1．For several days Ⅰ（Jane Eyre） saw little of Mr.Rochester.One evening，I was invited to talk to him after dinner.There was a smile on his lips，and his eyes were shining brightly.As I was looking at him，he suddenly turned around and asked me， "Do you think I'm handsome，Miss Eyre？"
The answer somehow slipped from my tongue before I realized it： "No，sir."
"Ah，you are really unusual!You look like a quiet，serious little person，but you can be almost rude."
"Sir，I'm sorry.I shouldn't have given an immediate answer to such a question about appearances；I should have said that beauty doesn't matter，or something like that."
"No，you shouldn't!I see，you criticize my appearance，and then you stick a sly penknife under my ear!You have honesty and feeling.There are not many girls like you.Perhaps you have awful faults to counterbalance（抵消） your few good points."
I thought to myself that he might have too.He seemed to read my mind，and said quickly， "Yes，you're right.I have plenty of faults.I went the wrong way when I was twenty-one，and have never found the right path again.I might have been as good as you，and perhaps wiser.I am not a bad man，take my word for it，but I have done wrong.It wasn't my character，but circumstances that were to blame.Why do I tell you all this？Because you're the sort of person people tell their problems and secrets to，because you're sympathetic and you give them hope."
"Don't be afraid of me，Miss Eyre，" he continued." You don't relax or laugh very much，perhaps because of the effect Lowood has had on you.But in time you will be more natural when you're with me，and laugh，and speak freely.You're like a bird in a cage.When you get out of the cage，you'll fly very high.Good night."
（1）Why did Mr.Rochester say "and then you stick a sly penknife under my ear" in paragraph 5？
A．Because Jane had offered some unnecessary explanations.
B．Because Jane had intended to be more critical.
C．Because Jane had regretted having talked to him.
D．Because Jane had intended to kill him with a knife.
（2）From what Mr.Rochester told Miss Eyre，we can conclude that he wanted to.
A．tell her all his troubles
B．tell her his life experience
C．change her opinion of him
D．change his circumstances
（3）Mr.Rochester soundedat the end of the passage.
A．rude
B．cold
C．friendly
D．encouraging發(fā)布：2025/1/1 18:0:1組卷：11引用：2難度：0.5 -
2．My motivation for starting our family tradition of reading in the car was purely selfish：I could not bear listening to A Sesame Street Christmas for another 10 hours．My three children had been addicted to this cassette on our previous summer's road trip．
As I began to prepare for our next 500-mile car trip，I came across a book Jim Trelease's The Read Aloud Handbook．This could be the answer to my problem，I thought．So I put Roald Dahl's James and the Giant Peach into my bag．When I began to read aloud the tale of the boy who escapes the bad guys by hiding inside a giant peach，my three kids argued and wrestled in their seats．But after several lines，they were attracted into the rhythm of the words and began to listen．
We soon learned that the simple pleasure of listening to a well-written book makes the long miles pass more quickly．Sometimes the books we read became highlights of the trip．I read Wilson Rawls's Summer of the Monkeys as we spent two days driving to the beach．We arrived just behind the power crews restoring（恢復(fù)）electricity after a tropical storm．The rain continued most of the week，and the beach was covered with oil washed up by the storm．When we returned home，I asked my son what he liked about the trip．He answered without hesitation，"The book you read in the car． "
Road trips still offer challenges，even though my children now are teenagers．But we continue to read as we roll across the country．And I'm beginning to see that reading aloud has done more than help pass the time．For at least a little while，we are not shut in our own electronic worlds．And maybe we've started something that will pass on to the next generation．
（1）Why did the author start reading in the car？
A．She wanted to have a better journey．
B．She wanted to keep a family tradition．
C．Her children were addicted to reading．
D．Her children were tired of the cassette．
（2）How did the children react after the author read a few lines？
A．They kept fighting．
B．They hid themselves．
C．They soon settled down．
D．They read together aloud．
（3）What can we learn about the author and her family's trip to the beach？
A．They were caught in a storm．
B．They enjoyed reading on the road．
C．They had a good time on the beach．
D．They thought it had passed too quickly．
（4）Which can be the best title for the text？
A．Better Traveling than Reading
B．Books that Changed My Children
C．Road Trips Full of Challenges
D．Reading Makes Great Road Trips發(fā)布：2025/1/30 8:0:1組卷：0引用：1難度：0.7 -
