__12__ using any thermometer, double check that it covers the right temperature 13 for your activity or experiment.
答案：(A) range
temperature range（溫度範圍）是固定搭配，表示溫度計所能偵測的溫度區間。record（紀錄）、system（系統）、unit（單位）都不符合「溫度計涵蓋範圍」的語意。
四個選項都是名詞，都能接在 temperature 後面組成一個名詞組，你會憑中文挑一個。
答對率四成二。關鍵在空格前面的動詞 covers。cover 在這裡是「涵蓋、包含」，它涵蓋得住的必然是一段有寬度的東西，而不是一個點。所以填 range，temperature range 就是「溫度範圍」。填進去讀成 double check that it covers the right temperature range for your activity（再確認一次它涵蓋的溫度範圍適不適合你要做的事）。下一句的例子也能驗算：花園用的溫度計拿去量沸騰的液體會爆掉，正是因為它涵蓋的範圍不夠高。
record（紀錄）指的是記下來的數值，一個紀錄不需要被「涵蓋」；system（系統）在這一篇最後一段確實出現過（different systems of measures 不同的度量系統），形態也吻合，容易被順手選走，但溫度計涵蓋的不是一套系統；unit（單位）是刻度的名稱，公尺、公斤都是單位，是一個點而不是一段。
temperature range（溫度範圍）、cover a range（涵蓋一段範圍）、a wide range of（各式各樣的）、conversion tables（換算表）、unit（單位）、system of measures（度量系統）。
Measurements are needed in many everyday activities. In kitchens you will find measures for volume (measuring cups), mass (scales and weights), and temperature (cooking thermometers). Accurate measurements are 11 important for scientific experiments.
In a laboratory, make sure your measure meets your needs. 12 using any thermometer, double check that it covers the right temperature 13 for your activity or experiment. A garden thermometer, 14, will burst if you try to use it for boiling liquids.
There are different systems of measures. Most scientists now use the International System of measures, with meters for length, kilograms for 15, and seconds for time. If the measures in your experiment show other units, appropriate conversion tables for different systems may prove to be very useful.
