unit2宾语从句

渔民想知道天是否会下雨。
Ⅱ. if和whether引导宾语从句时，要注意宾语 从句三要素，即连词、语序和时态。由于if和 whether连接的是一般疑问句，因此要注意把 从句语序改为陈述句语序。如： Does Mr Zhao live in Room 208? Could you tell me? →Could you tell me if/whether Mr Zhao lives in Room 208?
注：that 在句中无词汇意义，在从句中不充 当成分，在口语当中往往省略。 1. I hear (that) _______________________. he will be back in an hour 2. He said (that) ______________________. he missed us very much the earth moves 3. The teacher told us (that) _______________ around the sun ________________.
3. that从句中含有主从复合句。如：
I’m afraid that if you’ve lost it, you must pay for it.
4. 主、从句之间有插入语时。如： It says here, on this card, that it was used in plays. 卡片上写着，它是古代演戏用的。
5. 宾语从句的谓语动词是否定形式时，只能用 if，不能用whether。如： Tom wants to know if he won’t come here tomorrow. 汤姆想知道他明天是否不来这儿。 6. if意为“假如，如果”时，可以引导条件状 语从句，而whether没有这个用法。如： If Simon comes here tomorrow, I’ll call you. 假如西蒙明天来这儿，我将打电话告诉你。
3. They wondered if the teacher ______ us English the A next term. A. would teach B. had taught C. will teach D. taught
B any noise from outside. 4. The boy asked ______
Object clauses with if and whether
由if / whether引导的宾语从句

The journey to Mars could take only a very short time in space shuttles that travel at half the speed of light. Some scientists do not believe that the journey to Mars will be very comfortable.
2.在句子前加上从属连词 whether, if 变化方法： 主句 + if / whether + 一般疑问句。 该一般疑问句要变为陈述句形式。
if/whether 引导宾语从句 ，表示“是否”之义， 在句中不充当句子成份， if/whether可互换。
把下列各句变为宾语从句 1. Is Jim at home? (I wonder…) I wonder whether / if Jim is at home. 2. Is June a good time to visit Hong Kong? ( He wonders…) He wonders whether/ if June is a good time to visit Hong Kong.

4. 从句作介词宾语时，只能用whether。如：

其次要注意时态变化：
1. 若主句是一般现在时，从句用任何所需时 态。如：
He wants to know if / whether they had a good journey home. 他想知道他们回家旅途是否愉快。
2. 若主句是一般过去时，从句则用跟过去相 关的时态。 Did the train leave? She didn’t know. →She didn’t know if / whether the train had left. 3.若从句表达的是客观事实或一般规律，则 仍用一般现在时
Ⅲ. if和whether的区别
二者在下列几种情况下不能换用：
1. 宾语从句置于句首表示强调时，应用 whether，不用if。如： Whether this is true or not, I can’t say.
这是否对，我不能说。
2. 宾语从句与or not直接连用时，应用 whether，不能用if。如： I don’t know whether or not he will come tomorrow. 我不知道他明天是否来。
注：连词that不能省略的几种情况
1. 从句的主语是that。如：
He says that that is a real king’s hat.
他说那是一个真的王冠。
2. 若出现两个或两上以上的由that引导的宾语从句，
且由并列连词连接时，只有第一个连词that可以省
略。如：
