一、 use作名词时,其发音为[ju:s]。它既可以作可数名词,也可以作不可数名词,意为"用处、用法、使用、利用"等。如:
A fridge has many uses.冰箱有许多用处。
The teacher' desk is for the use of teacher.讲桌是供老师用的。
二、 use作动词时,其发音为[ju:z]。一般作及物动词,意为"使用、利用、消耗、用 掉"等。如:
Use your head, then you'll find a way.动动脑筋,你就会想出办法来。
How much paper did you use last term?上学期你们用了多少纸张?
三、 be used to 的主语是人时,其意为"习惯于";be used to 的主语不是人而是物时,则为被动语态,意为"被用于"。如:He has been used to living in the city.他已经在城市里住惯了。
Knives are used to cut things.刀被用来切东西。
四、1)use作动词,意为“用、使用、利用”。use用作名词时,意思是“用途、用处”。其形容词为useful,意为“有用的”。如:Use your eyes to look and don't use your hands to touch.用眼睛看而不要用手摸。
What's the use of the bike﹖自行车有什么用途?Is the TV very useful﹖电视很有用吗?
If this book is not in use, I’d like to borrow it.如果这本书现在不用,我想借一下。
2) 句子中的up and down为副词词组,做状语,修饰动词go,表示“上上下下”、“来回地”、“到处”。 如:He looks at them an up and down.他将那人上上下下打量了一番。
He walks up and down in the classroom.他在教室里走来走去。
