　　“Mom！” Ben cried.“Look！” Just ahead，a car had lost control on a patch of ice.Barbara pulled over，and threw open her door.Thank goodness she was a nurse—she might be able to help these unfortunate passengers.

　　Then she paused.What about Ben? She couldn't take him with her.Little boys shouldn't see scenes like the one she anticipated(预料)．But was it safe to leave him alone? What if their car were hit from behind?

　　For a moment Barbara considered going on her way.Someone else was sure to come along.No! “Ben，honey，promise me you'll stay in the car！”

　　“I will，Mommy，” he said as she ran.It was worse than she'd feared.Two girls of high school age are in the car.One was dead.The driver，however was still breathing.Barbara quickly applied pressure to the wound in the teenager's head.If help came soon，the girl would live.

　　Barbara called for help on her cell phone and soon she heard the ambulance sirens(报警器)．

　　“Good job，” one said as he examined the driver's wounds.“You probably saved her life，madam.”

　　Slowly Barbara opened her car door.What should she tell Benjamin? He was staring at the crash site，his blue eyes huge.“Mom，” he whispered，“did you see it？”

　　Actor Russell Brand bought his new bride Katy Perry，a singer，the most extreme wedding present anyone could imagine：a tiger! The couple got married at the Aman－i－Khas resort in Rajasthan，India yesterday and Russell supposedly surprised his new wife with Machli，a female Bengal tiger who lives in the Ranthambore National Park，near the place where he proposed(求婚) and got married.

　　Although a statement released by the couple revealed the ceremony was performed by a Christian minister and long－time friend of Katy's family，it is believed the wedding maintained some Indian traditions.The bride and groom wore traditional Indian clothes with Katy wearing a sari(纱丽) while on Friday，at a celebration before their wedding ceremony，she had henna(指甲花) designs applied on her palms and hands.The wedding place was decorated with lamps，colourful lights and flower garlands(花环) while two elephants named Laxmi and Mala were also part of the wedding ceremony.

　　Ⅲ.阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

　　My six－year－old daughter，Caitlynd，and I stopped at a shop for some candy.As we were going out the door，a boy was coming in.The boy had a big scar in his face __29__ made him very ugly.He held a skateboard under one arm and a basketball under the other.

　　Caitlynd，who was walking ahead of me，__30__ (stop) when she saw the boy.I thought the ugly boy scared her，and she'd frozen on the spot.But I was wrong.Caitlynd backed up against the door and opened it wide.So it was much __31__ (easy) for the boy to pass it.Now I was face to face with the boy.I stepped aside and let him pass.He replied “Thank you very much.” __32__ (polite)．

　　On our way to the car，I commended Caitlynd __33__ her manners in holding open the door for the boy.She didn't seem to be __34__ (scare) by his appearance，but I wanted to make sure.If a __35__ (mother) talk about freedom of self－expression and allowing people their differences was in order，I wanted to be ready.As it turned out，__36__ was I who needed the talk.The only thing Caitlynd noticed about the boy was the fact that his arms were full.“It was __37__ (difficulty) for him to open the door.”

　　I saw the ugly scar in the boy's face，but she saw a person carrying something under each arm and __38__ (head) toward a closed door.

　　答案　

　　29．which/that　[考查定语从句引导词。made him very ugly前面缺少指代scar这一名词的主语，故用which或that引导定语从句。]

　　30．stopped　[考查动词时态。本文主体时态为一般过去时，该stop的过去式。]

　　31．easier　[考查形容词比较级。Caitlynd将门打开得宽宽的，使得小男孩更容易通过。]

　　32．politely　[考查词性转换。空格处所填单词应该修饰动词replied，故用副词形式。]

　　33．for　[考查固定搭配中的介词。commend sb for sth是固定搭配，意为“因为某事而表扬某人”。]

　　34．scared　[考查被动语态。根据空格后面的by his appearance可知， Caitlynd没有被小男孩的相貌吓住。]

　　35．motherly　[考查词性转换。mother为名词，而空格处需要填一个形容词，用以修饰其后面的名词talk。motherly为形容词，意为“母亲般的；慈母般的”。]

　　36．it　[考查代词it的用法。It is/was...who/that...是强调句型结构。]

　　37．difficult　[考查词性转换。空格前面的was决定了空格处应该填difficulty的形容词形式。]

　　38．heading　[考查词性转换。空格所填单词的形式应该与carrying一致，故填heading。]
