In today's lesson, we look at the difference between

在今天的課程裡，我們要探討的是「unless」

'unless' and 'as long as'.

和「as long as」間的差異。

Unless and 'as long as' can be used to replace 'if'

「unless」 和 「as long as」可以在不同的情況下

in different situations.

用來代替「if」。

Let's have a look at some example sentences:

讓我來看一些例句：

I will go to the party if you come too.

我會去那個派對，如果你也去的話。

I will go to the party as long as you come too.

我會去那個派對，假使你也去的話。

Both of these sentences have the same meaning.

這兩個句子的意思是一樣的。

Notice that the verb after 'if' and 'as long as' is positive.

請注意在「if」和「as long as」後面的動詞是肯定的。

Now look at these sentences:

現在來看一下這些例句：

If you don't do your homework, you can't watch the film.

如果你不做作業，你不能看電影。

Unless you do your homework, you can't watch the film.

除非你做好作業，要不然你不能看電影。

Both of these sentences have the same meaning.

這兩個句子的意思是一樣的。

But notice that the verb after 'if' is negative

不過請注意在「if」後面的動詞是否定的

and the verb after 'unless' is positive.

而在「unless」後面的動詞是肯定的。

Bye!

拜！
