第 48 至 51 題為題組 Many of us have probably experienced déjà vu at least a few times in our life. Its meaning comes from the phrase "already seen" in French, and occurs when we feel that a person, place, or thing is familiar to us without actually having experienced them before. This strange phenomenon happens to as much as 70 percent of the population, but a higher number of 15 to 25 year olds experience it than any other age group. Maybe you just travelled to a new foreign country, and it just felt very familiar to you. Yes, you are feeling déjà vu; however, you know you haven't been there before. While different people experience déjà vu in different ways, it is still a pretty mysterious phenomenon, and researchers are putting the pieces together. Based on some studies, déjà vu is just a part of having a healthy memory checking system, and people who experience déjà vu more often are less likely to forget the details of important events. In fact, the results of the study don't look too promising in terms of mental health for people who never experience déjà vu. Scientists believe déjà vu is created by a neurological anomaly related to an improper electrical discharge in the brain. In short, it's not a mystical prophecy or out-of-body experience, but just your brain playing a trick on you; that is, these scientists dismiss it as just a glitch in the matrix. A few people are just terrified when it happens, but others feel euphoric about it. On average, most people just find it to be a perplexing sensation, neither pleasant nor threatening. Since déjà vu occurs in individuals with and without a medical condition, there is much speculation as to how and why it happens. Several psychoanalysts attribute deja vu to simple fantasy or wish fulfillment, while some psychiatrists ascribe it to a mismatching in the brain that causes it to mistake the present for the past. Many parapsychologists believe it is related to a past-life experience. Obviously, there is more investigation and researches to be done. So, does this article seem very familiar to you? 48. Which of the following CAN'T be described as a déjà vu experience based on this passage? (A) You keep buying similar style of clothing and you don't know why. (B) You feel you've been to a place when actually it's your first time there. (C) Someone looks familiar to you though you have never seen him before. (D) You just met a new friend whom you think you must have met somewhere. 49. Based on the article, which description about déjà vu is WRONG? (A) It actually is not as harmful to our mental health as we think. (B) Some people who have experienced it may feel a sense of happiness. (C) The word"déjà vu" originates from France, meaning"already seen." (D) Those who never experience it may not be mentally healthier than those who do.
