Study lamps are vital to learning. Finding the best lighting for study is important for everyone. For the sake of maximizing the use of time and energy, and for the very important goal of preserving eyesight, anyone reading for understanding needs not only adequate light, but light that ensures reading with ease. Only when eye strain(疲劳) is not interfering does the learning process move forward.

Desk lamps

You can purchase a large number of stylish desk lamps from lamp stores and online. The products range from precious ones to casual ones, from traditional ones to ultra-modern(超现代的)ones. They feature such desirable additions as dimmer switches and night lights. Some have battery backup in case of power failure and a choice of OttLite bulbs that duplicate natural sunlight.

LED desk lamps

MetaEfficient reviews the most recommended LED desk lamps. These lamps come in many different styles and brand names and are valued for their directed beam of light, lack of heat and exceptional energy efficiency and brilliance. LED study lamps are made in goose neck and swivel(转圈)styles, as well as the more modern Z-bar and the human-like- figure of the Moppel light.

Safest desk lamps

According to Knol, StudyLite is the safest of all desk lamp designs. Not only does it provide LED light, freeing people from UV and IR radiation, but it has been tested to be eye-friendly. It has all the advantages-low cost and long life-of any LED lamps, but it is also equipped with rechargeable battery. Its design and choice of colors make it desirable for more than its efficiency.

German cities are redrawing road markings to create new cycle paths for the duration of the Covid-19 lockdown, as cyclists demand more space to physically distance on their way to work.

Local authorities in the Kreuzberg district of Berlin trialled (试行) temporary widening of two cycle paths on 27 March, arguing it would help cyclists keep the required 1.5-metre distance apart while car traffic was down owing to Germans' coronavirus (冠状病毒) restrictions.

On Friday, the council declared the plan a success because it had improved cycling safety while not blocking traffic.

The council said it had used removable tape and mobile signs to mark out the widened paths, which can be removed when the current restrictions on movement are lifted.

Residents in 133 other German cities have formally submitted applications for similar pop-up bike paths to their local authorities on the back of a campaign by Environmental Action Germany (DUH), an environmental NGO.

The campaign group cites new research linking air pollution to higher coronavirus death rates as an argument for redrawing road signs across the country. "The coronavirus is showing us that clean air is necessary," said DUH's chair, Jurgen Resch. "It is now especially important to temporarily make it more important for people to move safely on their bikes. This will help improve air quality, enable exercise in fresh air while keeping a safe distance and avoid unnecessary accidents."

In Germany, bike repair shops are allowed to work because of the Covid-19 going on. Three federal states, Berlin, Saxony-Anhalt and Mecklenburg-Vorpommern, have allowed bike shops to stay open.

A planet the size of Jupiter has been discovered and it is one of the hottest ones known to us. This has made scientists think about how planets are formed.

Planets such as Earth have more oxygen than carbon, but what if the composition（组成）is just the opposite? This is a question opened up by a recent discovery of a diamond planet by US and UK scientists. The planet is 1200 light years away from Earth and was observed using NASA's Spitzer Space Telescope. Dr Marek Kukula explained that researchers initially used the Super WASP(Wide Angle Search for Planets) robotic observatories operating continuously, all year around. They detected the planet, then it was observed with the Spitzer Space Telescope, which detected the heat coming from the planet, and from that heat signature they can tell what this planet is made from.

The planet is very different to Earth. "It's giant planet," explains Dr Kukula, "a gas planet, a bit like Jupiter in our solar system. But the interesting thing that they've discovered is that it has a very different composition to the planets in our solar system. This planet has more carbon than oxygen." This suggests that there is more than one way to make a solar system and the range of planets in the universe could be much wider than previously thought.

Dr Kukula says that if there are smaller planets in the same solar system with a similar composition, rich in carbon, their rocks could be rich in minerals such as carbon and diamonds, unlike Earth which has silica (硅石), the sand that rocks on Earth are made from. "This is where this diamond planet idea comes from; they haven't actually detected a diamond planet yet," explains Dr Kukula.it' s hypothetical (假设的), "but you can imagine strange landscapes with black graphite rocks lying around and the surface could be covered with sticky liquids instead of water".

Foldable phones are once again facing questions about their durability(耐久性).The Galaxy Z Flip and the Motorola Razr are now both available to buy in the US-but early reports suggest the screens are easily damaged.

One media published photos of two layers of the Razr's display separating, affecting the touch screen. The Galaxy flip, meanwhile, boasts(自夸)a "flexible glass" display—but tests appear to show it scratching(刮擦)as easily as plastic.

In a statement, Samsung said the display had a protective layer, and had undergone extensive testing. "While the display does bend, it should be handled with care, "it said.

The Z Flip's "pretty thin glass" is one of Samsung's primary marketing messages for the new phone. But a durability test conducted by popular Zack Nelson, a regular buyer, suggested it was no more durable than soft plastic screen, and could even be dented(痕)by fingernail.

Nelson said Samsung's screen scratched exactly how plastic screen would react. "I don't know what material this is, but Samsung definitely shouldn't be calling it glass," he said. He found that the screen of the Motorola Razr scratched as easily but it is not marketed as "glass".

The Motorola Razr was put on sale 13 days ago in the US, but Raymond Wong, an editor says the flexible screen on his handset has already broken. The upper layer of the Razr's screen separated from the bottom, creating "a giant horizontal air bubble" for no apparent reason. He wrote that the fault appeared after 45-minute train ride during which the phone was in his pocket. The screen was completely warped from hinge-to-hinge with the top layer raised like a poorly applied screen protector. But Mr. Wong said that apart from the visual problem, the damage has affected the responsiveness of the touchscreen.

The outbreak has forced people to work from home and given many couples the chance to see each other at work. But, after all, living together and working together are not the same.

⒈ Put the problem on the table

Knowing what your partner does is one thing but seeing them in action is another. "We are forced into the intimacy (亲密), not just with spouses (配偶), but also with kids or whoever else is in the home," said Karen Bridbord, a psychologist in New York City. Talk about any insecurities you may have whether it's participating in a video meeting or being eavesdropped on and what you need in terms of a work environment. Then create a schedule and set boundaries when it comes to separating work life and personal life.

⒉

You might be learning that your spouse is fan of all the office cliches or holds too many meetings—but it's best to keep that to yourself. Even if you think your intentions are good, don't offer any unsolicited（主动提供的）feedback when it comes to your partner's' work style. And don't mistake complaining as an opportunity to criticize. "Even if a partner is complaining about work, you shouldn't see that as an invitation or opportunity to provide critical feedback," said Anthony Chambers, a chief academic officer. ""

⒊ Don't complain a lot

These working conditions aren't ideal for many people right now—especially if you are juggling kids and other care giving responsibilities . However, try not to keep score of who is doing what around the house, or whose work is more pressing.

A. Provide an inside look.

B. Allow them to complain and you just listen.

C. Avoid treating each other like colleagues.

D. This can leave you feeling overburdened and exhausted.

E. The first step in making this situation work is to talk about it.

F. How to do with this "new colleague" to maintain a harmonious relationship?

G. In this way, you're more likely to arouse sympathy from the partner which will help negotiate boundaries.

Last week I went shopping in the supermarket. I got to the front of the 1 and put my groceries through the checkout. I was about to pay, when I 2 that I didn't have my bankcard with me. I 3.Then I remembered I left it at home when I 4 something online. All I had was $30 in notes and some coins in my wallet. I was short 5 at least $25, and I needed to buy most of the items.

I started to 6 to the checkout lady. "I'm sorry, I stop the queue. Can I put these things back, and then think I'll 7 these. Oh, no, need that."

An Irish lady was 8 behind me, next in the queue. "Excuse me, Dear," she said. "Oh, I'm so sorry," I replied, "I'm 9 you up." "Of course not. I know 10 you feel. This happens to all of us at some point. Now please use my 11 to pay the bill and you can be on your way."

I was astonished by her kindness, 12 even. No matter how I insisted otherwise, she was 13 to help me. Afterwards I asked for her telephone number to 14 and pay her back. "No," she said, "rather pay it forward. You may do a good deed for the next person in need."

By helping others, can we start chain 15 of positive feeling and charity that can benefit our whole society?

Trees, plants and flowers are all around us and we enjoy their beauty every day. However, we are so used to them  we may even take them for granted without (realize) how much inspiration they have given us. In fact, nature has inspired many of the most (fascinate) designs around us, including those in architecture. Nature  (present) in various architectural designs.

Today, architects continue to explore ways  (capture) the beauty of natural forms, to mimic the way nature works or even to make natural organisms part of a building. ArtScience Museum, Singapore was designed to show the  (connect) between nature and the modern city environment in which it sits. Visitors are often amazed to find themselves in an urban building that so (true) captures the beauty of natural forms. Harare's Eastgate Centre is  superb example of biomimicry (仿生学). To use biomimicry is to create structures (base) on natural forms and processes. Creating buildings such as these enables us to live  closer harmony with our environment.
