It was five years _he finished his research. It was five years later _he finished his research. It was 5 oclock _ he got home. It was at 5 oclock _ he got home.,when,that,since,before,that,till (until) 和nottill (until),1） till (until):主句谓语动词必须是持续性的，意思是“到为止“如： He remained there till/until she arrived. 2） nottill (until): 主句谓语动词必须是短暂性的，意思是“直到才”如： She wont go to bed till/until he returns home. 3） notuntil还有强调式和倒装式： 强调句： It is not until he returns home that she will go to bed. 倒装句： Not until he returns home will she go to bed.,条件状语从句,常见的从属连词有： if, unless, as/so long as , as/so far as, on condition that , in case(万一) , the more, the more等。如：,Mother asked me to take more money _ something unexpected should happen. A. in case B. so that C. in order that D. when,in case 起连词作用，用以引导状语从句，主要有两种意思：一是表示条件，意为“如果”、“万一”；二是表示目的，意为“以防”、“免得”。,(1) _ I forget, please remind me about it. A. In case B. So that C. In order that D. When (2) Take your umbrella just _ it rains. A. in case B. so that C. in order that D. when,“Shall Mary come and play computer games?” “No, _ she has finished her homework.” A. when B. since C. unless D. as soon as,此句为省略句，答句句首的 No 表明其后省略的是一个否定句，全句补充完整为：She cant play computer games unless she has finished her homework.,(1) “Would you mind my sitting here with you?” “No, _ you arent too noisy.” A. when B. if C. unless D. as soon as (2) “Will he agree to come to join us in the work?” “No, _ we promise him more money.” A. when B. unless C. until D. as soon as,原因状语从句,常见的从属连词有： because, since, now that , as等。,注意because, since, as和for的区别：,）because的语气最强，它引导的从句比主句更重要，从句的位置可前可后；例外回答why的问句必须使用because。如： -Why were you absent from the meeting yesterday?-Because I was ill. 2)since和now that意思是“既然”，语气仅次于because,从句的位置一般在前。如： Since everybody is here, lets begin our meeting 3)as的语气比since更弱，意思是“由于”，从句的位置可前可后。如：As you didnt turn up at yesterdays get-together, we missed you very much ）*for也有“因为”之意，但for是并列连词常用来来补充说明原因或用来表示推断的依据，前面常带逗号。如： It must have rained last night, for the ground is wet,1.
