一、语法专项
1. 一般过去时的被动语态学习三要素：
一般过去时的被动语态表示过去某一时间的被动动作或过去经常性、习惯性的被动动作，由“主语 + was / were + 及物动词的过去分词 + by + 动作执行者”构成，无需说明动作执行者时可省去“by + 动作执行者”。句中主语就是原主动语态的宾语，动作执行者就是原主动语态的主语。was, were的使用由主语的单复数形式而定，主语为第三人称单数名词、代词或I时用was, 主语为复数名词、代词they或you时用were。如：
This bridge was built in October last year.
These cakes were made by my mother last night.
2. 一般过去时的被动语态句型的变换方法
一般过去时被动语态句型变换应围绕was, were进行，否定形式应在其后加not, 一般疑问句形式应将其提至句首，特殊疑问句形式应将一般疑问句置于特殊疑问词后面，反意疑问句形式应保留was / were。
His computer was not stolen by thieves last night.
Was your homework finished in time yesterday evening
When was your letter written The day before yesterday
Your bike was not repaired last night, was it
3. 一般过去时的被动语态疑问句的回答方法
一般过去时的被动语态的一般疑问句形式肯定回答用“Yes, ... was / were.”，否定回答用“No, ... wasn’t / weren’t.”; 特殊疑问句应抓住特殊疑问词进行回答，可用简略方法，也可用完整方法; 反意疑问句也应用“Yes, ... was / were.”或“No, ... wasn’t / weren’t.”进行回答。如：
—Was your office cleaned yesterday afternoon
—Yes, it was. / No, it wasn’t.
—Were your rooms painted again last week
—Yes, they were. / No, they weren’t.
—When was your brother sent to work in Beijing

Do You Know When Basketball was Invented
Basketball is a much-loved and active sport that is enjoyed by many for fun and exercise. It is over 100 years old and is played by more than 100 million people in over 200 countries. It is believed that the first basketball game in history was played on December 21, 1891. Then in 1936 in Berlin, it became an event at the Olympics.
Basketball was invented by a Canadian doctor named James Naismith, who was born in 1861. When he was a college teacher, he was asked to think of a game that could be played in the winter. Dr. Naismith created a game to be played inside on a hard floor. Dr. Naismith divided the men in his class into two teams and taught them to play his new game. Players on the same team must work together to get the ball in the other team’s basket. At the same time, they need to stop the competing team from getting the ball into their own basket.
Today, the popularity of basketball has risen around the world, with many young people dreaming of becoming famous players. In China, you can sometimes see people playing basketball in parks, schools and even factories. Basketball has not only become a popular sport to play, but it has also become a popular sport to watch. Although America’s NBA games are the most famous, the CBA games are becoming more popular in China. The number of foreign players, including Chinese players, in the NBA has increased. There are also more and more foreign players in the CBA. Many young people look up to these basketball heroes and want to become like them. These stars encourage young people to work hard to achieve their dreams.

二. 阅读理解
A few years ago，Masaru Ibuka，the head of Sony，was at a company planning a meeting.
Suddenly he had an idea.He stopped the meeting and asked everyone what would happen if Sony took away the recording function (功能) and speakers and sold headphones with a tape player instead.
Almost everyone thought he was silly.Still，Ibuka kept his idea and worked at it.The result，of course，turned out to be the successful Sony Walkman.Good ideas often start with a really silly question.Bill Bowerman was making breakfast one day.As he stood there making cakes for his son，he asked himself what would happen if he put rubber into his mold(模具)．Later，he tried it and the result was something like the bottom of most sports shoes we see today.Still，when he took his idea to several shoe companies，he was laughed at.In fact，every single company turned him down．Though rather disappointed，Bill Bowerman went on to form his own company，making NIKE sports shoes.
We know today，that each of these ideas caused a successful thing that has changed the way many of us live.The best questions are usually open ended and are often silly.Children aren't afraid to ask such questions，but adults usually are.Think how different the world might be if people never asked “silly” questions!
