If your cellphone suddenly stops working, don't blame the service provider.The malfunction might well have been caused by something bigger -- a solar storm.Experts expect that Earth will see more solar activity in the near future.The malfunction of electronic devices will just one of the effects. Sunspots serve as an indicator of the sun's activity.For the past two years, sunspots have mostly been missing.Their absence, the most prolonged in nearly 100 years, has taken even seasoned sun watchers by surprise. When the number of sunspots drops at the end of each 11-year cycle, solar storms die down and all become much calmer. This "solar minimum" doesn't last long. Within a year, sunspots and solar storms begin to build toward a new crescendo, the next solar maximum. What's special about this latest cycle is that the sun is having trouble starting the next solar cycle. The sun began to calm down in late 2007, so no one expected many sunspots in 2008. They should return in 2010. Scientists have predicted that the next solar cycle could be the most active on record: more sunspots and more solar storms. However, sunspots are mostly missing now. Since the earth is in close contact with the sun, strong solar activities can bring trouble to our life. People of the 21st century rely on high-tech systems for the basics of daily life. Air travel and radio communications can be affected by strong solar activities. A big solar storm could cause 20 times more economic damage than Hurricane Katrina. What the sun will do next is beyond our ability to predict. Most astronomers think that the solar cycle will go on but at low level. However, there is also evidence that the sun is losing its ability to produce sunspots. By 2015, they could be gone altogether. We can infer that in the past two years_. A) solar activities have brought much trouble to our life B) the number of sunspots has increased to a large extent C) the solar minimum took the place of the solar maximum D) our cellphones have seldom been interrupted by the solar storm

Instead of a normal court hearing, the trial on Wednesday appeared more like a prepared drama. Hundreds of reporters waited outside the court, in the hope of learning "shocking" information about the case, which includes well-known military singer Li Shuangjiang's son, who gang-raped a woman with another four men on February. The case was not a public hearing because it includes teenagers, whose privacy must be protected under law, but many details had been exposed by the lawyers before the trial. Lawyers of all five suspects and the woman's lawyer made a lot of debate on the Internet before the trial, making the case more confused. Wu Ming'an, a law professor from the China University of Political Science and Law, said it was a pity to see such a "performance" by the lawyers. "It can be understood that the two parties freely spoke their opinions, but it's not professional or wise to see lawyers do the same," Wu said. "Instead, the lawyers should guide and persuade their clients to calm down, especially for such a non-public and sensitive case." China has no clear rule to manage lawyers' behavior before trials, "but it should be general knowledge that the lawyers of the two sides cannot _ too many details, particularly in a case that includes teenagers", Wu added. Yi Shenghua, a lawyer who has been following the case, said it does more harm than good to both parties for such detailed information to be exposed before the trial. "It's OK for lawyers to speak, but what is said must be reasonable and legal. Although judgments should not be affected by public opinion, it's hard for them not to be," he said, suggesting judicial authorities should speak out if the case goes wrongly. Trials must be conducted based on evidence, while lawyers should protect their clients' rights instead of adding fuel to the flames, Yi said. In my eyes, the most important aspect of the case, lies in how to make lawyers do their work more professionally and reasonably. From Yi Shenghua, we know that _ . A) The lawyers' behavior before trials hasn't been ruled. B) It doesn't matter whether the detailed information is exposed before the trial. C) What lawyers say must be reasonable and legal. D) It is hard for judgments to be affected by public opinion.

Can we turn negative thoughts like "I never do anything right" into positive ones like "I can succeed"? Is there power in positive thinking? Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply emphasize how unhappy they are. The study's authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by referring to older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better.If you tell your friend that he may be an Einstein, _ In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write passages opposing funding for the disabled.When they were later praised for their sympathy, they felt even worse about what they had written. In this experiment, Wood, Lee and Perunovic measured 68 students' self-esteem .The participants were then asked to write down their thoughts and feelings for four minutes.Every 15 seconds, one group of students heard a bell.When it rang, they were supposed to tell themselves, "I am lovable." Those with low self-esteem didn't feel better after the experiment.In fact, their moods turned significantly darker than those of members of the control group, who weren't urged to think positive thoughts. The paper provides support for newer forms of psychotherapy that urge people to accept their negative thoughts and feelings rather than fight them.In the fighting, we not only often fail but can make things worse.Meditation techniques, on the contrary, can teach people to put their shortcomings into a large, more realistic perspective .Call it the power of negative thinking. What do we learn from the experiment of Wood, Lee and Perunovic? A) It is important for people to continually improve their self-esteem. B) Thinking positively can bring a positive change to one's mood. C) People with low self-esteem seldom write down their true feelings. D) Forcing a person to think positive thoughts may lower their self-esteem.
