希望各位详细说出原因.

1.选A
其实我觉得A和B语法上都说得通,那么就看文意了
我记得是新2第一课波?? PRIVATE BUSINESS
好像就是那对情侣不停地讲话讲话,文章作者已经完全没有办法看电影了,就提出抗议,一开始他们不理他,后来作者说他听不到(电影对白)了!!!那对情侣却说:这不关你的事!!

2.选D
in front of 是表方位的,在什么什么的前面
before也是表前面,但是通常和after连用
above也是表前面,但是通常和below连用
ahead of具有前瞻性了,通常指更抽象的

3.选B
writer既然是非常生气地(angrily)看这他们,那么他就一定是很不开心的
sad是伤心的意思
unhappy是不开心的意思...happy是开心快乐,前缀un表与之相反的意思
cross是脾气坏的意思,文中并没有提到作者本身脾气暴躁
pleased是高兴的意思,不符合文意

4.选D
just then是就在刚才,就在那时的意思
at once是立即的意思
immediately和at once 意思相近,都是立即马上的意思
again是再次的意思
只有at that moment是那时,在那个时候的意思,与题意相符


这样可以了吗??
