二、阅读理解 (共4小题；每小题5分，满分20分)
When I was 12 years old, I already knew that my teen years was going to be the worst years of my life. I was a total outsider, bullied(欺侮) at school. I felt completely alone in my small town.
But by starting to do volunteer work when I was 14, I turned my problem into a passion for helping others. The opportunity to practice kindness made me feel like my life had a greater purpose. The more positive might I shared, the more kindness and appreciation I received. I realized that my purpose in life would be to reach out to people, especially teenagers, and help them feel less alone.
Books were my true friends back then. I was so thankful that the authors wrote those books. The kindness they offered me with their books saved my life. One of my biggest dreams was to become an author so I could write books that would help other teenagers the way those books assisted me.
After surviving terrible experiences at school and at home, I made a choice to take the optimistic, positive road in the next steps of my journey. My dream career, one that I thought was only possible for the authors I loved, is what I am doing now. I have been a full-time author of teen novels since 2007 and am grateful for this precious opportunity to reach out to readers every single day.
Kindness saved me when I needed help the most. Even small acts of kindness can change someone else's life. You never know what anyone else is going through. But by practicing daily kindness, you become an architect of positive changes.
1.What was the author's life like when he was 12
A.Boring. B.Unpleasant. C.Peaceful. D.Meaningful.
2.How did the volunteer work benefit the author
A.It made him popular in his town.
B.It helped him understand others' lives better.
C.It helped him find the meaning of life.
D.It helped to shape his dream career.
3.Why did the author choose writing as his job
A.He wanted to share his school experiences.
B.He could pass positive energy to readers.
C.He was inspired by his teacher.
D.He found he had a talent for writing.
4.What does the author advise readers to do in the last paragraph
A.Say "no" to bullies bravely.
B.Make positive changes in their lives.
C.Learn to care more about others' feelings.
D.Treat others with kindness in daily life.
三、(共5小题；每小题4分，满分20分)
Volunteering is a great benefit to the community. Many nonprofit organizations couldn't survive without volunteers. However, you may not realize how much it also benefits your career.
●Volunteer in different areas.
You may be likely to just volunteer at one place, and that can be fine. ①____ ____Doing so can help you explore what you'd like to do later in life if you're younger or even choose a different career if you're a little bit older.

●④________

答案以及解析
一、
答案以及解析
1.答案：to
解析：考查介词。句意：我建议他制定一个新计划，但他对此没有回应。respond to...“回应……”为固定短语。故填to。
2.答案：appointed
解析：句意为：典礼指定好的时间就要到了。appointed为形容词，意为“事先约定好的”。
3.答案：rejecting
解析：考查非谓语动词，句意：这是我第一次成功地拒绝了他的悲观主义思想。分析句子结构和意思可知，空格前面是介词in，所以后面用动名词形式，做宾语。故填rejecting.
4.答案：scares
解析：考查动词时态。句意：我的哥哥总是保持平静，无论遇到怎样紧急的事情，他从未害怕。分析句子可知，提示词scare与keeps是并列谓语动词，表示"害怕，恐惧"，为不及物动词，也应用一般现在时，又因主语My brother是单数名词，所以scare应用一般现在时单数形式。故填scares。
5.答案：be replaced
解析：考查被动语态。句意：人们相信在课堂上，老师将不会被电脑代替。分析句子可知，提示词replace是宾语从句谓语动词，与主语teachers是被动关系，用被动语态，与空格前助动词will构成一般将来时的被动语态will be replaced。故填be replaced。
6.答案：Having waited
解析：考查非谓语动词。句意：在公园等了她两个小时之后，我不得不离开了。分析句子结构和意思可知，句子主语I是动词wait的发出者，存在逻辑上的主谓关系，所以用现在分词形式，表示主动；动词wait发生在谓语动词had to leave之前，所以用现在分词的完成式。故填Having waited。
7.答案：energetically
解析：考查副词。句意：这个公司也正在向国外市场积极地推销它的新产品。分析句子结构可知，空格处用来修饰谓语动词is marketing，故用副词修饰动词。Energy意为"能力，精力"，其形容词变形为energetic，意为"精力充沛的，积极的"，副词变形为energetically，意为"精力充沛地，竭力地，积极地"。故填energetically。
8.答案：published
解析：考查非谓语动词。句意：这位哲学家的论文将于下个月发表。分析句子结构和意思可知，动词publish和被修饰的名词his paper是逻辑上的动宾关系，所以用过去分词，做宾补。get sth. done"让某事被做"的意思。故填published。
9.答案：to admire
解析：考查不定式。句意：学生倾向于崇拜既严格又充满爱心的老师。tend to do是固定短语，意为"倾向于做某事"，因此空格处用不定式。故填to admire。
10.答案：had told
解析：考查if引导的虚拟条件句。句意：如果你事先告诉我，我就会去机场接他了。分析句子结构可知，if引导了虚拟条件句，根据主句中的would have met可知，本句话是对过去事实相反的假设，所以if从句中要用过去完成时态。故填had told。
二、
1.答案：B
解析：细节理解题。根据第一段第一句“When I was 12 years old, I already knew that my teen years was going to be the worst years of my life.(当我十二岁时,我已经知道我的青少年时代将是我一生中最糟糕的几年。)”和第二句“I was a total outsider, bullied at school.”可知,作者十二岁时的生活是不愉快的。故选B。A.无聊的;C.和平的;D.有意义的。
2.答案：C
解析：细节理解题。根据第二段第二句“The opportunity to practice kindness made me feel like my life had a greater purpose.(做善事的机会让我觉得我的人生好像有了更大的目标。)”和最后一句“I realized that my purpose in life would be to reach out to people, especially teenagers, and help them feel less alone.(我意识到我的人生目标将会是帮助人们,特别是青少年,帮助他们感觉不那么孤独。)”可知,志愿者工作帮助作者找到了生命的意义,那就是帮助别人。故选C。
3.答案：B
解析：推理判断题。根据第三段最后一句“One of my biggest dreams was to become an author so I could write books that would help other teenagers the way those books assisted me.(我最大的梦想之一就是成为一名作家,这样我就可以写书来帮助其他青少年,就像那些书曾经帮助我那样。)”可推断出,作者选择写作当工作是因为他可以通过写书来帮助其他青少年,把正能量传递给读者。故选B。
4.答案：D
解析：推理判断题。根据最后一段第二句“Even small acts of kindness can change someone else's life.(即使是小小的善举也能改变别人的一生。)”和最后一句“But by practicing daily kindness, you become an architect of positive changes.(但通过每天做善事,你会成为积极改变的缔造者。)”可推断出,作者建议读者在日常生活中善待他人。“Treat others with kindness in daily life.”是“practicing daily kindness”的同义表达,故选D。
三、
答案：①-⑤ GEFBD
解析：本文是一篇说明文。文章讲述了如何利用志愿工作帮助你发展事业。
①选项"然而，在不同的地方做志愿者会让你接触不同的领域。"呼应由小标题"Volunteer in different areas. (不同地区的志愿者)"，与上文"You may be likely to just volunteer at one place, and that can be fine. (你可能只想在一个地方做志愿者，这很好)"形成转折关系，引出下文"Doing so can help you explore what you'd like to do later in life if you're younger or even choose a different career if you're a little bit older. (这样做可以帮助你探索如果你年轻的话你以后想做什么，如果你年纪稍大一些，甚至可以选择不同的职业)"讲在不同地方做志愿者让你接触不同领域、有利于你职业规划的好处。故选G。
②由小标题"Use it to build skills. (用它来培养技能)"和上文"You may be likely to just volunteer at one place, and that can be fine. (志愿服务是培养自己技能的绝佳机会)"可知，承接上文，E选项"在你付出时间的同时，你也在学习新的东西。"和小标题呼应。故选E。

In fact, you have about a 25 percent higher chance of being hired if you volunteer than if you don't. If you don't have a high school diploma(毕业文凭), that number increases to a 50 percent higher chance .(研究表明，志愿工作者比不志愿工作者更有可能被雇佣。事实上，如果你做志愿者，你被录用的几率比不做志愿者高出25%。如果你没有高中文凭，这个数字会增加50%)"可知，此空选小标题，结合本段的内容和选项来看，B选项"增加你被录用的机会。"切题。故选B。
⑤由小标题"Put your volunteer experience on your college application. (把你的志愿者经历写在你的大学申请表上)"和上文"If you're still in high school, volunteering looks great on a college application. It shows leadership, initiative (主动性), and commitment, all things colleges love. (如果你还在高中，志愿工作在大学申请中看起来很不错。它显示了领导能力、主动性和承诺，所有这些都是大学喜欢的)"可知，作者建议把志愿者经历写在你的大学申请表上，承接上文，D选项"只要确保在申请时将其包含在申请表中即可。"中的"on your application"和小标题呼应。故选D。
