考量食物的種類及烹煮
Almost everyone has eaten leftovers despite having heard about their health risks.
幾乎所有人都吃過剩菜，也明白吃剩菜產生的健康風險，
almost幾乎=nearlydespite儘管+n.=in spite of、despite the fact that=in spite of the fact that+子句risk(n.)風險、risky(adj.)危險的、take a risk冒風險、at risk處境危險
Even the Food and Drug Administration (FDA) advises people to either eat or throw away food four days after its preparation.
連美國食品暨藥物管理局（FDA）也建議剩菜最好在4天內就要食用完畢。
FDA食藥署drug(n.)藥品、毒品、drugstore藥妝店advise(v.)建議+to、強烈忠告警告意味、suggest(v.)建議、語氣較和緩、recommend(v.)建議、推薦、強調好處throw away=get rid of=discard丟棄preparation(n.)準備、prepare(v.)準備

他們建議考量食物的種類以及它們烹煮、保存的方法才是決定期限的關鍵。
suggest建議item物品store(v.)儲放、保存、被動態make decision做出決定
Crosby notes that pH levels and moisture content are the major considerations.
他指出要留心一些條件，
pH level酸鹼值moisture(n.)濕氣、水分consideration(n.)考量、consider(v.)考量
Foods with lower pH levels, such as ketchup, typically last longer– up to one week.
如食物的酸鹼值以及含水量。較酸的食物，像是番茄醬，通常能放比較久，可以長達一周，
low(adj.)低、high(adj.)高such as=for example比方說ketchup番茄醬
typically通常=usuallylast(v.)保持、持續up to高達、長達
That’s because the acid in them is more likely to check the growth of bacteria.
因為所含的酸能夠抑制細菌生長。
acid酸、acid rain酸雨be likely to有可能check the growth抑制生長bacteria、bacterium(n.)細菌、前者為複數、bacterial(adj)細菌的
On the other hand, leftovers with higher pH levels, such as fish and eggs, should be eaten as soon as possible or discarded after three days because they tend to favor bacterial growth.
另外，低酸食物如魚肉、蛋類則最好盡快吃完，或三天後就要丟棄，因為比較容易滋生細菌。
on the other hand另外一方面as soon as possible越早越好
discard(v.)丟棄tend to傾向、易於+RVfavor支持、有利於、in favor贊同
What’s more, foods with high moisture levels, such as meat and vegetables, should also be eaten within three days, even when they are stored in the fridge.
此外，含水量高的食物如肉類和蔬菜，就算放在冰箱內也只能放最多三天。
what’s more=moreover=in addition更甚者、再來fridge(n.)冰箱、freezer(n.)冰庫
Crosby recommends storing your leftovers in the freezer if you want to eat them after one week or longer.
克羅斯比建議，如果你要在一周或是更長的時間後才要吃剩菜，必須將其保存在冷凍庫內，
recommend(v.)推薦、recommendation(n.)推薦
Adding vinegar or lemon juice also helps to preserve the food, he says.
添加醋或是檸檬汁也可避免食物腐壞。
helps單數、動名詞當主詞vinegar醋preserve(v., n.)保留、貯存、野生動物保護區、果醬
