    区分宾语从句、定于从句和状语从句宾语从句和状语从句,都叫做主从复合句。宾语从句主要是中考必考的,是初中阶段必掌握的从句,宾语从句主要是掌握三要素,所谓宾语从句,就是宾语在主从复合句当中充当宾语的一个句子,叫做宾语从句。主句的谓语动词是及物动词,后面如果是词或者是短语的话,是简单句,如果是句子的话,肯定是宾语从句。I know that he good at English.就是宾语从句,三要素,一要素是要注意连词,连词一共学了三类连词,一类连词是that口语当中可以省略,就像刚才说的那一句,I hear he is good at English.还有疑问代词、疑问副词,how where when,疑问代词、疑问副词。还有一类连词weather是否的意思,不是状语从句当中的如果,这一定要和如果区分开,这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序,要用陈述举语序。比如说你家有几口人,我们都说How many people are there in you family?但是这是简单句,一旦说成宾语从句,你可以告诉我你家有几口人吗?Could you tell me how many people there are in you family ?

    "Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!欢迎你!请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢?“噢,不!”与陌生人谈话太困难了。但是这也很有意思,并且你还能交到朋友。你该怎么做呢?闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员,不是吗?”“我希望自己能认识她,你呢?“今年的雨水很多,不是吗?”反意疑问句是一种礼貌用语。为了使得谈话成功,你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧,下次在英语课上,你会发现与大家展开谈话是一件很容易的事情,不信我们来试试。)
