Improve Your Eating Habits
改善你的饮食习惯
Healthy eating is important for a healthy body and mind. Both what we eat and how we eat are important!
健康饮食对身心健康很重要。我们吃什么和怎么吃都很重要！
body and mind

Both what we eat and how we eat are important.（我们吃什么和怎么吃都很重要。）both ... and ... 连接两个并列成分，谓语用复数。
For example, some people have fast food every week. It is easy and delicious! But it often has lots of salt, fat, and sugar. That makes us put on weight. Eating fast food like pizza and hamburgers too often may cause heart problems later. If you cook your own meals instead, you can make healthy balanced meals.
例如，有些人每周吃快餐。它方便又可口！但快餐通常含有大量的盐、脂肪和糖，那会使我们体重增加。过于频繁地吃比萨和汉堡等快餐，以后可能会引发心脏问题。如果你改为自己做饭，就能做出健康均衡的餐食。

if 条件句 + 情态动词 can
If you cook ... , you can make ...（如果你做饭，你就能做出……）if 条件句中用一般现在时，主句用情态动词 can。
Eating three meals a day is important. But some people don't have breakfast. Maybe they don't feel hungry in the morning, or they are too busy to eat anything. But food gives us energy. If we don't eat breakfast, it is easy to feel sleepy. It is also hard to focus on our work or studies.
一日三餐很重要。但是有些人不吃早餐。也许他们早上不觉得饿，或者过于忙碌而没有进食。但是食物给我们能量。如果我们不吃早餐，就容易感到困倦，也难以专心工作或学习。

too ... to 结构
too busy to eat anything：太忙了以至于不能吃东西。too + 形容词 + to do = 太……而不能……。= so ... that ... can't ...
It is + adj + to do
It is easy to feel sleepy.（容易感到困倦。）It is + 形容词 + to do，It是形式主语，真正主语是后面的不定式。同样：It is hard to focus.
Some people also eat too many sweet things. Ice cream, sweets, and chocolate are delicious, but they usually have lots of sugar. This can cause tooth problems. When you want a snack, why don't you have some fruit instead? After all, an apple a day keeps the doctor away.
有些人还吃太多甜的东西。冰激凌、糖果和巧克力很好吃，但它们通常含有大量的糖。这会导致牙齿问题。当你想吃点心的时候，为什么不改吃些水果呢？毕竟，一天一个苹果，医生远离我。

Why don't you ...? 提建议
