(课件网) 第二讲 非谓语动词 考点突破 · 精讲即练 非谓语动词概述 1.什么是非谓语动词 非谓语动词是动词的特殊形式,在句子中可以充当谓语以外的成分。 2.非谓语动词在句子中的作用 一个句子中已存在一个谓语动词,又没有连词的情况下,再出现一个动词则用非谓语动词。 She got off the bus,but she left her handbag on the seat.(有并列连词,所以用谓语动词) She got off the bus,leaving her handbag on the seat.(没有连词,所以用非谓语动词) 3.非谓语动词的种类:动词-ing形式、过去分词和不定式。 考点一 非谓语动词作状语 一、动词不定式作状语,表示目的、结果、原因等 1.作目的状语,有时也用in order to或so as to,但so as to不用于句首。 (2022·全国甲卷满分作文)We will continue our campaign to prevent and control ocean pollution to make our oceans clean. 我们将继续我们的运动,以预防和控制海洋污染,使我们的海洋变得干净。 2.作结果状语,常用结构enough to, too...to..., only to 等。 I'm too tired to stay up any longer. 我太累了,实在不能再熬夜了。 3.作原因状语,此时常与表示情感的形容词连用,如glad, happy, frightened, surprised 等。 I was frightened to find that in front of my door sat a dog. 我惊恐地发现我家门前坐着一只狗。 二、动词-ing 形式作状语 动词-ing 形式作状语,常表示原因、伴随、时间、结果等,与句子主语之间存在逻辑上的主谓关系。 Walking in the street,I came across an old friend.(时间状语) 走在大街上,我碰到一个老朋友。 Having waited in line for two hours,the old man became impatient.(原因状语) 已经排了两小时的队,这个老人变得不耐烦了。 His parents died, leaving him an orphan.(结果状语) 他的父母去世了,让他成了孤儿。 【点津】 动词不定式作结果状语时,常表示意想不到的结果;而动词-ing 形式作结果状语时,常表示自然而然的结果。 三、过去分词作状语 1.过去分词作状语,分词与句子主语之间存在逻辑上的动宾关系。 Seriously injured, she has to be sent to the hospital at once. 她受了重伤,必须马上送往医院。 2.某些动词的过去分词已经形容词化,且往往用于一些系表结构中,此时这些过去分词既不表示被动,也不表示完成,而表示一种状态,如lost (迷路的), seated (坐着的), hidden (隐瞒的), lost/absorbed in (沉溺于), dressed in (穿着……的), tired of (对……感到厌倦的)等。 Absorbed in the book, he didn't notice me enter the room. 他完全被这本书所吸引,没有注意到我进入房间。 【点津】 独立成分作状语,其形式不受上下文的影响。常用的有considering that...(鉴于……;考虑到……);generally speaking(总的来说); judging by/from...(从……来看;依据……来判断); supposing that...(假定……); providing that...(假定……); owing to...(由于……); talking/speaking of...(谈及……); given that...(考虑到……);provided that...(如果……); to tell the truth (实话实说);to be honest (老实说)等。 即时演练(一) 单句语法填空 1.He hurried to the station, only _____ (inform) that the train had left. 2._____ (remember) all the questions you have when you are not in the doctor's office, write them down and bring the list with you to your appointment. 3.He was a tall man in his fifties, _____ (dress) in a business suit. to be informed To remember dressed 4.She has never seen s ... ...
