D
It’s eight o’clock说明是现在 、用be doing 而students是复数 用are 选d
++++++
listen 表示现在进行时（look也是一样）baby 单数、选C
+++++++++
同上、twins是复数、选A
+++++
Don’t talk here表明是现在进行时、parents是复数、选B
+++++++++
介绍Tom这个人、他一直在工作、他的姐姐、妹妹也是一样、是长期性的
所以是一般现在时、用动词原形 前者单数、后者复数 、、选C
+++++++++++++
也是长期性的、而且这里的who是一个人、因为最好 ,所以只有一个 .是第三人称单数,选B
++++++++++++
every day.一般现在时、Mrs Read 第三人称单数、选C
++++++++++++
often和every day表示频率、是一般现在时的特征、we是复数 选A
+++++++++++++++++++
inthe morning 也是一般现在时（这里是这样、不排除过去时的可能）
she 是第三人称单数、选B
打了很久呢、、把分给我吧、

C
后面有now，用进行时，没有具体时间限制，一般用一般现在时

c 现在进行时是正在进行的动作

C. is singing
现在谁在那里唱歌？
be doing 是进行时

C is singing 现在进行时
A, B D 三个语法都错误
A singing 不能独立用，要加is/are/was/were等
B are sing 不合语法，应作are singing
D sing 由於主语是Who，要用sings 三单

选C
先看Who,通常Who看作单数形式，后面的谓语应该是单数形式。
再看now这个时间语态，用现在进行时，be doing sth.
所以，应该填的选项是is singing.

c

C
now是现在进行时的时间状语
