2 . We know it can be hard to put your phone to bed before you sleep. However, if you’re trying to improve your sleep, you really should ditch your phone at least an hour before bedtime. Luckily, our experts can help.

Scientific evidence suggests that the blue light emitted from your phone, tablet, computer, and TV suppresses (抑制) your body’s production of melatonin, a hormone (荷尔蒙) that plays an important role in your sleep cycle. Melatonin release in the evening helps you relax before bedtime. A 2013 study that analyzed technology use and sleep patterns with data from a National Sleep Foundation poll found that using devices like phones was tied to more sleep disruption than electronics that aren’t interactive.

Many of us use the excuse that our mobile devices serve as our wake-up calls, or keep them nearby to use meditation apps. If you want to use your phone as an alarm, consider setting it a couple of hours before you turn in for the night, and then setting the phone itself to bedtime mode for the rest of the evening.

Here’s another groundbreaking idea: You could get a real alarm clock. After reviewing them at Reviewed, we recommend the Sharp Dream Caster. Not only is it easy to set a wake-up time, the clock includes white noises and rain noises to help you sleep, plus a number of volume settings to pick what works best for you.

But an alarm clock won’t help you avoid doom-scrolling through social media. Take things a step further by avoiding using electronic devices. You can try reading a book (one made of paper), taking a bath or drinking a cup of chamomile tea.

Finally, if you want to keep up your meditation practice screen-free, consider the Morphée. It looks like a little music box and comes with a variety of breathing exercises and soundscapes to help you get to sleep.

The World Health Organization (WHO) has announced a shocking finding about the air we breathe. It has found that almost everyone on Earth breathes unhealthy air. The WHO made     1    (it) air quality update ahead of World Health Day on April 7. The update reported that 99 per cent of the world’s population breathes air     2     goes beyond WHO air quality limits. It looked at data from over 6,000 cities in 117 countries. People     3    (live) in lower- and middle-income countries breathe the poorest-quality air. Millions of people die in these countries because of pollution-related diseases. The WHO said: “After surviving a pandemic, it is unacceptable to still have 7 million preventable deaths due     4     air pollution.”

The WHO said its report highlighted the need to move away from fossil fuels. It asked governments to do more     5     (reduce) levels of air pollution. It said: “Current energy concerns highlight the importance of speeding up the transition to cleaner and     6    (healthy) energy systems.” It added that high gas prices, energy     7    (secure), the dangers of air pollution, and climate change mean the world must be less dependent on fossil fuels. The WHO report     8    (include) many recommendations for change. One of these is     9     use of clean energy for cooking, heating and lighting. Another is to “build safe and affordable public transport systems and pedestrian- and cycle-friendly     10    (network)”.

4 . “Shuan Q” is a meme(网络流行语)which can be used as a popular way to say “I’m speechless” with a matching emoji(表情包)at ached behind. No-one can deny the power of the Internet. Some believe it makes language weaker but some see a brighter side, believing it makes online communication easier between strangers.

An elementary school teacher in Hangzhou, Zhejiang province, says that the evolution of Internet slang is not all fun and carefree. From his daily observations, he believes the “geographic boundary” between Internet slang and formal language is disappearing. On many occasions, the composition she has received from pupil have been flooded with abbreviated slangs(网络梗).

During last year’s Two Sessions, several representatives put forward proposals such as “regulating online language” and “banning vulgar(粗俗)words”, specifically to address this issue, expressing the need to reduce online language misuse and strengthen the protection of Chinese.

However, many experts and scholars of linguistics and communication including Feng Zhiwei disagree. Feng, believes that Internet language is a natural product of the dynamic development of language, and it is not necessary to ban it.

When we visit museums, we see cultural artifacts -from everyday household items to precious carvings and statues, that give us glimpses into the     1     cultures and communities from around the world. However,     2     surrounds these artifacts and whether or not countries should return these pieces of culture if they were stolen or forcefully taken during colonization.

By the 18th and 19th centuries, European countries such as Britain, France and the Netherlands had     3     many African and Asian countries. During their rule, they either seized artifacts or took them as spoils of wars, and brought them to their own countries where they are now displayed in museums.

In 2017, the Government of Benin in West Africa     4     with the British Museum in London to return their renowned Benin Bronzes, a     5     of thousands of metal sculptures and plaques, which were previously hung in the royal palace of the Kingdom of Benin.

The debate regarding this issue took a turn in 2018 when under President Emmanuel Macron a report was released that directed that all heritage objects brought to French museums (without the permission of their original countries) be     6    . With the official release of this report. museums all across Europe began reconsidering their previous policies on colonial treasures.

Those who propose returning these objects to their original homes argue that with technology enabling virtual museum tours, returning these artifacts to their homeland does not take away the opportunity to learn about them. Furthermore, the country of origin will receive a     7     part of their heritage back, and these artifacts will be given a chance to be truly appreciated under proper historical context. Those against the restoration claim that culture is a     8     treasure and the artifacts are in fact “cultural ambassadors” that promote     9     and understanding They believe that while stealing them was wrong, history is full of “good” and “bad” actors. Moreover, they feel that keeping the cultural objects in the current museums have kept millions of artifacts     10     from disfiguration and damage.

Living in a     1     (high) competitive society, the idea that the purpose of life is to work is popular or even dominant. Most bread earners believe that     2     (finance) guarantee is more realistic and important for a person and for his family. So they take it for granted     3     devoting to work is the most reasonable and worthy thing to do.

Nevertheless,     4     (object) think that work is only a means to have a better life. They argue that there are more important things than work in life, such as friends, personal interests, social     5     (responsible) and so on. They think that life will be dull and     6     (meaning) with work as its aim.

In my opinion, we should strike a balance     7     work and life. On the one hand, to be a diligent worker is necessary and meaningful. On the other hand, we should not be workaholic, or we will lose many such significant things in life     8     love and friendship. Wherever life takes us and whatever choices     9     (lay) out before us, something worth     10     (remember) is that our work, when done well, will not only help us make a living but also help make a life for ourselves and for others.

9 . If having to make a choice between reading an e-book and a printed book, which would most people choose? Some would go for an e-book while some still prefer the hard-printed book.

Undoubtedly, e-books do have benefits. Firstly, changes to an electronic publication are relatively easy to make. They are quicker to obtain. E-books are more easily updated. The printed books on many subjects can become outdated very quickly. Secondly, e-books can be easily and quickly kept up to date. You usually get far more than just the e-books. Most e-books are sold with bonuses and related information that usually do not come with the purchase of a printed book. Moreover, they take up less space. Instead of a big library, you can fit literally thousands of books on your computer. It also makes it easier to share this information with families and friends.

For nearly twenty years, additionally, futurists have been predicting the development of printed books. The conventional view has been that digital e-books are on the verge of replacing paper books. However, this has not been the case. A printed book has its advantages too. Firstly, it is an object that can be carried and used alone. It needs no electric outlet (插座), no batteries, nothing. Secondly, e-books will always require some forms of support that the printed book does not need.

I believe that the online publishing has not taken off because people want real books. What is being published online more and more are pamphlets (小册子) and things that really do not need to be in print. These are stuff that people throw away afterward. More often, people do not want to read a book on the computer. What could be better than a paper book? It lasts a long time. These books are designed to last a long time without disappearing.

To sum up, there is no denying that the printed book is still very much preferred over its digital cousins. Reading electronic publications is just not the same when it comes to books. People are still very interested in real books and notebooks.
