📚 IB Edexcel English: Grammar Mastery and Key Exam Points | IB Edexcel 英语：语法精讲 考点精讲

Grammar is the foundation of clear and effective communication in English. Both IB English B and Edexcel IGCSE English examinations place strong emphasis on grammatical accuracy, particularly in writing tasks. This guide covers essential grammar topics, common pitfalls, and targeted strategies to help you master the rules and apply them confidently in your exams.

语法是英语清晰有效沟通的基础。IB英语B和Edexcel IGCSE英语考试都非常注重语法准确性，特别是在写作任务中。本指南涵盖关键语法主题、常见陷阱以及有针对性的策略，帮助你掌握规则并在考试中自信应用。

1. Verb Tenses Overview | 动词时态概览

English verbs change form to indicate time (past, present, future) and aspect (simple, continuous, perfect, perfect continuous). In both IB and Edexcel exams, mixing tenses inconsistently is a common mistake that lowers scores. Knowing when to use each tense ensures your narrative or argument remains clear.

英语动词通过形式变化来表示时间（过去、现在、将来）和体（一般、进行、完成、完成进行）。在IB和Edexcel考试中，时态不一致的混用是导致扣分的常见错误。知道何时使用每种时态能确保你的叙述或论证清晰明了。

A quick-reference table of the twelve core tense forms can be helpful. For example, the Present Simple expresses habits (I study daily), while the Present Continuous expresses actions happening now (I am studying). The Past Simple narrates completed past actions (I studied yesterday), and the Past Continuous describes background actions (I was studying when she called). Future forms include ‘will’ for spontaneous decisions and ‘going to’ for plans.

快速参考表可以帮助记忆十二种核心时态形式。例如，一般现在时表达习惯（我每天学习），现在进行时表达正在发生的动作（我正在学习）。一般过去时叙述已完成的过去动作（我昨天学习），过去进行时描述背景动作（她打电话时我正在学习）。将来形式包括用 ‘will’ 表示自发决定，用 ‘going to’ 表示计划。

2. Present Tenses in Context | 现在时的语境运用

The Present Simple is often used for timetables and general truths (The sun rises in the east). In exam writing, it appears in summaries and descriptions of factual content. The Present Continuous can also express temporary situations or annoying habits with ‘always’ (He is always complaining).

一般现在时常用于时间表和普遍真理（太阳从东边升起）。在考试写作中，它出现在摘要和事实性内容的描述中。现在进行时也可以表达临时情况或与 ‘always’ 连用表示讨厌的习惯（他总是在抱怨）。

A key exam trap is overusing the Present Continuous where the Present Simple is required. For instance, stative verbs (know, believe, love) rarely take the continuous form. Thus, we say ‘I know the answer,’ not ‘I am knowing the answer.’ Checking stative verbs before writing will improve accuracy.

一个关键的考试陷阱是在需要用一般现在时的地方过度使用现在进行时。例如，状态动词（知道、相信、爱）很少用进行时态。因此，我们说 ‘I know the answer’，而不是 ‘I am knowing the answer’。在写作前检查状态动词将提高准确性。

3. Mastering the Past Tenses | 掌握过去时态

Past narratives demand careful tense sequencing. The Past Simple handles the main chain of events (She entered the room and sat down). The Past Perfect (had + past participle) is used for actions completed before a previous past moment (She had already left when he arrived). Many candidates forget the Past Perfect entirely and lose marks for timeline confusion.

过去叙事需要谨慎的时态顺序。一般过去时处理主要的事件链（她进入房间并坐下）。过去完成时（had + 过去分词）用于在过去某一时刻之前已经完成的动作（他到达时她已经离开了）。许多考生完全忘记了过去完成时，因时间线混乱而失分。

To avoid confusion, mentally order your events. If action A happened before action B in the past, use Past Perfect for A and Past Simple for B. Practicing with time markers like ‘after’, ‘before’, and ‘by the time’ will strengthen your grasp. Also, the Past Continuous is excellent for interrupted actions (I was watching TV when the phone rang).

为避免混乱，在心中给事件排序。如果动作A在动作B之前发生在过去，A用过去完成时，B用一般过去时。练习使用诸如 ‘after’、’before’ 和 ‘by the time’ 等时间标记将加强你的掌握。此外，过去进行时非常适合描述被打断的动作（电话响时我正在看电视）。

4. Perfect Tenses and Their Nuances | 完成时及其细微差别

The Present Perfect (have/has + past participle) connects the past to the present. It is used for experiences (I have visited Japan), recent events with ‘just’ (He has just finished), and unfinished time periods (I have eaten three apples today). In contrast, Past Simple is preferred for finished time (I ate three apples yesterday).

现在完成时（have/has + 过去分词）连接过去与现在。它
