Nowadays, we are having a much busier life, and we are using our eyes more than ever before. So we often have tired eyes after a day’s work or study. Here are some good methods of protecting eyes against tiredness to keep them healthy.
POSTURE(坐姿)
Get into the habit of paying attention to the way you sit. Try to stick to the proper posture that doctors suggest.
HELPFUL PICTURES
There are some special pictures online that can help relax your eyes. You may download such pictures to your computer or smart phone. When there is nothing far away you can look at to relax your eyes, you can use one of these pictures. A picture with something like a tunnel(隧道)in it is quite popular. Try to look as far into the tunnel as you can for 30 seconds(秒). Do you feel better?
BREAKS
The 20-20-20 rule: take a break from the screen every 20 minutes for 20 seconds and look at something 20 feet(about 6 meters)away.
EYE EXERCISES
Step 1. Sitting comfortably, imagine there is a clock in front of you and turn your eyes up to 12 o’clock. Pause(停顿)for a second, and then lower your eyes to 6 o’clock. Pause again, and then repeat this step 10 times. Complete the exercise by cupping your hands over your eyes for a few seconds, letting them rest in the darkness.
Step 2. Look at something on the right. Keep your eyes on it and slowly turn your head to the left as far as possible. Then do the same thing on the left. Repeat the exercise a couple of times.
Step 3. Hold your finger in front of your nose and keep looking at it. Slowly move the finger towards yourself as close as you can without losing focus(焦点). Then look outside the window as far as possible. Repeat this several times.
SPORTS
Table tennis is about a small ball traveling at high speed—the best sport to train your eyes and relax the muscles(肌肉)in and around the eyes. Other sports like tennis, badminton and kite flying are also great for relaxing tired eyes.

Changing a light bulb can be dangerous. With some lights you cannot be sure whether the power is on or off. Before changing a light bulb, follow these tips.
You will need:
● A replacement light bulb. Know beforehand if the fitting needs a screw-mount (螺口) or a bayonet-mount (插口) bulb.
● A ladder or strong object to stand on, such as a wooden box, if the bulb is in a high ceiling.
● An assistant, if the light bulb has to be removed from a high-ceiling fitting.
Note: Change the bulb during daylight so that you can clearly see what you are doing.
Step 1 Make sure to turn off the light or lamp at the wall. You then know that the light will not be turned on—it can be surprising and dangerous if the light comes on in your hands as you plug (插入) the new bulb in!
Step 2 If you are replacing a working bulb with another type of bulb, allow a hot bulb to cool before touching it.
Step 3 If you have to use a ladder for an overhead light, have an assistant hold the ladder steady. The assistant can take the removed bulb and pass up the replacement bulb, which saves unnecessary messing with while on the ladder.
Step 4 For bayonet-fitting bulbs: using your hand, put a little upward pressure on the glass bulb, and turn it anticlockwise (逆时针旋转) (as you look up at it). It will unlock the bulb shank (插槽) from the metal frame. The bulb will come out downwards.
For screw-fitting bulbs: grasp the bulb firmly and turn anticlockwise until it is freed from the socket.
Step 5 Insert a replacement bulb lightly and firmly into the socket, and turn it clockwise (顺时针) until it’s snug. It is the opposite process to removing a bulb.
Step 6 Turn the light on to check that the bulb works and it has been correctly installed.
Step 7 Deal with the used bulb properly. Old bulbs are not recycled with other glass.
1. How many types of light bulbs do these instructions apply to?A.One. | B.Two. | C.Three. | D.Four. |
A.Safety. | B.Convenience. | C.Speed. | D.Quality. |
A.make sure to turn off the power before starting |
B.test the new bulb after the old bulb has been replaced |
C.be sure the safety and effectiveness of the person on the ladder |
D.get medical help in case of an accident or emergency |
A.unlock the bulb shank from the metal frame | B.apply upward pressure on the bulb |

In some places,the sun isn’t hot enough,or it doesn’t shine every day. In these places, other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling (煮沸)sea water with high heat, a lot of fresh water can be made quickly.

【推荐3】Nobody wants to lose, but we must accept that losing is a part of life. After all, we can’t win all the time. However, we can learn something valuable from every failure (失败). This may help us succeed in the future. So we must know how to be a good loser.
We must not be afraid of losing. When we lose, just take it with a smile and look on the bright side of it. Failure can’t be avoided in our life. Edison failed 10,000 times before he invented the light bulb (灯泡). When he was asked how he felt, he said that he hadn’t failed 10,000 times but had learned 10,000 things which didn’t work. We must know that history is full of examples of men and women who achieved success although they failed many times.
Losing is not very disgraceful. We must accent our failure and learn to take advantage of it. Remember that it can be helpful. Take action to walk out of it. When we lose, think about what we did and how we can improve. If someone else can help, we’ll be lucky enough. Maybe he or she has been through the same experience before. Many people enjoy helping others solve problems. This can save us a lot of time in learning how to avoid the same mistakes in the future.
We should face our failure when we lose. There is only one winner in every competition. Some win, while some lose. That is a usual way of life. If we offer our congratulations to the winners and share in their happiness, we won’t feel sorry for our failure.
In a word, being a good loser will help us to succeed in life. It might be painful at the beginning, but there are many advantages. Good losers set examples to us, and most importantly, they finally win.

【推荐1】Artists Heather Peak and Ivan Morison have changed a school bus into a traveling place for studying the sky, weather and space. It’s called the Moon Palace.
The Moon Palace was built in memory of John Smeaton, who was born in Leeds the UK on June 8, 1724. John Smeaton was a famous civil engineer (土木工程师). He believed in using civil engineering to help everyone in society. He also had many interests, from building lighthouses to reading poems. And he was very interested in studying planets and stars.
The Moon Palace tours around Leeds from August to December 2023. This project encourages people to think and explore like Smeaton. Visitors to the Moon Palace can look up at the night sky through telescopes (望远镜) and learn something about planets and stars. Or they can just pick up a book, talk to others on the bus.
The creative director of the project, Abby Dix-Mason, said that Smeaton’s work changed people’s life but he never showed off. “Smeaton was all about making the world better for everyone,” said Dix-Mason.

【推荐2】Food waste is a big problem around the world. While some people throw away unwanted food, lots of people in other parts of the world face food shortages(短缺).
Because of this problem, many countries in the world like Germany and France have set up food banks. People and grocery stores(杂货店) who have enough food can give extra food to them, then they can give the food to those in need. Shanghai Oasis opened China’s first food bank in 2015. In five years, it saved seven million tons of food and helped 760,000 people.
Many fruits and vegetables go to waste because they look ugly. For example, about 25 to 30 percent of carrots don’t make it to the store because of their looks. So try to buy ugly food next time, since it is just as good as “normal” food.
Many Chinese restaurants are telling people to order dishes by using the “N-1” formula (方案). “N”stands for the number of people in your group. So if you’re in a group of six people, you should order five dishes.
It is a shame to waste food. But everyone can do something to make a difference.

Sometimes, people also don’t say exactly what they mean. For example, when someone asks “Do you agree?” the other person might think, “No, I disagree. I think you’re wrong…” But it isn’t very polite to disagree so strongly, so the other person might say “I’m not sure.” It’s a nicer way to say that you don’t agree with someone.
People also don’t say exactly what they are thinking when they finish talking with other people. For example, may talks over the phone finish when one person says “I’ve to go now.” Often, the person who wants to hang up gives an excuse “Someone’s at the door.” “Something is burning on the stove.” The excuses might be real, or not.
Whether they are greeting each other, talking about an idea, or finishing a talk, people don’t say exactly that they are thinking. It’s an important way that people try to be nice to each other, and it’s part of the rule of the game of language.
