单选题 Much meaning can be 26 , clearly, with our eyes, so it is often said that eyes can speak. Do you have such kind of experience? In a bus you may look at stranger, but not too long. And if he is 27 that he is being stared at, he may feel uncomfortable. The same is in daily life. If you are looked at for more than necessary, you will look at yourself up and down, to see if there is anything wrong with you. If nothing goes wrong, you will feel angry toward other's 28 with you that way. Eyes do speak, right? Looking too long at someone may seem to be rude and 29 . But things are different when it comes to stare at the opposite sex. If a man glances at a woman for more than 10 seconds and refuses to 30 his gaze, his intentions are obvious, that is, he wishes to attract her attention, to make her understand that he is admiring her. However, the normal eye contact for two people 31 in conversation is that the speaker will only look at the listener from time to time, in order to make sure that the listener does pay attention to what the former is speaking, to tell him that he is 32 . If a speaker looks at you continuously when speaking, as if he tries to 33 you, you will feel disconcerted. A poor liar usually exposes himself by looking too long at the victim, since he believes in the false idea that to look straight in the eye is a sign of honest communication. Quite the contrary. In fact, continuous eye contact is 34 to lovers only, who will enjoy looking at each other tenderly for a long time, to show. 35 that words cannot express. A. dominate B. engaged C. suitable D. affection E. confined F. observation G. stare H. hostile I. attentive J. aggressive K. sensing L. avert M. attract N. received O. conveyed

单选题Although most birds have only a______sense of smell, they have acute vision.

单选题 Most people can remember a phone number for up to thirty seconds. When this short amount of 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.
