The weather predictions for Asia in 2050 read like a script from a doomsday movie, which has aroused more experts' concern about this serious problem.

Many climatologists and green groups fear they will come true unless there is a concerted global effort to rein in greenhouse gas emission 排放).

In the decades to come, Asia --- home to more than half the world's 6.3 billion people – will lurch (突然傾斜) from one climate extreme to another, with poor farmers battling droughts, floods, disease, food shortages and rising sea levels.

"It's not a pretty picture:' said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam. Global warming and changes to weather patterns are already occurring and there is enough excess carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.

Already, changes are being felt in Asia but worse is likely to come, Sawyer and top climate bodies say, and could lead to mass migration (移民)and widespread humanitarian crises.

According to predictions, glaciers will melt faster, some Pacific and Indian Ocean islands will have to be abandoned or build sea defenses, storms will become more violent and insect and water-borne diseases will move into new areas as the world warms.

All this comes on top of rising populations and increasing demand for food, water and other resources. Experts say environmental degradation(退化)such as deforestation and pollution will likely increase the influences of climate change.

In what could be a foretaste of the future, Japan was hit by a record 10 typhoons and tropical storms in this year, while two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill. The year before, a winter cold snap and a summer heat wave killed more than 2,000 people in India.

Blood donation, also called blood banking, is a wonderful thing to do. It is an easy and direct way to contribute to social work and help the community. It helps to save lives and helps those who are in need of blood due to bad condition or the heavy loss of blood during operations or in accidents.

You are able to give or donate blood every three or four month, and it is a great way to make a huge difference to someone’s life and you can always be proud of it after making valuable contributions to society. Blood donation is not a big problem, but you need to keep a few points in mind.

Before donating blood, make sure that the ferrum (鐵) level in your body is high enough and for that you should take a healthy diet. Do not go for blood donation on an empty stomach. You should follow the correct process so that everything goes well. After having a balanced diet you will feel strong and comfortable to donate blood. Afterwards, you will not feel faint or weak.

For required hemoglobin (血紅蛋白) in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body. For a good blood flow in your body, drink at least 6-7 glasses of water every day. Completely avoid a day before and after giving blood, taking alcohol (酒). Do not smoke half an hour before giving blood.

When you are going for blood donation, be relaxed, which helps keep the right blood pressure. During the blood donation activity, take a deep breath and try to calm yourself. Don’t join in some other activities.

When you donate blood, you are making the effort to save someone’s life. Blood donation is a very simple and fast process, but you need to take care of yourself after donating blood. Proper care helps to reduce side effects. The following are a few tips that will help you out.

Take a rest for 15 minutes after the donation. It helps you to feel relaxed.

Eat something and drink juice before leaving the blood donation centre. Make sure that you have meals after donating blood. Smoking should be avoided for one hour after the process. Avoid some activities right away, for example, driving.

Finally, be proud of yourself because you have done a great thing in helping to save someone’s life. Blood donation is a very important activity.

My old digital camera broke down, so I wanted to buy a new one．Being the cautious type, I fancied a reliable brand．So I went on the Net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store．There in the cupboard was one of the cameras on my list．And it was on special offer．Oh joy．I pointed at it and asked an assistant, "Can I have one of those? " He looked perturbed（ 不安）．"Do you want to try it first? "he said．It didn' t quite sound like a question．"Do I need to?" I replied, "There's nothing wrong with it．" This made him look a bit offended and I started to feel bad．"No, no．But you should try it," he said encouragingly, "Compare it with the others．

I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box．With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time．But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model．

But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice．In the end, I agreed to try the model I had chosen．The assistant seemed a sincere man．So I let him take out my chosen camera from the cupboard, show how it took excellent pictures of my fellow shoppers．．．a(chǎn)nd when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well．Why do we think that new options still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine．
