3．About ten men in every hundred suffer from color blindness in some way．Women are luckier； only about one in two hundred is affected （影响） in this matter．Perhaps，after all，it is safer to be driven by a woman!
There are different forms of color blindness．In some cases a man may not be able to see deep red．He may think that red，orange and yellow are all shadows（阴影） of green．Sometimes a person cannot tell the difference between blue and green．In few cases an unlucky man may see everything in shades of green-a strange world indeed．
Color blindness in human beings is a strange thing to explain．In a single eye there are millions of very small things called"cones"．These help us to see in a bright light and to tell difference between colors．There are also millions of"rods"，but these are used for seeing when it is near dark．They show us shape but no color．
Some insects （昆虫） have favorite colors．Mosquitoes （蚊子） prefer blue to yellow．A red light will not attract insects，but a blue lamp will．In a similar way human also have favorite colors．Yet we are lucky．With the help of the cones in our eyes we can see many beautiful colors by day，and with the help of the rods we can see shapes at night．One day we may even learn more about the hidden colors around us．

24．The passage is mainly aboutA．

20．July 21^st． 2007 was a typical English summer's day-it rained for 24 hours!As usual，I rushed home from work at midday to check on the house．Nothing was amiss．By the time I left work at 5pm．However，the road into our village was flooded．Our house had never been flooded but，as I opened the front door．a wave of waters greeted me．Thank God the kids weren't with me，because the house was 5 feet deep in water．We lost everything downstairs．And the plaster had to be torn off the wall's ceilings pulled down．
At first we tried to push on through．We didn't want to move the children out of home．so we camped upstairs．We put a sheet of plastic across the floor to protect us from the damp．But after three months，we felt very sick，so we move to a wooden house in a park．The house was small．but at first we were all just delighted to be in a new place．Unfortunately，things took longer than expected and we were there for 10 months．The life there was inconvenient．What surprised me most was how much I missed being part of a community（社区）．We had lived in a friendly village with good neighbors，and I'd never thought how much I，I'd miss that．
Although our situation was very bad，it's difficult to feel too sorry for yourself when you look at what's happening elsewhere．I watched a news report about floods in Northern India and thought．"We didn't have a straw hut（茅草房）that was for Christmas．But I can't wait-I'm going to throw a party for our friends in the village to say thanks for their support．This year，I won't need any gifts-living away from home for months has made me realize how little we actually need or miss all our possessions．Although we are replacing things，there's really no rush-we have our home back．and that's the main thing．

4．As any plane passenger will confirm，a crying baby is almost impossible to ignore，no matter how hard you try．Now scientists believe they may have worked out why．A baby's cry pulls at the heartstrings（扣人心弦） in a way while other cries don't，researchers found．
Researchers found that a baby's cry can trigger  unique emotional responses in the brain，making it impossible for us to ignore them---whether we are parents or not．Other types of cries，including calls of animals in great pain，fail to get the same response---suggesting the brain is programmed to respond specifically to a baby's cry．
A team of Oxford University scientists scanned the brains of 28men and women as they listened to a variety of calls and cries．After 100milliseconds two parts of the brain that respond to emotion lit up．Their response to a baby's cry was particularly strong．The response was seen in both men and women-even if they had no children．
Researcher Dr Christine Parsons said，"You might read that men should just notice a baby and step over it and not see it，but it's not true．There is a special processing in men and women，which makes sense from an evolutionary（演变的） view that both men and women would be responding to these cries．"The study was in people who were not parents，yet they are all responding at 100ms to these particular cries，so this might be a fundamental response present in all of us regardless of parental status．
Researcher Katie Young said it may take a bit longer for someone to recognize their own child's cries because they need to do more"fine-grained analysis"．The team had previously found that our reactions speed up when we hear a baby crying．Adults performed better on computer games when they heard the sound of a baby crying than after they heard recordings of adults crying．

A．Almost everyone makes certain response to a baby's cries．
B．A crying baby makes no sense to people without children．
C．Men pay less attention to a crying baby than women．
D．Parents can hardly recognize their own babies'cry．
8．Computer games are mentioned in the text to showB．
