Question

【題目】根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

Before going outside in the morning, many of us check a window thermometer(溫度計(jì))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.____ 【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.

Answer 1

【答案】

【1】A

【2】E

【3】C

【4】F

【5】D

【解析】

試題分析：我們的日常生活離不開溫度計(jì)，我們用它來(lái)了解氣溫，測(cè)量體溫等。溫度計(jì)的工作原理是水銀的熱脹冷縮，溫度計(jì)的制作過(guò)程比較容易

【1】A根據(jù)“check a window thermometer(溫度計(jì))for the temperature”可知，本段與溫度計(jì)和溫度有關(guān)，空白處后面舉了日常用到溫度計(jì)的幾個(gè)例子，A項(xiàng)“日常生活中，我們使用并依靠溫度計(jì)來(lái)測(cè)量溫度”符合段意，故選A。

【2】E根據(jù)前一句“Both systems use the freezing and boiling points of water as their guide.”可知，本段講的是華氏溫度和攝氏溫度的計(jì)量方法，E項(xiàng)講的是各自冰點(diǎn)和沸點(diǎn)的標(biāo)示方法，與段意相符，故選E。

【3】C 根據(jù)“As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收縮).”可知，本段講的是溫度計(jì)的原理，C項(xiàng)“既然了解了溫度計(jì)的工作原理，你可以自己動(dòng)手制作溫度計(jì)了”，與段落聯(lián)系最緊密，可知選C項(xiàng)。

【4】F從第五段開始，講的是制作溫度計(jì)的步驟，根據(jù)“Then stick a plastic straw(吸管) through the nail hole.”可知，接下來(lái)需要把吸管和瓶蓋粘在一起，F(xiàn)項(xiàng)“把蠟或蠟燭熔化，把縫隙粘住”符合上下文的聯(lián)系，故選F

【5】D 根據(jù)As the temperature goes down, the water will contract, and the lever in the straw will come down可知本段講的是制作完成的溫度計(jì)隨著氣溫的升降而出現(xiàn)的現(xiàn)象，空白處講的是溫度上升時(shí)候的現(xiàn)象，故選D
