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.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.

A

My daughter Kelly is a cautious person.She needs to warm up to situations,is hesitant to try new things.When with close friends,she becomes a leader who laughs loudly and chants,“Girls rule,boys drool.” But when that comfort zone is not around her,she is shy and nervous.

This has been challenging for me at times.“Shy” is not a word that I think has ever been used to describe me.But this has been a year of firsts for my girl that has filled her with a new sense of confidence.This year she moved to lap lane in swimming where she was preparing for a swim team.This year she learned to ride a bike without training wheels.And this year she completed her first kids’ triathlon (三项全能) .

On Saturday,with a thunderstorm coming soon and my son’s birthday party later in the day,we all went out in the dark of the morning for Kelly to participate in her first triathlon.We practiced transitions from swim to bike to run with her,we got all the equipment she’d need,and we kept talking about the race.But as we waited the two hours for the older kids to finish before her turn,she held my leg a little harder and told me she loved me a few too many times.She was nervous but trying to keep it together.

And then it was her turn.From the second she jumped into the water,my heart soared. My daughter transformed into the most confident human being I had ever seen.She dominated(主宰) that swim,crushed that bike ride and ran to the finish with the biggest smile on her face.

I can honestly say that I never felt so proud of someone in my entire life.It wasn’t because she did a sport or anything like that.It was because she was afraid of something and conquered(克服) that fear with confidence and a fire I hadn’t seen before.

All day I would find myself just looking over at her and smiling.She might be wearing the finalist medal but I felt like I won that day.I won the chance to see my girl shine.

Shine on,sweet baby.
