There are different forms of color blindness. In some cases a man can not see deep red. He may think that red, orange and yellow are all shades 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 nearly dark. They show us shape 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 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 (看不见的) colors around.

Music education has received a lot of attention. Learning to play an instrument can help children improve math, science, and language skills. One study in Canada tracked children"s IQ scores for nine months, discovering that children who studied music had the biggest test score improvements. The secret may lie in the way reading music and playing notes uses several areas of the brain, increasing our ability to learn school subjects. For example, reading notes improves spatial (空间的) reasoning skills, which are helpful in solving math problems like fractions(分数).
Music is also used for medical purposes, such as the treatment of diseases which affect memory. The secret lies in the way the brain processes music. One area near the forehead, the medial prefrontal cortex, connects music with memories stored in two other areas: the amygdale and hippocampus. That"s why an old song can remind you of something that happened years ago. For patients suffering from diseases like Alzheimer"s, listening to music can help unlock buried memories by strengthening musical pathways to memories.
With the evidence of music"s benefits pouring in, it"s no wonder some countries make music study a part of their education systems. People are recognizing that more than just a form of entertainment, music is also great for the brain.
小题1:Scientists are studying music because _______.
A.music can be used for medical treatments |
B.music plays a very important role in our lives |
C.our brains can possess music in different ways |
D.music education has received a lot of attention |
A.Those who already had high IQs. |
B.Those who had always played music. |
C.Those who could not play any instrument. |
D.Those who studied music for a period of time. |
A.Spatial reasoning. | B.Alzheimer"s. |
C.The amygdale and hippocampus. | D.The medial prefrontal cortex. |
A.Music and health | B.Music and the mind |
C.Music and education | D.Music and instruments |
A learning disability is not a problem with IQ or motivation (动机). Kids with learning disabilities aren’t lazy or slow. In fact, most are just as smart as everyone else. Their brains are just wired (装电线) differently. Simply put, children and adults with learning disabilities see, hear, and understand things differently. This difference affects how they receive and process (处理) information. This can lead to trouble in learning new information and skills, and putting them to use.
It can be tough to face the possibility that your child has a learning disorder. No parents want to see their children suffer. You may wonder what it could mean for your child’s future, or worry about how your kid will make it through school. But the important thing to remember is that most kids with learning disabilities are just as smart as everyone else. They just need to be taught in ways that suit their unique learning styles.
It’s not always easy to tell whether a child has learning disabilities, for learning disabilities look very different from one child to another. One child may struggle with reading and spelling, while another loves books but can’t understand math. Still another child may have difficulty understanding what others are saying or communicating loud. However, some warning signs are more common than others at different ages. If you’re aware of what they are, you’ll be able to catch a learning disorder early and quickly and take steps to help your child as quickly as possible.
小题1:From the passage, we can infer that_______.
A.students with learning disabilities look quite different from normal students |
B.students with learning disabilities can’t do well in their studies |
C.only few students with learning disabilities are as clever as normal students |
D.it is quite possible for a students with learning disabilities to succeed in their studies |
A.Learning about learning disabilities. |
B.How to prevent learning disabilities. |
C.Ways to identify learning disabilities. |
D.Different learning disabilities. |
A.Some ways which help parents teach their children with learning disabilities better. |
B.Some suggestions on how to get along with their children with learning disabilities. |
C.Some parents may have difficulties in helping their children with learning disabilities. |
D.Some warning signs which show that a child may have learning disabilities. |
One day, I was riding with a friend when we rolled to a stop at the traffic light. As we waited for the light to turn green, a man walked across the crosswalk. He looked very together, so I called out, “Hey, you look sharp today!” Pointing towards a building, he said, “Thanks, but I was sharper there.” His comment puzzled me. But before I could ask about it, the light turned green, and we drove on. I asked my friend what he meant. My friend informed me that we were at the corner of a radio station and the man was the voice on the radio. Then I understood. But no matter who he was the biggest thing for me was that he was smiling when he accepted my compliment (赞扬).
Later that day, there was a woman standing on the corner where we were turning, and I yelled (大喊) the compliment again, “You look nice!” She was just taking a sip of a bottle of water and started to laugh. I felt good to get a laugh.
Another day, while seated in a restaurant, there was a lady sitting near me. I really did not care for her skirt, but she did look nice in it, so I told her, “You look nice today.” She looked at me and rolled her eyes a little. Well, her friend sitting next to her told her, “He just gave you a compliment. Say thank you.” I don’t remember whether she said “thank you” or not, but what I did notice was that her friend was smiling at my “You look nice today” compliment.

In experiments, babies of 6 to 12 months old were placed in a room with many choices of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating habits, but over a period of time they managed to choose a well-balanced diet.
So in choosing food, rats and babies do seem to know what"s best for them. Clearly, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by old habits. Some people eat foxes, dogs and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seem to be greatly influenced by what is going around them.
小题1: In the experiment on rats, a sweet smell was added to the rats’ drinking water to ________ .
A.encourage rats to drink vitamins-enriched water |
B.test whether rats know which drink is good for them |
C.find out rats’ preference in flavor(口味) |
D.show the vitamins are tasteless |
A.both have the wisdom to choose a balanced diet |
B.both prefer flavored food and drink |
C.both have the same eating habits |
D.both develop a taste for the same kinds of food |
A.given many choices of drinks |
B.placed and fed in a hospital |
C.given all kinds of baby food |
D.trained to select a balanced diet |
A.they know better than babies what kinds of food are good for their health |
B.they usually cannot say no to all kinds of delicious foods |
C.their eating habits have much to do with the social and cultural customs |
D.they have more choices of food than babies in eating patterns |
The information Highway is the road that links computer users to a large number of on-line services; the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowed road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.
