It takes years of school to develop math skills, but learning about numbers starts earlier than you might think. Now according to a new study, at three months, babies have already started acquiring a concept (概念) of “how much”.
Previous research had suggested that very young babies can tell when the number of objects (物体) in a group has changed. But the babies in these studies were simply reacting generally to the fact that something had changed, they suspected.
Researchers of Harvard University studied 36 babies, all three months old. During the tests, each baby wore a hat with sensors (传感器). The babies watched a series of images on a computer screen. They showed the same object, such as a cartoon character. For a while, the number of the objects in the pictures didn’t change. Then the images began to display a different object, or a different number of one of the objects the babies had previously looked at. As soon as something changed, the babies’ brains responded with a specific pattern of electrical signals, which would be recorded by sensors.
By analyzing these signals, the researchers discovered that one part of the brain (near the top on the left side) responded when the object in the image changed. A different part of the brain (lower and on the right side) responded when the number of objects in the image changed. This was not the area of the brain that is involved in attention. That suggests that the babies’ brains are doing more than just reacting to a change in what they’re seeing – they actually seem to be able to tell number changes from other types of changes.
Numbers and amounts are important concepts in our lives. Even though babies are years away from adding, subtracting (减), multiplying, and dividing, their brains seem to be preparing for a time when they finally will.
1.Why were hats with sensors used in the study?
A.To record the images on the computer screen. |
B.To remind babies of the changes of numbers. |
C.To record the electrical activity of each baby’s brain. |
D.To help babies concentrate on the computer screen. |
2.What does the underlined word “They” in the third paragraph refer to?
A.Babies involved in the study. |

It is common to consider learning as something that takes place in school, but much of human learning occurs outside the classroom, even from birth and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to use toys, food, and other objects. They use all of their senses to learn about the sights,sounds,tastes, and smells in their environments. They learn how to communicate with their parents, grandparents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics, They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for communicating with other children. After they finish school, people must learn to deal with the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human-service workers need to understand how certain experiences change people’s behaviors. Employers, politicians, and advertisers make use of the principles of learning to affect the behavior of workers, voters, and consumers.
Learning is closely related to memory, which is the storage of information in the brain. Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place and how the brain later outputs knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person’s experiences.

One of the most important things in being a good neighbor is to respect尊敬 a person’s privacy(隐私).When someone new moves into the neighborhood it is a good idea to watch them to see how friendly you should be. If you go rushing over as soon as they move in they may think you are going to be one of those neighbors that come over at all times of the day,not respecting their privacy.
It is a good idea always to be friendly to everyone in the neighborhood. This can not only put you on good terms with them,but will also be a form of protection for your family and home. If you wave as they drive by or offer a friendly hello while they are out in their yard this shows that you respect them. If you are friendly to them they are much more likely可能的 to watch out for any wrong doings going on around your home while you are out and let you know if anything happens.
Another way of being a good neighbor is to be helpful in times of need. If you see that they are in need of a helping hand doing something or in times of a disaster(灾难),it is good to offer your help. Even though you have never really talked to the people down the street,they are willing愿意的 to take the time to help out a neighbor in need.
In conclusion,if you respect a person’s privacy,treat them kindly and be helpful when you see they are in need,you will be a great neighbor and anyone would be happy to have you next door!

Being a good friend isn’t always easy, but taking the time to develop a lasting friendship is worth the effort. As the years pass, you will realize that each friendship you keep is priceless. 1.To be a good friend and deepen a friendship, just follow these steps.
Keep your promises.
Don’t ever make a promise that you can’t keep. If you say you’ll hang out with a friend and an unexpected situation arises, explain the situation. Give your friend a gift and tell him or her you are sorry. Nobody is perfect, and it’s okay if you break a promise once in a blue moon. 2.__
Apologize when you’ve made a mistake.
3. Though your friend won’t be happy that you made a mistake, he or she will be very pleased that you admit it instead of just pretending that nothing is wrong.
4.
To be truly supportive, you will have to be able to watch out for your friend when he/she is having a difficult time. If you sense that your friend is getting into some trouble, help him or her away from the situation by not being afraid to speak up about it.
Give your friend some space when he or she needs it.
Part of being supportive means supporting the fact that your friend won’t always want to spend time with you. Learn to step back and give your friend space. 5. ___ Don’t be jealous (嫉妒的) if your friend has lots of other friends.
A. However, don’t make it a regular thing.
