“Hungary?” I looked at my school headmaster in confusion. “I never mentioned wanting to go to Hungary. ” And with that, my adventure started.
My name is Jonathan Diamond and I just finished an amazing school exchange year in Hungary.
Going on an exchange had always been my dream. When my high school offered an all-year program ，I jumped at the opportunity. It would pay for almost everything and all I had to do was get a plane ticket. I knew where I wanted to go ： Spain ，the country of dancers wearing flowing red dresses. So when I heard that I was going to Hungary, I was pretty shocked. But I decided to make the best of it ，since it was ，after all ，a once-in-a-lifetime opportunity. Before I knew it ，I was on the airplane, leaving for Budapest International Airport, Hungary.
I had times when I almost gave up. Hungarian is the hardest language on the planet. Cultural differences occasionally embarrassed both my peer teens and me. I had to give up eating carrots, my beautiful favorite ，for they think carrots are rubbish in their country. The change in the landscape was amazing, looking nothing like skyscrapers, bullet trains ， cars ，and people in tiny houses that I had been accustomed to. Gradually, I fell in love with the relaxing lifestyle, the warm-hearted people, and getting home at 2： 30 p. m. at the latest from school. And I was sad to leave on my very last day.
Having the host family who took me as one of their own members was the best thing I ，ve ever experienced. From my little sisters ，I learned how to embrace life to its fullest. From my brothers I learned that it’s OK for a boy to run around the house. From my host parents I learned to stay positive ，to smile, and that when you pick the right persons and take their hands ，suddenly, you become friends.
28. How did Jonathan feel when he was told to go to Hungary?
A. Excited and satisfied.
B. Confused and shocked.
C. Amazed and embarrassed.
D. Delighted and interested.
29. Why did Jonathan still decide to go to Hungary instead of Spain?

B. He want ed to learn Hungarian.
C. It was a rare chance.
D. Going to Hungary was much cheaper.
30. What can we learn about Jonathan during his stay in Hungary?

B. He couldn’t wait to leave.
C. He was surprised by the landscape.
D. He quickly got used to the life there.

D
The Scottish composer Evelyn Glennie lost nearly all her hearing as a young girl, yet went on to a very
successful career in music including winning Grammy awards. When somebody asks her ，“How do you hear?” She responds ，“How do you hear? Is it only with your ears?” For Glennie, and fo r us too, listening is not only hearing ；it is understanding. We need to listen to what is said and unsaid, and also how it is said.
It' s important to hear what people say accurately. As Mark Twain said, “The difference between the right word and the almost right word is the difference between lightning and the lightning bug(萤火虫）." If you miss something or you’re not sure you’ve heard accurately, ask the speakers. At this point you’ re not evaluating ，just looking for accuracy and understanding. Here are som e ways to get clear about what they say and don’t say. Why are they saying this now, instead of sooner or later? Why are they emphasizing these points ，instead of something else?
Listen to how it is said. People send signals about what they mean with their voices and body language that sometimes differ from the words they say. While going through the next points, think about someone whose real meaning you might sometimes miss ，and see if any of these signals might come up. First, voices. When others speak, notice changes in their volume, pace ，and tone. Second, body language. Notice gestures, eye contact ，and facial expressions. Do these sync what they are saying, or do they tell a different story? Third ，emotions. What is the person apparently feeling? Now you might not know for sure, but be considerate, open to understanding, and ask thoughtful questions.
32. What’s the writer’s purpose of mentioning Evelyn Glennie?
A. To give an example of wise words.
B. To introduce a world-famous musician.
C. To help explain the meaning of listening.
D. To encourage us to fight against disability.
33. What can we learn from what Mark Twain said?
A. It is important to have a good knowledge of English words.
B. People should know words can be used in many different ways.
C. English is a very complicated language with a large vocabulary.
D. The slight difference between words may result in misunderstanding.
34. What does the underlined word “sync” probably mean?
A. Match.
B. Prove.
C. Describe.
D. Analyze.
35. Which is the best title of this passage?
A. Speak While You Listen
B. Listen Beyond Words
C. Read Between Lines
D. Think As You Talk
第二节 （共5小题；每小题2分，满分10分）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Traveling alone gives you the freedom to create your own schedule and do as you please. 36 For example, a travel partner can provide practical support and celebrate in the rewards of first-hand experience with unfamiliar locations and cultures.

成都高2018 届新高三零诊模拟测试语文试题 第Ⅰ卷阅读题 现代文阅读 阅读下面的文字,完成下列各题。（9分） 在历史学家的研究接近尾声之时，他将会面临这样的挑战：你研究的东西究竟有什么用处？你是否只是从自己的工作中找点乐子？你是否比一个很少读书的街头路人对人类本质 的认识更深刻？你是否从历史长河中发现了规律，能够用来预示人类未来的行动或国家的命运？有没有这样的可能：归根结底“历史没有任何意义”，它没有教给我们任何东西，它浩瀚无涯的过去只是错误的一再上演，而这些错误注定要在未来更大的舞台上，以更大的规模发生？ 我们不时会有这种感觉，而且还有许多疑虑冲击着我们的进取心。我们真的知道什么是过去，过去真的发生了什么吗？或者，过去只不过是一堆鲜有“定论”的“荒唐事”？我们 对于过去发生的认识，总是不完整的，很可能还是错误的，因为历史已经被相互矛盾的证据 和存有偏见的历史学家所遮掩蒙蔽，或者也可能被我们的爱国心或宗教偏见所曲解。“绝大部分历史是猜测，其余的部分则是偏见。”即使一个历史学家认为自己克服了诸如国籍、种族、信仰或阶级等偏见，他在材料选择和遣词造句上的细微差别，都会暴露出他的私人偏好。其次，我们通过从过去所得到的结论来推演未来，但是由于变化的加剧，导致这一行为会比过去任何时期都更有风险。今天一些年轻的物理学博士甚至认为，他们所学习的学科近几十 年的改变，超过了此前有历史记载的所有时期。每一年，甚至每一个月，都有一些新的发明、新的方法或者新的情况迫使人们对行为和观念做全新的调整。更有甚者，机遇的因素，或者说是自由的因素，似乎会进入到金属和人本身的活动运行中。我们再也不能确信，原子，更小的有机体，如我们所认为的在过去发生反应那样，将一如既往地会在未来发生相同的反应。 电子，如同库柏的上帝一样，神秘莫测，其奇妙的运行以及一些怪癖的特点或情况，或许就 能打乱国家之间的平衡。正如亚历山大，当他酗酒致死，导致了他的新帝国分崩离析；或者如腓特烈大帝，由于俄国继任沙皇醉心于普鲁士道路，从而避免了一场大的灾难。 显而易见，历史编纂不能算是一门科学。它只能算是一个行业、一门艺术和一种哲学一个搜集史实的行业，一门通过将混乱的材料有意义地排列起来的艺术，一种寻求预见性观点和启蒙作用的哲学。“当下乃为成事而拾掇的往昔，往昔尤为解惑而展开之当下。”这大约是我们所相信的和所期望的。就哲学而言，我们试图通过整体来了解部分。就“历史哲学”
