What''''s the different between if and wheather,
lonely and alone,made of and made from?
一:
1.if作“是否”讲的时候,与whether同义,都可引导宾语从句,可以互换
2.口语中常用IF,但是从句中有OR NOT 的时候,则只能是用WHEATHER,例如:I don‘t know whether it’s raining or not.
3.另外,WHETHER可以引导主语从句,表与从句,同位语从句,IF 则不能,IF(意为“如果“)可以引导条件状语从句,WETHER则不能,WETHER可以和不定式连用,IF 则不能。He doesn‘t know whether to accept the invitation.
4.WHETHER引导的宾语从句可以放在介词后面,IF引导的宾语从句则不能。例如:
It depends on whether he is coming。
二:
alone 是形容词(通常是表语形容词),又是副词。而 lonely 只是形容词。
。alone 是单独,独自的意思。而 lonely 是孤独,寂寞,冷清的意思,有感情色彩
三:
从外观上可直接看出构成某物的原材料如cotton,silk,metal,iron,steel,gold,wood等物质名词,用be made of,如从外观上看不出构成某物的原材料原来的样子,用be made
