方位介词： on, in 和 under　　这三个介词都是用来指示位置关系的介词，与后面表示地点的宾语

构成介词短语，表明两个对象的位置关系，所以我们形象地称之为方位介词。

The backpack is on the table.

The books are on the chair.

The dog isn’t on the floor.It’s on the sofa.

你还能用 on说出几个类似的句子吗？

on 的意思为 “在……的上面”，所提到的两个对象有一定的接触面。

方位介词： on, in 和 underin 意为 “在……里面”，所提到的两个对象在位置上有相对的包含关系。

The three bottles are in the box.

The water is in the teapot.

under 意为“在……下面”，所提到的两个对象没有接触面。

The football is under the table.

The keys are under the bed.

Grammar focus　　 where 是一个疑问副词，意为“在哪儿”，常常用来提问地点。在英语中，提问某人或某物在哪儿的句型为“ where + is / are + 主语”，如果句子的主语是可数名词的单数形式或不可数名词，用 is ，如果主语是可数名词的复数形式，用 are 。这类句子的答语往往是“ It is / They are + 方位介词＋名词或代词”。如：　　 --- Where is the computer? 计算机在哪儿？ --- It’s on the desk. 它在桌子上。　　 --- Where is your English book? 你的英语书在哪儿？ --- It’s in my school bag. 它在我的书包里。　　 --- Where are his keys? 他的钥匙在哪儿？ --- They are on the dresser. 它们在梳妆台上。　　 ---Where are my shoes? 我的鞋在哪儿？　　 --- They are under your bed. 在你的床底下。

道”。当你对他人提出的问题或询问一无所知时，可以用这句话来回答，在日常交际中，为了显得有礼貌，还可以在前面加上“ sorry” 来表示歉意。如：

　 --- Where are my books? --- Sorry, I don’t know.2. “Are they on the bed?” 是一个一般疑问句，意为“它们

在床上吗？”，这种问句的肯定答语用“ yes”, 否定答语用 “ no” 。如：

　　 --- Is your bag on your bed? --- Yes, it is. --- Are the pencils in the pencil case? --- No, they aren’t.

Where is my bag? Is it on your desk?

Put them into the right places

Help on line1. Please take these things to you brother. 请把这些东西带给你哥哥。　 句中的“ take” 是一个动词，意为“拿走；带到”。 to 是介

词，表示方向。 take…to… 意为“把……带到……去”。如：

　 Please take the books to your classroom. 请把这些书带到你的教室去。2. Can you bring some things to school? 你能把一些东西带到学校来吗？　 bring 也是一个动词，意为“带来；拿来”，它所表示的方

向正好与 take 相反。它也常与介词 to 连用，意为“把……带到……来”。如：

　 Please bring your English books to school. 请把你们的英语书带到学校里来。

Help on line　 can 是一个情态动词，意为“能”，可用于任何的人称之后，不管句子的主语是什么人称， can 后的动词一律用原形。“ Can you …?” 是一个征求对方许可的句型，意为“你能……怎样吗？”，在语气上显得很有礼貌。如：

　 Can you help me read the words. 你能帮我读记读这些单词吗？3. I need my hat, my notebook and a pen. 我需要我的帽子、笔记本和一支钢笔。　 句中 need 用作动词，意为“需要”，它的后面可以直接

跟名词或代词作宾语。如：　 We need a pencil case. 我们需要一个钢笔盒。　 I need your help. 我需要你的帮助。

I need a hat.

1. － ______ my computer game? － ______ in the drawer. A. How’s; It’s B. Where’s; It’s C. Where’re; They’re 解析：答语中“ in the drawer” 意为”在抽屉里“，是一个表示在点的介词　短语。由此可推断前面询问的是地点，应使用 where 进行询问。句子的　主语 computer game 是单数形式，所以系动词用 is, 与之相对应的代词　是 it 。　答案： B

2. － Can you ______ her video cassette here? － OK. A. take B. bring C. need 解析： take 意为”带走“，在方向上由近及远。 bring 意为“带来”，在方向　由远及近。 need 意为“需要”。 here 意为“这儿”，由对话的情景可以看出，　是强调把录象带（由远处）带到这儿来。　答案： B

Try 3. － Where is my CD? － I ______ know. A. not B. am not C. don’t 解析： know 是一个实义动词，意为”知道“，句子的主语是 I ，构成否定　时用助动词 do 的否定形式 don’t 。其实 I don’t know. 是口语交际中常用的　一个短句，意为”我不知道。“。　答案： C4. － ______ you answer the questions? － Sorry, I can’t. A. Can B. Are C. Do 解析： answer 是一个实义动词，在构成疑问时不能在前面加系动词，可 排除 B 项。 can 与 do 都可以构成疑问，但句子在意思上不一样， can 是一 情态动词，意为”能“，在构成疑问时可以表示请求。 do 则没有这样的功 能，它只是一个助动词，没有意思。再者，句子的答语是” Sorry, I can’t”, 从这个答语上也能做出判断。 答案： A
