b、as起连接作用,表达说话人的观点、看法,并指出主句内容的根据或出处,意为“正如,正像”。

距离高考还有一段时间,不少有经验的老师都会提醒考生,愈是临近高考,能否咬紧牙关、学会自我调节,态度是否主动积极,安排是否科学合理,能不能保持良好的心态、以饱满的情绪迎接挑战,其效果往往大不一样。
以下是本人从事10多年教学经验总结出的以下学习资料,希望可以帮助大家提高答题的正确率,希望对你有所帮助,有志者事竟成!养成良好的答题习惯,是决定高考英语成败的决定性因素之一。
做题前,要认真阅读题目要求、题干和选项,并对答案内容作出合理预测;答题时,切忌跟着感觉走,最好按照题目序号来做,不会的或存在疑问的,要做好标记,要善于发现,找到题目的题眼所在,规范答题,书写工整;答题完毕时,要认真检查,查漏补缺,纠正错误。
总之,在最后的复习阶段,学生们不要加大练习量。
在这个时候,学生要尽快找到适合自己的答题方式,最重要的是以平常心去面对考试。
英语最后的复习要树立信心,考试的时候遇到难题要想“别人也难”,遇到容易的则要想“细心审题”。
越到最后,考生越要回归基础,单词最好再梳理一遍,这样有利于提高阅读理解的效率。

高考英语基本句型英语中常见的句型有以下五种:1、主语 + 谓语2、主语 + 谓语 + 宾语3、主语 + 谓语 + 间接宾语 + 直接宾语4、主语 + 谓语 + 宾语 + 宾语补足语5、主语 + 谓语(系动词)+ 表语一、主谓结构I write、(我写字)You smile、(你微笑)He leaves、(他离开了)She dances、(她跳舞)The river floods、(河水泛滥)The accident happened、(那场事故发生了)某人(或事物)做某事,其中某人(或事物)是动作或行为的发起者,我们称其为主语,后面的动作或行为我们称之为谓语。
二、主谓宾结构I write a letter.You leave your home.He goes to school.She beats me.The flood destroys many houses.The accident causes 2 deaths.上述句子的共同点在于除了表示某人(或事物)做某事之外,还牵涉了另一个人(或事物),这个人(或事物)作为动作或行为的承受者,我们称其为宾语。
三、主谓+双宾结构I write you a letter.His father left him a lot of money.He bought me a new phone.She told me the truth.The government gave him a new mission.在主谓宾结构之外,上述句子又增加了一个人(或事物)作为动作的承受者,也就是又一个宾语。
也可以改写为:I wrote a letter to you.His father left a lot of money to him.He bought a new phone for me.She told the truth to me.The government gave a new mission to him.可以看到,这样调整之后句子的前半部分仍然是完整的主谓宾结构。
2016高考英语语法必考点与常考点归纳一、冠词冠词分为不定冠词(a, an),定冠词(the),和零冠词。
二、名词和主谓一致特别注意:名词类别的相互转换抽象名词与个体名词的转换规则名词的复数形式:名词的复数形式,一般在单数形式后面加-s或-es(参看有关语法书)。
英语里有些名词的复数形式是不规则的,请看下表三、代词四、形容词和副词I. 形容词注意:多个形容词修饰同一个名词的顺序熟记口诀就可以顺利解题:限定描绘大长高,形状年龄和新老,颜色国籍跟材料,作用类别往后靠。
规则:限定语(The、A)+ 描绘性形容词+ size(小)+ shape(形状)+ age(年龄、时间)+ color(颜色)+ origin(国籍、来源)+ material(材料)+ purpose(目的)+ 名词。
▲This ________ girl is Linda’s cousin. (05北京卷)A. pretty little SpanishB. Spanish little prettyC. Spanish pretty littleD. little pretty Spanish3.形容词(短语)作伴随状语As he looked at the goat, it rolled over, dead. 当他看着山羊的时候,山羊翻了个身,死了。
Afraid of difficulties, they prefer to take the easy road.由于害怕困难,他们宁愿走好走的路。
形容词和副词的比较等级分为原级,比较级和最高级。
比较级和最高级的构成一般是在形容any, a great deal ;2.表示“最高程度“的形容词没有最高级和比较级。
如:favourite, excellent, extreme, perfect ,superior,junior 等。
五、动词和短语动词六、动词的时态和语态注:现在分词、不定式、过去分词都可以作独立成分generally speaking一般说来;frankly speaking坦白地说;judging from/by...根据……来判断;considering.../taking...into consideration考虑到……;to tell you the truth说实话;seeing...考虑到……;supposing假设,如果;providing如果;given考虑到,鉴于;provided that如果常见的非谓语动词形式1.To do 表示将要发生的动作2.To be done 表示将要发上的被动动作3.To have done 表示已经完成的动作4.To have been done 表示已经完成的被动动作5.To be doing 表示正在发生的动作6.Doing 表主动进行7.Being done 表示正在发生的被动动作8.Having done 表示done这个分词的动作发生在主句谓语动词之前9.Having been done 表示been done 这个被动动作发生在主句谓语动词之前10.V-ed过去分词表被动完成在解非谓语习题时同学们遇到最大的困难有两个:一是如何判别是谓语动词还是非谓语动词;二是如何选用哪一种非谓语动词及其恰当的形式。

句意:你的善良我怎么感谢都不为过,因为没有你的帮助,我就不可能在考试中成功。
“can’t… too…”表示“再/做……也不为过/不过分”,是一个常用的句式,符合本题句意。
故选B。
【点睛】cannot/ can’t/can never与too,too much,enough,over搭配是英语中一个十分有用的表达,意为“不可能太……,无论样…….也不算过分,越.….越.…”。
有时也可用impossible等与too连用来表示类似意思。
例如本题中使用的就是其中最常见的结构can’t...too...(再……也不为过,越……越好)。
2.A解析:A【解析】【详解】考查固定句式。
句意:海伦正要出门,这时突然电话铃响了。
be about to do when…是固定句式,表示“正要……这时(突然)某事发生”,故A项正确。
3.B解析:B【解析】【详解】考查强调句。
句意:只有当人们以非常有限的饮食为生时,才有必要做出特别的努力来供应缺少的维生素。
分析句子结构可知应为it is +强调时间状语+____+其他内容,应为强调句结构,因此所填空应为that。
故选B项。
【点睛】如何判断强调句:从本质来说,将句子中的It was/is that去掉后,剩下的句子重新整理可成立的话,是强调句。
比如本题 It is only when people live on à very limited diet_____ it is necessary to make a special effort to supply the missing vitamins.,根据判断原则,将it is 去掉之后,句子为only when people live on à very limited diet_____ it is necessary to make a special effort to supply the missing vitamins,其中,only when people live on à very limited diet 为句子的时间状语从句,主句为it 做形式主语,真正主语为之后的动词不定式结构to make a special effort to supply the missing vitamins,is 为系动词,necessary为表语。
