新外研版英语六年级上册单元核心语法专项巩固 Unit 2 What’s your opinion？ 第一部分 核心语法梳理 本单元围绕“表达观点与看法”展开，核心语法包括以下三个方面： 语法一：表达观点的句型——In my opinion / I think... 基本用法 -In my opinion, ...意为“在我看来……”，是表达个人观点的正式用语，后接完整的句子。 -I think (that) ... 意为“我认为……”，其中 that 可以省略，后接完整的句子。 -I agree / I disagree. 意为“我同意 / 我不同意。”表达是否赞同他人观点。 -I agree with you. 意为“我同意你的看法。”with 后接人或观点。 核心结构： - In my opinion, reading is very important. 在我看来，阅读很重要。 - I think sports are good for us. 我认为运动对我们有好处。 - I agree with you. 我同意你的看法。 易错提醒：opinion 前用介词in，不能用 on 或 at。 ❌ On my opinion → ✅ In my opinion。 语法二：情态动词 should / shouldn’t 表达建议 基本用法 - should + 动词原形：表示“应该做某事”，用于提出建议或表达看法。 -shouldn’t + 动词原形：表示“不应该做某事”。 - should 是情态动词，没有人称和数的变化，后接动词原形。 核心结构： - We should help each other. 我们应该互相帮助。 - We shouldn’t watch too much TV. 我们不应该看太多电视。 - We should keep our classroom clean. 我们应该保持教室干净。 易错提醒：should 后必须接动词原形。 ❌ We should to help. → ✅ We should help. 语法三：because 引导的原因状语从句 基本用法 -because 意为“因为”，用来引导原因，说明理由。 - 结构：主句 + because + 原因。because 后接完整的句子。 - 回答 Why...? 的提问时，用Because... 回答。 核心结构： - I think sports are good for us, because they make us strong. 我认为运动对我们有好处，因为它们让我们强壮。 - I like reading because it is interesting. 我喜欢阅读，因为它很有趣。 易错提醒：because和so不能同时出现在一个句子中。❌ Because it is interesting, so I like it. → ✅ Because it is interesting, I like it. 或 It is interesting, so I like it. 语法四：动名词作主语 基本用法 -动名词（doing）作主语时，谓语动词用单数形式（is/makes 等）。 - 常见结构：Doing sth + is + 形容词 / makes + 宾语 + 形容词。 核心结构： - Reading is important for our study. 阅读对我们的学习很重要。 - Doing sports makes us strong. 做运动让我们强壮。 易错提醒：动名词作主语时，谓语不能加 -s 之外的复数形式。 ❌ Reading are good. → ✅ Reading is good. 第二部分 对应练习 练习一：用所给词的适当形式填空（10分） 1.
