1). The Fat Killing Drug■Most obesity drugs burn fat by suppressing appetite or speeding up metabolism(新陳代謝).But a new drug recently having been tested on obese monkeys gets further progress.It is reported “kills” fat cells.Researchers from the University of Texas think the drug could kill fat in humans in future.■What is the fat klling drug？ The experimental drug works to kill the cells found in white adipose tssue，says Steven Reinberg from USA Today.The drug kills fat “by a synthetic(合成的) protein which causes the cell to die”.Then，the body will reabsorb those dead cells.■And will it make these fat monkeys too thin？ Thinner，in fact.In just 5 weeks，12percent of weight was lost from these obese monkeys’ body.The monkeys also shed (流失)30 percent of their abdominal fat，says Dr.Tim Bauer，“monkeys that were already thin didn’t shed pounds at all，that’s to say，it might only target extra weight，not the stuff we need to survive.”■Would this be efctee on humans？ Yes！ Usually，fat burning drugs are tested on mice.Researchers believe this research is particularly“relevant because it was done with primates (靈長類)”says Louise Calvino from Fox Medical.What’s more，the fatter monkeys in the study had grown portly (肥胖的) because of their own overeating and seldom exercise一just like many obese humans.Researchers think the drug could not fight obesity in humans.( )

2). What Is an Anxiety？■Anxiety is a natural human reaction that involves the mind and body.It serves an important basic survival function：anxiety is an alarm system that is activated whenever a person perceives danger or threat.■When the body and mind react to danger or threat，a person feels physical sensations of anxiety-things like a faster heartbeat and breathing，tense muscles，sweaty palms，a queasy stomach，and trembling hands or legs.These sensations are part of the body’s fight-flight response(逃避反應(yīng)).They are caused by a rush of adrenaline(腎上腺素) and other chemicals that prepare the body to make a quick getaway from danger.They can be mild or extreme.■The fight-flight response happens instantly when a person senses a threat.It takes a few seconds longer for the thinking part of the brain (the cortex) to process the situation and evaluate whether the threat is real，and if so，how to handle it.If the cortex(皮層) sends the all-clear signal，the fight flight response is deactivated and the nervous system can relax.■If the mind reasons that a threat might last，feelings of anxiety might linger，keeping the person alert.Physical sensations such as rapid，shallow breathing；a pounding heart；tense muscles；and sweaty palms might continue，too.If you keep alert for a long time，you may feel tired and won’t be anxious.( )
