4．Before us lies the biggest room，________with things like guns，dolls and old clothes．（　　）

	A．	filling		B．	filled
	C．	being filled		D．	having been filled

3．I don't think _______ of his parents is at home．They usually go out for a walk at the moment．（　　）

2．The book is of great value．______ can be enjoyed unless you digest it，though．（　　）

1．I don't ever want to talk about being a woman scientist again．There was a time in my life when people asked constantly for stories about what it's like to work in a field dominated （主导） by men．I was never very good at telling those stories because truthfully I never found them interesting．What I do find interesting is the origin of the universe，the shape of space-time and the nature of black holes．
At 19，when I began studying astrophysics （天体物理学），it did not bother me in the least to be the only woman in the classroom．But while earning my Ph．D．at MIT and then as post-doctor doing space research，the issue started to bother me．My every achievement-jobs，research papers，awards-was viewed through the lens of gender （性别） politics．So were my failures．Sometimes，when I was pushed into an argument on left brain versus （相对于） right brain，or nature versus nurture （培育），I would immediately fight fiercely on my behalf and all womankind．
Then one day a few years ago，out of my mouth came a sentence that would from then on become my reply to any and all attacks：I don't talk about that anymore．It took me 10years to get back the confidence I had at 19and to realize that I didn't want to deal with gender issues．Why should curing sexism be yet another terrible burden on every female scientist？After all，I don't study sociology or political theory．
Today I research and teach at Barnard，a women's college in New York City．Recently，someone asked me how many of the 45students in my class were women．You cannot imagine my satisfaction at being able to answer：45．I know some of my students worry how they will manage their scientific research and a desire for children．And I don't dismiss those concerns．Still，I don't tell them"war"stories．Instead，I have let them see their physics professor heavily pregnant （怀孕） doing physics experiments．And in return they have given me the image （形象） of 45women driven by a love of science．And that's a sight worth talking about．

D．People's traditional attitude towards female scientists．
59．Why does the author feel great satisfaction when talking about her class？D
A．Female students no longer have to worry about gender issues．
B．Her students'performance has brought back her confidence．
C．Her female students can do just as well as male students．
D．More female students are studying science than before．
60．What does the image the author presents to her students suggest？A
A．Women can balance a career in science and having a family．
B．Women students needn't have the concerns of her generation．
C．Women now have fewer gendre problems about science career．
D．Women have more difficulties on their way to academic success．

20．A new study has found that it may be possible to train people to be more intelligent （聪明的），increasing the brainpower they had at birth．
Until now，it has been widely supposed that the kind of mental ability that allows us to solve new problems without having any relevant （相关的） former experience-what psychologists （心理学家） call fluid intelligence-is innate and cannot be taught （though people can raise their grades on tests of it by practicing）．
But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works．
The key，researchers found，was carefully structured training in working memory-the kind that allows memorization of a telephone number just long enough to dial it．This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence．
First they measured fluid intelligence of volunteers using standard tests．Then they trained each in a complicated memory task-the child's card game，in which they had to recall a card they saw and heard．During the course，they needed to ignore irrelevant items，monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time．
The four groups experienced a half-hour of training daily for 8，12，17and 19days，separately．To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training．
The results，published Monday in The Proceedings of the National Academy of Sciences，were striking．Improvement in the trained groups was a lot greater．Moreover，the longer they trained，the higher their scores were．All performers，from the weakest to the strongest，showed great improvement．
"Our results show you can increase your intelligence with proper training．"said Dr Jaeggi，a co-author of the paper．"No one knows how long the gains will last after training stops，"he added，"and the experiment's design did not allow the researchers to determine whether more training would continue to produce further gains．"

53．The researchers thought the key to improving the intelligence wasB．
A．memorizing telephone numbers
B．improving working memory
C．training in attention
D．recalling a card
54．Which of the following training ways help increase intelligence？D
a．ignoring irrelevant items
b．monitoring ongoing performance
c．making connections
d．working in groups
A．a，b，d． B．b，c，d． C．a，c，d． D．a，b，c．
55．When the experiment was conducted，the researchersC．
A．trained the four groups for the same period of time
B．trained the four groups at different time of the day
C．compared the four groups with control groups
D．trained the four groups together
56．By writing the article，the writer wants toA．
A．inform the readers of a new study
B．call on people to be trained to increase intelligence
C．tell people the improved intelligence will last forever
D．say the more one is trained，the more one's born intelligence improves．
