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.

    The term “to extend an olive（橄榄） branch” means to make an offer of peace or reconciliation(和好). This term has Biblical（圣经的）origins, coming from the section of the Old Testament that deals with the flood; the sign that the flood is over is an olive branch brought back to the ark(方舟) by a dove. Olive branches were also symbols of peace in Ancient Greece and Rome, and they continue to be used in various works of art that are meant to suggest peace.

    Some people have suggested that the olive was a very deliberate and well-considered choice as a metaphor(比喻）for peace, because olive trees famously take years to mature. War is typically very hard on the trees because people cannot take the time to nurture them and plant new ones. Therefore, the offer of an olive branch would suggest that someone is tired of war, whether it is an actual war or a falling out between friends.

    In Ancient Greek and Roman times, people would offer actual olive branches. In Rome, for example, defeated armies traditionally carried olive branches to indicate that they were giving in, and the Greeks used them into weddings and other ceremonies. In the modern era, the branch is usually metaphorical, rather than actual, not least because the plants can be a bit difficult to obtain.

    Many people agree that peace negotiations at all levels of society are a good idea. Between nations, obviously, it is important to extend an olive branch to ensure mutual safety and to help the world run more smoothly. This act can also be important on a personal level, as resolving conflict and learning to get along with others is viewed as an important life skill in many cultures.

    At some point in their lives, many people will be advised to extend an olive branch to settle a dispute or resolve an issue. Some people believe that it takes an immense amount of courage to take this action, as it often comes with an admission of wrongdoing and regret.

    Recycling: Beyond the Dustbin

    Recycling is very important and necessary in today's world. the most important reason for this is that human progress and industry have made it possible for people to have lots of things, and when people have many material possessions, they are bound to throw some of them away.  Recycling is a way for us to keep the world clean as items are broken down and used again, preventing littering in the environment. Instead of throwing all your garbage into the dustbin, you should separate paper, metal, glass, and plastic into different containers.  They can be turned into valuable compost, which is the perfect food for plants.  

     You can tell if an item has been made from recycled materials by its label. If it is made with recycled materials, it will say so. Also instead of always buying new clothes, you can arrange to have a clothing exchange with your friends. You bring clothes you don't want and pick items you want from what other people have brought. Not only does this save the environment, but it also saves your money.  This saying can be applied to all sorts of things: books, CDs, furniture, etc. Also try shopping at second-hand stores, because they often have lots of items still in good shape for you to choose.  

    Many countries have made it easy for people to recycle, as alongside the normal garbage trucks or special garbage trucks come and are there ready to be used. However, some countries leave it to the ordinary people to recycle.  Recycling represents just one way in which we can help the environment, but it is an effective one.  

A. Fallen leaves can also be recycled.

B. Having too many things causes a lot of garbage.

C. You should try to buy products that are made with recycled materials.

F. Remember, what is one person's unwanted object can be someone else's treasure!

G. It needs more attention in society so we can continue to make our environment livable.

In the 1990s, a large number of stone remains were found in the lake, which led to a series of underwater research. Traces (踪迹) of ancient constructions were discovered, but their origins are still unknown.

The word "Pu'er" may remind many of the famous tea from Yunnan Province. Back in the ancient China, this region also served as an important stop along the trade route—Tea Horse Road. This has much to do with its location. The Sun-River National Park here is highly recommended if you are looking for some fresh air and a close encounter with nature. The rainforests in the park provide habitats for over 800 animal species and 2, 000 different plants.
