21、e引导（1）because （因为）的用法：because通常表示直接的原因。because引导的从句表示直接而明确的原因和理由，表示按因果关系的推断，语气很强，用来回答why的问题, 一般位于主句之后。例：We couldnt go out because it was too cold. 因为天气太冷，我们不能外出。.for（因为）的用法：for是并列连词，引出的原因较间接，似乎是事后所想到的补充解释的理由，只陈述一般推断的理由，不一定表示产生结果的必然原因，主要放在两个并列句之间。例：It must be morning for the birds are singing.一定是清晨了，

22、因为鸟儿在叫。注意：下列情况下只能使用because:在回答why的问句时；在用于强调句型时；被not所否定时。（2）as和since（因为）的用法:表示已经知道的原因时用as或since,即某种原因在说话人看来已经很明显，或已为听话人所熟悉。since要比as正式一些，它们通常被置于语句之前。Seeing all of the children already seated, he said,“Since everyone is here, lets start.”Step 2: Consolidation:Get Ss to finish exercise on page 104.Step

23、 3 Presentation of the different usage of Because of and becausebecause与because of的用法比较从词性上看because 是连词，其后接句子；because of 是复合介词，其后接名词、代词、动名词、what 从句等。如：I didnt buy it because it was too expensive. 我没有买是因为它太贵了。He is here because of you (that). 他为你(那事)而来这里。He lost his job because of his age. 由于年龄关系他失去了

24、工作。We said nothing about it, because of his wifes being there. 因为他妻子在那儿，我们对此只字未提。He knew she was crying because of what he had said. 他知道她哭是因为他说的话。注意：because of 之后可接 what 从句，但不能接 that 从句或没有引导词的句子。如：他因病未来。误：He didnt come because of he was ill.误：He didnt come because of that he was ill.正：He didnt come

25、because he was ill.正：He didnt come because of his illness.比较以下同义句：他离开了这家公司，是因为老板在会上讲的话。正：He left the company because of what the boss said at the meeting.正：He left the company because of the thing that the boss said at the meeting.我不能因为有个家就停止斗争。正：I cant stop fighting because I have a family.正：I cant

26、 stop fighting because of having a family.从用法上看because 所引导的从句除用作原因状语外，还可用作表语。如：It is because he loves you. 那是因为他爱你。而复合介词 because of 所引导的介词短语通常用作状语而不用作表语。如：他因雨缺席。误：His absence was because of the rain.正：His absence was due to the rain.正：He was absent because of the rain.但是有时若主语是代词(不是名词)，也可以用 because o

27、f 引出的短语作表语。如：It is just because of money. 那只是因为钱的原因。That was because of his sickness. 那是因为他生病的原因。Step 4: Summarize what we have learned today.Step 5: Homework:1.
