It lets us know the Internet may be a useful tool, but it has advantages and disadvantages. We should treat and use the Internet correctly and carefully, make our life more colourful.三. Analysis of students:The teaching object is just to the students of Grade Eight. The students have serious polarization phenomenon, they are lazy, and they can’t review and consolidate their learning contents in time.

I take different requirements for different students. 四．Teaching aims1.

Tell the students Internet can be a useful tool, but does it have disadvantages? Today we’ll learn Lesson23The Internet-Good or Bad? Then write the title on the blackboard.（The purpose of this design is to make the students naturally associate the new class that we want to talk about today, It can also stimulate the students’ desire for knowledge.)Step2.

(Learn the new words “advantage and disadvantages”and write them on the blackboard)2) Ask “What do you do on the Internet?” The students can answer: “study, chat, send or receive e-mails, watch TV or movies, listen to music, go shopping and search for information and so on”. Then the teacher summarizes the Internet connects us, it has changed the world. In many ways the Internet makes our life easy and simple. (Learn the new word “simple”, and write it on the blackboard)3) These are the advantages of the Internet. What are the disadvantages about the Internet? Can you say anything? The students can answer: “It may affect our study, It’s bad for our health, especially the eyes.”The teacher should encourage the students’ answer. And explain spending too much time online is harmful to people’s health, it may cause people to be less social with family and friends. (Show the pictures about the disadvantages of the Internet, write “be harmful to, cause, less” on the blackboard, help the students learn them.)4) The teacher supplements some other disadvantages of the Internet. (Show the pictures of well-known websites and online bank documents) and explain: Aside from that, some people attack the web or steal others’ personal information, even banking information, so we must use the internet properly, protect our personal and property safety. (Write “aside from, attack, web, steal, banking, properly” on the blackboard, help the students to learn them.)(I use the heuristic conversation method, The aim is to make the students learn the new words in a relaxing and happy environment.)Step3.
