About ten men in every hundred suffer from color blindness in some way．Women are luckier．Only about one in two hundred is affected in this matter．So some people say it is safer to be driven by women．

There are different forms of color blindness．]n some cases a man may not be able to see deep red．He may think that red，orange and yellow arc all shades（色調(diào)）of green．Sometimes a person cannot tell the difference between blue and green．In rare cases an unlucky man may see everything in shades of green--a strange world indeed．

Color blindness in humans is a strange thing to explain．In our eyes there are millions of very small things called “cones”．These help us to see in a bright light and to tell differences between colors．There are also millions of “rods”，but these are used for seeing when it is nearly dark．They show us shapes but no color．

Some insects have favorite colors．Mosquitoes（蚊子）like blue but do not like yellow．A red light will not attract insects，but a blue lamp will．In a similar way humans also have favorite colors．Yet we are lucky．With the aid of the cones in our eyes We can see many beautiful colors by day，and with the aid of the rods we can see shapes at night．One day we may even learn more about the invisible（看不見的）colors around us．

1．With the help of the cones，we can _________．

A．see in a weak light                                   B．tell different shapes

C．kill mosquitoes                                           D．tell orange from yellow

2．Why do some people say it is safer to be driven by women?

A．Women are more careful．

B．There are fewer color blind women．

C．All of them see everything in shades of green．

D．None of them has trouble in recognizing（識別）colors．

3．This passage is mainly about _________．

A．color and its surprising effects                         B．danger caused by color blindness

C．color blindness                                          D．the invisible colors around us

Do you think there is too much noise in our city? If you live near an airport，you will be unhappy because of a plane often make a loud noise．The sound of planes or heavy vehicles is likely to cause deafness if heard continuously（不斷地）．

However, most people in our city do not seem to mind noise. They like to enjoy music when they are doing uninteresting jobs．It is a new danger because pop music，when played through powerful amplifiers（放大器），can reach 120 decibels（120分貝的）at a distance of five feet．A continuous noise of over 85 decibels can cause deafness．It was discovered that many young people in America could hear no better than 65-year-old people．

In the past we used to think that only workers in every noisy places would become deaf．For example，when newspapers and books are being printed，the noise level is over 85 decibels，and some of the workers become deaf．Today，however，scientists believe that 10 percent of the workers in Britain are being deafened by the noise．

Sometimes noise of less than 85 decibels can make some people tired and stressed．We all know that too much noise makes life difficult and unpleasant．It can do great harm to people's health and prevent people from working well．Workers in noisy offices are not as efficient（效率高的）as those in quiet offices．Noise makes people less efficient．Can anything be done to reduce or control noise?

In Britain the government has made several laws to reduce noise．Though the government has spent a lot of money in making airports and main roads quieter，many people think that there are still not enough laws．For example，there are no laws to control the noise of machines．In Japan，America and Norway there are such laws．As a result，workers can be given compensation（賠償）if they become deaf．

1．Some workers become deaf because of ________．

A．hard work                               B．a continuous noise of over 85 decibels

C．powerful amplifiers                       D．uninteresting jobs

2．Noise below the level of 85 decibels ________．

A．can affect some people's moods                     B．cannot do any harm

C．can cause sudden deafness                 D．can make office workers efficient

3．In Britain there are laws to ________．

A．stop workers from becoming deaf                   B．control the noise of machines

C．keep down noise                        D．help deaf workers in need

4．Who can be given compensation if they become deaf?

A．American workers．

B．British workers．

C．Both American workers and British workers．

D．None of the above answers．

Mary picked up a pencil and a piece of paper，saying，“Now，you want to earn money for the autumn camping trip，right?” Tom，her brother，nodded．He wasn’t able to go last year because he hadn’t earned enough money during the summer．This year he came up with a plan．

“OK，” said Mary，“The first thing you need to do is to figure out（計算）how much you have now．’’

“I have $20.00 in the bank，and $7.25 in my room，” explained Tom．

“Well，the pet shop wilt give me all the feathers the birds lose．I'll have to buy the beads（小珠子）and string，” said Tom．

Mary wrote on the piece of paper：

“Hmm，” Tom looked thoughtful and said，“There's a shop in town that sells almost the same kind of necklace for $ 7.50．If I charge（要價）$ 6.00，people will think that's a bargain．”

“OK．If you sell each necklace for $ 6.00，you'll make a good profit（利潤）on each then，” said Mary．
