We just waved goodbye to this year's Mother's Day.1., but there are still things you might not know about Mother's Day.
The founder fought back.
Although Julia Ward Howe first suggested a day for mothers, Anna Jarvis campaigned for a national day for moms, in memory of her own mother, Ann Jarvis, who had spent years working to provide resources for poor mothers in West Virginia.2., but within a few years, Jarvis became annoyed with how commercial the day had become and started a petition（请愿）to cancel the holiday.（That clearly didn't come to pass.）
It is an active day on the phone lines.
3.. One study suggests that the more widespread use of cell phones has greatly increased the amount of contact adult children have with their mothers. So don't be lazy: your mom definitely expects to receive your call, and not just with a text message.
4.
If you're thinking about taking your mom out to eat, you might want to consider which time of the day will have enough open tables. Mother's Day is the busiest day of the year for restaurants, with some 80 million adults dining out, which tops even Valentine's Day. Therefore, if you'd like to treat your mom to her favorite cuisine, go earlier on that day.
All in all, Mother's Day is set up to honor mothers' love and care for the family, so even a handmade card can show your appreciation.5.
A.Mother's Day became an official holiday in 1914
B.Their devotion deserves your attention and respect
C.Some of you may find that day not new to you at all
D.Some of you might have forgotten to send greetings
E.Many people honor more than one mother in their life
F.It is the busiest day of the year in the restaurant industry
G.Call volume in the US goes up 11 percent on Mother's Day
A few weeks ago, scientists at Ukraine's Vernadsky Research Base in Antarctica found their usually white surrounds were covered in a shocking blood-red. For such a mess, the culprits behind this horrible scene are tiny.
“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.
1.What does the underlined word “culprits” in Paragraph 1 mean?
A.Risks. B.Chances.
C.Effects. D.Criminals.
2.What can we know about Chlamydomonasnivalis?
A.They can be found anywhere. B.They are sensitive to temperature.
C.They grow slower than before. D.They survive only one melt season.
3.What can be inferred from the last two paragraphs?
A.Ice and snow will soon disappear in the Antarctic.
B.Microbial communities bring about extreme weathers.
C.The Southern Hemisphere is warmer than the other parts.
D.Climate change and algae growth interact with each other.
4.Which can be a suitable title for the text?
A.Why Snow Turned Blood-red. B.How Algae Began in the Arctic.
C.Why Climate Changes Greatly. D.How the Snow Reflects Sunlight.
Nowadays, to work remotely, all you need are a computer and an Internet connection. According to a new study, employees who can work from anywhere else are generally happier than those who work onsite(现场的)in an office.
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.

Last summer, I had to stay in the room during the period of my recovery from cancer after the operation. It was unexpected that life highlighted everything that I might tend to take for granted in the normal course.
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(雷达)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.

2.How did the author enjoy the pouring-coffee experience?

C.By chatting with the strangers. D.By pouring coffee slowly.
3.What happened when the author changed her lifestyle?
A.She had more time for reflecting on her past.
B.She found joy in ordinary daily activities.
C.She became impatient with any shop owner.
D.She liked listening to mysteries in busy cities.
4.What is the main purpose of this article?
A.To tell people how to make coffee tasty.
