21、e引導（1）because （因為）的用法：because通常表示直接的原因。because引導的從句表示直接而明確的原因和理由，表示按因果關系的推斷，語氣很強，用來回答why的問題, 一般位于主句之后。例：we couldn't go out because it was too cold. 因為天氣太冷，我們不能外出。.for（因為）的用法：for是并列連詞，引出的原因較間接，似乎是事后所想到的補充解釋的理由，只陳述一般推斷的理由，不一定表示產(chǎn)生結果的必然原因，主要放在兩個并列句之間。例：it must be morning for the birds are singing.一定

22、是清晨了，因為鳥兒在叫。注意：下列情況下只能使用because:在回答why的問句時；在用于強調句型時；被not所否定時。（2）as和since（因為）的用法:表示已經(jīng)知道的原因時用as或since,即某種原因在說話人看來已經(jīng)很明顯，或已為聽話人所熟悉。since要比as正式一些，它們通常被置于語句之前。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

23、.step 3 presentation of the different usage of because of and becausebecause與because of的用法比較從詞性上看because 是連詞，其后接句子；because of 是復合介詞，其后接名詞、代詞、動名詞、what 從句等。如：i didnt buy it because it was too expensive. 我沒有買是因為它太貴了。he is here because of you (that). 他為你(那事)而來這里。he lost his job because of his age. 由于年齡關

24、系他失去了工作。we said nothing about it, because of his wifes being there. 因為他妻子在那兒，我們對此只字未提。he knew she was crying because of what he had said. 他知道她哭是因為他說的話。注意：because of 之后可接 what 從句，但不能接 that 從句或沒有引導詞的句子。如：他因病未來。誤：he didnt come because of he was ill.誤：he didnt come because of that he was ill.正：he didnt

25、come because he was ill.正：he didnt come because of his illness.比較以下同義句：他離開了這家公司，是因為老板在會上講的話。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.我不能因為有個家就停止斗爭。正：i cant stop fighting because i have a family.正：i

26、 cant stop fighting because of having a family.從用法上看because 所引導的從句除用作原因狀語外，還可用作表語。如：it is because he loves you. 那是因為他愛你。而復合介詞 because of 所引導的介詞短語通常用作狀語而不用作表語。如：他因雨缺席。誤：his absence was because of the rain.正：his absence was due to the rain.正：he was absent because of the rain.但是有時若主語是代詞(不是名詞)，也可以用 beca

27、use of 引出的短語作表語。如：it is just because of money. 那只是因為錢的原因。that was because of his sickness. 那是因為他生病的原因。step 4: summarize what we have learned today.step 5: homework:1. if i find his phone number, i _ you. a. tell b. told c. will tell d. have told2. i will call you as soon as i _ the ticket to the foo
