一变:肯定句变为否定句
技巧1.当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如:
I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
技巧2.当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如:
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如:
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.
二变:陈述句变为一般疑问句
技巧1.移动词语的位置。将was,were, could,would,should等移到句首。例如:
He could pack his things himself. → Could he pack his things himself?
技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时,在主语之前加did,动词还原。例如:
Mr Li looked very old. → Did Mr Li look very old?
三变:陈述句变为特殊疑问句
技巧1.确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如:
They gave the concert last night. → When did they give the concert?
技巧2.辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如:
The accident happened near the station. → Where did the accident happen?
考点名称:实义动词
- 实意动词:
即行为动词,表示动作的动词。实义动词与系动词是相对的,能独立用作谓语。
它分为及物动词和不及物动词两种:
及物动词是指后面要求有直接宾语的动词;
不及物动词指后面不需要跟宾语的动词。 实意动词使用方法:
及物动词
后面必须跟宾语意义才完整的实义动词,叫做及物动词(transitive verb)。如:
I believe that the committee will consider our suggestion.我相信委员会将会考虑我们的建议。
“How long can I keep the book ?”Harry asked.哈里问:“这本书我可以借多久?”
Dr. Bethune set us a good example. 白求恩大夫给我们树立了好榜样。
Crude oil contains many useful substances.原油含有许多有用的物质。
不及物动词
本身意义完整后面不须跟宾语的实义动词,叫做不及物动词(intransitive verb)。如:
Birds fly.鸟会飞。
It happened in June 1932.这件事发生于一九三二年六月。
My watch stopped.我的表停了。
She spoke at the meeting yesterday evening. 她在昨天晚上的会上发了言。
兼作及物动词和不及物动词
英语里有不少实义动词可以兼作及物动词和不及物动词。这样的动词又有两种不同的情况
a)兼作及物动词和不及物动词时,意义不变。试比较:
Shall I begin at once?我可以立刻开始吗?(begin作不及物动词)
She began working as a librarian after she left school.她毕业后当图书馆管理员。(began作及物动词)
When did they leave Chicago?他们是什么时候离开芝加哥的?(leave 作及物动词)
They left last week. 他们是上周离开的。(left 作不及物动词)
b)兼作及物动词和不及物动词时,有时意义不尽相同。如:
Wash your hands before meals.饭前要洗手。
Does this cloth wash well? 这布经得起洗吗?- 英汉实意动词用法比较:
与汉语的比较,有时英语动词的及物和不及物的用法,与汉语的用法不一样,请注意下列两种情况:
a)有的动词在英语里只能用作不及物动词,而汉语则可用作及物动词,如arrive到达,agree同意,listen听。英语里这些动词后面常接介词。如:
We arrived at the railway station at noon.
我们于中午到达火车站。(at不能省去)
(比较:We reached the railway station at noon.)
Everybody listened to the lecture with great interest.
每个人都很有兴趣地听讲课。(to不可省去)
(比较:We all heard the lecture.)
Do they agree to the plan?他们同意这个计划吗?(to不可省去)
b)有的动词在英语里能用作及物动词,而在汉语里则不能用作及物动词,如serve为…服务。
Our children are taught to serve the people wholeheartedly.
我们的儿童被教以全心全意为人民服务
用于be动词之后,实义动词之前。 实意动词的用法:
肯定句:
主语+动词过去式+其它
否定句:
主语+助动词didn‘t+动词原型+其他
一般过去式:
Did+主语+动词原型+其他
考点名称:助动词的过去式
- 助动词的过去式:
助动词
be
do
have
shall
will
过去式
was/were
did
had
should
would
考点名称:一般疑问句
- 一般疑问句:
是疑问句的一种。通常用yes,no来回答的疑问句叫做一般疑问句。口语中若无特殊含义,句末用升调。
其结构是:系动词be/助动词/情态动词+主语+其他成分?
通常回答为:
肯定:Yes+主语+提问的助动词
否定:No+主语+提问的助动词+not
例如:
Are you from Japan? Yes, I am./No, I'm not.
Do you live near your school? Yes, I do./No, I don't.
Can you speak French? Yes, I can./No, I can't. - 一般疑问句的特性:
