The child talked to us as if he were a grown-up. 那个小孩跟我们讲话就像个大人一样。 2． as if 从句的语气及时态 ①as if从句用述语气。当说话者认为句子所述的是真实的或极有可能发生或存在的事实时， It sounds as if it is raining. 听起来像在下雨。 He talks as if he is drunk. 从他说话的样子来看他是醉了。 ②as if从句用虚拟语气。当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时， 表示与现在事实相反，谓语动词用一般过去式。如： You look as if you didn’t care. 你看上去好像并不在乎。When a pencil is partly in a glass of water, it looks as if it were broken． 表示与过去或与谈话时间为止发生的事实相反，谓语动词用

as 用法详解
as 用法详解 1.用作连词，表示让步 (意为：虽然，尽管)，要用于倒装句，且倒装后位于句首的名词通常不用冠词 (等于though, 但语气稍弱)。如： Child as[though]he was, he did quite well. 他虽是个孩子，但已干得很不错。 2.用作关系代词，主要用法有二。如： (1)用在such, same, as等之后，引导限制性定语从句。如： This is thesame watch as I lost. 这块表跟我丢失的那块一样。 Such men as (=Those men who) heard of him praised him. 听说过他的人都赞扬他。 (2)单独用作关系代词，引导非限制性定语从句，可放在主句之前 (常译为：正如)或之后 (常译为：这一点)，且主从句之间一般要用逗号隔开。如： He was absent, as is often the case. 他缺席了，这是常有的事。 As was expected, he succeeded at last. 正如我们所料，他终于成功了。 3.用来表示目的，下面两种句子结构都可以。如： 仔细写以便把每句话都写清楚。 正：Write carefully so as to make every sentence clear. 正：Write so carefully as to make every sentence clear. 4.在正式文体 (尤其是文学体裁)中，as后可用倒装语序表示“…也一样”这类意思 (现代英语通常so表示这一用法)。如： He travelled agreat deal, as did most of his friends. 他去过许多地方旅游，他的多数朋友也是一样。 He plays the piano, as does his mother. 他会弹钢琴，他母亲也会。 注：用作连词，表示原因 (参见because)，表示时间 (参见when)。 5.用于 as if as though, 意为“仿佛”、“似乎”。两者一般可通用 (但注意不能说 as although)。用法上注意几点：
as-用法归纳和练习--(学案)
as 用法归纳和练习题 一、as作副词，表示程度，意为“同样地”。在“as．．．as．．．”，“not as/so．．．as．．．结构中的第一个as是副词，作“和／与．．．(不)一样”解。 Jack is as tall as his father． He doesn't speak English as／so fluently as you． 二、as作介词。 1．作“如，像”解。They got united as one man． 2．作“充当，作为”解。eg：As a writer，he was famous． 三、as作连词，常用来连接主句和状语从句。 1．引导时间状语从句，作“当．．．的时候”解，有“随着．．．”之意，与while意义相近，强调两个动作同时发生；或某事一发生，另一事立即发生。eg： He shouted aloud as her ran along．他一边往前跑，一边高声地呼喊。 I was startled as he opened the door．他一开门，我吓了一跳。 as作连词，相当于when。eg； As a little boy (When he was a little boy)he began to learn to play piano． 2．引导原因状语从句，作“因为，由于”解，与because的用法相近。eg； I must stop writing now，as I have rather a lot of work to do． 3．引导方式状语从句或比较状语从句，作“正如，(如)像”解。例eg： As in your country，we grow wheat in the north and rice in the south．正如(像)你们国家一样，我们在北方种小麦，在南方种大米。(方式状语从句) When at Rome，do as Romans do．入乡随俗。(方式状语从句) Leave it as it is. 保持原状，不要动它。 4．引导让步状语从句，作“虽然，尽管”解。这时从句常用倒装语序，即把从句中的表语、状语或动词原形放在as之前。eg； Strange as it may seem，it is true． 尽管这事看上去很奇怪，但却是真的。 Try as he might，Tom could not get out of the difficulties． 不管怎样努力，汤姆还是摆脱不了困境。 Child as he is, he know s a lot. Much as I like you, I will not marry you. 我虽然很喜欢你，可是不愿与你结婚。 四、as作关系代词。 1．引导限制性定语从句，用在“such．．．as”,“the same．．．as”，“as．．．as” “so… as”等结构中，常译作“像．．．一样的人(或物)”，“凡是．．．的人(或物)”。例eg： He wished to be such a man as Lei Feng was．他曾希望做一个像雷锋那样的人。 My hometown is no longer the same as it was．我的家乡再也不像过去一样了。2．引导非限制性定语从句，用来指代它前面的整个句子(即先行句)。这个分句可以位于句首、句中或句末。 As is well known，oceans cover more than 70％of the earth．

II) When the clock struck twelve, all the lights in the street went out. B. while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。 e.g. Work while you work. Play while you play.
