7．Doctors sometimes prescribe light therapy to treat a form of depression in people who get too little morning sun．But too much light at other times may actually cause such mood disorders． Long-lasting exposure to light at night brings depression，a new study finds，at least in animals．
The new data confirm observations from studies of people who work night shifts，says Richard Stevens of the University of Connecticut Health Center．Mood disorders join a growing list of problems，including cancer，obesity and diabetes梩hat can occur when light throws life out of balance by disturbing the biological clock and its timing of daily rhythms．
In the new study，Tracy Bedrosian and Randy Nelson of Ohio State University exposed mice to normal light and dark cycles for four weeks．For the next four weeks，half of the mice remained on this schedule，and the rest received continuous dim light throughout their night．Compared with mice exposed to normal nighttime darkness，those getting dim light at night lost their strong preference for sweet drinks，"a sign they no longer get pleasure out of activities they once enjoyed，"Bedrosian says．
In a second test，mice were clocked on how long they actively tried to escape a pool of water． Those exposed to night lights stopped struggling and just floated in the water，a sign of"behavioral despair"，10times as long as the mice that had experienced normal nighttime darkness．All symptoms of depression disappeared within two weeks of the mice returning to a normal light-dark cycle，the researchers report．The scientists also could quash the behavioral symptoms by injecting （注射） the brains of animals with a drug that prohibits the activity of certain molecules linked with human depression．This finding further suggests that light at night may cause something related to depression．
Human studies linking nighttime light and mood disorders are important but can't easily detect molecular underpinnings （分子基础） as animal studies can，says George Brainard of Thomas Jefferson University．The new work，he says，suggests that the change of the biological clock by light at night can be"an extremely powerful force in regulating biology and behavior．

63．After being exposed to continuous nighttime light，the miceD．
A．changed their preferences           B．escaped from the water more eagerly
C．remained active as before           D．showed less interest in their favorites

66．What is the main idea of the passage？A

B．A drug has been found to cure mood disorders．
C．The study on animals can be applied to humans．
D．Human biological clock can be controlled by lieht．

8．Do you often feel tired in the morning even though you've been in bed for seven or eight hours the night before？Like many people，you are not sleeping as much as you think you are．In other words，your sleep efficiency is not that good．
Sleep experts define"sleep efficiency"as the percentage of time lying down that you are actually sleeping．According to journalism website Vox．com，the science of sleep efficiency is still young．There is no specific number for efficiency that's been proven as linked to poor health．However，according to a New York Times report about sleep quality，some experts estimate a rough range of 85percent or above as a reasonable place to be．Therefore，some tips for improving sleep efficiency are as follows：
Keep a consistent（一致的） sleep schedule
Go to bed and wake up at the same time，or relatively the same time，every day．Consistency is key to a good night's sleep，especially when it comes to waking up．When you have a consistent wake-up time，your brain adapts to this and moves through the sleep cycle in preparation for you to feel rested and alert at your wakeup time．
Avoid blue light at night
Blue light given off by the screens of computers，iPads and smartphones makes you feel more alert．Blue light tells your brain it's daytime．Experts suggest turning off your computers and smartphones 1hour or at least 30minutes before bed．
Take naps
If you aren't getting enough sleep at night，you're likely going to feel a strong desire to sleep in the afternoon．When this happens，you're better off taking a short nap than turning to caffeine or strong tea to keep you awake．A short nap will give you the rest you need to get through the rest of the afternoon，and you'll sleep much better in the evening．
21．According to the passage，we can learn that sleep efficiencyD．
A．is an advanced way to measure sleep quality
B．has close relationship with the state of health
C．is decided by the time you are lying in bed
D．can be greatly improved with certain measures taken
22．Which of the following may contribute to a better sleep in the evening？B
A．Taking a long afternoon nap．B．Sleeping for a while in the daytime．
C．Having a fixed go-to-bed time．D．Avoiding blue light in the evening．
23．What can we infer from the passage？D
A．Enough sleep will lead to a changeable wake-up time．
B．Blue light will affect the sleep due to its harm to the brains．
C．Waking up two hours before the body clocks means good sleep efficiency．
D.90% for sleep efficiency can possibly mean a quite good sleep state．
24．What will be the best title of the passage？B
A．Schedule your bedtime．B．Sleep well to be well．
C．Ensure long sleeping hours．D．Know more about your sleep．
