Answer 1

There’s a flower market near my estate. I always go there after work. There’re many kinds of flowers. I know only __ 1__ names of them. I don’t always buy fresh flowers. They are too expensive. In spring and summer, flowers are a little _ _2__ . Because the weather is warm. Flowers are easy to grow. So there are _ _3__ flowers. Also it’s very hard for __4__ to keep the flowers overnight in this kind of weather. So usually, they sell their flowers at a lower price ___5__ about five o’clock. That’s the time I go to buy some.

（ B ）16. A. some B. more C. much D. fresh
（ C ）17. A. us B. the farmers C. the flower sellers D. buyers

1、若 | x | = 1，| y | = 2，请计算出 x + y的所有可能值。

因为|x|=±1 |2|=±2 所以要分情况：x=1 y=1时：原式=2
x=-1 y=1时原式=0 x=-1 y=-1时：原式=-2

2、已知有理数m、n互为倒数，a、b互为相反数，c的绝对值为3，求 27分之5*mnc2+（a+b)c的6次方 的值是多少？

这题实在太长，我有空再来补吧。。

3、有两个工程队，第一队有50人，第二队比第一队少12人，因任务需要，要求第一队的人数比第二队人数多2倍，问需要从第二队抽调多少人去支援第一队？

第二队：50-12=38（人）
解设：要抽x人

50+x=2（38-x）

解方程。。

4、小杰，小明两人做加法运算，小杰将其中一个加数后面多写了一个零，得和是1275，小明将同一个加数少写了一个零,得和是87，求原来两个加数.
不会。。

5、一个两位数，个位上的数字比十位的数字大3倍多1，如果把十位上的数字与个位上的数字对调,所得新数比原数大45，求原来的两位数。

不会。。

唉。。

Answer 2

英语
14~18 BDBCB
1~8 DDCCBCBC

数学
1 答案3，-3, 1，-1
2 m=1/n a=-b |c|=3代入5/27*m*(1/m)+(a+-a)*3^6=5/3
3 设要调x人 乙队人数50-12=38 列方程（50-x）=3(38-x) 答案x=16
4 答案120和75
5 设十位数字为x 那么个位数字就是3x+1
把十位上的数字与个位上的数字对调,所得新数比原数大45
所以10（3x+1）+x=10x+3x+1+45
x=2
所以十位数字为2 个位数字为3x+1=7
这个两位数为27

Answer 3

英语就不做了，看看前面的就行，数学我简单说下过程
1.x、y分别为正负1与正负2有四种情况
可得x+y有四种情况正负1与正负3

2.由题意mn=1。a+b=0，c²=9，则27分之5*mnc²+（a+b)c=5/3
它的6次方为15625/729

3.第2队人数38人，则总人数为88人，要求第1队人数比第2队多2倍就是说第1队人数为第2队人数3倍，则第2队人数为88/4=22人，即调16人去1队

4.设原来两加数分别为x和y
则10x+y=1275，x/10+y=87，解得x=120，y=75

5.设十位数字为x，则原两位数为14x+1，调换后两位数为41x+10
41x+10-（14x+1）=45
解出来的x不是整数，看来题出错了

如果是个位上的数字比十位的数字大3倍多2，则可以解出x=1

1、x=-1,1
y=-2,2
x+y=3,-3,1,-1

2、由题mn=1,a+b=o,c2=9
原式=45+0=45

3、50+50-12=88
50-12-88/4=16人

4、（1275-87）/99*10=120
87-120/10=75
原两加数为12，75

5、设十位数字为x
10x+3x+1-(3x+1)*10-x=45
x=2
原两位数为27
第五题“个位上的数字比十位的数字大3倍多1”
应该是“个位上的数字比十位的数字的3倍多1”吧。

一下子出这么多题目，人都被你吓怕了。

Answer 5

A B B A A
D D C B B C B D
数学：1、x=1或-1，y=2或-2，则x+y=1，-1,3，-3。
2、mn互为倒数，则m*n=1，ab互为相反数，则a+b=0。又可知c平方为9。分别代入，则可得到结果。
3、第二队人数：50-12=38。 设从第二队中抽出x个人，则：（50+x）=3*（38-x）,解方程，得到x=16。
4、设x、y，（x*10）+y=1275；（x/10）+y=87，x、y分别为120和75。
5、原十位数为x，个位为y。y=3*x+1;(10*y+x)-(10*x+y)=45。x、y为2和7。
