4．Hawking has left much for Chinese to think about．  British physicist Stephen Hawking，possibly the world's most famous scientist after Albert Einstein，gave lectures in Zhejiang and Beijing in August．
An illness left him unable to move any part of his body except for three fingers． But his continuing efforts in the field of science have made many young people take him as their idol（偶像）．His books，Such as A Brief History of  Time（《时间简史》），become best sellers in Chinese bookstores．"Hawking helps people expand their-horizons and become interested in science，"said Pan Yunhe，president of Zhejiang University．
Indeed，experts don't think it likely that Hawking's lectures and profound（深奥的） ideas will be easily understood by the average person．  But he has certainly sowed the seeds of science among many young people．
And the"Hawking fever"caused by his visit has made people ask，"How can China produce more top scientists like Hawking？"
"Nurturing（培养）top scientists will take as much work to change society as to educate the scientists themselves，"said Zhang Fan．Zhang has studied in the UK since 1999and will be a sophomore（大学二年级学生）at Trinity College in October，2002．
In Britain，Zhang said，teachers encourage students to have a general understanding of the subjects they are interested in．  And they also encourage students to develop new ideas，which helps them to nurture their creativity．
In China，the Ministry of Education（教育部）has encouraged schools to provide quality education to tap（开发）student potential（潜力）．
"I hope teachers will pay more attention to helping us use our imaginations（想象力） and solve problems on our own，"said Lu Jie，a 9th grader of Sanfan Middle School in Beijing．

1．Housework is a frequent source of conflict between lazy husbands and their hard-working wives，but women have been warned not to expect men to pull their weight any time soon．
A study from Oxford University has found that men are unlikely to be doing an equal share of housework before 2050．Mothers，the researchers warned，will continue to shoulder the burden of childcare and housework for the next four decades，largely because housework such as cleaning and cooking is still regarded as"women's work"．
The gap between the amount of time men and women spend on housework has narrowed slowly over the past 40 years．But it will take another four decades before true housework equality is achieved，the study concluded．
The research found that in the Nordic countries，the burden of housework is shared more equally between men and women．In the UK，women spend an average of four hours and forty minutes each day on housework，compared with two hours and twenty-eight minutes for men．This is an improvement from the 1960s，when British women typically spent six hours a day on housework，while men spent just 90minutes every day．
But progress towards housework equality appears to be slowing in some countries．Dr Oriel Sullivan，a research reader from Oxford's Department of Sociology，said，"we've looked at what is affecting the equality in the home，and we have found that certain tasks seem to be given according to whether they are viewed as‘men's work'or‘women's work'．"
Dr．Sullivan said cultural attitudes taught at school may be responsible for the views of housework．"At school it is much easier for a girl to be a tomboy，but it is much more difficult for a boy to enjoy baking and dancing，"she said．

25．What does the underlined part"pull their weight"in Paragraph 1 probably refer to？C
A．Lose weight．
B．Earn money．
C．Do equal housework．
D．Be lazy．
26．Why will women continue to do more housework before 2050？D
A．Men are too busy to help．
B．They would like to do so．
C．They can do better in housework．
D．Housework will still be considered"women's work"．
27．From Paragraph 4 we know that in the UKB．
A．men now spend just 90 minutes a day on housework on average
B．women now spend less time on housework than before
C．housework is shared equally between men and women
D．women now are too busy with their work to do housework
28．In Dr．Sullivan's opinion，what is to blame for the housework inequality？A
A．Cultural attitudes towards housework．
B．Policies made by the government．
C．The time spent on work．
D．The type of housework．

8．Overhead bridges are found in many parts of big cities，especially in places （46）where traffic is very heavy and crossing the road is dangerous．The purpose of these bridges （47）is（be） to enable pedestrians to cross roads （48）safely（safe）．Overhead bridges are used in very much the （49）sameway as Zebra crossings．They are more efficient although （50）less（little） convenient because people have to climb up a long flight of steps．This is （5）inconvenient（convenient） especially to older people．When pedestrians use an overhead bridge，they do not hold up traffic．However，when they cross a busy road using a zebra crossing，traffic is held up．This is why the government has built many overhead bridges （52）to help（help） pedestrians and to keep traffic moving at the same time．For their own safety，pedestrians should be encouraged to use them instead of （53）risking （risk） their lives by dashing across the road．Old people，however，may find it a little difficult climbing up and down the steps，but it is still much safer than walking across the road with all the danger of moving traffic．Overhead bridges serve a very useful purpose．Pedestrians，both old and young，should make （54）it a habit to use them．This will prevent unnecessary accidents and （55）loss（lose） of life．

6．Scientists announced that they had found the gravitational waves（引力波）that confirmed a prediction made by Albert Einstein a century ago．The discovery，made with the Laser Interferometer Gravitational-Wave Observatory，known as LIGO，is the milestone（里程碑）in a decades-long search for signs of this phenomenon．"The discovery will open a new window onto the universe，"said David Reitze，executive director of LIGO．
Since humans first watched skyward，we have relied on light of all wavelengths to describe the universe．The light that could be seen first showed the starry heavens，while infrared（红外线的）waves allowed us to see older and more distant stars．
But now，researchers will be able to sense the universe in a whole new way：with their"ears"．"We can hear gravitational waves．We can hear the universe，"Gabriela Gonzalez，LIGO's spokeswoman at Louisiana State University，said．"That's one of the beautiful things about this：We are not only going to be seeing the universe，we are going to be listening to it．"
Gravitational waves，which Einstein predicted as part of his general theory of relativity，occur as objects accelerate or decelerate through space，much the way a boat moving on a lake sends waves across the water's surface．But they're so tiny that until now it's been nearly impossible to find them，even those caused by something as large as a planet moving around the sun．
To pick up this signal，scientists have to look for violent events in the universe．This particular signal appears to have been caused by a collision．That occurred about 1.3 billion years ago between two black holes，holding 29 and 36 solar masses（太阳质量）．
Fiona Harrison，chair of Caltesh's division of physics，mathematics and astronomy，guessed that hundreds of new events would be found over the next few years，allowing scientists to perform a range of different types of studies．"There are probably many events we haven't dreamed of and this is just the beginning，"she said．

29．Why did Gabriela Gonzalez think LIGO's discovery important？D
A．It confirmed Einstein's scientific prediction．
B．It allowed scientists to see more distant stars．
C．It changed traditional ideas about the universe．
D．It offered different way to study the universe．
30．It's hard to find gravitational waves because theyB．
A．are too far to be felt
B．are too weak to be observed
C．are disturbed bu other planets
D．disappear soon after they happen
31．Which of the following would scientists consider to be a violent event？C
A．Hearing the universe．
B．Searching for infrared waves．
C．A collision between black waves．
D．A planet moving around the sun．
32．It can be concluded thatB．
A．gravitational waves also exist in objects at rest
B．there's a long way to go in studying the universe．
C．gravitational waves show the beginning of the universe．
D．scientists began studying gravitational waves in recent years．
