Unit 4 Cyberspace(B)(对应学生用书第247页)Ⅰ.阅读理解(2017·河北石家庄高三复习教学质量检测(二))It's cold and dark outside, and your bed is so warm and comfortable.Going for a run seems like such a bad idea.But before you hide your running shoes, it might be worth giving that crazy idea ago.According to The Huffington Post, an outdoor run in winter, as opposed to one on a treadmill (跑步机), burns more calories because the body is working hard to regulate (调节) its core temperature.Furthermore, research shows that race times are faster in cold weather than in warmer temperatures－and quicker runs burn more calories.Similarly, cold weather also makes the heart work harder to distribute blood through the body, making that vital muscle even stronger.Outdoor exercise also turns up your energy and rids you of the stress and depression that build up every day.The heat and humidity in summer can drag you down and tire you faster, but cold weather is refreshing.It adjusts you to your surroundings, making you feel alive.Of course, the threat of smog in some built­up areas is a further hurdle to winter exercise.Heart attacks, strokes, lung cancer and asthma are all dangers of running in smog.The combination of air pollution and exercise increases the potential problems.If you do choose to run outside on smoggy days, take a path in a park or residential area to avoid car exhaust (废气) ，and go early in the morning, before rush hour.But staying inside on smoggy days and waiting for the next clear day to run is best.【语篇解读】本文是一篇说明文。

]Ⅱ.阅读七选五(2017·湖南十三校第一次联考)Every culture has its own unwritten list ofbehavior that is acceptable.Every society also has its taboos, or types of behavior that are considered a violation of good manners.The word taboo comes from the Tongan language and is used in modern English to describe verbal and nonverbal behavior that is forbidden or to be avoided. 1 They tend to be specific to a culture or country, and usually form around a group's values and beliefs.What is considered acceptable behavior in one country may be a serious taboo in another.Verbal taboos usually involve topics that people believe are too private to talk about publicly, or relate to one's manner of speaking.In many cultures, for example, it is considered bad manners to discuss subjects such as sex or religion in public.In some countries, too much volume of one's voice may annoy people. 23 For example, one of the biggest differences among many Western, Asian, and African cultures is the use of eye contact.In the U．S., people make eye contact when they talk to others.4 In many Asian and African cultures, however, children are taught to lower their eyes when talking to their elders, or those of higher rank, as a way to show respect.Certain gestures made with the hands can have very different meanings depending on the country you are in.Crossing your middle finger over your forefinger is the sign for good luck in many western countries. 5 Also, in some Asian countries, moving your hands a lot while talking, or “talking with your ha nds”，is considered unsuitable.Behavior that is acceptable and non­offensive in one culture can be highly offensive in another.When visiting a foreign country, be aware of some of the basic differences, as this will help to ensure a more enjoyable trip.A．Nonverbal taboos usually relate to body language.B．In Vietnam and Argentina, however, it is a rude gesture.C．In spite of what some people may think, taboos are not universal.D．Cancer is a taboo subject and people are frightened to talk openly about it.E．Learn a country's customs so that you don't hurt the local people unconsciously.F．They might think that someone who is speaking or laughing loudly is rudeor aggressive.G．If a person avoids eye contact, others might think they are being dishonest or unconfident.【语篇解读】本文主要讲述了不同国家习俗方面的禁忌，以及肢体语言、手势语的不同运用。
