Let me go instead. 他累了,让我替他去吧。 She never studies. Instead, she plays tennis all day. 她从不学习,而是整天打网球。(2)instead和instead of的辨析: instead是副词,后面不接其他的词,一般情况下可不译出,通常放在句首或句末,在句首时常用逗号隔开,表示前面的事没做,而做了后面的事。例如:He didnt go to school. Instead, he went to the cinema. 他没有去学校,相反他去了电影院。Instead of lending a hand, he laughed at us.他不仅没有帮我们一把,反而嘲笑我们。3. cut offcut off是固定搭配,意为“切除;切掉”。例如: The slide cut off the valley from the rest of the world. 山崩切断了这个山谷与外界的联系。 【拓展】“动词 + off”构成的短语有: take off 起飞,脱下 put off 推迟 turn off 关闭 get off 下车 fall off从掉下来 break off终止 pay off 付清 4. make a difference make a difference意为“起作用,有影响”。例如: The fact that I can now organize my own time makes a big difference. 现在我能自己安排时间了,这对我有很大的作用。 Whatever you can do can make a difference. 无论你能做什么,都会带来不同。5. the number of the number of意为“的数量”,后接可数名词复数,谓语动词用单数形式。例如: The number of people speaking Chinese is larger than that of those speaking English. 说汉语的人数要大于说英语的人数。【拓展】 a number of 意为“许多”,后面接可数名词的复数形式,谓语动词用复数形式。number前面可以用large,great,small等修饰,构成a large number of; a small number of等。例如: I have a number of letters to write. 我有许多信件要写。 A large number of students in our school are from the countryside. 我们学校许多学生来自农村。 A small number of students in our class went swimming yesterday. 昨天我们班一小部分学生去游泳了。6. 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 doesnt feel lonely.= He lives alone, but he doesnt 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:Its hard work; I enjoy it, though. 工作很辛苦,可是我很喜欢。We all tried our best.
