河北省武安市第三中学2014届高考英语一轮复习 Unit5 Theme Parks学案 新人教版必修4

Unit 5 Theme Parks高考作文背诵Dear Editor, I’m a senior high school student, named Li Hua. Now it’s fashionable for many students to have iPads. Using an iPad, we can listen to music, download a lot of learning materials and read them on the screen. Apparently, it’s helpful to our study, especially to our English listening. Some students, however, bring their iPads to the classroom listening to music with earphones or even playing video games, which makes teachers and other students greatly annoyed. In my opinion, the classroom is a place for students to study in, and concentration is awfully needed for us. Therefore, we should make good use of iPads to help achieve academic success . Meanwhile, school should make a rule to guide the students to use iPads in a proper way. Yours sincerely, Li Hua单元知识必备1.various adj.不同的；各种各样的 a large and various country 一个多姿多彩的大国a variety of /varieties of/all sorts of/all types of 各种各样的（1）There are various colors to choose from. 有各种各样的颜色可供选择。(2)That sort of thing varies person from person.那种事因人而异。。(3) A variety of marine creatures live in the ocean.海洋中生活着各种各样的海洋生物。2. preserve vt. 保护，维护，保存(以免受破坏)；保留 n．保护preserve sb./sth. from sth.保护……免受……（1）The society was set up to preserve endangered species from extinction.成立这个协会是为了保护濒危物种不致灭绝。(2)No hunting is allowed in the preserve.在自然保护区内不许打猎。(3)He was anxious to preserve his reputation.他急于维护自己的名声。(4) Efforts to preserve the peace have failed.维护和平的努力失败了。（5）(humorous)Is he really 60?
