3.I like the English songs and they        many times on the radio.(  )
A.have been taughtB.have taught
C.had been taughtD.had taught

分析 我很喜欢这些英文歌曲它们在收音机上被教过好多次了.

解答 答案是A.考查被动语态,分析句子并列句中的主语是they指的是英文歌曲,歌曲与动词teach是被动关系,根据语境已经教了好多次了,所以用现在完成时,故答案选A.

点评 被动语态由"助动词be+及物动词的过去分词"构成.被动语态的时态变化只改变be的形式,过去分词部分不变.疑问式和否定式的变化也如此.掌握各种时态的被动语态是解题的关键.

11.In a recent airing of"Unsolved Mysteries",there was a young boy who was the victim of the  holocaust(大屠杀).He'd been(1)Bin a work camp for several years and somehow had managed to  survive the(2)A of his imprisonment.
The story was of a boy-now in his sixties-ad his quest to find an American soldier who had(3)Da kindness to him by(4)Bsome food.It might seem(5)C,but to this child,who had seen  nothing but(6)Dand inhumanity for as long as he could remember,it was a(7)Cthat marked a  turning point in his life,for he had lost hope.When he was liberated by the American forces,he was dying.He,(8)D needed food.As he was staggering along the road a young soldier(9)B down from his tank and gave him some of his supplies.With this one act of generosity,a kind American had aroused the(10)Dagain that there really was some good in the world.And the boy never(11)A it.The boy later went to America,raised a family,became successful and worked hard to repay the(12)C he had received with his own.
Actually there were so many similar acts of generosity that it would be almost impossible to know for sure who the soldier was.
Weall have a choice:to create more light in the world.As Confucius(13)B it over 2500years ago,"It is better to light one small candle than to(14)A the darkness."
As the story above so nicely (15)C  small gestures can often generate huge blessings.If we're constantly  looking for and doing kind acts,we will no doubt bring more joy into the world around us as well as into our own world!

15.Are you a bookworm?Is your head stuck in a book for long?If so,that's a good thing.There are many benefits to reading.Getting into a good novel improves our literacy(读写能力).But who or what encourages us to pick up a book and start reading?
    Of course,when we are young,our parents and teachers inspire us by introducing us to  characters that we love-or love to hate.And there are the authors-the people who invent and write about these characters.Good writing can really catch our imagination.
    One modern-day children's author is J.K.Rowling,who's known for her books about the wizard,Harry Potter.Last year she was named as a‘literacy hero'for her part in improving people's love of reading.The UK's National Literacy Trust awarded her the title for"turning a generation of children into readers."
    The Trust also honoured schoolchildren,a librarian and teachers for their effort in trying to get people to read.The actor,Henry Winkler,who has dyslexia(阅读障碍),Was also named for the books he has written about a boy with learning difficulties.
    Reading books is more than an enjoyable pastime;it can also help people in difficult circumstances.The author Pat Winslow worked as a writer in prisons and found reading and discussing stories helped prisoners reflect on their patterns of behaviour.She says"Very often we would have discussions about the moral compass of a character,what was the motivation of
somebody,why did they behave that way?"
    Today I like to read factual books such as biographies,where you get an insight into the lives of important and well-known people.I also enjoy looking at travel books and learning about journeys and new destinations.It's a good substitute if you can't visit in person.
    But the main benefit of reading is the improvement it brings to our literacy.The more we do it,the better we get and who knows-one day you may become the next Tolstoy,Jackie  Collins or even William Shakespeare.

12.Homework will not be a concern for pupils attending a pioneering new secondary school in Norfolk.Instead,the  l,100 children will stay longer at school,doing extra study at school as part of the extended (延长的) school day,which could last until about 5 pm.
     Rather than setting homework that pupils could struggle with at home,where there may be limited access to computers,they will do that as independent study in the day.When they go home they should enjoy quality family time.That has been really well received by parents who respect the fact that family time will be family time.But the school would still expect youngsters to study at home ahead of important exams.
     Independent learning at school would ensure equality because kids who get help with homework from parents might rely on others too much.
     Peter Devonish.a teacher at the school,said,"Having the children at school a bit longer to strengthen their learning is a really good idea,because they can have their time with the family."But he warned."A disadvantage is that our school is in the countryside,which means it's not so perfect to get children home at that time."
     Mr.Devonish said they also set pupils project-based homework,such as looking at an energy-efficient house,which allowed them to combine independent study with working with their parents.
     Craig Morrison,another teacher,said,"A large problem with homework has been that not enough is done with it.With homework.a lot of effort can go into it,so it's about celebrating what children do rather than processing it in terms of marking it and handing it back."
56.How will students spend their longer days at school?C
A.They will prepare their lessons for exams.
B.They will do homework with their teachers.
C.They will study all by themselves.
D.They will do homework on computers.
57.Why is the new idea well accepted by some parents?B
A.Because it helps kids with their homework.
B.Because kids will enjoy quality family time.
C.Because kids will be educated equally at school.
D.Because it can make houses more energy-efficient.
58.What is Mr.Devonish worried about?D
A.The students may dislike the idea.
B.No staff will agree to stay until 5:30 p.m.
C.More teachers will be needed.
D.The students may get home late.
59.According to Mr.Morrison,the'problem with homework isA.
A.what effort children make to do it
B.how teachers mark it and return it
C.how much homework should be set
D.that parents may object to the plan
60.The passage is mainly aboutB.
A.teachers who are asked to stay at school longer
B.a school where children stay longer for homework
C.homework which students have to deal with
D.students who like quality school time with teachers.
