When it comes to food products, it is always important to check the expiration date before you eat or drink. In the United States, every food product is required by law to have an expiration date written on its packaging . There was even once an expiration date printed on bottled water. However, the law requiring this later changed, but the questions still remain: Can water expire? Isn’t water always safe to drink?
While there is no technical expiration date for water, the issue of it being unsafe to drink stems from its method of storage. If stored properly in a sanitized container, tap water normally can be kept for up to six months. The situation of water stored in plastic bottles might differ a little, though. It is necessary to refer to the label and not drink it beyond its expiration date. This is because the plastic can leak into the water and contaminate it with chemicals. If one regularly consumes plastic-polluted water, it can impact one’s well-being by harming gut health, immunity, and respiratory functions.
In order to prevent any bacterial growth or chemical buildup in plastic water bottles,it is best to keep them out of warm places that get a lot of sunlight. Heat allows bacteria to grow and chemicals to escape into the water. Placing water bottles out of direct sunlight in a cool area is a healthy storage technique. Plastic bottles are also permeable, meaning substances from the outside are able to go through the plastic. With this piece of information in mind, it is safer to store water away from cleaning supplies and other chemical products.If the water has developed a strange look, taste, or smell, you should either boil it before drinking or discard it.

(B) Bottled water causes damage to humans’ health, as does tap water. (C) Water that tastes strange is best discarded. (D) It’s best to use plastic bottles because some nutrients can go through them. |
2. What is the second paragraph mainly about? (A) Why water stored in plastic bottles is better than tap water. (B) Why tap water and bottled water are not always safe to drink. (C) Why drinking tap water is more likely to cause health problems. (D) Why there aren’t expiration dates on the packaging of bottled water. |
3. Danny bought a carton of bottled water for emergencies. Which of the following is the best way for him to store the water? (A) Place the carton in a warm spot to prevent harmful chemicals from building up. (B) Put the carton in the location where household cleaners are stored.

什麼!水有壽命!?
談到食品,在吃或喝之前檢查到期日一直都是很重要 的事情。在美國,法律要求每項食品的包裝上都要寫出到期 日。甚至有一度得把到期日印在瓶裝水上。然而,要求這一 點的法律後來發生了變化,但問題仍然存在:水有可能過期 嗎?水不是永遠都可以安全飲用嗎?
雖然水沒有嚴格的到期日,但水無法安全飲用的問題源 於其貯存的方式。如果自來水妥善貯存在消毒過的容器中, 通常可以保存長達六個月。不過,貯存在塑膠瓶的水情況可 能有點不一樣。一定要查看標籤,而且不要在過期後飲用。 這是因為塑膠會滲入水中,且其化學物質會汙染水。如果一 個人經常飲用受塑膠汙染的水,它會損害腸道健康、免疫力 和呼吸功能,從而影響一個人的健康。
為了防止塑膠瓶中任何細菌的生長或化學物質的堆積, 最好讓塑膠瓶遠離陽光充足的溫暖區域。熱度使細菌生長, 也會讓化學物質滲入水中。將水瓶放在避免陽光直射的陰涼 處是一種適切的貯存方式。塑膠瓶也是可滲透的,這意味著 來自外部的物質能夠穿過塑膠。有鑑於這項資訊,把水貯存 在遠離清潔用品和其他化學產品的地方會更安全。如果水的 外觀、味道或氣味變得很怪,那你應該在飲用前將其煮沸或 直接丟棄。

2. 下列何者為第二段的主旨? (A) 為什麼貯存在塑膠瓶中的水比自來水好。 (B) 為什麼自來水和瓶裝水並非永遠可以安全飲用。 (C) 為什麼喝自來水更容易引起健康問題。 (D) 為什麼瓶裝水的包裝上沒有到期日。 |
3. 丹尼買了一箱瓶裝水以備不時之需。以下哪項是他貯 存這些水的最佳方式? (A) 將其放在溫暖的地方,以防有害化學物質堆積。 (B) 將其放在存放家用清潔劑的地方。 (C) 將水貯存在陽光充足的地方以殺死細菌。 (D) 將水放在涼爽的地方。 |
