Question

【題目】Before going outside in the morning, many of us check a window thermometer 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 100 degrees.

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:本文介紹了制作溫度計(jì)的方法。并非所有的溫度計(jì)運(yùn)用同樣的體系，有兩種不同的類型：華氏溫度計(jì)和攝氏溫度計(jì)，但是都用凝固點(diǎn)和沸點(diǎn)作為指導(dǎo)原理，接著解釋了溫度計(jì)的制作方法。

【1】A考查對(duì)上下文的理解和推理判斷能力。由前文This helps us decide what to wear溫度計(jì)幫助我們決定穿衣，后文We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven.知我們?cè)谌粘Ｉ�活中都�?huì)用到溫度計(jì)，A句正好總結(jié)了溫度計(jì)在生活中的廣泛運(yùn)用，故選A。

【2】E考查對(duì)上下文的理解和推理判斷能力。第二段引出了兩種不同的溫度計(jì)，但是它們的工作原理相同，E正好解釋了他們的不同之處，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. 關(guān)鍵信息有凝固點(diǎn)、沸點(diǎn)不同，故選E。

【3】C考查對(duì)上下文的理解和推理判斷能力。分析該空下面的段落提取信息firstly、finally，可知作者在告訴我們?nèi)绾沃谱鳒囟扔?jì)，C正好符合，是一個(gè)總結(jié)句，故選C。

【4】F考查對(duì)上下文的理解和推理判斷能力。聯(lián)系上下文有如下動(dòng)詞：fill、tap、put、stick、place，這都是在教我們?nèi)绾巫鰷囟扔?jì)，本空位于制作環(huán)節(jié)的中間部分，故也是有關(guān)鍵動(dòng)作的，F(xiàn)中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 them together.告訴我們要用蠟把吸管和杯蓋封緊，故選F。

【5】D考查對(duì)上下文的理解和推理判斷能力。本題給出了清晰的提示信息，該空后面As the temperature goes down, the water will contract, and the lever in the straw will come down.知當(dāng)溫度下降，水變少此時(shí)溫度計(jì)的刻度杠桿下降。那么該空對(duì)應(yīng)的就是溫度上升這一情況，D描述了此情況，故選D。
