2022初二英语知识点总结梳理1.由that引导，由于that没有任何意义，也不充当任何句子成分。因此that在非正式文体中可以省略。这类宾语从句通常表达一种陈述意义。e.g.Hetoldme(that)hewouldgotoWuhan.Tomsays(that)hemuststudyhard.Shetoldme(that)shewasastudent.(1)如果由and连接两个并列的宾语从句时，第二个that则不能省略。e.g.ShesaidshelikedEnglishverymuchandthatshedidn’tlikemathatall.(2)常接that引导的宾语从句的谓语动词有：believe,expect,explain,feel,hear,hope,imagine,prefer,promise,report,say,see,tell,think,understand,warn,wish等。2.由连接代词或连接副词who,whose,what,which,when,where,how,why引导，含有“谁、什么、哪个、什么时候、什么地方、怎样、为什么”等特殊疑问意义。e.g.Doyouknowwhothey’retalkingabout?Canyoutellmewhatthey’relookingfor?Idon’tknowwhereshehasgone.Iwonderhowshecanfindus.Shedidn’ttellmewhereherhometownwas.3.由从属连词whether和if引导，含有“是否，能否，对否，有否”等一般疑问意义。e.g.SheaskedmeifIcouldhelpher.JimwantedtoknowwhetherIhadtakenhisEnglishbook.Pleasetellmewhetheryoucancomeornot.在这类宾语从句中要注意两点：(1)if引导宾语从句和状语从句的区别if引导宾语从句时意为“是否”，从句中该用什么时态就应用什么时态。if引导条件状语从句时意为“假如”，从句中应用一般现在时代替一般将来时。e.g.Shewantedtoknowifyouwereateacher.Idon’tknowiftheletterisyours.They’llgoboatingifitisfinetomorrow.I’llgiveittoherifshecomesnextweek.(2)if引导宾语从句时多数情况下可以与whether互换，但如果要突出“究竟是……还是不……”这层意思时，通常用whether，并在后面的加上“ornot”，即一般要选择whether构成whether…ornot的结构。e.g.Pleasefindoutwhetherthemoneyishisornot.Letmeknowwhetheryoucancomeornot.Iwanttoknowwhetheryoucanhelpmeornot.八年级英语知识点v+todo/doing1.trytodosth尽量做某事，努力做某事hetriestofinishhishomeworkTrynottodosth尽量不做某事hetriesnottohurthisfriends’feelings。Trydoingsth尝试做某事。Hetriedwashinghishairwithanewshampoo。2.meantodosth有意做某事Ididn’tmeantohurtyou我不是有意伤害你的。Meandoingsth意味着、beinggoodtoherdoesn’tmeanlovingher对她好并不意味着爱她。3.startdoingsth.开始做某事=starttodosth(begin)Heusuallystartscookingat6intheeveningwhenhismotherisnotathome.当他妈妈不在家时，他通常在晚上6点钟就开始做饭。4.停止做某事theteacheriscoming，letsstoptalking.停下来做某事ifyouaretired,youcanstoptorest.八年级上册英语期中知识点总结1.Ittakessb.sometimetodosth.花费某人某些时间去做某事,例如：Ittakesmetwentyminutestogettoschoolonfooteverymorning.每天早晨我步行到学校要花费二十分钟。Itwilltakethreehourstofinishthework.完成那项工作需要花费三个小时。2.dependv.依靠，依赖depend(常与on,upon连用)视情况而定Italldependsonhowyou
