Since the Internet has come into homes，the daily life has never been the same again．But the thing that worries most of us is that we can get viruses from the Internet．Will we catch viruses on our cell phones? A new study in the journal Science says yes，but the spread of such mobile software that can bring harm to our cell phones won’t reach dangerous levels until more cell phones are on the same operating system．
Computers are easily attacked by viruses because they share data，especially over the Internet．Of course，nowadays，more people are using their cell phones more and more frequently．They use them for emailing．text messaging and downloading troublesome ring tones，etc．so it is obvious that cell phone viruses are a threat，as well．
Scientists used nameless call data from more than six million cell phone users to help model a possible outbreak．And they concluded that viruses that spread from phone to phone by Bluetooth are not much concerned．because users have to be in close physical relation for their phones to“see”one another．However, viruses that spread through multimedia messaging services can move much faster，because they can come in．disguise．，such as a cool tune sent by a friend．The good news is that to be effective．these viruses need their victims to all use the same operating system，which not enough of us do，because there is no Microsoft operating system for mobile phones，yet．Thank goodness．

Ifyour recu n．ing(经常性的)dreams are worrying you，you can rest assured and needn’t worry．Psychologists say in the vast maj ority．of these cases，this is just the mind’s way of dealing with stress and conflicts，problems and concerns．It’s a good thing．
They call be surprisingly vivid and real，or fragmented and weird．They can be comforting or frightening．Our dreams can tell us a lot about what we are really thinking．Dreams give us an x—ray of our unconsciousness(潜意识)．The3,tell us，particularly when we are at life’s passages or turning points．
Lisa Oppenheim had the same dream whenever she was about to move to a new home or a new city．It’s always just a feeling of needing to stay safe．Experts say disturbing dreams often occur around major life events．For Lisa，it was moving．For others，it can be marriage or divorce，the death of a loved one or pressure at work．
Doctor Siegel has studied the meaning of dream for nearly 30 years．He believes stressful or upsetting dreams can be a sign of what’s buried deep inside our minds．
He said．“Dreams are important to survival．They are crucial to the balance of our psyche(心灵)．They help us work out problems that we’re having every single day．They go to the cutting edge of what’s stressful，what’s bothering us and what we’re working out in our lives．Dreams can guide us and in order to find that guidance，to find that deep source of wisdom that’s in our dreams every night，we need to pay attention to our dreams．”
But many dreams are scary and horrible．How can we understand these nightmares? Doctor Siegel says they are reflecting especially intense emotion or unresolved conflict．The stronger the emotion in the dream，whether it’s pleasure or fear，the likelier the dream is to be important．
Knowing what your recurring dreams or nightmares mean can be liberating．Some nightmares can be a sign of serious psychological problems，such as post-dramatic stress disorder．If they are extremely disturbing or violent or the cause of sevel’e anxiety，you should see a professional therapist(治疗专家)．
