A total of 120 participants participated in two rounds of essay composition and feedback delivery. The findings indicate that learners who receive comments in the form of questions are more prone to make revisions compared to those receiving statements or imperatives. These results hold significant implications for educators and the ways they utilize written feedback to enhance learners’ writing skills.展开更多

The U.S. side stated that it would no longer impose new tariffs on Chinese imports, sending a positive sign of the U.S.-China relationship to the international community. On July 3, the Washington Post published an open letter signed by 100 people from the academic, diplomatic, military, and business circles of the U.S. to President Trump and the U.S. Congress, affirming that the consensus is the intention of the two peoples and is in line with the expectations of the international community. The decline in U.S.- China relations is not in line with U.S. and global interests, and China is not an enemy of the U.S., nor does China pose a threat to U.S. national security.展开更多

Teachers are attempting to find out more effective methods to enhance the teaching results of English speaking. Facing the great demands and present difficulties of oral English classes, teachers have to conduct more study and practice to find out what roles that an oral English teacher has to take in the oral English classroom. Compared with the traditional teaching role in the English classroom, an oral English teacher has to fulfill more than one role in the classroom teaching so as to provide better learning conditions for students. Lacking more exposure to the real interaction with native speakers, students expect the oral English teacher to be a creator of the language environment. With various teaching and learning activities in the oral English classroom, the teacher has to be a good organizer to ensure every student to achieve improvement. An oral English teacher also has to correct students'language errors while ensuring the smooth progress of the classroom teaching. Only when an oral English teacher make clear what roles he or she has to take in the classroom can he or she achieve effective teaching.展开更多
