you laugh hard, tears will also come down from your eyes. But tears have a more important job than

阅读理解。     About ten men in every hundred have the trouble of color blindness in some way. Women are luckier,
only about one in two hundred is affected (感染) in this matter. Perhaps, after all, it is safer to be driven
by a woman.
    There are different kinds of color blindness. For example, a man cannot see deep red. He may think
that red, orange and yellow are all shades (影子)of green. Sometimes a person can"t tell the difference
between blue and green. Only a few unlucky men may see everything in shades of green-a strange world
indeed.
    Color blindness in human beings is a difficult thing to explain. In only one eye there are millions of very
small things called "cones (锥状细胞)". These help us to see in the bright light and to tell differences
between colors. There are also millions of "rods ( 杆状细胞)", but these are used for seeing when it is
nearly dark. They show us shapes but not colors.
    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 light will. Human beings 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. 1. "Color blindness" means "______" in Chinese. A. 盲目
B. 无色
C. 色盲
D. 讨厌颜色2. Some people say it"s safer to be driven by women because ______. A. women drive more carefully
B. women are better at driving than men
C. women can see things more clearly
D. there are fewer color-blind women3. With the help of the "cones", we can ______. A. tell different shapes
B. kill insects
C. see in the dark
D. tell orange from yellow4. We can attract and kill mosquitoes by using a ______ light. A. red
B. yellow
C. blue
D. green5. Which of the following sentences about color blindness is TRUE?A. None of men can see deep red.
B. Not all of men have the same problem in recognizing colors.
C. None of men can tell the difference between blue and green.
D. All of men see everything in shades of green.

阅读理解。 Our eating habits (习惯) are very important for good health and strong body. There are times when
most of us like eating sweets and ice cream better than meat and rice. Sweets and ice cream are not bad
for us if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite(食欲). So the doctors suggest us we should have our meal regularly.
In old England, the judges usually asked the prisoners to eat bread without water. If they couldn"t
swallow(吞)the bread, it meant that they weren"t telling the truth. Though this seems strange and foolish,
they thought it was an excellent way of finding out the truth. A man who is worrying about something has
difficulties in swallowing dry bread, because he loses his appetite. 1. Good eating habits make us ________. A. strong
B. happier
C. more beautiful 2. It is good for us to have sweets and ice cream every day ________. A. after a meal
B. before a meal
C. when we are hungry 3. It is good for us to have our meal every day ________. A. earlier
B. at the same time
C. at any time 4. The judges in old England thought if a man didn"t tell the truth, he could ________. A. drink milk or tea
B. eat a lot of dry bread
C. hardly (几乎不) eat dry bread 5. A person who feels ________ may not want to eat. A. happy
