A.to keep B.keeping C.keep D.kept (句意为:“我们可以生火来保持房间暖和,以便你们可以聊一会儿”。此处为动词不定式短语作目的状语。答案:A) 【拓展记忆】课本原句“…made a fire to keep us warm and cook food on.”=“…made a fire to keep us warm and to cook food on a fire.”,意思是:生火的目的是取暖和做饭,而做饭是在火上做。课本中to keep…和(to )cook…都是make a fire的目的,句中省略了to 和a fire,以避免重复。试分析下题:Why don’t you write?Sorry,I have no pen . A.to write B.to write on C.to write with (答案选C。 这是一个动词回头现象。意思是“我没有钢笔写字”,pen既做have的宾语又做write的宾语。用笔写是“write with the pen”,不能说成“write the pen”。在动词回头中省略掉第二个重复的宾语(the pen),所以选C。)【思考】为什么有的动词后加介词,有的不加介词呢?主要看to后的动词是否及物,不及物动词加名词前要先加一个介词(get to Beijing/arrive in Beijing/run to school/come to Rizhao……)。例如:I have a small room to live in.我有个小房间住。(注意有in) He is a pleasant fellow to work with . 他是个很好共事的人。(注意有in) I have a lot of things to do.(这个句子中不定式的动词do是及物的,不用加介词。) 7.On the first night,we just sat under the moon and told each other stories.在第一天晚上,我们就坐在月光下,互相讲故事。 【重点注释】①on the first night意为“在第一天晚上;在头一天夜里”,表示“在具体某一天的上午、下午或晚上” 等的特定时间,常用介词on,而只说“在夜里”是“at night”,在上午“in the morning”,在下午“in the afternoon”,在晚上“in the evening”。例如:On the evening of October 10th,she got a special gift.在10月10日的晚上,她得到了一件特别的礼物。 ②each other意为“互相;相互;彼此”,相当于one another。英语中each other为代词,在及物动词之后可直接用作宾语;而在不及物动词之后,则要借助介词。例如:They helped each other.他们互相帮助。We liked each other a lot.我们彼此都很喜欢对方。We help each other and learn from each other.我们互相帮助,互相学习。We talked to each other.我们互相交谈。The students borrowed each other’s notes.学生们互借笔记。【注意】each other可加-’s构成所有格each other’s。 8.But I was so tired that I went to sleep early.但是我太累了,所以早早就睡着了。 【重点注释】so…that…“如此……以至于……;太……以致……”,引导结果状语从句,其中so是副词,常常用来修饰形容词或副词;so后跟形容词或副词,that后跟从句(句子)。常用句型有两种:(1)主语+谓语+so+形容词或副词+that从句。例如:He is so young that he can’t look after himself.他是如此年轻,以至于他不能照看自己。He was so angry that he couldn’t say a word.他非常生气,以至于一句话也说不出来。The boy ran so fast that I couldn’t catch up with him.男孩跑得如此快,以至于我追不上他。I was so tired that I went to bed as soon as I ate the supper.我太累了,以致我一吃完晚饭就去睡觉了。She is so beautiful that many people like her.她太漂亮了以致很多人喜欢她。The coffee is so hot that I can't drink now.咖啡太热了以致于我现在不能喝。The man is so strong that he can lift the heavy box.男人太强壮了以致他可以抬起这个重箱子。He was so clever that he can understand what I siad.他太聪明了以致他可以理解我讲了什么。The box is so light that he can carry it.箱子太轻了以致他能背起它。(2)主语+谓语+so+形容词+a/an+单数名词+that从句。例如:She made so good a meal that we all ate far too much.她做的饭菜那么好吃,结果我们都吃得太多了。It was so good an exhibition that I went to see it several times.展览是那么好,结果我去看了好几次。It was so fine a day yesterday that we all went out for a picnic.昨天天气很好,我们都出去野餐了。 【试题链接】The soccer match was exciting that everyone was cheering and jumping.
