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.

Guide to Stockholm University Library

    Our library offers different types of studying places and provides a good studying environment.

Zones

    The library is divided into different zones. The upper floor is a quiet zone with over a thousand places for silent reading, and places where you can sit and work with your own computer. The reading places consist mostly of tables and chairs. The ground floor is the zone where you can talk. Here you can find sofas and armchairs for group work.

Computers

    You can use your own computer to connect to the wi-fi specially prepared for notebook computers; your can also use library computers, which contain the most commonly used applications, such as Microsoft Office. They are situated in the area known as the Experimental Field on the ground floor.

Group-study places

    If you want to discuss freely without disturbing others, you can book a study room or sit at a table on the ground floor. Some study rooms are for 2-3 people and others can hold up to 6-8 people. All rooms are marked on the library maps.

    There are 40 group-study rooms that must be booked via the website. To book, you need an active University account and a valid University card. You can use a room three hours per day, nine hours at most per week.

    When we're in need, we always turn to our parents for help. But would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions (延伸) of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends?

    In the past the generation gap included a technology gap, where children were up to date with latest technology and parents were left behind, content to continue their day to day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation to educate themselves about social networking sites.

    These days many people are attracted to social networking sites because they can choose who they have around them; there's also a certain amount of control over privacy that we don't get in real life. Sometimes we feel that privacy is violated (侵犯)when we must accept a “friend” request from a parent or family member.

    It's a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don't want to “reject” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.

    A recent survey suggested that parents shouldn't take it personally if their child ignores their request: “When a teen ignores a parent's friend request, it doesn't necessarily mean that they are hiding something, but it could mean that this is one part of their life where they want to be independent.”

    Perhaps talking with parents and giving explanations would help soften the blow if you do choose not to add them to your friends list.

    Ladies and Gentlemen, thank you. Well, ni­hao. (Laughter) It is such a pleasure and an honor to be here with all of you at this great university, so thank you so much for having me. I'm here today because I know that our future depends on connections like these among young people like you across the world.

    That's why when my husband and I travel abroad, we don't just visit palaces and parliaments(国会) and meet with heads of countries. We also come to schools like this one to meet with students like you, because we believe that relationships between countries aren't just about relationships between governments or leaders—they're about relationships between people, particularly young people. So we view study abroad programs not just as an educational chance for students, but also as an active part of America's foreign policy.

    Through the wonders of modern technology, our world is more connected than ever before. Ideas can cross oceans with the click of a mouse. Companies can do business and compete with companies across the world. And we can text, email, Skype with people in the world.

    So studying abroad isn't just a fun way to spend a time of learning; it is quickly becoming the key to success in our times. Because getting ahead in today's workplaces isn't just about getting good grades or test scores in school, which are important. It's also about having real experience with the world beyond your borders­experience with languages, cultures and societies very different from your own. Or, as the Chinese saying goes: “It is better to travel ten thousand miles than to read ten thousand books.”

    Ever walked to the shops only to find, once there, you've completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we've accepted that a forgetful brain is as much a part of aging as wrinkles and gray hair. But now a new book suggests that we've got it all wrong.

    According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s — much later than previously thought.

    Furthermore, rather than losing many brain cells as we age, we keep them, and even produce new ones well into middle age. For years it's been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.

    This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive (认知的) tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving. Where they performed less well was number ability and perceptual speed — how fast you can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.

    Neuroscientists are also finding that we are happier with aging. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we're younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we've learned our lessons and are aware that we have less time left in life: therefore, it becomes more important for us to be happy.
