• 18．阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
  A Narrow Escape There was a huge three-acre pond just a few kilometers from where we stayed.Since moving into our new home in the countryside，my brother，Jim and I used to steal out to the pond where we would meet another friend.Dad had warned us not to venture anywhere near the pond area，especially after a friend informed him that a crocodile had been spotted there.We took no notice of his advice though.This was our favorite hideout and we were certainly not going to give it up.
      On this particular afternoon，the three of us had just finished swimming.Jim and Syed were reluctantly making their way towards the spot where they had left their clothes.I stayed back and was bathing in the waist-deep water when I suddenly became aware of ripples（波纹）forming on the surface of the water.I looked at the ripples and my eyes caught a motion in the water.A crocodile，I thought.Then I saw it -its mouth and its two terrible eyes，" Jim ..." I whimpered.Then I screamed with all my strength.
      Jim turned his head in my direction and immediately recognized the danger. "Get out of the water，Jeff.Hurry!It's just behind you."
      I struggled clumsily in the water.After a few ups and downs，I reached the edge of the pond.I looked over my shoulder.Moving swiftly towards me was an enormous crocodile.I froze.Then suddenly I felt a burning pain in my leg.Meanwhile，Jim and Syed screamed and started throwing stones at the crocodile and managed to distract it.The crocodile went for them now.As it opened its jaws，I could see its jagged teeth.I tried to move but a fierce pain shot through me.With the last strength，I struggled out of the pond.
