問題詳情
V. 閱讀測驗 (10分，每題2分)Science is in our everyday lives, even in cooking. Understanding the science of food can help you cook a meal or prepare a snack.For instance, you might know that cutting an onion (洋蔥) can make you cry. That is because cutting the onion makes chemicals inside it mix and form (產生) acid (酸). This can be prevented by keeping the onion in the refrigerator, or by cutting it under water. You might also know that if you cut certain kinds of fruits, such as apples and pears, they turn brown very quickly. This happens because these fruits contain a chemical that reacts (反應) with oxygen (氧氣). One way to prevent this is by adding some lemon or tangerine juice. The acid in the juice prevents the chemical reaction.Whether you are preparing a snack or learning how to cook, science is a part of what you do. In fact, you might say that to be a cook, you must also be a scientist!
