[单项选择]
British men are couch potatoes who spend nearly half their free-time watching TV, an EU survey has revealed. They watch more TV than women, do less housework, less charity work and less childcare -- but spend more time shopping, the poll suggests. Analysts from Eurostat, the EU’s statistical office, interviewed working men and women in 10 countries.
Britain, where men devoted 49% of their free-time to the box, came a narrow second to the Hungarians with 51%. German and Norwegian men watched the least TV -- just over one third of their spare time. The statisticians took the average of the figures for the whole year including holidays and weekends. They broke down the "average day" into five categories -- free-time, sleep, meals and personal care, travel, domestic chores and work/study.
It shows that British men have four hours and 41 minutes free time each day -- 20 minutes more than women. But women spend nearly double the amount of time on domesti

Depression
Although the stigma（耻辱）once associated with mental illness has gradually gone away in recent years,most of the Americans who have clinical depression still don't get treated for it partly because many are too embarrassed to go to a psychologist. In fact,the majority of depressed people who seek professional help turn first not to a psychologist but to their primary care physician.
But do regular doctors really know how to identify depression?A large new scientific review suggests they don't. In a review of 41 previous studies,the authors found that general practitioners make frequent mistakes,missing true cases of depression about half the time and incorrectly diagnosing it in 19%of healthy people.
Alex Mitchell,Amol Vaze and Sanjay Rao of Leicester General Hospital in the U.K. estimate that about 1 in 5 people in developed nations will experience depression in their lifetime.That means that among a general patient population of 100,about 20 will develop the condition,but the typical doctor will find it in only 10 of those who have it. And among the 80 healthy people,the doctor will incorrectly identify depression in 15.
This is significant because depression can make the patient and his or her family weak.Depression also carries an enormous social burden,leading to missed work days,loss of productivity and increases in health-care spending. Further,those misdiagnosed with depression may end up being prescribed medicine that not only costs a lot but can have serious side effects.
The various studies that Mitchell,Vaze and Rao reviewed used different methods to verify whether doctors had missed depression in their patients.Virtually all the studies pointed to the same conclusion:general physicians aren't very good at recognizing the most common mental illness in the world.
Why?One reason is that the typical doctor visit is quite short,usually no longer than 15 minutes.It's hard for patients to open up about their symptoms during that brief period.Doctors should spend more time or schedule follow-up appointments with patients they suspect have depression, which would dramatically increase the rate of accurate diagnoses.
Those who"will develop the condition"(Line 3,Para. 3)refer to________.
A.patients who will be misdiagnosed as depression
B.patients who will survive depression
C.patients who will suffer from depression
D.patients who receive correct diagnose

In the past few decades, remarkable findings have been made in ethology, the study of animal social behavior. Earlier scientists had (1) that nonhuman social life was almost totally instinctive or fixed by genetics. Much more careful observation has shown that (2) variation occurs among the social ties of most species, showing that learning is a part of social life. That is, the (3) are not solely fixed by the genes. (4) , the learning that occurs is often at an early age in a process that is called imprinting. Imprinting is clearly (5) instinctive, but it is not quite like the learning of humans; it is something in between the two. An illustration best (6) the nature of imprinting. Once, biologists thought that ducklings followed the mother duck because of instincts.
