    Do you ever wonder why trees begin to bud (发芽) earlier in some cities? Scientists finally found the answer but it's not very pleasant. New science suggests a relationship between light pollution and the timing when trees produce buds, which signals the arrival of the spring season.

    Light pollution is defined by the Lighting Research Center as the unwanted consequence of outdoor lighting such as street lights. Excessive (过多的) man-made light at night results in disturbed natural cycles, and also prevents the observation of stars and planets at night. But its effect on the environment goes beyond that.

    By studying some trees, researchers found out that trees that are more exposed to artificial lighting at night bud up to 7.5 days earlier than those at the natural nighttime setting. And they found out that light had a more significant effect than temperature when the buds came out. The early budding may cause problems for insects, which feed on leaves, and the birds which then feed on them in turn. Professor Richard French Constant, who helped lead the research, explained that more than the budding of trees, the study implies the danger to the balance of the ecosystem. “At the moment, caterpillars (毛毛虫) are timed to hatch to make the most of the opportunities to feed on freshly budded leaves, and birds hatch in time to feed on the young caterpillar,” he said.

    Migratory (迁徙的) birds are also negatively affected by light pollution. The glare might confuse them and make them lose their flying sense. The phenomenon might explain why some birds accidentally knock into buildings.

    Such results stress the need to pursue studies that aim to measure the effect of light pollution. If the issue were left to continue, it is estimated that by 2100, spring would begin almost a full month earlier than it does today.

    Most people will tell you that without a cup of coffee in the morning, they cannot function. Coffee is a good drink when consumed in right amount. {#blank#}1{#/blank#}

    Legend says that Kaldi, an Ethiopian, discovered his goats enjoy eating coffee plants. Curious, he tasted the leaves and began to dance around. A passing monk (僧侣) witnessed the scene and took some back to his fellow monks. Later that night, the monks experienced extreme inspiration. {#blank#}2{#/blank#} Soon Arabia was roasting coffee beans. By 1000 A.D. Muslims were drinking coffee to stay awake. A merchant from Venice introduced coffee to Europe in 1615. By 1696, the Dutch started growing the coffee bush in Java. By 1723, coffee plants were introduced to the Americas. Today, coffee is the most popular drink in the world.

    Caffeine (咖啡因) is the major chemical in coffee. Caffeine poisoning can occur if more than 400 milligrams of caffeine is drunk in a short period, which is about four to five cups of coffee. {#blank#}3{#/blank#} So it should be avoided before bed.

    {#blank#}4{#/blank#} Studies have shown that it helps cognitive (感知) skills in elderly women. Women who drank three cups of coffee daily scored higher on memory tests than women who drank one cup of coffee.

    Large amounts of coffee can cause nervousness, worries and heartburn. However, if mixed with milk, it is fine. {#blank#}5{#/blank#} The more you drink, the more you depend on it. For some people, just one cup of coffee a day is OK.

A. Coffee has many benefits.

B. Coffee can be addictive like any drug.

C. Caffeine will also cause sleep difficulty.

D. The caffeine in coffee can actually help fight disease.

E. However, it is considered harmful if taken in large amount.

F. Drinking coffee while you have this kind of disease will make it worse.

G. Whether the legend is true or not, the discovery of coffee dates back to 800 A.D.

    A conference was held with former technology industry leaders calling for urgent measures to protect children from smartphone addiction (上瘾).

    Among those urging major changes is Tristan Harris—a former high-level employee at Google. He just launched a group that will seek to gather and publish evidence of how digital devices and social media can harm children and young people. Harris says he believes companies like Google, Facebook and Apple have a "moral responsibility" not to create technology products that can "hijack how the mind works".

    The conference where Harris spoke was sponsored by Common Sense Media, a child and family activist group. The organization says research suggests that half of all teenagers feel addicted to their mobile devices, while about 60 percent of parents believe their kids are addicted.

    The group also cites a recent study of eighth graders that found heavy users of technology were 56 percent more likely to say they are unhappy, while 27 percent more likely to be depressed. Even Facebook cited research last year suggesting that social media use can harm mental health when used in certain ways.

    James Steyer is the founder of Common Sense. He says more than half of schools in the US are already members of the organization. The group provides teachers and parents with learning materials intended to help students develop critical thinking skills and balance their digital lives.

    Some US schools, however, have tried to limit or remove technology to improve learning. One of them is in Silicon Valley, the center of the American tech-industry.

    The Waldorf School of the Peninsula does not use any computers or digital technology in its education programs up to the seventh grade. The schools' website says while Waldorf teachers recognize the role technology can play in the classroom, it must wait until the student reaches the right developmental age. Normally when students reach high school, they are allowed to use computers and digital tools in the classroom.

    According to a recent survey on money and relationships, 36% of people are keeping a bank account from their partner. While this financial unfaithfulness may appear as distrust in a relationship, in truth it may just be a form of financial protection.

    With almost half of all marriages ending in divorce, men and women are realizing they need to be financially savvy, regardless of whether they are in a relationship.

    The financial hardship on individuals after a divorce can be extremely difficult, even more so when children are involved. The lack of permanency in relationships, jobs and family life may be the cause of a growing trend to keep a secret bank account hidden from a partner, in other words, an "escape fund".

    Margaret's story is far from unique. She is a representative of a growing number of women in long-term relationships who are becoming protective of their own earnings. Every month on pay day, she banks hundreds of dollars into a savings account she keeps from her husband. She has been doing this throughout their six-year marriage and has built a nest egg worth an incredible $100,000. Margaret says if her husband found about her secret savings he'd be hurt and would take this as a sign that she wasn't sure of the marriage. "He'd think it was my escape fund so that financially I could afford to get out of the relationship if it went wrong. I know you should approach marriage as being forever and I hope ours is, but you can never be sure."

    Like many of her fellow secret savers, Margaret was hurt in a former relationship and has since been very guarded about her own money.

    Coming clean to your partner about being a secret saver may not be all that bad. Take Colleen for example, who had been saving secretly for a few years before she confessed (坦白) to her partner. "I decided to open a savings account and start building a nest egg of my own. I wanted to prove to myself that I could put money in the bank and leave it there for a rainy day."

For some people, walking or running outdoors is a great way to work out. What may not be so pleasant is seeing trash all over the ground. Well, some people are doing something about it. They are plogging!

"Plogging" began in Sweden. The name combines the Swedish word "plocka", which means "to pick up", and the word "jogging", which means "to run slowly". A Swedish man named Erik, started the movement in 2016. On the World Environment Day website, Erik says that he moved to Stockholm from a small community in northern Sweden. Each day he would ride his bike to work. Concerned about the amount of trash and litter he saw each day on his way to work, he took matters into his own hands. 

Plogging, by that term, may have officially begun in Sweden. But many people who exercise outdoors have been doing this for years. Take Jeff Horowitz for example. He is a personal trainer in Washington, D.C. He often picks up trash while running outside. He even has turned it into a game; he will try to pick up the trash without stopping. "I didn't know it was a thing really. This is just my personal ethics____(道德标准), where I go for a run and if I happen to see a piece of garbage lying around and it's within reach—it is a kind of a little test for me to see if I can grab it and throw it in a near trash can without stopping. And that way, I think, it gives me a little exercise and a little focus for my run. And it helps clean up the neighbourhood," he announced. 

Today, plogging is an official activity, one that is becoming increasingly popular. Cities around the world now hold plogging events. "I would just hope people would think twice before dropping garbage on the ground. We have containers on every block. So, it's easy to put your garbage in the trash cans. I just think people should think about it a little bit more. I do hope one day there will not be a need for plogging," said an interviewee.
