It is conducted by having questionnaires and interviews among 220 students and by analyzing the teaching materials. The findings to the study indicate that the main obstacles are caused from the following aspects： neglecting the importance of developing vocabulary in the advanced study; neglecting activating the students＇ directing sense and detecting sense to difficult words; low rate of word recurrence in the teaching materials; requiring distinguishing the shade of the difference between synonyms excessively and too meticulously; overemphasizing the ＂negative transfer＂ of mother tongue; and some other obstacles to the development of lexical competence.展开更多

How to objectively evaluate brain function after CPR is essential to the following treatment. Coma patients after CPR had been studied prospectively at the Neuro-Intensive Care Unit of Xuanwu Hospital since 2002. In this study, we focused on the topic of how to evaluate the severity of coma after CPR . Methods From April 2002 to November 2004, patients in coma 24 hours after CPR were monitored, the evaluation methods included Glasgow coma score （GCS） , brain stem reflection, and spinal reflection. Laboratory evaluation included electroencephalography （EEG）, brainstem auditory evoked potential （BAEP）, short latency somatosensory evoked potential （SLSEP）, and transcranial Doppler （TCD） .Results Twenty-four of 35 patients（68.57% ）were in deep coma. The GCS was 3 except for 2 patients;EEG was evaluated not less than grade Ⅳ except for 4 patients, BAEP was evaluated as grade Ⅲ except for 3 patients, and SLSEP was evaluated as grade Ⅲ except for 1 patient. Twenty-four patients died within 1 month and 11 of them （ 45. 83% ） were determined as brain death. Glasgow outcome score （GOS） was evaluated as grade Ⅰ. Eleven of the 35 patients survived and their consciousness changed from deep coma to coma vigil. EEG was evaluated as grade Ⅰ in 5 patients, BAEP and SLSEP were evaluated as grade Ⅰ in 3 patients, and GOS was all evaluated as grade Ⅱ among the 11 patients. Two patients（ 18.18% ）regained consciousness in 35 and 90 days after cardiopulmonary resuscitation and GOS was evaluated as grade Ⅳ and Ⅲ, respectively. Conclusion objectively Combined or continuous evaluation of clinical examinations and laboratory tests can accurately determine brain function after CPR.展开更多

In order to solve these problems, we need to establish the idea of “complex modernity” as an analytical framework for analyzing the challenges confronting China and as a methodology for charting the country＇s future direction. We should also set up a pattern of thought consistent with the idea of“complex modernity” so as to construct the core values of contemporary Chinese society.展开更多
