[理会]B､A､A､C｡引导原因连词,as/because/ since/ for的区别是:because语势最强,用来说明人所未知的原因,答复why提出的问题,可置于强调句中且其前可加修饰语; since是两边都知晓原因或颠末阐明而得之的原因,语气次之;for是并列连词,前用逗号离隔, 表逻辑推理或增补说明;as语气最弱,原因是显而易见的或已为人们所知,即已知原因,所引导的分句可置于句首｡
例7. Excuse me for breaking in, ______ I have some news for you.
[理会]C｡but和yet 是连词,可等同利用,但也有区别｡yet与and连用,组成and yet,但but却无此用法;在“Excuse me/I’m sorry/I hope you don’t mind…but”中,只用but,不消yet｡因为在暗示比较或对立时,but较为轻松自然;而yet却较为强烈,常出人意表;though作并列连词时,只能引导分句且其前须加逗号｡例:I’ll try to come, though I don’t think I shall manage it.

Whether we’ll go camping tomorrow depends on the weather.
