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.__1.__. 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.__2.__.
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.__3.__.
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.____4.____.
Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily. ____5.____.
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.People use thermometers which are made by themselves when travelling around the world. |
B.We use and depend on thermometers to measure the temperature of many other things in our daily lives. |
C.Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled. |
D.Now that you know this rule you can make a thermometer of your own that will work. |
E.The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher.
F.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.
G.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.
With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills(泄露) on people, nature, and the environment.
Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil.Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.
Of all of today’s environmental disasters, an oil spill may actually be one of the least serious.Although oil is poisonous, it is a natural material.In the end, it breaks down naturally.There are, of course, long-term effects, but it is usually more serious in the short term.
Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible.In 1967 the tanker Torrey Canyon sank off the Sicily Isles near the coast of England and spilled 120,000 tones of oil into the ocean.If you go there today, you will find it hard to see any sign that it ever happened.
Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage.Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!
We should be thinking more about reducing our dependency on oil.Governments should be encouraging research into new technologies, such as cars run by solar power(太阳能), electricity, hydrogen, and so on.Much of this research has, in the past, been held back by the oil, gas, and coal.
If the world’s millions of cars were 10% more efficient(高效的)— and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year.If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.

When you cough or sneeze, you’d better turn your head away from others and cover your mouth with the full part of your hand. And then, you should say, “Excuse me.”
This seems so simple, but it is surprising how many kids have never been told to do this. Actually, I notice adults all the time who cough and sneeze in public without placing a hand over the mouth. One important thing I point out to the kids is that after they sneeze or cough on their hands, they should wash their hands as soon as possible. If not, they will be passing those germs (细菌) along to everything and everyone they touch.
If you come to a door and someone is following you, hold the door. If the door opens by pulling, pull it open, stand to the side, and allow the other person to pass through first, then you can walk through. If the door opens by pushing, hold the door after you pass through.
After a few weeks of seeing kids try to get through doors in the school and watching them enter restaurants as the door hit other people, I knew I had to discuss the problem with my students. Teaching them small acts of kindness, such as letting someone else go through a door first as they hold it open, may seem unimportant, but it can go along way toward helping students realize hot to be polite and thank others. Once they’ve been told, they’re halfway there.
When we have to go up moving stairs, we will stand to the right. That will give others who are in a hurry a choice of walking up the left-hand side of the moving stairs. When we are going to enter a lift, the underground, or a doorway, we will wait for others to exit before we enter.
After college when I moved to London, I was surprised at how polite everyone was in the subways. I was even more touched when I traveled to Japan. In both places, people made efforts to make way for others. On moving stairs, everyone stood to the right and walked to the left. On lifts, everyone would stand over to the side and allow others to exit before they would begin to enter.
1.When you cough or sneeze, you should ________.
A. touch everything B. cover your mouth
C. point out to the kids D. pass the germs to others

I know what you’re thinking : pizza (比萨饼)? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to.
I know lots of women who skip(跳过) breakfast , and they have a ton of different excuses for doing it . Some say they don’t have time. others think they’re “saving” calories (卡路里), still others just don’t like breakfast food .
But the bottom line is that eating in the morning is very important when you’re trying to lose weight.
“Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking , R , D , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
1.The word “leftovers” in Paragraph 1 probably means__________.
A. food remaining after a meal B. things left undone
C. meals made of vegetables D. pizza topped with fruit
2.What can we infer from the text?

B. Many people have wrong ideas about breakfast.
C. There are some easy ways of cooking a meal.
D. Eating vegetables helps save energy.
3.According to the last paragraph, it is important to____________.
A. eat something for breakfast B. be careful about what you eat
C. heat up food before eating it D. eat calorie-controlled food
4.The text is written mainly for those_____________.
