Para. 1
… However, there is increasing evidence that the real driver of poor health is not so much fatty food, as it is sugar. Heart disease is the number one killer of Americans. And in America, people who receive 25% of their daily calories or more through sugar are twice as likely to die from heart disease than people who receive less than 10% a day (Journal of the American Medical Association, 2014). This is true regardless of how healthy the rest of their diet might be…

By showing contrasting ideas and explaining
consuming different categories of fresh foods，especially fruit and vegetables
have some meat，beans，or dairy products in your diet
Para. 3
Beyond this, you can keep healthy by consuming different categories of fresh foods, especially fruit and vegetables, which are full of vitamins and fibre, rather than processed foods. Processed foods often contain less nutrition, and have higher quantities of sugar, salt, and fat than fresh ingredients. Besides this, it is also important to have some meat, beans, or dairy products in your diet, as they provide the necessary protein for strong bones and muscle growth. As with everything in life, moderation is key. The ideal diet is a balanced one, without too much or too little of any one thing.
D．A fundamental key to healthy eating is to eat slowly.
Detail(s)：_________________________________________________
______________________________________________________________________________________________________________________________________________________________________________
People who chew too quickly end up eating too much food because they still feel hungry.
Eating slowly also allows your body to digest your food better，and will allow you to enjoy your food more.
Para. 4
Finally, a fundamental key to healthy eating is to eat slowly. It takes about twenty minutes from the time you start eating for your brain to tell your body that you are full. What this means is that people who chew too quickly end up eating too much food because they still feel hungry. Eating slowly also allows your body to digest your food better, and will allow you to enjoy your food more. In addition, studies show that consistent eating habits, for example, taking three meals a day at the same time each day, are better for our health. It is also better to eat a modest amount of food each time, rather than to eat a lot in one meal, and then a little in the next.
By listing data and giving reasons
E. … healthy eating starts with having a healthy attitude towards food.
Detail(s): ______________________________________________
______________________________________________________________________________________________________________
By explaining, showing contrast ideas and introducing another way of expressing what was already mentioned.
“Do I eat to live, or live to eat ”
It is up to you to decide how you want to live, and to make the right decisions about your diet.
Para. 5
There is no one trick to healthy eating. Rather, healthy eating starts with having a healthy attitude towards food. One question you can ask yourself is, “Do I eat to live, or live to eat ” If you are using food mostly for nutrition, then you are on the right track with your diet. However, if food has become the centre of your life, you might be on the road to bad health. It is up to you to decide how you want to live, and to make the right decisions about your diet.
2．Find the linking words in the passage that introduce another way of saying what was already mentioned in the previous sentence.
Put more simply(简而言之)，while people continue to argue over whether or not fatty food is dangerous，we already know that sugar is a killer.
In other words(换句话说)，if you want to be healthy，you have to cut down on desserts，and cut out sweet drinks altogether.
What this means is that (这意味着) people who chew too quickly end up eating too much food because they still feel hungry.
3．Find the linking words in the passage which show that contrasting ideas are being introduced.
However，there is increasing evidence that the real driver of poor health is not so much fatty food，as it is sugar.
…foods，especially fruit and vegetables，which are full of vitamins and fibre， rather than processed foods.
It is also better to eat a modest amount of food each time，rather than to eat a lot in one meal，and then a little in the next.
There is no one trick to healthy eating. Rather，healthy eating starts with having a healthy attitude towards food.

[参考范文]
Overall，I think I have healthy eating habits. I am eating a variety of healthy and nutritious food on the list，such as fish，eggs，fruit，and salad. Put simply，most of my diet contains food that is good for my body. The fruits and vegetables that I eat are full of vitamins and minerals.
However，I do have some bad eating habits. I sometimes find myself too busy and forget to eat. I am also particular about food，and still eat or drink too much. All these bad habits will do harm to my health. I could prepare some healthy dishes in advance that I can eat when I’m too busy. I should also avoid eating in front of the TV，as it is too easy to eat too much that way.
After reading the article，I now better understand how to eat more healthily and improve my food choices. I hope to follow a balanced diet to build up a strong body. It is up to me to make the right decisions about my diet，and I have decided to be healthier and happier！

Homework
Dear Mike,
Learning that you don’t like eating fresh vegetables, eggs, coarse grains and even dislike drinking milk, I am concerned about your health and would like to share some suggestions with you.
To be honest, you’d better attach great importance to keeping a balanced diet, which is of great importance to your body and study. It is widely believed that fresh vegetables and milk contain plenty of minerals as well as vitamins we need. Besides, proteins, which we mainly get from eggs and beans, play a vital important role in building up a strong body.
Wish you good health and great progress in your lessons!
Yours,
Li Hua
