myself，“Why would anyone bring home all his books on Friday？He must really be a nerd(a foolish person)．”I had quite a weekend planned，so I shrugged my shoulders and went on.‎ As I was walking，I saw a bunch of kids running towards him.They knocked all his books out of his arms and tripped(绊倒) him so he landed in the dirt.His glasses went flying，and I saw them land in the grass about ten feet from him.He looked up and I saw this terrible sadness in his eyes.So，I jogged over to him and as he crawled around looking for his glasses，I saw a tear in his eye.‎ As I handed him his glasses，I said，“Those guys are jerks.They really should go to hell.”He looked at me and said，“Hey，thanks！” There was a big smile on his face.It was one of those smiles that showed real thankfulness.I asked him where he lived.As it turned out，he lived near me.‎ Over the next four years，Kyle and I became best friends.I teased him all the time about being a nerd.He had to prepare a speech for graduation.As he started his speech，he cleared his throat，and began.“Graduation is a time to thank those who helped you make it through those tough years.I am here to tell you a story.”‎ I just looked at my friend in disbelief as he told the story of the first day we met.He had planned to kill himself over the weekend.He talked of how he had cleaned out his locker so his mom wouldn’t have to do it later and was carrying his stuff home.He looked hard at me and gave me a little smile.“Thankfully，I was saved.My friend saved me from doing the unspeakable.”‎ I heard the gasp(倒吸气) go through the crowd as this handsome，popular boy told us all about his weakest moment.I saw his mom and dad looking at me and smiling that same grateful smile.Not until that moment did I realize its depth.‎ ‎1．Why did Kyle carry all of his books home?‎ A．Because it was Friday.‎ B．Because he was a nerd.‎ C．Because he wanted to kill himself.‎ D．Because he liked doing things for his mother.‎ 答案　C 解析　细节理解题。根据倒数第二段尤其是第二句“He had planned to kill himself over the weekend.”可知，Kyle之所以把所有的书搬回家是因为他想自杀。故选C。‎ ‎2．Which of the statements is TRUE according to the passage?‎ A．The bunch of kids attacked Kyle to have his glasses and books.‎ B．The author planned to study all weekend after he met Kyle.‎ C．The author was a freshman when Kyle gave the speech.‎ D．Kyle felt grateful to the author for his help.‎ 答案　D 解析　细节理解题。根据倒数第二段最后一句“Thankfully，I was saved.My friend saved me from doing the unspeakable.”可知，Kyle对作者的帮助十分感激。故选D。‎ ‎3．What can we infer from the passage?‎ A．When Kyle couldn’t find the glasses，he turned to the author for help.‎ B．The author teased Kyle a lot about being a nerd.‎ C．The author didn’t expect Kyle to tell the story.‎ D．Kyle thanked his parents first for saving his life.‎ 答案　C 解析　推理判断题。根据倒数第二段第一句“I just looked at my friend in disbelief as he told the story of the first day we met.”可知，作者难以置信地看着Kyle讲着他们第一天见面的故事，由此推断作者没有料到Kyle会讲这个故事。故选C。‎ ‎4．What does the underlined word “them” in the 2nd paragraph refer to?‎ A．The kids. B．Kyle’s books.‎ C．Kyle’s glasses. D．Kyle’s arms.‎ 答案　C 解析　代词指代题。根据画线词所在句“His glasses went flying，and I saw them land in the grass about ten feet from him.”可知，them指代的是前面提到的his glasses。故选C。‎ B A New Jersey woman is waging a campaign to become the world’s heaviest living woman.Donna Simpson,42，weighs more than 600 pounds and aims to reach 1,000 pounds.‎ The mother of two children，ages three and fourteen，models on a website called supersizebombshells.com.where admirers and the curious can pay to watch videos of her eating junk foods or walking to the car.She has appeared in television interviews and said she welcomed media coverage.‎ A Guinness World Records spokeswoman said Donna Simpson has submitted a claim for the title of world’s heaviest woman to give birth，a claim that is being reviewed.Among the heaviest women ever recorded were one who reportedly weighed 1,800 pounds and another who reportedly weighed 1,200 pounds at the time of their deaths.‎ Donna Simpson said she had received a book offer and wanted her own reality show，partly to give plussize women more confidence.She wears size XXXXXL clothes，which she buys mostly online.‎ Donna Simpson has found a man who says he appreciates her size，and they plan to marry in Hawaii this year.She says airlines are being accommodating of her needs.Her fiancé (未婚夫) 49yearold Philippe and the father of her 3yearold daughter，said he not only finds Donna ‎ attractive but is also one of Donna Simpson’s biggest fan in her quest to expand her waist.‎ ‎5．How many pounds does Donna Simpson aim to gain?‎ A．400 pounds. B．600 pounds.‎ C．1,000 pounds. D．1,800 pounds.‎ 答案　A 解析　细节理解题。根据第一段中的“...weighs more than 600 pounds and aims to reach 1,000 pounds”可推知，Donna Simpson需要增加400磅。‎ ‎6．What do we know about Donna’s clothes from the text?‎ A．Donna makes them on her own.‎ B．Donna purchases them online.‎ C．Some people offer them to her.‎ D．Their size is the largest.‎ 答案　B 解析　细节理解题。根据第四段中的“which she buys mostly online”可知答案为B项。size XXXXXL不一定就是最大的号，排除D项。A、C两项文中并未提及。‎ ‎7．Which statement is TRUE according to the text?‎ A．Guinness World Records has received Donna’s claim.‎ B．Donna Simpson doesn’t like media coverage at all.‎ C．The heaviest living woman weighs 1,800 pounds.‎ D．Donna Simpson and Philippe have married recently.‎ 答案　A 解析　细节理解题。根据第三段中的“A Guinness World Records spokeswoman said Donna Simpson has submitted a claim for the title of world’s heaviest woman to give birth，a claim that is being reviewed.”可知Guinness World Records已经收到申请。根据第二段中的“she welcomed media coverage”排除B项；根据第三段最后一句排除C项；根据最后一段中的“they plan to marry in Hawaii this year”排除D项。‎ ‎8．What is Philippe’s attitude to Donna’s campaign?‎ A．Indifferent. B．Doubtful.‎ C．Critical.
