Passage Two Questions 16 to 20 are based on the following passage. Biologists believe that love is fundamentally a biological rather than a cultural construct. That is because the capacity for love is found in all human cultures and similar behavior is found in some other animals. But what does science have to say about the notion of love at first sight? In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love a dozen different parts of the brain work together to release chemicals that trigger feelings of euphoria (愉快), bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with sexual, pair-bonding love. In fact, the desires, motivations and withdrawals involved in love have a great deal in common with addiction. What this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a fraction of a second how attractive they find another person. Ayala, a psychologist at Ben-Gurion University, also found in a survey that a small fraction (11%) of people in long-term relationships said that they began with love at first sight. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers. One might also speculate that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned only with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships. 16.
