)(∨.∨)81.85.87.952003年,爷爷过生日时给吉儿出了一道题:爷爷实际年龄正好等于出生年份的4个数之和的4

按实际情况,爷爷一定是在19XX年出生.
设爷爷是在19XY年出生的.
则4*（1+9+X+Y）=2003-（1900+10X+Y）
40+4X+4Y=103-10X-Y
14X+5Y=63
且由题意得X,Y都是小于10的正整数.
易知X=2,Y=7.
2003-1927=76（岁）
答：爷爷今年76岁.
英语题：
1.The chicken looks like bird.中bird改为birds.
(没有my等物主代词修饰的单数名词前须跟冠词）
2.There are some milk in the glass.中are改为is.
(milk为不可数名词）
3..-How much is the book?
-Five yuans.中yuans改为yuan.(yuan不可数）
4.How much is the price of this bike?中How much改为What.
(price需用what提问,也可改为How much is this bike?）
5.There are two breads on the table.
改为There are two piece of bread on the table.
(bread为不可数名词,要说2个需加piece)
6.Mary has much good friends.中much改为many.
(much用于修饰不可数名词）
7.We often have noodles with breakfast.中with改为at.
(at breakfast,at lunch,at dinner为固定用法）
8.Would you like to have some chickens?中chickens改为chicken.
（chicken当鸡肉讲时为不可数名词）
9.John's hair are very long.中are改为is.
(hair在这里是不可数名词）
10.How many woman teachers are there in your school?
中woman改为women(woman +职业/man +职业变成复数形式时需变成
women+职业/man+职业,如men doctors,但紧限于man/woman,其他这类词则只改变后面的名词,如shoe shops,apple trees等）

英语题:
1.looks→look 2.are→is 3.yuans→yuan
4.可改为How much is this bike?
5.可改为There are two pieces of bread on the table.
6.much→many 7.with→for 8.chickens→chicken
9.are→is 10.woman→women

第一题
设是在19xy年出生，则
(1+9+x+y)*4=2003-10x-y
14x+5y=63
又因为x、y为小于10的自然数，所以尝试后可得x=2、y=7，即于1927年出生，76岁了
第二题
1、不知道
2、应该是is 不是are
3、应该是yuan，不是yuans
4、应该是What，不是how much
