Many people, including some policemen, believe eye contact is a good test of honesty. If someone can't look at you directly in the eye, then he or she is not playing honestly, they insist. After many experiments, however, a number of experts have found out that good liars can make false eye contact.Eye contact, though not a sure sign of dishonesty, is a clear way to show interest in another person. When a person looks at you and continues to do so, you know his attention is placed on you. When he turns his head away, his mind is probably elsewhere. But there are exceptions. A shy person may have trouble making and keeping eye contact, no matter how interested he is in the other person. And certain nationalities, such as the British and Germans, are much less oriented to eye-to-eye contact than, say, the French and the Arabs.Eye contact should be natural, not forced or overdone.Have short periods of eye contact while you watch other parts of the person's face — especially the mouth. When the person smiles, be sure to smile back. But always make an effort to return your gaze to the person's eyes as she speaks. It is common to look up, down, and all around when speaking to others, and not have eye contact at all times.Too much eye contact, especially if it is forced, can work against you. If you stare at a person, or leer in a suspicious way, the other person may feel uncomfortable and even suspicious about your intent. A fixed stare can seem like aggressive behavior. if it is a challenge as to who will look away first.(1)Many people believe that eye contact is a sign of ___________.A、honestyB、dishonestyC、attentionD、A and C(2)According to the passage, which of the following statements is NOT true?A、Eye contact is a way to show interest in another person.B、When a person looks at you, his attention is placed on you.C、When a person fails to make eye contact, he is definitely not interested in you.D、It is common to look up, down, and all around when speaking to others.(3)While we watch other person's face, we should have short periods of eye contact with, especially, other people's _____________.A、eyesB、noseC、mouthD、ears(4)Which of the following statements is TRUE according to the passage?A、Eye contact is not a good test of honesty.B、Some people may have trouble making and keeping eye contact, no matter how interested he is in the other person.C、If someone can look at you directly in the eye, he or she is playing honestly.D、A number of experts have found out that no one can make false eye contact.(5)This passage mainly discusses ________________.A、how to test one is honest or not by the way of eye contactB、how to make eye contactC、how to avoid too much eye contactD、the function of correct eye contact

AWeather has a great influence(影响) on people．It influences people's health, intelligence (智力) and feelings．In August, it is very hot and wet in the southern part of the United States．People there have heart disease and other kinds of health problems during this month． In the Northeast and Middle West, it is very hot at some times and very cold at other times．People in these places may have heart disease after the weather changes in February or March．The weather can also influence intelligence． For example, in a 1982 study by scientists, the in scores of a group of students were very high during a storm, but after the storm their IQ scores were lower than usual level． So storms can increase intelligence．However, very hot weather can lower it． Students in the United States often do badly on exams in the hot months of the year．Weather also has a strong influence on people's feelings．Winter may be a bad time for thin people．They usually feel cold during these months and they may feel unhappy during cold weather． In hot summer weather, on the other hand, fat people may feel unhappy． The sum- mer heat may make them tired and they are easy to get angry．( )21．lf thin people feel unhappy, the weather may be very _________．A．warmB． coldC． coolD． hot

-Larry is the biggest airhead I've ever met. He always makes careless mistakes, and he's a pain to work with. - ________ . You'll always have some co-workers that are harder to work with than others, you know.：A I have the same feeling to you ;B You really have it ;C You shouldn't be so negative
The process of perceiving others is rarely translated(to ourselves or others) into cold,objective terms．"She was 5 feet 8 inches tall, had fair hair, and wore a colored skirt．" More often, we try to get inside the other person to pinpoint his or her attitudes, emotions, motivations,abilities, ideas, and characters． Furthermore, we sometimes behave as if we can accomplish this difficult job very quickly--perhaps with a two-second glance．We try to obtain information about others in many ways． Berger suggests several methods for reducing uncertainties about others; who are known to you so you can compare the observed person's behavior with the known others' behavior, observing a person in a situation where social behavior is relatively unrestrained or where a wide variety of behavioral responses are called for,deliberately structuring the physical or social environment so as to observe the person's responses to specific stimuli, asking people who have had or have frequent contact with the person about himor her, and using various strategies in face-to-face interaction to uncover information about another person--question, self-disclosures, and so on．Getting to know someone is a never-ending task, largely because people are constantlychanging and the methods we use to obtain information are often imprecise． You may have known someone for ten years and still know very little about him． If we accept the idea that we won't ever fully know another person, it enables us to deal more easily with those things that get in the way of accurate knowledge such as secrets and deceptions． It will also keep us from being too surprised or shocked by seemingly inconsistent behavior． Ironically, those things that keep us from knowing another person too well (e． g． secrets and deceptions) may be just as important to the development of a satisfying relationship as those things that enable us to obtain accurate knowledge about a person (e． g． disclosures and truthful statement)．Some people are often surprised by what other people do． According to Berger, that is mainly because__________．A.some people are more emotional than othersB.some people are not aware of the fact that we will never completely know another personC.some people are sensitive enough to sense the change of other people's attitudesD.some people choose to keep to themselves
共用题干Aromatherapy(芳香疗法)1.Aromatherapy is a form of alternative medicine which is based on the use of very concentrated essential oils from the flowers,leaves,bark,branches or roots of plants which are considered tohave healing properties.In aromatherapy these powerful oils are mixed with other oils,such as almond(杏仁)oil,or the are diluted(稀释)with water.These solutions(溶液剂)can be rubbed on the skin,sprayed in the air,or applied as a compress（敷药）.2.Many people have aromatherapy massages（按摩）,and depending on the treatment a person is having,the aromatherapist will massage the oil into the hands or shoulders.The massage is smooth and flowing,as it is designed to create a sense of relaxation and calm.The sessions are tailored to the individual's health and mood at the time,so every session is unique.3.Practitioners of aromatherapy believe that the aroma of the essential oils directly stimulates the brain or that the oils are absorbed through the skin into the bloodstream,where they can affect the whole body and promote healing.Other claims in support of aromatherapy are that it aids digestion,improves the functions of respiratory system,reduces muscular aches and pains,and promotes muscle relaxation and tone.It has also been argued that aromatherapy can improve circulation,lower blood pressure,and help combat insomia （失眠）and other stress-related disorders such as tension headaches , anxiety , and mild depression.4.However,while aromatherapy may have real effects that promote a sense of well-being,some traditional medicine practitioners remain doubtful about its powers.While research has confirmed that aromatherapy does have some positive short-term effects on most people,it also suggests that aromatherapy is not an actual science or medicine that should be used to treat illness.Furthermore,not all aromatherapy is considered beneficial to health.There are precautions which should be taken before having aromatherapy because some oils can have negative effects on people with certain medical conditions.The study of aroma-therapy is relatively new and unexplored.More research needs to be conducted to make scientific conclusions about its use and effects.The uses and benefits of aromatherapy need to_____.A:suit different peopleB:be further exploredC:help the disabledD:be used externallyE:have healing effectsF:be promoted
共用题干第二篇Love or Hate?We have saved as a final set of emotions to two most important emotions connected with other people:love and its opposite,hate.Love can be seen everywhere.Yet surprisingly,love has been the subject of less scientific research than other emotions,such as anger and fear. The reason for this may be two fold.Firstly,love is a very complex emotion,difficult to describe and measure. Secondly,unlike many radical emotions,radical love is generally not a problem. Thus less medical attention has been paid to it.What is love?This is a complex question and requires a complex answer. Love is a strong,positive attraction and feeling for another person or thing. But it is more than this.It also involves feeling of caring,protection,excitement,and tenderness.When two people are in love,they feel drawn to one another;they greatly enjoy each other's company;and they may be sexually attracted to one another.Sometimes it is easier to think in terms of different kinds of love:romantic love,brotherly love, and so forth.Though they are different in some respects,they share one important characteristic: a strong positive feeling toward another.Our feelings toward other people are often complex.We may love someone and,at the same time,be angry with him.Or we may love someone,even though we are jealous of him.We mighi even love someone and,at the same time,hate for some precise reason.Hate is a strong negative emotion toward someone,and is due to anger,jealousy,or some other factor. Like love,hate can be a very strong emotion.It can also be very dangerous.The question is often asked,"Is it bad to hate?"The best answer is probably" sometimes yes and sometimes no." Usually hate does not help us.It makes us feel unhappy and makes us do things that may hurt others.However,sometimes it may be necessary to hate and hurt someone in order to protect loved ones.Which of the following is true?A:Love has been the subject of less scientific research because it is too simple an emotion.B:Radical love is so difficult to describe and measure that less medical attention has been paid to it.C:To hate is always too bad.D:We can have at the same time two opposite feelings for another.

资料：No matter how carefully you pick the members on your team,you may still end up with a negative employee.These workers don’t necessarily fall into the category of “toxic,”but they’re just kind of a drag with their cynical, pessimistic worldview.If you ‘re dealing with a negative employee,here are 3 steps to take.FIND OUT WHYIf you decide to proceed in addressing the behavior,think about whether there have been behavior changes recently.Is the negativity a constant or has the behavior escalated?If the latter ,was there an event that led up to the change?Individuals in the workplace live multi-dimensional lives,and other non-workplace stresses may impact work productivity and mood.In an April 2016 report in the Journal of Managerial Psychology,a team of Toronto researchers found that employee who are cynical of their workplace may feel more positive if their managers are supportive.DISCUSS GOALSWhen discussing the situation with your negative employee,it is recommended to frame the discussion in the context of the Individual’s goals.”Tone policing” where you simply point out pessimistic commentary without addressing the root cause, rarely works and may just cause more resentment.Get to the root of the issue and find out if the employee needs additional training,perhaps in management or communication skills,to overcome a deficit.ADDRESS ISSUESA direct,solutions-oriented conversation with the employee can uncover problems or circumstances driving the behavior.If there are workplace issue that can be solved,consider doing so if it make sense.If there are personal issues that have caused an escalation in negative behavior,examine whether accommodations can be made to help the person while they’re going through such challenges.Some employees don’t have great interpersonal skills,and putting them in jobs where they are more focused on job-related tasks than on interactions with others can be an effective solution,too. According to paragraph four ,what is NOT a solution to the negativity?A.Help solve the workplace disputes for the negative employee.B.Put the negative employee in a suitable working position.C.Have the negative employee’s colleagues to avoid arguments with him/her.D.Support the negative employee to go through challengses outside the office.

资料：Dream is a story that a person watches or even takes part in during sleep. Dream events are imaginary, but they are related to real experiences and needs in the dreamer's life. They seem real while they are takingplace. Some dreams are pleasant, others are annoying, and still others are frightening. Everyone dreams, but some persons never recall dreaming. Others remember only a little about a dream they had just before awakening and nothing about earlier dreams. No one recalls all his dreams.Dreams involve little logical thought. In most dreams, the dreamer cannot control what happens to him. The story may be confusing, and things happen that would not happen in real life. People see in most dreams, but they may also hear, smell, touch, and taste in their dreams. Most dreams occur in color. But persons who have been blind since birth do not see at all in dreams.Dreams are a product of the sleeper's mind. They include events and feelings that he has experienced. Most dreams are related to events of the day before the dream and strong wishes of the dreamer. Many minor incidents of the hours before sleep appear in dreams. Deep wishes or fears-especially those held since childhood-often appear in dream. and many dreams fulfil such wishes. Events in the sleeper's surrounding-a loud noise, for example, may become part of a dream, but they do not cause dreams. Some dreams involve deep feeling that a person may realize he has. Psychiatrists often use material from a patient’s dreams to help the person understand himself better. Dreaming may help maintain good learning ability, memory, and emotional adjustment. People who get plenty of sleep-but are awakened each time they begin to dream-become anxious and restless.According to the passage, dreams result from ______.A.the sleeper’s own mindB.the sleeper’s feelingC.the sleeper’s imaginationD.the sleeper’s wishes

共用题干Parkinson's Disease1 Parkinson's disease affects the way you move.It happens when there is a problem with certain nerve cells in the brain. Normally , these nerve cells make an important chemical called dopamine（多巴胺）. Dopamine sends signals to the part of your brain that controls movement.It lets your muscles move smoothly and do what you want them to do.When you have Parkinson's,these nerve cells break down.Then you nolonger have enough dopamine,and you have trouble moving the way you want to.2 No one knows for sure what makes these nerve cells break down.But scientists are doing a lot of research to look for the answer. They are studying many possible causes,including aging and poisons in the environment.Abnormal genes seem to lead to Parkinson's disease in some people.But so far,there is not enough proof to show that it is always inherited.3 Tremor（颤抖）may be the first symptom you notice.It is one of the most common signs of the disease,although not everyone has it.Tremor often starts in just one arm or leg or only on one side of the body.It may be worse when you are awake but not moving the affected arm or leg.It may get better when you move the limb or when you are asleep.In time,Parkinson's affects muscles all through your body,so it can lead to problems like trouble swallowing or constipation（便秘）.In the later stages of the disease,a person with Parkinson's may have a fixed or blank expression,trouble" speaking,and other problems.Some people also have a decrease in mental skills.4 At this time,there is no cure for Parkinson's disease.But there are several types of medicines that can control the symptoms and make the disease easier to live with.You may not even need treatment if your symptoms are mild.Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life.Your doctor will adjust your medicines as your symptoms get worse.You may need to take several medicines to get the best results.A person with Parkinson's has to learn to live with the disease,__________.A:what affects muscles all through your bodyB:if there isn't enough dopamine in your bodyC:which cannot be cured yetD:which may be the first symptom you noticeE:if you have a fixed or blank expression F: what causes Parkinson's disease
