    Imagine a world without fruit. We wouldn’ t be very healthy. We get a lot of important vitamins from eating fruit.
    We think of fruit primarily as something to eat.【T1】________  Fruit is part of a flowering plant and it carries the seeds. The purpose of fruit is to protect a plant’ s seeds and help them get spread about. Wind and water spread seeds. So do animals when they eat fruit and drop the seeds.【T2】________
    There are two main types of fruit; fleshy and dry. Fleshy fruits are soft and juicy. Pears, bananas and apples are all fleshy fruits.【T3】________ Grains like wheat and rice, or nuts like chestnuts (板栗), are dry fruits.
    But wait: You’ ve eaten oranges and grapes without seeds. How can they be fruits? It’ s because people have changed the way they grow fruit. They can now grow seedless fruit. Seedless fruit comes from special plants that are made by combining two varieties of a fruit to form a new variety. These special plants grow and produce seeds.【T4】________These plants cannot reproduce themselves.  They can make fruit, but the fruit has no seeds.
    Fruits are a source of substances that keep us alive and healthy. So people make use of fruits for many foods. We make juices from them. We make jams and sweets.【T5】________Beer comes from grains and wine comes from grapes, and some particular wines are made from apples, peaches, or other fruits.
    A. Dry fruits are thin and hard.
    B. We even make alcohol from fruit.
    C. But fruit has a purpose quite apart from our needs.
    D. So these plants produce fleshy fruits.
    E. Then the seeds grow into new plants.
    F. But the plants grown from these seeds are seedless.
