反义疑问句

　　There be的反义疑问句一般是以be作为反义疑问部分的助动词来用，它也遵循“前肯后否、前否后肯”的原则。

　　There is a cup on the table, isn't there?

　　该句前半句为肯定句，所以反义疑问句部分要采用否定的isn't。

　　There is no juice left in the bottle, is there?

　　该句前半句为否定句，所以反义疑问句部分要采用肯定的is。

　　时态

　　there be句式的时态由其中的谓语动词be来体现，它可以有等多种时态形式：

　　■一般现在时

　　There is still room for improvement.还有改进余地。There is nothing to be done now.现在没有办法了。There is (some) milk in the fridge.冰箱里有一些牛奶。

　　■一般将来时

　　There’s going to be trouble.要出事了。There will be rain next week.下星期要下雨。There will be bloodshed tonight.今晚会发生流血事件。There is going to be [will be] an English film tonight.今晚将有一场英语电影。

　　■一般过去时

　　There was a lot to be done.有很多事要做。There wasn’t any change in him.他没有什么变化。There was a third reason for haste.匆忙行事还有第三个理由。There was nothing to fear from that quarter.那方面没有什么可怕的。There were some children swimming in the river.有些小孩在河里游泳。

　　■现在完成时

　　■过去将来时

　　情态动词的连用

　　There be句型也可以与情态动词连用。其基本用法结构为：There+情态动词+be+名词主语+其他成分。

　　There may be a great exhibition in Shanghai next year.There must be some cakes left in the box.There used to be a hospital there before the war.

　　各种句型中的There be

　　There be句型也可以和be going to 、seem to 、appear to 、used to、be likely to 、happen to等常用句型连用。其基本用法结构为：There+特殊句型+be+名词主语+其他成分。

　　There seem to be a big difference between the twins.There is going to be a film in the village tonight.There is likely to be a snowstorm.There happened to be a man nearby.There appeared to have been a tragic accident last week.

　　与其它动词的连用

　　There be结构中的be根据所表达的句意需要，有时会被替换为其他行为动词(come , live ,stand , lie,seem to be , happen to be 等)。

　　There came a breeze that his wife had eloped with her lover.有谣言说他妻子与她情人私奔了。Once upon a time, there lived a princess who was very beautiful.从前，有一位非常美丽的公主。There seems to be a knife and a forkon the table.

　　there be与have区别

　　1. there be句型表示某个时间或某个地方“存在”某人或某物;而have表示主语“拥有”某人或某物。have表示“有”的时候，主语一般是人。

　　I have a pen. 我有一支笔。I have long hair. 我有长头发。There be 一般指空间上的存在，There is a cup on the table.桌上有一个杯子。There are four students in the classroom.教室里有4个学生。

　　2. 第2个区别很明显，就是结构。There be句型在表示“有”的时候，是there be +sb/sth+时间/地点，Be要根据后面的sb.或sth来变换相应的形式，同时要注意到时态。

　　There was a meeting in this room yesterday.昨天这儿有个会议。(过去时)

　　而用have的时候，是sb./sth.+have+其他, have也要根据前面的主语和时态来变换相应形式。

　　He has two sons.他有两个儿子。I had a dream.我曾有个梦想。(过去时)

　　3.一般情况下，在表达“有”的时候二者不能随便替换。但也有用there be 和have都可以的情况，“当一句话前后两者的关系属于部分和整体的关系的时候”，两种表达都可以。

　　A week has seven days. =There are seven days in a week. 一个星期有七天。

　　(7 days和a week是部分与整体的关系)

　　4.there be句型在根据后面名词变化的时候，通常因为涉及到单复数变化，be要变成is或are。但如果涉及到后面的sth出现既有单数又有复数的情况，那么be动词的变化，遵循“就近原则”。说白了就是靠近be的那个sth是单数，be就变成is，是复数，就变成are.

　　There is an apple and some bananas on the table.如果先说“香蕉”，那么就是There are some bananas and one apple on the table.

　　There be的非谓语动词用法

　　There be 结构的非谓语动词形式是there to be 和there being 两种形式。在句中作主语、宾语和状语。

　　1、作主语

　　There being a bus stop near my house is a great advantage.我家旁边有个公共汽车站，很是方便。

　　2. 作宾语there to be可以用作expect、like、mean、intend、want、prefer等动词的复合宾语。

　　I expect there to be no argument about this. 我期望关于这件事不要再争吵了。)People don't want there to be another war.人们不希望再有战争了。

　　有时也会用作介词的宾语，其形式一般为there being。

　　I never dreamed of there being any good chance for me.我做梦也没想到我会有好机会。

　　3、作状语作状语时，通常采用“there being”结构。

　　There being no one to help me, I had to do it all alone.因为没有人帮助我，我不得不独立完成这项工作。
