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._____72_______ .
the most common kind of thermometer is made with mercury(水銀)inside a clear glass tube. as mercury (or any other liquid ) becomes hot, it expands. as it gets colder, it contracts(收縮). that is why on hot days the mercury line is high in the glass tube.______73______.
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.
_______74____________.
finally. place a white card on the outside of the bottle and behind the straw. now you can see the water lever easily.
_______75___________.
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.

choosing the right job is probably one of the most important decisions we have to make in life, and it is frequently one of the hardest decisions we have to make. one important question that you might ask yourself is: “how do i get a good job?”___71___.
there are people who can answer an insignificant advertisement in the local paper and land the best job in the world; others write to all sorts of places all over the country, and never seem to get a reply at all. still others believe that the in person, door-to-door approach is by far the best way to get a job; and then there are those who, through no active decision of their own, just seem to be in the right place at the right time. ___72____.he used to spend a lot of his free time down by the sea watching the tall ships, but never thinking that he might one day sail one of them. his father was a farmer, and being a sailor could never be anything for the boy but an idle dream. one day, on his usual wandering, he heard the captain of the ship complaining that he could not sail because one member of his crew was sick. without stopping to think, the lad（少年）offered to take his place. ___73___.
