1,很显然,第一题基本上没人用D 你如果选择一般时,那这句话就是说 他从来说话都是这个样子 ,就没必要说明他现在悲伤了 你说是不是
2,for centuries 是个固定短语,几个世纪的意思 不是完成时后面跟的FOR,
3,题目都错了,WANT TO 后 还用GOT ,我本来还想选D,后来看看全面有个JUST NOW 只强调目前的动作,没办法 只能用B ,C 不可能,C 用的地方你要掌握语感,C 不可能出现在这种句子当中,只会再人强烈的表达 从以前到现在,或到过去的某个时间一直做的事情,一般不会用在仅仅形容一个动作上面
4,D 答案强调不久就要发生的事情,A 带有主观意愿,一般我们用WILL ,都是在主观的表达问题,其实我觉得才c也挺好啊,毕竟IF 后的句子是虚拟的嘛

1.就算选D也要用过去式啊！因为说的话是过去说的
2.有时要根据题意选答案的，这句不是表达的完成时
3.B就是过去进行时啊！表示过去一直坐在他的外套上
4.有时在if 表达中时主将从现，指主语用将来式，从句用一般现在时，这句话就是这样的
好好努力，加油...
