A boy was born to a couple after eleven years of marriage. They were a loving couple and loved the boy very much. When the boy was around two years old, one morning the husband saw a medicine bottle open. He was late for work so he asked the wife to cap the bottle and keep it in the cupboard. The mother, preoccupied in the kitchen, totally forgot the matter. The boy saw the bottle and playfully went to the bottle and, fascinated with its color, drank it all. It happened to be a poisonous medicine meant for adults in small dosages . When the child fell down, the mother hurried him to the hospital, where he died. The mother was shocked. She was terrified how to face her husband. When the father came to the hospital and saw the dead child, he looked at his wife and uttered just four words. The husband just said 'I am with you, Darling'. The husband's totally unexpected reaction is active behavior. The child is dead. He can never be brought back to life. There is no point in finding fault with the mother. Besides, if he had taken time to keep the bottle away, this would not have happened. No point in attaching blame. She had also lost her only child. What she needed at that moment was comfort and sympathy from the husband. That is what he gave her. If everyone can look at life with this kind of viewpoint, there would be much fewer problems in the world. Take off all your envies, unforgiveness, selfishness, and fears and you will find things are actually not as difficult as you think. Sometimes we spend time asking who is responsible or whom to blame, whether in a relationship, in a job or with the people we know. By this way we miss out some warmth in human relationship. What did the writer intend to tell us about life? _ . A) Think of nothing and life will be easy B) It is always useless finding who is responsible C) Let go the negative side and we can enjoy life. D) Life should give way to responsibility

As every computer owner knows, when their machines run a complex program they get pretty hot. In fact, cooling the processors can be expensive, especially when you're dealing with huge banks of computer servers. But what if that energy could heat private homes? A Dutch energy firm aims to do just that. Data centers of large Internet firms, such as Google, Apple, Microsoft and others, contain thousands of computer servers. As they process information they generate enormous amounts of heat requiring cooling towers that dissipate it into the atmosphere. A Dutch firm thinks paying for electricity to run the servers and then paying again to cool them is a waste of energy. Boaz Leupe, CEO of the start-up Nerdalize, says it's actually quite simple."We don't actually have to build the data center, which saves a lot of costs in infrastructure and we don't have the cooling overhead, plus that you have the environmental benefit, that the kilowatt hour you are using is used twice, once to heat the home and once to compute the clients task without the cooling overhead," says Leupe. The company developed what it calls an e-Radiator, a computer server that also works as an alternative heating source. Leupe says that five Dutch homeowners are experimentally using them in their homes. "We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, home owners actually get heating for free, and computer users don't have to pay for the overhead of the data center," says Leupe. One of the participants in the year-long experiment, Jan Visser, says the amount of heat produced by e-Radiator depends on the work being done by the server's processors so it cannot be used as the primary source. But he is ready to try it. "If it gives good enough warmth, you can use less of your existing central heating, and there is the chance for a home owner to pay less bills." Nerdalize says e-Radiators generate temperature of up to 55 degrees Celsius and could save up to $440 in... What is NOT true about e-Radiator according to the passage? A) It is a computer server used as an alternative heating source. B) It has been launched onto the market. C) It is environmentally friendly. D) It can save users' money.

Mars 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 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. What matters to the existence of liquid water on Mars? A) The distance from the sun. B) The favorable climate. C) The gravity of the earth D) The salt in it.
