Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air,water and sunlight. Animals and man cannot make food from air,water and sunlight. Animals get their food by eating plants and other animals.Therefore animals and man need plants in order to live.This is why we find that there are so many plants around us.

If you look carefully at the plants around you,you will find that there are two kinds of plants:flowering plants and non-flowering plants.

Flowering plants can make seeds（种子）. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）. Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.

We now think of chocolate as sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it is an ingredient in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers.

　 Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say “Ugh!” and run away. Workers must first dry and then roast the beans. This removes the bitter taste.

　 The word “chocolate” comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink.

　 When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too. Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion.

　 In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.

　 Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are chocolate cream pie and of course an ice cream sundae with hot fudge sauce.
