3、ovely a boy that everyone loves him.时间状语从句中when,while,as的区别有哪些下面是着重为大家讲解:时间状语从句中when,while,as的区别1)when引导从句时,主从句的动作有先有后,也可以同时进行,从句的动作可以是持续性的,也可以是短暂的。如: WhenIgottotheairport,theplanehadalreadytakenoff.(主先从后)(短暂性) WhenIlivedthere,IusedtogototheseasideonSundays.(同时)(持续性) Whenthemovieended,thepeoplewentb
4、ack.(从先主后) 2)while侧重主从句动作的对比,且从句的动词必须是持续性的。如: Whilewewerechattingshewaslookingatthetimetableonthewall 3)as引导从句时侧重主从句动作同时或几乎同时进行,从句的动作可以是持续性的,也可以是短暂的。如: SometimesIwatchTVasIamhavingbreakfast 4)when和while还可以是并列连词,意思分别是“就在这时”,“然而”。如: Iwashavingarestonthesofawhenthetelephonerang Theyweresurprisedthatach

6、有细微的差别,因为for并不是严格意义上的连词,所以它们的用法有区别。下面,小编就来给大家细细讲解一下。地点状语从句是常用状语从句的重要分类,在日常生活中使用率较高,难度也不大,因此也容易被忽略,可即使是这类较为简单的语法知识,在学习的过程中也有许多不能忽视的要点。表示原因,可用because,for,since,as,now,that,seeing that等从属连词。For是介乎并列连词与从属连词之间的,现在我们把它放在从属连词中与because作比较说明。because与for都可引导原因状语分句,既可以表示“直接理由”,即对某一情况说明原因:We hurried because / f
7、or it was getting dark.也可表示“直接理由”,即对说话人为何持此看法说明理由:It must be very late, because / for the streets are quite deserted.在这里,because- / for- 分句并不是为“天已很晚”这一事实说明原因,而是为说话人为何作此推断提供理由,相当于:It must be very late, and I claim it because / for the streets are quite deserted.言下之意,我之所以作此判断,是因为街上已经没有人了。从以上意义来看,连词for
8、与because的用法基本相同,从而接近于从属连词,只是because比for语势较强罢了。在当代英语中,凡是for与because可以互换的场合,通常用because为多,因为for-分句常见于正式语体,在非正式语体(特别是口语中)for-分句往往带有书卷气。另一方面,because与for的用法也有不同之处。第一,作为原因状语,because-分句位置比较灵活,既可位于主句之前,也可位于其后。例如:The doctor looks tried and sleepy because hesatup all night with the patient.Because hesatup all
9、night with the patient, the doctor looks and sleepy. 医生彻夜守护病人,他看起来疲惫不堪。语法辨析:wherever引导的两类状语从句引导地点状语从句,表示“在的任何(所有)地方”,与where, anywhere, everywhere 用法相似。如:You can sit wherever you like. 你喜欢坐哪儿都可以。You cant camp wherever where, anywhere you like these days. 如今你可不能随便在哪儿宿营。引导让步状语从句引导让步状语从句,表示“不管在(到)哪里”,相当
10、于no matter where。如:Wherever he goes, Ill go. 不管他去哪里,我也去。Wherever you find high wages, you will generally find high prices. 哪里有高工资,哪里一般就有高物价。Being recognized wherever you go is the price you pay for being famous. 出名所付出的代价是不管你走到哪里,都会被人认出来。从句谓语有时可以用“may+动词原形”代替一般现在时。如:Ill find him, wherever he is may b
11、e. 无论他在哪里,我都要找到他。下面一句中的wherever possible 与 whenever possible 同义Wherever possible the jobs are given to local people. 只要有可能就把工作提供给当地人。条件状语从句中unless和if not 的区别1. 当所述条件会结束已经存在的想法,状态或趋向时,两者都可以。We shall go unless it rains tomorrow. =We shall go if it doesnt rain tomorrow. 如果明天不下雨,我们就去。( “下雨” 会结束 “去” 这一已经
12、存在的趋向) You will be late unless you take taxi. =Youll be late if you dont take taxi. 如果不打的你就要迟到。( “打的” 会结束 “迟到” 这一趋向)2. 当所述条件会导致一种新的想法或状况时,通常用if not。 Ill be late if you not let me go now. 你如果不让我现在走我会迟到的。(“不让现在走”就会导致“迟到”这种新情况)3. 表示虚拟条件,既与实际事实相反的状况时,只能用if not。 She would be angry if you had not invited her to party. 你要是没邀请她,她肯定生气。4. 和否定表达连用时,只能用unless。 I will go unless nobody invite me. 除非没人邀请我,否则我肯定会去。学科网(北京)股份有限公司
