人称代词表格,用法及练习
人称代词表格
i.人称代词:
人称代词又分为主格和宾格形式.主格通常做主语。
宾格通常做动词或介词的宾语.
eg:
a.manurse.
b.c.d.e.f.’“mimi.”
ii.物主代词又分为形容词性的物主代词和名词性的物主代词.
形容词性的物主代词:
相当于形容词,后面要跟名词,指定名词的所属对象.名词性的物主代词:
相当于一个名词,必须单独使用,后面不能再跟名词.eg:
c.whosebookisthatit’sd.isonthesecondfloor.isonthethird
floor.(=ourclassroom)g.thosearen’t
*人称代词划线,常用who(宾格可用whom)提问.物主代词划线常用whose提问。
(特别提示):
并列人称代词的排列顺序
1)单数人称代词并列作主语时,其顺序为:
第二人称-------第三人称--------第一人称
you-------he/she/it--------i
eg:
you,heandishouldreturnontime.
2)复数人称代词作主语时,其顺序为:
第一人称-------第二人称-------第三人称
we------you---------they
iii.指示代词:
this这个,that那个these这些those那些

***为帮助同学们理解和掌握英语人称代词,请记住下面的口诀:
人称代词分主/宾,只有八对要区分。
你(们)、它主/宾同一形,其余主/宾须分清。
谓语之前主格填,动/介之后宾格跟,
口语运用最灵活,表语也可用宾格。
人称代词并列现,注意顺序礼貌见,
二一、三一、二三一,第一人称最谦虚,
若把错误责任担,第一人称须当先。
篇三:
答案
(5)设哈希表的地址范围为0~17,哈希函数为:
h(key)=key%16。
用线性探测法处理冲突,输入关键字序列:
(10,24,32,17,31,30,46,47,40,63,49),构造哈希表,试回答下列问题:
①画出哈希表的示意图;
②若查找关键字63,需要依次与哪些关键字进行比较?
③若查找关键字60,需要依次与哪些关键字比较?
④假定每个关键字的查找概率相等,求查找成功时的平均查找长度。
(3)查找60,首先要与h(60)=60%16=12号单元内容比较,但因为12号单元为空,所以应当只比较这一次即可。
(4)asl=1/11(6+2+3×3+6)=23/11
(6)设有一组关键字(
9,01,23,14,55,20,84,27),采用哈希函数:
h(key)=key%7,表长为10,用开放地址法的二次探测法处理冲突。
要求:
对该关键字序列构造succ以关键字27为例:
h(27)=27%7=6(冲突)h1=(6+1)%10=7(冲突)(7)设哈希函数h(k)=3kmod11,哈希地址空间为0~10,对关键字序列(32,13,49,24,38,21,4,12),按下述两种解决冲突的方法构造哈希表,并分别求出等概率下查找成功时和查找失败时的平均查找长度asl
succ和aslunsucc。
①线性探测法;②链地址法。
aslsucc=(1+1+1+2+1+2+1+2)/8=11/8
aslunsucc=(1+2+1+8+7+6+5+4+3+2+1)/11=40/11
aslsucc=(1+1+1+2+1+2+1+2)/8=11/8aslunsucc=18/11
