and we all like to talk about ‘Oh, I think this could use a little bit more flavor,’ or ‘I think this has a hint of meat,’ I can’t really participate in those conversations,” she says.

Pradam thinks her smell loss also may have affected her memory. Pradhan may be on to something, according to biologist Paul Moore. “When smell signals come in, you feel about them first. And then you think about it and then the memory is laid down. So without the feel part, the thinking about its part doesn’t come. And that means no new smell memory gets created.”

1.What problem does Pradhan meet with at present?

A. That she has no sense of smell.

B. That she doesn’t have her own house.

C. That she lacks life skills to live alone.

D. That she is too nervous to live alone.

2.What can we infer from what Beverly Cowart said?

A. People with a smell problem have no food tastes.

B. Lack of smell sense makes eating a dull experience.

C. Different food tastes the same for people of smell loss.

D. People feel hungry easily for lack of smell sense.

3.When eating out, Pradhan_______.

A. has a sense of being full quickly B. often has a good appetite

C. pretends to have good smell sense D. feels left out sometimes

4.What does the underlined sentence mean?

A. Pradhan may be crazy. B. Pradhan may be foolish.

C. Pradhan may be right. D. Pradhan may be forgettable.
