题目内容

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 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 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 have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings 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 colors around us.

1.The passage is mainly about _____________.

A. color and its surprising effects.

B. women being luckier than men

C. danger caused by color blindness

D. color blindness

2.According to the passage, with the help of the “cones”, we can_______________.

A. tell different shapes

B. see in a weak light

C. kill mosquitoes

D. tell orange from yellow

3.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. Women are fonder of driving than men.

D. Women are weaker but quicker in thinking.

4.Which of the statements about the color- blind is true?

A. Not all of them have the same problem in recognizing color.

B. None of them can see deep red.

C. None of them can tell the difference between blue and green.

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

Students from Florida International University in Miami walked on water Thursday for a class assignment. To do it，they wore aquatic (水上的)shoes they designed and created.

Alex Quinones was the first to make it to the other side of a 175－foot lake on campus in record time—just over a minute. Quinones，who wore oversized boat－like shoes，also won last year and will receive $ 500.

Students had to wear the aquatic shoes and make it across the lake in order to earn an “A” on the assignment for Architecture Professor Jaime Canaves'Materials and Methods Construction Class.“It's traditional in a school of architecture to do boats out of cardboard for a boat race.

A total of 79 students competed in the race this year in 41 teams. Only 10 teams failed to cross the lake. Others who fell got back up and made it to the end. The race is open to all students and anyone in the community. The youngest person to ever participate was a 9－year－old girl who competed in place of her mother，while the oldest was a 67－year－old female.

A large crowd on campus joined Canaves as he cheered on the racers. He shouted encouraging words，but also laughed as some unsteadily made their way to the end.

“A part of this is for them to have more understanding of designing and make it work better，” he said. It is also a lesson in life for the students.

“Anything，including walking on water，is possible，if you do the research，test it and go through the design process seriously.
