 連詞 1  ①并列連詞（表示并列、選擇、轉(zhuǎn)折、因果 ）→并列句（and, or, but, so,以及與此相關(guān)的復合并聯(lián)連詞both ... and ..., either ... or ..., neither ... nor ... , not only...but also..） ②從屬連詞（引導時間、條件、讓步、原因、目的、結(jié)果→狀語從句） 時間狀語: when , while, before, until, after, since(自從), once（一旦..就）as soon as一...就... 條件狀語: if, unless, as long as（只要...就） 讓步狀語: although, though（不與but連用） 原因狀語: because, since(既然，因為)，as, for 目的狀語: so that, in order that結(jié)果狀語: so...that, such...that(如此...以至于...)  2 1. 時間狀語從句通常不用一般將來時，可采取“主將從現(xiàn)、主祈從現(xiàn)、主情從現(xiàn)”。 As soon as I reach Canada, I will ring you up. We will leave here before he comes back. 2.when,while,“當...的時候”，可遵循：when過主行，while行主過，when過主過，while行主行。但并不是只能遵循此規(guī)律。 I was cooking when he knocked at the door. While the child was playing with his toy, his parents were reading. Love your parents while they are alive.Don't wait until it is too late. Don't make any noise while others are reading. 3.條件狀語從句 if, as long as , unless也可以遵循主將從現(xiàn)。 If he comes, Helen will be very happy. As long as you return the book on time, you can borrow it. He won't go unless you invite him. 4.從屬連詞because不能與并列連詞so連用。 5.注意as long as 與as soon as的區(qū)別。 6.because與since與as的區(qū)別：①because:常用回答why的問句，不能與so連用。表示直接的原因或理由，重點在從句。 I bought the house because it is cheap. ②since “既然，因為”，強調(diào)已知的事實，不需要強調(diào)原因，通常放句首，重點在主句。 Since he can't answer the question, we'd better ask someone else. ③as與since類似，不需要用because強調(diào)原因，主從句具有同等重要性。 Mother began to worry about my brother as it was getting darker. 3 1.Victoria, hurry up! _____we can't arrive there on time.
