    [高分句型]


    A. They all have a long history. B. They all offer treeless scenery.
    C. They are places where you can enjoy beaches. D. They offer chances to enjoy colourful leaves.
    B
    The first time I met Jane, we became best friends. We enjoyed the same things. We were excited to find each other. Our families became friends and everyone knew wherever you found Jane, you found me. Jane was at my house quite often that summer. We played and practiced flutes（长笛）.
    When school began, we talked on the phone and went over to each other’s houses. Then it seemed as if we were put to a test. We both made new friends. Jane started to hang out with hers. We rarely talked on the phone. When we did take a minute to talk, one of her new friends would come up and Jane would walk away with her, leaving me hurt.
    I’m sure she didn’t know how bad I felt. I began to hang around with my new friends, but it wasn’t the same. I met Erma, also a friend of Jane’s. She was in the same situation. We decided to talk to Jane.
    The call was not easy. However, when we talked on the phone, we were friends again. I explained my feelings and so did she. I realized I was not the only one hurting. She also felt left out. There were times when I didn’t even notice I was ignoring her. We talked for a long time and I felt a heavy weight lifted off my heart. We decided we wanted to be with our new friends, but would never forget the fun and friendship we had.
