How do you prefer English classes to be taught，in English only，or in both English and Chinese？
I prefer my English classes to be taught in English only．As we know，a good learning environment is vital if we want to study English well．（高分句型一）Classes taught in English provide students with such an environment．When Englishis the only language used in the classroom，students will have more opportunities to practice listening and speaking．Therefore，they will be able to learn more quickly．
However，there are also some problems with this teaching method．As we haven't mastered enough English words，sometimes we may find it difficult to follow the teacher．（高分句型二）Slow learners may even lose interest in English．
Practice makes perfect．To learn English well requires a lot of practice．Therefore，Ilike my English classes to be taught completely in English．
Or：
How do you prefer English classes to be taught？in English only，or in both English and Chinese？
I prefer my English classes to be taught in both Chinese and English．In my opinion，learning English is a step-by-step process．As middle school students，we only have a small vocabulary．If the teacher can use some Chinesein an English class，we will underst and the lesson better． （高分句型三）
Of course，an English class taught in two languages has its shortcomings．Such a class cannot create a good atmosphere for English learning．Some students will speak Chinese all the time and cannot learn English well．
If you want to learn a lesson well，you have to understand it first．To help students understand the lesson better，the teacher should use Chinese from time to time．（高分句型四）Therefore，Ilike my teacher to use both English and Chinese in teaching．．
