  ②事实上,莎士比亚就像所有真正伟大的诗人一样,无可争辩地应当获得“酷似创造”这个赞语。    

  ③这种对称普遍存在:生与死、善与恶、公正与偏斜、天使与魔鬼、苍穹与大地、规矩与变形、伟大与渺小……    

  ④对称普遍存在于莎士比亚的作品中,无处不有,俯拾皆是。    

  ⑤天才与红宝石一样,都有着双重反光,双重折射。

答:剔除的句子是____________;剩余的句子组成的语段顺序是______________。

Tomorrow was his girlfriend’s birthday and the young man was having a difficult time deciding on a present for her. She already had more clothes than she knew what to do with them, so he couldn’t get any kind of apparel. She never ate sweets, so candy was out of the question. What then? He had a very special reason for wanting to impress her with just the right gift; tomorrow he was going to make an offer of marriage to her.

He finally decided on perfume(香水). All girls liked perfume. That raised another problem, however. What kind did she prefer? He couldn’t ask her because that would ruin the surprise.

At last the young man hit upon a brilliant idea. That afternoon, pretending to take his girlfriend’s fox terrier, a little dog for a walk, the young man and the dog went directly to the perfume counter of the town’s biggest department store. Good! There was a large array (长列) of perfume. He beckoned(招呼) a clerk, instructing her to open a large number of bottles and wave the stoppers under the dog’s nose.

Nestled in the young man’s arms, the terrier began to be restless and bored as this seemingly pointless game went on. Then Fritz suddenly became frisky, wiggling in the young man’s arms and barking excitedly, as the clerk waved one stopper under its nose.

“I’ll take that one,” said the young man to the clerk. The price was high, but it was worth it, he thought.

“My favorite perfume!” said the delighted girl the next evening as she unwrapped the package. “How did you know?” she asked, dabbing some perfume behind each ear.

“Intuition(直觉), I guess.” said the young man, deciding that it wasn’t exactly wrong to tell a lie under the circumstances. One day, after they were married, he would admit that his intuition had really been a little dog named Fritz.
