Grammar and usage
LEAD-IN
Translate the following sentences into English!
要是你在10分钟前进入聊天室的话,你就知道我们在谈些什么了.
如果我在英国结婚,我会得到客人的礼物.
如果你来到了文莱,你进别人家门之前的脱鞋.
Here lie the questions:
Is it possible for the speaker to get married in the UK at the time when he or she says the first sentence?
In the second sentence, were “you” in the chat room ten minutes ago?
What has been said in these sentences is unreal and the verb forms like these can be called the subjunctive mood.
What is “mood” and how is mood used in English? First, please come to the introduction.
语气(mood)是一种动词形式，用以表示说话者的意图或态度。
在英语中随着说话人意图的不同，动词需用不同的形式，称为语气。英语语气有三种:陈述语气、祈使语气和虚拟语气。
虚拟语气，作为日常交际应用中常常会出现的一种语言现象，一直是高考题几乎年年都要考到的一个热点。但对于中国学生来说，它又是一个难点。无怪乎许多学生学习虚拟语气时，常常会叹道：If there were no subjunctive mood, English ______ much easier.
A. will be B. would have been C. could have been D. would be
But if you put your hearts into the our study in this class, you’ll find it very easy.
So what is the Subjunctive Mood? Just now we have mentoned the definition. But what is the key point in it?
考点与难点
本节课中将主要学习的内容
Now first we will come to the Subjunctive Mood used in the Unreal Conditionals.
Unreal conditionals state a condition or situation that is not real or is imaginary.
We use unreal conditionals to state a present condition or situation that is not real or is imaginary. As we have just mentioned in the sentence:
If I got married in the UK, I would expect a present.
Can you guess in which way the unreal present conditionals is formed?
Translate the sentences.
Do you like QQ games? Have you ever played the games? If you are addicted to the games, what will happen to your studies? What would happen if you were not addicted to QQ game?
Another question: have you ever bought a lottery ticket? Have you ever dreamt of winning a lottery? So What would you do if you won the lottery? Hare are two pictures for you to make uo the sentences.
That is the Subjunctive Mood used in the present unreall conditionals. We also use unreal conditionals to refer to an imaginary past action, as is mentioned in the sentece.
How is the unreal past conditionals formed?
Translate the two sentences.
Now more exercises for you. Please use these two pictures to complete the sentence.
We know Tom has his own car. But yesterday, just look at the picture. Please the following sentence.
We use unreal future conditionals to talk about imaginary future situations.
Here are three sentences. Please put them into English and pay attention to the verb forms.
So how is unreal future conditionals formed?
Some more practices.
Please use this situation to make up a sentence using the Subjuctive Mood in unreal future conditionals.
So far we have learned the three basic sentence structures of the Subjunctive Mood. Let’s have an overview.
There are still some points we must pay attention to.(tips)
1)Would, could and might are often interchangeable, but with some differences in meaning.
2) In written English or in formal situation, we usually use were in If-clauses in place of was. However, in everyday conversation, was is often used.
We can also put should, were and had at the beginning of an unreal conditional sentence. In this case, if is not needed any more.
Please rewrite the following sentences using inversion.
There is one important point. 如果省略的条件句中的谓语动词是否定形式时,不能用动词的缩略形式.
____ she ____ yesterday, she would meet the famous singer today.
Hadn’t; left B. Had; not left C.If; didn’t leave D. Didn’t; leave
In this sentence we should also pay attention to the time in both the clause and the main sentence.
当条件状语从句所表示的行为和主句表示的行为所发生的时间不一致时,被称为“错综时间条件句”。在这种情况下，我们切不可照搬某种形式，而应该按照句中所表述的时间关系，再选择相应的虚拟形式。
Some exercises.
