What would you do if you see someone hurt badly? The following will help you to learn some important skills to give casualty (伤员) first aid.

{#blank#}1{#/blank#}

The first and most important thing you must do is to make sure the place is not dangerous. Can you see anything that might not be helpful to you? Can you hear anything that could be dangerous?

{#blank#}2{#/blank#}

When you see someone has been hurt, you may feel scared. If you feel yourself starting to be nervous, try to calm yourself down. For example, talk to people you trust about what happened, and you'll be relaxed.

When someone needs first aid, talking to him will help him to stay calm and feel safe. Even if he does not answer you, you should still tell him what you are doing. It will let him know that you are helping him.

Sometimes, the casualty will need more help than you are able to give. The best thing you can do is to phone some people for help. They can give you some useful advice or offer you some help.

There are also many other things to do. Try your best to help the casualty. Asking people around you for help is really better than waiting for doctors. Besides, you can also try to keep in touch with his families and friends.

More and more scientists are interested in learning about dinosaurs. They want to find out the reasons why dinosaurs died out.

Most scientists think that millions of years ago, dinosaurs lived on the earth happily and safely because the {#blank#}1{#/blank#} earth was warm and wet. At that time, there were rain forests everywhere. Dinosaurs could easily find enough food. About 95 million years ago, most of the earth became cold and dry because a little planet hit the earth heavily. As a result, almost all the forests {#blank#}2{#/blank#}. The dinosaurs couldn't find enough food, so most of them died.

However, other scientists don't think so. Some of them think fighting between the animals is the main {#blank#}3{#/blank#} for the dinosaurs' death. At that time, there were also many {#blank#}4{#/blank#} between dinosaurs. Another reason is that they think about 95 million years ago some new kinds of animals with big brains came to the earth and they killed many dinosaurs. Although these happened more than 100 million years ago, we can tell by the animals' {#blank#}5{#/blank#} they left.

Technology has changed the way we live and especially the way we work. For many jobs, workers no longer need to be in the office building. People can telework: they can work at home or in any place where they can use the necessary technology. 

It is easy to think that this freedom of working is good for workers and for families. But as it turns out, teleworking is both good and bad. A new report looks at the advantages and disadvantages of teleworking at home. It looks at 15 countries including Argentina, Brazil, India, Japan, the United States and 10 European nations. 

According to Vargas, the lead author of the report, the study finds that about 20% of people in Europe who work in an office are reported to have high levels of stress. However, there are over 40% of stressed-out people in Europe among those who deal with busy work at home. He says those stressed-out people who work at home have trouble sleeping. The report also shows that teleworkers say that they often work alone and are likely to work longer than in the office. 

But the report also says there are advantages for those who telework part-time, or not all the time. It says this is good not only for the workers, but also for leaders and companies. " The findings show that if workers do it on a part-time basis, this way of working can turn out to be positive results for workers, leaders and companies. " The report adds, " Two or three days per week seems to be the sweet spot. " Half the time in the office and half the time outside the office seems to be perfect. 

Vargas explains that many organisations have developed some working rules to solve this problem. They set maximum(最大量) numbers of days per week, during which people can work outside the work-site. Usually, workers are able to telework two or three days a week.
