I once had a friend who was diagnosed with terminal cancer, and the news that he might only live up to six months was a great shock to him, his family, and his friends. However, in spite of the serious illness, he was initially determined to look into all available treatments that might cure or extend his life. I think that when you find yourself in such situations, you tend to look up every possible way for hope of saving your life.

    As months went on and his health grew worse, I noticed an unexpected change in attitude that came over him. He had also been a happy person with a cheerful personality, but rather than give in to discouragement and self－pity, he took comfort in God and humanity. His talks focused on others rather than himself, and he spoke of the afterlife as something he was prepared for, believing that his concerned ancestors, including his mother and father, were there waiting for him.

    During the last few months, weeks, and days of his life, he was kindly cared for by family, friends, his loving wife, who looked after both his physical and emotional needs, and workers from a local hospice (安养院) came to the home to regulate his medication and provide any other needed support. He didn't complain about his fate, and he willingly allowed others to serve him.

    Indeed, one might think why God allows death and suffering in our world, but for me, such experiences taught me to value family more and kindness for others. You often can't learn these important attributes in the lap of luxury, and perhaps, such an experience is the greatest and final gift the illness can give those left behind.

    For years, people have wondered whether there's life on other planets. Scientists may now be closer than ever to answering that question.

    Using powerful telescopes, a team of astronomers in South America discovered a new planet, called Proxima b. It circles a star named Proxima Centauri, in the same way Earth circles the sun. Proxima Centauri is the closest star to our solar system.

    Scientists believe the new planet has a rocky surface and is similar in size to Earth. More important, they've determined that the distance between Proxima b and its “sun” gives the planet a similar temperature to Earth's.This means it could have liquid water. The presence of water on a planet makes it possible for life to exist there. Scientists refer to planets like Proxima b as “Goldilocks planets” because they are not too hot or too cold, but just right to possibly support life.

    Astronomers have found other Goldilocks planets in the past, but none are as close to Earth as Proxima b. Still, the new planet is 4.2 light years from Earth—that is about 25 trillion miles away.

    Despite the long distance, astronomers hope to get a much better look at our new-found neighbor one day. But they'll need to wait until more advanced telescopes are developed. They may also send a robotic spacecraft to investigate the planet.

    Science fiction writers create imaginary worlds. The way things work in your imaginary worlds will be based on actual science. So it's important for you to be familiar with the scientific principles and inventions that are related to your creation. For example, if you're writing about human living on a planet with zero gravity, then you need to know the effects of zero gravity on the human body.

    Then you have to figure out the exact rules of your imaginary worlds. And you have to follow them. If humans are able to breathe underwater in Chapter 1, your character can't drown in a swimming pool in Chapter 3. The issue here is maintaining your readers' trust. That means the readers are willing to pretend along with you. If you start out with an ordinary detective novel and then throw in someone breathing underwater in the 6th chapter, you will pull the readers out of their imagination. The same thing happens if you change the rules halfway.

    Part of your preparation work for the novel is to map out its worlds in great detail. You should decide the following issues: the history of the world, the geography, what possibilities it offers, how everything works in this new reality, and how all of these factors affect the way your characters think, feel, and react to things. You don't have to tell your readers all the rules in the first chapter. But you have to let readers know enough to understand what's going on. This also allows you to work out logical problems and contradictions before you start writing.

    When you are writing, remember to make it feel real. You are inviting readers to visit a new world. They will want to be able to see, hear, feel, smell, and even taste what it's like. Whether your novel is about a world without disease or an undiscovered planet, help your readers feel like they're actually there.

    The market watchdog(市场监督部门) in northwest China's Xi'an has started a survey into a complaint that a woman's newly bought Mercedes-Benz car has engine oil leaks(漏). The incident has attracted wide attention after a video of a woman sitting on top of a Mercedes-Benz while weeping and arguing with salesmen went viral online. In the video posted on Weibo by a net friend on April 11, the woman said she found an oil leak when she was driving the car home from the 4S store. After she drove the car back, the trader claimed the car had passed all tests before it was sold. She was told she couldn't get her money back nor change a new car for her. All that the trader could offer was to change the engine. The CLS300 car cost around 660,000 yuan($98,445).

    The customer met with officials from the market watchdog of Gaoxin District on Saturday, requesting a full maintenance(维修) history of the car and an independent test by a third-party, Shaanxi TV Station reported.

    Mercedes-Benz issued an announcement on its Weibo account on Saturday, saying it was sorry for the customer's "unpleasant experience". The company has sent a team to Van to help solve the issue.

    Li Yong, an official with the market watchdog of Gaoxin District in Xi'an, told cnwest.com that they learned about the incident online. They are still surveying the incident. They will punish those who are responsible if anything illegal is discovered.

In the movie, The Day After Tomorrow, many climate changes including an ice age are caused by global warming. Much of the science in the movie has been questioned by people. However, there may be some truth to the idea in the movie that global warming could cause an ice age.

The theory starts with an understanding of why Europe and Scandinavia are not colder already. After all, other places at the same latitude(纬度) are covered with ice. The ocean current called the Gulf Stream brings warm waters from the Caribbean to the UK and Europe. These waters warm the countries around their path. This is why the UK, Europe and Scandinavia have a warmer climate than Alaska. Global warming has nothing to do with this. Global warming is significant. It could slow the Gulf Stream, or even stop it. If this were to happen, the cold waters would stay in the area of Europe, the UK, Scandinavia and the Northeastern US. It could mean an ice age for those regions.

Some weaknesses in the Gulf Stream could happen for different reasons. These days, it could happen due to global warming, caused by human activities, such as the burning of fossil fuels.

If a new ice age happened, it would probably be caused by the melting of the polar ice. This will lead large quantities of cold and fresh water to come into the ocean, which would disrupt the Gulf Stream and cause the cooling of many areas that now have a mild climate.

Scientists have gathered a lot of data from the oceans and the land to try to determine whether an ice age could be caused by global warming. With all this information at hand, it appears that it is indeed possible that global warming could lead to an ice age.
