如从句表示的原因不是确定的事实,就不能用since,通常用because.
Sinceeverybodyishere,let’sbeginourdiscussion.
Sinceyouseemtoknowthem,whydon’tyouintroducemetothem?
for是一个并列连词,由for连结的表原因的句子常看作并列句,它只提供一些补充说明或对前一个分句加以解释,不可前置。
与because不同的是:
because引导的从句位置可前可后,而for引导的分句只能后置,且往往须用逗号或分号与前一个分句分开。
Ididn’tgotoseehim,foraheavysnowwasfalling.
Thedayswereshort,foritwasnowDecember.
有时,for引起的从句并不表示原因,而是表示一种推断或解释,而because则不能。
Someoneinthehousemustbeill,foradoctorhasjustcomeout.
Hecouldn’thaveseenme,forIwasnotthere.

2）用下列短语引导:
seeing（that）“鉴于,既然”,considering（that）“考虑到”now（that）“既然”,inthat“因为”,not...because“不是因为”notthat……butthat“不是因为……而是因为,’
seeingthat与consideringthat同义,含义近似since,所引导的句子中心在主句,重在强调结果。
Seeingthattheweatherisbad,we’llstayathome.
Consideringthattheyarenewcomers,they’veaccomplishedalot.
nowthat的含义与since（“既然”）接近,区别在于:
since表示原先已存在的情况,而nowthat表示由于新情况的出现而促成某事发生。
Nowthatithasstoppedraining,let’sstartatonce.
Nowthatyouareallhere,let’strytoreachadecision.
inthat作“因为”解时,由于介词in的含义是指“在……方面”,有限制作用,因此多指由于某一方面的原因或理由,不能位于句首。
Ilikethecity,butIlikethecountrybetterinthatIhavemorefriendsinthecountry.
Icouldunderstandhispointofview,inthatI’dbeeninasimilarpositionmyself.
not...because意为“不是因为”,该结构中的not否定because。
Shedidn’tmarryyoubecauseyouhadmoney.
她不是因为你有钱才嫁给你。
Themachinedidn’tstopbecausethefuelwasusedup.
机器不是因为燃料耗尽才停下来的。
notthat...butthat作“不是因为……而是因为”解。
NotthatIdon’tlikethefilm,butthatIhavenotimeforit.
Hefeltabitworried,notthattheywerenotworkinghard,butthattheydidn’tpayenoughattentiontosafety.
