How to break them down? This paper will first point out and then analyze the obstacles that af fect middle school students'reading ability from two aspects:linguistic obstacles(obstacles of lexicon,grammar and background knowl edge) and non-linguistic obstacles(obstacles of psychology,interest,skill,and habit).After demonstrating different obstacles,the paper also come up with some corresponding strategies in the hope of helping middle school students to be effective English readers.展开更多

As Peter and Susan pointed in Teaching American English Pronunciation(1992), there are specific problem syllables with different language groups. As an ESL teacher from China, I assume it necessary to find out whether these sounds really trouble Chinese students in the ESL class I observed. I am going to pick out the most frequently occurred problem sounds and take notes how the teacher deal with them in class. In this paper, based on classroom observation and interviews, I analyzed problematic English vowels and consonants from Chinese learners, and the corresponding mediations for ESL teacher.展开更多
