2017高考英语真题阅读理解总结一
I found out one time that doing a for for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were hing a final test. During the test, the girl sitting next to me whispered something, but I didn?t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I hened to he an extra one, so I took it out of my pocket and put it on her desk.
Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (负责任) for your own acts. For a long time, she talked about honesty and emphasized the fact that when people do something dishonest, they are really cheating themselves. She made me promise that I would think seriously about all the things she had said, and then she told me I could lee. I walked out of the room wondering why she had chosen to talk to me about all those things.
Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl?s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn?t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a for by letting her use my pen, I am sure she continued to believe that I had cheated on the test.

She showed me that hers was out of ink and would not write. I hened to he an extra one, so I took it out of my pocket and put it on her desk.
我发现一个时间,做一个人能给你带来很多麻烦。当时我在第八年级,我们有一个最后的考验。在测试期间,坐在我旁边的女孩低声说了些什么,但我不明白。我倚在她的方式,发现她想问我是否有额外的笔。她发现她是我的墨水用完,不会写。我碰巧有一个额外的,所以我把它从我的口袋里,放在她的办公桌上。
Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed.

后来,我发现她认为我在考试中了。当她看到我瘦了跟我旁边的女孩,好像我是从复制的女孩的试卷答案。我试图解释的笔,但她可以说是它似乎非常奇怪,她说我还没有谈到任何关于笔的一天,她跟我就在考试后。即使我试图解释说我只是做女孩的忙,让她用我的笔,我相信她仍然认为,我在考试中了。
2017高考英语真题阅读理解总结二
To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear.
Watch a good teacher, and you will see that he does not sit still before his class: he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality (音色) and the musical note of his voice always changing according to what he is talking about.
The fact that a good teacher has some of the gifts of a good actor doesn?t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher?s work and the actor?s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand (预先). What he has to do is to make all these carefully learnt words and actions seem natural on the stage.
A good teacher works in quite a different way. His audience takes an active part in his play: they ask and answer questions, they obey orders, and if they don?t understand something, they say so. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.
I he known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.
1. What is the text about ?
A. How to become a good teacher.
B. What a good teacher should do outside the classroom.
C. What teachers and actors could learn from each other.
D. The similarities(相似处) and differences between a teacher?s work and an actor?s.
2. The word ?audience? in the fourth paragraph means ____ .
A. students B. people who watch a play
C. people who not on the stage D. people who listen to something
3. A good teacher ____ .
A. knows how to hold the interest of his students B. must he a good voice
C. knows how to act on the stage D. stands or sits still while teaching
4. In what way is a teacher?s work different from an actor?s ?
A. The teacher must learn everything by heart .
B. He knows how to control his voice better than an actor .
C. He has to deal with unexpected situations .
D. He has to use more facial expressions .
5. The main difference between students in class and a theatre audience is that ____.
A. students can move around in the classroom
B. students must keep silent while theatre audience needn?t
C. no memory work is needed for the students
D. the students must take part in their teachers? plays
6. Why is it that some good teachers are unable to play well on the stage ?
A. Nobody has taught them how to act on the stage .
B. Their audiences are different .
C. It is impossible for them to do so much memory work .
D. They are not used to repeating exactly the same words .
7. Which of the following is true ?
A. Teachers he to learn by heart what they are going to say in class .
B. A teacher cannot decide beforehand what exactly he is going to say in class .
C. A teacher must speak louder than an actor .
D. A teacher must he a better memory than an actor .
To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear.
要成为一个好老师,你需要一些好演员的天赋;你必须能够抓住观众的注意力和兴趣;你必须是一个明确的扬声器,具有良好的,强有力的,悦耳的声音完全在你的控制之下;你必须能够按照你的教学,以明确其含义。
Watch a good teacher, and you will see that he does not sit still before his class: he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality (音色) and the musical note of his voice always changing according to what he is talking about.
看一个好老师,你会看到,他不坐他的课前,他代表整个时间他是教学;他走,用他的胳膊,手和手指来帮助他解释,他的脸表达感情。听他的,你会听到声音,质量(音色)和音乐注意到他的声音总是按照他所说的。
The fact that a good teacher has some of the gifts of a good actor doesn?t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher?s work and the actor?s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand (预先). What he has to do is to make all these carefully learnt words and actions seem natural on the stage.
事实上,一个好老师有一些好演员并不意味着礼物,他一定能够在舞台上表演好,有教师和演员的工作的。他说的话他熟记于心的很重要的差别;他必须准确地重复同样的话每次他扮演某个角色,甚至他的动作,他用自己的发音方式都是事先确定的(预先)。他所要做的是让这些用心学习的言语和行动似乎自然的舞台上。
A good teacher works in quite a different way. His audience takes an active part in his play: they ask and answer questions, they obey orders, and if they don?t understand something, they say so. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.
一个好老师的工作相当不同的方式。他的听众积极参与他的表演:他们提问和回答问题,他们服从命令,如果他们不理解的东西,他们这么说。老师必须满足听众的需要,这是他的学生。他不能了解他的心,但必须把它作为他走。
I he known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.
我知道有许多老师在课堂上是优秀的演员却不能在舞台上扮演角色,因为他们不能严格按照别人所写的。

People bury treasure to stop other people from taking it. They choose a quiet place, dig a deep hole and bury the treasure in it. Then they make a map of where the treasure is or write down other clues(线索)that will help them or someone else to find it again.
In Britain a few years ago; a writer wrote about some treasure that he had buried. He put clues in the story to help readers find it. Thousands of people hunted for the treasure. They dug holes all over Britain, hoping to find it.
One of the most popular adventure stories ever written is Robert Louis Stephenson's ?Treasured Island?, an exciting story about a young boy, Jim Hawkins, who is captured by pirates and later finds some buried treasure.
Then there is the true story about a man who had to trel overseas for a year. He did not trust banks, so he buried his life sings in a park. Then he went away. On his return, he went straight to the park. But the park was no longer there. In its place there was a huge building.
And then there was the man who buried his sings, all in bank notes, in a waterproof(防水的) bag. When he dug it up years later, there was nothing left. Worms and insects had eaten the bag and everything in it.
And of course, these are stories about people who bury things and either forget where they he buried them or lose the map.

二、阅读下面文字,完成7?10题。(共16分。每小题4分)
阅读下面的文字,完成下面试题
树木都是比较长寿的,自然界中常有许多百年以上的大树,甚至也有上千年的古树。一般比较准确地确定古树的年龄,多用?数年轮?的办法。
什么是年轮呢?就是木本植物茎干横断面上的同心轮纹,在树木茎干的韧皮部内侧有一圈细胞生长特别活跃,分裂也极快,能够形成新的木材和韧皮组织,被称为形成层。可以说树干的增粗全靠它的力量,这些细胞的生长情况在不同的生长季节中有明显的差异。春天到夏天的天气是最适于树木生长的,因此形成层的细胞分裂较快,生长迅速。所产生的细胞体积大,细胞壁薄,纤维较少,输送水分的导管数目多,称为春材或早材;到了秋天,由于形成层的细胞的活动逐渐减弱,产生的细胞当然也不会很大,而且细胞壁厚,纤维较多,导管数目较少,叫做秋材或晚材;当年的早材与晚材逐渐过渡,组成一轮,而晚材与次年的早材之间,界限分明,出现轮纹,根据树干基部的年轮,可以推测树木的年轮。
但是也有一些植物,如柑橘,年轮就不符合这种规律,我们叫它?年轮?,因为它们每一年能够有节奏地生长三次,形成三轮。此外,在热带地区的树木,由于气候季节性的变化不明显,形成层所产生的细胞也就没有什么差异了,年轮往往不明显。
古树年轮的研究,对近年开展的古气候讨论以及空气污染情况的研究都大有助益,首先树木的生长与气象的关系最为密切,从年轮宽,生长量大,推出那一时期风调雨顺,气温适宜;反之,年轮窄,则雨水稀少或干旱无雨,或气温过高或过低。美国科学工作者通过研究450株?世界爷?的年轮,发现它所记录的近百年气候变化,竞与现有文字记录相吻合;我国兰州大学在祁连山区集900岁以上的圆柏树,发现其年轮宽窄变化与我国近1000年的气候变化相一致。此外,用科学手段,可以从年轮里观察出空气污染的程度,美国有人对二氧化碳及氧化物散落较多的军工厂附近的43株美国五针松及50棵鹅掌楸进行年轮分析,发现这些树木的历年生长量与该厂排放的污染物质的多少有密切关系,污染物多,树木生长量就少。
第7题单选 下列对树木年轮的解释,最准确的一项是( )
A.树木年轮就是木本植物茎干横断面上的同心轮纹。
B.树木年轮是木本植物的主干由于季节变化生长快慢不同,在木质部的断面显出的环形纹理。
C.在树木茎干的韧皮部内侧有一圈细胞生长特别活跃,分裂也极快,能够形成新的木材和韧皮组织,它们就是树木年轮。
D.当年的早材与晚材逐渐过渡,组成一轮,而晚材与次年的早材之间,界限分明,出现轮纹。
参考答案:B
第8题单选 下列对?根据树干基部的年轮,可以推测树木的年轮?这句话的理解错误的一项是( )
A.树木都是比较长寿的,自然界中常有许多百年以上甚至上千年的古树。
B.树木茎干的韧皮部内侧的细胞在不同的季节生长情况有明显的差异。
C.当年的早材与晚材逐渐过渡,组成一轮,而晚材与次年的早材之间,界限分明,出现轮纹。
D.除个别植物外,大多数植物符合这种一年增长一轮的规律。
参考答案:A
第9题单选 下列对古树年轮研究的益处,表述不正确的是( )
