（1）（3分）细绳的一端在外力作用下从t =0时刻开始做简谐运动，激发出一列简谐横波。在细绳上选取15个点，图中第一个图为t =0时刻各点所处的位置，图中第二个图为t =T/4时刻的波形图（T为波的周期）。在图中第三个图中画出t =3T/4时刻的波形图。

（2）（3分）在利用单摆测定重力加速度的实验中，下列说法正确的是：      。

A．把单摆从平衡位置拉开30°的摆角，并在释放摆球的同时开始计时

B．测量摆球通过最低点100次的时间t，则单摆周期为 t/100

C．用悬线的长度加摆球的直径作为摆长，代入单摆周期公式计算得到的重力加速度值偏大

D．选择密度较小的摆球，测得的重力加速度值误差较小

Habits，whether good or bad，are gradually formed when a person does a certain thing again.He is driven by some unseen force to do the same thing repeatedly, and then a habit is formed．Once a habit is formed，it is difficult，and sometimes impossible，to get rid of．It is therefore very important that we should pay great attention to the formation of habits．Children often form bad habits, some of which remain with them as long as they live older. Persons also form bad habits lasting as long as they live，and sometimes become ruined by them．

There are other habits which，when formed in early life，are of great help．Many successful men say that much of their success has something to do with certain habits in early life，such as early rising，honesty and so on．

Among the habits which children should not form are laziness，lying，stealing and so on．These habits are all easily formed．Unfortunately older persons often form habits which could have been avoided．

We should keep away from all these bad habits，and try to form such habits as will be good for ourselves and others.
