The brain is a seemingly endless library, whose shelves house our most precious memories as well as our lifetime’s knowledge. But is there a point where it reaches capacity. The answer is no, because brains are more sophisticated than that. Instead of just crowding in, old information is sometimes pushed out of the brain for new memories to form. Precious behavioral studies have shown that learning new information can lead to forgetting. But in a new study, researchers demonstrated for the first time how this effect occurs in the brain. In daily life, forgetting actually has clear advantages. Imagine, for instance, that just lost your bank card. The new card you receive will come with a new personal identification number(PIN). Each time you remember the new PIN, you gradually forget the old one. This process improves access to the relevant information, without old memories interfering. And most of us may sometimes feel the frustration of having old memories interfere with new, relevant memories. Consider trying to remember where you parked your car in the same car park you were at a week earlier. This type of memory (where you are trying to remember new, but similar information) is particularly vulnerable to interference. When we acquire new information, the main automatically tries to incorporate(合并) it within existing information by forming associations. And when we retrieve(检索) information, both the desired and associated but irrelevant information is recalled. The majority of previous research has focused on how we learn and remember new information. But current studies are beginning to place greater emphasis on the conditions under which we forget, and its importance begins to be more appreciated. A very small number of people are able to remember almost every detail of their life. While it may sound like an advantage to many, people with this rare condition often find their unusual ability burdensome. In a sense, forgetting is our brain’s way of sorting memories, so the most relevant memories are ready for retrieval. Normal forgetting may even be a safety mechanism to ensure our brain doesn’t become too full. What does the passage say about forgetting?
A、It can enlarge our brain capacity.
B、It helps get rid of negative memories.
C、It is a way of organizing our memories.
D、It should not cause any alarm in any way.
me of medical science. Activists deny that we are trying to help and say it is () of our evil and cruel (). A more reasonable argument, however, can be advanced in our (). Life is often () to animals and human beings. Teenagers are flung from trucks and suffer severe head (). Young children () able to walk find themselves at the bottom of swimming pools while a parent is occupied with something else. From everyday germs to gang (), no life is free of pain. Physicians hoping to relieve the eternal suffering of these tragedies have only three choices: 1) create an animal model of the problem to understand the process and test new therapies; 2) experiment on human beings (some experiments will succeed, most will fail); or 3) leave medical knowledge static, hoping that () discoveries will lead us forward.
We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology,more and more features are being added to the mobile phones which make them more useful. In addition to making calls,mobile phones also support a wide variety of other services such as text messaging,email,Internet access,business applications,gaming and photography. We can bring them everywhere,and can be reached by others anytime. They make the world smaller,bringing people together no matter where they are.
But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.
Since there are so many risks,why do we still have mobile phones?This is because these risks or disadvantages can be overcome. For example,while we are driving we can easily pull up our car if we really need to use the phone. Mobile phone manufacturers are reducing the radiation of mobile phones to avoid health risks.
Though there are both pros and cons of using mobile phones,we could easily see that there are more advantages than disadvantages. Moreover,mobile phones are becoming cheaper,which might be another reason why mobile phones are increasingly used today.
1. Which of the following functions is NOT mentioned in the passage?
A. Text messaging.
B. Camera.
C. GPS.
2. What risks might mobile phones cause?
A. Traffic accidents and health problems.
B. Environmental damage.
C. Both A and B.
3. What are mobile phone manufacturers doing to prevent mobile phone users from health risks?
A. They are reducing the radiation of mobile phones.
B. They are trying to persuade people to use mobile phones less.
C. They are developing new models of mobile phones.
4. Why do people still use mobile phones despite their disadvantages?
A. Because people don’t believe that mobile phones have any disadvantages.
B. Because the disadvantages of mobile phones can be avoided.
C. Because people cannot live without mobile phones.
5. According to the last paragraph,why are mobile phones increasingly being used today?
A. They are safer.
B. They have more functions.
C. They are becoming cheaper.
Twenty years ago, our classroom was a lot less pleasant.Very old-fashioned.We had fewer window, for example.There were five rows of desks, six desks in a row.Since everything was nailed to the floor, a student sat in the same place all day long.Oh, we had to be very strict.Now students move all over the room.They go to different areas for different subjects, and they write at these movable desks.The students are more mobile, and beca use they’re more mobile, they’re less restless, and because they’re less restless, they are more attentive.At least that’s the theory.And as a matter of fact, we really don’t have many behavior. problems here.
We use a modified open classroom system here at the James.I’ll try to explain what that means.Each student makes a work contract with his teacher.Basically, he agrees to a certain amount of work on a certain project.He hands the work in when he gets it done.He works at his own speed and plans h is own time.If he is particularly motivated in one subject—math, for instance—he can explore the subject more thoroughly than the others.But he must also complete his contract in arts or reading or social science.Freedom within a structured system: that ’s what we are trying to offer.
