3、 hether和if引导从句的用法。3 get的用法【重难点分析】1 uld u ind?和D u ind? 用于询问或请求别人做某事，或请求他人的许可。(1)ind后面可以用-ing形式，复合结构 nes ding或if引导的从句。 例如： uld u ind ding the dishes? D u ind ding the dishes？ Please d the dishes 请把餐具洗了好吗? (表示请求别人做事) uld u ind turning dn the radi? D u ind turning dn the radi? 请把收音机关小点好吗？(2)uld u ind d

4、ing? = D u ind if I d? 这个句型用于询问他人意见或请求他人的许可。 例如： uld u ind sing here？ D u ind if I se here? 你介意我在这里吸烟吗？ uld u ind asing u a questin? D u ind if I as u a questin? 我问你一个问题好吗？ uld u ind pening the ind? D u ind pening the ind? an I pen the ind? 我可以开窗吗? 注意： 在美国口语中还可以将这个句型用uld u ind e ding sth？表达，但是在书面表达中

5、要用。 uld u ind e using ur ar? 我用一下你的车好吗？(3)询问有关人们感觉的一般性问题，可以用D u ind?通常不用uld u ind? 如： D u ind peple sing in ur huse? 你介意别人在你家里吸烟吗? 这里不能说uld u ind peple sing in ur huse?(4)这个句型的否定形式是在ind后加nt，即uld u ind nt?或D u ind nt? 如： uld u ind nt plaing basetball here? 你不要在这打篮球好吗？ uld u ind nt earing thse ld eans

6、?()回答Duld u ind? 提出的问题时，表示允许要说N或Nt at all等； 如果介意要做肯定回答es 或es，I srr，but I d等， 如： -D u ind if I as u a questin? 我可以问你的一个问题吗? -N，please d可以，请问吧。2 通常既可用hether 也可用if 表示“是否”引导从句，常置于see，as，learn，tell，nder，dubt，find ut等动词之后。 如： I nt sure hether /if Ill have tie 我不敢肯定我是否会有时间。 He ased e hether/if I uld help h

7、i I ant t n hether/if he lives there只能使用hether的场合(1)只有hether能用在介词后面 如： Suess depends n hether e ae enugh effrt(2)在英语中与r (nt) 连用的词通常是hether 如： hether e help hi r nt，he ill fail 不论我们帮助他与否， 他都将失败。(3)带t的动词不定式前用hether，而不用if 如： Please tell us hether t g r sta here请告诉我们是走还是留。 The didnt n hether t agree r e

8、ep silent 他们不知道是应该同意还是保持沉默。(4)hether可置于句首引导主语从句，而if不能 如： hether the eeting ill be in Beiing is nt nn et 会议是否在北京举行还不得而知。 Its nt sure hether he is free 他是否有时间不确定。3 get n / get ff ( a / the bus，train，bat，plane) 上/下（公共汽车、火车、船、飞机） 如： She gt n / ff the bus quil get n还可以表示为：相处融洽、继续。 如： Get n ith ur r! 继续工作

9、吧！ I get n ell ith all lassates 我和所有的同学相处都很融洽。 get的其它的用法：(1)表示“到达，抵达”，如果后接表示到达某地的名词，get后面要接介词t，如果get后接的是地点副词就可以直接在get后使用。 如： She gt there at six 她六点钟到达那里。（there为地点副词） hen e gt t the statin， the bus as aiting 当我们到达车站时，汽车还在等着。（the statin是名词）(2)get sth dne使；受；让人做好；经历；让；做（该做的事） 如： Ill ust get these dish

10、es ashed and then Ill e 我得把盘子洗了，然后就。 I ust get the televisin fixed 我必须请人修理一下这台电视机。(3)get与宾语+形容词连用，其意思是“使某物/某人成为” 如： I gt feet et 我把脚弄湿了。 Its tie t get the ids read fr shl 该给孩子们收拾好去上学了。 (4)成为 如： hands are getting ld 我的手冷。 The fds getting ld 菜凉了。 This sirt is getting dirt；it needs ashing 这短裙脏了，该洗一洗了。
