TWENTY-FIVEyears ago director Stephen Spielberg captured the hearts of Westen audiences with his family classic , E.T Now his Hong Kong dirctor Stephen Chow in trying to do the same trick in China,

Chow’s latest movie CJ7(《长江七号》),in cinemas now,is a heart-warming story about a poor migrant worker(外来务工者) and his son . When a strange alien enters their lives, father and son learn a lesson about the value of family , Chow hopes his movie will help to make family  films more popular in China.

Family films have been the main part of the Hollywood market for the last 40 years , They have given audiences movies like ET. Indiana Jones and Jurassic Park, However, there are few of  these movies in China , where expensive history films are more popular.

A family film is not simply a children’s movie , It is a film that is not only suitable for children,but appeals to the whole family.

According to Raymound Zhou , a famous film critic, these films are rare in China because “very few families go to the cinema together’. Because of this , there is little demand for  movise that appeal to the whole family,

However , in the West, it is common for the family to sit down and watch a movie together, Tim Bridges, from London, says :”I love it at Christmas when I sit down and watch a movie with my family.”

All family films contain similar messages about honest、remaining positive and learning there is more to life than money. According to the American movie reviewer, Dave Johnson, this is because “When parents watch a movie ,they wnt theier children to be learning good values”.

Just like when the alien in Spielberg’s E.T. phoens home to make contact with his family Chow will hope Chinese audiences are tuned in and ready to receive his family movie message.

63.Which of the following can replace the underlined part in the last paragraph

A understand what others are thinking    B make telephones

C go to the cinema    D sing songs

64. What is the family film. According to the passage?

A A kind of film that is about history

B A kind of film in which the charachers are animals

C A kind of film that is meant for both children and adults

D. A kind of film that is about families.

65.What is implied but not stated directly in the passage?

A  Families in Chian should go to the cinema at Christmas

B It’s good for children to watch family films

C Chinese families don’t like family films

D The movie CJ 7 has nothing in common with E.T.

66.It can be inferred that in the future,            

A Chinese families will go to the cinema  together

B there may be more family films in China

C making family films in China is not easy

D family films are about love

 

D

Japanese students work very hard but many are unhappy, They feel heavy pressures from their parents to do well in school, Most students are always being told by their parents to study harder so that they can have a wonderful life, Though this may be good ideas for those very bright students, it can have very bad results for many students who are not quick enough at learning

Unfortunately, a number of students killed themselves, Others are after comfort in using druges, Some do bad things with trouble-makers and turn to crime, Many of them have tried very hard at school but have failed in the exams and have disappointed their parents, Such students feel that they are les important and leave school before they have finished their study.

It is surprising that though most Japanese parents are worried about their children , they do not help them in any way, Many parents feel that they are not able to help their children and that it is the teachers’work to help their children, To make matters worse, a lot of parents send their children to special schools called juku-cram schools, These schools are open during the evening and on weekeds , and their only purpose is to prepare students to apss exams; they do not try to educate students in  any real sense of the real world, It thus comes as a shock to realize that almost three quarters of the junior or hight school population attend these cram schools,

Ordinary Japanese schools usually have rules about everything from the students’ hair to their clothes and things in their school bags. Child psychologists now think that such strick rules often lead to a feeling of being unsafe and being unable to fit into society, They regard the rules as being harmful to the development of each student, They believe that no sense of moral values is developed and that students are given neither guidance nor training in becoming good citizens

67. A lot of Japaness students are unhappy at school because          

A they work very hard    B they find they can’t do well at school

C they feel unimportant   D they are under too much prssure

68. Because fo their failure at school, some students take drugs to            

A kill themselves    B seek comfort

C disappoint their parents   D make trouble

69.What should be the best title of passage?

A Students’ Pressure    B Students’ Problems

C The Negative Impact(影响) of Japanese Education

D The Trouble in Japanese schools

70.In juku-cram schools students           

A are taken good care of by the teachers   B. feel no pressure

C are trained to pass exams   D can learn a lot of useful things

71.In ordinary Japanese schools,            

A there are strict rules    B, students feel safe

C students can do anything  D learning is not important

Dear Mr. Wang,

   We’re so pleased that you are willing to share our views.

   In the course of the general revision, what we need is solid foundation. As you know, we didn’t learn well enough in the first two years, so please slow down and make sure we have really mastered everything. Besides, we need a little more time to think for ourselves. As for those important points which also make us confused, would you please give us more practice in case we forget? Meanwhile, we need your instruction, for example, in how to write in natural English. I still have another request: assign us less homework in order that we can do it more efficiently.

    By the way, we often feel frustrated, which has a very bad effect on our study. We would appreciate it if you would give us some encouragement from time to time.

 

Yours
