You may have heard some respectable elders say, “It’s not what you want in this world, but what you get.”

Psychology teaches that you do get what you want if you know what you want and want the right things.

You can make a mental blueprint of a desire as you would make a blueprint of a house, and each of us is continually making these blueprints in the general routine of everyday living. If we intend to give a dinner for friends, we plan the menu, make a shopping list, and decide which food to cook first, and such planning is essential and necessary for any type of meal to be served.

Similarly, you can make a blueprint for your could-be-job, take a sheet of paper, and write a brief account of yourself. In making a blueprint for a job, begin with yourself, for when you know exactly what you have to offer, you can intelligently plan where to sell your service.

This account of yourself is actually a description of your working life and should include education, experience and references. Such an account is valuable. It can be referred to filling out standard application blanks and it is extremely helpful in personal interviews. While talking to you, your could-be employer is deciding whether your education, your experience and other qualifications will pay him to employ you, and your abilities must be displayed on an orderly and reasonably connected manner. When you have carefully prepared a blueprint of your abilities and desires, you have something exact to sell. Then you are ready to hunt for a job.

Get all the possible information about your could-be job. Make your eyes and ears open, and use your own judgment. Spend a certain amount of time each day seeking in the employment you wish for, and keep in mind: Obtaining a job is your job now!

H₂OH⁺ + OH^-，K_W=10^-14；

CH₃COOH    H⁺ + CH₃COO^－，K_a=1.8×10^-5；

K_SP[Mg(OH)₂]=1.8×10^-11、K_SP[Zn(OH)₂]=1.2×10^-17、K_SP[Cd(OH)₂]=2.5×10^-14

又已知：=2.2

下列说法正确的是[ ]

A．醋酸钠水解的平衡常数Kh随温度升高而减小；

B．0.5mol·L^-1醋酸钠溶液pH为m，其水解的程度（已水解的醋酸钠与原有醋酸钠的比值）为a；1mol·L^-1醋酸钠溶液pH为n，水解的程度为b，则m＜n、a＞b；

C．醋酸钠的水解的平衡常数K_h= K_W·K_a；

D．在某溶液中含Mg²⁺、Cd²⁺、Zn²⁺三种离子的浓度均为0.01mol·L^-1，向其中加入固体醋酸钠，使其浓度为0.9mol·L^-1，以上三种金属离子中只有Zn²⁺ 能生成沉淀。
