第三单元作业1AI lay in the hospital bed with my six-year-old daughter, Elizabeth, holding her in my arms. “Mommy, will you stay with me the whole time？” she asked, looking up. “You know I can't be in the operating room，” I said carefully, not wanting to frighten her. “But Daddy and I will be waiting right outside.” Elizabeth nodded, but her eyes looked troubled.Elizabeth had broken her right leg in July. Seven months later, it still hadn't healed (康复). In fact, it had gotten worse. She was here in the hospital for surgery (手术)．I wanted to tell her that everything would be okay and promise that this would be the last time she'd have to go through this. But what if something went wrong again? How could I comfort my daughter when I needed comfort myself?There was a knock at the door. A nurse? I thought. Time to say goodbye already? But the woman who came in wasn't a nurse. “Hi，”the woman said. “I'm a volunteer here, and I've got something fo r Elizabeth.” She handed a bright­blue box to my daughter.Elizabeth sat up and took the box. She opened it and started pulling out goodies one by one — candies, stickers, a lovely toy in the shape of a star. She hugged the star, perking_up for the first time since she entered the hospital. “Thank you，” she said. “I love them.” There was a big smile on her face. It had been so long since I saw that big smile.The gift was a great comfort not only to my daughter, but also to me.21．Why did the author's daughter feel upset?A．She would have surgery on her arm.B．The author had no time to play with her.C．She had to stay in the hospital for a long time.D．The author couldn't stay in the operating room.22．The author didn't make any promise because ________.A．there was no time for her to do soB．she wasn't sure of the result herselfC．she believed everything would be okayD．she thought there was no need for her to do so23．The underlined part “perking up” means “________”．A．having a rest B．thinking carefullyC．doing her best D．becoming cheerfulBOne part of the world is still largely unexplored. It is the deep sea. Over the years, many people have explored under the sea. But the first deep-sea divers wanted to find sunken treasure. They weren't really interested in studying the creatures of life there.Only recently have they begun to learn some of the mysteries of the sea.It's not easy to explore the deep sea. A diver must have a way of breathing underwater. He must be able to protect himself from great pressure. The pressure of air is about 15 pounds on every square inch. But the pressure of water is about 1,300 pounds on every square inch!The first diving suits were made of rubber. They had a metal helmet (头盔) with windows in it. The shoes were made of lead and weighed twenty pounds each! These suits let divers go down a few hundred feet, but they were no good for exploring the very deep waters. With a metal diving suit, a diver could go down 700 feet. Metal suits were first used in the 1930s.In 1927, a diver named William Beebe wanted to explore deeper than anyone had ever gone before. He was not interested in finding treasure. He wanted to study the creatures and plants of the sea. His friend invented a metal ball called the Bathysphere. It weighed more than 5,000 pounds, but in it Beebe went down 3,028 feet. He saw many things that had never been seen by humans before.24．People who first explored the deep sea hoped to ________.A．learn about the animals and plants of the seaB．solve some mysteries about the seaC．have an exciting trip in the seaD．discover treasure under the sea25．According to the text, what make(s) deep-sea diving difficult?A．The pressure of water.B．The temperature of water.C．The dangerous sea creatures.D．The heavy breathing equipment.26．What do we know about William Beebe from the text?A．He broke the diving record in his time.B．He failed to find the treasure he wanted.C．He met something terrible under the sea.D．He was the first diver to explore the deep sea.第二节(共10小题；每小题1.5分，满分15分)阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
