When you sleep, do you ever realize that you are dreaming? If yes, then you have had a lucid dream (清醒梦). 1. Only some people are able to have them. Now, scientists have found ways to help more people to have lucid dreams, Live Science reported.
Denholm Aspy from the University of Adelaide in Australia found that certain skills are key to helping people have lucid dreams.
First, people can train themselves to figure out whether they are dreaming or not. For example, someone may look at a clock, look away, and then look back. 2. Then, they might dream about this trick while sleeping. But in their dreams, the time on the clock may change very quickly. So people know they are dreaming.
Another trick is to wake up after five hours of sleep. 3. During this time, repeat the words, “The next time I’m dreaming, I’ll remember that I’m dreaming.” Then, go to bed again to enter rapid eye movement (REM，快速眼球运动) sleep. In REM sleep, people are more likely to be aware of their dreams.
Scientists found that those who used these tricks had a 17 percent success rate at having lucid dreams. 4.
In a lucid dream, people might study a hobby and then become better at it in real life, according to Aspy. For example, you might learn to play the piano in a lucid dream. 5.
A.Then, stay awake for a while.
B.The time should stay the same.
C.This was far higher than if they did nothing.
D.People learn new skills faster in a lucid dream.
E.It is hard for most people to have a lucid dream.
F.Then, your real-life piano skills might improve.
G.Some people will need more time to fall asleep and have a dream.
By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friends’ new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?
Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choice. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.
Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.
Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.
Also, what you carelessly post on the Net can come back to trouble you. Revealing(泄露) personal information on social sites can make users vulnerable(易受伤害的)to crimes like identity theft, stalking, etc. Many companies perform a background check on the Web before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.
Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.

Benefits of green spaces
We all know the value of taking a walk in the fresh spring weather. It allows your mind to relax and forget about the problems in everyday life. Studies have commonly shown the benefits of being around green spaces, including gardens, urban parks and forests.
But did you know that being in contact with these natural surroundings during childhood could positively impact your mental health as an adult?
A study by the Barcelona Institute for Global Health (ISGlobal) surveyed 3,600 people from all over Europe, including Spain, the Netherlands, Lithuania and the UK.
The all-adult study gave participants a questionnaire on how frequently they used natural spaces during childhood — for example, playing in a garden, riding a bike at the park or hiking in a forest. They were also asked about the importance they put on using such places.
Volunteers were then given a psychological test, which included a variety of questionnaires and problem-solving activities, to analyze their nervousness and feelings of depression (抑郁) within a four-week period.
The results consistently showed that the people who were more exposed to natural spaces had higher mental health scores compared to those with lower childhood exposure — as did those who attached higher importance to using green spaces.
The study’s coordinator (协调员), Wilma Zijlema, wrote that the results “show the importance of childhood exposure to natural spaces for the development of a nature-appreciating attitude and a healthy psychological state in adulthood”. She also stressed the importance of “recognizing the implications (含义) of growing up in environments with limited opportunities for exposure to nature”.
According to the study, 73 percent of Europe’s population only has limited access to natural spaces. Mark Nieuwenhuijsen, director of ISGlobal’s Urban Planning, said that “Many children in Europe lead an indoor lifestyle … so we call on policymakers to improve the availability (可得性) of natural spaces for children.”
While this study was based in Europe, a lack of green space can affect anyone, anywhere. So remember to make time to immerse yourself in nature, as your mental health is just as important as the physical one.

When Rachel Ratelle saw a news video of a burned koala trying to climb a tree to safety in fire-ravaged (火灾肆虐的) Australia, she decided to do something about it.
She looked up wildlife rescue and relief agencies in Australia to find out what they needed most. Besides donations, many organizations asked for hand-sewn (手缝的) and knitted pouches (袋子) and wraps for koalas and other animals that were burned or had lost their homes and parents in the fires.
This idea attracted Ratelle, but there was just one problem.
“I’d never sewn in my life,” said Ratelle, 17, a senior at Rancho Buena Vista High School in Vista, US. “Giving money seemed like something too simple. But I wanted to directly help these animals by doing something myself, so I decided to learn how to sew.”
Over the next few months, Ratelle bought her own sewing machine and taught herself how to sew via videos online. Then she purchased 18 yards of fabric and sewed 25 pouches of different sizes and shipped them off to For Australian Wildlife Needing Aid (FAWNA), one of several relief organizations that have rushed to rescue koalas, kangaroos and other species suffering from burns.
A week later, she received a photo from FAWNA with a young joey (幼兽) in one of her larger pouches. “It made me feel like I contributed to the world and it showed how a simple act of kindness can go a long way,” said Ratelle, who hopes to study biology for a future career as a nurse practitioner.
“I plan to use my new sewing skills to help animals and people devastated (蹂躏) by natural disasters,” she said.
According to the World Wildlife Fund, it estimated that 1.2 billion animals have died, as a result of the bushfires, which have burned more than 26 million acres in Australia.
Several craft guild (手工业行会) websites around the world have mobilized (动员) for Australian relief by making the animal pouches. Karen Newberry and her two daughters Madison, 12 and Rochelle, 8, from San Diego also offered their help in such a way. For Newberry, “it was a big push that made we crafters, sewers to realize there’s something more we can do than just make things for ourselves,” she said.

A.What inspired Ratelle to learn to sew.
B.What is needed to save koalas and other species.
C.The poor living conditions of wild animals in Australia.
D.Different ways to help koalas and other animals in Australia.
2.How did Ratelle feel when she received a photo from FAWNA according to the text?
A.Proud. B.Calm.
C.Surprised. D.Disappointed.
3.The statistics (统计数字) in Paragraph 8 are used to show ______.
A.how frequent the bushfires are in Australia
B.how harmful the bushfires are in Australia
C.the great varieties of wild animals in Australia
D.the difficulties facing relief organizations in Australia
4.What do Newberry’s words in the last paragraph suggest?
A.People should stay united through difficult times.
B.Life is not easy for crafters and sewers in Australia.
C.It is challenging for crafters and sewers to do relief work.
D.Crafters and sewers can do more to help animals.
