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.

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.

Between their crazy schedules and upside-down circadian（昼夜节律的） rhythms, teens have always been somewhat sleep-deprived（剥夺）．Now technology is making it worse．
Teens are not just texting, instant-messaging and surfing Facebook all day; they’re sleeping with their cell phones or laptops, too．Or rather, not sleeping．And doctors and parents, many of whom raised in an era when phones were attached to walls, are concerned．
“So many teens are having sleep issues, and parents aren’t necessarily regulating the use of the electronic devices enough,” says Margie Ryerson, a therapist．“It’s impossible to wind down and relax the body, the mind, the senses and be ready to fall asleep．”
“We all know teens don’t get enough sleep in general,” says San Francisco．“As long as parents allow teens to have these devices in their bedrooms at night, teens will be tempted（诱惑） to use them．”… Teens would socialize 24/7 if they could．
Ryerson calls it the CNN syndrome of teenhood— round-the-clock reports on breaking news about everything, from homework to wardrobe choices to ice-cream cravings．
Sleep deprivation is linked to memory and concentration problems, anxiety and depression, and moodiness．“Many people assume these problems arise directly from adolescence, which is not really true,” he says．“The real issue is sleep deprivation．Late-night texting can certainly make the situation worse．”
“The psychology behind this constant contact is certainly understandable,” Ryerson says．“It comes from wanting to avoid being left out．They won’t be considered important and significant in their peer group, if they don’t know what’s going on．If they’re on top of everything, they belong,” she says．
“What helps, at least for younger kids,” says Ryerson, “is parental involvement．If all of their friends are all able to text into the early hours of the night, it is hard for a middle or high schooler to set the limit themselves．Often they appreciate parents stepping in．”
“As parents, we want our kids to be happy, healthy and responsible,” she says, “and the most necessary requirement for achieving balance is to first take care of ourselves physically — eating well, exercising and getting enough sleep．”
【小题1】According to Ryerson, it seems that ____．
