Is your TV connected to the Internet? What about your chair,or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called “Internet of things”.
The Internet of things may be coming sooner than you think. Earlier this year, Aamsung CEO spent a lot of time talking abput the Internet things. He said that five years from now,every Samsung product will be part of the Internet of things,no matter whether it’s a remote control or a washing machine.
So, how do household(家用的) objects that are part of the Internet of things work? Well,think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold.
An Internet-connected camera could help people feel safer in their homes. It can know people’s faces and has an infrared sensr(红外传感器),so even if it’s dark it can see when someone passes by and send you a message on your smartphone to let you know who’s there. If the person is someone you don’t know,it can tell you that ,too.
But according to MIT Technology Roview, whether companies are connecting dog food bowls or security systems to the Internet, there may be some problems. For example, many early connected-home objects don’t have much built-in security, which means they could be hacked(被黑客攻击). Morever, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this ,many companies have joined the Open Interconnect Consortium, which had 45 menbers by late 2014.
So, picture this: you enter your home.The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? I t may happen sooner than you think.What does the article mainly talk about?

Chen Lin is a doctor who is from Hengyang，After his graduation from Peking University，he works in an office for a large organization． And this job can sometimes be just as exciting and dangerous as being an explorer．
Chen Lin works for MSF，an organization also known as Doctors Without Borders（无国界医生）．MSF sends trained doctors all over the world to help people after a war or disaster（灾难）． Chen Lin has traveled to many places to organize programs that help people in need．
At present，there are over 27，000 trained medical staff taking part in MSF projects and tasks．The organization received the Nobel Peace Prize in 1999．All kinds of doctors can volunteer for MSF．They need to be prepared to go almost anywhere in the world and，of course，they should expect difficult conditions．Doctors with experience in tropical （热带的）diseases are especially useful because most of MSF's work is in Africa．When MSF accepts a doctor for a task ，he has to go for at least six months．When doctors have completed a few tasks，they might be sent on an emergency task following a disaster， such as an earthquake．
But why would a doctor leave a comfortable life and a good salary to join MSF？ According to Chen Lin，the experience you have is a great help in your career．Besides，just like the explorers of the past，you need to keep an open mind and learn to get along well with the people you meet． Most importantly，at the end of each task， you have made a real difference to people's lives．

There are plenty of myths（神话） to explain how the world came to have a moon to bring light to the night time． But now there is a plan for a man﹣made moon． It will give us much more light than the natural Moon．
China is preparing to put a man﹣made moon in the sky above Chengdu by the end of 2020．It will reflect sunlight back onto the Earth． If it succeeds， three more such objects will be sent out in 2022，according to Wu Chunfeng， a space scientist． Wu said it would be similar to how we get moonlight， but he predicted（预言） that the man﹣made moon would have eight times the brightness of the real one．
This is because the object will be about 500 kilometers above the Earth． That will make it much closer to us than the moon， which is over 380 ，000 kilometers away，Wu added．
If the plan works， the man﹣made moon will save a lot of power．Scientist predicted that Chengdu could save around 1.2 billion yuan in electricity every year if a new moon lit up 50 square kilometers of the city．And in 2022 ， four man﹣made moons can take turns reflecting sunlight as they will not always be in the best position relative to the Sun． Together， they can give light to an area of up to 6 ，400 square kilometers on the Earth for 24 hours．That means its brightness will be seen in most areas in China，so reducing the need for streetlights．
