There be 句型用法总结
There be 结构是英语中陈述事物客观存的常用句型，表示“有”，其确切含义是“存在”t here
作为引导词，本身没有意义，用动词be的某些形式作为谓语动词，它的主语是用一些表示泛指或不定特指的名词词组，动词be和
主语的数必须一致。句子最后通常为表示地点和时间的状语。因此要表达“某个地方或某个
时间存在什么事物或人”的时候常用“There be +
名词+ 地点（时间）这一句型。例如：
There is a great Italian deli across the street.
穿过街道，有一家大的意大利熟食店。
There are some students in the dormitory.
在宿舍里有一些学生。
一、There be 结构中的主谓一致
1.当动词be后所接的名词是单数可数名词或不可数名词时，be 应该取单数is；当其后所接的名词是复数的可数名词时，be用复数are。
There's a man at the door.
门口有个人。
There is some apple juice in the bottle.
瓶子里有些苹果汁。
There are some strangers in the street.
大街上有一些陌生人。
2.如果There be 后面是几个并列名词做主语时，动词be的形式和最靠近它的那个名词保持数的一致。
There is an ashtray and two bottles on the shelf. 架子上有一只烟灰缸和两个瓶子。There are two bottles and an ashtray on the shelf. 架子上有两个瓶子和一个烟灰缸。
二、There be 结构中的时态
1.There be 句型中动词be可以有一般现在时、一般过去时、将来时和完成时。
There is no harm in trying.
不妨一试。
There were fabulous wildflowers in the hills last spring.
去年春天，山中有极美的野花。
There will be a fine day tomorrow.
明天将是一个晴天。
There have been several private schools in our area this year.
今年，我们这里已经有好几所私立学校了。
2.There be 句型可以和各种助动词、情态动词连用。
There may be a cigarette in that box.
那只盒子里或许有支香烟。
There must be some cakes on the table.
桌子上一定有些蛋糕。
There used to be a hospital there before the war.
战前，那里曾经有家医院。
3.There be 句型也可以和这样一些的谓语动词连用：be going to 、seem to 、appear to 、used
to、be likely to 、happen to ….

在我与草坪之间好像有一些树。

Once upon a time there lived a king in China.
从前中国有一个国王。
三、There be 句型的否定句、一般疑问句、特殊疑问句和反意疑问句
1.There be 句型的否定句有两种构成方式，一种是将否定副词not放在be 之后，如：There isn’t a box in
the room.
房间里没有盒子。
There aren’t any pens on the desk.
课桌上没有钢笔。
2.There be 句型的一般疑问句是将be 放在there 之前，回答时用yes或no，后接简单答语。如：
Is there a cake on the table?
桌子上有块蛋糕吗？
Yes，there is. / No，there isn’t.
是，有。/ 不，没有。
Will there be a party tonight？
今晚有聚会吗？

4.There be 句型的反意疑问句

桌子上有只杯子，是吗？

四、There be 结构和have的区别与联系
1.区别点：there be 意为存在，强调某地有某物，不表示所属关系；have 表示所有关系，
强调某人或某地有某物，这是其基本用法。如：
There are some trees in front of the house.
房前有些树。
Tom has many friends in China.

2.相同点：在表示结构上的含有时，既可以用there be 句型，也可以用have （has）来表示。如：

?1 掌握情态动词can和must在本单元中的用法
1. can 的用法：
（1）.表示能力、许可、可能性。表示能力时一般译为“能、会”，即有种能力，尤其是生来具备的能力，此时may 和must 均不可代替它。如：She can swim fast, but I can’t . 她能游得很快，但我不能。I can see with my eyes. 我用眼睛看。
（2）.表示许可，常在口语中。如：You can use my dictionary. 你可以用我的字典。（3）.表示推测，意为“可能”，常用于否定句和疑问句中，此时can’t 译为“ 不可能”。如：Can the news be true? 这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们老师吗？—No, it can’t be our teacher. He is on a visit to th e Great Wall.不可能。咱们老师正在游览长城呢。
【例题】—I think Miss Gao must be in the library. She said she would go there. —No. She __be there, I have just been there. A.can’t B.mustn’t C.needn’t D.wouldn’t
【解析】根据下文“我刚去过那儿”可知，应为“ 不可能”，can’t 表示推测[答案] A 2. could的用法：
（1）.can的过去式，意为“ 能、会”，表示过去的能力。如：He could write poems when
he was 10. 他十岁时就会写诗。
（2）. could在疑问句中，表示委婉的语气，此时 could 没有过去式的意思。如:Could you do me a favour? 你能帮我个忙吗？—Could I use your pen? 我能用一下你的钢笔吗? —Yes, you can.可以。（注意回答）
3. may的用法：
（1）.表示请求、许可，比can 正式，如：May I borrow your bike? 我可以借你的自行车吗？You may go home now. 现在你可以回家了。
【例题】—_______ I borrow your MP3? —Sure . Here you are.
A. May
B.Should
C.Must
D. Would
(2) .表示推测，谈论可能性，意为“ 可能，或许”，一般用于肯定句中。如：It may rain tomorrow . 明天可能会下雨。She may be at home. 她可能在家呢.
(3) .may的过去式为might ，表示推测时。可能性低于may。如：He is away from school. He might be sick.
他离开学校了，可能是他生病了。
(4) . 表示希望、祈求、祝愿，常可译为“祝愿”。通常是用may +主+V 例如：May you have
a good time. 祝你过得愉快。 May you be happy! 祝你幸福！ May you succeed！祝你成功！
4. must的用法：
(1).must 表示主观看法，意为“必须、一定”。如：You must stay here until I come back.在我回来之前你必须呆在这儿。Must I hand in my homework right now? 我必须现在交作业吗？
(2) 其否定形式mustn’t表示“ 一定不要” “千万别” “禁止, 不许”. 如：You mustn’t play with fire. 你不许玩火。You mustn’t be late. 你一定不要迟到。（3）对must引导的疑问句，肯定回答为must，否定回答为needn’t 或don’t have to .如：—Must I finish my homework?我现在必须完成作业吗？—No, you needn’t.不，你不必。
(4)must表示有把握的推测，用于肯定句。如: The light is on, so he must be at home now.灯亮着，他现在肯定在家。
注意其反意问句的构成形式：
当must表示肯定的判断、推测时，其反意疑问句要用实际问句的助动词来构成。如：She must have seen the film before，hasn’t she?(注意反意疑问句的后半部分)You must have met uncle Wang in the shop yesterday，didn’t you? (注意反意疑问句的后半部分) 5. need的用法：
（1）.need 表示需要、必须，主要用于否定句和疑问句中，其否定形式为needn’t，意为“没有必要，不必”。用need 提问时，肯定回答为 must，否定回答为needn’t或don’t have to。如：—Need I stay here any longer? 我还有必要留在这儿吗？—Yes, you must .是的。—No. you needn’t /don’t have to. 不，你不必。
(2).need 还可以作实义动词，此时有人称、数和时态的变化，如果是人作主语后边多接动词不定式。如：I need to do it right now. 我需要马上做这件事。He needs to learn more about the girl.他需要多了解那个女孩。
如果是物作主语，一般用need doing 与 need to be done这种情况下应注意两点：
①.主动形式的动名词doing具有被动的含义；②.该动名词可以改为其动词不定式的被动形式而句子的意义不变。例如：. The door needs painting. = The door needs to be painted. 那扇门需要油漆一下。Your car needs mending. = Your car needs to be repaired. 你
的车需要维修了。
can’t 和 mustn’t
1. can’t 根据其基本用法可译为：
（1）不会。如：I can’t speak English . 我不会说英语。
（2）不能。如：We can’t do it now because it’s too dark.天太黑了，我们现在干不了。
（3）否定句中表示推测。“不可能”，如：The man can’t be our teacher because he is much younger than our teacher.. 那个人不可能是咱们老师，他年轻得多。
2. mustn’t 意为“ 禁止、不许”，用来表达命令，表示强烈的语气。如：You mustn’t play football in the street. It’s too dangerous.你不可以在街上踢足球，太危险了。易混点五：must 和 have to
1.must 侧重于个人意志和主观上的必要。have to 侧重于客观上的必要，可用于现在时、过去时和将来时。如：I know I must study hard.我知道我必须努力学习。My brother was very ill, so I had to call the doctor in the mid-night.我弟弟病得厉害，我只得半夜里把医生请来。I haven’t got any money with me, so I’ll have to borrow some from my friend.我身上没带钱，只好向朋友借点了。He said they must work hard.他说他们必须努力工作。
2. have to可以用于多种时态；而must只用于一般现在或将来。如：The composition is due to hand in this morning, so I had to finish it last night. 作文今天早晨到期，因此我不得不昨天晚上完成。
易混点六: used to do / be used to doing / be used to do…/ be used for doing sth used to do 表示过去常常发生的动作，强调过去，只用于过去，注意用 to do，不用doing 形式；而be used to doing 意为“习惯做…”， be 可有各种时态； be used to do 意为“……被使用去做……,”为被动语态形式。be used for doing sth“用作……”如：My father used to eating meat.我父亲过去起床晚，但现在不得不早起了。She is used to eating meat.她习惯吃肉。He wasn’t used to eating in a restaurant.他不习惯在饭店吃饭。A knife can be used for cutting things.(刀可以用来割东西)/ A knife can be used to cut things.(刀可以用来割东西)
