About ten men in every hundred have the trouble of colour blindness in some way. Women are luckier, only about five in every hundred are affected in this matter. Perhaps, after all, it is safer to be driven by a woman.

Color blindness in human beings is a strange thing to say clearly. In only one eye there are millions of very small things called “cones”(圆锥细胞). These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”(棒), but these are used for seeing when it is nearly dark. They show us shapes but no colors. People suffer from colour blindness when there is something wrong with the cones.

Some insects have favourite 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 favourite 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 invisible colors around us.

Birth order-does it matter? Are you different because you are the first, second, or third child in your family-or maybe the last of nine?

A study found that first-borns have an average (平均) IQ that is three points higher than people who fall into a different place in the birth order, perhaps because first-borns often help younger brothers and sisters, which improves their own skills. In 2007, an international organization of CEOS found that 43% of CEOS are first-borns, 33% are middle children, and 23% are last-borns. First-borns are more likely (可能) to be doctors and astronauts and get higher pay.

If first-borns are more successful, last-borns are generally more agreeable. They are also more likely to be funny, possibly to get attention from all the bigger people at the dinner table. Mark Twain and Stephen Colbert were both the youngest in large families, and Jim Carrey was the youngest of four. According to a 2007 Time magazine, article, “The Power of Birth Order,” last-borns are more likely to be artists and successful businessmen.

Then there are the middle children: we have not ignored (忽视) them! Many middle children are short of one-on-one time with their parents. They often feel short-changed: the oldest gets more rights, and the youngest is “spoiled (宠坏的)”. Though they may be ignored, middle children are more likely to grow into easygoing adults.

Many factors (因素) make us who we are, but if the research is correct, birth order may be one of the most important factors.

In 1901,an Austrian scientist discovered that there are four types of blood.He named t    60     A, B, AB and O.People have one of these f    61     types.Blood type O is the most common around the world.Blood type A is the second most common,and blood type AB is the l    62     common.

In 1927,a Japanese doctor f    63     that people with different blood types have different personalities (性格), too.He said that people with type A blood are usually calm and serious; people with type B blood are cheerful and outgoing; people with type O blood are generous and honest; w    64     those with type AB blood are often caring and talented.
