Jenny wants to do her homework on the computer. But her mum is using it.
Jenny: Mum, is it okay if I use the computer now
Mum: Okay. I just finished my work, so it's all yours. Jenny, you're so lucky to have a computer.
Jenny: Yes, I am. As it's connected to the internet, it has made study and research much easier.
Mum: This technology helps students a lot with their homework. But when I was a student, computers were not widely used. And the internet was not as convenient as it is now. I couldn't imagine having such a convenient tool for getting the job done.
Jenny: Mum, how was homework done in those days
Mum: Well, everything was written by hand on paper. When I didn't know how to spell a word, I had to look it up in a printed dictionary. When I needed to do any research, I had to go to the library.
Jenny: But now with the internet we can simply search for everything online. And there's always new technology, like AI.
Mum: Yes, and you can easily find definitions and examples for any word. The internet and the computer are amazing inventions with many applications.
Jenny: I agree with you on that, Mum.

一般过去时的被动语态——构成：was/ were+过去分词
（以动词 do 为例）
一般过去时 did was/ were+done The kite was made by him. 这只风筝是被他做成的。
时态 主动语态 被动语态 例句（被动语态）
一、单项选择
1．The windows ________ by Tom yesterday.
A．is broken B．broke C．were broken D．breaks
2．A sports meeting ________ in our school last month.
A．holds B．held C．is held D．was held
C
句意：昨天，这些窗户被汤姆打破了。
根据“yesterday”可知，使用一般过去时；主语“The windows”和“break”之间是被动关系，所以使用被动语态。句子用一般过去时的被动语态，应填were broken。
D
句意：上个月，我们学校举行了一场运动会。
holds举行，动词的第三人称单数；held举行/被举行，过去式/过去分词；is held被举行，一般现在时的被动；was held被举行，一般过去时的被动。根据“last month”可知，使用一般过去时；主语“A sports meeting”和“hold”之间是被动关系，所以使用被动语态；二者结合，应填was held。
3．—Why ________ you ________ to the class meeting yesterday
—Because I was ill and had to rest at home.
A．didn’t; inviteB．weren’t; invitedC．didn’t; invitedD．wasn’t; invited
4．The old house ________ in 1990.
A．was built B．is built C．will be built D．builds
B
句意：——昨天的班会为什么没有邀请你参加呢？ ——因为我生病了，所以不得不待在家里休息。根据“yesterday”可知，使用一般过去时；再根据答语“因为我生病了，所以不得不待在家里休息”可知，问句询问的是为什么“没被邀请”，所以使用被动语态，主语you为非三单形式，所以使用复数were；二者结合，应填weren’t; invited。
A
句意：这所老房子建于1990年 。
was built被建(build的一般过去时的被动语态)；is built被建(build的一般现在时的被动语态)；will be built将被建(build的一般将来时的被动语态)；builds建造(build的一般现在时的第三人称单数)。根据此句的主语“The old house”是动作的承受者，是被建造的，再根据此句的时间“in 1990”，过去的时间，因此此处需用“build”的一般过去时的被动语态“was built”。应填was built。
5．The sports meeting ________ because of the heavy rain, but the students ________ a wonderful indoor activity instead.
A．was not held; were given B．didn’t hold; gave C．was not held; gave D．didn’t hold; was given
6．Many trees ________ on the hill last spring.
A．planted B．were planted C．are planted D．plant
A
B
句意：因为大雨，运动会没有举行，不过学生们反而被提供了一次精彩的室内活动。
主语“The sports meeting”和“hold”之间是被动关系，应使用被动语态；第二个空所在的句子中，学生们是活动的接收者，而不是“给予”这个动作的发出者，使用被动语态，主语the students是复数，所以使用were。应填was not held; were given。
句意：去年春天，山上种了很多树。
planted栽种/被栽种，过去式/过去分词；were planted被栽种，一般过去时的被动；are planted被栽种，一般现在时的被动；plant栽种，动词原形。根据“last spring”可知，使用一般过去时；主语“Many trees”和“plant”之间是被动关系，所以使用被动语态；二者结合，应填were planted。
