求高手解答两题英语单选题（答好加分）

第一题：如果这句话说全了,是The meaning of the word "advise"is different from the meaning of the word 'insist.这里为了避免重复,the meaning需要一个代词来指代the meaning, 英语语法中规定,比较结构中,that指代单数可数名词或不可数名词,those指代复数可数名词,例如：The weather in Beijing is hotter than that in Harbin.北京的天气比哈尔滨热.这句话中that指代了不可数名词the weather.
第二题：这道题是考察虚拟语气中would rather的用法.这道题可以通过otherwise看出来,是和过去相反的事实.虚拟语气用退格,本应由watched变为had watched, 但是would rather中有情态动词,语法中规定,情态动词后要加动词原型,所以加在had watched 之前,就变成了would rather bot have watched.
我是英语老师,退格虚拟好多学生都不理解,怎么过去完成时变成了现在完成时,其实没有变,是因为加了情态动词的缘故.例如：could have done其实是could +had done,而情态动词需要加动词原形,就变成了could have done
不知你明白了没有,希望帮到你!
