1.at first“刚开始的时候/起初”,它一般用于描述一件事情的发展的前后进程,而且强调事情发展的前后特点不一致,且用于过去时居多.
所以,其后经常会出现转折词but.
如：At first I thougt English hard to learn.But after my hard work,I find it's easy.
2.at the beginning of...意思是“在...刚开始的时候”,它只描述事情的起初情况,并不强调后来的情况与开始时相反,当然用but来表示后面情况相反也是可以的,但也可以表明事情发展的顺承/一致关系.
上述例句你用at the beginning (of...)也是可以的.
但下面的例句就不能用at first了：
At the beginning of the concert,fans were very excited.Later they were almost mad. 1.at first“刚开始的时候/起初”,它一般用于描述一件事情的发展的前后进程,而且强调事情发展的前后特点不一致,且用于过去时居多.
