人教版八年级英语上Unit10单元同步常见考点失误解析与自我检测
Unit 10 If you go to the party, you’ll have a great time!
1.如果明天天晴,我们将去野营。
误:If it will be fine tomorrow, we will go camping.
正:If it is fine tomorrow, we will go camping.
解析:if 意为“如果”,用作连词,引导条件状语从句。如果主句是一般将来时态,这时从句不可以用将来时态,而要用一般现在时。如:
I’ll do it if I have time this afternoon.
如果今天下午我有空的话,我将做这件事。
大多数情况下,从句可以位于主句之前,也可以位于主句之后。不过从句在前时,主从句之间必须用逗号隔开。例如:
Please tell me if he comes back.
= If he comes back, please tell me.
如果他回来了,请告诉我一声。
注意if的两面性:
if引导条件状语从句时意为“如果”,如果引导宾语从句则意为“是否”。请比较:
1) We will not go out if it snows tomorrow.
2) I don’t know if it will snow tomorrow.
句1) 中if引导的是状语从句。这个从句表示“条件”,整个句子的意思是“如果明天下雪好,我们不出去”。句2) 中if引导的是宾语从句,充当谓语动词don’t know的宾语,整个句子的意思是“我不知道明天是否下雪。”
[课文要点] What will happen if they have the party tomorrow? (P74)
2. 王老师对如何学习英语提出了许多好的建议。
误:Mr. Wang gave many good advices on how to study English.
正:Mr. Wang gave a lot of good advice on how to study English.
解析:advice “建议”,是不可数名词,“一条建议”,应该说a piece of advice,“许多建议”,应该说much(a lot of) advice。如:
He gave me a piece of advice.
他给我一句忠告。
Your English is pretty good. Can you give me some advice to me?
你英语很好。你能给我些建议吗?
[课文要点] Could you give me some advice please? (P75)
3. 你要不快点就会错过这趟班车。
误:You will miss the bus unless you don’t hurry up.
正:You will miss the bus unless you hurry up.
解析:unless是连词,意为“如果不”;“除非”,引导条件状语从句,本身表示否定意义,相当于if…not…,通常放在主句之后,若为加强语气,也可放在主句之前。如:
I will not go and play unless I finish my homework.
如果没有完成作业,我就不去玩。
Unless it rains, we shall work on the farm.
如果不下雨,我们将在农场劳动。
注意:unless引导的从句中用一般现在时代替一般将来时。
[课文要点] Unless we talk to someone, we’ll certainly feel worse. (P77)
