Different types of questions can be designed to achieve different purposes in reading. While designing questions, teachers should take into consideration such points as the language used, manner of presentation and types of questions etc. Moreover, once questions have been designed, it’s essential for teachers to think about the techniques for the use of these questions. If appro- priately used, questions contribute greatly to students’ understanding of what they’ re reading by helping to explore the meaning that language conveys, in addition to developing proper reading skills. Therefore, teachers should be able to teach reading with well-designed questions so that the ultimate goal of understanding the text is likely to be achieved.展开更多

The pathogenic mechanisms underlying tobaccorelated cancers are well characterized and efective programs have led to a decline in smoking and related cancers, but there is a global epidemic of obesity without a clear understanding of how obesity causes cancer. Obesity is heterogeneous, and approximately 25% of obese individuals remain healthy(metabolically healthy obese, MHO), so which fat deposition(subcutaneous versus visceral, adipose versus ectopic) is "malignant"? What is the mechanism of carcinogenesis? Is it by metabolic dysregulation or chronic inflammation? Through which chemokines/genes/signaling pathways does adipose tissue influence carcinogenesis? Can selective inhibition of these pathways uncouple obesity from cancers? Do all obesity related cancers(ORCs) share a molecular signature? Are there common(overlapping) genetic loci that make individuals susceptible to obesity, metabolic syndrome, and cancers? Can we identify precursor lesions of ORCs and will early intervention of high risk individuals alter the natural history? It appears unlikely that the obesity epidemic will be controlled anytime soon; answers to these questions will help to reduce the adverse efect of obesity on human condition.展开更多

Fatigue can be caused by many factors such as physical and mental stress, disturbance in the circadian rhythm, and various diseases. For example, following the flu or other types of infections, everyone has experienced a sense of fatigue that can last for days or weeks. The fatigue sensation is thought to be one of the signals for the body to suppress physical activity in order to regain health. The mechanism of induction of the fatigue sensation following viral infection has not been well understood. Although fatigue was once thought to be caused by fever, our recent study with an animal model of viral infection demonstrated that the fatigue sensation is caused not by fever, but rather,展开更多

English teaching process is the process of"asking"and"answering"between teachers and students. Teachers should not only pay attention to the artistry of questioning, but also attach great importance to the strategy of asking questions. Appropriate teachers' questions are conducive to cultivate students' divergent thinking, and encourage students to better master knowledge by thinking and discussing, thus contributing to classroom interactions move towards a climax.展开更多

In language pedagogy, text-based questioning as both an attention drawing device and a form of learning tasks serves text instruction. Therefore, language teachers preparing text-based questioning should take into consideration all dimensions of questions, especially cognitive requirement and communicative character. In addition, interaction between learner, text and the world can be achieved by the adoption of both about-the-text and beyond-the-text questions in teachers＇ text-based question construction.展开更多

The aim of the study was to evaluate whether the results of an examination differ when short answer questions (SAQ) or modified essay questions (MEQ) are used. Method, Forty-nine students in the internal medicine course in Gothenburg, Sweden, performed a written examination in 2003, which included both SAQ and MEQ. Result, The correlation between the results of SAQ and MEQ was 0.59 (P < 0.001). The percentage correctly answered questions in the two types did not differ significantly. Some students had poor results in either SAQ or MEQ. Conclusion, The general outcome of the study indicates that results of SAQ and MEQ demonstrate a significant correlation. However, they may also reflect differences in mastery of the knowledge domain, which should be considered in relation to aspects of展开更多
