八年级上10单元知识点 1. if引导的条件状语从句 ①If意为“如果”，引导条件状语从句时，既可放在主句前面，也可放在主句后面。若if条件句放在句首，从句后面要加逗号与主句隔开。 Eg：If you go there, I’ll go, too.“如果你去那儿，我也会去。”My mother will take me to the park if she is free.“如果我妈妈有空，她就会带我去公园。” ②时态运用：在含有记引导的条件状语从句的主从复合句中，主句为下列情形之一的，条件状语从句要用一般现在时。 A.主句是一般将来时。Eg: If he comes, he will bring his violin.“如果他来，他就会带来他的小提琴。” B.主句谓语含有情态动词 may/might/can/must/should 等。Eg: If you want to lose weight, you must eat less. “如果你想减肥，你必须少吃肉。” C.主句是祈使句。Eg：If you are not strong enough, please don't take part in such an activity. “如果你不够强壮，请不要参加这种活动” ③句型转换 A. 借助“祈使向+and/or ＋ 句子（一般将来时）”这一句型来转换。其中，在句意上and 表示顺承;ot 表示转折，意为“否则” Eg: If you study hard, you'll pass the exam easily.= Study hard, and you'll pass the exam easily. “努力学习，你将很容易通过考试。” B. 借助 without 或 with 来转换条件状语从句。Eg: If there is no water, fish will die.= Fish willdie without water. “如果没有水，鱼将会死。” If you help me, I'll finish the work soon.= With your help, I'll finish the work soon. “如果你帮助我，我将很快完成工作。” 2. have a great/good/happy/wonderful time = enjoy oneself = have fun“玩得高兴，过得愉快”后面的动词用ing形式。Eg：We always have a great time talking to each other.“我们相互交谈时总是过得很愉快。” 3. talk （v）谈论 ①talk to/with sb“与……交谈”Eg：I often talk with my best friends.“我经常和我最好的朋友交谈。” ③talk about…“谈论……”Eg：We often talk about the future.“我们经常谈论未来。” 4. take a/an/the+交通工具+to +地点=go to+地点+by+交通工具。 Eg：I’ll take the bus to the party.= I’ll go to the party by bus.“我将会乘公交车去参加派对。” 5. meet（v）遇见 meeting（n）会议、集会 Have a class meeting“开一次班会”；have a parents' meeting“开家长会” attend the meeting“参加会议”；sports meeting “运动会” 6. half（adj）“一半的”用于冠词前面；（n）“一半”half of…“一半的……”作主语时，谓语动词由of 后的名词决定。 Eg：Half of the water in this bottle is wasted.“瓶子里一半的水被浪费了。” Half of the apples in this basket are wasted.“篮子里面一半的苹果被浪费了。” 7. happen（v）发生 ①Sth happen +时间/地点短语“某地/某事发生了…” ②Sth happen to sb“某事发生在某人身上”Eg：A traffic accident happened to a stranger yesterday. “昨天一个陌生人发生一起交通事故。” ③Sb happen to do sth“某人碰巧做了某事”Eg：I happened to see my best friend on the supermarket. “我碰巧在超市遇见了我最好的朋友。” 8. a good time to
