1 . A study on astronauts found that a short sleep during the day up to two and a half hours long improved working memory performance. Working memory includes focusing attention on one task while holding other tasks in memory, so a poor working memory could result in errors.
Taking a short sleep may make you think more clearly for the period right after you wake up and maybe hours into the day. Taking a short sleep once or twice a week could lower the risk of heart attacks, according to a 2019 study published in the journal Heart. After tracking more than 3,400 people between the ages of 35 and 75 for slightly more than five years, the researchers found that those who enjoyed occasional short sleep — once or twice a week, for five minutes to an hour — were 48% less likely than those who didn't take a short sleep to experience a heart attack or heart failure.
A lack of quality sleep could lead to overeating because not enough sleep is believed to stimulate hunger and stop hormone (荷尔蒙) signals that communicate fullness. The findings were important because women were at high risk of fatness and sleep disorders, the researchers said, which could both be driven by a high intake of food. Taking a short sleep has been found to improve your creativity. The right side of your brain might experience a strong mental feeling during a short sleep, research suggested. The right side is the hemisphere (半球体) most associated with creative tasks, such as imagination and thinking, while the left is more logical. Researchers monitoring the brain activity of 15 people found that the right side of their brain communicated busily with itself as well as with its left part. The left side of the brain, however, remained relatively quiet. In a January 2020 study of 2,214 Chinese adults aged 60 and older, those who took afternoon sleep for five minutes to two hours showed better mental response than those who didn’t take a short sleep.

2 . The aftermath (后果) of an earthquake can be horrible, but it is important that you are attentive and focused after an earthquake happens. Fires, gas leaks, and injuries are all dangers you might face after an earthquake.
Check yourself for injuries.
Aftershocks are smaller earthquakes which follow the main shock of an earthquake.
Exit the building and go to a safer place once the shaking has stopped. The structure of the building you’re in may have been weakened by the main earthquake.

G.Therefore, you should leave as soon as possible in case of any aftershocks. |
3 . Have you ever gone to a museum or a show and been completely blown away by a piece? If you haven’t, go out and get cultured. I’m a student at the College of Visual and Performing Arts where we create all kinds of art every day.
First of all, we need to be inspired. You may think that’s easy. In fact, anything can serve as a concept of a work of art.
The process can take weeks, months, and even years to be fully realized. Once completed, we need to share it and find an audience and provide an environment to display our work.
Creating art is an art in itself. It is really not as easy as many people think.
A.Outsiders think our jobs easy. |
B.We should be quiet and creative. |
C.We might choose other fields as well. |
D.Resources are also a huge factor in making art. |

F.And the negative thoughts love to overpower our minds. |
G.It takes time, patience and space when things don’t go as expected. |
4 . The Science and Technology Facilities Council (STFC) and University of Central Lanca-shire (UCLan) share findings of a project to improve student engagement with science, technology, engineering and mathematics (STEM).
It’s long been acknowledged that students from disadvantaged backgrounds are under-represented in science, technology, engineering and mathematics careers. Now, research conducted by UCLan and funded by STFC shows the causes of this problem and points to innovative solutions. The Blackpool Physics; Inspire, Engage, Research (PIER) project found that primary school children from low socio-economic areas are just as interested in science but lack knowledge about possible science careers.
The PIER project is following a group of pupils as they progress from Grade 6 to Grade 9, using surveys, interviews and other assessments to measure interest in science. These initial findings suggest that attempts to increase science participation among young people should not simply promote the subject as “fun” or “interesting”. Instead, greater impact could be achieved by demonstrating clearly how science can open possible future career opportunities.
Many of the pupils taking part in the study understood that studying science could be useful but few could explain why, suggesting a need for greater education about STEM careers. As well as broadening our understanding of the issue, the PIER project is solving the problem head on. The team has carried out a variety of activities each year for the participants, including “meet the scientists” events, trips to UCLan’s Alston Observatory as well as family science events at school.
Lead Researcher and STFC Fellow in Public Engagement, Professor Robert Walsh, said, “Much government policy towards boosting science in higher education focuses on an assumed lack of interest and desire in low-socioeconomic groups.” However, the enthusiasm is already there and this “hidden science identity” needs to be revealed and translated into real-life prospects for these young people. We’re recommending that programs instead allow young people to explore their science identity more fully and provide innovative ways to discover the jobs that studying science may lead to.

5 . Margot doesn’t have a garbage can. It doesn’t need one because Margot simply doesn’t cause anything to get thrown away. The restaurant doesn’t allow any type of single use plastic. Margot, which opened last year, is one of the small but growing restaurants around the world aiming to avoid not only food leftovers, but also any garbage.
“Food waste has been increasing as an issue for restaurants over the last 10 years,” says Calvin Brown. He runs the Sustainable Restaurant Association. Based in the United Kingdom, the organization helps food business become more environmentally responsible. He says that food waste contributes to releasing the greenhouse gas, so there is strong motivation to reduce waste and help the environment.
In the USA, food waste and packing account for nearly half of the material sent to landfills. Restaurants from McDonald’s to Starbucks are addressing this issue with “no straw Mondays” and limits on single-serving plastic, but a handful of restaurateurs are trying to get rid of rubbish entirely. There’s also economic case to be made for waste reduction. One study shows that restaurants save seven dollars for every dollar invested in anti- waste methods.
Avoiding food waste is the first and perhaps most obvious challenge for sustainable restaurants. Doug McMaster, chef at Silo in London, only serves a set menu. This removes the worry that one particular item won’t sell well, and will spoil in the refrigerator. Compost (堆肥) is a necessity as well. Nolla (meaning “zero” in Finnish) in Helsinki, Finland is giving compost to its suppliers as well as its diners. Nolla also has food- tracking software more commonly used among corporate food service companies to keep track of what sells and what rots.
Sometimes restaurants call themselves environmentally friendly, but they might just be using the label. Calvin offers some pointers on what to look for to make sure a restaurant is truly committed to sustainability.

Last night after I had the supper, I went to do my homework. I finished all the work except the last one in half an hour, but I still couldn’t work itself out. An hour late, I wanted to giving up. But my father told me to keep on work. I made it the help of my father at last. I smiled, but so does my father. From the experience I know nothing in the world is impossible whether I make up my minds to do it.
