9．Why can some people sleep through noises like a honking car or flushing toilet，while others are awakened by the lightest sound？
To find the answer，sleep researchers at Massachusetts General Hospital conducted an unusual study of 12self-described deep sleepers．After tests confirmed that the healthy volunteers were solid sleepers，they took part in a three-night study in the university's sleep laboratory．The participants spent the night in a big and comfortable room．But the room also included four speakers positioned near the top of the bed．
During the night，the deep sleepers were subjected to 14different recorded sounds，like street traffic，toilets flushing，an ice machine dispensing and an airplane flying overhead．Next door，the researchers monitored their sleep patterns and brain waves．
As expected，all of the participants slept relatively well，but there were differences in how they responded to the noisy interruptions．Some of the sleepers didn't wake up even when a sound was blasted at 70decibels （分贝）； others were awakened by sounds at 40or 50decibels．
The researchers discovered that the difference in a sleeper's reaction to noise could be predicted by the level of brain activity called"sleep spindles''．A sleep spindle is a burst of high-frequency brain activity coming from deep inside the brain during sleep．The source of the spindles is the thalamus，a part of the brain that sends sensory information to the rest of the cortex （皮层）．
Before the study，the Massachusetts researchers theorized （推理） that the spindles are the brain's way of preventing sensory information from passing through the thalamus and waking the rest of the brain during sleep．They found that the sleepers who experienced the most sleep spindles during the night were also the soundest sleepers and were least likely to be awakened by noise．
Scientists already know that most people become lighter sleepers with age，most likely because older people experience less"slow wave sleep''，which is the deepest stage of sleep．People also produce fewer sleep spindles as they age．But even when controlling for the stage of sleep a person was in，the number of sleep spindles still predicted their risk for awakening because of noise．
More research is needed，but the findings suggest that a better understanding of sleep spindles could lead to new behavioral or drug therapies for people with sleep disorders．For instance，future studies may try to determine whether diet，exercise or other behaviors may influence the number of sleep spindles a person produces during the night．

63．Some participants can sleep well through loud noises mainly becauseB．
A．their brains don't respond to outside noises
B．their brains react differently to noises
C．they adapt to the environment quickly
D．they don't pay attention to the monitors
64．Scientists believe that the key to affecting deep sleep isA．
A．sleep spindles B．stages of sleep C．sleep disorders D．sensory information
65．It can be learned from the passage thatB．
A．the older a deep sleeper becomes，the lighter his sleep must be
B．the more"slow wave sleep"one experiences，the deeper sleep one has
C．the more frequently a sleeper's brain works，the less information it sends
D．the deeper sleep people have，the more likely they will be awakened by noise
66．From the passage we can predictA．
A．more factors in influencing sleep spindles may be discovered
B．more solid sleepers will take part in relative experiments
C．sleep spindles will be applied to changing one's behaviors
D．deep sleepers will probably enjoy a more healthy life．

11．First lady Michelle Obama turns 50on Friday，Jan.17，2014．
Michelle Obama has spent the first half-century of her life breaking barriers and checking off a series of firsts．Now，as she reaches her milestone birthday Friday，the nation will be watching to see in what other areas she will leave her mark．
Five years after moving into the White House，and without a re-election campaign to worry about，she has more room to relax in her role and，political watchers say，possibly become more vocal （声音的） on political issues in the three years left in office．
So far，critics have complained about Michelle's silence on issues where they expected to hear her voice：Last year，at the start of her husband's second term，she disappointed advocates for tighter gun-control measures after she failed to push harder on the issue in response to the massacre （残杀） at Sandy Hook Elementary School in Newtown，Conn．She also disappointed some feminists （女权主义者） who wanted her to defend their causes instead of falling back on her self-described role as the nation's"mom-in-chief．"Nor did she handle racial issues during her second term，as some had expected．
"The most important thing to remember is，whether you are black，white or Hispanic，you're the first lady and the president of all the people in the United States．That's a huge melting pot，so to reinforce （强化）that she's African American over anything else would not be wise，"said Anita McBride，who directs programming and national conferences on the legacies （遗产） of America's first ladies and their historical influence at American University．
Valerie Jarrett，a top White House adviser and a close friend of the Obamas，said the first lady doesn't want to "spread herself too thin．"
"She really wants to have a maximum impact and to do that in fewer areas，"Jarrett told the Associated Press．"That，she said，"is better than trying to take on every single possible cause．"
But Robert Watson，a Lynn University professor，said he expects Obama to"go a little harder at issues"over the next several years．"Second-term first ladies usually feel more at ease to speak more forcefully about issues close to their heart，"he said．
Myra Gutin，a Ryder University communications professor and frequent lecturer on first ladies，said she expects Obama to continue making both of them a priority in her remaining years in the White House，given their success．Michelle launched the"Let's Move"campaign in 2010．It in particular has gained widespread support，ranging from the National Football League to the Sesame Street franchise （特许），which even gave permission to the produce industry to use its licensed characters for free on fruits and vegetables．
"There's no such thing as a traditional first lady，not anymore in this technology-filled world．Is Mrs．Obama cutting edge？Is she an activist？No．As first ladies go，I think she's been politically careful because she does not want there to be a major flare-up that would require her husband to use his political capital to clean up，"she said．"But she's not exactly just sitting in the White House pouring tea and having receptions，either．"

A．It's not wise to reinforce Michelle is African American over anything else．

D．It's a tradition for first ladies to stay out of political issues．
