### 高二英语必修一知识点精要

#### 1. 一般现在时
一般现在时是英语语法体系中的基石，通常以动词原形呈现。在运用时，需特别注意be动词和have动词的人称与数的变化，确保与主语保持高度一致。对于其他动词，若主语为第三人称单数，则必须遵循第三人称单数的变化规则。

（1）描述主语当前的状态或特征，如性格、能力等。例如：They are both tired and hungry.
（2）表达习惯性或周期性发生的动作与状态，常见时间状语包括always, often, sometimes, now and then, every day等。例如：She always goes to school by bus.
（3）陈述客观事实或普遍真理。例如：The earth moves around the sun.
（4）在时间状语从句和条件状语从句中，可表示将来的动作。例如：If it doesn’t rain tomorrow, we will go climbing.
（5）表示按规定预计要发生的动作，仅限于go, come, leave, start, stay, return, begin等动词。例如：The train leaves at 9 a.m.
（6）在以have或there开头的句子中，用动词go或come的一般现在时表示正在发生的动作。例如：Here comes the bus!

#### 2. 现在进行时
现在进行时主要用于描述以下三种情况：
（1）说话时正在进行的动作。例如：I am reading a book now.
（2）即将发生的或按计划安排好的动作，常与go, come, start, leave, return, arrive, stay, fly等表示运动方向的动词连用，句中通常包含表示将来的时间状语。例如：They are flying to London tomorrow.
（3）少数动词如go, come, leave, arrive, return, begin, do, die, lose等的现在进行时可以表示预计即将发生的动作。例如：It’s raining again.
（4）表示反复发生的动作。例如：He is always arriving late.

#### 3. 以-ing和-ed结尾的形容词
以-ed结尾的形容词主要用于描述人的精神状态或人对事物的态度或感受；而以-ing结尾的形容词则常带有“令人……的”意味，多用于形容物。例如：The movie was boring, but the book was interesting.
