如： Do you have any other question(s)? 你还有其他问题吗？

Ask some other people. 问问别人吧！

2.the other指两个人或物中的一个时，只能用the other，不能用another，此时的other作代词。如： He has two daughters. One is a nurse, the other is a worker. 他有两个女儿，一个是护士，另一个是工人。 the other后可加单数名词，也可加复数名词，此时的other作形容词。如： On the other side of the street，there is a tall tree. 在街道的另一边，有一棵大树。

4.the others意思是“其他东西，其余的人”。特指某一范围内的“其他的（人或物）”。是the other的复数形式。如： Two boys will go to the zoo, and the others will stay at home. 两个男孩将去动物园，其余的留在家里。 the others=the other 复数名词 5.

another，既可作形容词，也可作代词，只能用于三个或更多的人或物，泛指同类事物中的三者或三者以上的“另一个”，只能代替或修饰单数可数名词。

如： I don’t like this one. Please show me another. 我不喜欢这一个，请给我看看另一个。

。

（二）join的用法

1. 加入某党派、组织、俱乐部等

例句：I joined the Party two years ago. 2. 当与一段时间连用时，将其变为be a number of

例句：I joined the Party two years ago.

= I have been a number of the Party for two years. 3. join in = take part in

参加某项活动

4. join sb 加入某人的行列

（三）unless的用法

unless是从属连词，引导条件状语从句，含有否定意义，相当于if条件状语从句的否定形式。所以unless = if not。

注意：unless引导的条件状语从句和if条件状语从句，与其它时间状语从句一样，用一般现在时代替将来时。

unless在意义上相当于if...not，因此在有些场合中unless与if...not可
