　　排了近两个小时的队，玛丽终于把钱存进了海滨的一家银行。她走出银行，来到沙滩上，心理盘算着女儿教育的开销。她陷入深思，没有注意到天越来越暗。一只大海鸟俯冲下来在海滩上啄了个洞。狂风在海面上呼啸，把一棵树拔出地面。呼啸的海风和凶猛的海鸟要告诉她什么呢？女儿在国外能幸福生活吗？不能预见女儿在国外将怎样度过，她凝视这乌云，感到越来越担心。 答案：

　　Having queued for almost two hours and having had her money deposited in the bank near the beach，Mary walked out of the bank and went to sit on the beach，reckoning up in her mind the cost for her daughter's education.

The wind was roaring across the sea，tearing a large tree off the ground. As she could not foresee what her daughter would go through in a foreign country，she stared at the dark clouds，feeling more and more worried.
