This paper focuses on the student- centered approach in English classroom teaching in vocational colleges. It points out that the students' English levels, the current mainstream of teaching in English class as well as the teaching materials in Chinese vocational college are all important factors that influence the outcome of the student-centered teaching approach. Meanwhile, the paper proves that college students can gain more in the student-centered English class. In the end, some suggestions are provided.展开更多

In order to change the teacher-centered teaching model into the student-centered one, Teachers should keep students' needs, interests, and learning styles in mind, apply several kinds of teaching techniques, organize different classroom activities and encourage, praise and appreciate both students' success and learning process all the time. If teachers place more responsibility in the hands of students, serve as "presenter or facilitator of knowledge" instead of "source of all knowledge", they can greatly motivate students to learn the language in a very active, cooperative and effective way. After all, people learn by doing, not only by watching and listening.展开更多

One of these γ-ray sources, the 10 TeV -γ-ray radiation reported by HESS, has been suggested as having a hadronic origin when relativistic protons are injected into and interact with the dense ambient gas. Assuming that such relativistic protons required by the hadronic model come from the tidal disruption of a star by the massive black hole of Sgr A＊, we explore the spectrum of the relativis- tic protons. In the calculations, we investigate cases where different types of stars are tidally disrupted by the black hole of Sgr A＊, and we consider that different diffusion mechanisms are used for the propagation of protons. The initial energy distribution of the injected spectrum of protons is assumed to follow a power-law with an exponential cut-off, and we derive the different indices of the injected spectra for the tidal disruption of different types of stars. For the best fit to the spectrum of photons detected by HESS, the spectral index of the injected relativistic protons is about 2.05 when a red giant is tidally disrupted by the black hole of Sgr A＊ and the diffusion mechanism is the Effective Confinement of Protons.展开更多
