Emergencies can happen anytime, so being prepared for a home first-aid kit(成套工具) is important to your family. Having a proper one in your home is an easy but necessary part of good emergency preparation.

Pick a good container

One good choice is a large translucent plastic container, which makes it easy to see the materials inside. Lunchboxes are also another good choice. Basically, if it's big enough, and at least somewhat water-resistant, it can make a good container. Regardless of your container choice, it should be easy to recognize, so write "FIRST AID" on it with a marker.

Teach your family about the kit

For younger children who shouldn't use the items in the kit, teach them where it's located, so they could show a visitor, relative or babysitter. For older children and adults, instruct them how to use the items in it. Use a first-aid instruction booklet, like those available from the American Red Cross for guidance, and place the booklet in the kit for reference.

Keep your kit up-to-date

No one wants to fetch a first-aid kit and find the bandage box empty or the pain relievers expired(过期的). Keep track of supply amounts and expiration dates regularly.

Create a checklist in the kit

Record every item on a sheet of paper and keep it in the kit. Besides, record the amount of the items and expiration dates next to the listed items on the checklist that you include in your kit. In this way, anyone who wants to reach the kit can immediately know what it includes and doesn't include. Also, they can be clear whether the items can be used.

Having attended a first-aid-at-work course, Brian Cracknell soon found himself responding to two emergencies in a week.

Brian was at work in his bus company office in Weston-super-Mare on May 18 when a colleague called to say there had been an accident at a bus stop nearby. He ran to the scene with his first-aid kit and found an old lady sitting at the bus stop. When boarding (上车) the bus, the old lady painfully hurt her left leg, which was bleeding.

He introduced himself, and asked some basic first-aid questions to get a general picture of her health. Then he put his jacket on the floor, using the lady's coat as a pillow, and gently laid her down so he could raise her legs and apply some bandages. Brian said, "At first I was a bit worried about remembering to do all the right things. I made sure she was as comfortable as possible." When he had nearly finished, he told the lady that she was his first one. The lady said he was doing a great job.

Just a week later, Brian got a second call-out to help another lady at a bus stop.

Having used his new skills twice within a short time, Brian has decided to sign up as a Red Cross first-aid volunteer. He said, "I just thought: What's the point of having this knowledge if I'm not going to use it? It felt really good to help those people. I was so proud of myself afterwards, so I'm going to join the Red Cross."

Do you live in a city? You've probably noticed how noisy and crowded life in a city can be. What if you could live next to a calm lake instead?

As it turns out, living near bodies of water—lakes, rivers, ponds, even oceans—can help us feel both happier and healthier. Those who live less than a kilometer from the coast are around 22 percent less likely to have mental health problems than those who live 50 kilometers or more away, according to a study by researchers from the University of Exeter, the UK. People who visit the coast at least twice a week tend to experience better general and mental health as well.

So how does "blue space" make us feel better? For one thing, aquatic environments tend to have less pollution and more sunlight, both of which are linked to better mental and physical health. People who get more sun tend to be happier than those who do not.

There's also air above the sea. After spending time near the ocean, you might find that you feel more relaxed than usual. This is because sea air is filled with negative ions(负离子). These ions balance our levels of serotonin(血清素), a chemical that affects our moods. With balanced serotonin levels, we feel more calm and relaxed, according to the Daily Mail.

Finally, people who live near water tend to be more physically active, according to The Guardian. Water sports like swimming and rowing can help us stay in shape, which in turn keeps us healthy.

Dogs wag(摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.

Researchers in Italy examined the tail wagging behavior of 30 dogs, catching their responses to a range of stimuli(刺激物) with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow them to view various stimuli. They were tested one at a time.

The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—a positive experience—their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less excitement again. The appearance of a large unfamiliar dog, similar to a German shepherd dog, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of a video, it was thought that the findings could help people judge the mood (心情) of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.

Imagine that you are in a remote village somewhere with no medical clinic.  Once the doctors get to you, they examine you and take blood samples, but they won't be able to help you until they take the samples back to the hospital to find out what is wrong. Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic(诊断的) tool.

Ozcan's invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, don't have enough training to accurately interpret what they see.  With Ozcan's mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at the hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes. 

 His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.

By inventing a medical tool that uses existing technology, Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effectively applied almost anywhere.

CPR is an effective form of first aid (give) to the victim whose heart suddenly stops.

Doing it can increase the chance of the victim's (survive). So knowing CPR can be a real lifesaver. 

How to give CPR? There are (simple) three steps. Firstly, roll the victim over onto his back and do the chest compression(按压).  this way, it keeps blood flowing to the brain, heart and other organs. To perform the compression, place one hand over  other and press firmly on the victim's chest many times in a row, (push) at least 2 inches deep on every compression. Then after the compression (complete), check the airway (see) whether the person is breathing. If not, perform mouth-to-mouth,  helps to deliver oxygen to the victim's lungs. And the chest compression should start again right after two breaths are given.

Learn CPR, for you never know when you might need . And it feels good to know that you could help in an emergency.

A funny thing happened to Arthur when he was on the way to work one day. As he walked along Park Avenue near the First National Bank, he heard the sound of someone trying to start a car. He tried again and again but couldn't get the car moving. Arthur turned and looked inside at the face of a young man who looked worried. Arthur stopped and said, "It looks like you've got a problem."

"I'm afraid so. I'm in a big hurry but I can't start my car."

"Is there something I can do to help?" Arthur asked. The young man looked at the two suitcases in the back seat and then said, "Thanks. If you're sure it wouldn't be too much trouble, you could help me get these suitcases into a taxi."

"No trouble at all. I'd be glad to help."

The young man got out and took one of the suitcases from the back seat. After placing it on the ground, he turned to get the other one. Just as Arthur picked up the first suitcase and started walking, he heard the long loud noise of an alarm.

It was from the bank. There had been a robbery(抢劫)!

Park Avenue had been quiet a moment before. Now the air was filled with the sound of the alarm and the shouts of people running from all directions. Cars stopped and the passengers joined the crowd in front of the bank. People asked each other, "What happened?" But everyone had a different answer.

Arthur, still carrying the suitcase, turned to look at the bank and walked right into a young woman in front of him.

She looked at the suitcase and then at him. Arthur was surprised. "Why is she looking at me like that?" he thought. "The suitcase! She thinks I'm the bank thief!"

Arthur looked around at the crowd of people. He became frightened, and without another thought, he started to run.
