7.Memory is the ability to keep track of things that have happened in the past. Memory really isleaning. One needs memory to ride a bicycle. A dog needs to remember if it is to come when called.Memory is said to be stored in the brain as a “memory trace (记忆痕) .” What makes up this traceis not known. Some scientists believe that certain chemical substances may carry certain memories.For example, one substance, when given to rats, causes them to dear the dark.Other research into memory has to do with how the brain works. Psychologists use three meansto find out how a person remembers. For example, give a person a grocery list. Let the personmemorize the list, then put it away. The most natural way to find out how much a personremembers of the grocery list is to ask what he or she remembers. This is called the method ofrecall. Another method is called recognition. Gibe the person another grocery list. Ask him or herto choose items on the first list from the items that are on only the second list. Often a person willbe able to recognize thins that he or she cannot recall. A third method of finding how much aperson remembers is called relearning. Here the person is asked to read over the first list. Theperson will probably learn the list the second time faster than he did the first time. The differencein the time it takes to relearn the list is thought of as a measure of how much a person hasremembered.One way of remembering something is to repeat it many times. Interest is very important. Boringlists of facts are much more difficult to remember than something that we understand and areinterested in. Motivation, or wanting to do something, is also important. Motivation is linked withreward. For example, a hungry animal quickly learn how to do something if that action gets theanimal food. In humans, wanting to learn is often motivation. The praise of a teacher or theknowledge that an answer is correct is rewarding.We can learn from the 2nd paragraph that_____.

14.“If there is one thing I’m sure about, it is that in a hundred years from now we will still be reading newspapers．It is not that newspapers are a necessity．Even now some people get most of their news from television or radio．Many buy a paper only on Saturday or Sunday．But for most people reading a newspaper has become a habit passed down from generation to generation． The nature of what is news may change．What basically makes news is what affects our lives — the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same．I think there will be more coverage of scientific research, though．It’s already happening in areas that may directly affect our lives, like genetic(基因) engineering．In the future, I think there will be more coverage of scientific explanations of why we feel as we do — as we develop a better understanding of how the brain operates and what our feelings really are． It’s quite possible that in the next century newspapers will be transmitted(传送) electronically from Fleet Street and printed out in our own home．In fact, I’m pretty sure that how it will happen in the future．You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read — sports and international news, et C． I think people have got it wrong when they talk about competition between the different media(媒体)．They actually feed off each other．Some people once foresaw that television would kill off newspapers, but that hasn’t happene D．What is read on the printed page lasts longer than pictures on a screen or sound lost in the air．And as for the Internet, it’s never really pleasant to read something just on a screen．[单选题] What is the best title for the passage?
