Look at the Earth from.space.Why does our planet look so blue？Its blue because water covers almost three quarters of the Earth's surface.Water is not just an important part of our planet.It is an important part of our body，too.More than half of our total body weight is water.
Our body loses water whenever we exercise or.go to the toilet.That's why we need to drink plenty of water every day.We drink water.We use it to cook，clean，and carry waste out of our homes.Farmers use it to grow vegetables and crops like rice and corn；factories use it to make products.
Since the 1950s，the amount（数量）of water people use has increased by three times.But the water supply（供应）hasn't.Scientists worry that soon there won't be enough water for us，as well as for the animals and plants that share our world.What can we do to help？Use water wisely.
Having enough water isn't our only problem. We also need it clean.
Right now，ships and factories are putting wastes into seas，rivers and so on.Even chemicals that farmers use are running into rivers and lakes.All this pollution can make the water dangerous to drink.It can also harm fish and other water﹣living lives.
We must do something to stop pollution.It's the best way to protect our world's most valuable natural resource（资源）.

Diabetes is caused by a group of metabolic disorders in which there are high blood sugar levels over a long period of time． There are three main types of diabetes：
• Type 1 Diabetes results from the body not having enough insulin．
• Type 2 Diabetes mainly happens to those who do not have enough physical exercise， eat too much unhealthy food and get too heavy．
• Gestational Diabetes is the third main form． It appears when a woman is having a baby． She will probably get well again after the birth of the baby．
Diabetes can bring serious problems． People with diabetes， especially the Type 1， will easily get thirsty and hungry， and quickly lose weight． If it is not treated， it will develop rapidly （weeks or months）， and cause many long﹣term complications． All the complications relate to damage to blood vessels． For example， damage to the eyes． It is caused by damage to the blood vessels in the eyes， and results in gradual vision loss and blindness． The complications will greatly increase the risk of diabetes， by which about 75% of the deaths are caused．
According to a report from the WHO （World Health Organization） in 2015， about 415 million people have diabetes worldwide， which means 8.3% of the adults in the world have diabetes． Of all the cases， 85% to 90% are Type 2 Diabetes． That is to say， most cases of diabetes result from the unhealthy life style． Diabetes doubles a person's risk of early death． From 2012 to 2015， about 1.5 to 5 million deaths each year resulted from this disease． The global economic cost of diabetes in 2014 was around 612 billion USD．
A healthy life style can help prevent diabetes． Doing a lot of physical activities and having a healthy diet will help have normal body weight． Higher levels of physical activity （more than 90 minutes per day） can reduce the risk of diabetes by 28%． Healthy diet includes foods rich in whole grains and fiber， foods with good fats from nuts， vegetable oils and fish， little sugar， and less red meat．

The word culture includes not only the customs of our society， its art， music， but also everyday activities． Cultures give us a sense of belonging in society． So the losing of one's culture is， for many， alarming． Many people believe their traditional ways of life are under threat （威胁）and that something should be done． Yet for some， the losing of culture is a natural result of globalization （全球化）and progress． So is the globalization of culture a threat or a chance？
Those who see globalization as a threat argue that societies are losing special parts of their cultures． For example， Omotik ， a language spoken in east Africa， has only 50 live speakers． There are also increasing fears in China， where the losing of musical and dance traditions， as well as traditional crafts， is causing concern to many． Some argue that it is hard to find differences between London and Tokyo． Young people， whose ideas are often influenced by Western or other popular cultures， often refuse or even give up the traditions their parents grew up with．
Others focus on the advantages of globalization． They accept that Western culture is spreading， but they also point to how Western countries and many other parts of the world are being shown to world cultures． Young Americans enjoy Japanese comic magazines and watch Korean movies． Thai teenagers enjoy pop music from Hong Kong． Many argue that there are advantages to these cross﹣cultural exchanges and that they lead to better understandings between cultures． They say world traditions are celebrated more widely because of these． Chinese New Year， now celebrated in most big cities around the world， is just one of the many festivals that are accepted internationally．
Anyway， many grass﹣roots organizations and governments are making efforts（努力）to protect their cultures． One successful example is Wales． There was a time when social pressures were killing off the Welsh language， but after years of efforts， it is now an active part of Welsh life again． Around the world， similar efforts are going on．

3D printing is becoming more and more popular． We are now able to print things such as clothing， musical instruments and even cars． People and businesses are able to create the things they need very quickly and easily by using 3D printers．
But can you imagine printing food？ Some scientists are trying to change the dining experience completely by doing this． They hope that having a 3D printer in the kitchen will become as common as the blender or microwave． Scientists say that they are easy to use ：you simply have to choose a recipe（食谱） and put the uncooked food "inks" into the printer to make the food you want． This means that it would be very quick and easy to create tasty and healthy meals．
Using 3D printers to create your meals would also be saving the environment． There would be less need for traditional growing， shipping and packaging steps as food production would be a lot quicker and better． For example， tree leaves and insects could be turned into tasty products! Printing food could also help people who have a swallowing（吞咽）trouble． They could program the printer to print softer kinds of their favorite foods so that they would not have difficulty swallowing them．
However， some people think that a future of 3D﹣printed food would be a disaster． It could take away many jobs， including those for growing， shipping and packaging food． Imagine a world where there was no need for farming or growing crops and the same tastes and structures could be printed from an uncooked "food ink "． Traditional cafes and restaurants might lose business， too．Also， there are worries about the healthy value of printed food： is it really possible to get what we need from food﹣based "inks" or something like that？
As we know， cooking and eating together with family and friends has long been a tradition and enjoyable activity． It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button．
