题型:阅读理解 任务型读写。 China's College Entrance Examination (CEE)in 1977 and 1978 changed the fate of a group of Chinese people with large age differences and from all walks of life.Thirty years later, some of them anxiously wait outside exam spots, praying for good luck for their only child. The Chinese describe the CEE, or gaokao in Chinese, as "thousands of troops on a singlelog bridge" because of the limited number of places at universities.For students in the countryside, the tough exams may be their only opportunity to escape the hardship of country life. A survey conducted by the Ministry of Education and the China Youth Daily showed 89.6% of those people felt their fate was changed by the exam.Among those who said their fate was "totally changed", 69.1% came from the countryside and only 30.9% were from cities.Some Chinese think too much emphasis is placed on having a university diploma (文凭). It is believed that a person will not find a proper job without a college certificate, and that there are increasingly fewer jobs even for college graduates. Although the CEE is still a major means of selecting people for higher education after 30 years of development, the society has gradually adjusted its standard. A lot of people think that the CEE needs reforming, but these reforms will have to be gradual.While debates over the exam continue, more people believe it is the only open, fair and just way of talent selection.College Entrance Exam ShapesIntroduction◇The fate of a group of Chinese people with a large 1.________in their age and from all walks of life was changed by the CEE in 1977 and 1978.2.________of the CEE◇It is described as "thousands of troops on a singlelog bridge" because the number of places at universities is 3.________. ◇About eightynine percent of those people felt the exam changed their 4.________. ◇The CEE means more to those who come from the 5.________areas.Different opinions of the CEE◇Some Chinese think we 6.________having a university diploma too much.◇A lot of people think that the CEE needs to be 7. ________.◇We should carry out the reforms 8.________.Conclusion◇People continue 9.________over the exam.◇It is believed to be the only open, fair and just way of 10.________ talented people. 查看答案
