Let's Do an ExperimentPPT，第三部分内容：Language points

1. Then I turn the jar upside down and take my hand off the cardboard.

然后，我把瓶子倒置，手离开纸片。

upside down 意思是“颠倒着，倒转着；乱七八糟”。 

e.g. The canoe floated upside down on the lake. 

独木舟底朝天漂浮在湖面上。

The children turned the house upside down. 

孩子们把屋里弄得乱七八糟。

turn… upside down 把……翻转；倒过来

e.g. If you turn the envelope upside down, the key will fall out. 

你如果把信封倒过来，钥匙就会掉出去。

take…off 把……拿开

e.g. Will you take your books off the table? 

把你的书从桌子上拿走好吗？

take away & take off

在take away 与take off 这两个短语中，take 都是“拿、带”的意思，away 和off 是副词，都可以表示“离开、离去”的意思。

从字面意思及结构看，这两个短语很容易被混淆。其实，这两个短语的意思和用法相差很远。

take away 可表示“拿走”、“使离开”、“减去”等意思。如：

His sister wants to take away this book.

他的姐姐想拿走这本书。

The girl was taken away from school.

女孩被带离学校。 

Take away 3 from 6 and you get 3.
