用语aswell 与as well as用法归纳
用语a s w e l l与a s w e l l a s用法归纳?as well与as well as只有一词之差，但意义和用法却相差甚远。
一、as well 用法：?
?
1、as well常用作状语，作“又；也”解，相当于too或also，常位于句末，无须用逗号与句子分开。如：?
?
I am going to London and my sister is going as well（＝going，too）.我要到伦敦去，我妹妹也要去。?
?
?? I not only play the guitar，I sing as well（＝I also sing ）. 我不但弹吉他，而且还演唱。?
?
2、as well 在口语中也可用于句中，作“也好，也行”或“倒不如”解，用来缓和语气。如：?
?
?? You may as well go. 你去也好。?
?
?? The weather was so bad that we might（just）as well have stayed at home.
?? 天气太坏了，早知道如此，倒不如呆在家里为好。?
?
3、as well 可以直接用于just后，用作应答语（可视为It's just as well、的省略），作“幸亏，幸而；无妨；没关系”解。如：?
?
?? —We were too late to see the film.我们去得太晚了，没有看上电影。?
?
?? —Just as well、I hear it isn't very good. 不必遗憾，我听说电影也不怎么样。?
二. as well as
一、分清本义与引申义
1.?用于本义
as well as?用于本义，可视为as…as结构与well的自然搭配，其意为“与……一样好”，在否定句中可用not so well as代替?not as well as。如：
He speaks English as well as her.?他说英语说得跟她一样好。
She plays every bit as well as the men.?她打得一点不比男人们差。
He sings as well as, if not better than, Mary.?要是他唱歌不比玛丽唱得更好，但至少也是一样好。
2.?用于引申义
用于引申义，表示“不但……而且”“既是……也是”“而且”“还”。如：
He grows flowers as well as vegetables.?他既种菜也种花。
She shares (in) my troubles as well as my joys.?她与我同甘共苦。
注：有时还可译为“除……之外，还”，与besides, in addition to的用法相似。如：
As well as learning to swim, he has been taking Spanish lessons this summer.?今年夏天，他除了学习游泳外，他还在上西班牙语课。
二、弄清强调重点
A as well as B这一结构强调的重点是A不是B，即?A as well as B=not only
B but also A，注意体会以
下例句的译文：
She is clever as well as beautiful.?她不但漂亮，而且聪明。
He speaks Spanish as well as English and French.?他不仅会说英语和法语，而且会说西班牙语。
三、把握主谓一致
当?as well as?连接两个成分作主语时,?其后的谓语通常要与前面一个主语保持一致。如：
Tom as well as his parents is going to?London.?汤姆和他的父母要去伦敦。
The captain, as well as the other players, was tired.?队长和其他队员都累了。
四、牢记后续动词的形式
as well as?后接动词到底是该用什么形式，这是一比较复杂的问题，归纳起来有以下几点值得注意：
1.?as well as?通常被视为介词，所以后接动词时，一般用动名词形式。如：
He sings as well as playing the piano.?他不但会弹钢琴，而且会唱歌。
As well as breaking his leg, he hurt his arm.?他不但摔断了腿，而且还伤了胳膊。
She is a talented musician as well as being a photographer.?她不但是摄影师还是个天才的音乐家。
注：as well as?后接动词用动名词的情况主要见于主句谓语为简单时态(即一般现在时和一般过去时)的时候。
2.?如果主句谓语为复合时态(即其中含有情态动词或助动词)，则as well as?后的动词通常要与情态动词或助动词后的动词形式保持一致。如：
Students should pursue their own interests, as well as do their school work.?学生不仅应该做要好家庭作业，而且还要有自己的兴趣。
I have to feed the animals as well as look after the children.?我不但要照顾孩子们，而且还要喂动物
3.?如果as well as?是连接两个不定式，则其后用不带to的不定式。如：
A museum should aim to entertain as well as educate.?博物馆不仅要有教育性还且还要有娱乐性。
We cannot expect her to do the homework as well as look after the children.?我们不能指望她既做作业又照看孩子。
4.?当as well as?用于句首时，其后习惯上要接动名词。如：
As well as eating a seven-course meal, they drank three bottles of wine.?除吃了一顿有七道菜的饭之外，他们还喝了三瓶酒。
As well as walking, he likes fishing and shooting.?他除散步之外还喜欢钓鱼和打猎。
As well as visiting?Niagara Falls, we spent a day in?Toronto.?我们参观了Niagara?瀑布，而且学在多伦多玩了一天。
注：as well as?有时也被视为准并列连词，后接的动词可以与主句谓语动词形式一致（但这种情形远不
如用后接动名词普遍）。如：
He publishes as well as prints his own books.?他不但印刷而且还出版自己的书。
as-if-用法归纳
as if 用法归纳 1． as if 从句的作用as if一般可由as though来代替。 引导表语从句，可在look, seem等系动词后。如： He looked as if / though he was ill. 他看起来好像生病了。It seems as if it is going to rain.看来好像要下雨了。 引导方式状语从句。如： I remember the whole thing as if / though it happened yesterday. 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
“had +过去分词”。如： He talked about the Great Wall as if he had been there before.说起长城来好像他以前去过那里。 The girl listened as if she had been turned to stone.女孩听着，一动也不动，像已经变成了石头。 表示与将来事实相反，谓语动词用“would / could / might + 动词原形”。如： He opened his mouth as if he would say something. 他开嘴好像要说什么。 It looks as if it might snow. 看来好像要下雪了。 3． as if从句中的省略。如果as if 引导的从句是“主语+系动词”结构，可省略主语和系动词等成份，这样as if 后就只剩下名词、不定式、形容词（短语）或动词-ing形式等。 He acts as if (he was) a fool. 他做事像个傻子。 He paused as if (he was going) to let the sad memory pass. The girl left the room hurriedly as if (she was) angry. 女孩匆忙离开房间，好像生气的样子。 From time to time, Jason turned round as if (he was) searching for someone. 词汇学习 1. A smelly gas came out of the cracks.

Finding work is difficult these days. Walking is a good form of exercise for both young and old.

enjoyable，interesting ，foolish ，difficult ，useless，senseless，worthwhile 等。但是 important ， essential，necessary等形容不能用于上述构。 用it 代替名作形式主的除了上述句型外，有一种句型： It is no use/ useless/ useful/ no good/ great fun/ a waste of time/ nice/ good+ v-ing 例如： It ’ s no use trying to argue with him. 3）“ There be”的构 种句型一般是否定形式，There 是引，作形式 主，名做真正主。意思是“不可能??”。 例如： There is no joking about such matters. 4）告示或略的警告用中，名在祈使句中作主 一般是否定的、省略的形式。 例如： No climbing.（No climbing is allowed.） 5）成复合构 名有自己的主，可在其前面加上所有格， 使之成复合构，可作句中主。 例如：

It的用法及典型句型归纳. 个人总结
It的用法及典型句型归纳 一、人称代词it的最基本用法是作代词，主要指刚提到的事物，想法，以避免重复;也可以指性别不明或性别被认为是不重要的人或动物；未指明但谈话双方都明白的事情或情况。 ①They watched the train until it disappeared in the distance. ②Is this your dog？No, it isn’t. ③I hate it when people talk with a full mouth.． 二、.非人称代词.it有时并不指具体的东西而泛指天气、时间、日期、距离、价值、度量、温度、环境等： It is a lovely day, isn’t it? // It was nearly midnight when she came back. It is April First today. // It is some 3000 kilometers from A to B. It is three dollars. // Today it is 30 degrees centigrade. 三、作形式主语，替代主语从句，动词不定式，或动名词短语 1.作形式主语替代主语从句 ⑴It is clear ( obvious，true，possible，certain....) that ＂┅清楚的（显然的，真的，可能的,肯定的．．．）＂ ⑵It is important ( necessary，right，strange，natural...) that + (should ) do (虚拟语气) ┅是重要的(必要的,对的,奇怪的,自然的┅) ⑶It is said (reported/ learned/believed/thought/known/told/hoped.....) that = sb / sth is said (reported/ believed /thought…) to do( to be doing/ to have done) sth ＂据说（据报道，据悉．．．）＂。 ⑷It is suggested ( advised/ ordered / demanded/ insisted/ commanded... ) that +(should ) do ＂据建议；有命令．． ⑸It is a pity ( a shame /an honour/a good thing/a fact,/a surprise/... ) that that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。 小练一下： It is very clear that he’s round and tall like a tree. = It is important that we (learn) English well. It is necessary that he (remember) these words. It is said that he has come to Beijing. = It is reported that another earth satellite has been put into orbit. = It is suggested that the meeting ( put off).

It is kind of you to give me a hand. = ⑵It is necessary ( for sb. ) to do sth. .不定式的逻辑主语是由for引起。常见的形容词有： Important/ necessary/ natural/ easy / safe / common / normal / hard / difficult / dangerous/ unusual/ rare / impossible / pleasant Eg.
