知识梳理：
一、重点句型
【句型学习】
1. When was the telephone invented? 电话是什么时候发明的？
本句是一个特殊疑问句。was invented是一般过去时的被动语态形式。
一般过去时的被动语态构成形式为：was/ were +及物动词的过去分词。
The letter was posted yesterday. 信是昨天被寄出去的。
The books were borrowed last week. 这些书是上周被借的。
The novel __________ into several languages last year.
A. translate B. translated
C. was translated D. has translated
答案：C
思路分析：根据时间状语last year可判断时态用一般过去时。The novel是主语，动作的承受者，故用被动语态形式。选项C正确。句意为“这部小说去年被译成好几种语言”。
2. It is believed that tea was brought to Korea and Japan during the 6th and 7th centuries.
人们认为茶是在6到7世纪被传到韩国和日本去的。
it是形式主语，that引导的从句是真正的主语。It is believed …为常见句型，意为“人们认为……”，is believed 是被动语态形式，用在不知道动作believe的执行者或没有必要说出动作的执行者的情况下，也可改为 People believe that …。
It is believed that the farmers can get a good harvest this year. = People believe that the farmers can get a good harvest this year. 人们相信今年农民能有一个好收成。
It is said that… 据说……
It is supposed that… 据猜测……
It is said that there is a meeting tomorrow. 据说明天将有一个会议。
It is supposed that he is a singer. 人们猜测他是一位歌手。
It ____ that he can speak several foreign languages.
A. believes B. is believing C. is believed D. is to believe
答案：C
思路分析：It is believed…是固定句型，that 后是真正主语，it是形式主语，故选C项。句意为“人们相信他会说好几种语言”。
1. —________ that China has the largest number of mobile phone users.
—I believe so. It seems everyone has one.
A. Someone said B. They told me C. It is said D. I was told
2. The room _________ by Jack just now.
A. clean B. is cleaned C. cleaned D. was cleaned
答案：1～2 CD
思路分析：1. 所缺主句的时态要用一般现在时，和that从句的时态保持一致。句型It is said… 意为“据说”，其中it为形式主语，真正主语是that从句。
2. 根据时间状语just now可知时态用一般过去时；the room和clean之间是被动关系，故用一般过去时态的被动语态，故选D项。

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.

请根据以下提示，写一篇80～100词的短文。
汽车是世界上最重要的交通运输工具之一。它的发明极大地影响了人们的生活。过去人们常常靠马、骆驼等动物来旅行或运送货物，汽车同动物相比，不仅舒适快捷，而且使得同时运送大量的人员和货物成为可能。此外，汽车的发明还为人们提供了大量的就业机会。
生词提示：
1. 汽车：automobile 2. 货物： goods 3. 大量：large quantities of
Ⅰ. 1. D 解析：It is/was reported that+从句，意为“据报道……”，根据last week可知为过去的动作。所以选 D项。
2. C 解析：根据时间状语on April 20th，是过去的，要用过去时，又由主语是buildings，是动作的承受者，要用被动语态，所以要用过去时态的被动语态，选C项。
