被动 与时态下面有两篇短文,― ―处为填入的答案,括号内的为提示语,主要是考查被动语态,请帮我分析一下 同一篇文章里要填入不同的时态,有时候用一般过去时被动,有时用一般现在时被动
1.被动我懂得用,主要帮我分析填入处为什么用那个时态
-被动语态你懂,我就不解释了,关于时态方面的问题：
一般过去时：事情发生在过去,而且现在已经结束了.
比如说,Many peoeple died in the war. 战争中死了很多人.死这个动作是发生的过去,而且是个瞬间完成的动作,不是一直死,不是一个延续的动作.
现在完成时：事情在过去就已经发生了,这个动作一直延续到现在或者是这个动作的影响一直延续到现在.
比如说,A website __has been started__ (start) by the villagers to tell people about the problem and how to solve it. 村民建设起网站,告诉人们这个问题和如何解决.网站是以前就建立了,而且目前仍然在使用.所以一定要用现在完成时.
一般现在时：就是目前发生的事情,或者是经常发生的事情.
比如说,I'm a student. 我现在是个学生.I usually get up at 7am. 我通常是早上7点起床.
2. already also 的位置一定要放那里吗、 可以调去其他位置吗 如果不行 为什么
-这个是一个习惯用法.记住就可以了.
3.我知道 It is said to be 是固定短语 但请问有没有It was said to be呢
-也有,一般都在文学作品中出现.就平时生活的写作时,用一般现在时就可以了.
关于你补充的问题：
Guilin _has been visited__(visit) by so many tourists that some of its cultural sites __are not well protected__(not well protect).
中文的意思是：由于很多人去参观桂林,以至于桂林的一些文化古迹都没有被好好的保护起来.
很明显,这是个被动语气呀.所以必须用被动语态,而且说的是现在的情况,所以用一般现在时,are not well protected.

一般already放have后面,做题先确定时态,再分析语态,时态可据前后文,或时间状语eg:already就是完成式标志,或依据主从句的谓语
