A huge lake of salty water appears to be buried deep in Mars, scientists reported this week. The presence of water raises the chances of finding life on the red planet. The discovery is based on observations by a European spacecraft. It has excited experts. Water is necessary for life, and scientists have long hoped to prove that it is present on Mars.

Cassie Stuurman is a geophysicist at the University of Texas. In 2016, she found evidence of a huge ice deposit(沉积)on Mars. “If these researchers are right, this is the first time we've found evidence of a large water body on Mars. ”Stuurman said. Researchers are not yet sure how deep the area of water is. So, they cannot say whether it is an underground pool, or just an area of soft and wet soil.

In order to find the water, Italian researchers examined radar signals. The signals were collected over three years by the European Space Agency's Mars Express spacecraft. The results suggest that a 20-kilometer-wide water body lies below ice that is 1.5 kilometers thick. They believe the area is close to the planet's southern pole.

    Mars is very cold, but salt in the water may have kept it from freezing. It is the same as when you put salt on a road to prevent ice from forming. The water would be extremely cold, right at the point where it's about to freeze. And it would be salty. Such conditions are not ideal for life to form. But, she said there are bacteria on the earth that have been able to survive in similar conditions.

Mars has been a popular planet for exploration, with some groups placing instruments on its surface and others examining it from space. In May, NASA launched another spacecraft, the InSight Mars lander which will dig deep into the data under the surface after it reaches a flat area of the planet in November.

(1)、Where do the Italian researchers believe the water body on Mars is?
A、In a pool. B、Above ice. C、In soft and wet soil. D、Near the southern pole of Mars.
(2)、What can we learn about the water on Mars from the text?
A、It is probably filled with creatures. B、It flows on the surface of Mars. C、It is mainly in the form of solid. D、It is probably at the freezing point.
(3)、What will the InSight Mars lander do when it reaches Mars?
A、Dig a hole to protect the lander itself. B、Explore the surface of Mars. C、Gather information under the surface of Mars. D、Examine Mars from space.
(4)、What is the main idea of the text?
A、Life used to exist on Mars. B、Researchers find new species on Mars. C、Mars will be the humans' second home. D、Water is buried beneath Mars' surface.

    April 4th was just another day on a Western Australia farm for Zac Mitchell, until it suddenly wasn't. In an unexpected accident, the cattle worker was feeding the animals in his charge when one bull cleaned him up and kicked his hand up against the rail, resulting in the thumb on his right hand being cut off. “My thumb was still hanging on the rail... when I got up off the ground,” Zac Mitchell says.

    His co-workers tried their best to preserve the thumb for reattachment, placing it on ice in a cooler, but two surgeries to put Mitchell's thumb back in place failed. That's when doctors came up with another suggestion: Remove one of his big toes to where his thumb used to be.

    Mitchell's lead surgeon, Sean Nicklin, understood the man's dilemma at first, calling it a “bit of a crazy idea”. After all, Zac Mitchell did not want to be injured in another part of his body. But as the thumb is incredibly important function-wise, Mitchell eventually gave in. Nicklin explains that the big toe is surprisingly fit for a thumb switch: Nerves sync up (同步) nicely, and it looks more like a thumb, though a giant one, than any other alternative they may have come up with. He added that big toes aren't as necessary for balance and walking as people believe. As far as the foot goes, occasional “fine balance” activities like surfing might be difficult, but most people without a big toe function fine in everyday tasks like walking and even competitive sports.

    The eight-hour surgery went well, and Mitchell is expected to have a year or so of recovery in front of him before he heads back into the fields.

    In a big room on the second floor of the New York City Department of Sanitation's East 99th Street garage, 63-year-old Manhattan native Nelson Molina was listening to a Frank Sinatra CD he found in the trash. "The Way You Look Tonight" was playing through a music player. In fact, the entire space was filled with items strangers threw away. "My family kept everything," said Molina. "Nowadays, people throw it all away." Molina, during his 34 years as a sanitation worker (环卫工人), gave these items a second life.

    Molina grew up in a housing project with his parents and five other kids in the family and had a habit of picking up unused items at a young age. "My family was poor, so we didn't get much for Christmas," he said. "I'd go out to look for a toy for my sisters, maybe a truck for my brothers." He kept his early morning habit secret from his friends, but not out of embarrassment: "I didn't want the competition."

    On the job, Molina had his sixth sense for finding items. "I could tell, sometimes just by the sound, whether a bag was filled with bottles or a different kind of glass," he said. He kept special finds on the truck, and then put them in out-of-the-way places in the sanitation garage. After almost 10 years, he began showing his discoveries. "It's not a normal practice." said NYC Department of Sanitation assistant chief Keith Mellis. Recently, a team of New York University students has taken on the task of cataloging (分类) the tens of thousands of objects, in hopes that the collection, which has hardly been open to the public, might one day be shown in an official sanitation museum.

    Scientists have connected the "fat gene" with the "happy gene". They believed there could be genetic evidence which explains why fat people are often happier than their skinny friends. The breakthrough could be an explanation for why fat characters, such as The Laughing Policeman and Father Christmas are often described as joyful and kind.

    FTO is the major genetic contributor to being fat. But it is also connected with an eight percent reduction in the risk of depression. Researchers at McMaster University in Canada had been studying whether there was a connection between being fat and being depressed. They found the opposite was true.

    They studied 17, 200 DNA from participants in 21 countries. Results showed people with FTO gene—the fat gene—showed less signs of depression. This finding was supported by three additional international studies.

    Professor David Meyre said, "We set out from the belief that being depressed and being fat both deal with brain activity. We thought that fat genes may be related to depression. However, we have discovered a molecule (分子) contributing to depression. It is the first evidence that an FTO fat gene is connected with protection against depression.

    In a recent interview, actress Lisa Riley said she was more than comfortable with her size. She said she is a "big, really happy" girl who is lucky enough to be confident in her own skin, and added, "Many people want to be thinner. Not me. I love being different and it drives me mad that people don't believe I'm happy with what I am."
