求翻译：学生在教师的引导下学习了新句型，新单词以后，还必须对所学的知识进行巩固。在没有对新句型，新单词等达到一定的熟练程度之前，学生很难将所学的知识应用到实际生活中去。因此，采用师生合作，生生合作，结合话题，围绕新知识点进行对话，交流和讨论等活动，让学生获得基本的语言能力。如在训练句型have to 时，我设计了三个训练程序。是什么意思？

Students in teacher learning under the guidance of a new sentence, after the new words, learned knowledge must also be consolidated. In the absence of new structures, new words before up to a certain level of proficiency, students is difficult to apply the knowledge learned to go in real life. Therefore, cooperation between teachers and students, students ' cooperation, combined with the topic, around a new dialogue between knowledge points, activities such as exchanges and discussions, students receive basic language ability. As in the training course is when you have to, I have designed three training programs.
