Sometimes people are not clear about what kind of food is healthy, and what kind of food may do harm to our health. The USDA has prepared a food guide to help people learn about which kind of food is the healthiest to eat. The food guide describes six main food groups: meat (like fish and chicken), dairy (like milk and cheese),grains (like bread and rice), fruit and vegetables. The last group is fats and sweets. The USDA also suggests how much of each food group is healthy to eat daily. Though this guide was prepared by the US government, it is very useful for people all over the world.
As a result of years of study, we know that too much animal fat is bad for our health. For example, Americans eat a lot of meat and only a small amount of grains, fruit and vegetables. Because of the way they eat, they have a high rate of cancer and heart disease. In Japan, people eat large amounts of grains and very little meat. The Japanese also have a very low rate of cancer and heart disease. The Japanese live longer than anyone else in the world. However, when Japanese people move to the US, the rate of heart disease and cancer goes up as their eating habit changes. And as hamburgers, ice creams and other high-fat foods become popular in Japan, the rate of heart disease and cancer is going up there as well. People are also eating more meat and dairy food in other countries, in which the disease rate is going up along with the change of the way people eat. Doctors everywhere suggest people eat more grains, fruit and vegetables and less meat and dairy food.
Eating healthily is important for children as well as their parents. When parents have poor eating habits, their children usually do, too. After all, children eat in the same way as their parents. When parents eat healthy food, the children will learn to enjoy it, too. Then they will develop good eating habits. Doctors suggest parents give their children healthier food such as fruit, vegetables and juice.
Everyone wants to live a long, healthy life. We know that the food we eat affects us in different ways. For example, doctors believe that fruit and vegetables can really protect people from many different diseases. On the other hand, animal fat can cause diseases. We can change our eating habits now and enjoy many years of healthy living.

The book that can’t wait
One problem a lot of people have with books is that they buy them and then never start reading them.
To  【1】, a foreign publisher called Eterna Cadencia came up with a very clever idea: it printed the words of the books in disappearing ink: the text of the book vanishes(消失) two months after the special package of the book is opened, so that encouraging buyers to start reading it 【2】 it goes away. They call this “the book that can’t wait.”
According to a video presented with the story, the book was  【3】 . The publisher sold out the whole first edition(版) at a bookstore the day it was printed, and received “thousands of requests” for more copies of the book. It also got a lot of news reports. As a result, the publisher is planning to publish   【4】 kinds of books in disappearing ink.
In some ways, the idea is pretty clever.【5】, we still have some suggestions:
First, the book should start the vanishing process after the reader first opens the book. If the vanishing ink books become very popular in the future, readers will need to read them one at a time. They don’t want their books to vanish before they read the first page.
Second, the vanished book should find a 【6】  use. Maybe they can be recycled, or maybe we can use them as notebooks. It would be a more environmentally friendly way to do this.

請閱讀下面的這篇文章，根據(jù)所提供的信息，完成信息卡，把答案寫在答題卷指定的位置上。
As a student, you must have homework every day. How do you deal with your homework? When do you usually finish your homework? Here is some advice for you to help you finish your homework well.
Homework should be done as soon as you get home from school. If you have after-school activities, the homework should be done first. At the same time, it is fine to allow for a snack break and also to allow for stretching(伸展) breaks.
Also, you should remember that it is your duty to do your homework. Don’t depend on Mum and Dad for help. Please try to find the answer yourself because you will learn much more that way.
When you have a question, especially something about a science or maths, don’t always turn to your teacher! It is a good idea to try to find the answer yourself. If this doesn’t work, you can also look at your textbooks carefully. They may help you understand the problem.
Finally, while doing homework, don’t think about or do other things. Keep working. Setting a time limit(限制) often helps with this. Different ages decide different amounts of time. 10-15 minutes is good for a child that’s aged 6-8. A time of 20-30 minutes is about right for a child aged 9-12. Kids can keep studying for 30-45 minutes at the ages of 13-15. This, of course, depends on your ability to pay attention and stay on tasks.
