(时间:60分钟,满分:100分)
if 引导的条件状语从句
条件状语从句在复合句中表示主句动作发生的条件。if 意思是“如果,假如”,可用来引导条件状语从句。如:
If it does not rain tomorrow, we will go hiking. 如果明天不下雨,我们就去远足。
You will get good grades if you study hard. 如果你努力学习,就会取得好成绩。
注意:if 引导的条件状语从句可以位于主句之前,也可位于主句之后。如果从句在前,从句与主句之间要用逗号隔开。
◆ 在 if 引导的条件状语从句中,主句中的动词常用一般将来时,从句中的动词用一般现在时。如:
If you ask him, he will help you. 如果你请他(帮忙),他会帮你的。
They are going to have a picnic if they are free next Saturday.
如果下周六有空,他们就去野餐。
◆ 在 if 引导的条件状语从句中,主句也可以含有情态动词或是祈使句。如:
If it is fine tomorrow, we can go and fly kites.
如果明天天气好,我们可以去放风筝。
Don’t miss the programme if you like music. 如果你喜欢音乐,不要错过这个节目。
unless 引导的条件状语从句
我们还可以用 unless 来引导条件状语从句。如:
Unless he writes them down, he will forget things.
除非他把事情记下来,否则就会忘记。
We will not get there on time unless we leave earlier.
如果我们不早点离开,就不能准时到那里。
◆ unless 意思是“除非,如果不”,相当于 if ... not。如:
You will be late unless you leave at once. 如果你不马上走,你将会迟到。
= If you do not leave at once, you will be late.
◆ 在 unless 引导的条件状语从句中,主句中的动词常用一般将来时,从句中的动词用一般现在时。如:
Unless it rains, the game will be played. 除非下雨,否则比赛将照常进行。
◆ 同 if 引导的条件状语从句一样,在 unless 引导的条件状语从句中,主句也可以含有情态动词或是祈使句。如:
He cannot see clearly unless he wears glasses. 他不戴眼镜就看不清楚。
Don’t touch the machine unless the teacher allows you to.

【答案】If your smartphone supports sound control, you can control it without touching it.

38.Little Bob will go to sleep if his mother tells him a story. (同义句转换)
Little Bob won’t go to sleep ________ his mother ________ him a story.
【答案】 unless tells
【详解】句意:如果他的妈妈给他讲故事,小鲍勃就会睡觉。此处改为同义句,可改为“小鲍勃不肯睡觉,除非他的妈妈给他讲个故事”,“除非”翻译为unless;从句主语是his mother,时态遵循“主将从现”,用一般现在时,动词tell用第三人称单数tells。故填unless;tells。
39.If she doesn’t take the medicine, she will feel worse. (改为同义句)
_________ she takes the medicine, she _________ feel worse.
【答案】 Unless will
【详解】句意:如果她不吃药,她会感觉更糟。“Unless”相当于“if not”,即“如果不”或“除非”,引导条件状语从句,遵循“主将从现”原则,因此第二个空用一般将来时,will“将”,故填Unless;will。
40.We will not hold the party if our class teacher doesn’t come. (改为同义句)
We will not hold the party ________ our class teacher ________
【答案】 unless comes
【详解】句意:如果班主任不来,我们就不举行晚会了。原句使用 if…not “如果……不……”结构表示条件,改为同义句时,可以用unless“除非”来表达相同的否定条件,unless后跟肯定形式的动词,从句主语是单数名词,时态是一般现在时,所以谓语动词come变成comes。故填unless;comes。
