1 . Not only does “global warming” bring about an increase in the world's temperature， but also it causes sea levels to rise, which has resulted in the first escape of an island nation． The citizens of Tuvalu will have to leave their homeland.
During the 20th century, the sea level rose 8﹣12 inches. As a result, Tuvalu has experienced lowland flooding of salt water that has polluted the country's drinking water.
Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation has suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol an international agreement calling for industrialized nations to reduce their greenhouse gas emissions, which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluan's to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.
Tuvalu is not the only country that is vulnerable（易受影响的） to rising sea levels, Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”.

2 . Those who are concerned that robots are taking over the world can rest easy—for now. Though the androids have proved useful at performing ordinary tasks, they are not ready for the greatest time. At least that appears to be the case at Japan’s Henn-na Hotel chain where over half of the robot staff are being replaced by humans.
The first location of the unique hotel opened in July 2015 was at Nagasaki’s Huis Ten Bosch Theme Park. The hotel’s owner, Hideo Sawada, promised the hotel to be managed primarily by robots. Guests were greeted and checked-in by a dinosaur robot, while a cute android called Churi, placed inside each room, provided information about attractions. Not surprisingly, the lodging, recognized in 2016 as the world’s first robot-staffed hotel by Guinness World Records, drew in curious visitors from all around the world.
But as the years have passed, the hotel’s main draw is becoming less novel and more unsatisfactory. Also as the robots are “aging”, they are costing more to repair. Among the 283 androids being replaced are the chain’s two dinosaur receptionists. In addition to scaring young guests, they are also unable to photocopy guests’ passports, forcing human employees to step in each time. Also out are the cute Churi robots, which annoyed guests by interrupting their conversations. For example, one guest told The Wall Street Journal that Churi mistook his snoring for a command and kept asking him to repeat his request all night.
Sawada told The Wall Street Journal, “When you actually use robots you realize there are places where they aren’t needed—or just annoy people.” While Sawada may be cutting back on his use of androids, the recently-opened Smart LYZ Hotel and the Fly Zoo Hotel in China, are run entirely by robots, with not a human in sight. Whether the employees have more competence than those “hired” by the Henn-na Hotel chain remains to be seen.

3 . Mars(火星) appears to be flowing with small streams of salty water, at least in the summer, scientists reported Monday. “It suggests that it would be possible for there to be life today on Mars,” NASA’s science mission chief, John Grunsfeld, said at a news conference on September 28, 2015.
The streams are about 12 to 15 feet wide and 300 feet or more long, scientists said. “What we’re dealing with is wet soil, thin layers of wet soil, not standing water,” said Aifred McEwen of the University of Arizona at Tueson, the principal scientist for the Mars Reconnaissance Orbiter’s high-resolution imaging experiment.
Because liquid water is essential to life, the findings could have major implications for the possibility of Martian life. The researchers said further exploration is needed to determine whether microscopic life exists on the planet.
The presence of liquid water could also make life easier for astronauts visiting or living on Mars. Water could be used for drinking and for creating oxygen and rocket fuel. NASA’s goal is to send humans there in the 2030s.
The evidence of flowing water consists largely of dark, narrow streaks(条痕) on the surface that tend to appear and grow during the warmest Martian months and fade the rest of the year.
Mars is extremely cold even in summer, and the streaks are in places where the temperature is as low as minus 10 degrees Fahrenheit. But salt can lower the freezing point of water and melt ice.
The source of the water is a mystery. Scientists noted it could be melting ice. It could be an underground aquifer, which is rock or sand that can hold water. It is possibly water vapor from the thin Martian atmosphere. Or it may be a combination Michael Meyer, lead scientist for NASA’s Mars exploration program, said the only definitive way for now to determine whether there’s life on Mars is to collect rocks and soil for analysis on Earth—something a U. S. lander set for lift-off in 2020 will do.

There is too many people and too many pollution on the earth. If we moved to the moon one day，how would life be like there?
In my opinion, life would be much more comfort on the moon than on the earth. There wouldn't be pollution or traffic jam. We could go wherever we like in one minute by the spaceship, which would be much fast than a train or an airplane. We would eat whatever you like without being concerned unhealthy ingredients. This is a place where I am always dreaming about.
