He with his friend is going to 为什么用is

heistalkingwithhisfriend对划线部分提问.~

he is talking with his friend
对 his friend提问：
Who is he talking with?
对 is talking 提问：
What is he doing with his friend?
对 is talking with his friend提问：
What is he doing?

这个学期,可以表示一段连续的时间,用进行时表动作在某段时间一直持续,一般现在时无此用法.

因为 在 he with his friend 的结构中 主语是 he
类似用法如：together with，as well as
【亮点来喽】
就远原则：谓语动词与前面主语一致 　　
代表词汇：as well as；（together/along/combined）with；rather than；except；besides；but；including；in addition to；apart from, like, as much as, no less than, 　　
E.G： 　　
Nobody but two students is in the classroom.除了这两个学生，没有人在教室 　　
Everybody except you is down on me. 除了你，大家都看不起我。 　　
A woman with two children has come. 一位妇女带着两个孩子已经来了。 　　
John, rather than his roommates, is to blame. 约翰，而不是他的室友，应该受到责备。
Jim, together with his classmates, has seen the film. 吉姆和他的同学都看过这部电影。 　　
My father, no less than I, is a base-ball fan. 我的父亲不亚于我也是个棒球迷。 　　
The son, as well as his parents, wants to go there. 不但儿子想去那儿，而且他的父母也想去。
The teacher, as well as the students, is interested in the activity. 老师也和同学们一样对这项活动有兴趣。

with 是伴随状态，主语只是He，这句话也可以写成He is going to XX with his friend.

有with的时候谓语是根据with后面的词来用

用with的话是就远原则，动词由he来决定
（百科）代表词汇：as well as；（together/along/combined）with；rather than；except；besides；but；including；in addition to；apart from, like, as much as, no less than,

with his friend 是插入语，主语是he 谓语用单数is
个人见解，希望能够帮助到您，欢迎采纳O(∩_∩)O~

with 作伴随状语，主语是his，第三人称单数所以用is
