9AU2Grammar 宾语从句一、宾语从句的定义在复合句中充当宾语作用的从句叫做宾语从句。
宾语从句可以用作谓语动词的宾语，也可以用作介词的宾语。
二、宾语从句的连接词1.由陈述句转化而来的宾语从句：把“that+陈述句”这一结构放在宾语的位置即构成宾语从句。
例句：The boy believes （that）he will travel through space to other planets.2.由一般疑问句转化而来的宾语从句：把“whether/if+陈述句”这一结构放在宾语的位置即构成宾语从句。
例句：I wonder whether/if they will come to our party.3.由特殊疑问句转化而来的宾语从句：把特殊疑问句变成陈述句语序后放在宾语的位置即构成宾语从句。
例句：None of us knows where these new parts can be bought.三、宾语从句的语序在宾语从句的复合句中，从句部分不管是陈述句还是疑问句都必须采用陈述语序。
I hear (that) physics isn’t easy.I think (that) you will like this school soon.Can you tell me how I can get to zoo?Please tell me when we’ll have the meeting.[注意]which, who, what在句子中是可以做主语的I wonder who is Tom’s English teacher.I don’t know what can be avoided.四、宾语从句的时态1. 如果主句的时态是一般现在时，宾语从句该用什么时态就用什么时态。
I don’t think (that) you are right.Please tell us where he is.Can you tell me how I can get to the railway station?2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态（一般过去时，过去进行时，过去将来时，过去完成时）。

课时作业10：Grammar
GrammarⅠ.单句语法填空1．Could you tell me the reason you were late for your work yesterday?2．The car window got broken in the accident belongs to Mr Brown.3．This is the primary school both my brother and I stayed for six years.4．This is the little girl parents both got killed in the train accident last year.5．Mother always remembers the day I was born.6．Though it is reasonable for the director to educate his staff, I don’t like the way he spoke to them.7．This is the house my grandfather lived three years ago.8．The reason he explained at the meeting was not sound.9．I still remember the day on I first came to this school.10．We went through a period communications were very difficult in the rural areas.Ⅱ.阅读理解We all know some great people in our lives. So what makes them so great? Dr Kimbro, author of the book What Makes the Great Great, believes that being great depends on a promise of making dreams come true. He writes in his book, “All high achievers make choices, not excuses.” We all have a million excuses for the failure of something, but only some go on to achieve their goals in life.Here are some other important things that make great people great.If you wish to achieve greatness, you should be willing to work your butt off. As Margaret Thatcher puts it beautifully, “I do not know anyone who has got to the top without hard work. That is the recipe. It will not always get you to the top, but should get you pretty near.”Practice and you shall get there. We learn things by practicing, be it walking, dancing, or even brushing our teeth. We do these things again and again until we become good at them. Greatpeople practice like there’s no tomorrow.Your critics (批评者) do you the biggest favor. They fuel you to do better. Every great person has his or her critics, who think the worse about them and doubt their talent. “Criticism may not be agreeable, but it is necessary. It fulfils the same function as pain in the human body. It calls attention to an unhealthy state of things，” Winston Churchill once said.All great people have one thing in common. They all have been selfless in their services to others. That was their intention (意图) all along: to serve others and to help them overcome difficulties. As Martin Luther King said, “Not everybody can be famous but everybody can be great, because greatness is determined by service.”When the time comes, be ready to lead. That is what separates (区分) the weak from the strong. Great people are not just about talking. They actually jump in when the need appears.1．What does the author want to show by mentioning Margaret Thatcher’s words?A．Hard work is very important.B．Not everyone can get to the top.C．We should have the right method.D．Almost everyone around her works hard.2．What does Winston Churchill think of criticism?A．Unavoidable.B．Important.C．Disappointing. D．Annoying.3．What does the author think separates the weak from the strong?A．Accepting criticism.B．Being critics to others.C．Holding on to promises.D．Leading the weak when needed.Ⅲ.完形填空One of my favorite high school teachers was Mrs. Ide.
