All over the world the need for more laptops and computers increases each year. Networks have been part of our life. Probably everyone with a portable device(移动设备)has once logged on to a public WiFi network without paying for it while they are having a coffee, on a train, in a shopping mall or at a hotel. However, is this kind of public WiFi network safe?
Some networks are better protected than others because encryption(加密) methods are used. Therefore, they are safer than others. But a survey in 2015 showed that more than 950 million records were not protected, including addresses, emails, birth dates, phone numbers, passwords and so on. These open WiFi networks are really not safe, because it is very easy for hackers(黑客)to break into the operating system and get people's private information.
Most smartphones and laptops, by themselves, search and connect to WiFi networks. They usually prefer a network with a connection that has been used before. Hackers' devices are able to record these searches and look like the trusted WiFi networks. When these smartphones and laptops log on to the networks which are not real, hackers can easily steal their private information.
So next time, when we want to use our laptops or our smartphones in public places which offer free WiFi networks, please think twice or take safe measures before using them.

【推荐3】The Eastern Daily Press (EDP), a newspaper covering Nolfolk, northern parts of Suffolk and eastern Cambridge shire, is published daily in Norwich, UK. Founded in 1879 as a broadsheet called the Eastern Counties Daily Press, it changed its name to the Eastern Daily press in 1872. The paper is now owned and published by Archant, formerly known as Eastern Counties Newspapers Group.
Soon, a Google-backed project named Local Recall giving access to over 150 years of Eastern Daily Press newspaper at the click of a button or spoken question will be released. Archant is home to archive that holds tens of thousands of newspapers-with some Norwich Mercury editions dating from as far back as the middle of the 18th century. In 2017, Archant applied to the Google Digital News Innovation Fund to breathe new life into the archive. The company received £600,000 from Google and part-matched the fund to start Local Recall.
The project began in early 2018 and with help from Norwich-based artificial intelligence and chatbot company Ubisend along with specialist historical scanning companies Towns Web Archiving and Findmypast, Local Recall has since digitized an estimated 750,000 pages of EDP newspapers. In the process, more than seven million articles have been uploaded online. The digitization process, while impressive, could not always guarantee exact recreation of the text. Factors such as paper thickness, marks on the page and general wear and tear could make results confusing. It became clear there was a need for human eyes to pick out errors.
Meanwhile, a platform was provided for an army of more than 800 volunteers to help proofread and correct the stories from days gone by. Melanie Duncan, 47, from Helleson, got involved in the project after learning about it through Facebook. “It’s a window of memories into our past that we might have no knowledge of otherwise. The project is an invaluable source of accessible information. I have enjoyed every minute of doing it so far,” she said. Soon, users will be able to explore EDP archives from October 1870 right up to the latest news through a subscription service available on monthly and annual price plan.

【推荐1】There’s no doubt that one of the greatest human achievements is the exploration of the space. Ever since astronaut Yuri Gagarin became the first person to be sent into the orbit around the moon in 1961, scientists have been pushing the boundaries further and further. But until now the exploration into the unknown has been dominated (主导) by men.
Of course, in the past, women were also included in the space projects and played an active role on the ground and behind the scenes. For example, they worked as seamstresses (女裁缝师), sewing vital spaceflight components. In fact, many of NASA’s key works would never have been possible without them. Recently Hollywood produced a movie called Hidden Figures to focus on a group of American female mathematicians, especially the black women, who helped NASA send the first American into space. But this was not women’s only contribution. Back in 1963, Soviet astronaut Valentina Tereshkova became the first woman to be sent into space. However, after that, space flight programs were slow to employ women. In the USA. NASA didn’t accept applications from women to become astronauts until 1978.
But attitudes have changed and leading officials at NASA say that the first person to set foot on Mars should be a woman. The space agency aims to have a sex-balanced workforce but can only achieve that if equal numbers of men and women are trained for science and technology jobs. As Allison McIntryre told the BBC, “My director is a woman. We have female astronauts. We haven’t put a woman on the moon yet. And I think that perhaps the first person to step on Mars should be a woman.”

【推荐2】Many parents worry that showing negative emotions in front of their children will cause them to suffer. For example, children may end up thinking it’s their fault or simply “catch” the emotion. Indeed, this worry has a sound basis — the phenomenon of “emotional contagion” (情绪感染) is real, and one recent study found that parents can transfer their fear of going to the dentist, for example, to their children.
On the other hand, there is the natural idea that we should “be real” with our children, and that they will benefit from watching a parent who struggles and eventually deals with their negative emotions like any other human being.
There are three concepts to consider when it comes to emotional display in front of children: suppression (压抑),“uncontained” expression, and talking about emotions. Suppression of emotion is when you hide the outward signs of an emotion. Unfortunately, it doesn’t work very well — the act of suppressing your emotion actually increases your blood pressure. Observers can pick up on your distress despite your efforts to hide it, making them feel stressed. The recent research has also found that when parents feel negative emotions and keep them from their children, they experience lower relationship quality and decreased responsiveness to their child’s needs.
On the other hand, “uncontained” expression of anger and sadness by the parent is also not salutary for the child. Uncontained means high intensity emotion, with no attempts to regulate or take ownership of it. Shouting, smashing (摔) things and blaming someone else for “making you angry” are all example of this .
So, what is the middle ground? That would be talking about emotion taking ownership of them and showing your child that you are trying to deal with them. Classic research found that six-year-old kids had better emotional understanding and perspective-taking skills if their mothers had talked to them about their emotions at the age of three. In fact, the more the mothers had talked, the better the outcome would be.
So next time you feel sad, angry or frustrated and your child is watching you expressing emotion, do explain what’s going on in terms they can understand.

【推荐3】The Hadza hunter-gatherers of Tanzania live a life that has not changed much over ten thousand years. They have no crops, no house animals, no permanent shelters. In spite of long exposure to agriculturalist groups around them, the Hadza have maintained their lifestyle.
The story of the spread of agriculture is the story of growing population density (密度). Villages formed, then cities, then nations. Agriculture’s rise, however, came with a price. It introduced infectious diseases, social inequality, occasional famines (饥荒) and war. Professor Jared Diamond of UCLA (University of California, Los Angeles) has called the adoption of agriculture “the worst mistake in human history”— a mistake from which we have never recovered.
Looking at the Hadza, you can see why he came to this conclusion. They do not engage in warfare. They do not live densely (稠密地) enough to be threatened by an infectious outbreak. They have no known history of famine (饥荒). The Hadza diet is more stable (稳定 的) and varied than that of most of the world’s citizens. They live almost entirely free of possessions. They enjoy an extraordinary amount of leisure time, “working” — actively pursuing food — only four to six hours a day.
The chief reason the Hadza have been able to maintain their lifestyle so long is that their homeland is not an inviting place. Recently, however, population growth has brought a flood of people into Hadza lands. The region has generally been viewed by outsiders as unused, a Place in need of development. The Hadza, who by nature are not a combative (好战的) people, have almost always moved away instead of fighting.
There are many things to envy about the Hadza, mostly what free spirits they appear to be. Free from schedules, jobs, bosses, bills, traffic, taxes, laws, social duties and money. But who of us could live like them? It’s incredibly risky. Medical help is far away. One bad fall from a tree, one bite from a snake, and you’re dead. The fact is that it’s too late for us to go back to the Hadza lifestyle. Of greater concern is that soon it may be impossible for them to maintain theirs.

【推荐1】Fast walkers may live longer than dawdlers (缓慢的人)— regardless of their weight, a new study suggests.
Researchers at Leicester University analyzed data on 474, 919 people with an average age of 52 in the UK Biobank between 2006 and 2016. They found women who walked briskly had a life expectancy of 86.7 to 87.8 years old, and men who kept up the pace had a life expectancy of 85.2 to 86.8. Slow walkers hadn’t much encouraging prospects (前景): women had a life expectancy of 72.4, and men of 64.8 years old, if they were more leisurely in their movements. According to the paper, published last week, that ratio held true even if the fast walkers were severely overweight. It does not necessarily mean fast walkers will live longer. Experts say it suggests walking speed could be a simple way for doctors to judge their patients’ general health alongside other tests.
It is hardly the first study holding up walking speed as a powerful evidence that appears to improve and determine our health.
In 2011, the Journal of the American Medical Association (JAMA) published a study by Stephanie Studenski, who found the same: walking speed was a reliable predictor of life expectancy.
In 2013, US researchers found walking pace was linked to lower heart disease risk and longer life expectancy. In 2018, a study from the University of Sydney found picking up your walking pace to even an “average speed” could cut your risk of premature death by a fifth.
And Tom Yates, the physical activity professor at Leicester who's behind the latest study, has been publishing findings on this connection for years.
In 2017, he analyzed the same UK Biobank data and found walking speed appeared to affect the risk of dying from heart disease — concluding that the slowest walkers were twice as likely to suffer a heart-related death compared to quick walkers.
1. What does the underlined word “briskly” in paragraph 2 probably mean?A.Casually. | B.Quickly. | C.Actively. | D.Energetically. |

【推荐2】What would you like to be when you grow up? A teacher? A doctor? An astronaut? What do you need to do to achieve your dream job?
Perhaps you think that studying well and then going on to work hard will get you the successful career you want. We are continuously taught that our hard work will eventually pay off.
But a government survey has shown that hard work is not the only thing that will help you to move up the ladder(梯子). Two thirds of people believe that who you know matters more than what you know when it comes to social activity. So are the connections that you have more important than your education?
Seventy-six percent of the people in the survey believed that family background is important in influencing your chances of success. They believed that if you are privileged(有特权的) from birth, you are more likely to have a successful career, especially if your family is wealthy.
Even if you don't have a privileged background, the people you know can still make a difference to your career. Networking is a skill which is encouraged by many career advisers. Some companies run networking workshops to try and encourage staff to meet other people, to communicate and build relationships. It's a valuable skill.
But the survey also showed something quite interesting. Although most people believed that networks are more important than education, many people put their own career success down to talent, rather than background. 41% of the people said that their parents' income had influenced their life, but at the same time, another 41% believed that they had achieved their own success.
So which is more important, what you know or who you know? It seems that by working hard and making lots of connections, the answer may be that both are very important.
1. Which of the following is closest in meaning to the underlined part?A.Practice makes perfect. | B.Nothing is impossible. |

【推荐3】Dogs wag (摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli (刺激物) with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners — a positive experience — their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.
