Finally, you finish all your schoolwork and sit back in your chair. Suddenly you feel a headache and realize your eyes are painful. What’s going on? Doctors say that many students are spending too much time in front of screens, especially during online classes. The following might be of some help to you. |
|
THE 20-20-20 RULE This gives your eyes a break from long screen time. It suggests looking at something at least 20 feet away for 20 seconds after 20 minutes of work on the screen. You can then continue working pain free. |
•Studies show that people blink(眨眼睛) less often when looking at a screen. Keep your eyes wet by blinking often or using eye drops. |
•Sit up straight about an arm’s length(长度) away from the screen. Make sure you’re looking down at your screen. Stand up and exercise often to avoid neck and shoulder pain. |
|
•What about blue light blacking glasses (防蓝光眼镜)? They may look cool, but research shows that blue light isn’t the biggest cause of eye tiredness. So ask doctors about computer glasses before putting them on.

Bananas are the perfect snack． Not only are they sweet and delicious， but they are easy to carry around， so you can take them anywhere． Best of all， bananas provide different things that the human body needs!
Bananas grow best in warm places that get lots of rain． They grow on plants that look like trees． The banana plant， however， is considered a herb rather than a tree because it doesn't have a strong ， woody stem（干，茎）． The plants can grow as high as 30feet． When they reach their full height， flowers grow out from the stem． These flowers produce bananas．
Two or three times each year， the plants produce fruit． The bananas grow together， which seem like "hands"． A hand is made up of 10to 20bananas． Growers sometimes call bananas "fingers"． Each bunch（丛） of bananas has about 15hands， and so a whole bunch may have as many as 200bananas and can weigh more than 100pounds．
After about three months， the bananas are ready to be picked． At this point， they still aren't the sunny yellow color of bananas． Farmers pick them when they're green． That's how they're shipped to stores． They turn yellow along the way and are ready to be sold．
If you love bananas， you've got a lot of company． Americans have been enjoying bananas since the first shipment arrived in the United States in 1876． Today， American eat more bananas than any other fruit． More bananas are sold than apples and grapes together． Every American eats over 26pounds of bananas each year!

Who wants to eat food that is thrown away as waste？ Believe it or not， that's exactly what world leaders did at a lunch held by the United Nations in 2015．
During the meal， the world leaders enjoyed dishes like salads and burgers made with thrown﹣away vegetables and fruits． Chef Dan Barber， who helped create the meal， hoped that the experience would make the leaders pay more attention to the issue of food waste．
It is a huge problem． One out of nine people on Earth does not get enough food． Yet every year over one third of the food produced worldwide goes to waste!
Why is so much food wasted？ Firstly， food is often thrown away before it reaches customers because too much of it is produced， or because it is not kept properly in farms． Secondly， shops and supermarkets usually throw away unsold food． Finally， customers often buy more food than they need， so a lot of uneaten food is wasted．
How can you waste less food？ When eating out， you may ask for less food and take home what is left． Visit fast food restaurant less often， since they usually more wasteful． Encourage your favorite restaurants to give unsold food to food banks．
You can also waste less food at home． Use smaller rice bowls so that you serve less rice．
Encourage family members to use unfinished rice to make rice puddings． Tell family members to make a shopping list and buy only what is on the list when shopping for food．
Food waste is a growing problem and we， either farmers or food sellers or customers， must take this problem more seriously and do what we can to help．

We live in Bedford， a town near London． My father is a hard﹣working pilot， so he doesn't have much time to look after us．
When I was a kid， my mum liked to make breakfast food for dinner every now and then． And I remember one night in particular， when she had made breakfast food after a long， hard day at hospital．
On that evening so long ago， my mum placed a plate of eggs， sausage and terribly burnt biscuits in front of my dad． I remember waiting to see if anyone notices． Yet all my dad did was reach for a biscuit， smile at my mum and ask my brother and me how we had been doing at school． I don't remember what I told him that night， but I do remember watching him put butter and jelly on that biscuit and eat every bite!
When I got up from the table that evening， I remember hearing my mum apologize to my dad for burning the biscuits． And I will never forget what he said，" Honey， I love burnt biscuits．"
Later that night， I went to kiss my dad good night and I asked him if he really liked his biscuits burnt． He wrapped me in his arms and said，" Your mum is really tired after a hard day's work． Besides， a little burnt biscuit could never hurt anyone． We have been married for 17 years． She always cooks for me． Don't put the key to your happiness in someone else's pocked but into your own．"

Copenhagen is one of the best places in the world to be a bicyclist but there is a downside﹣﹣thousands of parked bicycles． Sometimes it gets out of control．
In 2014， when Copenhagen got its Cycle Snake﹣a new bicycle﹣only bridge ﹣the city edged even closer to being a cyclists' paradise．
There are in fact more bicycles in Copenhagen than people， five times as many bicycles as cars， and 400 km of cycle lanes﹣not shared with cars or pedestrians （行人）﹣for a city of about 600，000 people．
This has many advantages， such as cleaner air and physical fitness． If only more thought had gone into what happens when riders get off． Cycle parking is a big problem here．
Bikes are often parked on the pavement， taking up pedestrian space and blocking（堵住） entrances to shops and restaurants．
Outside Copenhagen's central train station， where people often leave their bikes for the weekend， plenty of cyclists are fed up． "There just isn't enough space，" says Kirsten Hoeholt， a famous artiest．
While 95% of cyclists in the city are happy with conditions for cyclists overall， only 29% are satisfied with cycle﹣parking facilities﹣down from 40% in 1996．
One of Copenhagen's is that it has been growing rapidly． About 12，000 people are moving to the city each year， while only 7，000 new cycle parking spaces have been created over the last eight years．
One Dutch idea on its way to Copenhagen is taking away the bikes that are parked in the wrong areas． Leave your bike in the wrong place and you could find that it has been moved to nearby bicycle facilities．
A few years ago "bike﹣butlers" were introduced in some areas． The butlers pick up bicycles that have been knocked over， pump air into flat tyres and give the bike﹣chains a bit of oil， to thank people for parking properly．
