AEIS考试关于词汇ON的用法

　　AEIS考试你都准备的怎么样了，平时有没有进行一些阅读训练，阅读量是必须要有的，写作时有些词性的不同表达含义，下面和小编一起来看看具体解析吧。

　　ON

　　在...上面

　　Now let’s talk about on as a preposition. For me, the word on means specific location. I am not talking about being surrounded by something. I am focusing on a more specific location.

　　现在我们来谈谈介词on。对我来说，on是指特定的位置。我不是说被什么东西包围着。我把重点放在一个更具体的位置上。

　　For example

　　例如

　　I am in my room, but I am on a chair.

　　我在房间里，但我坐在椅子上。

　　I have given you a more specific location to help you locate me.

　　我给了你一个更具体的位置来帮助你找到我。

　　Perhaps, you need to find keys that belong to someone. You ask them in English, Where are your keys? They will answer, The keys are on the table.

　　也许，你需要找到属于某人的钥匙。你用英语问他们，你的钥匙在哪里?他们会回答的，钥匙在桌子上。

　　If they were to answer you like this, The keys are in the living room. It might take you a little longer to find those keys, since it wasn’t so specific.

　　如果他们像这样回答你：钥匙就在客厅里。你可能要花更长的时间才能找到那些钥匙，因为回答不是那么的具体。

　　Here are some more examples:

　　下面是一些例子：

　　I am on the bed. (I am NOT under the covers or blankets).

　　我在床上。(我不在被子或毯子下面)。

　　Her office is on the third floor. (A specific location in the building).

　　她的办公室在三层。(建筑物中的特定位置)。

　　I often hear my students tell me, My workbook is on my house. In English, this means that they have thrown their workbook on top of their house, on the roof. Why did they do that?

　　我经常听到我的学生告诉我，我的工作手册在我的房子上。在英语中，这意味着他们把他们的练习本扔在房顶上。他们为什么要那样做?

　　Well, thankfully they did not throw it on their house. They meant to say, My workbook is at my house.

　　谢天谢地，他们没有把钱丢在房顶上。他们的意思是说，我的工作手册在我家里。

　　AT

　　在...

　　This brings me to the next preposition at. At means general location. If the place that you are talking about is big, like an airport, hotel or even your house (with many rooms and locations) then you should use at.

　　这就引出了下一个介词at。它指的是大体的位置。如果你所谈论的地方很大，比如机场，旅馆，甚至你的房子(有许多房间和地点)，那么你应该使用at。

　　This lets the listener know your general location.

　　这能让听众知道你的大体位置。

　　For example

　　例如

　　My wife calls and says, Where are you?.

　　我妻子打电话说，你在哪里?

　　I would answer, I am at home. (Or even I am home)

　　我会回答，我在家里。(甚至“我在家”这样回答也可以)

　　If she wanted to know more specifically, (for example, she is home and she can’t find me) she would say, Yes, but where in the house?

　　如果她想更具体地知道，比如说，她在家，却找不到我，她会说问：是的，但是在家里的哪块儿呢?

　　I would respond, I am in the kitchen.. The preposition in lets her know that I am surrounded by the kitchen and if she wants to find me, then she can go there.

　　我会回答：我在厨房里。介词in让她知道我在厨房里，如果她想找我，她就可以去那里。

　　We can use at for the following situations:

　　我们可以在下列情况下使用at：

　　They are at the beach. (This is a big location).

　　他们在海滩上。(这是个大地方)。

　　They are at the airport.

　　他们在机场。

　　I am at the hotel or conference.

　　我在旅馆或在开会。

　　Sara is at work. (This lets me know her general location).

　　萨拉在上班。(这让我知道她的大体位置)。

　　Someone is at the door. (There are many different places someone can stand while next to a door. Just move 1 cm and you are at a “new” location.

　　有人在门口。(在门旁边有许多不同的地方可以站着。)只要移动1厘米，你就站在一个“新”的位置。

　　Bob is at school. (You can go to this school and you will find Bob there).

　　鲍伯在上学。(你可以去这所学校，你会发现鲍伯在那里)。

　　Now, at can also be used for time. I argue that the position of the earth and the sun are at a general location (given the huge size of the two objects). This is just my way of simplifying the way to remember when to use the preposition at.

　　现在告诉你，AT也可以用在时间前。我认为地球和太阳同处于在一个大体的位置上(考虑到两个物体的巨大尺寸)。这正是我简化使用介词短语的方法。

　　You can still think of the definition for at as a general location for time.

　　你仍然可以把它定义为时间上的大体位置。

　　So, I have English class at 8am.

　　所以，我在8点上英语课。
