Before going outside in the morning, many of us check a window thermometer(温度计)for the temperature. This helps us decide what to wear. _____76____. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.
Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.
Both systems use the freezing and boiling points of water as their guide._____77_____ .
The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube._____78______.
First. Take a clear glass juice bottle that has a cap ; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.
______79______.
Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.
______80____.
As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.
|
A．We use and depend on thermometers to measure the temperature of many other things in our daily lives. |
|
B．Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled. |
|
C．Now that you know this rule you can make a thermometer of your own that will work. |
|
D．The water will rise in the straw. As the temperature of the air goes up, the water will |
expand and rise even higher.
E．They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.
F．Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal把..粘住) them together.
G．People use thermometers which are made by themselves when travelling around the
world.

Continuing from the previous post 6 reasons to improve your body language, here is just a few of many pointers on how to improve your body language. Improving your body language can make a big difference in your people skills, attractiveness and general mood.
There is no specific advice on how to use your body language. What you do might be interpreted in several ways, depending on the setting and who you are talking to. You’ll probably want to use your body language differently when talking to your boss compared to when you talk to a girl/guy you’re interested in. These are some common interpretations（解释，诠释） of body language and often more effective ways to communicate with your body.
First, to change your body language you must be aware of your body language. Notice how you sit, how you stand, how you use you hands and legs, what you do while talking to someone.
You might want to practice in front of a mirror. Yeah, it might seem silly but no one is watching you. This will give you good feedback on how you look to other people and give you an opportunity to practise a bit before going out into the world.
Another tip is to close your eyes and visualize how you would stand and sit to feel confident, open and relaxed or whatever you want to communicate. See yourself move like that version of yourself. Then try it out. You can also take bits and pieces you like from different people. Try using what you can learn from them.
According to the passage, the improved body language can ______.
make people charming

D
Will it matter if you don’t take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains, if a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class. Contrary to what many people believe, if you don’t eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
77. The results of the test show that ______
A. breakfast has great effect on work and studies.
B. breakfast has much to do with people’s health.
C. a person will work better if he has simple breakfast
D. breakfast only affects those who work with their brains.
78. The passage mentions that many people believe that if you don’t eat breakfast, you will____.
A. not lose weight B. be healthier
C. gain weight D. lose weight
79. We can infer from the passage that _____
A. one can work better without breakfast.
B. morning diet will do good to your health.
C. reducing lunch and supper will help lose weight.
D. breakfast is more important than lunch and supper.
80. What is the best title for this passage?

People who are outdoors in cold weather should avoid actions like suddenly lifting a heavy basket full of snow. Even walking through heavy, wet snow can strain a person’s heart.
Many people aren’t conditioned to the physical stress of outdoor activities and don’t know the dangers of being outdoors in cold weather. Those who like winter sports can suffer accidental hypothermia if they don’t make certain preparations.
Hypothermia means the body temperature has fallen below normal. It occurs when your body can’t produce enough energy to keep the internal (内部的) body temperature warm enough. It can kill you. Heart failure causes most deaths in hypothermia.
Children, the elderly and those with heart disease are at special risk. As people age, their ability to keep a normal internal body temperature often decreases. Elderly people can suffer hypothermia without knowing they’re in danger because they can’t notice the cold conditions as quickly as the young.
Besides cold temperatures, high winds, snow and rain can also steal body heat. Wind is especially dangerous because it removes the layer of heated air from around your body. At 30 degrees Fahrenheit in a 20-mile-per-hour wind, the cooling effect is equal to calm air at four degrees. Similarly dampness (湿气) causes the body to lose heat faster than it would at the same temperature in drier conditions.
To keep warm, wear more clothes. This traps air between layers. Also, wear a hat or head scarf. Much of your body’s heat can be lost through your head. Keep your hands and feet warm, too, as they tend to lose heat rapidly.
Don’t drink alcohol before going outdoors or when outside. Alcohol makes you feel warm at first because blood vessels in the skin expand. But heat is then drawn away from the body’s important organs.
【小题1】The underlined word “strain” in Paragraph 1 means ________.
| A．injure | B．warm | C．control | D．burn |
| A．It means the body temperature falls rapidly. | B．Most heart attacks are caused by it. |
| C．It is not as scary as people think. | D．It can threaten a person’s life. |
| A．they like exercising outside in cold mornings |
| B．they can’t notice cold conditions if they are not told |
| C．their body temperature is generally lower than young people’s |
| D．their ability to keep a normal internal body temperature is not so good |
| A．What causes the body to lose heat faster. | B．The advantages of drier conditions. |
| C．What else can steal body heat. | D．Dangers of high winds. |
| A．Feeling warm at first | B．The body’s heat is taken away |
| C．Blood vessels in the skin expand | D．The risk of hypothermia is reduced |

To get an extra 14 years of life, don’t smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount. That is according to a study published this Monday in the Public Library of Science Medicine Journal.
After tracking more than 20,000 people aged 45-79 years in the United Kingdom from about 1993-2007, Kay-Tee, Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived an average of 14 years longer than those who didn’t.
“We’ve known for a long time that these behaviors are good things to do, but we’ve not seen this benefit before, ” said Susan Jebb, head of Nutrition and Health at Britain’s Medical Research Council. “The benefit was also seen regardless of whether or not people were fat and what social class they came from.”
Study participants（参与者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．
“We can't say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what's theoretically（理论上地）possible．”
“Most people know that things like a good diet matter and that smoking isn't good for them, ”Susan Jebb said．“We need to work on providing people with much more practical support to help them change．”
【小题1】Which of the following DOESN'T belong to the four healthy habits?
| A．Eat five servings of fruits and vegetables a day． |
| B．Do proper exercise in the morning every day． |
| C．Drinking alcohol in the proper amount every day． |
| D．Having a cigarette before going to bed every day． |
| A．Susan Jebb did not take part in the study． |
| B．the study observed people as well as tested specific changes． |
| C．there's no need for people under 45 to adopt these good habits． |
| D．only those from first class can benefit from these healthy behaviors． |
| A．All the people are well aware of the harm of their bad habits． |
| B．People aged 45 to 70 have bad habits in the United Kingdom． |
| C．Governments should take measures to help people change their bad habits． |
| D．People have adopted the four healthy habits after knowing they're good． |
| A．Smoking and Drinking Cuts You 14 Years |
| B．How to Live a Much Healthier Life |
| C．Healthy Habits May Give Extra 14 Years |
| D．How to Make Your Life Longer Than Others |
