¡¾ÌâÄ¿¡¿Doctors sometimes use 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 disorder. 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 that 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 night-time darkness, those getting dim light at night lost their strong preference for sweet drinks. ¡°A sign that 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¡±, 10 times as long as the mice that had experienced normal night-time darkness. All symptoms of depression disappeared within two weeks of the mice returning to a normal light-dark cycle, the researchers report. The scientists could also quash the behavioral symptoms by injecting 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 night-time light and mood disorders are important but can not easily detect molecular underpinnings(·Ö×Ó»ù´¡) 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¡±.
¡¾1¡¿After being exposed to continuous night-time light, the mice __________.
A. changed their preferences
B. escaped from the water more eagerly
C. remained active as before
D. showed less interest in their favorites
¡¾2¡¿What does the underlined word ¡°quash¡± in paragraph 4 probably mean?
A. study B. predict

¡¾3¡¿We can learn from the last paragraph that _______________.
A. light at night may have practical value
B. the biological clock is beneficial to humans
C. human mood disorders cannot be healed easily
D. human studies are more important than animal studies
¡¾4¡¿What is the main idea of the passage?
A. Night-time light may cause depression.
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 light.

¡¾ÌâÄ¿¡¿Migrants to the UK are to be quizzed about their English skills before being able to claim income-related benefits, the government has announced.
In a move to "protect the integrity£¨ÍêÕûÐÔ£©of the benefits system", people will also be asked what efforts they have made to find work before coming to Britain. Work and Pensions Secretary Duncan Smith said people should not be able to "take advantage" of British benefits. Job centres in England, Scotland and Wales will use the "more mighty" test. The Department for Work and Pensions (DWP) said the test would ensure "only migrants who have a legal right to be in Britain and plan to contribute to this country can make a claim for benefits".
"For the first time, migrants will be quizzed about what efforts they have made to find work before coming to the UK and whether their English language skills will be a barrier to them finding employment," the DWP said in a statement.
Income-related benefits include council tax benefit, housing benefit, income-based jobseeker's allowance and pension credit.
Mr. Duncan Smith said British people were "rightly concerned" that migrants should contribute to the economy and should not be "drawn here by the attractiveness of our benefits system".
"It is vitally important that we have strict rules in place to protect the integrity of our benefits system," he said. He said the new test would help create a fair system which provided for "genuine" workers and jobseekers but "does not allow people to come to our country and take advantage".
To claim the benefits, migrants will have to pass a "habitual residence test" including more than 100 extra questions compared to now. This will be overseen by an "intelligent IT system" which will ensure questions are "tailored to each individual claimant".
Migrants will be allowed to claim benefits if they can prove they are legally allowed to be in Britain and are "habitually resident" of the country. As part of this they might be questioned about what measures they have taken to "establish" themselves in Britain and what ties they still have abroad.
"They will also have to provide more evidence that they are doing everything they can to find a job," the DWP said.
¡¾1¡¿What does the British government use the test for?
A. promoting the English skills of migrants.
B. making efforts to help migrants find work.
C. protecting the rights of migrants.
D. ensuring the British benefit claimed legally by migrants .
¡¾2¡¿What do we know about the test?
A. All British residents must be quizzed about their English skills.
B. The test will ask migrants whether they are willing to work in Britain.
C. The test is an act to protect British benefits system.
D. The test will help the government dismiss jobseekers.
¡¾3¡¿What does the underlined word ¡°claimant ¡°(in para.7) probably mean in the text?
A. a person who applies B. a person who is badly off
C. a person who migrates D. a person who is quizzed
¡¾4¡¿What does the passage mainly want to inform us?
A. All migrants can claim benefits from the UK.
B. Income-related benefits can be a great help to migrants.
C. All migrants come to the UK only to claim benefits.
D. Migrants are to pass a test to get the benefits from the UK.
