Unit 4 Grammar: Using there is / are Let's talk about our world! 1.7.2013 大家好,欢迎回来!今天我们要学习一个非常有用的语法点。它将帮助我们描述我们美丽的世界,比如海洋、公园,甚至是我们自己的教室。让我们开始吧! ‹#› What can you see? a bed 一张床 a desk 一张书桌 a chair 一把椅子 a computer 一台电脑 a lamp 一盏台灯 some books 一些书 a football 一个足球 a cat 一只猫 two pictures 两张画 three pens 三支笔 1.7.2013 看这个乱糟糟的房间!简直是一场灾难!你能告诉我你看到了什么吗?试着用简单的英语描述。比如,'I see a bed.' 或 'I see books.' 让我们分享一下你的发现。 ‹#› A Conversation about the Ocean Amy Look at this picture of the ocean. It's so beautiful! Jack Yes, it is. But there is a problem.There is a plastic bottle in the water. Amy Oh no! And look! There are many plastic bags on the beach. Jack You're right.There area lot of sea animals living here. We must protect them. Amy Yes, we should keep our oceans clean. 1.7.2013 现在,让我们来读一段艾米和杰克之间的简短对话。他们正在谈论海洋。请和你的搭档一起大声朗读。注意蓝色的句子,你发现它们有什么相似之处吗?它们似乎有一个相似的结构。今天,我们将学习如何使用这个结构来描述某个地方存在什么。 ‹#› Grammar Focus 1:there is 核心规则 / Core Rules There isis used to talk aboutonething (singular noun) or something we cannot count (uncountable noun). Structure 1:There is+ a/an + singular noun. Structure 2:There is+ uncountable noun. 经典例句 / Examples There is a book on the desk. There is an apple in the bag. There is some water in the glass. There is a lot of sand on the beach. 1.7.2013 观察得非常好!这个结构就是 'There is' 或 'There are'。我们先从 'There is' 开始。当我们谈论一个事物时,我们用 'There is'。例如,'There is a book.' 'a book' 是一个事物。我们也用它来形容我们数不清的东西,比如水或沙子。我们来看例子。 ‹#› Practice 1: Make sentences with `there is` 01 Look at the picture carefully _a book and an apple on the desk. 02 Observe the details in the scene _some water in the glass and some sand in the hourglass. 1.7.2013 现在轮到你们了!看这些图片,用 'There is' 完成句子。你可以和你的搭档一起讨论。我给你们两分钟时间。 ‹#› Grammar Focus 2: `there are` 核心规则 / Core Rules `There are`is used to talk aboutmore than one thing (plural noun). It refers to the existence of multiple objects. Structure Formula: There are+ [a/an/some/many...] +Plural Noun+ (Place/Time). Pro Tip: Always check if the noun is singular or plural! 例句 / Examples There are three books on the wooden desk in my room. There are many excited students in the bright classroom. There are some colorful birds singing in the tall tree. There are a lot of people enjoying the sun on the beach. 1.7.2013 如果我们有不止一个事物呢?我们用 'There are'。例如,'There are three books.' 'three books' 是复数。我们来看这些例子。 ‹#› Practice 2: Make sentences with `there are` Look & Fill in the Blanks Q1: Look at the books on the desk. _ three books on the desk. Q2: Look at the students in the class. _ many students in the classroom. 1.7.2013 太棒了!现在我们来练习使用 'There are'。看图片并完成句子。记住,我们对复数名词使用 'There are'。我们一起来做。 ‹#› Grammar Focus 3: Contractions (缩略形式) In spoken English, we often use contractions to make it easier and faster. Singular Form (单数) There is There's Example:There’s a cute cat sleeping on the warm roof. Plural Form (复数) There are There're Example:There’re so many bright stars shining in the night sky. 1.7.2013 当我们说话时,我们经常把 'There is' 和 'There are' 说得更短。'There is' 变成 'There's'。'There are' 变成 'There're'。在对话中这样说更自然。我们来练习说一下。 ‹#› Practice 3: Fill in the blanks with `there's` or `there are` 01 _a new student in our class. 02 _two new students in our class. 03 _some milk in the fridge. 04 _a lot of people at the party. 05 _a pen and two books on the table. 1.7.2013 我们来做一个快速练习。用正确的缩略形式填空。注意后面的名词。 ‹#› Grammar Focus 4: Using `a lot of` Core Rule `a lot of` means "many" or "much". It can be used with both plural countable nouns and uncountable nouns. Structure: There is + a lot of + [Uncountable Noun] Example: There isa lot ofwater in the ocean. Structure: There are + a lot of + [Plural Noun] Example: There are a lot of fish in the ocean. 1.7.2013 我们如何用 'there is/are' 来表达 'many' 或 'much' 呢?我们可以用 'a lot of'。 看例子,'water' 是不可数的,所以我们用 'There is a lot of water'。 'fish' 是可数的,所以我们用 'There are a lot of fish'。 'a lot of' 非常有用! ‹#› Practice 4: Choose `is` or `are` 01 There _ a lot of sand on the beach. Options:is/are 02 There _ a lot of people at the beach. Options:is/are 03 There _ a lot of noise in the city. Options:is/are 04 There _ a lot of cars on the road. Options:is/are 05 There _ a lot of information online. Options:is/are TIP:Check the noun after 'a lot of'. Is it Singular/Uncountable or Plural? 1.7.2013 这是一个常见的考点!记住,在 'a lot of' 之后,你需要检查名词。它是单数/不可数还是复数?让我们为每个句子选择正确的动词。 ‹#› Practice 5: Look and Write (Part 1) TASK:Look at the trash cans. What's inside?
