中考阅读之细节理解题

【什么是细节理解题?】

在阅读理解测试中,很大比例的题目是考细节的。事实上在对历年试题的分析中发现,事实细节题的比例占一半以上。文章中的细节通常指的是作者为论证文章主题特别是论证段落的大意而使用的具体信息。因为就议论文和说明文而言,作者在阐明准备论述的问题或观点后,通常会用大量具体的事实细节去说明或支持它们。这些细节可以是理由、例子、数字,也可以采用下定义、作比较、对比、打比方等方法去组织。根据具体考查的内容或范围,事实细节题可以再细分为因果细节题、态度细节题、观点细节题、类比细节题、综合细节题和具体细节题。

考察该文章中有关事件发生的具体细节的题目,如:时间、地点、人物、事件、方式等;

?What

?When

例题精讲

My class will put on a short play in English at the end of the year. Yesterday our English teacher gave us copies of the play.

“Choose a character in the play whom you’d like to be, ”she told us. “This afternoon learn a few lines of this part for homework. Then tomorrow you can say those lines in front of the class. I’ll decide who play each part.”

I wanted to have one of the bigger parts in the play, so I choose the part of the king. He has a lot of lines to say. I learned them by heart.

This morning in our English lesson we had to say our lines. I acted the part of the king. When I said my lines, I put a lot of expression into my acting. I thought I acted really well.

Everyone in the class read a part and then the teacher who would play each part.

Many of the students in my class couldn’t act at all. They couldn’t even read without making lots of mistakes. I was sure that I would get a big part in the play.

However, the teacher gave me the part of a soldier. He has only one line. It is, “Yes, sir!”

I was very disappointed. At the end of the lesson I went up to her and asked her why I had such a small part.

“You put too much expression in your acting,” she said. “Good acting is not big acting. It is acting the audience can believe in.”

课后作业

My favourite great book is The Adventure of Tom Sawyer by Mark Twain. Tom lives with his aunt Polly in a quiet stree t of St Petersburg, Missouri. He’s a lively and clever young boy, and he finds himself in many exciting adventures (冒险) . He runs away with his two friends, Huck Finn and Joe, to an island in the

middle of the Mississippi River for several days. With Huck he goes looking for treasure, with Becky he gets lost in a cave, and finally, they find a box of gold.

My favourite scene in the book is when everyone thinks Tom is dead. He decides to go to his own funeral. He hides and watches for a time, and then suddenly he appears. Everyone is surprised to see him but they’re also pleased to see him alive.

Tom is the hero of the story, but there are other important characters. Huck is an outsider and everyone is afraid of him. Becky is pretty with fair hair, Joe is Tom’s best friend, and Injun Joe is the bad man of the story.

The theme of the story is about children growing up. It describes how strangers are seen in small towns of America. Finally, it talks about freedom, social rules and how people are punished (惩罚) for bad behavior.

Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it’s still read and loved by people all over the world today. And although it’s only a story, Twain wrote it in the everyday Engl ish of the southern states of America in the 19th century, so it sounds very real. Today it’s thought to be one of the greatest books in American literature. Go on — read it! I know you’ll enjoy it, too.

1. Where does Tom run away with his two friends?

A. To a quiet street.

B. To a small town.

C. To an island.

D. To a forest.

2. Who is the bad man in the story?

A. Huck Finn.

B. Injun Joe.

C. Becky.

D. Polly.

3. How did people feel when Tom appeared at his own funeral?

A. They were surprised and pleased.

B. They were surprised and sad.

C. They were worried and excited.

D. They were frightened and happy.

4. The whole book is mainly about .

A. freedom and social rules

B. children’s bad behaviour

C. the growth of young children

D. strangers in American small towns.

5. The writer writes the article to________.

A. ask us to read the book

B. tell us how popular the book is today

They sent out a task force headed by their best battleship Hood to hunt down theBismarck. On May 24, the Hood found theBismarck. It was a meeting that the German commander Luetjens did not want to see. His orders were to destroy the British ships that were carrying supplies, but to stay away from a fight with British warships. The battle didn’t last long. The Bismarck’s first torpedo(鱼雷) hit the Hood, which went down taking all but three of her 4,419 men with her. But in the fight, theBismarckwas slightly damaged.

(英语)中考英语阅读理解专项训练及答案 一、英语阅读(日常生活类) 1.阅读下列短文,从每题所给的A、B、C三个选项中选出最佳答案。 If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" (代)of your mobile network. But the symbols will become things of the past after 5G networks fully arrive. On March 30, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also become the first city in China to start testing 5G networks. About 100 times faster than 4G networks, 5G will let people download and upload data(数据) faster than ever before. But 5G won't just bring faster mobile internet. People can use it for many other things as well. For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem-lag(延迟). When the car "sees" an obstacle(障碍物), it sends this information to a data center and receives instructions, However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer. 5G could also be used to power the internet of things (IoT), that is, a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically (自动地) place an order online for eggs when it finds that there are no eggs left inside. (1)Which city was 5G tested for the first time? A. Beijing. B. Shanghai. C. Shenzhen. (2)What can we infer(推测) according to the passage?. A. 5G is widely used in China now. B. 5G networks will make our lives more convenient. C. There are no symbols at the top of our phones. (3)The writer uses self-driving cars as an example to . A. explain how 5G's fast speed can be helpful B. warn about the possible dangers of self-driving cars C. explain how self-driving cars work (4)What is IoT according to the passage? A. A robot that can do housework. B. An online store where you can buy anything. C. A large online network that connects things and people. (5)Which sentence is right according to the passage? A. 5G will help us buy eggs quickly. B. Robots can help us buy eggs online. C. Our refrigerator can order eggs online for us. 【答案】(1)B
