一、语法定义
本篇汇总八年级上册所有题型高频错误知识点,划分八大类别,每一类都包含错误句子、译文、
正确句子以及详细错误原因分析,规避单选、句型转换、连词成句、写作里常见失误。
类别一:spend/take/cost/pay四个花费动词混用错误
错误句子:The book spends me ten yuan.
译文:这本书花了我十元钱。
正确句子:I spend ten yuan on the book.
解析:spend主语只能是人,物品作主语要用cost。
错误句子:I get to home early.
译文:我到家很早。
正确句子:I get home early.
解析:home是地点副词,必须去掉介词to。
类别二:too/also/either三者混用错误
错误句子:I don’t like math, too.
译文:我也不喜欢数学。
正确句子:I don’t like math, either.
解析:否定句句末表示“也”只能用either,too只用在肯定句句末。
错误句子:Because it rained, so I stayed at home.
译文:因为下雨,所以我待在家里。
正确句子:Because it rained, I stayed at home.
解析:because和so不能同时出现在一句话中,二者保留其一即可。
类别三:形容词、副词原级和比较级使用错误
错误句子:Tom is more tall than his brother.
译文:汤姆比他弟弟高。
正确句子:Tom is taller than his brother.
解析:tall是单音节单词,比较级直接加er,不能加more。
错误句子:This book is as more interesting as that one.
译文:这本书和那本书一样有趣。
正确句子:This book is as interesting as that one.
解析:as…as结构中间只能用形容词、副词原级,不能使用比较级。
类别四:to do与doing非谓语动词搭配错误
错误句子:I want buying a new pen.
译文:我想要买一支新钢笔。
正确句子:I want to buy a new pen.
解析:want后面固定搭配to do不定式,不能接doing形式。
错误句子:She enjoys to listen to music.
译文:她喜欢听音乐。
正确句子:She enjoys listening to music.
解析:enjoy后面只能接动词ing形式。
错误句子:He is good at play basketball.
译文:他擅长打篮球。
正确句子:He is good at playing basketball.
解析:介词at后面的动词必须变为ing形式。
类别五:主将从现时态规则使用错误
错误句子:If it will rain tomorrow, we will stay at home.
译文:如果明天下雨,我们就待在家里。
正确句子:If it rains tomorrow, we will stay at home.
解析:if引导条件状语从句,要用一般现在时代替将来时,主语it是三单,动词加s。
错误句子:When he will arrive, I will tell him the news.
译文:他到来时我会告诉他消息。
正确句子:When he arrives, I will tell him the news.
解析:when引导时间状语从句,遵循主将从现,从句不用将来时态。
类别六:一般过去时句式结构错误
错误句子:He didn’t went to the park yesterday.
译文:他昨天没有去公园。
正确句子:He didn’t go to the park yesterday.
解析:didn’t后面必须把动词恢复成原形,不能使用过去式。
错误句子:Did he went to school?
译文:他去上学了吗?
正确句子:Did he go to school?
解析:句首出现助动词Did,后面实义动词要用原形。
错误句子:They was at home last night.
译文:他们昨晚在家。
正确句子:They were at home last night.
解析:主语they是复数,be动词过去式要用were。
类别七:always/often/usually频率副词位置错误
错误句子:She always is busy.
译文:她总是很忙。
正确句子:She is always busy.
解析:句子有be动词时,频率副词要放在be动词后面。
错误句子:Always he gets up early.
译文:他总是早起。
正确句子:He always gets up early.
解析:频率副词不能置于句子开头,放在主语之后、实义动词之前。
错误句子:How long does he exercise?
译文:他多久锻炼一次?
正确句子:How often does he exercise?
解析:对动作发生的频率提问,固定疑问词是How often,How long用于询问时长。
类别八:写作句式高频扣分错误
错误句子:Because I like reading, so it makes me relaxed.
正确句子:I like reading because it makes me relaxed.
解析:because与so不可连用,是写作高频扣分点。
全册高频易错总提醒
1.because和so不可连用,although和but也不可连用;
2.as…as结构中间只用单词原级,看见than才使用比较级;
3.did、didn’t出现之后,所有实义动词必须变回原形;
4.if、when引导从句,从句不用will,只用一般现在时;
5.介词后面的动词一律要用ing形式;
6.频率副词放在be动词之后,实义动词之前;
7.对频率提问只用How often,不能用How long。
知识要点总结:
八年级上册易错点集中在连词连用禁忌、非谓语固定搭配、主将从现时态规则、一般过去时否定疑问句结构、
副词摆放位置这五大板块。大部分错误都是句式结构记忆不牢固造成,牢记连词不能混用、助动词后动词还原、
从句时态三大核心规则,就能避开绝大多数错误。
