我们要表达甲是乙的几倍时,通常用下面三个句型来表示:1.“A+倍数+形容词或副词的比较级+than+B”,表示“A比B大(长、高、宽等)多少倍”.如:This rope is twice longer than that one.这根绳子是那根绳子的两倍长(比那根绳子长一倍).This hall is five times bigger than our classroom.这个大厅比我们的教室大四倍(是我们教室的五倍).The car runs twice faster than that truck.这辆小车的速度比那辆卡车快一倍(是那辆卡车的两倍).2.“A+倍数+as+形容词或副词的原级+as+B”,表示“A正好是B的多少倍”.如:Asia is four times as large as Europe.亚洲的面积是欧洲的四倍.This big stone is three times as heavy as that one.这块大石头的重量是那块的三倍.The plane flew ten times as high as the kite.那架飞机的飞行高度是那只风筝的十倍.3.“A+倍数+the size/height/length/width,etc+of+B”,表示“A正好是B的多少倍”.如:This street is four times the length of that one.这条街是那条街的四倍长.This hill is four times the height of that small one.这座山的高度是那座小山的四倍.

动词一般就是用来表示动作或状态的词汇。在英语中,动词按作用和功能主要分为两大类,一类是谓语动词,另一类是非谓语动词。英语动词还可以分成英语动词、连系动词、助动词、情态动词等几类。
1. 实意动词:大家可以这样去想,实意动词就是你看到、听到、说到到这个词,你会联想到一个“动作”,比如:look,会想到目光的聚焦或移动;eat---咀嚼和吞咽;run---撒开腿跑动;think---一副沉思的模样等等。
2. 连系动词:起到连系主语和表语的作用,有的老师也称之为“系动词”,像一纽带,把主语和表语“系”在一起。如:He is tall. 中的 is;You look tired. 句中的 look;It seems right. 中的 seems;sounds great 中的 sounds 等。
3. 【重点】助动词:理解“助动词”的关键在一个“助”字,助就是帮忙的意思,帮谁?帮实义动词。为啥帮?因为英语的“形合”属性,说通俗点,就是英语是动词在形式上很讲究,助动词的作用就是帮助句中的实义动词---又叫主动词---表现出“时和数”的概念。例如:
Do you like dogs? 中的 do,表明问的时间是--“平时”,主语的数--不是单三。
Did you like dogs? 中的 did,表明问的时间是--“过去”,实义的动词的过去时不讲究数,就没有反映数的单或复。
助动词并非只有 do 极其变化,will、can、is 都可以作助动词用,因为“助动词”是句子中实意动词的得力助手,所以助动词的形式变化是英语学习者必须掌握的重点!
4. 情态动词:上面说到 can ,情态动词也算助动词,只是其功能比较特殊,它们的作用是帮助主动词完成“情态含义”的表达。所谓“情态含义”不是一种动作,而是诸如“能、也许、将要、必须”等,情态动词的特点是--后面的动词不能变。
1、及物动词(Transitive Verb),缩写为:vt. 后面可以直接加人或事物。但是有些词既是及物又同时是不及物,意思也有微妙的变化。
例如最常见的:Like,
可以说是: I like you. 我喜欢你
也可以是: I do not like to swear. 我不喜欢话/ 我不想/我不愿意说脏话。
2、不及物动词(Intransitive Verb),缩写为: vi.,后面要加特定的介词才能加人或事物。若要跟宾语,必须先在其后添加上某个介词,如to,of ,at后方可跟上宾语。具体每个动词后究竟加什么介词就得联系动词短语了
延伸到“系动词”:
1)状态系动词:用来表示主语状态,只有be一词,例如:He is a teacher.
2)持续系动词:用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand, 例如:He always kept silent at meeting.他开会时总保持沉默。
3)表像系动词:用来表示“看起来像”这一概念,主要有seem, appear, look, 例如:He looks tired.他看起来很累。
4)感官系动词:感官系动词主要有feel, smell, sound, taste, 例如:This kind of cloth feels very soft. This flower smells very sweet.
5)变化系动词:这些系动词表示主语变成什么样,变化系动词有become, grow, turn, fall, get, go, come, run. 例如:He became mad after that.自那之后,他疯了。
6)终止系动词:表示主语已终止动作,主要有prove, turn out, 表达“证实”,“变成”之意,例如:The search proved difficult.搜查证实很难。
