“Our scientists have identified them under a microscope as Chlamydomonasnivalis(雪地衣藻),” said the National Antarctic Scientific Centre of Ukraine in a Facebook post.

These green algae, a type of seaweed, are common in all icy and snowy regions of Earth, from the Arctic to high mountain regions. They lie still during the freezing winter, but once the sunlight warms enough to soften their world, the algae awake, making use of the melt water and sunlight to rapidly bloom.

“The algae need liquid water in order to bloom,” University of Leeds microbiologist Steffi Lutz told Gizmodo in 2016. “The algal blooms contribute to climate change,” the center stated.

A study in 2016 showed that snow algal blooms can decrease the amount of light reflected from the snow by up to 13 percent across one melt season in the Arctic. “This will surely result in higher melt rates,” the researchers wrote.

In 2017 environmental scientists calculated that microbial communities contributed to over a sixth of the snowmelt where they were present in Alaskan ice fields. Their experiments showed that areas with more melt water led to the growth of 50 percent more algae and places with more algae melted further.

This Antarctic summer has certainly seen a lot more melt water than usual. Temperature records keep changing, leading to rapid melting previously only seen in the Northern Hemisphere.

Video conferencing company Owl Labs surveyed 1,202 full-time US workers from the ages of 22 to 65, and discovered that 62 percent of the respondents worked remotely at least some of the time and 38 percent worked onsite. Of the remote workers, 49 percent worked remotely full-time.

As it turns out, working remotely—or the idea of it—makes people happy, 83 percent of the survey respondents agree that the ability to work remotely would make them happier, and 71 percent of workers who do get to work remotely said their job makes them happy, compared with 55 percent of office-only workers.

In the study, full-time remote workers said they're happy in their job, 22 percent more than people who never work remotely. The reasons why respondents said they decided to work remotely were better work-life balance(91 percent), increased productivity/better focus(79 percent), less stress(78 percent), and to avoid a commute(通勤)(78 percent).

One reason why remote workers might be happier is that they were more than twice as likely to earn more than $100,000 per year. And the higher they were on the corporate(公司的)ladder, the more likely survey respondents were to have the privilege of working remotely: The job levels with the greatest percentages of remote workers were founder/CEO-level(55 percent)and vice president(46 percent).

Loyalty is another factor: Remote workers are 13 percent more likely than non-remote workers to stay with their current job for the next five years—making remote work a win-win for employees and employers alike.

Not only are remote employees happier, but they are prepared to work longer hours, according to the report. Remote workers said they work over 40 hours per week, 43 percent more than on-site workers do.

【1】What can he learned about the respondents in the survey by Owl Labs?

A.49 percent work remotely full-time.

B.55 percent are not satisfied with their work.

C.83 percent prefer to work in an office.

D.About 40 percent are office-only workers.

【2】Compared with remote workers, onsite workers are .

A.less loyalB.more productive

C.less creativeD.more hardworking

【3】It is more likely for those with higher job levels to .

A.live freelyB.have double income

C.work remotelyD.work less time

【4】What is the text mainly about?

A.The choice of working sites.B.The benefits of working remotely.

C.The tendency of future jobs.D.The qualities of offsite employees.

On the first morning, my children presented me a coffee pot. I liked to begin the day with a cup of coffee and was eager to try the pot.

When I made coffee, it spilled out over the whole table. Fortunately, nobody was there to see my embarrassed look! I kept trying, but each morning would see me wiping up the coffee. Then I realized that if I poured very slowly there would be no spilling.

This was at first a very painful experience. My normal practice was to rush through breakfast so that I could get on with my day. But at that moment I learned not only to pour slowly but to enjoy the experience: the smell, the taste, and the stillness of a new day.

It helped me to reflect upon whether there were other areas of my life 1 was rushing through. Most of life, it seemed. Strangely, those we consider loved ones may go of radar(雷達)when we would expect them to enquire about our well-being. However, others we seldom keep in touch with came into our lives suddenly, full of concern, well-meaning advice and love.

After the recovery period, I started to leave extra time to do even the most ordinary tasks. When shop owners would apologize for keeping me waiting, I would say, "Not a problem, I'm not in a hurry." Even hanging out washing became pleasurable when a couple of extra minutes of standing still, and listening to the birds singing in the trees around me became part of my routine.

Besides, one of my favorite experiences living in the inner city for many years was sitting on the front doorstep of our home spending time with strangers. We sat on the steps, each of us with a cup of coffee in our hands, listening to each other's stories. It was one of the warmest things about living in a busy city.

I'll have a long holiday before the final examination, but I have a fantastic plan. I'm so eagerly to get together with all my friends that I will visit them first. Then I planned to have a party with my family, which makes me really exciting. After that, I'll probably visit the place of interest both at home and abroad, and it will give me a chance experience different cultures. Last but not least, learn some skills is on my schedule as well. I'll ask my mom to teach me to cook just in case I have to feed me one day. I hope everything will turn out as being expected.
