求have和get的用法全一点
have表示”使“时（即用做使役动词）的用法有三种：
1.have sb/sth do sth:表示使某人做某事.
例：The teacher has students do homework every day.
2.have sb/sth dong sth:表示使某人一直做某事
例：He has the horse running all day.
3.have sb/sth done:表示使某人被...
例：He has his hair cut by his father.
另外,表示动词时,“有”的意思.
I have a book.我有一本书.
Do you have a book?
I don’t have a book.（也可以说I haven’t a book.不常用）
表示助动词时.“使……” 的意思
have sb do 让某人做
have sb doing 让某人一直做
have sb/sth done 某人/某物被……
have to,“不得不,必须”,表示不是主观意愿
It’s dark outside,I have to go home.天黑了,我不得不回家.
Do you have to…….
I don’t have to…….
用于完成时
have+动词的过去分词
在由have作谓语的句子变疑问句或否定句时,在美式英语中,无论何种情况,都要借助于助动词do或does.例如：
Do you have a dictionary?
He doesn't have any coffee.
在英式英语中,现在时的否定句、疑问句通常不用助动词do而用have not,Have you...的形式,但最近受到美式用法的影响和一般动词一样,已渐有使用do的倾向.
have还可以和很多单词,特别是那些既是动词又是名词的词连用,构成很多短语,其词意则是由与其连用的词语来决定,它的活跃之处也就在于此.例如：
have a talk 谈话 have a tea 喝茶
have a rest 休息一会儿 have a class 上课
have a hike 远足 have a picnic 野炊
have a concert 举办音乐会 have a visit 参观；访问
have a look 瞧一瞧
have a sleep 睡一会儿觉
get的用法：
1.get sth done "使某事被做;遭受了..."
例如:I want to get my hair cut.我想剪发（头发被剪）
I got my feet hurt in the soccer game.双脚被别人伤到
2.get sth/sb to do sth "使得...去做某事"
在这里,sth/sb与do sth所表示的动作是主动/主谓的关系
如:Nobody can get him to work hard.他虽然是get的宾语,却是"努力工作"的主语
get sb to do 相当于 have sb do让某人做某事
get sb doing 相当于 have sb doing让某人一直做某事
get sb /sth done 相当于 have sb/sth done
使某人或某物被做
