4. . Passage Twenty All friendships require a certain amount of chemistry. But when two people of the opposite sex become friends， sometimes those friendly feelings can start to resemble something more like sexual tension. Male-female friendships can be an emotional minefield of hidden desires. Does this mean you secretly want to jump into bed with all of your friends? Of course not. But do you ever wonder how many of them might be interested if the opportunity presented itself? Maybe you and your platonic (柏拉图式的) friendship are just a bad breakup and a bottle of wine away from crossing that boundary and hooking up (结合). So can two people of the opposite sex ever really be “just friends?” The Hollywood answer to this age-old question is a decisive HELL NO. On screen， male-female friendships always turn into something more. Harry and Sally， Chandler and Monica， Jim and Pam … … Do I need to go on? Even the characters in Just Friends wind up becoming much more than the film’s definitive title suggests. Cinematic stories dictate that when reasonably attractive men and women befriend one another， they are always on the road to romance， whether they realize it or not. But how much truth is there to this friendship as foreplay theory? It is not a whole lot. Real life isn’t a romantic comedy. Men and women go to school together， work together and hang out in plenty of platonic settings without falling hopelessly in love with one another. Last year， a close female friend of mine moved in with a new male roommate. My immediate reaction was， “You two are definitely going to sleep together.” It seemed to me that a single man and woman living under the same roof would inevitably end up doing it. Much to my surprise， the roommate romance never happened. Almost one year later， the two of them have never even come close to seeing each other naked. Instead， their way of life has come to resemble a sexless marriage. They cook for each other， argue over domestic chores and insist that they never， ever think about each other “that way.” In real life， Hollywood foreplay theory ( ) .

3. Passage Twenty-Four Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas， more disagreements in interest， and more groups and organizations with different beliefs. In addition， there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways， there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory， they are at least customary and undisputed. Within a society， social changes is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material， for example， in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements. Furthermore， social change is easier if it is gradual. For example， it comes more readily in human relations on a continuous scale rather than one with sharp dichotomies ( 一分为二). This is one reason why change has not come more quickly to Black American as compared to other American minorities， because of the sharp difference in “appearance between them and their white counterparts” .According to the passage， which of the following is NOT true?

A. Social change tends to meet with more difficulty in basic and emotional aspects of society.

B. Disagreement with an argument about conditions tend to slow down social change.

C. Social change is more likely to occur in the material aspect of society.

D. Social change is less likely to occur in what people learned when they were young.

5. Passage Twenty-Five Online dating has just been revealed to be one of the most common ways to start a relationship. But new research reveals that the concept is still highly flawed (有缺陷的). An analysis of 400 studies into online dating shows that while it offers access to plenty of other singles， users can be overwhelmed and put off by the volume of choice， defeating the purpose. The research， by Northwestern University and published in the journal Psychological Science in the public interest， found that the processes involved don’t lend themselves to forming strong relationships. The findings also indicated that the concept of an online profile (介绍) is not entirely useful and “can result in treating potential partners as mere objects ”. Lead author Eli. J. Finkel explained， “Online dating is a terrific addition for singles to meet. However， there are two problems. ” First， studying over seemingly endless lists of profiles of people one does not know， as on Match.com， does not reveal much about them. Second， it “overloads people and they end up shutting down，” he said. He compared it to shopping at “supermarkets of love” and said psychological research shows people presented with too many choices tend to make lazy and often poor decisions. The study’s authors also questioned the algorithms ( 算法) employed by sites such as eHarmony.com to match people based on their interests or personality—comparing it to having a real estate agent of love. While the algorithm may reduce the number of potential partners from thousands to a few， they may be as unsuitable for each other as two people meeting at random， Dr. Finkel explained， adding the chances are no better than finding a relationship by walking into any bar. “There’s no better way to figure out whether you’re a match with somebody than talking to them over a coffee or beer，” Dr. Finkel said. According to Dr. Finkel， what is the best way to find a match?

A. An evaluation on the basis of interests and personality.

B. An analysis based on proper computer algorithms.

C. A comparison with other potential partners.

D. A face-to-face talk with the potential partner.
