Interactive teaching method has been introduced into junior high school English teaching, which has innovated classroom teaching methods, brought more opportunities for junior high school students to explore independently, and created a knowledgeable and open English classroom. Students have become the real masters of the classroom. The new English curriculum standard for junior middle schools puts forward that English teaching should be geared to all students, keep the language learning asymptotic and continuous, form innovative consciousness, develop scientific spirit and cultivate positive emotional attitudes and values. However, in the current junior high school English teaching practice, there are still some problems in interactive teaching, and English teachers need to take measures to improve them. Therefore, in daily teaching, junior high school English teachers should change the traditional teaching methods, create an open English classroom and enhance the interaction between teachers and students. On the one hand, they should cultivate junior high school students listening, speaking, reading and writing abilities;on the other hand, they should exercise their English thinking and accomplishment so that junior high school students can express and use English skillfully in real life.展开更多

文摘Proton exchange membrane water electrolysis(PEMWE)is a favorable technology for producing highpurity hydrogen under high current density using intermittent renewable energy.The performance of PEMWE is largely determined by the oxygen evolution reaction(OER),a sluggish four-electron reaction with a high reaction barrier.Nowadays,iridium(Ir)-based catalysts are the catalysts of choice for OER due to their excellent activity and durability in acidic solution.However,its high price and unsatisfactory electrochemical performance severely restrict the PEMWE’s practical application.In this review,we initiate by introducing the current OER reaction mechanisms,namely adsorbate evolution mechanism and lattice oxygen mechanism,with degradation mechanisms discussed.Optimized strategies in the preparation of advanced Ir-based catalysts are further introduced,with merits and potential problems also discussed.The parameters that determine the performance of PEMWE are then introduced,with unsolved issues and related outlooks summarized in the end.
