总体概览
八年级上册的重点在于时态的深化（一般将来时、过去进行时）、情态动词的用法、比较等级以及更复杂的句型结构,词汇量和阅读写作能力的要求也相应提高。
核心语法知识点
一般将来时
除了 will + 动词原形,八年级上册重点学习了另一种表达将来的方式。
（图片来源网络，侵删）
- 结构：
be going to + 动词原形 - 用法：
- 表示事先经过计划、打算要做某事。
例句：I'm going to visit my grandparents this weekend. (我打算这个周末去看望我的祖父母。)
- 根据现在迹象，预测不久的将来要发生某事。
例句：Look at the dark clouds. It's going to rain. (看那些乌云，天要下雨了。)
- 表示事先经过计划、打算要做某事。
- 与
will的区别：be going to强调计划和意图。will强调意愿、临时决定或客观预测。- 计划：I'm going to buy a new phone. (我打算买部新手机。)
- 临时决定：The phone is broken. I'll buy a new one. (手机坏了，我买一部新的吧。)
情态动词
八年级上册重点学习了 must, could, should 的用法。
-
must (必须，一定)
（图片来源网络，侵删）- 表示义务或命令（主观上必须做）。
例句：You must finish your homework first. (你必须先完成作业。)
- 表示肯定的推测（肯定“一定”是）。
例句：He looks so tired. He must be ill. (他看起来很累，一定是生病了。)
- 否定形式
mustn't表示“禁止，不许”。例句：You mustn't play on the road. (你不许在马路上玩。)
- 表示义务或命令（主观上必须做）。
-
could (能，可以)
（图片来源网络，侵删）- 是
can的过去式，表示过去的能力或许可。例句：When I was five, I could swim. (我五岁的时候会游泳。)
- 用于提出委婉的请求或建议。
- 例句：Could you please help me? (你能帮帮我吗？) 比
Can you...?更礼貌。
- 例句：Could you please help me? (你能帮帮我吗？) 比
- 是
-
should (应该)
- 表示建议或劝告。
例句：You should eat more vegetables. (你应该多吃蔬菜。)
- 表示推测（可能性比
must小）。例句：He left his home at 8 a.m. He should be in Beijing now. (他早上8点出发了，现在应该在北京了。)
- 表示建议或劝告。
比较等级
-
原级:
as + 形容词/副词原级 + as(和...一样)- 例句：Tom is as tall as his brother. (汤姆和他哥哥一样高。)
not as/so + 形容词/副词原级 + as(不如...)- 例句：This book is not as interesting as that one. (这本书不如那本书有趣。)
-
比较级:
形容词/副词比较级 + than(比...)- 构成规则：
- 一般直接加
-er(e.g.,tall->taller) - 以 e 结尾加
-r(e.g.,nice->nicer) - “辅音+y”变 y 为 i 再加
-er(e.g.,happy->happier) - 重读闭音节，双写末尾辅音再加
-er(e.g.,big->bigger) - 多音节和部分双音节词，用
more + 形容词/副词(e.g.,beautiful->more beautiful)
- 一般直接加
- 特殊变化：
good/well->better,bad/badly->worse,many/much->more,little->less,far->farther/further
- 构成规则：
-
最高级:
the + 形容词/副词最高级 + in/of...(在...中最...)- 构成规则与比较级类似，将
-er换为-est，more换为most。 - 特殊变化同上。
- 例句：He is the tallest student in our class. (他是我们班最高的学生。)
- 构成规则与比较级类似，将
过去进行时
- 结构：
was/were + 动词-ing - 用法：
- 表示过去某个特定时间点正在进行的动作。
- 时间标志：
at 8 o'clock yesterday,at that time,this time yesterday - 例句：I was doing my homework at 9 p.m. last night. (昨晚9点我正在做作业。)
- 时间标志：
- 表示过去一段时间内持续进行的动作。
例句：They were building a bridge from 2010 to 2025. (从2010年到2025年，他们一直在建一座桥。)
- 用
when引导的过去进行时和一般过去时连用，表示一个动作正在进行时，另一个动作发生。例句：I was walking home when it started to rain. (我正在走路回家，这时开始下雨了。)
- 表示过去某个特定时间点正在进行的动作。

be going to,情态动词,比较等级和过去进行时的用法和区别,多做时态和句型转换练习。 - 词汇是血肉： 按单元和话题背单词，并注意单词的词性（动词、名词、形容词、副词），结合例句记忆,不要孤立地背单词表。
- 听力是关键： 每天坚持听教材配套录音，或者简单的英文动画、歌曲,培养语感。
- 阅读是输入： 多读一些与课本难度相当的英语短文，可以巩固词汇,理解语法在语篇中的应用。
- 写作是输出： 每周尝试写一篇小短文，主题可以是“我的周末”、“我的朋友”、“我的爱好”等,尽量运用本单元学到的重点句型和词汇。
- 口语是应用： 和同学、朋友用英语进行简单的对话，或者自言自语描述正在做的事情,把学到的知识用起来。
