词句精讲精练
词汇精讲
1. maybe
maybe是副词,意思是“也许,可能”,在句中作状语,相当于perhaps,常位于句首。 例如:
Maybe she’ll come this afternoon. 她可能今天下午来。
Maybe you put the letter in your pockets. 大概你把信放在衣袋里了。
【拓展】
(1)maybe和may be的辨析:
maybe是副词,而在may be中,may是情态动词,be是动词原形,两者构成完整的谓语形式,与主语形成系表结构,意为“也许是、可能是”。 例如:
I can’t find my watch. It may be in your pocket.
我找不到我的手表了,它可能在你的口袋里。
He may be a soldier. 他可能是军人。
(2)maybe和may be可相互转换。 例如:
He may be in the office. = Maybe he is in the office. 他或许在办公室。
You may be right. = Maybe you are right. 你或许是对的。
2. although
although的意思相当于though,意为“尽管,虽然”,用来引导让步状语从句。它所引导的从句不能与并列连词but; and; so等连用,但可以和yet; still等词连用。例如:
Although he lives alone, he doesn’t feel lonely.= He lives alone, but he doesn’t feel lonely.
虽然他一个人住,但他并不感到孤独。
There is air all around us, although we cannot see it.
虽然我们看不见空气,但空气却存在于我们的周围。
【拓展】although与though的辨析:
(1)用作连词,表示“虽然”,二者可以互换使用,但although比though更为正式。
例如:
Though/Although it was raining, we still went there.
虽然下着雨,但我们还是去了那里。
(2)although一般不用作副词,而though可用作副词,且一般放在句末(不放在句首),意为“可是,不过”。例如:
It’s hard work; I enjoy it, though. 工作很辛苦,可是我很喜欢。
We all tried our best. We lost the game, though.
我们都尽了最大努力,但我们还是输了。
(3)在as though(好像,仿佛),even though(即使,纵然)等固定短语中不能用although。例如:
He talks as though he knows everything. 他夸夸其谈,好像无所不知。
3. die
die是动词,意为“死亡”,是短暂性动作,常用于过去时中,过去式为died。例如:
Plants and people will die without water. 没有水,植物和人都会死。
His father died two years ago. 他的父亲两年前去世的。
