While he was doing his homework, the telephone rang. As he walked along the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： Ill ring you up as soon as I get to New York. I will tell him everything when he comes back. He wont believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是"一直到时'，谓语动词只能用延续性动词。如果主句用否定式，其含义是"直到才', "在以前不', 谓语动词可用瞬间动词。例如： The young man read till the light went out. Lets wait until the rain stops. We wont start until Bob comes. Dont get off until the bus stops. 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow? Dont leave the building unless I tell you to. (2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： Ill help you with your English if am free tomorrow. He wont be late unless he is ill. (3)"祈使句 + and (or)+ 陈述句' 在意思上相当于一个带有条件状语从句的复合句。例如： Hurry up, or youll be late. =If you dont hurry up, youll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didnt come to school because he was ill. As it is raining, we shall not go the zoo. Since you cant answer the question, Ill ask someone else. (2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如： -Why arent going there? -Because I dont want to. As he has no car, he cant get there easily. Since we have no money, we cant buy it. (3)because和so不能同用在一个句子里。 初中英语知识点总结归纳：一般现在时 英语语法一般现在时表示常常性或习惯性的动作，或表示现在的特征或状态。那么，英语一般现在时的句子结构和语法特点是怎样的呢?下面为您讲解一下。 其动词形式是：动词原形(只有第三人称单数作主语时除外，要加-s)其疑问句和否定句需要用助动词do或does 1) 肯定句用行为动词原形表示 They get up very early every morning. 他们每天早晨起来很早。 I visit my grandparents four times a month. 我一个月去看望祖父母四次。 2) 否定句用dont + 动词原形来表示 We do not go shopping on Sundays. 我们周日不去购物。 I dont think you like this colour. 我想你不喜欢这个颜色。 3) 一般疑问句则是把助动词do提前至句首，后面动词用原形。回答时，肯定用 "Yes, 主语+do'否定句用 "No, 主语+dont'。 Do they go to school at seven oclock? 他们七点去上学吗? -Yes, they do. -Do you like this skirt? 你喜欢这条裙子吗? -No, I dont. 不，我不喜欢。 一般现在时用来表示常常的或习惯性的动作，常与以下的时间状语连用：often 常常，always 总是，sometimes 有时，usually 通常，every day/ week 每天/ 周等。 He usually goes to school by bike. 通常他骑车上学。 I visit my grandparents every week. 我每个星期都去看祖父母。 She is always late for class. 她总是上课迟到。 My parents and I sometimes go out to eat. 我和父母有时出去吃饭。 It often rains here. 这儿经常下雨。 主语为第三人称单数时的一般现在时 一般现在时态，当主语为第三人称单数时，谓语动词也要是第三人称单数，后要加-s或-es。 He likes reading at night. 他喜欢夜里读书。 She usually goes to school by bike. 她平时骑车上学。 The little cat drinks milk every day. 小猫每天都喝牛奶。 转换成否定句要加doesnt，其后的动词用原形。 Kelly doesnt get up early on Saturdays and Sundays. 凯丽星期六星期天起床不早。 He doesnt feel well today. 他今天感觉不舒适。 转换成一般疑问句，句首用Does，其后的动词用原形。 Does he have lunch at school? 他在学校吃午饭吗?
