1. Choosing what to eat is no longer as easy as it once was.
我們在選擇吃的東西方面，現在不像過去一樣簡單了。
[問]as在此處作何解釋?
[答]作連詞，表示比較。又如：My hometown is no longer the same as it was. 我的家鄉同過去不一樣了。
2. if we want to keep up with the high pace of modern life, we had better learn to make the right choices about what and how we eat. 如果我們要跟上現代生活的步伐，我們最好學會正確的選擇吃什麼以及怎麼吃。
[問]如何分析此句?
[答]這裏if引導的是條件狀語從句，we had better ...是主句，what and how we eat 是賓語從句做about的賓語。keep up with 趕上，跟上，had better最好。
3. When we choose what to buy and eat, we had better think if the food will give us the nutrients we need. 當我們選擇我們想要買和想要吃東西的時候，我們最好想一想這些食物是否提供了我們所需要的 營養。
[問]這個句子中有三個從句，對嗎?
[答]對。when...， 是時間狀語從句;if...是賓語從句;we need是定語從句。
4. Some nutrients help build our body and amke it stronger. 一些食物有助於我們增強體魄。
[問]build our body and make it stronger 一起做help的賓語嗎?
[答]是的。
5. Caicium, which is found in eggs, milk and other dairy products, is good for our bones and teeth.
[問]which is found in eggs, milk and other dairy product 是定語從句嗎?
[答]是的。而且引導詞which在從句中作主語，代替calcium。
6. Other nutrients help keep our body functioning well. 其他的營養物有助於我們的身體正常運轉。
[問]function在這裏作動詞嗎?
[答]是的。在這裏“起作用”等的意思。
7. But the choices we make are not just about nutrion. 但是，我們做出的選擇不僅是營養方面的。
[問]we make 又是定語從句?
[答]是的。make choices 是“作出選擇”的意思。引導詞which/that 作賓語，可以省去。
8. Eating habits become part of who we are: people become vegetarians either because they believe it is healthier not to eat meat or because they so not think we should kill animals for food.
飲食習慣成了我們信仰中不可分割的部分;素食主義者有的認爲不吃肉身體要更健康些，有的則是不主張殺動物爲食者。
[問]這麼長的句子，怎麼分析?
[答]主句是：Eating habits become part of who we are. Eather..., or... 引導兩個because 原因狀語從句。
9. We also make choices based on how the products are grown or made: environmentally friendly foods, or "eco-foods", are made by companies who have tried to use green and clean ways to make the foods. 我們對產品的作出的選擇還決定於生產和加工方式，要是環保性的或者說是生態性的食物，是廠家用綠色而又清潔的方式生產出來的食物。
[問]此句是否定語從句中套定語從句。
[答]對。that are grown without chemicals 做vegetables 的定語;that can be harmful to human beings and the environment 做chemicals 的定語。
11. If our diet includes foods from all the food groups, in the right amounts, we so not have to buy any supplements. 如果我們食物品種多，數量恰當，我們就不需要買任何補給品。
[問]請解釋此句中的if結構和do not have to 相當與need't。
12. The same goes for "crash diets" that some companies say will make us lose weight fast. 對於一些公司所宣稱可以讓我們減肥的減肥餐也如此。
[問]that some companies say will make us lose weight fast 起什麼作用?
[答]定語從句。that 在從句中作主語代替“crash diets"。
13. Instead of eating expensive diet foods or going on unhealthy diets, we can simply try to eat less fat and sugar and exercise more. 我們不需要去吃那些昂貴的固定飲食或者不健康的飲食， 只需要少吃脂肪和糖， 多鍛鍊就行了。
[問]請問intead of 介詞短語?
[答]instead of 是介詞短語， 表示“代替”的意思。
14. The best way to make sure that we will feel and look fine is to develop healthy eating habits. 保健的最好方式是養成健康的飲食習慣。
[問]這句話的主句究竟是什麼?
[答]The best way is to develop healthy eating habits 是這句話的主句 to make sure that we will feel and look fine 不定式短語做定語， 修飾the best way.
15. We ought to learn more about our body and the fuel it needs so that we can make sure that we are well prepared for the challenges and opportunities in life.
我們應該更多地瞭解自己的身體以及我們身體所需的養料， 以便我們對生活中所面臨的機遇和挑戰有充分的準備。
[問]so that 是什麼意思?
[答]so that 是“以便”的意思，常引導結果狀語從句。
16. That means that sandwich or a salad is a good choice, but a chocolate bar or a bag of patato chips is not. 也就是說，要選擇三明治和色拉之類的而不是選擇巧克力和炸土豆條。
[問]如何分析此句句子 成分?
[答]“That" 是主語， “mean" 是謂語， 後面整個that引導的兩個並列從句是賓語，第二個從句“is not" 後省略了a good choice.
