解题思路：科学记数法的表示形式为a×10n的形式，其中1≤|a|＜10，n为整数．确定n的值时，要看把原数变成a时，小数点移动了多少位，n的绝对值与小数点移动的位数相同．当原数绝对值大于10时，n是正数，当原数的绝对值小于1时，n是负数．有效数字的计算方法是：从左边第一个不是0的数字开始，后面所有的数字都是有效数字．

2 260=2.260×10³≈2.3×10³．
故选A．

本题考点： 科学记数法与有效数字．

考点点评： 本题考查了科学记数法、有效数字两个概念．科学记数法是指把一个数写成a×10n（其中1≤|a|＜10，n是整数）的形式．本题中10的指数就是原数的整数位数减去1．有效数字则是左边第一个不是0的数起到精确到的位数止，只与a有关，取舍时要注意遵循四舍五入的原则．

解题思路：本题考查学生对物理变化和化学变化的确定，判断一个变化是物理变化还是化学变化，要依据在变化过程中有没有生成其他物质，生成其他物质的是化学变化，没有生成其他物质的是物理变化．

A、海水晒盐是利用阳光和风力使水分蒸发，没有新的物质生成，属于物理变化，故A正确；
B、太阳能光解水制氢气，把水分解生成了氢气，说明有新的物质生成，属于化学变化，故B错；
C、植物的光合作用吸入二氧化碳和水，释放出氧气和有机物，有新的物质生成，属于化学变化，故C错；
D、三氧化硫溶于水形成硫酸型酸雨是三氧化硫与水反应生成硫酸，有新的物质生成，属于化学变化，故D错．
故选A．

解题思路：（1）设搭配一个A种造型所需甲种花卉盆数需要x，乙种花卉盆数为x2，搭配B种造型需甲x1.6，需要乙种花卉2•x2+10，根据搭配一个B种造型共需甲、乙两种花卉140盆，可列方程求解．（1）摆放50个园艺造型所需的甲种和乙种花卉应＜现有的盆数，可由此列出不等式求出符合题意的搭配方案来；（2）根据两种造型单价的成本费可分别计算出各种可行方案所需的成本，然后进行比较；也可由两种造型的单价知单价成本较低的造型较多而单价成本较高的造型较少，所需的总成本就低．

（1）设搭配一个A种造型所需甲种花卉盆数需要x，
[x/1.6]+2•[x/2]+10=140
x=80，
搭配搭配一个A种造型所需甲种花卉盆数需要80，乙种花卉盆数为40，搭配B种造型需甲50，需要乙种花卉90．
（2）设搭配A种造型x个，则B种造型为（50-x）个，依题意得


80x+50(50−x)≤3490
40x+90(50−x)≤2950，
解这个不等式组得

x≤33
x≥31，
∴31≤x≤33
∵x是整数，
∴x可取31，32，33
∴可设计三种搭配方案
①A种园艺造型31个B种园艺造型19个
②A种园艺造型32个B种园艺造型18个
③A种园艺造型33个B种园艺造型17个．
（3）由于B种造型的造价成本高于A种造型成本．所以B种造型越少，成本越低，故应选择方案③，成本最低，最低成本为
33×800+17×960=42720（元）
最低成本为42720元．
