Milk is the most complete food in the world. It has many things that we need to help us grow. It can give us energy and good health. Milk is a food enjoyed by people of all ages as we can easily digest it.
Milk is produced by all mother animals to feed their babies after they are born. Some such as cows produce more milk than their young ones need, so the extra milk is used by people. Nowadays, baby cows are often taught to eat solid food earlier, so that we can use most of the cow’s milk. A cow can produce as much as 45 liters of milk a day. She will give good milk if she is fed on rich grass. Many products can be made from cow’s milk. The simplest is cream, which is made from the fat of the milk. Butter is made from cream. Cream is also used for making cakes and other foods. Another common milk product is cheese. Cow’s milk can be also turned into powdered milk.
In countries where cows are not raised, people get milk from other animals. The buffalo gives milk to the people of India. In China, Iran and Turkey, a large number of sheep and goats are kept for their milk. And many Arabs drink camel’s milk. For babies, however, the best of all is their mother’s milk which is given to them during their first few months of life.

At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars．Our own planet, Earth, is becoming more and more crowded and polluted．Luckily, we can start again and build a better world on Mars．
First of all, transport should be much better．At present, our spaceships are too slow to carry large numbers of people to Mars—it takes months．However, by 2100, spaceship can travel at half the speed of light．It might take us two or three days to get to Mars! Secondly, humans need food, water and air to live．Scientists should be able to develop plants that can be grown on Mars．These plants will produce the food and air that we need．However, can these plants produce water for us? There is no answer now.
There is a problem for us to live on Mars．Mars suck（吸力） us much less than the Earth does．This will be dangerous because we could easily jump too high and fly slowly away into space．To prevent this, humans on Mars have to wear special shoes to make themselves heavier.Life on Mars will be better than that on Earth in many ways．People will have more space．Living in a large building with only 10 bedrooms is highly possible．Many people believe that robots will do most of our work, so we have more time for our hobbies.
There will probably be no school on Mars．Every student will have a computer at home which is connected to the internet．They can study, do their homework and take exams in online schools．Each student will also have their own online teacher called “e-teacher”.
However, in some ways, life on Mars may not be better than that on the earth today．Food will not be the same—meals will probably be in the form of pills and will not be as delicious as they are today．Also, space travel will make many people feel ill．The spaceship will travel fast, so the journey to Mars will probably be very uncomfortable.
