Su Mei and Su Wen are talking about how to protect the sea. Read the dialogue and pay attention to the words in bold and the underlined nouns and noun phrases. Su Mei: The sea is very important to us. But there is more and more plastic pollution in the sea. What can we do to help protect the sea? Su Wen: There are many things we can do. We should organize a Beach Clean-Up Day. You see. there are always many bottles and plastic bags, and a lot of other rubbish on the beaches in our area. These things all end up in the sea. Su Mei: That's a good idea! Are there any other things we can do to help? Su Wen: Yes. of course. I will send you an article with some good suggestions. • We use there is with a singular noun or an uncountable noun. •We use there are with a plural noun. • there is - there's there is not = there isn't there are - there're there are not = there aren’t • Note the difference below: There are always many paper bags and a lot of plastic rubbish on the beaches. There is always a lot of plastic rubbish and many paper bags on the beaches. there be句型的结构和用法规则: 基本结构 There + is / are (名词+地点状语） 肯定句 There is +单数可数名词/不可数名词+地点状语 There is a book / some paper on the table. There are +复数可数名词+地点状语 There are three apples in the basket. 否定句 在be动词后加上not,缩略形式是isn't, aren't There isn't a book on the table. There aren't any apples in the basket. 一般疑问句 将be动词提到there前 Is there a book on the table? Are there any apples in the basket? there be句型的结构和用法规则: 轴殊疑问句 特殊疑问词（如 what, how many/much, who 等）+is /are there +其他成分 What’s there on the table? How many people are there in the room? 就近原则 当there be后有两个或更多的名词时，be动词的形式应与 最靠近它的名词在数上保持一致 There is a pen and two books on the table, （pen 是离 be 动词 最近的单数名词） There are two books and a pen on the table, （books 是离 be 动词最近的复数名词） there be和have的含义和用法不同，there be句型表达的是“在某个地方存在某人、某物等”， have/has则表示“某人拥有某物”。当主语为第三人称单数时，使用has；其他人称作主语，则使用have。 There are all kinds of books on my bookstore. 我的书柜上有各种各样的书。 I have all kinds of books. 我有各种各样的书。 There be 与have的区别 Jane: _______ pollution in the sea.
