People lie all the time, but depending on how skilled they are, it can be difficult to determine when someone is lying to you. Do you know how to recognize the signs that someone is lying to you? Some of the signs are obvious while others are more subliminal(难以察觉的), but there are ways to catch someone in a lie, you just need to know what they are. {#blank#}1{#/blank#}

1） Liars make false eye contact.

    A person who is lying to you won't make eye contact with you or they make too much eye contact. If a person is lying they may feel you are watching him and he will look down at the floor or away from your eyes. Some people try to stare you in the face deliberately. {#blank#}2{#/blank#}

2）Liars avoid using contractions(缩略形式)

    The liar will say “I did NOT notice that.” instead of “I didn't notice that.”{#blank#}3{#/blank#} Usually it ends up making the story a lot less believable.

3）Unnatural Body Language.

    Liars often feel uneasy, turn away from the person to whom they are speaking, blink(眨眼) rapidly, smile less and have pitch changes in their tone of voice. They may cross their arms which is a sign of being “closed” or trying not to reveal too much information. {#blank#}4{#/blank#} They could touch parts of their face, an ear or a nose or play with keys or another item that they have in their hand.

4）Liars provide additional information without being asked for it

    {#blank#}5{#/blank#}The result is the more complicated the story is, the less believable it will be. You will have the feeling that nothing could be further from the truth.

A. This is an attempt by the liar to be absolutely clear what they mean.

B. Here are some easy ways to recognize liars and catch lies.

C. Sometimes people look unnatural when they are lying

E. They seem to think that by telling their story in detail, you will find it more believable.

F. They try to change the subject or move the conversation in a different direction

G. In this way they feel like making eye contact will make what they are saying more believable.

    Do you usually feel you're working hard but still can't reach your study goals? Here are some quick tips to help you study better.

Study with a partner or in groups

    Rather than living in a cave with your nose in the books all day, grab a friend from your class and study with him.{#blank#}1{#/blank#}

Step into your teacher's shoes

    Ask yourself “If I were the teacher, what would I put on the test?”You have probably experienced a lot of your teacher's tests and quizzes by now.{#blank#}2{#/blank#}Teachers have specific types of information that they want you to learn. The structure is usually the same.

Paint pictures on the paper

    You can build your knowledge structure in the form of pictures. It's harder to remember each piece of a puzzle individually than it is to recall the completed picture.{#blank#}3{#/blank#}

    A hungry brain is an ineffective one. Your brain needs the proper nutrients to keep it going. Because of this, what you eat and drink also play a huge role in how sharp your brain is. Healthy food provide nutrients to your brain cells to keep them energized.

Take breaks to relax your brain

    Your brain is like a muscle. It can be also tired if you overwork it,{#blank#}5{#/blank#}If you divide studying into 15 to 30 minutes blocks with quick breaks in between, your brain will feel refreshed, grateful and ready for the next challenge you throw at.

A. Feed your brain from time to time.

B. It needs exercise to make it stronger.

C. Relax your brain by eating and drinking.

D. You'd better learn from them for the next test.

E. It's necessary to have a long holiday and have nice food.

F. Find ways to connect what you are learning to real life or to other concepts.

G. Group studying helps you to engage and process the information more deeply

    A 12-year-old with end stage cancer, the child's parents had recently moved her from the hospital to her home in the suburbs of Los Angeles. Some days later the girl's breath quickened, and her father phoned the family's hospice nurse. Please come, he said.

    The nurse knew the visit would require more than four hours of her time: a two-hour drive in each direction, plus her time with the girl. Why don't we connect over FaceTime, she asked. The father agreed, and they connected.

The nurse asked the father to move his daughter gently to her side, then to her back, to lift the child's shirt. The nurse would ask: What do you see, what concerns you, and the father would explain. In this fashion the pair examined the girl — the nurse on her computer, the father his iPad. Together they decided that the nurse's presence was not necessary, that the child had more time.

    Later, the father reported feeling comforted by the nurse. He appreciated her availability, the fact that she could see what he saw, and their ability to discuss it in real time.

Telemedicine has become a trend in America. Some hospitals have gone so far as to specially design telemedicine clinics. The room is staged like an office but with better lighting. There's a nice desk for the clinician to sit behind, a computer situated stage left, and books in the background. A physician taking a video call from home might wear a pair of headphones, equipped with a mic — to ensure whatever the patient says isn't broadcast to anyone off-camera.

    However, there is something more than the technology bit. According to David, the head of the telemedicine pilot the girl's family had been part of, there are some people who are great in person and you put them on camera they're a dead fish. “Some physicians are camera shy. For others, the physical isolation can actually help them be more empathetic.” He adds.

    “My experience is that, once you get past some initial hurdles, you can maintain an intimate, immediate connection with patients that in some cases may be more useful than even in-person interactions,” David says.

    Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity (湿度).

In very cold climates, there is a constant danger of developing hypothermia, which is a life-threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0℃. However, differences in persons and even the time of day can cause it to be as much as 6℃ higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4℃. Below 29.4℃, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6℃. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7℃.

In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life-threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7℃. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.

    When you visit America, you will see the word Motel on signs and notice boards. It is made up of "motor" and "hotel" and it is really a hotel for people who arrive by car (however, you don't need a car to stay at one). You have to pay when you arrive for your room, which usually has a bath. Meals are not provided, but there will certainly be a cafeteria (自助餐馆). Americans eat a lot of salads and sandwiches. Along the main roads there are a lot of motels. Each tries to offer more than next. Some provide television in every bedroom; others have swimming pools; and so on. Motels are especially useful when you are in the country, far from a town or city. You will also find them in the big National Parks.

    In these great National Parks, you may meet guests you don't expect to see. An American friend told me a little story. In the middle of a moonless night she heard strange noises outside her motel window in the Yellowstone National Park in Wyoming. Thinking it might be a thief, she jumped out of bed, opened the door and crept towards a dark shadow. As she got close, she saw the thief. She was dreadfully frightened: it wasn't a human thief ­ it was a big black bear. The bear was turning over some empty tins with its paw, looking for tasty bits of food. My friend decided to leave that particular thief alone!

    There are also, of course, places called "rooming houses", where they receive lodgers (房客). You will see such signs as Tourists or Rooms Rent, and you could try one of these. A word of warning ­ looking for a room in New York during the tourist season is like looking for gold on the moon!
