Read carefully the following excerpt and then write your response in NO LESS THAN 200 words, in which you should: ●summarize the main message of the excerpt, and then ●comment on whether our brains will get lazy in a world run by intelligent machines. You can support yourself with information from the excerpt. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. With intelligent machines to do the thinking, will our brains get lazy？ Changing technology stimulates the brain and increases intelligence. But that may only be true if the technology challenges us. In a world run by intelligent machines, our lives could get a lot simpler. Would that make us less intelligent？ Artificial intelligence is taking over many human jobs. For instance, planes are being flown much of the time by automatic pilots. And the complex problem of controlling air traffic around large modern airports is also achieved by artificial intelligence that operates well beyond the capacity of mere human air traffic controllers. As machines get smarter, they will do more of our thinking for us and make life easier. In the future, the electronic assistant will develop to the point that it serves similar functions as a real living butler, fulfilling requests such as: “Organize a dinner party for six on Thursday, Jeeves, and invite the usual guests.” At that point, our long struggle with challenging technologies is at an end. Like Be Wooster, we can take it easy knowing that the hard work of planning and organizing is being done by a better brain-the electronic assistant. Starved of mental effort, our brains will regress.

f time elapses, however, the numbers are erased from the memory. How did the information get there in the first place？ Information that makes its way to the short term memory (STM). does so via the sensory storage area. The brain has a filter which only allows stimuli that is of immediate interest to pass on to the STM, also known as the working memory.

There is much debate about the capacity and duration of the short term memory. The most accepted theory comes from George A. Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or name rather than just a letter or number. Modern theorists suggest that one can increase the capacity of the short term memory by chunking, or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage.

When making a conscious effort to memorize something, such as information for an exam, many people engage in "rote rehearsal". By repeating something over and over again, we are able to keep a memory alive. Unfortunately, this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, you might attempt to remember a phone number by repeating it aloud. If the doorbell rings or the dog barks to come in before you get the opportunity to make your phone call, you will forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice "elaborate rehearsal". This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories.

Encoding information semantically also makes it more retrievable. Retrieving information can be done by recognition or recall. Humans can recall memories that are stored in the long term memory and used often. However, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures. , the more likely a memory can be retrieved. This is why multiple choice tests are often used for subjects that require a lot of memorization.

According to the passage, how do memories get transferred to the STM？ ______

A．They revert from the long term memory.

B．They are filtered from the sensory storage area.

C．They get chunked when they enter the brain.

D．They enter via the nervous system.

eve, is an unfortunate victim of adverse circumstances, deprived of one of the greatest twentieth-century opportunities. Convinced of the importance of education, modern states " invest " in institutions of learning to get back "interest" in the form. of a large group of enlightened young men and women who are potential leaders. Education, with its cycles of instruction so carefully worked out, punctuated by textbooks—that purchasable wells of wisdom—what would civilization be like without its benefits？

So much is certain: that we would have doctors and preachers, lawyers and defendants, marriages and births—but our spiritual outlook would be different. We would lay less stress on "facts and figures" and more on a good memory, on applied psychology, and the capacity of a man is to get along with his fellow-citizens. If our educational system were fashioned after its bookless past we would have the most democratic form. of "college" imaginable. Among tribal people all knowledge inherited by tradition is shared by all; it is taught to every member of the tribe so that in this respect every- body is equipped for life.

It is the ideal condition of the "equal start" which only our most progressive forms of modern education try to regain. In primitive cultures the obligation to seek and to receive the traditional instruction is binding to all. There are no "illiterates"—if the term can be applied to peoples without a script—while our own compulsory school attendance became law in Germany in 1642, in France in 1806, and in England in 1876, and is still non-existent in a number of "civilized" nations. This shows how long it was before we deemed it necessary to make sure that all our children could share in the knowledge accumulated by the "happy few" during the past centuries.

Education in the wilderness is not a matter of monetary means. All are entitled to an equal start. There is none of the hurry, which, in our society, often hampers the full development of a growing personality. There, a child grows up under the ever-present attention of his parents' and therefore the jungles and the savannahs know of no "juvenile delinquency". No necessity of making a living away from home results in neglect of children, and no father is confronted with his inability to "buy" an education for his child.

Why do modern states invest in institutions of learning？

A．To get a repayment for what an individual's education has cost.

B．To get rewards for what they have spent.

C．To charge interest.

D．To give all the children free education.

Passage Two

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.

Previous behavioural 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 you lost your bank card. The new card you receive will come with a new personal identificatipn number (PIN). Each time you remember the new PIN, you gradually forget the old one. This process improves access to 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 brain 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, as 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.
