They also did more household work and participated in more of such organized activities as soccer and ballet. Involvement in sports, in particular, rose almost 50% from 1981 to 1997: boys now spend an average of four hours a week playing sports; girls log half that time.

[单项选择]Passage Three

The average number of authors on scientific papers is sky-rocketing. That’s partly because labs are bigger, problems are more complicated, and more different subspecialties are needed. But it’s also because U.S. government agencies have started to promote "team science". As physics developed in the post-World War II era, federal funds built expensive national facilities, and these served as surfaces on which collaborations could crystallize naturally.
Yet multiple authorship—however good it may be in other ways--presents problems for journals and for the institutions in which these authors work. For the journals, long lists of authors are hard to deal with in themselves. But those long lists give rise to more serious questions when something goes wrong with the paper. If there is research misconduct, how should the liability b
A. are getting more complicated
B. are dealing with bigger problems
C. are more of a product of team work
D. are focusing more on natural than on social sciences

[单项选择]Passage Four

Today the average worker is paid less than $ 4 an hour in Portugal and $ 9 an hour in Spain, compared with $13 in Germany and almost $16 in Denmark. Taking accounts of non-wage costs, such as employer’s social-security contributions, the gap is wider still: from $ 6 in Portugal to $ 24 in Germany. With the EC’s single market knocking down barriers in intra-European trade, no wonder German companies now seem keener on sunnier climes. But how long will southern Europe’s cost advantage last
Conventional wisdom argues that greater economic integration within the single market, and later under a single currency, will cause wages to converge. Increased labor mobility, for example, should allow worker to move from low-wage to high-wage economics. Increased trade and cross-border investment should also push labor costs closer.
The e
A. decreased trade and cross-border investment push the labor costs lower
B. labor mobility and the easiness of communicating allow worker to migrate
C. the pace of convergence is seemingly stepping up at a higher rate
D. the southern Europe’s cost advantage will last for a while
