The words if and weather can be tricky for some English learners, that is because they are sometimes interchangeable if and whether our words that connect two or more sentences or clauses.

if和weather這兩個詞對於一些英語學習者來說是很棘手的，那是因為它們有時可以互換if和whether我們連接兩個或多個句子或分句的單詞。

And sometimes both words can signal that there are two possibilities or choices for something.

而有時候這兩個詞也可以表示某件事情有兩種可能或選擇。

Other times these words are not interchangeable.

其他時候這些詞是不能互換的。

Today I will give you a few examples of when you must use weather and cannot use if we use the word weather before infinitive verbs.

今天我就給大家舉幾個例子，如果我們在不定式動詞前使用天氣這個詞，什麼時候必須使用，什麼時候不能使用。

In American English, the infinitive means to plus verb.

在美國英語中，不定式的意思是加動詞。

Let's look at an example.

我們來看一個例子。

Listen for the infinitive verb after weather.

聽聽天氣後的不定式動詞。

I am wondering whether to get a book or magazine the infinitive following.

我想知道是要買書還是雜誌的不定式以下。

Whether is to get notice that the two possibilities here are a book or a magazine.

是否是得到通知，這裡的兩種可能是一本書或一本雜誌。

Notice also that the speaker did not say I am wondering if to get a book or a magazine.

還請注意，說話人沒有說我在想是要買書還是買雜誌。

Next up are Prepa Szish ins.

接下來是Prepa Szish保險。

We use the word weather after prepossessing ins.

我們用天氣這個詞，是在預設ins之後。

In this next example, pay attention for the prepossessing in and the word weather, which comes after it.

在接下來的這個例子中，要注意在和後面的天氣這個詞的前置性。

Teachers are interested in whether schools will reopen soon.

老師們都很關心學校是否會很快重新開學。

Here, the Prepa Szish in in comes before whether the two possibilities are that the schools will reopen soon or they won't notice that the speaker did not say teachers are interested in if schools will reopen soon, and that's everyday grammar.

在這裡，Prepa Szish in in 前面有兩種可能，一是學校很快會重新開學，二是他們不會注意到，說話人沒有說老師對學校是否會很快重新開學感興趣，這是日常文法。
