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. 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 level easily.
________5.________
As the temperature goes down, the water will contract, and the level in the straw will come down. Perhaps you will want to keep a record of the water level in the straw each morning for a week.
A.Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled.
B.We use and depend on thermometers to measure the temperature of many other things in our daily lives.
C.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.
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 100 degrees.
F.Now that you know this rule you can make a thermometer of your own that will work.
G.People use thermometers which are made by themselves when travelling around the world.

高三英语七选五中等难度题查看答案及解析
For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.
In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.
However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.
“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls,” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, selfharm, low concentration and poor performance at school,” she added.
While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.
Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.
1.According to the passage, we can know ________.
A.it's a good habit to play with smartphones or iPads late into night
B.scientists suggest we should avoid using smartphones or iPads
C.darkness makes a great impact on the amount of melatonin
D.the sun was the only source of light in ancient times
the sun was the main source of light.”可知D项为错误结论。
2.Which of the following is TRUE according to the passage?
A.The darker it is, the more melatonin will be produced.
B.The lighter it is, the more melatonin will be produced.
C.The more melatonin you have, the worse you'll sleep.
D.The more electrical equipment you have, the more melatonin will be produced.
3.The underlined part in Paragraph 4 refers to those ________.
A.who are young adults or adolescents
B.who don't perform well in school
C.who are addicted to a television or laptop
D.who are short of sleep at night and perform poorly in daily life
4.In the writer's opinion, which is a correct suggestion?
A.You should go to bed when the sun goes down.
B.You should use an orange or red light electronic screen.
C.You should wear a pair of blue sunglasses when sleeping.
D.You should avoid blue light as possible as you can before bedtime.
