He was nearly drowned once.
-When was_______?
-_______was in 1998 when he was in middle school.
A that,it B this;this C this;it D that;this 这道题怎么看
选项是A
that是指示代词,指代【那件事】.it是代词,指代【时间】.
the letters和the letter这两个哪个是对的 我同学说这两个都是对的 不是特指就不能加s了吗?
the letters和the letter都对.the letters特指【复数】,“那些信件/那些字母”；the letter特指【单数】,“那封信/那个字母”it只可以代时间吗？能代别的吗it在此指代时间。it做代词还能指代天气、距离；还能指代this或that；还能做形式主语、形式宾语；还可以用于强调句型结构。
